Patient We report a case of an adult in his 5th decade presenting with massive melena. Interventions On presentation the patient was tachycardic (pulse115/min), and hypotensive (BP 80/55 mmHg). His complete physical examination was unremarkable. [doi.org]

• Maroon Stools

  Maroon stools are maroon-colored blood mixed with stool that is often associated with a right colonic source of bleeding; however, it can also result from a more brisk, proximal source of bleeding. [accessmedicine.mhmedical.com]

  stools (16.7%) and melena (11%). [emedicine.medscape.com]

• Rectal Mass

  Additional key elements include a careful and thorough inspection of the anus, palpation for rectal masses, characterization of the stool color, and a stool guaiac card test to evaluate for the presence of blood. [en.wikipedia.org]

• Hypotension

  The patient re-presented to the emergency room with recurrent bleeding, anemia, and hypotension. During a period of active bleeding, a number of diagnostic studies ultimately revealed the source to be the proximal jejunum. [ncbi.nlm.nih.gov]

  Tachycardia and Orthostatic Hypotension. There have been discussions in the literature about other findings to rule in/out upper GI bleeding. [mdedge.com]

Etiology Although lower GI bleeding can occur at any age, specific disease processes are distinctive for different age groups and familiarity with this can help tailor the diagnostic workup 2,6: adolescents and young adults inflammatory bowel disease [radiopaedia.org]

Interestingly a colonoscopy done 6 months earlier for anemia workup was normal. Emergent laparotomy revealed numerous smaller intraluminal nodules scattered throughout the small bowel. Results Histopathology revealed carcinoid tumor. [doi.org]

(PT), platelet count, and/or bleeding time (bleeding time is only recommended in patients with bleeding disorders and in those using antiplatelet agents) Helical computed tomography (CT) scanning of the abdomen and pelvis can be used when a routine workup [emedicine.medscape.com]

• Hyponatremia

  Rarely, this can lead to volume overload and electrolyte abnormalities such as hyponatremia[ 37 ]. There is also the risk for aspiration, especially when the prep is rapid or the patient is at risk for aspiration. [wjgnet.com]

  Complications During vasopressin infusion, monitor patients for recurrent hemorrhage, myocardial ischemia, arrhythmias, hypertension, and volume overload with hyponatremia. Nitroglycerine paste or drip can be used to overcome cardiac complications. [emedicine.medscape.com]

• Salmonella Typhi

  It was complicated with Salmonella typhi infection confirmed later from the blood culture result. [dx.doi.org]

• Multiple Ulcerations

  The combination effect of both S typhi and T. trichiura led to multiple ulcerations and severe bleeding which caused hypovolemic shock. [dx.doi.org]

• Ischemic Changes

  No ischemic change was observed in any patients in group Ia and in two patients in group Ib. Ischemic changes were observed in six group Ib patients and both group II patients. [ncbi.nlm.nih.gov]

(initial hemoglobin level, need for packed red blood cells), and treatment efficiency (necessary reoperation). [ncbi.nlm.nih.gov]

We conclude that in patients with active gastrointestinal bleeding, colonoscopy in combination with scintigraphy detect at a higher rate the cause and the site of bleeding and possibly improve the prognosis. [ncbi.nlm.nih.gov]

We performed such a study to evaluate the clinical presentation, outcome, and mortality as well as clinical variables associated with poor prognosis. Methods. [tandfonline.com]

It also appears that therapeutic colonoscopy can arrest or prevent bleeding in certain high-risk patients, offering the opportunity to change the natural history of the bleed. [ncbi.nlm.nih.gov]
