Sigmoid intussusception rarely presents as rectal prolapse in pediatric patients. In 1990, Ashcraft et al highlighted the importance of preoperative diagnosis for prevention of inappropriate initial treatment and postoperative recurrence. [32] In their series of 46 patients, 2 children required subsequent sigmoid resection. Preoperative contrast enema with a defecating view revealed a coiled-spring appearance typical of sigmoid intussusception. It is also useful in identifying polyps or other leading points.
