The principles of TME dissection that should be emphasized include sharp dissection with proper traction-counter traction to expose the avascular plane and excellent lighting. Whether the operation is being performed in an open, laparoscopic, or robotic approach, these basic principles are maintained.

The concept of TME has now also been applied for transanal approaches. A preliminary study by Kang et al 12 demonstrated that transanal total mesorectal excision in rectal cancer is safe and feasible. A radiologist can also predict residual mesorectum on postoperative T2-weighted MRI of the pelvis performed on patients following mesorectal …

Most people with rectal cancer have a TME as part of their surgery. A TME is when the surgeon removes some of the fatty tissue around the rectum (mesorectum). The fatty tissue contains lymph nodes and blood vessels. This means all the lymph nodes near to the tumour are removed, which reduces the risk of the cancer coming back.

Total mesorectal excision is the standard operation for rectal cancer. In this procedure referred to as radical resection in this chapter, the rectum is excised together with the mesorectum, which contains lymphatic tissue draining the rectum. 1 More proximal rectal tumors (upper and mid rectum) can be removed by an anterior resection of the rectum …

Mesorectal Excision Surgery For patients with advanced rectal cancers, surgery that includes total mesorectal excision (TME) often provides the best possible patient outcomes and survival. How total mesorectal excision surgery works The mesorectum is a fatty tissue directly adjacent to the rectum that contains blood vessels and lymph nodes.
Details 
A tailored mesorectal excision (also referred to as a partial mesorectal excision or tumor-specific mesorectal excision) can be employed for cancers in the upper and upper-mid rectum. The rationale for a 5-cm distal margin is based upon data showing longitudinal spread within the tubular lymphatics and lymph nodes of the rectum …

Transanal Total Mesorectal Excision (taTME), also known as 'bottom-up' surgery, is a new minimally invasive robotic alternative to conventional surgery for patients with lower rectal cancer. The main benefit of this procedure is that it allows the surgeon to better visualize and remove the tumor in lower rectal cancers while avoiding a bigger incision on the skin.

DEFINITION. Low anterior rectal resection (LAR) with total mesorectal excision (TME) is defined as the removal of the rectum en bloc with an intact perirectal fascial envelope distal to the cancer-bearing rectal wall. The visceral endopelvic fascia, also known as fascia propria or investing fascia of the mesorectum, is identified by a thin, …

The Dutch ColoRectal Cancer Group, the Nordic Gastro Intestinal Tumour Adjuvant Therapy, and the European Organization for Research and Treatment of Cancer (EORTC) jointly organized a large prospective randomized multicentre trial to investigate the efficacy of preoperative radiotherapy (five fractions of 5 Gy) in combination with standardized …
Details 
Total mesorectal excision (TME) is a common procedure used in the treatment of colorectal cancer in which a significant length of the bowel around the tumor is removed. TME addresses earlier treatment concerns regarding adequate local control of rectal cancer when an anterior resection is performed. The term TME strictly applies in …
