title: [Ultra-low laparoscopic rectal resection and colo-anal anastomosis. Experimental study on swine].
abstract: Nowadays oncologic surgery is defining new criteria in the treatment of rectal cancer: preservation of sfincterial function, ultra-low resections with distal margin at only 2 cm distally to the tumor, role of mesorectum as preferential site of lymphatic diffusion, preservation of lombo-aortic and pelvic nerves. Laparoscopy is showing good results in bowel surgery so as previously got on biliary tract: less visceral manipulation, less stimulation of immunologic system, less pain, early resumption of peristalsis and food intake, better recovery, less hospital stay. We experimented on pig ultra-low laparoscopic resection of the rectum, with preservation of sfincterial function, and mechanical anastomosis at the upper edge of the sfincterial ring. The evaluation of surgical technique, post-operative supervision, and follow-up instrumental control (anal manometry, endo-rectal ultrasonography, sfincterial electtromanometry, Rx barium enema) show technical feasibility and confirm a better recovery with regular defecatory function.
