You are asked to see a 3 year-old boy with obstructive symptoms following laparoscopic transanal Swenson pullthrough for Hirschsprung disease in the neonatal period. Digital rectal examination reveals a widely patent anastomosis. Contrast enema is normal without signs of megacolon. The next best step in the workup and management of this patient is:
A Anorectal manometry
B Colonic manometry
C Botox injection of the internal anal sphincter
D Rectal biopsy
E Bowel management program
