 A 42-year-old man was referred to our department because of lower abdominal pain and fever. Computed tomography revealed the sigmoid colon with many diverticula and abscess formation around the rectum in the pelvis. We diagnosed the patient as having a mesorectum abscess due to penetration of sigmoid colon diverticulitis. Endoscopic ultrasonography-guided transrectal drainage was performed and an internal fistula tube was placed. After the improvement of inflammation and the reduction of abscess cavity, laparoscopy-assisted low anterior resection was performed. Operative findings revealed that the rectosigmoid colon adhered severely to the left pelvic peritoneum that was thickened and bled easily. The patient was discharged on the 13th postoperative day. No recurrence of perirectal abscess or defecation dysfunction has been observed, five months after the surgery.
