COMPARISON OF CONVENTIONAL ANTERIOR SURGERY AND LAPAROSCOPIC SURGERY FOR INGUINAL-HERNIA REPAIR

Background Inguinal hernias can be repaired by laparoscopic techniques , which have had better results than open surgery in several small stu dies. Methods We performed a randomized, multicenter trial in which 48 7 patients with inguinal hernias were treated by extraperitoneal lapar oscopic repair and 507 patients were treated by conventional anterior repair. We recorded information about postoperative recovery and compl ications and examined the patients for recurrences one and six weeks, six months, and one and two years after surgery. Results Six patients in the open-surgery group but none in the laparoscopic-surgery group h ad wound abscesses (P=0.03), and the patients in the laparoscopic-surg ery group had a more rapid recovery (median time to the resumption of normal daily activity, 6 vs. 10 days; time to the return to work, 14 v s. 21 days; and time to the resumption of athletic activities, 24 vs. 36 days; P<0.001 for all comparisons). With a median follow-up of 607 days, 31 patients (6 percent) in the open-surgery group had recurrence s, as compared with 17 patients (3 percent) in the laparoscopic-surger y group (P=0.05). All but three of the recurrences in the latter group were within one year after surgery and were caused by surgeon-related errors. In the open-surgery group, 15 patients had recurrences during the first year, and 16 during the second year. Follow-up was complete for 97 percent of the patients. Conclusions Patients with inguinal he rnias who undergo laparoscopic repair recover more rapidly and have fe wer recurrences than those who undergo open surgical repair.
