To analyze and evaluate the feasibility and safety of reconstruction following en bloc resection of the iliac-inguinal region in tumors involving both the anterior and lateral pelvis, based on the musculopectineal orifice repair principle.

A retrospective analysis was conducted on 6 patients who underwent en bloc resection and reconstruction of the iliac-inguinal region in the Department of Colorectal Surgery, the Second Affiliated Hospital of Naval Medical University from January to December 2024. The key technical strategies of musculopectineal orifice-based reconstruction were explored.

All 6 patients successfully completed the procedure, including resection and reconstruction of the inguinal ligament (6 patients), visceral sac reconstruction (5 patients), and resection with reconstruction of the external iliac vessels (4 patients ). The median operative time was 360 (300, 435) minutes, with median intraoperative blood loss of 450 (200, 600) ml. Postoperative outcomes included: median flatus passage at 4 (3, 5) days and median hospitalization duration of 6.5 (6, 14) days. Postoperative histopathological examination and follow-up confirmed R0 resection. There was no limb ischemia/necrosis, severe edema, abdominal wall hernia recurrence, intestinal obstruction, or enteric fistula after operation, and no other serious complications occurred.

Musculopectineal orifice repair principle-guided reconstruction after en bloc resection of the iliac-inguinal region demonstrates both technical feasibility and clinical safety.

To evaluate the safety, feasibility, and clinical efficacy of a basement membrane biopatch visceral protective sac in preventing enteroatmospheric fistula during negative pressure-assisted temporary abdominal closure (NPAAC).

A retrospective descriptive study was conducted on 5 patients who underwent NPAAC with the application of the basement membrane biopatch for visceral protection at the Second Affiliated Hospital of Naval Medical University from June 2024 to April 2025. Patient demographics, complication rates, abdominal wound healing status, and hospital length of stay were analyzed.

In this study, there were 5 patients, including two males and three females, with a median age of 57.0 (IQR: 46.0-60.5) years and a median body mass index of 24.8 (IQR: 22.4-27.1) kg/m². The median time from initial surgery to wound opening due to infection was 5.0 (IQR: 4.5-6.0) days. Prior to NPAAC, three patients underwent wound debridement and peritoneal lavage during exploratory laparotomy, while two received temporary ileostomy plus peritoneal lavage during exploratory laparotomy. All five patients survived following NPAAC treatment. The median number of negative- pressure therapy sponge changes was 3.0 (IQR: 2.0-6.0) times. Gastrointestinal function recovery occurred at a median of 3.0 (IQR: 2.0-8.3) days, and the negative-pressure device was removed after a median of 9.0 (IQR: 7.5-31.0) days. Definitive tension-reducing suture closure was performed in three patients, one received split-thickness skin grafting, and one underwent staged abdominal wall reconstruction following stamp grafting. The median total hospital stay was 25.0 (IQR: 22.0-47.5) days. No enteroatmospheric fistula occurred during treatment. Complications mainly included wound bleeding, urinary tract infection, gastric retention, and pulmonary infection, all of which resolved with drug treatment. During a median follow-up of 7.0 (IQR: 4.0-10.5) months, all abdominal wounds healed. One patient developed an incisional hernia, which was managed conservatively.

This study demonstrates that visceral protection with a basement membrane biopatch before NPAAC is a safe and feasible approach, which can effectively reduce the occurrence of enteroatmospheric fistula.

To evaluate the efficacy and safety of using a basement membrane biological hernia repair mesh for retroperitoneal and pelvic floor reconstruction and abdominopelvic isolation in preventing and managing post-pelvic exenteration (PE) empty pelvic syndrome.

Data were collected from 31 patients who underwent PE with retroperitoneal and pelvic floor reconstruction using a basement membrane biological hernia repair mesh at the Department of Anorectal Surgery, the Second Affiliated Hospital of Naval Medical University, between November 16, 2022, and March 27, 2024. A retrospective descriptive study was conducted to analyze the overall incidence of complications related to empty pelvic syndrome within 90 days after surgery (including small bowel obstruction, persistent deep pelvic effusion, pelvic infection with abscess or sinus tract formation), time to recovery of bowel function, time to resolution of empty pelvic syndrome, and the incidence of complications classified as Clavien-Dindo grade≥III.

