Acute oesophageal necrosis, also known as black oesophagus, is a rare, and potentially lethal syndrome which is often diagnosed incidentally during upper endoscopy for evaluation of upper gastrointestinal bleed. It is characterised by diffuse circumferential black mucosal discolouration in the distal oesophagus secondary to necrosis that may extend proximally to involve variable length of the oesophagus. One theory of pathogenesis is that the relatively low perfusion state in the distal areas of the oesophagus makes it susceptible to mucosal injury...

Gastrointestinal stromal tumor (GIST) is a submucosal tumor which is most commonly found in the stomach and less commonly in small bowel. Small bowel GIST can be difficult to diagnose by conventional imaging and endoscopy techniques. We report a case of obscure GI bleeding due to a stromal tumor (GIST) of the jejunum diagnosed by video capsule endoscopy.

One hundred seventy-two patients requiring upper gastrointestinal tract endoscopy were examined prospectively for evidence of herpes simplex virus type 1 (HSV-1) infection. No viruses were recovered from active ulcers (11 with duodenal and eight with gastric ulcers). Using both enzyme-linked immunosorbent assay (ELISA) and standard complement fixation methods, patients with endoscopically proved active duodenal ulcer had significantly higher mean serum antibody levels to HSV-1 (but not to cytomegalovirus) than those without evidence of peptic ulcer...
