Is Roux-en-Y gastric bypass adequate in the super-obese?
Obes Surg 2006; 16(4):478-83OS

Abstract

BACKGROUND

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.

METHODS

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.

RESULTS

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%, P<0.0005), gallstones (23% vs 14%, P=0.013); diabetes (29% vs 17%, P=0.002). Hospital stay was longer in the SO groups (5.7+/-6.1 days vs 4.6+/-2.6 days, P=0.024). Wound infection was more frequent in the SO groups (4.7% vs 1.4%, P=0.019). Postoperative mortality was greater in the SSO and SO groups (1.6% and 1.4%) than MO (0%) (P=0.019). Incisional hernia was more frequent in the SO groups (14.1% vs 8.6%; P=0.041). There was no significant difference in percent of excess weight loss (%EWL) between the three groups. EWL >50% at 5 years was: MO 81.5%, SO 87.5%, SSO 80%. The surgery was effective in treating the co-morbid conditions.

CONCLUSION

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.
