[Defecography and manometry in the postoperative follow-up of patients treated with colo-anal anastomosis by the Parks technique for neoplasm stenosis of the rectum].

The Authors report 15 cases of patients with adenocarcinoma of the rectum who were treated using Park's resection. Morphofunctional parameters are evaluated 3 months after surgery using defecography and manometry before the closure of the neostoma and the reactivation of the ano-rectal canal. Opaque defecography enables the morphology and dimensions of the anal canal to be examined together with modifications to the area between the rectum and the anal canal, and the impression of the pubo-rectal sling. In conclusion these data confirm the importance of surgery, whereas the correlation between defecographic and manometric results allows the functional recovery "ad integrum" of the area to be checked.
