[A Case of Pelvic Abscess Treated with Transperineal Drainage for Lower Gastrointestinal Perforation in Terminal Cancer].

An 83-year-old man with a history of radical cystectomy and ileal conduit construction for bladder cancer, high anterior resection for rectal cancer, and partial hepatectomy for metastatic liver tumors presented with purulent discharge from the perineal region. Abdominal CT revealed gastrointestinal perforation and a pelvic abscess extending continuously to the perineum. Considering his poor general condition and terminal cancer status, a transverse colostomy and transperineal drainage were performed for symptom relief. His postoperative course was favorable, and he was discharged home on postoperative day 33. Transperineal drainage can be considered a feasible palliative treatment for pelvic abscesses extending to the perineum in patients with terminal cancer.
