Prognostic markers in upper gastrointestinal hemorrhage.

This study was undertaken to ascertain whether clinical and endoscopic factors can predict the outcome in patients with acute upper gastrointestinal hemorrhage. A total of 185 patients admitted with hematemesis over a 4-year period were studied. Clinical evidence of shock and hepatocellular dysfunction and hemoglobin level were noted on admission. Endoscopy was performed within 48 hours of admission to look for the site and number of lesions, and stigmata of hemorrhage. On analysis, age, clinical evidence of shock, hepatic dysfunction and hemoglobin less than 8.0 g/dl (80 g/L) were found to be significant in prediction of risk of further hemorrhage. Similarly age, past history of jaundice, previous bleeding episodes and clinical evidence of hepatic dysfunction were statistically significant predictors of mortality. Bleeding from varices and peptic ulcer was associated with a worse prognosis than acute mucosal lesions. It is concluded that clinical and endoscopic factors can be used to identify a group of patients at high risk of further hemorrhage and mortality.

Gastrointestinal hemorrhage due to splenic artery aneurysm pancreatic duct fistula in chronic pancreatitis. A case report and review of the literature.

Gastrointestinal hemorrhage due to splenic artery aneurysm pancreatic duct fistula in chronic pancreatitis is rare. It is, however, important to diagnose this condition particularly in patients having chronic pancreatitis, since it may result in a life-threatening situation. The diagnosis is usually difficult to establish and it may take repeated admissions for intermittent gastrointestinal bleeding until the real source is recognized. Clinical attacks of epigastric pain followed by GI-bleeding 30-40 minutes later are characteristic. Occasionally these attacks are followed by transient jaundice. The present case report describes this rare complication and reviews the current literature.

Patterns of gastrointestinal hemorrhage in hemophilia.

Peptic ulcer has been reported to be the cause of bleeding in 53%-85% of hemophiliacs with gastrointestinal hemorrhage (GIH). The management of GIH in hemophiliacs during the past decade has been affected by the availability of plasma concentrates, an increasing occurrence of chronic liver disease, and widespread use of endoscopic procedures. To determine the present patterns of GIH, we reviewed our experience at the Hemophilia Center of Western Pennsylvania during the last 10 yr. Twenty-five (10.3%) of 243 hemophiliacs experienced 41 episodes of GIH. The severity of hemophilia and a history of retroperitoneal hemorrhage were significant risk factors for GIH. Duodenal ulcer (22%), unknown site (22%), and gastritis (14%) were the three most common diagnoses. The use of fiberoptic endoscopy resulted in the recognition of diagnoses such as gastritis, esophagitis, Mallory--Weiss syndrome, and esophageal varices. Red cell transfusion requirements of hemophiliacs with GIH were no different than those of nonhemophiliacs with GIH (p greater than 0.05). The amount of factor VIII replacement used by hemophiliacs with GIH correlated with the severity of gastrointestinal bleeding (p less than 0.01), but not with the cause of gastrointestinal bleeding (p greater than 0.05). In conclusion, hemophiliacs develop GIH secondary to a variety of causes as do nonhemophiliacs. Fiberoptic endoscopy, after correction of factor VIII level to 0.40 U/ml, is a safe and valuable diagnostic procedure in hemophiliacs. The specific etiology of GIH in hemophiliacs should be aggressively sought and appropriate specific therapy provided.

Esophageal visible vessel as a cause of massive upper gastrointestinal hemorrhage.

Besides peptic ulcers, erosions, esophageal varices, tumors and non-variceal esophageal lesions, vascular abnormalities lead to an upper gastrointestinal hemorrhage in 1-5% of cases. Among 581 emergency esophagogastro-duodenoscopies for acute gastrointestinal bleeding performed in our institution between 1987 and 1989, an esophageal visible vessel was found to be the source of massive hemorrhage in five patients. All patients were males with ages ranging from 37 to 84 years. Esophageal visible vessel was localized in one patient in the middle third and in four patients in the distal portion of the esophagus. Using the Forrest classification, endoscopy revealed an oozing hemorrhage (Ib) in two patients and a protruding vessel (IIa) in three patients. Definitive hemostasis could be achieved in all patients by local injection of adrenaline combined with heater probe thermocoagulation. In some patients with recurrent upper gastrointestinal bleeding, visible esophageal vessel is a rare source of bleeding that has not yet been described.

Prospective evaluation of immediate versus delayed refeeding and prognostic value of endoscopy in patients with upper gastrointestinal hemorrhage.

The effects of immediate vs. delayed refeeding and the prognostic value of endoscopic findings in patients with major upper gastrointestinal hemorrhage were assessed in a prospective randomized study. Entry criteria were clinical evidence of major hemorrhage and endoscopic evidence of a Mallory-Weiss tear or an ulcer with a clean base, flat spot, or clot. Two hundred fifty-eight patients were randomly assigned to groups receiving a regular diet immediately or nothing by mouth for 36 hours, then clear liquids for 12 hours, and a regular diet thereafter. Outcomes in the immediate and delayed refeeding groups were comparable: rebleeding occurred in 4% vs. 5%; urgent intervention, 2% vs. 2%; and deaths, 1% vs. 1%, respectively. Rebleeding occurred in 2 (2%) of 96 patients with cleanbased ulcers, 5 (8%) of 65 with ulcers with spots, 3 (14%) of 21 with ulcers with clots (P = 0.05, 3 x 2 chi2 test), and 1 (2%) of 66 with Mallory-Weiss tears. It is concluded that the time of refeeding does not influence the hospital course of patients with a low risk of recurrent bleeding. Patients with clean-based ulcers or nonbleeding Mallory-Weiss tears may be refed and discharged home immediately after stabilization.

