[Clinical investigation of stercoral ulcer].
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.
