A46 -year-old man developed ulcerative colitis at the age of 19 years. Although the colitis was medically treated, it relapsed and repeated over time. Periodic lower gastrointestinal endoscopy revealed lower rectal cancer, and he was referred to our department of surgery. Previous steroid therapy induced diabetes, and he was obese, with a height of 170.3 cm, weight of 89.6 kg, and BMI of 30.89 kg/m2, indicating that laparoscopic dissection near the anus would be difficult to perform. Therefore, the patient was scheduled for transanal minimally invasive surgery(TAMIS)...

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)...

Stereotactic navigation allows for real-time, image-guided surgery, thus providing an augmented working environment for the operator. This technique can be applied to complex minimally invasive surgery for fixed anatomic targets. Transanal minimally invasive surgery represents a new approach to rectal cancer surgery that is technically demanding and introduces the potential for procedure-specific morbidity. Feasibility of stereotactic navigation for TAMIS-TME has been demonstrated, and this could theoretically translate into improved resection quality by improving the surgeon's spatial awareness...

Low rectal cancer is traditionally treated by abdominoperineal resection. In recent years, several new techniques for the treatment of very low rectal cancer patients aiming to preserve the gastrointestinal continuity and to improve both the oncological as well as the functional outcomes, have been emerged. Literature suggest that when the intersphincteric resection is applied in T1-3 tumors located within 30-35 mm from the anal verge, is technically feasible, safe, with equal oncological outcomes compared to conventional surgery and acceptable quality of life...

The goal of treatment for early stage rectal cancer is to optimize oncologic control while minimizing the long-term impact of treatment on quality of life. The standard of care treatment for most stage I and II rectal cancers is radical surgery alone, specifically total mesorectal excision (TME). For early rectal cancers, this procedure is usually curative but can have a substantial impact on quality of life, including the possibility of permanent colostomy and the potential for short and long-term bowel, bladder, and sexual dysfunction...

In recent 20 years, the most important advancement of rectal cancer surgery is the total mesorectal excision(TME) and laparoscopic minimal invasive surgery. However, visualization of the distal rectum is still troublesome because of narrow pelvic, bulky tumor, and especially obese male patients. A possible solution for this situation is distal rectal mobilization by transanal minimally invasive surgery (TAMIS), or even pure transanal total mesorectal excision (taTME). When people applaud a new era of rectal cancer surgery is coming, we must also concern about the patients selection, the long-term follow up results and even the operative safety...

Transanal minimally invasive surgery (TAMIS) is a kind of minimally invasive surgery that local resection or total mesorectal excision for rectal neoplasm is performed through the use of multichannel port(single port) transanally. Compared to transanal endoscopic microsurgery(TEM) approach, TAMIS offers an alternative to TEM for rectal neoplasm, and shows the advantage of lower cost and shorter learning curve. TAMIS approach has been used not only in the local resection of rectal neoplasm but also in transanal total mesorectal excision (transanal TME), which is also called TAMIS-TME, in recent four years...

Transanal total mesorectal excision (taTME) is a very innovative approach for the treatment of rectal cancer. This technique comes from some concepts such as natural-orifice transluminal endoscopic surgery (NOTES), transanal endoscopic microsurgery(TEM), transanal transabdominal operation(TATA), transanal minimally invasive surgery(TAMIS) and total mesorectum excision (TME). It has emerged in a dozen countries throughout the world in recent years. We have performed taTME in patients after a series of animal and human cadaver operations, and the technique approved by Ethics committee of the Six Affiliated Hospital of Sun Yat-sen University...

BACKGROUND: Natural orifice transluminal endoscopic surgery (NOTES) is currently gaining a lot of attention. NOTES is expected to further reduce surgical trauma and improve patient care due to eliminating abdominal incisions. The interest in transrectal NOTES has grown slowly, because of concerns of bacterial contamination due to transection of the rectum at the start of the procedure. However, different studies already demonstrated that transanal TME (TaTME) can be performed without major complications...

AIM: Nerve-sparing surgery during laparoscopic rectal mobilization is still limited by anatomical constraints such as obesity, the narrowness of the male pelvis, an ultra low rectal cancer or all of these. The transanal approach for total mesorectal excision has overcome the shortcomings of limited access to the rectal 'no-man's land' close to the pelvic floor. The aim of this anatomical study was to define a roadmap of anatomical landmarks for the caudal to cephalic approach so as to standardize nerve-sparing rectal mobilization procedures...

PURPOSE: Sparing the extrinsic autonomic innervation of the internal anal sphincter during total mesorectal excision is important for the preservation of anal sphincter function. This study electrophysiologically confirmed the topography of the internal anal sphincter nerve supply during laparoscopic-assisted transanal minimally invasive surgery for total mesorectal excision. METHODS: This prospective study was conducted at two large multispecialty referral centers...

BACKGROUND: Frameless stereotaxy is an established method for real-time image-guided surgical navigation in neurological surgery. Though this is capable of providing sub-millimeter accuracy, it has not been used by other surgical specialists. METHODS AND PROCEDURE: A patient with locally advanced, distal rectal cancer and tumor abutting the prostate was selected for transanal TME using TAMIS, with intra-operative CT-guided navigation to ensure an R0 resection. RESULTS: The use of stereotactic TAMIS-TME was successfully performed with an accuracy of ±4 mm...

BACKGROUND: The introduction of transanal minimally invasive surgery (TAMIS) in 2009 allowed colorectal surgeons to approach transanal access with a different perspective. This has lead to the development of TAMIS for total mesorectal excision (TME). We have previously described robotic transanal TME and here report our initial experience with the first three human cases performed at a single institution. METHODS: Three patients with distal rectal cancer were selective to undergo robotic transanal TME...

Transanal minimally invasive surgery (TAMIS) was introduced as an alternative to transanal endoscopic microsurgery in 2010. Over the past 4 years, considerable international experience has been gained with this approach. Most published reports focus on TAMIS for local excision of rectal neoplasia, but there are other important applications such as transanal mesorectal excision for rectal cancer. This comprehensive review details the progress with TAMIS since its inception. Robotic transanal surgery is a natural evolution of TAMIS still in its early infancy, which is also reviewed...

BACKGROUND: Transanal TME is a new approach to performing minimally invasive rectal resection. It is particularly well suited for patients with locally advanced distal rectal cancer and obesity, where the abdominal approach is challenging. Transanal TME can be performed with either TAMIS or TEM. Here, we report our initial experience with transanal TME using TAMIS (TAMIS-TME). METHODS: Patients were selected to undergo transanal TME using the TAMIS platform (TAMIS-TME) primarily for malignant disease, but also for select cases of benign disease...

Transanal TME is a new and important application for TAMIS. It allows for resection and mobilization of the rectum while preserving the quality of the mesorectal envelop. This new approach has gained considerable interest not only because of its minimally invasive nature, but because TAMIS-TME offers a solution to one of the most difficult problems in rectal cancer surgery: Specifically, access to the distal rectum in obese male patients with a narrow pelvis. Recently, transanal TME has become one of the most rapidly expanding areas in rectal cancer surgery...
