Mucocele after endorectal pull-through for imperforate anus

Abstract 

This report documents a patient with imperforate anus in whom an endorectal pull-through with incomplete excision of the macroscopic mucosa led to the formation of a 1,500 mL mucosal lined pelvic mucocele, obstructing both the rectum and ureter. All macroscopic mucosa should be removed during endorectal pull-through. (J Pediatr Surg 1987 Nov;22(11):1023-4)
