Two cases of sigmoid-rectal intussusception in adults were presented and together with a review of other five cases of intussusception in adults for the past twenty years in our hospital. Of the 7 intussusceptions, one was in the small intestine and the other 6, in the colon. The youngest patient was 30 years old and the oldest, 82. Four patients were females over 70 years old. Malignant neoplasms were responsible for 4 intussusceptions of the colon. Macroscopically, 5 tumors were of non-ulcerative protuberant and non-circular types. Two of these were benign villous adenomas. Although it is generally agreed that resection without reduction is preferable for the treatment of adult colonic intussusception because of the high probability of malignancy, in some cases having poor risks such as an advanced age and ileus, initial reduction seems necessary so as to minimize surgical intervention.
