Laparoscopic repair of large incisional hernias.

Conventional repair of large incisional hernias is often associated with a painful postoperative recovery and a delayed return to normal activities. We describe here a technique of laparoscopic incisional hernia repair and review our experience with 30 cases. Hernias ranging in size from 10 to 420 cm2 (mean, 104 cm2) were repaired using a polytetrafluoroethylene patch (16 cases) and a Prolene mesh (14 cases). Operating room time ranged from 45 mins to 190 min (mean 108 mins). Postop stay ranged from 1 to 17 days (mean, 4.3 days; median, 3 days). Follow-up extends beyond 18 months. Postoperative complications included ileus (three cases) trocar site infection (one case) and urinary retention (two cases). There has been one hernia recurrence to date. Our experience with the laparoscopic repair of incisional hernias reveals it to be technically feasible with minimal morbidity, allowing patients prompt resumption of regular activities. Prospective comparison with conventional repair and longer follow-up are needed.
