Transanal excision (TAE) with conventional retractors and transanal endoscopic microsurgery (TEM) are two well established minimally invasive surgical options for the treatment of selected rectal cancers. TEM is nowadays considered the standard of care for the transanal excision of rectal tumors, since it is associated with significantly better quality of excision and lower rates of recurrence than TAE. When compared with rectal resection and total mesorectal excision, TEM has lower postoperative morbidity and better functional outcomes, with similar long-term survival rates in selected early rectal cancers...

BACKGROUND: Surgery for the treatment of recurrent pelvic malignancy is challenging. Sphincter-preserving surgery (SPS) has been applied in limited cases. Transanal endoscopic approach (TEA) has been used for primary rectal cancer, predominantly for hybrid transabdominal-transanal total mesorectal excision. Here, we describe the use of TEA as a hybrid approach in a case of recurrent ovarian cancer. CASE PRESENTATION: A 59-year-old woman had recurrence of serous ovarian adenocarcinoma in the vaginal stump, near the site of anastomosis from a rectal resection 18 months previously...

Introduction: For a long time, the comprehensive application of minimally invasive techniques in lower gastrointestinal (GI) surgery was substantially impaired by inherent anatomical and technical complexities. Recently, several new techniques such as robotic operating platforms and transanal total mesorectal excision (taTME) have revolutionized the minimally invasive approach. This review aims to depict the current state of the art and evaluates the advantages and drawbacks in regard to perioperative outcome and quality of oncological resection...

The gold standard for curative treatment of locally advanced rectal cancer involves radical resection with a total mesorectal excision (TME). TME is the most effective treatment strategy to reduce local recurrence and improve survival outcomes regardless of the surgical platform used. However, there are associated morbidities, functional consequences, and quality of life (QoL) issues associated with TME; these risks must be considered during the modern-day multidisciplinary treatment for rectal cancer. This has led to the development of new surgical techniques to improve patient, oncologic, and QoL outcomes...

Colorectal cancer is the 3rd most commonly diagnosed cancer, with rectal cancer specifically accounting for 1/3 of new cases. Despite advances in care, there is still a lack of standardization in diagnosis, staging, and treatment, with associated high rates of positive margins, recurrence, and mortality. The gold standard for curative resection remains a total mesorectal excision(TME), and the quality of the TME is one of the most important prognostic factors for local recurrence. The proper TME specimen with negative resection margins is inherently challenging due to patient and tumour-related factors...

Intersphincteric resection(ISR) is a valuable anus-preserving operation that avoids the need for permanent stoma in patients with super low rectal cancer. Recently, with the application and promotion of ISR, the rate of anus-preservation has been greatly elevated, however, some patients following ISR had poor anal function. Based on the knowledge of anal canal anatomical features for better anal function, we propose conformal sphincter-preserving operation (CSPO) for super low rectal cancer, which is a new integrated anus-preservation procedure with total mesorectal excision (TME), coloanal anastomosis, pull through resection, anal canal dissection, local resection and natural orifice transluminal endoscopic surgery technology...

BACKGROUND: Transanal total mesorectal excision (TaTME) provides an excellent view of the resection margins for rectal cancer from below, but is challenging due to few anatomical landmarks. During implementation of this technique, patient safety and optimal outcomes need to be ensured. The aim of this study was to evaluate the learning curve of TaTME in patients with rectal cancer in order to optimize future training programs. METHODS: All consecutive patients after TaTME for rectal cancer between February 2012 and January 2017 were included in a single-center database...

PURPOSE: Compared with the open approach, laparoscopic total mesorectal excision (TME) achieves faster patient recovery, reduces morbidity rates, and shortens hospital stay. However, in laparoscopic low anterior resection (L-LAR), conversion to open surgery is required in almost 20% of cases. Transanal TME (Ta-TME) combined with laparoscopy, also called hybrid natural orifice transluminal endoscopic surgery (NOTES), is a less invasive procedure that can overcome some of the limitations of laparoscopic rectal surgery...

BACKGROUND: Since 2010, comparative studies on transanal and laparoscopic total mesorectal excision (TME) have been published and it remains unclear about the oncological benefit from transanal total mesorectal excision (taTME). METHODS: We have searched English databases to identify all taTME studies published between January 2010 and August 2017. Pathological outcomes included circumferential resection margin (CRM), positive CRM (< 1 M), length of distal resection margin (DRM), positive DRM, quality of mesorectum (complete mesorectum), harvested lymph node, and length of the specimen...

INTRODUCTION: Locally advanced rectal cancers are most often treated with neoadjuvant chemoradiation followed by surgical resection. However, there are differing opinions surrounding management of rectal cancer, including a lack of consensus on the optimal time interval between chemoradiation and surgery, and the management of patients with complete clinical response following neoadjuvant therapy. This study seeks to summarize management trends for rectal cancer among a sample of Canadian surgeons...

Some clinical trials demonstrated local resection for clinical T1 rectal cancer was safe and effective. But for clinical T2 rectal cancer, the results were controversial. Neoadjuvant therapy (NT) is proven to reduce the opportunity of advanced rectal cancer recurrence in various researches. The objective of this Meta-Analysis was to evaluate the oncological outcomes of transanal endoscopic microsurgery (TEM) with or without NT comparing with conventional total mesorectal excision (TME) for the treatment of clinical T2 rectal cancer...

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)...

Radical surgeries and(neo) adjuvant therapies have significantly prolonged survival of patients with colorectal cancer. Microinvasive surgery and function preservation become more important with the prerequisite of R0 resection. As for colorectal cancer, long term survival after laparoscopic curative surgery is proved non-inferior to its open counterpart. The new transanal approach of total mesorectal excision, while avoiding abdominal incision for extraction, may as well improve surgical quality. Local excision and the "watch and wait" strategy, though attractive for organ-preservation, are undermined by suboptimal clinical and radiographic assessment of lymph node and treatment response, respectively...

Transanal total mesorectal excision (taTME) has been proposed to overcome the limitations of laparoscopic TME. The robotic surgical platform has already established its benefits in providing superior ergonomics, and the purported advantages of taTME may play less important a role in the era of robots.
