A new technique of laparoscopic obturator hernia repair: report of a case

An 84-year-old woman presented with ileus. Ultrasonography, a computed tomography scan, and small bowel contrast examination showed a Richter-type hernia in her left obturator orifice. Under general anesthesia, laparoscopic surgery with low-pressure (4mmHg) pneumoperitoneum was carried out using a peritoneal needle retractor, and a reduction of the strangulated intestinal loop was thus achieved. Because the hernial opening measured 5mm in diameter, it could be closed with four pieces of End-Universal stapler without polypropylene mesh. The ischemic ileum was resected, and the bowel was anastomosed extracorporeally with a minimal skin incision. She was ambulant on the first postoperative day, and her postoperative course was good. Obturator hernias are rare, but when a definitive diagnosis is made in such elderly patients, laparoscopic repair using the peritoneal needle retractor is recommended for minimally invasive surgery. We recommend doing the repair with an End-Universal stapler, since this procedure is more simple and useful for preventing infection than using polypropylene mesh in such a strangulated case.
