Laparoscopic extraperitoneal inguinal hernia repair.

We have devised a reproducible approach to the preperitoneal space for laparoscopic repair of inguinal hernias that is based on an understanding of the abdominal wall anatomy. Laparoscopic totally extraperitoneal herniorrhaphy was performed on 99 hernias in 90 patients at the Los Angeles County–University of Southern California Medical Center, using a standardized approach to the preperitoneal space. Operative times, morbidity, and recurrence rates were recorded prospectively. The median operative time was 37 min (range, 28–60) for unilateral hernias and 46 min (range, 35–73) for bilateral hernias. There were no conversions to open repair, and there was only one conversion to a laparoscopic transabdominal approach. Complications were limited to urinary retention in two patients, pneumoscrotum in one patient, and postoperative pain requiring a large dose of analgesics in one patient. All patients were discharged within 23 h. There were no recurrences or neuralgias on follow-up at 2 years. A standardized approach to the preperitoneal space based on a thorough understanding of the abdominal wall anatomy is essential to a satisfactory outcome in hernia repair. [ABSTRACT FROM AUTHOR]
