Is the Laparoscopic Approach Feasible for Reduction and Herniorrhaphy in Cases of Acutely Incarcerated/Strangulated Groin and Obturator Hernia?: 17-Year Experience from Open to Laparoscopic Approach.

Purpose: Management strategies for acutely incarcerated/strangulated groin and obturator hernias may differ from institution to institution, although, conventionally, the open approach has been used. Recently, laparoscopic transabdominal preperitoneal (TAPP) repair and totally extraperitoneal (TEP) repair have become commonly used operative procedures for the repair of groin hernias. It is unclear whether laparoscopic reduction and herniorrhaphy can be successfully accomplished in all cases. This study was aimed at assessing the effectiveness of laparoscopic treatment. Methods: We conducted a prospective clinical trial of the laparoscopic approach from December 2011 and comparatively analyzed the surgical outcomes between the open and laparoscopic approaches for incarcerated/strangulated hernias seen from December 2000 to March 2017. Results: The open approach for repair was used in 54 patients (50.9%) and the laparoscopic approach in 52 patients (49.1%). There was 1 case in which from the laparoscopic approach to laparotomy (1.9%) was required. The operation time treated by the laparoscopic approach was significantly longer than the open approach (126.4 minutes versus 104.6 minutes; P  = .0079); however, the incidence of postoperative complications and the postoperative length of hospitalization were also less in the former group than in the latter group (3.9% versus 18.5%; P  = .0172 and 5.6 days versus 14.7 days; P  = .0096). Second-stage TAPP herniorrhaphy was performed in 7 patients (15.2%) after bowel resection or closure of bowel perforation, and first-stage TEP herniorrhaphy was performed in 1 patient after bowel resection. There was no case of mesh infection in the group treated by the laparoscopic approach, and there was 1 case of mesh infection in the group treated by the open approach. The mortality rate was 0% in the group treated by the laparoscopic approach. Conclusions: Laparoscopic reduction and herniorrhaphy for acutely incarcerated/strangulated groin and obturator hernias is effective, safe, and feasible.
