Bilan d'une expérience de vingt ans d'anastomoses colo-anales. Indications, résultats et pièges

: Seventy nine anastomoses were performed over a 20 year period. Indications included 68 rectal adenocarcinomas and 11 benign lesions. There was no operative mortality. Anastomotic leak was the main cause of morbidity: 12 clinical (15%) and 4 radiological leaks. The 5-year actuarial disease-free survival was 70%, 7 local recurrences (10%) were observed; 6 were Dukes C and 1 Dukes B. Functional results were assessed in 61 patients. They were considered to be excellent in 35 (57%), good in 24 (39%) and bad in 2 (4%). Six failures were noted: 3 technical, 1 oncologic and 2 functional. Pitfalls of coloanal anastomosis are discussed.
