The importance of accurate diagnosis and vigorous care of the patient with liver disease and gastrointestinal hemorrhage.

Gastrointestinal hemorrhage in the patient with liver disease is often massive and life threatening. Although varices are the most likely cause of hemorrhage, other sources, such as peptic ulcer disease, Mallory-Weiss tears, and portal hypertensive gastropathy, are common. As liver disease is an important risk factor for intractable bleeding and death in patients with gastrointestinal hemorrhage, outcome in these patients is often poor regardless of the cause of the bleeding. Essential elements of initial therapy include prompt and adequate intravascular volume replacement, correction of severe anemia and coagulopathies, and adequate airway management. After initial resuscitation, urgent endoscopy is required to secure the diagnosis and to deliver endoscopic therapy if possible. The specific form of therapy will differ depending on the lesion encountered. Adjunctive measures, such as the administration of antibiotics and drugs that reduce portal pressure, including octreotide, may also improve outcome. Clinical and endoscopic information can be used to predict first bleeding in patients with liver disease. A large body of data supports the use of beta-blockers in the prevention of first bleeding in patients with known varices.

Recognition and management of upper gastrointestinal hemorrhage.

Upper gastrointestinal hemorrhage is a frequent and severe problem in the intensive care unit. Such bleeding results from diverse gastroenterologic causes. Diagnosis and assessment of the severity of bleeding is accomplished primarily through the physical examination; endoscopy is the most sensitive means of establishing a specific site of hemorrhage. Medical management of gastrointestinal hemorrhage includes treatment with the histamine (H2)-receptor antagonists, antacids, or both. Recent studies suggest that continuous infusion of H2-receptor antagonists may be more efficacious than fixed-bolus dosing in prophylaxis of upper gastrointestinal bleeding. It is not known as yet if the continuous infusion regimen will be effective in stopping gastrointestinal bleeding that has already begun.

Effectiveness of current technology in the diagnosis and management of lower gastrointestinal hemorrhage.

Lower gastrointestinal hemorrhage is a common clinical problem for which multiple diagnostic tests and therapeutic interventions have been developed but no optimal approach has been established. We reviewed 107 consecutive patients admitted to the Massachusetts General Hospital for management of acute lower gastrointestinal hemorrhage to determine the effectiveness of diagnostic and management technologies, with particular attention to urgent colonoscopy. Colonoscopy yielded a diagnosis in 90% of patients, provided the opportunity for successful therapy in 9 of 13 patients (69%), and shortened hospital stay. Angiography performed after a scan positive for bleeding was often diagnostic, and angiography provided the means for successful therapy in 5 of 10 patients (50%). Barium enema and sigmoidoscopy had lower clinical yields. Although roles exist for other technologies, colonoscopy is the most convenient and effective first test in the evaluation of patients with significant lower gastrointestinal hemorrhage. Diagnostic yield, therapeutic opportunity, and cost effectiveness are maximized in early studies.

Gastrointestinal hemorrhage due to gastrointestinal Mycobacterium avium intracellulare or esophageal candidiasis in patients with the acquired immunodeficiency syndrome.

A 33-yr-old black intravenous drug abuser with the acquired immunodeficiency syndrome (AIDS) had a massive fatal upper gastrointestinal hemorrhage due to profound and diffuse esophageal ulceration from Candida, as demonstrated by postmortem examination. A 2-yr-old white male with congenitally acquired AIDS had a massive fatal esophageal bleed as a result of esophagitis from Candida albicans, as proven by pathologic examination and culture of endoscopic biopsies. A 27-yr-old black human immunodeficiency virus-seropositive female died from massive lower gastrointestinal bleeding due to extensive small and large intestinal ulceration caused by Mycobacterium avium intracellulare, as proven by microscopic examination and mycobacterial culture of intestinal tissue. These reports extend the clinical spectrum of these infections in AIDS patients by demonstrating that these infections can produce gastrointestinal bleeding.

Frequency and prophylaxis of upper gastrointestinal hemorrhage in critically ill children: a prospective study comparing the efficacy of almagate, ranitidine, and sucralfate. The Gastrointestinal Hemorrhage Study Group.

