Abstract:
An 85-year-old woman with anemia underwent colonoscopy, which revealed a 25-mm submucosal tumor with ulceration in the lower rectum. Histological examination of a biopsy showed that the lesion was a gastrointestinal stromal tumor (GIST). Subsequent esophagogastroduodenoscopy revealed a submucosal tumor in the duodenum, and examination of a biopsy obtained by endoscopic ultrasound-guided fine-needle aspiration also confirmed that this lesion was a GIST. The rectal lesion was surgically resected to control bleeding and was confirmed as a GIST histologically. Simultaneous development of GISTs in the rectum and duodenum is extremely rare.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
