ABSTRACT
Intraabdominal abscess, resulting from primary intraperitoneal disease such as appendicitis, diverticulitis or as a complication of surgery, remains a serious problem with high mortality if not treated early and adequately. In the case of acute bowel perforation, surgery is the treatment of choice, but radiologically guided percutaneous drainage is very effective for the subacute and localized abscess within the peritoneal cavity. However, perirectal abscesses located deep within the pelvis are unapproachable percutaneously because of interposed structures such as the urinary bladder, loops of bowel. Transrectal drainage overcomes these limitations. We present here a case of perirectal abscess treated successfully and safe with transrectal catheter drainge.