OBJECTIVE: To determine the occurrence of upper gastrointestinal hemorrhage in critically ill children, and the efficacy of prophylaxis with almagate (antacid), ranitidine, and sucralfate. DESIGN: Prospective, randomized, controlled trial. SETTING: Pediatric ICU of a tertiary care pediatric hospital. PATIENTS: During a 2-yr study period, 165 patients with one or more upper gastrointestinal hemorrhage risk factors were randomized into one of four groups. Twenty-five patients were excluded because of protocol violations. A total of 140 patients completed the study, with 35 patients in each group. INTERVENTIONS: Patients received no treatment in the control group. The antacid group received almagate 0.25 to 0.5 mL/kg every 2 hrs by nasogastric tube. The ranitidine group received 1.5 mg/kg every 6 hrs iv. The sucralfate group received 0.5 to 1 g every 6 hrs by nasogastric tube. METHODS: Gastric pH and macroscopic bleeding were determined every 2 hrs in all patients until the end of the study. Macroscopic bleeding was classified as nonhemorrhage, slight, or important. Microscopic gastric bleeding was researched with guaiac testing in 72 patients (680 samples). The severity of illness was evaluated by using the Therapeutic Intervention Scoring System, Physiologic Stability Index, and the Multiorgan System Failure scores. The risk of upper gastrointestinal hemorrhage was evaluated by the Zinner and Tryba indices, and was modified for children. MEASUREMENTS AND MAIN RESULTS: The occurrence rate of important upper gastrointestinal hemorrhage was higher (by 20%) in the control group than in the rest of the groups (5.7%), p less than .01. There were no differences between the other groups (almagate 5.7%, ranitidine 8.5%, and sucralfate 2.8%). There was a statistically significant correlation between the occurrence rate of important upper gastrointestinal hemorrhage, the scores of severity of illness indices (Therapeutic Intervention Scoring System, Physiologic Stability Index, and the Multiorgan System Failure scoring system), the risk of upper gastrointestinal hemorrhage indices (Zinner and Tryba), and mortality rate. The Zinner index better classified the patients in relation to the onset of important upper gastrointestinal hemorrhage (sensitivity 76.9%, specificity 85.8%). CONCLUSIONS: Upper gastrointestinal hemorrhage is an important complication in critically ill children. Prophylaxis with almagate, ranitidine, or sucralfate reduces the occurrence rate of clinically important gastrointestinal hemorrhage.

Infliximab for severe recurrent Crohn's disease presenting with massive gastrointestinal hemorrhage.

Severe gastrointestinal hemorrhage is an uncommon complication of Crohn's disease. Most bleeding episodes originate from colonic ulcers or ulcerated areas. The management of severe gastrointestinal bleeding in Crohn's disease is a therapeutic challenge. Several approaches including surgical resection, specific medical therapy of Crohn's disease, endoscopic treatment, or angiographic intervention have been attempted, but recurrence of bleeding is high. Monoclonal anti TNFalpha antibodies (infliximab) can induce relatively rapid mucosal healing. We report two cases of severe recurrent Crohn's disease presenting with massive lower gastrointestinal bleeding in which infliximab induced rapid mucosal healing and prevented recurrent bleeding.

Intramural gastrointestinal hemorrhage.

Intramural gastrointestinal hemorrhage should be suspected in patients taking anticoagulants who develop acute abdominal symptoms with clotting parameters out of the therapeutic range. Likewise, patients with inherent bleeding disorders may present with intramural hemorrhage. Characteristic features are seen on radiological examination; ultrasonography or computed tomography may be valuable noninvasive diagnostic approaches. The diagnosis may be supported by abdominal paracentesis. Surgical intervention is not necessary as conservative treatment, with replacement of clotting factors leading to rapid recovery.

Management of gastrointestinal hemorrhage.

Acute gastrointestinal hemorrhage is a common problem that requires prompt recognition and management to prevent serious morbidity and mortality. Management goals are stabilization of the patient with vigorous fluid resuscitation followed by investigation and definitive treatment of the bleeding source. Endoscopy is often the initial diagnostic test and allows therapeutic measures to be performed at the same time.

[Aorto-duodenal fistula--a rare cause of upper gastrointestinal hemorrhage].

Upper gastrointestinal hemorrhage is the most frequent indication for emergency endoscopy. In most of the cases the bleeding is primarily treated endoscopically. The duodenal penetration of an aortic graft implant is a rare condition, only accidentally diagnosed by endoscopy. This condition represents a difficult situation for the endoscopist since it is usually not included in the differential diagnosis. Additionally hemostasis can not be achieved by endoscopic intervention. Therefore the instant realization of this dangerous diagnosis is extremely important, because only surgical therapy in a center of vascular surgery may save the live of the patient.
