The first documented case of high-grade synovial cell sarcoma of the rectum.

A patient presented with signs and symptoms of tenesmus, urgency, and rectal bleeding that she had been experiencing over the course of several months. Full endoscopic evaluation showed a 6-cm submucosal mass approximately 10 cm from the dente line projecting as an endoluminal mass with a large broad base. An initial endoscopic resection was attempted but aborted because of significant hemorrhage, and surgical oncology was consulted.

Upper gastrointestinal bleeding in patients with chronic renal failure.

Endoscopy to evaluate upper gastrointestinal bleeding was done for 482 patients over a 42-month period. Fifty-nine patients (12%) had chronic renal failure and upper gastrointestinal bleeding; the remaining 423 did not have renal failure. Angiodysplasia of the stomach or duodenum was the most frequent source of bleeding in patients with renal failure.
