Technique and Long-Term Results of Intersphincteric Resection for Low Rectal Cancer

PURPOSE  Intersphincteric resection of low rectal tumors is a surgical technique extending rectal resection into the intersphincteric space. This procedure is performed by a synchronous abdominoperineal approach with mesorectal excision and excision of the entire or part of the internal sphincter. This study was designed to evaluate the long-term results of this method focused on continence function and oncologic results.
