Analysis of 14 cases of stercoral ulcer showed that they tended to occur in patients over 70 years of age and associated diseases included heart failure under hemodialysis, cerebral hemorrhage, and postoperative states requiring bet rest for long duration. Constipation is always preceded the occurrence of the disease, and the initial symptoms was generally massive hematochezia of sudden onset. Massive blood transfusion was often required, however, heater probe hemostasis was effective. The most common site of involvement was the rectum, and the shape of ulcer was irregular or round. Measurement of the mucosal blood flow in the rectum revealed that blood perfusion was markedly reduced immediately after the occurrence, and that it recovered with healing of ulcer. Ischemia was considered to participate in the pathogenesis of the disease.
对14例粪性溃疡的分析表明，这些溃疡倾向于发生在70岁以上的患者中，相关疾病包括血液透析下的心力衰竭、脑出血以及需要长期卧床休息的术后状态。疾病发生前总是存在便秘，初始症状通常为突然发作的大量便血。通常需要大量输血，然而，热探头止血是有效的。最常受累的部位是直肠，溃疡形状不规则或呈圆形。对直肠黏膜血流的测量显示，疾病发生后立即出现血液灌注明显减少，且随着溃疡愈合而恢复。缺血被认为参与了该疾病的发病机制。
