The patient was a 77-year-old woman who was diagnosed as having a laterally spreading tumor in the sigmoid colon, and treated by endoscopic submucosal dissection (ESD). Two days after the ESD, the patient developed abdominal pain, and as a contrast-enhanced CT revealed ascites, she was referred to our department. We made the diagnosis of perforation of the sigmoid colon and acute diffuse peritonitis, and performed emergency surgery. We performed laparoscopic Hartmann’s procedure, because the patient also had severe coronary artery disease. She was discharged with ADL at the preoperative level, without complications.