Among the 31 patients, the overall incidence of complications related to empty pelvic syndrome within 90 days postoperatively was 3.2% (1/31). This single case was small bowel obstruction. Within 90 days after surgery, 3 patients died (1 died of pulmonary embolism; 2 died of tumor metastasis and disease progression). For the remaining cases, the recovery time of empty pelvic syndrome was (17.9±10.4) days, and the intestinal function recovery time was (7.7±5.6) days.

The application of a basement membrane biological hernia repair mesh in PE for retroperitoneal and pelvic floor reconstruction, as well as for isolating the abdominal and pelvic cavities, is safe and effective. The incidence of complications related to empty pelvic syndrome within 90 days after surgery is low.

To evaluate the safety and efficacy of a novel basement membrane–small intestinal submucosa (BM-SIS) composite biopatch for the repair of contaminated or infected inguinal hernias.

This single-center retrospective study included 24 patients with contaminated or infected inguinal hernias who underwent laparoscopic transabdominal preperitoneal (TAPP) repair in the Department of Gastrointestinal Surgery, Shanghai Pudong Hospital, between January 2023 and December 2024. All surgeries were performed using the BM-SIS composite biopatch. Perioperative and postoperative follow-up data were collected to analyze the incidence of postoperative complications and hernia recurrence.

All surgeries were completed successfully. The mean operative time was (112.92±36.43) min, and the median postoperative hospital stay was 7 (6, 10) days. There were no cases of mesh removal due to infection during the perioperative period. Postoperative complications included one case of seroma (4.2%), one case of incisional hernia (4.2%), one case of adhesive intestinal obstruction, and one case of small bowel perforation; all were managed with conservative or surgical treatment. No hernia recurrence was observed during a median follow-up of 14.5 (8.5, 21.5) months.

The BM-SIS composite biopatch demonstrates structural innovation, combining anti-infection properties and mechanical stability, making it a safe and effective clinical option for contaminated or infected inguinal hernia repair. However, long-term efficacy warrants validation through larger-scale studies.

To explore the clinical efficacy, safety, and operational standards of Endoluminal Vacuum-Assisted Closure (EVAC) combined with Vacuum-Assisted Closure (VAC) in treating open abdomen complicated with enteroatmospheric fistula.

This study employed a descriptive case series design. A retrospective analysis was conducted on the clinical data of 13 patients with open abdomen and enteroatmospheric fistula admitted to Jiangyin People's Hospital from January 2020 to December 2024. All patients received EVAC (polyurethane sponge placement via endoscopy/ percutaneously) combined with VAC (polyurethane sponge covering the open wound). Main observation indicators: length of hospital stay, need for reoperation; Secondary indicators: changes in inflammatory markers (WBC, C-reactive protein, procalcitonin), improvement in nutritional status (albumin).

All 13 patients achieved wound coverage with skin grafting and management of enterocutaneous fistulas to the point of self-care. No patient required reoperation due to failure in wound or enterocutaneous fistula management. The median hospital stay was 42 (35, 98) days for the 13 patients. Changes in inflammatory and nutritional indicators before and after treatment: WBC [decreased from (19.8±8.1)×10⁹/L to (7.4±2.6)× 10⁹/L], C-reactive protein [decreased from (174.9±55.5) mg/L to (15.6±4.7) mg/L], and procalcitonin [significantly decreased from (7.1±4.4) ng/ml to (0.6±0.3) ng/ml] (P<0.01); albumin [significantly increased from (23.3±3.1) g/L to (35.6±2.8) g/L] (P<0.05). Complications: 6 cases of pain (46.2%), 10 cases of sponge displacement and obstruction (76.9%), 2 cases of mucosal bleeding (15.4%), 1 case of wound infection (7.7%), and 8 cases of adhesive intestinal obstruction (61.5%). No cases of intestinal perforation, major bleeding, or death occurred.

EVAC combined with VAC effectively controls infection, promotes granulation tissue growth, reduces wound contamination, and achieves enteral nutrition through a "internal drainage+external coverage" dual mechanism. It is a safe and effective approach for treating open abdomen with enteroatmospheric fistula.

To evaluate the clinical efficacy of negative-pressure ostomy techniques in managing enteroatmospheric fistula and stoma mucocutaneous separation.

