Laparoscopic approach to recurrent incisional hernia repair: a 3-year experience.

Background: Incisional hernias are one of the most frequent complications of open abdominal surgery. The incidence of relapses after a conventional repair procedure is higher in recurrent than in primary cases (30%-50% vs. 11%-20%). The laparoscopic approach can prevent the complications associated with the conventional approach when dealing with recurrent incisional hernias. The aim of this study was to evaluate the efficacy of laparoscopic treatment in such cases.

Materials And Methods: We prospectively analyzed data from 41 consecutive patients with recurrent incisional hernias, who submitted to a laparoscopic repair procedure with an expanded polytetrafluoroethylene Dual Mesh (Gore-Tex Dual Mesh Plus Biomaterial; W.L. Gore 8 Associates) from December 2001 to December 2004. All of the patients underwent clinical follow-up at 1, 6, and 12 months and then yearly. An ultrasound scan of the abdominal wall was performed at 6 and 12 months after the procedure. The parameters considered for the analysis were: mesh size, operating time, hospital stay, postoperative complications, and recurrences.

Results: The defects were usually localized along midline laparotomies. The mean mesh size was 400 cm2, the mean operating time was 68 minutes, and the mean length of hospital stay was 2.7 days. Complications were encountered in 17% of patients. The mean follow-up was 38 months (range, 18-54). Recurrence was reported in 1 case only (2.4%), which occurred within the first 6 months after the operation.

Conclusions: The laparoscopic repair of recurrent incisional hernia seems to be an effective alternative to the conventional approach, as it can give lower recurrence and complication rates.
