title: Laparoscopic repair of incisional and parastomal hernias after major genitourinary or abdominal surgery.
abstract: OBJECTIVE
  Abdominal wall or parastomal hernias following major genitourinary or abdominal surgery are a significant surgical problem. Open surgical repair is difficult because of adhesion formation and poor definition of the hernia fascial edges. Laparoscopic intervention has allowed effective correction of these abdominal wall hernias.
  
  
  METHODS
  From November 1997 to June 2000, 14 male and 3 female patients underwent laparoscopic abdominal wall herniorrhaphy at our institution. Of these, 13 patients received incisional and 4 parastomal hernia repair. All hernia defects were repaired using a measured piece of Gore-Tex DualMesh. A retrospective review of each patient's history and operative characteristics was undertaken.
  
  
  RESULTS
  All repairs were successful. No patient required conversion to an open procedure, and there were no intraoperative complications. The average operative time was 4 (range 2.5-6.5) and 4.3 (range 3.75-5.5) hours in the incisional and parastomal group, respectively. The average hospital stay was 4.9 days (range 2-12) for the incisional group and 3.8 (range 3-4) days for the parastomal group. To date, two patients experienced a recurrence of incisional hernias, at 5 and 8 months postoperatively. No recurrences have developed in the parastomal hernia repairs at 2 to 33 months.
  
  
  CONCLUSIONS
  Laparoscopic repair of abdominal wall incisional or parastomal hernias provides an excellent anatomic correction of such defects. Adhesions are lysed under magnified laparoscopic vision, and the true limits of the fascial defects are clearly identified. The DualMesh is easy to work with and has yielded excellent results. A comparison with open repair with respect to perioperative factors and long-term success is currently under way.
