Table 2 Comparison of defecographic and anal manometric findings between pre- and post-treatment of ALTAS in rectocele

From: Changes in anorectal physiology following injection sclerotherapy using aluminum potassium sulfate and tannic acid versus transanal repair in patients with symptomatic rectocele; a retrospective cohort study
