Laparoscopic preperitoneal inguinal hernia repair without peritoneal incision. Technique and early clinical results

More than 500,000 hernia procedures are performed annually in the United States alone. The authors have devised a new technique for laparoscopic hernia repair. The peritoneum is not incised, as the space between the abdominal wall and the peritoneum is developed with CO2 and blunt dissection. The trocars and laparoscope are placed within this preperitoneal space. Mesh is stapled to Cooper's ligament and the underside of the abdominal wall. From November 1990 to January 1992, 68 herniae have been repaired in 35 patients. The first 25 patients were kept overnight for observation and discharged the following day. Thirty-two patients (92%) were able to resume full physical activity within 1 week. Average follow-up was only 12 months, but there were no recurrent or retained herniae.
