Stercoral colitis is a rare inflammatory form of colitis that occurs when impacted fecal material leads to distention of the colon and eventually fecaloma formation. Fecalomas can lead to focal pressure necrosis and perforation, while colonic distention and increased intraluminal pressure can lead to compromise of the vascular supply and ischemic colitis. Multiple areas of ulceration can present in the colon. The most common locations of ulceration are in the sigmoid colon and the rectum. When complicated by perforation, the mortality rate can be as high as 32% to 60%. Stercoral colitis most often occurs in patients with a history of chronic constipation, elderly patients with dementia, nursing home or bedbound patients, and occasionally young patients with psychiatric conditions. Chronic constipation is the biggest risk factor for developing stercoral colitis.
粪石性结肠炎是一种罕见的炎症性结肠炎，当干结的粪便导致结肠扩张并最终形成粪石时发生。粪石可导致局灶性压迫性坏死和穿孔，而结肠扩张和管腔内压力升高可导致血管供应受损和缺血性结肠炎。结肠可出现多个溃疡区域。溃疡最常见的部位是乙状结肠和直肠。当并发穿孔时，死亡率可高达32%至60%。粪石性结肠炎最常发生于有慢性便秘病史的患者、患有痴呆的老年患者、养老院或卧床患者，偶尔也发生于患有精神疾病的年轻患者。慢性便秘是发生粪石性结肠炎的最大危险因素。
