Robot-assisted single-anastomosis duodeno-ileal bypass with sleeve gastrectomy / 中华胃肠外科杂志

ABSTRACT

Single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) is simpler and has similar efficacy for obesity and obesity-associated metabolic diseases in comparison to biliopancreatic diversion with duodenal switch. We reported the first Da Vinci robot-assisted SADI-S in the treatment of severe obesity in China. This male patient was 27-year-old with height of 180 cm, body weight of 140 kg, waistline of 125 cm and body mass index of 43.2 kg/m(2). The diagnosis at admission was fatty liver, severe obesity, hypertriglyceridemia and hyperuricemia. The patient underwent Da Vinci robot-assisted SADI-S. The surgeon identified ileocecal part by appendix, then a common channel was measured retrogradely from the ileocecal valve, the distal ileum at 300 cm from the ileocecal part was marked and suspended. A sleeve gastrectomy was performed over a 34 Fr bougie tube. An end-to-side anastomosis between proximal duodenum and the pre-marked ileum was performed after duodenal bulb transection. Gastric incision was sutured with omentum reinforcement. No leakage was found after injecting methylene per os. Finally, a drainage tube was left in place under the anastomosis and close to the duodenal stump. The operation time was 244 minutes and the amount of bleeding during surgery was 50 ml. The patient recovered well with a postoperative hospital stay of 7 days and was followed up for six months. The percent of excess weight loss (EWL%) was 80.21% at 6 months after operation. The body weight, body mass index and waist circumference decreased significantly after operation. Complete remission was achieved for hypertriglyceridemia, hyperuricemia and insulin resistance. The patient suffered from cholestasis without serious complications at 6 months after operation. Our experience shows that Da Vinci robot-assisted SADI-S is safe and feasible in treating severe obesity.
