Answer

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.
