BACKGROUND: Transanal total mesorectal excision (taTME) is an altogether different approach to rectal cancer surgery, and the effects of carbon dioxide (CO2) on this dissection remain poorly described. METHODS: This article critically examines the effect of carbon dioxide insufflation and the workspace it creates during the process of taTME. The unique aspects of insulation with this approach are governed by the laws of physics, especially the principles of fluid dynamics, an area that remains poorly described for laparoscopy and not at all described for taTME...

Transanal total mesorectal excision (taTME) is a novel operative approach of the radical surgery for rectal cancer, and has been a hot topic in colorectal surgery for years. TaTME aims to solve some problems from previous TME, such as exposure of peripheral mid-lower rectal space, judge of distal cutting margin, and to carry out completely minimal invasive operation. According to the degree of completion of different surgical approach, taTME can be divided into laparoscopic assisted taTME (hybrid taTME) and fully through the anal approach to complete the taTME (pure taTME)...

Transanal total mesorectum excision (taTME) is a novel approach to treat rectal cancer by colorectal surgeons. How to standardize taTME is important for colorectal surgeons, especially at their initial attempt. They can start this approach cautiously only after they master skilled laparoscopic technique and pelvic anatomy, get the knowledge of taTME clearly, and are approved by healthcare department. The female patients with age <70 years old, distance of 5 to 7 cm from tumor inferior margin to anal verge, tumor size <3 cm, cTNM stage <T3aN0 are suitable for taTME...

Transanal endoscopic microsurgery (TEM) is currently the only one-port system in endoscopic surgery, which a direct endoluminal approach can lead to the target organ through a natural opening of human body. TEM has been applied in colorectal surgery for over 3 decades. Compared with radical surgery, TEM has the advantages, such as quicker recovery, shorter hospital stay and fewer complications. One perfect TEM surgical system, which mainly consists of three parts, namely peculiar rectoscope for surgery, special surgical instruments and imaging system, is the foundation of standardized development of TEM...

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...

Since the emergence of minimally invasive technology twenty years ago, as a surgical concept and surgical technique for colorectal cancer surgery, its obvious advantages have been recognized. Laparoscopic technology, as one of the most important technology platform, has got a lot of evidence-based support for the oncological safety and effectiveness in colorectal cancer surgery Laparoscopic technique has advantages in terms of identification of anatomic plane and autonomic nerve, protection of pelvic structure, and fine dissection of vessels...

Laparoscopic surgery is proven equal technique to open rectal surgery. Despite advantages, some problems in case of low rectal surgery are existing: visualization of the pelvis, securing safe distal resection margin, preparing single stapled rectal stump with safe conjunction to the colorectal anastomosis. Approximately 500 procedures have been performed worldwide until today by applying Transanal Total Mesorectal Excision (TaTME) technique, which evolved from a combination of laparoscopy and transanal approach...

Since the introduction of transanal endoscopic microsurgery (TEM) in the 1980 s, the minimally invasive transanal approach has been a treatment option for selected patients with colorectal diseases. Recently, transanal minimally invasive surgery (TAMIS) was introduced as an alternative technique. TAMIS is a hybrid between TEM and single-port laparoscopy and was followed by introduction of transanal total mesorectal excision (TaTME). Although the TaTME experience remains preliminary, it appears to be an attractive minimally invasive procedure for carefully selected patients with resectable rectal cancer...

The risk of urethral injury during transanal total mesorectal excision (taTME) is delineated, and potential risk factors for iatrogenic transection are reviewed. A variety of applied and theoretical techniques can be used by surgeons to diminish the risk of injury in males undergoing this operation. Many of the approaches utilize non-optic media and wavelengths beyond the visible light spectrum which can enhance the surgeon's frame of reference. The aim of the present study was to assess the techniques and theoretical approaches to urethral localization during taTME...

BACKGROUND: Urethral injury is a complication feared by surgeons performing transanal TME (TaTME) or abdominoperineal excision (APE) procedures. Injury during TaTME occurs when the prostate is inadvertently mobilised or as a direct injury similar to the direct injury during the perineal dissection of APE procedures. We performed a proof of principle study to assess the feasibility of using indocyanine green (ICG) to fluoresce the urethra in human cadavers. METHODS: Indocyanine green at varying doses was mixed with Instillagel and infiltrated into the urethra of male human cadavers...
