Medico-legal claims in bariatric surgery in France between 2010 and 2015.

The practice of bariatric surgery has multiplied 3.5 times in France in the last ten years. The purpose of the study is to analyze medico-legal claims in this area in order to identify lessons to improve patient care.Two visceral surgeons analyzed 358 independent claim files. Age, gender, socio-economic origin, body mass index, surgical history, depression, smoking, anticoagulants, and pre-operative assessment of patients were recorded. The operative indication, the type and date of occurrence of the event, the existence and causes of intra-operative incidents, re-interventions, inter-hospital transfers and deaths were noted. Any anomaly of care, whether noted by the expert or the court, was considered a fault.The types of bariatric procedures included sleeve gastrectomy in 52.1% of cases and gastric bypass in 33.2% of cases. A third of patients (31.2%) had a history of previous abdominal surgery. The main complications were anastomotic leak (48.6%), followed by vomiting, wounds of neighboring organs, and infections. Fault was found in 30.4% of cases: for delay of care (36.8%), surgical clumsiness or ineptitude (15.5%), incorrect indications, lack of patient information. In 6.4% of cases, metabolic deficiencies with encephalopathy developed.The indications of the French High Authority of Health [Haute autorité de santé (HAS)] must be respected and intra-operative difficulties should not be underestimated in patients who have undergone previous surgery. Post-operatively, clinical signs of severity take precedence over complementary examinations, even when negative. Close monitoring is necessary to quickly detect complications that occur outside the facility, whether it is a surgical complication or vitamin deficiency.