A retrospective case series study was conducted on clinical data of 11 patients with enteroatmospheric fistula and stoma mucocutaneous separation treated with negative-pressure ostomy techniques in the Department of General Surgery, Jiangyin people's Hospital from August 2022 to August 2024. Primary outcomes included digestive fluid management and wound contamination, while secondary observation indicators included wound healing status, inflammatory markers, and albumin levels.

The study included 11 patients, 6 males and 5 females, with a mean age of (62.3±12.5) years. Among them, 3 cases had enteroatmospheric fistulas, and 8 cases had stoma mucocutaneous separations. All patients underwent negative-pressure ostomy therapy for a mean duration of (26.1±10.7) days. After the treatment, all wound infections were effectively controlled, with healthy granulation tissue formation. Inflammatory markers (white blood cells, C-reactive protein) significantly decreased compared to those before treatment (P<0.05). No complications such as wound bleeding, new-onset digestive tract fistula, or foreign body retention were observed. The mean follow-up duration was (24±6.5) months. By the last follow-up on August 20, 2025, no cases of digestive tract stenosis, fistula recurrence, or abscess formation were detected.

Negative- pressure ostomy techniques can effectively manage leakage fluid, reduce peristomal wound contamination and infection, and promote granulation tissue regeneration.

To compare the clinical efficacy of the Da Vinci robotic system and laparoscopic Sugarbaker repair for parastomal hernia, and to analyze the differences in effectiveness and underlying causes between the two surgical techniques.

A retrospective case-control study was conducted by analyzing the clinical data of patients who underwent Sugarbaker repair for parastomal hernia in the Department of Hernia and Abdominal Wall Surgery at Tianjin People’s Hospital between February 2023 and February 2025. A total of 56 patients were enrolled and divided into two groups according to the surgical approach: the robotic group (15 cases) and the laparoscopic group (41 cases). The two groups were compared in terms of preoperative body mass index (BMI), long diameter of the hernia ring, operative time, intraoperative blood loss, numerical rating scale (NRS) pain score on the first postoperative day, time to first flatus and defecation, postoperative hospital stay, and total hospitalization cost. Postoperative follow-up was performed to observe the recurrence of parastomal hernia and the occurrence of intestinal obstruction.

T There were no statistically significant differences between the two groups in preoperative BMI or hernia ring diameter. All operations were completed as planned without conversion to open surgery, change of surgical procedure, or occurrence of severe surgery-related complications. Compared with the laparoscopic group, the robotic group had a longer median operative time [M (IQR): 170 (60) min vs 105 (53) min] and higher median total hospitalization cost [70 562 (3 547) CNY vs 60 121 (12 341) CNY], but a shorter median postoperative hospital stay [4 (1) days vs 5 (2) days], shorter median time to defecation [3 (2) days vs 4 (1) days], and lower median NRS pain score on the first postoperative day [2 (1) points vs 5 (2) points]; all differences were statistically significant (P<0.05). The postoperative follow-up duration ranged from 1 to 24 months, with a median of 12 months. There were no significant differences between the two groups in the recurrence rate of parastomal hernia or the incidence of intestinal obstruction (P>0.05).

Both robotic and laparoscopic Sugarbaker repair for parastomal hernia are safe and feasible. The Da Vinci robotic approach offers advantages in reducing postoperative pain and facilitating rapid postoperative recovery, whereas laparoscopy demonstrates advantages in operative time and overall hospitalization cost.

To compare the short-term outcomes of laparoscopic transabdominal preperitoneal repair (TAPP) and laparoscopic intraperitoneal onlay mesh (IPOM) repair for umbilical hernia.

A retrospective analysis was conducted on 49 patients with umbilical hernia treated at the Second Affiliated Hospital of Xi'an Jiaotong University from July 2023 to December 2024. Patients were divided into two groups according to the surgical approach they underwent: the TAPP group (25 cases) and the IPOM group (24 cases). Operation time, intraoperative blood loss, postoperative hospital stay, hernia recurrence, surgical site/mesh infection, seroma, foreign body sensation, and postoperative pain were compared.

