In order to precise the different prognosised factors of the acute intestinal invagination of the nursling, authors hereby report results of a prospective study lead in the department of general surgery during the period of January 1989 to August 1990. Eleven nursling have been operated during that period. The study of their files showed that the standard clinical triad of the acute intestinal invagination theoretically taught in the schools of health sciences, is never definitive. The diagnostic lateness and indeed therapeutic and the lack of adequate means of pediatric resuscitation constituted the main prognosised factors of this affection. The clinical board of the patients is that of an advanced occlusion or that of a serious peritonis. The surgical operation often consisted in an intestinal resection. The immediate mortality was heavy: 55%. The authors hereby stress the necessity of a training-informing-sensitizing of the health staff in the primary sanitary facilities and the populations.
