Laparoscopic repair is a treatment of choice for selected patients with incarcerated obturator hernia.

purposeThe feasibility and potential advantages of laparoscopic diagnosis and repair of incarcerated obturator hernia (OH) is debated. The aim of this retrospective study was to compare short-term complications comparing laparoscopic to open repair of OH.

methodsA total of 29 preoperatively diagnosed patients underwent surgery for a preoperatively diagnosed OH between January 2006 and July 2017. The patients were divided into a laparoscopic group (11 patients underwent laparoscopic repair; 8 without and 3 with intestinal resection) and an open group (18 patients who underwent open repair; 9 without and 9 with intestinal resection).The outcomes were compared between groups. A risk factor analysis for postoperative complications was performed.

resultsThe incidence of postoperative complications was fewer in the laparoscopic group [9.0% vs. 61.1%; (p < 0.001)]. The bleeding amount [1.2 g vs. 40.4 g; (p = 0.087)] and postoperative length of stay [13.3 days vs. 17.1 days; (p = 0.072)] showed a tendency to be favorable in the laparoscopic group. Occult contralateral OH was detected in three patients (27.7%) in the laparoscopic group and one patient (5.5%) in the open group (p = 0.099). Open surgery and intestinal resection were independent risk factors for a postoperative complication. One patient in the open group developed an incarcerated OH on the contralateral side 1 year after the first surgery.

conclusionsLaparoscopic repair for incarcerated obturator hernia demonstrated more favorable short-term outcomes compared with open repair in terms of a lower incidence of postoperative complications and it was potentially beneficial for detecting and repairing an occult OH on the contralateral side.
