title: Outcome of laparoscopic ventral hernia repair in correlation with obesity, type of hernia, and hernia size.
abstract: BACKGROUND
  The morbidity and overall recovery time of ventral hernia repair can vary significantly depending on the hernia type or size and on other factors, such as the body mass index (BMI). The purpose of our study was to investigate the effects of type of hernia, hernia size, and BMI on the outcome of laparoscopic ventral hernia repair.
  
  
  METHODS
  Fifty patients who underwent laparoscopic ventral hernia repair were retrospectively reviewed and stratified according to hernia type (incisional, IVH/primary, PVH), hernia size, and BMI. These subgroups were compared in regard to operative time, resumption of diet, hospital stay, pain control, and complication rate.
  
  
  RESULTS
  Laparoscopic IVH repair was associated with a longer operative time (143 vs. 98 minutes, p = .02) and length of stay (2.2 vs. 0.6 days, p = .03) than PVH repair. The narcotic requirements were higher in the IVH group, but the difference did not reach statistical significance. Larger hernias were associated with a longer operative time (p = .04) and increased narcotic requirement (p = .03). The morbidity of the laparoscopic repair was not significantly affected by the hernia type or size. The BMI did not significantly alter any of the parameters examined.
  
  
  CONCLUSIONS
  Laparoscopic repair of incisional and larger hernias is a technically demanding procedure that requires a longer operative time. In contrast to PVH repair, laparoscopic IVH repair usually cannot be performed on an outpatient basis. Surgeons need not be discouraged from recommending the laparoscopic approach for patients with large IVHs or with severe obesity because the morbidity remains low.
