Abstract
INTRODUCTION
In male patients with low rectal cancer undergoing abdominoperineal resection (APR), successful dissection of the anterior anorectum is key to reducing the risk of circumferential resection margin involvement, intraoperative bowel perforation, and local recurrence, but it is challenging. To overcome difficulties dissecting the anterior anorectum, we present a safe and feasible procedure using a transperineal endoscopic approach during APR (TpAPR).
MATERIALS AND SURGICAL TECHNIQUE
The male patient is placed in the prone jackknife position. TpAPR precedes the procedure from an abdominal approach. We use some pelvic tissues as clear anatomical landmarks to dissect the anterior anorectum. The key steps of this procedure are shown in the video.
DISCUSSION
The identification of a clear anatomical dissection plane of the anterior anorectum is difficult because of the complex surgical anatomy of the region. Clear anatomical landmarks for dissection of the anterior anorectum are necessary for safe implementation of this procedure. Therefore, TpAPR in the prone jackknife position can be performed to obtain better visualization of each anatomical landmark at a glance.
