Abstract
In order to study sensation in the patients with postoperative imperforate anus, follow up studies were done in 13 cases of low type and 23 cases of high type. High type cases ranged in a age from 7 to 31 years (average 13. 4 years) and low type cases ranged in a age from 6 to 17 years (average 12.5 years). These cases were classified into 2 groups of the closed anus and the opened anus. The sensory tests were checked as pain (applied the needle), touching (applied the cotton thread) and pressure (applied the sack of the needle) in the anal canal mucosa abve 0. 5〜1 cm from the anal verge. All cases of low type had closed anus, normal bowel movements and sensation in the anal canal. Fourteen cases of high type had closed anus. Thirteen cases of 14 cases had pressure sensation and 12 cases had pain and touching sentation. Four cases were normal bowel movements and 10 cases were constipation. But 9 cases of high type had opened anus and only 2 cases had sensation of anal canal. Six cases were incontinence and 3 cases were constipation. From these results, we conclude that closed anus of postoperative imperforate anus is important for good sensation.
