Abstract

BACKGROUND: The transanal approach to pelvic dissection has gained considerable traction and utilization continues to expand, fueled by the transanal total mesorectal excision (TaTME) for rectal cancer. The same principles and benefits of transanal pelvic dissection may apply to the transanal restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA)-the TaPouch procedure. Our goal was to review the literature to date on the development and current state of the TaPouch. MATERIALS AND METHODS: We performed a PubMed database search for original articles on transanal pelvic dissections, IPAA, and the TaPouch procedure, with a manual search from relevant citations in the reference list. The main outcomes were the technical aspects of the TaPouch, clinical and functional outcomes, and potential advantages, drawbacks, and future direction for the procedure. RESULTS: The conduct of the procedure has been defined, with the safety and feasibility demonstrated in small series. The reported rates of conversion and anastomotic leakage are low. There are no randomized trials or large-scale comparative studies available for comparative effectiveness compared to the traditional IPAA. CONCLUSIONS: The transanal approach to ileal pouch-anal anastomosis is an exciting adaption of the transanal total mesorectal excision for refining the technical steps of a complex operation. Additional experience is needed for comparative outcomes and defining the ideal training and implementation pathways.
