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.
