This retrospective study compares the clinical and nutritional outcomes of 100 morbidly obese patients who underwent biliopancreatic diversion (BPD) with common (CC) and alimentary channel (AC) length, respectively, 50/250 and 80/200 cm.
One hundred patients who received BPD from October 2006 to November 2011 were identified from a database of bariatric procedures performed at the University Hospital of Messina, and the outcomes in terms of weight loss and morbidity were compared. Forty morbidly obese patients underwent BPD with CC 80 cm and AC 200 cm (group 1) and 60 morbidly obese patients underwent BPD with CC 50 cm and AC 250 cm (group 2).
A gradual weight loss was observed in both groups during the first 3 years after the operation without any significant difference between the two groups. Two cases of protein malnutrition occurred in the group 2 (3 %) due to poor patient compliance in terms of adequate dietary protein intake. Sideropenic anemia was found in 42 % of obese patients in group 2 versus 22.5 % in group 1 at third-year follow-up despite adequate supplementation (p = 0.047). Diarrhea occurred more frequently with a shorter CC. Lipophilic vitamin deficiencies occurred more frequently with a shorter CC despite adequate oral supplementation.
In the medium term, our series showed that shorter CC was associated with no weight loss advantage but with higher morbidity rate, especially in young and fertile women. We recommend a longer CC (80 cm) to be performed especially in this sub-population of obese patients.
