title: Laparoscopic incisional hernia mesh repair with the "double-crown" technique: a case-control study.
abstract: BACKGROUND
  Incisional hernia is a main complication of abdominal surgery. Laparoscopic hernia mesh repair has been demonstrated to be as effective as open repair. However, the mesh fixation method is, to date, a matter of debate, and there are few clinical studies evaluating a single technique. This was a case-control study to assess the "double-crown" fixation method.
  
  
  METHODS
  From March 2000 to November 2005, we prospectively collected operative and outcome data on 94 laparoscopic mesh repairs of large incisional hernias performed by using the double-crown technique. The data were compared with those from a retrospective review of 87 matched open incisional hernia repairs done from January 1995 to January 2000.
  
  
  RESULTS
  The open and laparoscopic repair groups were comparable in patient age, sex, and hernia size. Operative time was significantly longer in the laparoscopic group; the duration of hospitalization and number of early postoperative complications (e.g., wound infection and prolonged ileus) were significantly greater in the open group. Recurrence rate after a mean follow-up of 38 months (range, 12-72) was 2.1% in the laparoscopic group and 6.9% in the open repair group (mean follow-up, 8 years; range, 5-10) (P > 0.05).
  
  
  CONCLUSIONS
  Medium-term results indicate that laparoscopic incisional hernia repair with the double-crown technique has a low complication rate and a comparable recurrence rate to open repair.
