Risk factors associated with poor outcome include advancing age, liver disease, patient presenting in hypovolaemic shock, and current inpatients (who have almost 4 times associated mortality compared to an outpatient at presentation). [teachmesurgery.com]

Small arteriovenous communications are also present and are due to incompetence of the precapillary sphincter. [gastrointestinalatlas.com]

Patients often present with heme-positive stools or modest amounts of bright red blood from the rectum. Bleeding is often intermittent, sometimes with long periods between episodes. Patients with upper GI lesions may present with melena. [msdmanuals.com]

Physicians should thus decide which test to use based on individual clinical presentation, Dr. Leighton advised. [acphospitalist.org]

All patients presented with severe anemia requiring transfusion. GI hemorrhage ceased spontaneously in three cases and after treatment with argon plasma coagulation in another. [sjkdt.org]

• Melena

  Case 4 A 40-year-old female, who had been on chronic hemodialysis for six years for undetermined nephropathy, developed GI hemorrhage with melena. [sjkdt.org]

  Black, tarry stools ( melena ) and occasional episodes of bright red blood rectal bleeding ( hematochezia ) may be the only obvious signs of angiodysplasia. [healthhype.com]

  Overt bleeding consisted of hematemesis in 3 cases, melena in 34 cases and hematochezia in 18 cases.The sites involved in angiodysplastic lesions were: gastric in 18 cases (26%), small bowel 14 (20%), colon 53 (77%), including predominantly the right [latunisiemedicale.com]

  Patients with upper GI lesions may present with melena. Major bleeding is unusual. Vascular lesions are most commonly diagnosed endoscopically. [msdmanuals.com]

  Like most cases of GI bleeding, upper GI lesions are more likely to present as haematemesis or melena, whereas lower GI lesions (more common in angiodysplasia) are more likely to present as haematochezia. Signs on examination are usually minimal. [teachmesurgery.com]

In general, surgery for obscure GI bleeding is indicated for patients who continue to bleed and have had negative endoscopic and radiologic workups, and who are clearly operative candidates. [acphospitalist.org]

During workup, packed red blood cells (RBCs) were transfused. The level of hemoglobin increased to 9.3 g/dL and remained stable. Dyspnea was relieved, with stable vital signs. He was discharged with the instruction to take aspirin only. [e-ce.org]

Outlook (Prognosis) People who have bleeding related to this condition despite having had colonoscopy, angiography, or surgery are likely to have more bleeding in the future. The outlook remains good if the bleeding is controlled. [ufhealth.org]

Among the treatment modalities, surgery can be considered when endoscopic or angiographic treatment is not suitable, or when the patient has poor prognosis factors. Fig. 1. [e-ce.org]

Angiodysplasia (AD) of the small bowel is the most frequent etiology of otherwise unexplained gastrointestinal bleeding and chronic anemia after negative endoscopic screening, as usually demonstrated by wireless capsule endoscopy (WCE). [em-consulte.com]

In this case the exact etiology remained uncertain even after extensive investigations. Most of the common causes of malena in children were ruled out by pre-operative investigations and intra-operative examination. [tropicalgastro.com]
