Bariatric surgery in mainland China is still in its initial stages. The aim of this study was to investigate the feasibility and efficacy of laparoscopic Roux-en-Y gastric bypass (LRYGB) for Chinese super obese patients with body mass index (BMI) ≥60 kg/m.


Twenty-six super obese patients underwent LRYGB, performed by a single surgeon, at the First Affiliated Hospital of Jinan University between June 2004 and September 2012. Surgical outcomes were analyzed retrospectively.


All 26 LRYGB procedures were performed successfully, with no conversion to open surgery. Preoperative mean body weight and BMI were 192.3 kg and 65.8 kg/m, respectively. Mean percentage of excess weight loss in the 12 months after surgery was 55.3±7.6%. Obesity-related comorbidities improved significantly. Two patients experienced perioperative complications, 1 with respiratory failure and 1 with umbilical wound infection. Six patients developed long-term complications, but all were cured by conservative treatment.


Chinese obese population is unique in diet, lifestyle, sex, age, and geographical differences. LRYGB is feasible for Chinese super obese patients, with significant short-term results. Further observations are required to assess long-term outcomes.
