The outcome after Roux-en-Y gastric bypass (RYGBP) in morbidly obese (MO) (body mass index [BMI] 40-50) was compared with super-obese (SO) (BMI >50) and super-super-obese (SSO) (BMI >60) patients. A prospective study was conducted in 738 consecutive patients who underwent RYGBP. 483 MO were compared with 184 SO and 70 SSO. Study endpoints included: effect on co-morbid conditions, postoperative morbidity and mortality, and long-term results. Statistical analysis utilized SPSS 11.0. Percentage of males was significantly greater in the SO groups (16.5% vs 13%, P=0.01). Obesity-related conditions were significantly more frequent in the SO groups: sleep apnea (38% vs 17%, P50% at 5 years was: MO 81.5%, SO 87.5%, SSO 80%. The surgery was effective in treating the co-morbid conditions. RYGBP achieved significant durable weight loss and effectively treated co-morbid conditions in SO and SSO patients with acceptable postoperative morbidity and slightly greater mortality than in MO patients.
