title: Surgery-related complications of ventral hernia reported to the Finnish Patient Insurance Centre.
abstract: OBJECTIVE
  Our aim was to evaluate the incidence and type of severe complications in adult primary and incisional ventral hernia surgery reported to the National Patient Insurance Centre in Finland during 2003-2010.
  
  
  METHODS
  The Finnish National Patient Insurance Centre covers the whole country and handles financial compensation for patients' injuries without proof of malpractice. All the claims concerning ventral hernioplasties in the Centre between the years 2003 and 2010 were retrospectively analyzed. The annual numbers of primary and incisional ventral hernioplasties in Finland were obtained from the National Hospital Discharge Register.
  
  
  RESULTS
  During the study years, 25,738 ventral hernia operations were performed and 127 claims from the whole country were reported to the Patient Insurance Centre. Overall rate of claims was 4.9/1000 hernia procedures. For primary hernias, 16,243 ventral hernioplasties (817 laparoscopic, 15,426 open) were performed and 41 complications were reported. The most common complication was infection (n = 28, 68%) followed by pain and hernia recurrence (n = 6, 15% in both), large hematoma (7%), bowel lesion (5%), urological injuries (2%), or severe bleeding (2%). In incisional hernioplasties, the rate of claims was 9.1/1000 operations (9495 operations, 86 claims). The most common complication reported was infection (n = 42, 49%) followed by hernia recurrence in 25 cases (29%) and bowel lesion in 24 cases (28%). Major complications (n = 15, 17%) consisted mainly of bowel lesions in laparoscopic operations. There was significantly more claims after laparoscopic than open hernioplasties (p = 0.001).
  
  
  CONCLUSIONS
  The claims for financial compensation for injuries related to primary and incisional hernioplasties are quite uncommon. Major complications, though comparatively rare, are significantly more common after laparoscopic operations.
