Abstract

Background

Over the past 14 years, we have used different malabsorptive bariatric operations to treat super-obesity. We compared the efficacy and safety of our preferred procedure for the last 8 years with previous methods used in super-obese.

Methods

Our first procedure was distal Roux-en-Y gastric bypass (distal RYGBP) (gastric pouch 15 ± 5 mL, 80 cm biliopancreatic limb, 100 cm common limb [CL]). The second was distal RYGBP with short alimentary limb (distal RYGBP-sAL) (gastric pouch 15 ± 10 mL, alimentary limb [AL] 250 cm, CL 100 cm). Our preferred procedure for the past 8 years has been biliopancreatic diversion with RYGB and long limbs (BPD-RYGB-LL) (gastric pouch 40 ± 10 mL, AL 400 cm, CL 100 cm).

Results

Seventy-five patients underwent distal RYGBP, 44 distal RYGBP-sAL, and 841 BPD-RYGB-LL. Eight years postoperatively, the mean BMIs were 39.0, 29.4, and 29.2, respectively. The greatest reduction of 47.6% was achieved with BPD-RYGB-LL (distal RYGBP 30.6%; distal RYGBP-sAL 43.1%). Mean excess weight loss was 51.3% for distal RYGBP, 76.5% for distal RYGBP-sAL, and 80.9% for BPD-RYGB-LL. Six patients died at the early postoperative period. Sixteen patients died during the first eight postoperative years, of whom significantly more were after distal RYGBP-sAL (P = 0.0003). Complications were significantly more frequent after distal RYGBP-sAL (P = 0.001). All procedures led to rapid and sustained resolution of major comorbidities in almost all patients affected. Metabolic and nutritional deficiencies were similar and manageable.

Conclusions

Our variant of biliopancreatic diversion (BPD-RYGB-LL) results in substantial and sustained weight loss in super-obese, without compromising safety.
