[Is subtotal resection of the colon actual for ulcerative colitis in the century of ileal reservoirs?].

The authors describe results of surgical treatment of 112 patients operated for a severe resistant form of ulcerative colitis (UC). In 26 (23.2%) of observations the operations were performed for complications, in 65 (58%)--for hormone-resistent, and in 21 (18.

[Proctectomy with external sphincter preservation: long-term functional results].

52 patients with the lower ampullary rectal cancer with tumor localization on the dentate line level had been operated with the use of the originally developed reconstructive technique, permitting preservation of the external anal sphincter elements and, consequently, partial continence. Colonic rectal pouch and smooth muscle cuff were performed during the neorectum and neoanus plasty. A protective stoma was performed in all cases.

[Proctectomy with external sphincter elements' preservation in surgery of low-ampullary rectal cancer].

Operational technique for the rectum tumors, localized at the level of dentate line, developed in the State center of coloproctology, allows preservation of external anal sphincter elements and thus, partial preservation of defecation control. Technique is described and proved, preliminary treatment results of 42 patients are analysed. The operation is oncologically effective (local recurrence rate 4,8%).

[Results of surgical treatment of residual and recurrent anal tumors].

Radio- or chemotherapy is a modern standard of anal cancer treatment. Recurrence or partial remission rate after radiochemotherapy achieves 20-40%. The study is aimed to evaluate the role of abdominoperineal resection in the treatment of residual and recurrent anal cancer.