There were no statistically significant differences between the two groups regarding baseline characteristics, intraoperative blood loss, postoperative hospital stay, recurrence rate, surgical site/mesh infection rate, or seroma formation rate. However, the TAPP group demonstrated a longer operative time [ (126.96±13.92) min vs. (91.38±6.23) min, P<0.05], while showing significantly lower postoperative visual analog scale (VAS) scores for pain [(2.32±0.56) vs. (4.33±1.01)] and reduced incidence of foreign body sensation (4% vs. 25%, P<0.05).

Although TAPP prolongs operative time, it can significantly improve the patient's postoperative recovery experience. Its safety and short-term efficacy are comparable to IPOM, providing an alternative surgical option for umbilical hernia repair. Further large-scale studies with long-term follow-up are needed to validate these advantages.

To investigate and compare the efficacy of composite mesh and biological mesh in laparoscopic intraperitoneal onlay mesh (IPOM) repair for umbilical hernia.

This single-center retrospective cohort study consecutively enrolled 93 patients with umbilical hernia who underwent laparoscopic IPOM repair in the Department of Gastrointestinal Surgery, Jinan Central Hospital, from July 2018 to September 2024. Based on the type of mesh used intraoperatively, patients were divided into the composite mesh group (n=43) and the biological mesh group (n=50). All patients underwent laparoscopic IPOM repair. Data collected included operative time, postoperative time to first flatus, postoperative hospital stay, incidence of infection, recurrence, and chronic pain. Statistical analyses were performed using SPSS version 25.0.

There were no statistically significant differences between the two groups in terms of sex, age, body mass index, and hernia ring diameter (P>0.05). Similarly, no significant differences were observed between the two groups with respect to operative time, postoperative hospital stay, incidence of infection, or incidence of chronic pain (P>0.05). Notably, the postoperative time to first flatus was significantly shorter in the biological mesh group compared with the composite mesh group [(1.50±0.29) days vs. (2.30±0.67) days, P<0.001]. Recurrence occurred in two cases(4.0%) in the biological mesh group and in none in the composite mesh group; however, the difference in recurrence rate between the two groups was not statistically significant (P=0.497).

Both types of mesh demonstrated comparable surgical outcomes. The biological mesh group showed an advantage in terms of postoperative time to first flatus, although its recurrence rate warrants further attention.

To construct a nomogram model to predict the risk of intestinal necrosis in patients with incarcerated inguinal hernia.

Clinicopathological data of patients diagnosed with incarcerated inguinal hernia in the Department of Gastrointestinal Surgery, Affiliated Huai’an Hospital of Xuzhou Medical University, were retrospectively analyzed. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for intestinal necrosis in incarcerated inguinal hernia. A corresponding nomogram prediction model was then established.

Tenderness in the groin area (OR=9.164, 95% CI=2.540-33.066), intestinal obstruction (OR=6.781, 95% CI=1.568- 29.330), C-reactive protein (CRP; OR=1.023, 95% CI=1.009-1.037), and neutrophil count (OR=1.253, 95% CI=1.073-1.463) were identified as independent risk factors for intestinal necrosis in incarcerated inguinal hernia, whereas prealbumin (OR=0.992, 95% CI=0.986-0.998) was identified as an independent protective factor. Based on the five independent risk and protective factors, a nomogram model was established to predict the risk of intestinal necrosis in incarcerated inguinal hernia. The discrimination ability of the model was evaluated using the ROC curve. The area under the ROC curve was 0.906 (95% CI=0.851-0.962; P<0.05). The calibration curve showed good agreement with the ideal curve, and the decision curve analysis demonstrated the clinical utility of the model.

Tenderness in the groin area, intestinal obstruction, CRP, and neutrophil count are independent risk factors, whereas prealbumin is an independent protective factor for intestinal necrosis in incarcerated inguinal hernia. The established nomogram model demonstrated high sensitivity, specificity, and clinical applicability.

To compare the clinical efficacy and safety of laparoscopic trans-abdominal preperitoneal hernia repair (TAPP) and Lichtenstein's tension-free hernia repair in the treatment of incarcerated inguinal hernia.

Clinical data of 118 patients with incarcerated inguinal hernia who underwent hernia repair surgery at Xiaogan No.1 People's Hospital in Hubei Province from January 2019 to December 2023 were retrospectively collected. The patients were divided into two groups based on the surgical method: the TAPP group (56 cases) underwent TAPP surgery, and the Lichtenstein group (62 cases) underwent Lichtenstein's procedure. The hospital stay, operative time, intraoperative blood loss, and postoperative pain visual analog scale (VAS) scores were compared between the two groups. Postoperative complications and follow-up recurrence rates were recorded and analyzed.

