Analysis of Clinical Cause and Management of Adult Intussusception: at a Single Institution Experience

The aim of the present study is to analyze the clinical outcomes of intussusception management in adult patients. The data of 56 patients who underwent treatment for adult intussusception from Jan. 2003 to Feb. 2021 were retrieved from a retrospective database and analyzed. The mean age of patients with adult intussusception was 49.9 years. The mean duration of symptoms was 4.8 days. The most common type of intussusception was entero-enteric type (n=30, 53.6%), and the second most common type was ileocolic (n=13, 23.2%). Small bowel intussusception was found in 40 patients (71.4%) and large bowel intussusception in 16 patients (28.6%). Emergency surgery was performed on 30 patients (53.6%). Among the causes of adult intussusception, tumorous lesion accounted for 60.7% (malignancy: 30.4%, benign: 30.4%) and the rate of no tumorous lesion was 39.3%. Forty-four (44) patients (78.6%) received surgical management and 12 patients (21.4%) received conservative management. Bowel resection was performed in 40 patients (71.4%) and manual reduction in 4 patients (7.1%). Conclusively, there are various causes and types of adult intussusception, and appropriate management should be provided to the patient after careful consideration of the cause and type of each intussusception case.
