[Perioperative complications in traditional surgery of the rectum].

The authors report their experience of 136 operations for rectal neoplasms, on all of 652 colo-rectal neoplasms, treated from January 1987 to May 1994. In detail the perianastomotic complications have been tested after "traditional" rectal operations: Anterior Resection (RA), Abdomino-perineal amputation (AAP) and Hartmann's procedure. A series of 24 AAP (18%), 81 RA (60%) and 7 Hartmann's procedure have been considered; conversely 18 final and palliative colostomies (13%) and 7 trans-anal operations haven't been taken in to account.
