Abstract

PURPOSE
Adult intussusception is uncommon, but an organic lesion is found to be the lead point in 75% to 90% of the cases. This study was designed to review our experience with adult intussusception and to determine if there are any preoperative predictive factors for a malignant lead point.
METHODS
Thirty-three patients over 15 years of age were diagnosed with intussusceptions through operative finding over a period of 20 years. We reviewed the medical records of these patients retrospectively, and preoperative predictive factors of malignant lead points were analyzed.
RESULTS
The preoperative diagnosis of intussusception had been made correctly in 86% of the cases, and computed tomography could find a lead point in 79%. A causative organic lesion was found in 29 patients (88%) pathologically; 16 cases (48%) were due to benign tumors, and 13 (39%) were due to malignant tumors. A malignant lead point was present in four of 21 enteric (20%) versus nine of 13 colonic intussusceptions (75%). The period from symptom appearance to hospital visit showed a more chronic nature in malignant neoplasm than in benign neoplasm (P = 0.006), and the location of causative organic lesion showed significant difference between benign and malignant groups (P = 0.003).
CONCLUSION
Adult intussusceptions are commonly secondary to a pathologic lead point, and a computed tomography is an effective diagnostic tool for finding a lead point preoperatively. The chronic nature of the disease presentation and colonic location of the lead point may suggest a malignant neoplasm.
