[Crohn's disease of the large intestine: some problems concerning the surgical therapy (author's transl)].

Experiences with 37 patients operated on Crohn's disease are dealt with. Radical operations are preferred. Limited resections and exstirpations predominate. Colectomy is performed only in case of extensive affection of the large intestine. No type of operation is reliable with regard to recurrence. The prognosis of operations for recurrence is poorer than that of primary operations.
