Outcomes of Stapled Transanal Rectal Resection vs . Biofeedback for the Treatment of Outlet Obstruction Associated with Rectal Intussusception and Rectocele: A Multicenter, Randomized, Controlled Trial

In this controlled trial, stapled transanal rectal resection was well tolerated, was more effective than biofeedback training for the resolution of obstructed defecation symptoms, and improved quality of life, with minimal risk of impaired continence. Thus, stapled transanal rectal resection offers a new treatment alternative for obstructed defecation after failure of conservative measures including biofeedback training, a noninvasive approach.
