[Sphincter function after rectal resection with peranal anastomosis (author's transl)].

To test sphincter function after rectal resection with colon-anal anastomosis performed with Park's peranal technique, 17 patients were examined using the Kelly code and manometric studies. Compliance and anal resting pressure were reduced. Sphincter internal relaxation after rectal distension was also less compared to the norm. Continence was normal for 10 patients and 4 had satisfactory function.
