Bariatric Surgery is currently the best treatment option for patients with Morbid Obesity and a Body Mass Index ≥ 40 kg/m2. Despite its high rate of postoperative and nutritional complications, biliopancreatic diversion (Scopinaro s procedure) has shown best results in terms of excess weight loss and improving obesity-associated diseases. This technique was performed on a 52-year-old woman (weight = 174 Kg, height = 152 cm, BMI= 75.3 kg/m2), with a classic open access due to anaesthesiologist's indication. During this procedure it was also performed a resection of a giant fatty mass on the inner side of left lower limb, which was ulcerated and infected. Postoperative period was uneventful, excepting wound dehiscence of the leg, requiring re-suturing. Six months after hospital discharge, the patient's percent excess weight loss was 36.98%. In our bariatric surgery series, with more than 400 patients since 2002, this patient was the one with the highest BMI.
