摘　　要：BACKGROUND Indwelling colon is characterized by an excluded segment of the colon after surgical diversion of the fecal stream with colostomy so that contents are unable to pass through this part of the colon.We report a rare case of purulent colonic necrosis that occurred 7 years after surgical colonic exclusion.CASE SUMMARY A 73-year-old male had undergone extended radical resection for rectosigmoid cancer.The invaded ileocecal area and sigmoid colon were removed during the procedure,and the ileum was anastomosed side-to-side with the rectum.The excluded ascending,transverse,and descending colon were sealed at both ends and left in the abdomen.After 7 years,the patient developed persistent abdominal pain and distension.Work-up indicated intestinal obstruction.The patient underwent ultrasound-guided catheter drainage of the descending colon and a large amount of viscous liquid was drained,but the symptoms persisted;therefore,surgery was planned.Intraoperatively,extensive adhesions were found in the abdominal cavity,and the small intestine and the indwelling colon were widely dilated.The dilated colon was 56 cm long,5 cm wide(diameter),and contained about 1500 mL of viscous liquid.The indwelling colon was surgically removed and its histopathological examination revealed colonic congestion and necrosis with hyperplasia of granulation tissue.The bacterial culture of the secretions was negative.The patient recovered after the operation.CONCLUSION Although colonic exclusion is routinely performed,this report aimed to increase awareness regarding the possible long-term complications of indwelling colon.
