Abdominoperineal resection removes entire rectum, anus, and sphincter complex for very low rectal cancers. Creates permanent colostomy. Only option when tumor proximity to anus precludes sphincter-saving surgery.
Two-team approach: abdominal team performs colostomy and rectal mobilization. Perineal team removes anus, sphincter, and surrounding tissue. Primary closure of perineal wound.
Hospital stay 5-7 days. Perineal wound healing 6-8 weeks. Return to activities 6-8 weeks. Colostomy adjustment 3-6 months. Most patients adapt well to colostomy and resume normal activities.
Local recurrence <5% with complete resection. Survival rates similar to LAR when appropriate patient selected. Excellent oncological control. Colostomy becomes second nature for most patients.
Accurate estimate can be obtained from hospital while visiting the doctor.
