<b>Purpose:</b> Intussusceptions occurring in adults are relatively rare, however, surgery is usually recommended since they frequently accompany organic lesions as predisposing factor. The purpose of this study is to analyze clinical<br>manifestations and<br>investigate optimal treatment principles for adult intussusception. <b>Methods:</b> Clinicopathogic manifestations of 28 adult intussusception patient were analyzied, retrospectively. The types of adult intussusception were classified as enteric<br>and<br>colonic types. Sex ratio was 15：13 and mean age was 52 (17∼80) years. <b>Results:</b> CT scan was the most accurate tool for diagnosis of adult intussusception and detection of underlying causes. The types of adult intussusception were 4<br>jejuno-jejunal, 7 ileo-ileal, 15 ileo-cecal, and 2 colo-colic types. The pathologic lesions were identified in 23 out of 28 cases (82%). Malignancy was the cause of adult intussusception in 5 cases (45%) of enteric type and in 6 cases (35%) of<br>colonic<br>type intussusception. Operations were performed in 26 cases (93%) and resection without reduction was performed in 23 cases. <b>Conclusions:</b> Surgical exploration without reduction may be the treatment of choice since the majority of cases<br>have<br>organic lesions as the etiology, with relatively frequent association of malignancies.<br>
