Simultaneous repair of bilateral inguinal hernias: a prospective, randomized study of open, tension-free versus laparoscopic approach

No randomized trial exists that specifically addresses the issue of laparoscopic bilateral inguinal hernia repair. The purpose of the present prospective, randomized, controlled, clinical study was to assess short- and long-term results when comparing simultaneous bilateral hernia repair by an open, tension-free anterior approach with laparoscopic "bikini mesh" posterior repair. Forty-three low-risk male patients with bilateral primary inguinal hernia were randomly assigned to undergo either laparoscopic preperitoneal "bikini mesh" hernia repair (TAPP) or open Lichtenstein hernioplasty. There was no difference in operating time between the two groups. The mean cost of laparoscopic hernioplasty was higher (P < 0.001). The intensity of postoperative pain was greater in the open hernia repair group at 24 hours, 48 hours, and 7 days after surgery (P < 0.001), with a greater consumption of pain medication among these patients (P < 0.05). The median time to return to work was 30 days for the open hernia repair group and 16 days for the laparoscopic "bikini mesh" repair group (P < 0.05). Only 1 asymptomatic recurrence (4.3%) was discovered in the open group. The laparoscopic approach to bilateral hernia with "bikini mesh" appears to be preferable to the open Lichtenstein tension-free hernioplasty in terms of the postoperative quality of life and interruption of occupational activity.

Hernioplasty and simultaneous laparoscopic cholecystectomy: a prospective randomized study of open tension-free versus laparoscopic inguinal hernia repair

BACKGROUND

The laparoscopic repair of unilateral primary groin hernia remains controversial. This randomized study evaluates the outcome of the laparoscopic technique in hernia repair in patients undergoing simultaneous laparoscopic cholecystectomy (LC) and compares laparoscopic repair with tension-free open groin hernia repair.

METHODS

Sixty-four low-risk patients with symptomatic chronic calculous cholecystitis and synchronous unilateral primary inguinal hernia were randomized to undergo either laparoscopic transabdominal preperitoneal mesh hernia repair (TAPP) and LC or LC and open tension-free hernia repair.

RESULTS

The operating time was longer in the TAPP and LC group (mean +/- SD = 121 +/- 32 minutes) than in the LC and open group (95 +/- 27 minutes) (P <.01). The mean operating costs were higher in the TAPP and LC group ($1235 versus $1080) (P <.03). The intensity of postoperative pain at rest was greater in the LC and open group at 24 hours (P <.01) and 48 hours (P <.05), with a greater consumption of pain medication (P <.01). No differences between the 2 groups were found in terms of postoperative complications, disability period before return to work, or hernia recurrences.

CONCLUSIONS

The totally laparoscopic procedure does not result in a significant benefit other than improved comfort in the first 2 postoperative days. However, laparoscopic hernia repair is considerably more difficult to perform than open tension-free hernioplasty. Thus, the totally laparoscopic approach should be performed only by experienced laparoscopic surgeons with special expertise in hernia surgery.
