Founding Director Alberto Peña, MD, revolutionized the treatment of pediatric colorectal patients in 1980 when he introduced a surgical procedure called the posterior sagittal anorectoplasty (PSARP), or pull-through procedure.

The pull-through surgery technique provides greater surgical accuracy in repositioning the anus, minimizes damage to surrounding anatomical structures, reduces post-surgical pain and improves outcomes.

Our surgeons use variations of the PSARP procedure to treat patients with anorectal malformations, cloacal malformations, Hirschsprung’s disease and severe idiopathic constipation.

“Peña Procedure” Helps 3,000th Child

colorectal-PSARP-case-graph-250-imageThe Colorectal Center has changed the quality of life for the 3,000th child with a colorectal problem open to repair via the “Peña pull through procedure,” technically known as posterior sagittal anorectoplasty (PSARP).  

The revolutionary approach has been expanded to many clinical situations since challenging the standard approach 33 years ago that often cut surrounding anatomic structures. Peña’s technique provides greater surgical accuracy in repositioning the anus and minimizes damage.

The colorectal team just celebrated the milestone procedure on Jan. 9.

Peña and Andrea Bischoff, MD, pediatric surgeon in the Colorectal Center, performed the 3,000th surgery for a child in Bolivia when teaching a course there in November 2012. Fifty pediatric surgeons from Bolivia, Peru, Venezuela, Argentina and Brazil attended to learn about the operation and how to improve the functional outcome of patients with colorectal conditions. Our colorectal team has served children from 88 countries and all 50 states.
