Anal function was studied in 20 normal subjects and in 20 patients who had undergone sphincter-saving resection of the rectum for carcinoma. In each the anastomosis had been constructed 3-7 cm from the anal verge. Inhibition of the internal sphincter was judged to have taken place when distension of a balloon 10 cm from the anal verge produced an immediate fall of at least 20 per cent in resting anal pressure as measured by a balloon probe: inhibition of the external sphincter in response to… CONTINUE READING
