Effect of endorectal pullthrough on external anal sphincter integrity (in cases of Hirchsprung’s disease) using EMG

ObjectiveThe transanal mucosectomy of the aganglionic segment is a critical step in the transanal endorectal pullthrough procedure for the treatment of Hirchsprung’s disease. It exerts considerable traction on the anorectal tissue during dissection. Anal sphincter electromyography (EMG) is an indisp
