Outcome analysis of laparoscopic incisional hernia repair and risk factors for hernia recurrence in liver transplant patients

IntroductionIncisional hernia is a common complication after liver transplantation (LT). Immunosuppression, obesity, and use of steroids are known risk factors. The purpose of the retrospective study was to summarize and evaluate experiences and results of laparoscopic intraperitoneal onlay mesh (IPOM) hernia repair. MethodsWe reviewed our liver transplant patients over a seven-yr period with laparoscopic incisional hernia repair (LIHR) to direct our attention on risk factors for hernia recurrence after hernia repair. ResultsFifty-four patients after LT with incisional hernia were treated with laparoscopic repair, 42 male and 12 female patients of overall mean age of 589yr and body mass index (BMI) of 25 +/- 4kg/m(2). A total of 755 LTs were performed at our institution in this time period, resulting in 7.15% of patients undergoing laparoscopic hernia repair. The mean postoperative hospital stay after was nined. During the follow-up, nine recurrent hernias were noted (17%). BMI (p=0.001) and sirolimus as immunosuppressive therapy were significantly associated with hernia recurrence (p=0.014). ConclusionLIHR is a safe and feasible method to treat hernias after LT. BMI and sirolimus as immunosuppressive therapy are risk factors for recurrence of hernia after laparoscopic hernia repair.
