Summary
Laparoscopic low anterior resection with total mesorectum excision is a common procedure used in the treatment of stage I-III rectal cancers. The aim of this work is to describe a laparoscopic low anterior resection approach to remove the part of the rectum containing rectal cancer.
Abstract
Over the last few decades, laparoscopic total mesorectum excision has become a common procedure used in the treatment of stage I-III rectal cancers. When the tumor is located in the upper part of the rectum, low anterior resection (LAR) can be performed to remove the part of the rectum containing the tumor. In addition, faster recovery, less blood loss, and lower complications rates have been achieved by laparoscopic approach. In this protocol, the laparoscopic low anterior resection is performed through five cannulas. The rectum is mobilized with laparoscopic devices such as laparoscopic shears. The visceral and parietal pelvic fascia are dissected without injuring the hypogastric nerves and pelvic neurovascular bundles. The part of the rectum containing the tumor is removed and the colon is then attached to the remaining part of the rectum.
Introduction
In 1982, total mesorectal excision (TME) was introduced by a British surgeon, Heald1, entailing an entire removal of the mesorectum, an adipose lymphatic tissue covering the rectum. Subsequently, low anterior resection (LAR) has become the preferred method for patients with rectal carcinoma, as opposed to abdominoperineal resection (APR), as LAR can preserve the sphincter.
Although radiotherapy and chemotherapy have significantly improved during the last few decades, appropriate surgical resection of the primary tumor remains the mainstay of curative treatments2. The anatomic position of the r....
Protocol
This protocol was performed according to the ethical guidelines of the Declaration of Helsinki and approved by the Ethics Committee of Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine.

Representative Results
Intraoperative data
In this protocol, the surgeon selected the medial side approach. The anterior wall of the rectum was lifted up to extend the right-side peritoneum of the rectum. The surgeon used an ultrasonic shear to dissect the peritoneum at promontory level along the concave of peritoneum and toward the peritoneal reflection (Figure 1A). In this protocol, the surgeon used sharp and blunt dissection to incise the .......
Discussion
Over the last three decades, total mesorectum excision (TME) was considered the gold standard for rectal cancer resection. Currently, it has been found by several randomized clinical trials that the oncological outcomes and long-term survival rates were equivalent between open and laparoscopic TME in the treatment of rectal cancer17,18,19. In addition, shorter hospitalization and faster recovery, lower blood loss and lower compl.......
