Ischemic bowel injuries are generally caused by arteriosclerosis, thromboembolism, or vasculitis. Ischemic enteritis is less common than ischemic colitis because of the rich collateral arteries of the small intestine. In the present case, smooth muscle degeneration of the mesenteric to the submucosal veins caused ischemic enteritis and small bowel obstruction.
An 85-year-old woman with recurrent enteritis eventually developed small bowel obstruction. We performed laparoscopic partial resection of the small intestine. The pathological findings revealed smooth muscle degeneration of the mesenteric veins that caused ischemic enteritis. Venous changes were detected not only in the injured region, but also in a part of the normal region of the resected specimen. She continued to experience some minor symptoms postoperatively; however, these symptoms subsided in a short period with medicine discontinuation.
This report shows the possibility that a disease causes ischemic enteritis with unique venous pathological changes and may recur postoperatively.
缺血性肠损伤通常由动脉硬化、血栓栓塞或血管炎引起。由于小肠丰富的侧支动脉，缺血性肠炎比缺血性结肠炎少见。在本病例中，肠系膜至黏膜下静脉的平滑肌变性导致缺血性肠炎和小肠梗阻。
一名85岁反复发生肠炎的女性最终发展为小肠梗阻。我们进行了腹腔镜小肠部分切除术。病理结果显示肠系膜静脉平滑肌变性导致缺血性肠炎。不仅在损伤区域，而且在切除标本的部分正常区域也检测到静脉变化。术后她仍有一些轻微症状；然而，停药后这些症状在短时间内消退。
本报告显示了一种疾病导致具有独特静脉病理变化的缺血性肠炎并可能术后复发的可能性。
