Core tip: In the current era with advances in diagnostic imaging techniques and overutilization of computed tomography, idiopathic or asymptomatic intussusception is being seen more commonly. The majority of adult intussusceptions however, have pathologic etiology. Patients with palpable mass, obstruction, gastrointestinal bleeding, or a lead point on computed tomography should undergo operative exploration. Certain small bowel intussusception may have a benign, physiological cause and laparoscopy with reduction may be an acceptable strategy. However these patients should undergo small bowel enteroscopy or capsule endoscopy if not obstructed to exclude luminal lesions. All colonic intussusceptions should be resected en-bloc without reduction, whereas a more selective approach may be applied for entero-enteric intussusceptions.
