Typical clinical manifestations of colonic ischemia include rapid onset of mild abdominal pain and tenderness over the affected bowel, followed by a mild amount of hematochezia within a day of the onset of pain. Most patients have transient, nongangrenous ischemia, but some have severe ischemia.

Angiodysplasia describes abnormal vascular malformations found in the gastrointestinal (GI) tract, especially in the cecum and right colon. These malformations are prone to bleed and may be responsible for painless hematochezia, melena and concomitant anemia. Diagnosis can be made by direct visualization during endoscopy or angiography. Treatment consists of endoscopic interventions, including ...

Squamous cell carcinoma (SCC) of the rectum is a rare occurrence with an incidence rate of 0.1-0.25% per 1,000 cases. Herein, we report a case of a 52-year-old female who presented with a 2-month history of diffuse lower abdominal pain and hematochezia. Abdominal CT scan revealed a 7-cm irregular rectal mass, and the biopsy showed SCC.

Common marmosets (Callithrix jacchus) are frequently used for biomedical research but can be afflicted with diarrhea-a serious and potentially lethal health problem. Enteropathogenic Escherichia coli (EPEC) is thought to be the causative pathogen of hemorrhagic typhlocolitis in common marmosets, but the actual incidence of the disease and the relationship between EPEC and hematochezia are unkno...

BACKGROUND Failure to thrive and hematochezia in children may be alarm signs warranting endoscopy. In contrast, vascular malformations of the small intestine are uncommon in this age group. We report on a female toddler in whom various imaging techniques revealed an unusually large segmental vascular malformation of the ileum as the cause of the child's main clinical symptoms. CASE PRESENTATI...

for about a fifth of all gastrointestinal bleeding cases, and generally has a less severe course and stops spontaneously in most cases (80%–85%) [1–3]. However, some patients require endoscopic, surgical, or angiographic treatment, depending on the nature of the bleed [4]. Endoscopic band ligation (EBL) is effective for the treatment of both variceal and nonvariceal upper gastrointestinal bleed...
