SummaryIn this study, laparoscopic transabdominal preperitoneal inguinal hernia repair and traditional open inguinal hernia repair were compared in relation to operative time, hospital stay, pain medication use, recovery time, complications, and costs. Elective hernia repairs, 126 in 106 patients, were prospectively followed from January 1991 through September 1993. Seventy-five procedures were performed by laparoscopy and 51 by traditional open approach. Time off work, pain medication use, surgical complications, and hospital stay were all significantly less (p< 0.001) with the laparoscopic approach. Patients in the laparoscopic group returned to work on average 5.5 weeks earlier than patients who underwent traditional herniorrhaphy. The difference in operative times was not statistically significant; however, the difference in the cost of the operations was. In conclusion, laparoscopic inguinal hernia repair offers significantly decreased postoperative pain, shorter hospital stays, faster return to work, fewer complications, and comparable operative times, but at an increased expense for the cost of laparoscopic instrumentation and technology.
