Abstract

Abstract: Recent surgical technical improvements, such as endoscopic surgery with intersphincteric resection (ISR), could help avoid a permanent colostomy for patients with low-lying rectal tumors. However, the problems associated with anal dysfunction following ISR remain unresolved. We performed ISR and temporary ileostomy in a patient with low-lying rectal cancer. After evaluating the stability of the anastomosis, we planned to close the ileostomy, but the patient developed post-operative colonic mucosal prolapse (CMP). Although there are treatment methods available for CMP, there is no consensus on the treatment for post-operative CMP. In this case, we performed Delorme's procedure because the method has been reported to have advantages in terms of improving post-operative anal function. Post-operative anorectal manometry showed improvement in maximum squeeze pressure, and the patient's anal function improved; subsequently, ileostomy closure was performed. Delorme's procedure may be useful for patients with CMP after ISR to achieve good post-operative anal function.
