P-052 RISK FACTORS FOR PERITONEAL TEARS DURING LAPAROSCOPIC EXTRAPERITONEAL HERNIA REPAIR

Abstract

Abstract Background Peritoneal tears (PTs) are not uncommon during the course of laparoscopic total extraperitoneal (TEP) repair of groin hernias. There are several mechanisms involved in the occurence of PTs during the course of the operation. There are many studies about the causes of peritoneal tears. Detection of independent risk factors in peritoneal tear formation may identify patients who will benefit from elective inguinal hernia repair in laparoscopic extraperitoneal hernia surgery. Methods Between April 2018 and december 2022, 518 consecutive patients undergoing 575 TEP repair surgery were recruited by the retrospective study. They were divided into two groups as with and without peritoneal tear. Patient characteristics, operative data, and postoperative outcomes were compared between patients with and without peritoneal tear. Risk factors for peritoneal tear were evaluated by univariate and multivariate analyses. Results The overall incidence of peritoenal tear was 19.7% (n=97). The median age was 45 years (18 to 83) and body mass index was 25.7 kg/m2 (15.67 to 35.20). Significant clinical factors associated with peritoneal tear included such as hernia type, previous hernia surgery, large hernial defects, presence of scrotal hernia, and the defect size of inguinal hernia. Multivariate analysis identified independent risk factors for peritoneal tear as indirect hernia type and previous hernia surgery. Conclusion Peritoneal tears is a major complication seen during TEP repair surgery and its incidence varies depending on many factors. Previous hernia surgery and indirect inguinal hernia the risk for peritoneal tears from during TEP repair.
