Abstract

Abstracts Introduction The understanding of the mechanisms concerning fecal continence has undergone a considerable impulse due to the need to reduce demolition interventions with the possibility of a definitive colostomy. (1,2,3,4) The rectus responsible for the accumulation of faecal material up to moment of defecation does not need a rectal peristaltic activity. the aim of the present study is to evaluate and analyze the functional modifications of ano rectal continence after restoration of intestinal continuity by packaging an anastomosis on the rectal abutment, or in anal colo or on the combed line. Materials and methods : From January 2010 to December 2017 consulted the database of the AOU polyclinic University of Catania were observed in 25 cases of neoplasia in the rectum and in 6 cases of colon neoplasia with seat: sigma (6.2%)) studied at the Department of Medical Surgical Sciences and specialist II Patients selected for this analysis had a mean age of 72 years (range 74-70).
