    Change in glucose metabolism after bariatric operations may be credited to duodenal bypass. This study aims to evaluate the effect of duodenal bypass on glucose levels in lean individuals submitted to gastrectomy for gastric cancer. We reviewed 56 non-diabetic and 6 diabetic patients submitted to gastrectomy and Roux-en-Y for gastric cancer (partial gastrectomy in 66%/total gastrectomy in 34%). Glucose levels were not significantly altered after operation (P = 0.5). Diabetes control was improved in one patient with oral medication. In conclusion, duodenal bypass do not decrease glucose levels in lean individuals treated for gastric cancer.

    Esvaziamento gástrico e jejunal proximal em ratos submetidos ou não à gastrectomia parcial com reconstrução do trânsito intestinal em Y de Roux ou a Billroth II

    The aim of this study was to determine the effects of ROUX-EN-Y or BILLROTH II gastrojejunostomy in gastric and proximal jejunal emptying of nutrient liquid meal. Four groups of ten WISTAR rats were used: sham {group I), antrectomy and ROUX-EN-Y gastrojejunostomy (group II), subtotal gastrectomy and ROUX-EN-Y gastrojejunostomy (group III) and antrectomy and BILLROTH II gastrojejunostomy (group IV). The gastric and proxima! jejunal emptying were measured one week after surgery, 60 minutes after gastric introduetion of 1 ml of 99mTc labeled uncooked scrainbled egg. Afler this interval the stomach, proximal intestine, small bowell remaining and colon of each rat were excised and placed in separate containers. The absolute amounts of the radionuclide present in each segment was determined in an ionization camera. The relative amounts was calculated and compared. The gastric emplying Ín ROUX-EN-Y antrectomy group was faster than sham group and slower than ROUX-EN-Y subtotal gastrectomy group (∞ < 0,05), but didn't present a significant difference in relation to antrectomy BILLROTH II group. The ROUX limb emptying (groups II and III) was not significantly different than efferent loop (group IV). !t was concluded that the gastric emptying of nutrient liquid was similar in ROUX-EN-Y and BILLROTH II antrectomy and that in ROUX-EN-Y reconstruction the gastric emptying was faster in subtotal gastrectomy than antrectomy.
