Total mesorectal excision (TME) is a mile-stone procedure in the history of rectal cancer surgery, but the exposure of surgical field of distal rectum is usually poor in patients with male, obese and narrow pelvis, which may lead to tumor residue and relative complications. Recently, a new technique called transanal TME (taTME) is considered to solve the above problems, but most medical centers are still in the learning curve of this procedure. Therefore, anatomical planes and landmarks of taTME for rectal cancer and prophylaxis of intraoperative complications are induced in this paper, which includes posterior plane: angle of anus and distal mesorectum and bleeding of mesorectum; rectosacral fascia and presacral bleeding; lateral and posterior-lateral plane: posterior branches of pelvic plexus and damage of anal function; anterior plane: vessel branches of neurovascular bundle and bleeding...

BACKGROUND: Several studies have shown the transanal total mesorectal excision (TATME) is emerging as a safe and effective technique for proctectomy. The majority of these studies to date, however, is based on procedures done in centers with teams of two surgeons working simultaneously. Few were performed by single-surgeon teams with sizeable case load. The objective of our study was to identify the feasibility and safety of a single-surgeon TATME. METHODS: Chart review of prospectively collected data on 27 patients who underwent TATME at our institution from June 2015 to September 2016 were included in this study...

Transanal total mesorectal excision (TaTME) is a new surgical technique in the treatment of selected patients with rectal cancer. This manuscript and the accompanying video report with commentary, which is available online, outlines various equipment requirements and step by step aspects of the surgical technique. With respect to the implementation of TaTME particular attention should be paid to the topography and surgical education.

Over the last decade, with the acceptance of the need for improvements in the outcome of patients affected with rectal cancer, there has been a significant increase in the literature regarding treatment options available to patients affected by this disease. That treatment related decisions should be made at a high volume multidisciplinary tumor board, after pre-operative rectal magnetic resonance imaging and the importance of total mesorectal excision (TME) are accepted standard of care. More controversial is the emerging role for watchful waiting rather than radical surgery in complete pathologic responders, which may be appropriate in 20% of patients...

Purpose: There are patients who do not undergo surgery, regardless of tumor response for neoadjuvant chemoradiotherapy (nCRT) in rectal cancer. However, there have been few reports focused on how oncologic outcomes are worse in these patients. We sought to investigate oncologic outcomes for these non-operated patients with rectal cancer after nCRT. Materials and Methods: A total of 1,063 records of patients with rectal cancer who were treated with nCRT from January 2002 to December 2013 were retrospectively reviewed...

Purpose After preoperative chemoradiotherapy followed by total mesorectal excision for locally advanced rectal cancer, patients who experience local or systemic relapse of disease may be eligible for curative salvage surgery, but the benefit of this surgery has not been fully investigated. The purpose of this study was to characterize recurrence patterns and investigate the impact of salvage surgery on survival in patients with rectal cancer after receiving multidisciplinary treatment. Patients and Methods Patients with locally advanced (cT3-4 or cN+) rectal cancer who were treated with preoperative chemoradiotherapy followed by total mesorectal excision at our institution during 1993 to 2008 were identified...

Neo-adjuvant chemoradiotherapy (NACRT) combined with total mesorectal excision (TME) surgery is the main treatment for locally advanced middle-low rectal cancer, and NACRT significantly improves the local control rate of rectal cancer. According to the current guidelines, patients who receive clinical complete response (cCR) after NACRT are recommended for treatment with TME surgery. A few studies have shown that the watch-and-wait (WAW) policy is safe and could ensure anorectal function and quality of life in patients with cCR...

The primary curative modality for localized rectal cancer is total mesorectal excision (TME). Local control rate of rectal cancer has been improved after neoadjuvant chemoradiotherapy and even pathological complete response (pCR) has been demonstrated in a significant minority. Patients who achieve pCR to neoadjuvant chemoradiotherapy have an excellent prognosis compared with those without pCR. If the patients with complete response to neoadjuvant chemoradiation can be demonstrated by clinical findings and medical imaging (cCR), a non-operative management (NOM) strategy may be pursued to preserve sphincter function and avoid complications induced by TME, which is a new tendency in the treatment of rectal cancer in recent years...

Laparoscopic total mesorectal excision (TME) has been commonly applied in the operation of mid-low rectal cancer, but the conventional laparoscopic TME has the disadvantages of major operative difficulty and long learning-curve, due to its limitations of 2-dimension vision and common laparoscopic instruments. Robotic surgical system with high-qualified 3-dimenstion vision and flexible Endo Wrist instruments can overcome those limitations of conventional laparoscopy, and is useful for the TME that demands deep pelvic operation and flexible dissection in the space of distal rectum...

BACKGROUND: The challenge of performing a good total mesorectal excision (TME) dissection, particularly in the distal 1/3 of the rectum, has spurred interest in new techniques. Robotic surgery is advocated by some, and more recently, a "new" approach, the transanal total mesorectal excision, has been popularized to address this problem. While great interest in this technique exists, little long-term outcome data are available. We have been utilizing a transanal abdominal transanal approach to TME in order to facilitate the distal dissection, and here, we provide our long-term outcomes using this approach in the management of rectal cancer...
