Successful software reuse requires the systematic discovery and exploitation of commonality across related software systems. By examining related software systems and the underlying theory of the class of systems they represent, domain analysis can provide a generic description of the requirements of that class of systems and a set of approaches for their(More)
BACKGROUND Patients undergoing either Roux-en-Y gastric bypass (RYGBP) or biliopancreatic diversion (BPD) with RYGBP are at risk of developing metabolic sequelae secondary to malabsorption. We compared the differences in nutritional complications between these two bariatric operations. METHODS A retrospective analysis of a prospective database was done.(More)

BACKGROUND In the non-superobese population, an agreement has not been made as to the optimal bariatric operation. The present study reports the results of a prospective comparison of Roux-en-Y gastric bypass (RYGBP) and a variant of biliopancreatic diversion (BPD) in a non-superobese population. METHODS From a cohort of 130 patients with BMI 35 to 50(More)
OBJECTIVE To investigate the effect of marked weight loss after long limb-biliopancreatic diversion (BPD-LL) on bone mass and serum calcium, 25-OH-vitamin D, and PTH levels in relation to calcium supplementation. BACKGROUND DATA BPD is the most effective type of bariatric surgery, but it is followed by bone mass loss, mainly attributed to calcium and(More)
BACKGROUND This study presents late results of a previously published 2-year prospective comparison between Roux-en-Y gastric bypass (RYGBP) versus biliopancreatic diversion with Roux-en-Y gastric bypass (BPD-RYGBP) in an exclusively non-superobese population. METHODS From a cohort of 130 patients with a BMI of 35-50 kg/m(2), 65 were randomly selected to(More)
