[Sphincter-preserving operation for rectal cancer].
Sphincter-preserving operations represent an important model for integrating the goals of surgery for rectal cancers. These goals--the achievement of cure and local control and the preservation of autonomic visceral pelvic functions--are inherently related. Sphincter-preserving procedures are possible for patients with mid-rectal cancers (6 to 10 cm from the anal verge) and for highly selected ...
متن کاملMethods and results of sphincter-preserving surgery for rectal cancer.
BACKGROUND Sphincter preservation is the goal in the treatment of rectal cancer and should be considered in all patients with an intact sphincter. Sphincter preservation for tumors of the upper rectum is easily achieved, but surgical management of cancer of the mid and lower third of the rectum continues to evolve.

متن کاملSurgery of the cancer of the low rectum: towards a conservation of the sphincter
The conventional low former résection with mechanical or manual colo-anal anastomosis is an alternative to the amputation abdomino-périnéale in cancers of the low rectum. The technique of résection inter-sphinctérienne, which includes the ablation of the sphincter intern, allows a conservation sphinctérienne for the rectal tumours juxta and intracanalaires. The néoadjuvants treatments facilitat...
متن کاملOperations Preserving Recognizable Languages
Given a subset S of N, filtering a word a0a1 · · · an by S consists in deleting the letters ai such that i is not in S. By a natural generalization, denote by L[S], where L is a language, the set of all words of L filtered by S. The filtering problem is to characterize the filters S such that, for every recognizable language L, L[S] is recognizable. In this paper, the filtering problem is solve...
متن کاملOperations preserving regular languages
Given a strictly increasing sequence s of non-negative integers, filtering a word a0a1 · · · an by s consists in deleting the letters ai such that i is not in the set {s0, s1, . . .}. By a natural generalization, denote by L[s], where L is a language, the set of all words of L filtered by s. The filtering problem is to characterize the filters s such that, for every regular language L, L[s] is ...
