Retroperitoneal sepsis with mediastinal and subcutaneous emphysema complicating stapled transanal rectal resection (STARR).

The STARR procedure was introduced a few years ago for the treatment of obstructed defaecation syndrome secondary to internal rectal intussusception and rectocele. We present a case of severe retroperitoneal sepsis with mediastinal and subcutaneous emphysema complicating STARR, treated by transperineal pelvic drainage and a loop sigmoid colostomy.
