title: [Clinical evolution of hemorrhage in the proximal portion of the digestive tract. Comparison of its management with and without endoscopy].
abstract: To determine if endoscopic study of the esophago-gastro-duodenal portion of the digestive tract diminishes morbimortality of patients with hemorrhage in this area, a comparative study was made. The results for the first group were obtained from 92 cases of patients with hemorrhage in which endoscopic studies were performed. The results for the second group were obtained from 88 cases of patients with hemorrhage in which no endoscopic study was made. Both groups were comparable in age, sex, magnitude of bleeding and medical management; even though there were more patients in the second group that did not require blood transfusions. No statistically significant differences were found in the number mortality. Diagnostic centainty was higher in the endoscopic group (82.6% versus 36.3% P less than 0.002). The number of the patients released without diagnosis was higher in the group not undergoing endoscopic examination (23.4% versus 8.5% P less than 0.005). The conclusion that endoscopic examination improves the quality of diagnosis in patients with upper digestive tract hemorrhage, but does not diminish morbimortality, is reached. The possible reasons for this are discussed.
