Reappraisal of endorectal pull-through procedure. II. Animal experiment.
Anorectal manometry and pelvic histology following endorectal pull-through and simple abdominoperineal pull-through procedures were studied experimentally in dogs. dogs that had undergone endorectal pull-through preserved normal resting pressure of the anal canal, rectoanal reflex response, and intact perirectal anatomy. Dogs that had simple abdominoperineal pull-through, on the other hand, showed low anal canal pressure, loss of rectoanal reflex, and damage of the pelvic muscles. good continence following endorectal pull-through operation was supported by these physiologic and anatomic studies.
