Ischemic colitis following conservative management of sigmoid volvulus is documented in four cases. Repeat barium enema studies in these patients showed characteristic "thumbprinting", transverse ridging, and mucosal ulcerations within a segment or the entire length of the sigmoid, lasting up to 7 days after nonoperative decompression. The development, extent, and severity of the ischemic changes seem to correlate with the degree of volvulus, blockage of venous and arterial circulation in the sigmoid mesocolon, and increased intraluminal pressure.
四例记录了乙状结肠扭转保守治疗后发生的缺血性结肠炎。对这些患者进行的重复钡灌肠检查显示，在乙状结肠的一段或全长范围内出现特征性的“拇指印征”、横向皱襞和黏膜溃疡，在非手术减压后可持续长达7天。缺血性改变的发生、范围和严重程度似乎与扭转程度、乙状结肠系膜中静脉和动脉循环的阻塞以及管腔内压力升高有关。
