To analyze the incidence and influencing factors of postoperative complications of laparoscopic inguinal hernia repair (IHR) in the elderly, and to formulate preventive measures.

A total of 567 elderly patients admitted to Qinhuangdao First Hospital from January 2018 to December 2021 after IHR surgery were selected as the research objects. According to the occurrence of postoperative complications, they were divided into the occurrence group (n=38) and the non-occurrence group (n=529), and the clinical data of the selected patients were analyzed. Univariate and logistic regression analyses were used to screen the influencing factors of postoperative complications of laparoscopic IHR in the elderly.

A total of 567 elderly patients after IHR surgery were included in this study, among whom postoperative complications occurred in 38 cases (6.70%), among which seroma was the highest (31.58%), chronic pain was the second (21.05%) and surgical site infection was the third (15.79%). Comparison of clinical data between the two groups showed differences in BMI, COPD, incarcerated hernia, hernia sac diameter, operation time, intraoperative blood loss, postoperative analgesic drug type and postoperative first urination time (P<0.05). Logistic regression analysis showed that BMI> 24 kg/m² (OR=3.031, 95% CI 1.421~6.466, P=0.004), COPD (OR=3.315, 95% CI 1.539~7.141, P=0.002), incarcerated hernia (OR=3.070, 95% CI 1.446~6.517, P=0.003), hernia sac diameter >5 cm (OR=3.416, 95% CI 1.577~7.401, P=0.002), Operative time >100 min (OR=3.423, 95% CI 1.561~7.506, P=0.002), intraoperative blood loss >10 ml (OR=2.626, 95% CI 1.233~5.591, P=0.012) and anesthesia used for postoperative analgesia (OR=3.509, 95% CI 1.641~7.503, P=0.001) were the risk factors affecting postoperative complications of IHR.

BMI>24 kg/m², COPD, trapped hernia, hernia sac diameter >5 cm, operation time >100 min, intraoperative blood loss >10 ml, postoperative analgesic drugs and anesthesia are the risk factors affecting postoperative complications of IHR. Medical staff can identify high-risk patients base on risk factors and take certain intervention measures to prevent postoperative complications of IHR.
