[The time of proctectomy during ileo-anal anastomosis]

Proctectomy is one of the most important operative phases of ileal pouch-anal anastomosis. It allows complete resection of the rectal mucosa and determines the quality of the postoperative course and the functional results. Two procedures are described, either with a distal rectal mucosectomy or complete resection of the rectal wall as far as the pectinate line. Functional results are identical. The second procedure leads to a complete resection of the rectal mucosa and therefore will be indicated in cases of low rectal cancer of dysplasia when the anus can be preserved.
