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...

RATIONALE: Rectal neuroendocrine tumor (NET) is a relatively rare tumor. Well-differentiated NETs (G1 and G2) rarely display distant metastasis at initial diagnosis. Currently, treatment for the primary lesions of rectal NETs with liver metastasis remains controversial. The liver metastasis was resected in local hospital. Transanal endoscopic microsurgery (TEM) has emerged as an effective minimally invasive surgery for local resection of lower rectal lesions. Herein, we reported the initial application of TEM to remove the rectal primary lesion in patients with low rectal NETs (G2) with giant liver metastases...

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...

PURPOSE: The standard treatment of rectal adenocarcinoma is total mesorectal excision (TME), in many cases requires a temporary or permanent stoma. TME is associated with high morbidity and genitourinary alterations. Transanal endoscopic microsurgery (TEM) allows access to tumors up to 20 cm from the anal verge, achieves minimal postoperative morbidity and mortality rates, and does not require an ostomy. The treatment of T2, N0, and M0 cancers remains controversial. Preoperative chemoradiotherapy (CRT) in association with TEM reduces local recurrence and increases survival...

BACKGROUND: The prevalence of obesity is as high as one-third of the adult population in the ultrasound. Obese patients operated for rectal cancer are less likely to undergo sphincter-preserving surgery, and have an increased morbidity and mortality. We aim to report the outcomes of transanal-endoscopic-microsurgery (TEM) in obese patients with benign and malignant neoplasms. MATERIALS AND METHODS: An analysis was carried out of all patients undergoing TEM at a single institution between 2004 and 2015...

BACKGROUND: Distal rectal cancer resection is an ongoing challenge for the colorectal surgeon. In recent years new technical approaches, especially with implementation of transanal platforms were developed to help in the visualization and resection of these tumors. Nevertheless, the use of these platforms is demanding with significant complications during the onset phase. METHODS: Patients with very low rectal cancer were operated on in a single tertiary center with a combined abdominal and transanal endoscopic microsurgery (TEM) approach...

BACKGROUND: The success of transanal endoscopic microsurgery (TEM) for early rectal cancer depends on proper indications and strict patient selection. When unfavorable pathologic features are identified after TEM operation, total mesorectal excision is recommended to minimize the risk of recurrence. In this study, data were collected in a retrospective series of patients to determine the results of laparoscopic reoperation after TEM. METHODS: All patients underwent an accurate rectal-digital examination and clinical tumor staging by transanal endosonography, CT, and/or MRI...

Liu He, Yi Xiao
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 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...

INTRODUCTION: Transanal minimally invasive surgery (TAMIS) is an endoscopic operating platform for local excision of rectal neoplasms. However, it may be technically demanding, and its learning curve has yet to be adequately defined. The objective of this study was to determine the number of TAMIS procedures for the local excision of rectal neoplasm required to reach proficiency. METHODS AND PROCEDURES: All TAMIS cases performed from 07/2009 to 12/2016 at a single high-volume tertiary care institution for local excision of benign and malignant rectal neoplasia were identified from a prospective database...

REVIEW
Daniel Owen Young, Anjali S Kumar
Local excision (LE) of early-stage rectal cancer avoids the morbidity associated with radical surgery but has historically been associated with inferior oncologic outcomes. Newer techniques, including transanal endoscopic microsurgery (TEM) and transanal minimally invasive surgery (TAMIS), have been developed to improve the quality of LE and extend the benefits of LE to tumors in the more proximal rectum. This article provides an overview of conventional LE, TEM, and TAMIS techniques, including indications for their use and pertinent literature on their associated outcomes for rectal cancer...
