Pull-through procedures performed months to years after permanent proctectomy.

Abstract

Patients who have undergone proctectomy without concomitant rectal reconstruction or coloanal anastomosis were not normally considered candidates for re-establishment of anal continuity until a case report published in 1985. With the addition of nine patients, reported herein is a series of ten patients who have undergone delayed pull-through procedures months to years after permanent proctectomy. Ten patients (including the single case reported in 1985) have undergone delayed pull-through procedures up to 24 years after permanent proctectomy and ostomy formation. Delayed ileal pouch-anal anastomoses were performed in nine patients, and delayed coloanal anastomosis was performed in one patient. There were four males and six females, each of whom had evidence of external sphincter contraction on physical examination. Average age was 33 (range, 24-51) years at the time of reconstruction. Average duration of follow-up is 32 (range, 1-96) months. One patient is awaiting ileostomy closure. Five of nine patients use constipating agents. Two patients are constipated and use enemas to aid in evacuation. None are wearing protective undergarments. One patient had his ileostomy reconstructed eight years after delayed pull-through for uncontrollable diarrhea associated with chemotherapy for multiple myeloma and recently died. Postoperative complications included wound infection (3), enterocutaneous anastomotic stricture requiring anoplasty (2), small bowel obstruction (1), pneumonia (1), presacral abscess (1), and pouchitis (1). Delayed pull-through procedures performed months to years after permanent proctectomy can be performed in selected patients, with results comparable to rectal reconstruction done at the time of proctectomy.
