Abstract:
Objective
To analyze the clinical outcomes of partially absorbable mesh versus standard polypropylene mesh in single-incision laparoscopic totally extraperitoneal hernia repair （TEP）.
Methods
A retrospective analysis was conducted on patients who underwent single-incision TEP at the Hernia and Abdominal Wall Surgery Department of Gansu Provincial People's Hospital between January 2020 and January 2021. Patients were categorized into an experimental group （partially absorbable mesh）and a control group （standard polypropylene mesh） based on the type of mesh used. Surgical time，intraoperative blood loss， length of hospital stay， seroma formation， foreign body sensation， chronic pain，mesh shrinkage diameter and shrinkage rate， and visual analogue scale （VAS） scores were evaluated and analyzed.
Results
There were no significant differences between the two groups in surgical time，intraoperative blood loss， length of hospital stay， or incidence of seroma （P＞0.05）. The average hospitalization cost in the experimental group was significantly higher （13 073.52±461.82） yuan than in the control group ［（10 518.20±473.62） yuan； P＜0.05］. Regarding postoperative complications， the experimental group had 2 cases of foreign body sensation （4.00%） and 3 cases of chronic pain （6.00%）， compared with 8 cases （16.00%） and 10 cases （20.00%）， respectively， in the control group. These differences were statistically significant （χ2=4.00， 4.33； P＜0.05 for both）. VAS scores decreased over time in both groups，with significantly lower scores in the experimental group on postoperative days 1 and 3 （P＜0.05）.Ultrasound measurements at 1， 3， 6， and 12 months postoperatively showed that the mesh shrinkage diameter and shrinkage rate were significantly better in the experimental group than in the control group（P＜0.05）.
Conclusion
Partially absorbable mesh demonstrates superior performance in single-incision TEP， with reduced mesh shrinkage diameter and shrinkage rate， as well as lower rates of postoperative foreign body sensation and chronic pain compared to standard polypropylene mesh. However， the cost is relatively higher， and its use should be prioritized in patients with adequate financial resources.