There was no statistically significant difference in operative time and postoperative recurrence rates between the TAPP group and the Lichtenstein group (P>0.05). The TAPP group showed significantly lower intraoperative blood loss, postoperative pain scores, and surgical complication rates compared to the Lichtenstein group, with statistically significant differences (P<0.05).

Both TAPP and Lichtenstein procedures are safe and effective for the treatment of incarcerated inguinal hernia. TAPP demonstrates advantages in terms of intraoperative blood loss, postoperative pain, and postoperative complications.

To analyze the efficacy of total pelvic floor reconstruction via laparoscopy for pelvic organ prolapse (POP).

Ninety POP patients with POP admitted to Huai'an First Hospital between January 2019 and January 2022 were enrolled and divided into a control group (44 cases) and an observation group (46 cases) according to surgical methods. Patients in the control group underwent vaginal hysterectomy combined with anterior and posterior vaginal wall repair. Patients in the observation group underwent total pelvic floor reconstruction with titanium-coated polypropylene (TiLOOP) mesh implantation via laparoscopy. Surgical outcomes, pain levels, pelvic floor muscle strength, quality of life, complications, and prognosis were compared between the two groups.

The observation group showed less intraoperative blood loss (24.38±7.14) ml, shorter indwelling catheter time (2.39±0.62) days, and shorter postoperative hospital stay (5.84±1.52) days compared to the control group (46.22±10.76) ml, (3.06±0.72) days, (7.17±1.98) days. The operation time (131.29±28.47) minutes was longer than that of the control group (98.54±21.36) minutes (P<0.05). The observation group had shorter self-perceived pain duration (3.86±0.45) days and lower visual analogue scale (VAS) scores at 12 hours postoperatively (4.29±0.47) points versus the control group (4.17±0.59) days, (4.66±0.79) points (P<0.05). At 6 months postoperatively, the observation group exhibited higher myoelectric potential (14.19±2.13) μV, static tension (156.49±21.83) g/cm², and dynamic tension (231.56±28.44) g/cm² than the control group (12.98±1.95) μV, (144.92±22.64) g/cm², (216.47±27.08) g/cm² (P<0.05). At 12 months postoperatively, the observation group had lower pelvic organ prolapse distress inventory 6 (POPDI-6) (6.83±1.51) points, colorectal-anal distress inventory 8 (CRADI-8) (2.27±0.62) points, and urinary distress inventory 6 (UDI-6) (6.76±1.13) points than the control group (7.65±1.79) points, (2.61±0.83) points, (7.43±1.89) points (P<0.05). No statistically significant differences were found in complication rates or POP recurrence rates between the two groups (P>0.05).

Total pelvic floor reconstruction with TiLOOP mesh via laparoscopy reduces intraoperative bleeding, shortens postoperative recovery time, alleviates pain, enhances pelvic floor muscle strength, improves quality of life, and does not increase complications compared to traditional surgery.

To explore the effect of electrical stimulation biofeedback combined with Kegel exercises on the postoperative rehabilitation of patients with stage II-III uterine prolapse.

This was a retrospective cohort study. The clinical data of 90 patients with uterine prolapse admitted to Wuxi People's Hospital from June 2020 to March 2024 were retrospectively analyzed and the patients were divided into an experimental group (n=46, electrical stimulation biofeedback+Kegel exercise) and a control group (n=44, Kegel exercise) according to different treatment plans. The perioperative indicators, levels of endocrine-related factors, pelvic floor structural parameters, electrophysiological indicators of pelvic floor muscles, pelvic floor muscle strength, urinary function, quality of life scores, and clinical efficacy of the two groups of patients were compared.

