Background
In an effort to reduce the complications of Scopinaro’s biliopancreatic diversion (BPD), in 1989 we introduced the modification of lengthening the alimentary channel preserving most of the jejunum-ileum, by creating a short biliopancreatic limb (50 cm) and maintaining 50 cm of common limb (Larrad 50–50 BPD).
Methods
Of 343 patients who consecutively underwent Larrad 50–50 BPD surgery, 325, 194 and 65 patients were evaluated at 2, 5 and 10years after surgery, respectively, in terms of surgical morbidity, mortality, metabolic sequelae and weight. Mean age was 41.2years (range 17–62), mean initial weight 151.2 kg (range 97–260), and BMI was 52.2 kg/m2. Maximum follow- up was 120months.
Results
Mortality was 0.87% and surgical morbidity 7.6%. There were no cases of suture dehiscence, peritonitis or stomal stenosis. Percent excess weight loss (%EWL) stabilized 2years after surgery and at 10years was 77.8±11.2% for morbidly obese patients and 63.2±11.8% for super-obese patients. The main complications were 43.8% clinical incisional hernia, 2.5% severe diarrhea, 10.8% mild diarrhea and 9.2% constipation. 30% experienced anemia and/or iron deficiency, and 3% required iron parenterally or lifelong zinc supplements. 28% showed preoperative PTH elevation and 30% vitamin D deficiency; these values postoperatively increased to 45% and 43% respectively. Both these alterations were resolved using supplements, although 12% needed increased doses of vitamin D. The incidence of severe hypoproteinemia was 0.29%. No patient required surgical reversal. When independently evaluated, failure rates in terms of insufficient weight loss were 9% at 5years and 11.3% at 10 years for morbidly obese, and 12.2% and 14% for super-obese patients respectively. According to the BAROS questionnaire, 75% of surgery outcomes were excellent or very good, 18% good, 5% fair and 2% failures.
Conclusions
After 2, 5 and 10years, Larrad’s BPD has offered excellent results in terms of weight loss and quality of life, a low rate of metabolic sequelae, including a hypoproteinemia rate <0.5%, and a revision surgery rate 0%.
