[The relations between the morphology of the postresection gastric stump after a gastroduodenal ulcer and the dumping syndrome]. / Relatii între morfologia bontului gastric post rezectie dupa ulcerul gastroduodenal si sindromul "dumping".

Of a group of 272 patients subjected to gastric resection for gastric-duodenal ulcer, the "dumping" syndrome was found in 46 (17%). The most frequent (39.7%) was in the Reichel-Polya anastomosis type and the less frequent (9%) in pyloroplasties. The test of induced hyperglycemia by ingesting 15 g/kg body glucose did not show differences in the values of the maximum glycemia in the patients with the "dumping" syndrome versus the other group. The surface of the anastomosis opening and the length of the gastric stump were appreciated with a central imaging endoscope. The surface of the anastomosis opening was found larger in those with a "dumping" syndrome and Reichel-Polya's resection, although the differences are not statistically significant; likewise, there seems to be a less length of the gastric stump and a higher weight difference in those with the "dumping" syndrome. The lack of pyloric sphincter seems to be very important in producing the "dumping" syndrome due to the fact that the alimentary bolus is not fractionated and its sequential evacuation in duodenum and jejunum does not take place.
