Abstract
A man somewhere in his 60's who had a history of multiple myeloma for years complained of fever and abdominal pain. CT findings showed an abdominal abscess due to perforation of the sigmoid colonic diverticulum. Although percutaneous drainage was effective and the abscess disappeared, the abdominal pain persisted. A colostomy was apparently required but it was hard to perform any surgical procedure because of the patient's poor general condition. Therefore, firstly we performed a percutaneous endoscopic cecostomy (PEC) and secondly dilated the fistula with a balloon. We finally succeeded in adding the function of a colostomy to this procedure using a retractor made of silicone. We did not experience any severe complications during these procedures, and obtained some degree of efficacy.