There was no statistically significant difference in the perioperative indicators (operation time, intraoperative blood loss, postoperative vaginal length, and indwelling days of urinary catheters between the two groups of patients (t=1.202, 1.115, 1.650, 1.816, P>0.05). Before treatment, there were no statistically significant differences in the levels of endocrine factors and pelvic floor structural parameters between the two groups of patients (P>0.05). After the end of treatment, the levels of neuropeptide Y and follicle-stimulating hormone in the experimental group were higher than those in the control group (t=2.107, 2.270; P=0.038, 0.026). All pelvic floor structural parameters in the experimental group, including the urethral rotation angle, bladder neck mobility, bladder posterior angle, anterior and posterior diameter of anal levator hiatus, left and right diameter of anal levator hiatus, and area of anal levator hiatus, were lower than those in the control group (t=2.733, 2.228, 2.221, 2.156, 2.156, 2.977, P<0.05). The maximum potential value of type Ⅰ pelvic floor muscle fibers and the average potential value of type Ⅱ pelvic floor muscle fibers in both groups increased with prolonged treatment time, with statistically significant differences. Additionally, the differences in the change trends of the two groups at different time points were statistically significant (For type Ⅰ fibers: F_time/P_time=384.515/<0.001; F_group/P_group=0.182/0.670; F_interaction/P_interaction=5.446/0.005; For type Ⅱ fibers: F_time/P_time=294.549/<0.001; F_group/P_group=3.831/0.051; F_interaction/P_interaction=4.604/0.011). There were no statistically significant differences in pelvic floor muscle strength between the two groups of patients before surgery and at 3 months after treatment. After the end of treatment, the pelvic floor muscle strength of the experimental group was superior to that of the control group (Z=2.471, P<0.05).The residual urine volume and urinary incontinence frequency of patients in both groups decreased gradually with the extension of treatment time, and there were statistically significant differences in the inter-group comparison (For residual urine volume: F_time/P_time=2940.820/<0.001; F_group/P_group=4.346/0.038; F_interaction/ P_interaction=0.299/ 0.742; For urinary incontinence frequency: F_time/P_time=947.226/<0.001; F_group/P_group= 3.999/0.047; F_interaction/P_interaction=0.555/0.575). Comparison of the scores of incontinence life quality questionnaire between the two groups of patients before treatment showed no statistically significant difference. After the end of treatment, the scores of incontinence life quality questionnaire in terms of behavioral restriction, psychological impact, and social impact in the experimental group were higher than those in the control group (t=2.426, 3.047, 2.371; P<0.05). There was no statistically significant difference in the comparison of the total effective rate of treatment between the two groups of patients (χ²=2.007, P=0.157).

Electrostimulation biofeedback combined with Kegel exercise is effective in the treatment of uterine prolapse, which can optimize the pelvic floor myoelectric value, promote the pelvic floor function recovery, effectively improve the clinical symptoms of patients and improve the quality of life.

To conduct analysis of the CT manifestations of direct inguinal hernias with hernia sac entering the scrotum.

Retrospective analysis of clinical and CT imaging data of 13 patients with inguinal hernia sac entering the scrotum admitted to Yongkang First People's Hospital and Yongkang Hospital of Traditional Chinese Medicine from January 2018 to April 2024. Retrospective analysis of clinical and CT imaging data from 13 cases of direct inguinal hernias with hernia sac entering the scrotum. CT images were examined to record the position of the hernia sac, the display of inferior epigastric arteries and veins, and their relationship with the hernia sac neck, the lateral crescent sign presence, the hernia sac maximum cross-sectional diameter, and the depth of the hernia sac entering the scrotum.

All patients' hernia sacs were crossed over the pubic tubercle using the cross method, with the anterior outer edge of the pubic tubercle as the marker point for the Y-axis (vertical line). In all cases, the inferior epigastric arteries and veins were visible. the neck of the hernia sac was located on the inner side of the inferior epigastric arteries and veins. The lateral crescent sign was observed in 9 cases. The maximum cross-sectional diameter of the hernia sac ranged from 44.0 to 64.5 mm, with an average of (52.2±5.4) mm. In three case, the lower pole of the hernia sac reached the level of the testicle, while in ten cases, it was located above the level of the testicle.

Direct inguinal hernias with hernia sac entering the scrotum can be easily misdiagnosed as indirect inguinal hernias. The relationship between the inferior epigastric arteries and veins and the hernia sac neck, along with the presence of the lateral crescent sign, are key points for differentiation. Delabrousse E's "cross" crossmethod is not suitable for distinguishing inguinal hernias with hernia sac entering the scrotum.

To analyze the differences in efficiency and patient satisfaction of different preoperative preparation methods for patients with abdominal wall hernia after they enter the operating room.