A cohort study (with re-sampled comparator groups) to measure the association between new NSAID prescribing and upper gastrointestinal hemorrhage and perforation.

This cohort study examined the relationship between newly prescribed NSAIDs (none in the previous six months) and upper gastrointestinal hemorrhage and perforation in Tayside, Scotland. Exposure was classified by prescription duration. The study population consisted of the population of Tayside. A Comparator Group was chosen at random (within age and sex strata). Two hundred re-sampled comparator groups were created. Statistical analyses were carried out by Poisson regression (repeated for each of the re-samples). The analyses controlled for age, sex, prior hospitalization for upper gastrointestinal events, prior endoscopy, and the use of ulcer healing drugs. There were 78,191 subjects in the NSAID group, and 78,207 in each of the comparator groups. The increased risk with NSAIDs was only apparent for subjects without a history of upper gastrointestinal events; univariate rate ratio = 2.76 (1.90, 4.01). The final, re-sampled estimate of NSAID risk was rate ratio = 2.48 (1.87, 3.29).

Sepsis and upper gastrointestinal hemorrhage due to duodenal-caval fistula: complications of delayed treatment of a penetrating abdominal injury (case report).

Sepsis and upper gastrointestinal hemorrhage due to duodenal-caval fistula complicated delayed treatment of an abdominal gunshot wound. Gastric and duodenal decompression, external drainage of the duodenal repair, and caval ligation are preferred for delayed treatment of combined duodenal and infrarenal vena caval injuries.

Mesenteric angiography for lower gastrointestinal hemorrhage: are there predictors for a positive study?

PURPOSE: Selective mesenteric angiography is an expensive, invasive, diagnostic, and therapeutic tool for lower gastrointestinal hemorrhage. Some institutions have required a positive nuclear medicine bleeding scan before angiography. We have attempted to determine if this is a valid screening test for mesenteric angiography. Are there any other factors to predict which patients are actively bleeding and who will benefit from angiography? METHODS: All cases of mesenteric angiography for hemorrhage performed during a 12-year period were reviewed. RESULTS: A total of 131 angiograms were performed during a 12-year period with 45 patients demonstrating active bleeding; 54 patients had a bleeding scan before angiography. A positive bleeding scan did not increase the percentage of positive angiograms. A history of prior gastrointestinal bleeding, transfusions, orthostatic hypotension, or tachycardia were not predictors for a positive angiogram. DISCUSSION: This study could not identify any single useful predictor that will increase the likelihood of obtaining a positive angiogram. Nuclear medicine scans should not be used routinely as a screening test for angiography.

[Demonstration of gastrointestinal hemorrhages in the acute radiation syndrome].

Increased radioiron excretion with feces following irradiation is a sure indicator of thrombopenia-induced gastrointestinal hemorrhages which are to be regarded as one of the main causes of the acute radiation syndrome or radiation death respectively. We analyzed the daily 59Fe- excretion of whole-body irradiated mice from the 7th to the 16th day after radiation insult, this period being the critical phase in the course of acute radiopathy with a mortality amounting here to about 50% of the irradiated animals (bone-marrow syndrome). On the eleventh day after radiation exposure, 59Fe-excretion of irradiated animals significantly exceeded by more than fivefold that of the controls. If, before radiation exposure, the mice have been treated with the protective agent AET, they survived without exception and, moreover, a significantly reduced 59Fe-excretion was noted too, the control values almost being reached again. By means of the radionuclide 59Fe therefore, ont only statements are possible concerning the functional state of the erythropoietic system, but also troubles of the hemostatic system can be detected, e.g. the pathological transition of blood into the gastrointestinal tract.

Epidemiology and outcome of patients hospitalized with acute lower gastrointestinal hemorrhage: a population-based study.

OBJECTIVES: Population-based data on the epidemiology and outcome of patients hospitalized with acute lower gastrointestinal hemorrhage (ALGIH) are lacking. This survey of the incidence, etiology, therapy, and long-term outcome of patients with ALGIH was conducted in a defined population. METHODS: In a large health maintenance organization, discharge data and colonoscopy records were used to identify adults hospitalized with ALGIH from 1990 to 1993. Data were collected by record review and telephone calls. RESULTS: Two hundred nineteen patients had 235 hospitalizations, yielding an estimated annual incidence rate of 20.5 patients/100,000 (24.2 in males versus 17.2 in females, p < .001). The rate increased > 200-fold from the third to the ninth decades of life. Diagnoses were: colonic diverticulosis, 91 (41.6%); colorectal malignancy, 20 (9.1%); ischemic colitis, 19 (8.7%); miscellaneous, 63 (28.8%); and unknown, 26 (11.9%). Eight (3.6%) patients died in the hospital (5 of 206 (2.4%) with hemorrhage before admission versus 3 of 13 (23.1%) with hemorrhage after admission, p < .001). Follow-up of 210 of 211 (99.5%) survivors was 34.0 +/- 1.1 months. In the 83 diverticulosis patients without definitive therapy, the hemorrhage recurrence rate (Kaplan-Meier method) was 9% at 1 year, 10% at 2 years, 19% at 3 years, and 25% at 4 years. In the 89 diverticulosis patients who survived hospitalization, all-cause mortality rates (none from hemorrhage) were 11% at 1 year, 15% at 2 years, 18% at 3 years, and 20% at 4 years. CONCLUSIONS: Hospitalization with ALGIH is related to age and male gender. After hemorrhage from colonic diverticulosis, the leading cause, rates of ALGIH recurrence and unrelated death are similar during the next 4 years.
