From 1974 to 1992, 11 cases of adult intussusception were encountered in our department. We perfomed a clinicopathological study of the sites of involvement of intussusception, and classified them into three types: 1) enteric (4 patients), 2)ileocecal (4 patients), which was subclassified into (1) ileo-colic type (1 patient)and (2) ceco-colic type (3 patients), and 3) colonic (3 patients). Average age was 31.0 years in the enteric type, 46.6 years in the ileocecal type and 69.3 years in the colonic type. Duration of symptoms was 59.3 weeks, 33.6 weeks and 1.1 weeks, respectively, the three types, and the rate of accuracy of preoperative diagnosis was 25%, 50% and 100%. etiologically, the underlying pathologic process was identified in 10 patients (91.0%): all intussusceptions of the enteric type (4 patients) were caused by benign disease, 2 of 4 of the ileocecal type were caused by malignant disease and all of the colonic type (3 patients) were caused by malignant disease. In conclusion, intussusception in adults was classified into 3 types. It is necessary to take into consideration the type of intussusception for surglcal treatment.
