title: Is laparoscopic treatment of incisional and recurrent hernias associated with an increased risk for complications?
abstract: BACKGROUND
  Hernias of the ventral abdominal wall can be treated with an intraperitoneal onlay mesh (IPOM). The aim of this cohort study was to analyze the complications and recurrence rates after laparoscopic ventral hernia repair focusing especially on incisional and recurrent hernias.
  
  
  METHODS
  The study population comprised 149 patients with a hernia of the abdominal wall, which was treated with an IPOM between January 2006 and January 2011.
  
  
  RESULTS
  Fifty-one patients had a primary hernia (group I) and 98 patients had preceding abdominal surgery (group II). In group II 64 patients had an incisional hernia and 34 patients had a recurrent hernia. The median body mass index was 30.3 kg/m(2) (14.8-69.1) without any significance in sub-group comparison. The mean duration of surgery and the length of stay were significantly longer in group II (p < 0.05). The overall rate of minor complications was 18.1%. There were significantly more minor complications in group II (7.8% vs. 23.5%, p = 0.02). Notably, there were also significantly more major complications in group II (14.3% vs. 2.0%; p = 0.02). The recurrence rate was significantly higher in group II (group I: 3.9% vs. group II: 16.3%, p < 0.05). There were no early recurrences in group I, but 5 early recurrences in group II.
  
  
  CONCLUSIONS
  Laparoscopic treatment of complex hernias as incisional hernias, recurrent hernias and hernias with interenteric and enteroperitoneal adhesions is associated with high rates of minor and major complications. A high level of expertise of the surgeon and the camera-guiding assistant is therefore needed.
