Medico-legal analysis of legal complaints in bariatric surgery: a 15-year retrospective study.

BACKGROUND: Bariatric surgery for severe obesity has become an effective and accepted treatment for sustained weight loss.

OBJECTIVES: The aim of our study was to analyze the complications and issues raised by the experts on which jury or judges' decisions were made for the different types of bariatric surgery.

SETTING: University Hospital, France.

MATERIALS AND METHODS: We have carried out a retrospective study of 59 expert review dossiers over a period of 15 years (1999-2014) on the different types of bariatric surgery (laparoscopic adjustable gastric band [LAGB], sleeve gastrectomy [SG], Roux-en-Y gastric bypass [RYGB], vertical banded gastroplasty [VBG], and gastric plication [GP]).

RESULTS: Of the cases, 81% were women and the average age was 39 years old (range 19 to 68 years). Among the procedures giving rise to the complaints, 40% were for LAGB, 28% for RYGB, and 23% for SG. The most common initial complications were perforations (30%), fistulae (27%), bowel obstruction (14%), vascular injuries (9.5%), and infections (peritonitis, pleurisy, abscesses, and so forth) (8%). Revision surgery was required in 78% of patients, and perioperative complications accounted for 28.5% of dossiers. The experts concluded that fault had occurred in 40% of case. Negligence arising from an error deemed to be an act of negligence was found in 30% of cases, 67% of which were because of delayed diagnosis. Major long-term complications accounted for 8% of dossiers and minor long-term complications for 22%. Forty-seven percent of patients completely recovered.

CONCLUSION: Delayed diagnosis was the main error established by the experts. Surgeons should remain vigilant postoperatively after every bariatric surgical procedure.
