Local and general anesthesia in the laparoscopic preperitoneal hernia repair.

OBJECTIVE: The extraperitoneal laparoscopic approach (EXTRA) has been shown to be an effective and safe repair for primary (PIH), recurrent (RIH) and bilateral hernia (BIH). There is very little data examining the merits of laparoscopic repair for hernias under local anesthesia. In this' paper, we compare EXTRA performed under both general and local anesthesia. METHODS: This nonrandomized prospective study was performed selectively on a male population only. Patients with associated pulmonary disease and high risk for general surgery were selected. Patients with recurrence and previous abdominal operations were excluded to decrease confounding variables in the study. A Prolene mesh was used in all patients. RESULTS: Between May 1997 and September 1998, 92 male patients underwent the repair of 107 groin hernias using the EXTRA technique. The procedure was explained to them, and different anesthesia options were given. Fourteen of these repairs were performed under local anesthesia and 93 under general anesthesia. Of the 10 patients who underwent a repair under local anesthesia, there were 8 indirect, 5 direct and 1 pantaloon. The mean age was 53 years. In the group of general anesthesia, the types of hernias repaired were 45 indirect, 30 direct and 11 pantaloon. The mean age was 45 years. The mean follow-up was 15 months. Each patient was sent home the same day. Two peritoneal tears were recorded in the first group. The operative time was longer in the local group (47 +/- 11 vs 18 +/- 3). None of the patients required conversion to an open technique or change of anesthesia. No recurrences were found in either group. The average time of return to work and regular activity was 3.5 +/- 1 and 3 +/- 1 days, respectively. CONCLUSION: There appears to be no significant difference in recurrence and complication rates when the EXTRA is performed under local anesthesia as compared to general. Blunt dissection of the preperitoneal space does not trigger pain and does not require lidocaine injection. The most painful area is the peritoneal reflection over the cord structure. The laparoscopic repair under local anesthesia represents an advantage in the repair of the inguinal hernia, particularly in the population where general anesthesia is contraindicated.
