Foot Drop Following Colonoscopy in Children

Foot drop following colonoscopy under general anesthesia is rare in children and is generally unexplained. We report two children who developed foot drop within 12 hours following colonoscopy under general anesthesia and recovered fully within 6 months following physiotherapy. Extensive investigation revealed no etiology. However, we observe that both children had a low BMI, a clinical feature recognized to be associated with common peroneal injury in adults following surgical procedures, but not unique to colonoscopy alone.
