小腸内視鏡検査が診断に有用であった狭窄型虚血性小腸炎の一例

抄録

A 55-year-old man with atrial fibrillation and cerebral infarction presented with one-month history of abdominal pain, watery diarrhea, and hematochezia. Abdominal computed tomography showed wall thickening of a limited area of the jejunum. Although his symptoms improved as a result of fasting and fluid therapy, abdominal pain recurred after the resumption of oral intake. Single-balloon endoscopy revealed multiple round ulcers in the jejunum, and the endoscope could not pass through the area due to stenosis. Microscopic examination of a biopsy of the stricture lesion showed nonspecific inflammatory findings, without malignant or granulomatous findings. Judging from these clinical findings, we diagnosed an ischemic stricture of the small intestine and performed a partial resection with laparoscopy.
