To explore the influencing factors of complications after laparoscopic inguinal hernia repair (LIHR). A case retrospective analysis was conducted to collect clinical data of 212 patients with inguinal hernia who underwent LIHR in our hospital from July 2020 to October 2022. The patients were followed up by telephone and subsequent visit, and the enrolled patients were divided into the complication group (n = 36) and the non-complication group (n = 176) according to the presence or absence of complications. Chi-square test was used for univariate analysis, and the data with statistical significance between groups were included in the multivariate Logistic regression analysis model to investigate the risk factors for complications associated with LIHR. Common complications in patients undergoing LIHR included seroma, hematoma, urinary retention, unexplained chronic pain, etc. Body mass index (BMI), intraoperative blood loss, medical history time, hernia sac management, intraoperative adhesions, abnormal coagulation function, recurrent hernia, and hypertension were the influencing factors for complications after LIHR (χ2 = 6.809, 13.393, 5.371, 5.775, 4.128, 5.331, 4.920, and 6.675, P < .05). Multivariate analysis showed that BMI (odd ratio [OR] = 5.201, 95% confidence interval [CI] = 0.816–6.965, P < .05), intraoperative blood loss (OR = 2.512, 95% CI = 1.712–3.689, P < .05), intraoperative adhesions (OR = 6.352, 95% CI = 0.162–6.669, P < .05), abnormal coagulation function (OR = 6.352, 95% CI = 0.162–6.669, P < .05), recurrent hernia (OR = 2.208, 95% CI = 1.415–3.446, P < .05), and hypertension (OR = 3.365, 95% CI = 0.009–6.326, P < .05) were independent risk factors for complications after LIHR (P < .05). Common complications of LIHR included seroma, hematoma, urinary retention, etc. BMI, intraoperative blood loss, intraoperative adhesions, abnormal coagulation function, recurrent hernia, and hypertension were risk factors for complications after LIHR.