A retrospective analysis was conducted on clinical data of patients undergoing elective abdominal wall hernia surgery in Beijing Chaoyang Hospital, Capital Medical University between January 2018 and January 2020. Patients were divided into a decentralized group and a centralized group based on the establishment of a preoperative preparation room in our center in January 2019. Patients in the decentralized group underwent preoperative preparation and waited for surgery at the entrance of the operating room after entering, while patients in the centralized group entered a preoperative preparation room for preoperative preparation and waiting after entering the operating room. The preoperative preparation time and patient satisfaction were compared between the two groups to determine if there were differences.

There were 307 patients in the decentralized group and 341 patients in the centralized group, and all patients successfully completed preoperative preparation. There was no statistically significant difference in baseline characteristics between the two groups (P>0.05). The preoperative preparation time was (60.59±15.62) minutes in the decentralized group and (62.17±15.03) minutes in the centralized group, with no statistically significant difference between the two groups (P>0.05). Patient satisfaction was 72.31% in the decentralized group and 87.98% in the centralized group. There was a statistically significant difference in patient satisfaction between the two groups (χ²=15.805, P<0.001).

The preoperative preparation room can significantly improve patient satisfaction. Although centralized preoperative preparation in the preoperative preparation room did not effectively shorten the preoperative waiting time, it provided patients with a more stable preoperative waiting time and higher consistency of preoperative education, which could increase the degree of homogenization.

To investigate the interventional effect of comfort nursing combined with external application of rhubarb and mirabilite on scrotal edema following inguinal hernia surgery.

A retrospective analysis study was conducted among 40 patients who developed postoperative scrotal edema after inguinal hernia repair and were admitted to Funan County Hospital of Traditional Chinese Medicine between January 2022 and August 2024. All patients received a standardized comfort nursing program, including posture management, optimization of the ward environment, stratified education for high-risk patients, multidisciplinary collaboration for prevention, and postoperative dynamic monitoring and intervention. In addition, all patients were treated with an external preparation of rhubarb and mirabilite (ratio 1:3). The incidence and degree of scrotal edema, postoperative pain, and patient satisfaction were observed and evaluated.

All patients experienced relief of scrotal distension and discomfort within 6-8 hours after the application of rhubarb-mirabilite compresses. Therefore, the combined intervention achieved a 100% effective rate in all patients with scrotal edema, and no cases of ineffectiveness were observed. Postoperative pain grading indicated that no patients experienced severe pain, and only two had moderate pain. During the 3-month postoperative follow-up, all patients reported satisfaction with the care received, with no cases of dissatisfaction.

Comfort nursing combined with external application of rhubarb and mirabilite can effectively alleviate postoperative scrotal edema after inguinal hernia repair, reduce pain, and enhance patient satisfaction. This combined approach demonstrates significant clinical value and is worthy of wider application.

Ileostomy is a common operation in abdominal surgery, which is suitable for the treatment of various digestive diseases. In clinical practice, this operation has important therapeutic significance. Although some of the common complications of ileostomy are well known, some potential effects have not received enough attention and may have an important impact on patients' lives. Therefore, there is still some controversy about whether the procedure should be popularized. In this paper, the effects of ileostomy on the pathophysiological functions of related organs, intestinal microbes, electrolytes, and the social and psychological aspects of patients with stomas were reviewed. In order to have some reference for the majority of medical staff and scientific research workers.

Incarcerated inguinal hernia, as a common surgical acute abdominal condition, is increasingly valued by clinical physicians due to its fast progression, long hospital stay, high mortality rate and high incidence of postoperative complications. For diagnosed patients with incarcerated hernia, surgical treatment should be arranged as soon as possible, but there is still controversy over the choice of surgical method, whether to place meshes after surgery, and whether to indwelling drainage tubes after the operation. This article reviews the current treatment of incarcerated inguinal hernia by consulting relevant literature, in order to provide guidance for clinical practice.

Hernia is one of the common diseases of the abdominal wall, and hernia repair surgery is the most common clinical procedure for treating such diseases. Both open surgery and laparoscopic hernia repair usually require the use of a hernia mesh. Different patch materials have different characteristics and indications. With the continuous advancement and development of material science, hundreds of types of hernia patches have been applied clinically. The purpose of this article is to introduce and analyze the current research progress and clinical application benefits of various types of hernia mesh materials, and to look forward to the future development direction.

