Intussusception in adults and the role of evolving computed tomography technology

Background The purpose of this study was to describe a single institution's experience with adult intussusception and determine how this was influenced by evolving computed tomography (CT) technology. Methods Adults treated between 1978 and 2013 for intussusception were reviewed. CT utilization and utilization of multislice technology over time were determined. Sensitivity of CT was calculated. Results A total of 318 patients were identified. CT utilization was 72% and it increased over time. The number of channels ranged from 1 to 128. CT sensitivity was greater than 85% for single and multislice scanners. A lead point was identified in 69% of patients and a malignancy in 40%. Surgical exploration was required in 60% of patients and 40% were managed nonoperatively. Conclusions The diagnosis of intussusception in adults is increasing over time, particularly idiopathic intussusception. This is associated with increased utilization of highly sensitive CT technology, which facilitates the safe nonoperative management in many patients.
