A randomized controlled trial of laparoscopic extraperitoneal hernia repair as a day surgical procedure

Abstract

Background: A randomized controlled trial was conducted in a day surgery setting comparing a standardized variant of the Shouldice hernioplasty with extraperitoneal laparoscopic herniorrhaphy.

Methods: The laparoscopic repair was technically challenging, evidenced by conversion from extraperitoneal to transabdominal repairs in 6.25% of patients. It was free from the inherent dangers of intraperitoneal laparoscopy. Surgical morbidity was low and comparable to that for patients randomized to the open repair.

Results: Outcome following laparoscopic extraperitoneal herniorrhaphy varied depending on the parameter measured. It was comparable to the open repair with respect to postoperative activity levels and the number of days required for return to work but inferior to the open repair in terms of operation time and time to hospital discharge. The extraperitoneal approach was superior to the open repair with respect to postoperative pain levels and analgesic requirements. No attempt was made to compare recurrence rates due to the short follow-up period.

Conclusions: Laparoscopic extraperitoneal herniorrhaphy should not supercede conventional hernia repair until subjected to further trials with the aid of larger study populations and greater technical expertise; the results of long-term recurrence rates are awaited.
