gastrointestinal bleeding
(redirected from GI bleeding)

   Also found in: Wikipedia 0.01 sec.
gastrointestinal bleeding,
any bleeding from the GI tract. The most common underlying conditions are peptic ulcer, Mallory-Weiss syndrome, esophageal varices, diverticulosis, ulcerative colitis, and carcinoma of the stomach and colon. Vomiting of bright red blood or passage of coffee ground vomitus indicates upper GI bleeding, usually from the esophagus, stomach, or upper duodenum. Aspiration of the gastric contents, lavage, and endoscopy are performed to determine the site and rate of bleeding. Tarry black stools indicate a bleeding source in the upper GI tract; bright red blood from the rectum usually indicates bleeding in the distal colon. GI bleeding is treated as a potential emergency. Patients may require transfusions, fluid replacement, endoscopic treatment, or gastric lavage and are watched carefully so as to prevent shock and hypovolemia. In all patients blood loss is evaluated and ability to coagulate is tested. See also coffee-ground vomitus, hematochezia, melena.

The harm due to the GI bleeding was somehow deemed worth accepting to save the money that the Cox IIs would cost.
They matched 1,321 cases of upper GI bleeding due to erosion, peptic ulcer, or inflammation of the gastric or duodenal mucosa with 10,000 control subjects who had no GI bleeding.
Endoscopy (with biopsy) of the esophageal mucosa is indicated for patients who are unresponsive or refractory to potent antisecretory drug therapy or in those with dysphagia, odynophagia, or GI bleeding, to rule out esophageal cancer; in patients with long-standing GERD, to rule out Barrett''s esophagus; and in patients with atypical symptoms, when the response to empirical therapy is difficult to evaluate.