To evaluate the efficacy of a three-stage teaching model based on the Outcome-Based Education (OBE) concept in training resident physicians for laparoscopic hiatal hernia repair (LHHR).

A prospective randomized controlled trial was conducted, enrolling 40 resident physicians at Beijing Chaoyang Hospital Hernia and Abdominal Wall Surgery Center from June to December 2024. Sample size was estimated based on a two-sample mean comparison (α=0.05, power=80%), requiring 20 participants per group. Randomization was performed using the Fisher–Yates random number table (1983 edition) to generate 40 unique numbers (01-40), which were assigned sequentially according to enrollment; the first 20 were allocated to the traditional teaching group (n=20) and the remaining 20 to the OBE group (n=20). The traditional group received conventional training through self-directed learning and observation and the OBE group underwent a three-stage progressive training program. Outcomes were evaluated via theoretical tests, surgery completion rates, operative time, intraoperative metrics, and satisfaction surveys.

The OBE group scored significantly higher in theoretical assessments (P<0.001) and demonstrated significantly higher independent LHHR completion rates (75% vs. 30%, P=0.004) compared to the traditional group. The median operative time in the OBE group was 27.5 minutes shorter (P=0.023). No differences were observed in intraoperative blood loss or postoperative hospitalization (P>0.05). The OBE group reported superior clinical decision-making efficiency and training satisfaction (P=0.016).

The OBE-based three-stage teaching model effectively enhances resident physicians' theoretical mastery, surgical competency, and operative efficiency in LHHR. Its phased objectives and dynamic feedback mechanism establish a standardized framework for specialized surgical training, offering significant clinical implementation potential.

To explore the effectiveness of laparoscopic surgery simulator for education and training in transabdominal preperitoneal (TAPP) hernia repair.

A total of 41 trainees who received TAPP surgical training at the Department of Hernia and Abdominal Wall Surgery, Beijing Chaoyang Hospital, Capital Medical University, between January 2018 and December 2023 were included. According to the training methods, trainees were divided into an observation group (n=29) and a control group (n=12). The observation group received a three-week laparoscopic surgery simulator training program, while the control group received traditional instruction through course materials, video lectures, and intraoperative teaching. The TAPP peritoneal suturing skills of trainees in both groups were evaluated before and after the training, and feedback on the training course was collected.

The assessment of TAPP peritoneal suturing skills showed that after training, the simulator group achieved significantly higher scores than the traditional teaching group (P<0.05). After training, confidence in performing the procedure in clinical practice increased in both groups, with a statistically significant difference between the two groups (P<0.05).

Laparoscopic surgery simulators can significantly improve trainees' laparoscopic surgery skills and enhance their confidence in performing laparoscopic surgery.

Mesh infection complicated by enteric fistula following incisional hernia repair constitutes a life-threatening complication, which often results in prolonged non-healing of the abdominal wall incision and significantly impairs patients' quality of life. This case report presents a patient with an incarcerated incisional hernia, in whom intraoperative exploration revealed necrosis of the incarcerated intestinal segment. Simultaneous resection of the necrotic intestine and mesh repair of the hernia were performed during the same operation. Postoperatively, the patient developed an incision infection and subsequent mesh infection, which eventually progressed to enteric fistula and recurrence of incisional hernia. The disease course lasted for 4 years, and the patient achieved complete recovery following reoperation. This case aims to enhance clinicians' understanding of such complications and provide valuable reference for their clinical management.

This paper provides a detailed analysis of a case of bilateral inguinal hernia combined with cryptorchidism. The patient is 59 years old, with a social gender of "female," and was admitted for bilateral inguinal hernia treatment, undergoing laparoscopic trans-abdominal preperitoneal hernia repair. During the surgery, bilateral inguinal masses were identified, and postoperative pathology confirmed cryptorchidism. Further examination revealed a congenital absence of the uterus and adnexa. The patient exhibited well-developed female breasts (E-cup) and adult female vulvar characteristics. By comprehensively elaborating the clinical features, diagnostic and treatment process, various examination results, and in-depth discussion of this case, this study provides valuable reference for clinicians when dealing with complex disorders of sex development and hernia-related conditions, thereby enhancing the understanding and management of such rare diseases.
