ABSTRACT
Objective:To explore the risk factors of seroma after laparoscopic totally extraperitoneal hernia repair.Methods:The clinical data of 236 patients underwent laparoscopic totally extraperitoneal hernia repair from July 2018 to June 2021 in Jiaozhou Central Hospital of Qingdao City were retrospectively analyzed. The related risk factors of seroma after laparoscopic totally extraperitoneal hernia repair were analyzed.Results:Among 236 patients, the seroma occurred in 36 cases (seroma group), the incidence of seroma was 15.25%; no seroma occurred in 200 cases (non-seroma group). There were statistical differences in the duration of disease ≥5 years, scrotal hernia, internal inguinal ring defect ≥3 cm, rupture of hernia sac, experience of operators <5 years between 2 groups ( P<0.01 or <0.05); there were no statistical difference in age, body mass, type of patch, preoperative complications (including diabetes, chronic obstructive pulmonary disease and cardiac cerebrovascular disease) and operative time between 2 groups ( P>0.05). Multivariate Logistic regression analysis result showed that the duration of disease ≥5 years, scrotal hernia, rupture of hernia sac and experience of operators<5 years were independent influencing factors of seroma after laparoscopic totally extraperitoneal hernia repair ( OR = 5.147, 5.006, 0.044 and 3.315; 95% CI 1.513 to 17.516, 1.845 to 13.583, 0.008 to 0.240 and 1.029 to 10.679; P<0.01 or<0.05). Conclusions:The duration of disease ≥5 years, scrotal hernia, rupture of hernia sac and experience of operators<5 years are independent influencing factors of seroma after laparoscopic totally extraperitoneal hernia repair, and preoperative assessment of risk factors is helpful to reduce the incidence of seroma.
