[Sphincter saving operation for ulcerative colitis]

For the purpose of attaining radicality, proctocolectomy with ileostomy is a very useful operative method in ulcerative colitis. On the other hand, an operative method which avoids colostomy or ileostomy and employs a sphincter-saving operation when possible is to be favored because this disease usually develops in young and is benign disease. In Japan, the frequency of sphincter-saving operations has increased gradually. Sphincter-saving operations (SSO) have been performed in 21 cases, and the therapeutic results of this operative method will be reported in this paper. Where no stenosis of the recto-anal region is observed, the SSO can be performed even if the rectal lesion is in active stage. The SSO can be performed safely by the multistage operative method even in cases indicated for emergency or urgent operation. The dependence on pharmacotherapy after operation is reduced by setting the range of SSO below the peritoneal reflection. The incidence of anastomotic leak is hight as a post operative complication. Measures to prevent it are important. Autosuture is useful in this capacity. Bowel function after operation does not interfere with social rehabilitation.
