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...

RATIONALE: The lower rectal gastrointestinal stromal tumor (GIST) is a rare entity and warrants special attentions because of the considerations of preserving of anal and urinal functions. Neoadjuvant therapy with imatinib mesylate (IM) has achieved great success in GIST, which potentially extends the applications of function-preserving minimally invasive surgical procedures. Transanal endoscopic microsurgery (TEM) is a well-developed minimally invasive technique for benign tumors in lower rectum...

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...

BACKGROUND: Tumor localization may pose a significant challenge during minimally invasive rectal resection. Near-infrared (NIR) imaging can penetrate biological tissue and afford tumor localization from the external surface of the rectum. Our aim was to develop an NIR-based tool for rectal tumor imaging that can be administered intravenously. METHODS: We prepared indocyanine-green (ICG)-loaded liposomes by sonication. Liposomes were evaluated for their size and morphology...

PURPOSE: Transanal endoscopic microsurgery (TEM) is the gold standard for local excision of rectal lesions, but no study exists concerning the best material. The objective was to compare TEM using a disposable material vs a standard platform through a case-matched study. METHODS: Patients who underwent TEM for rectal neoplasms were identified from prospective databases in two tertiary referral centers and matched according to four criteria (sex, tumor location, size, distance from the anal verge): TEM using a disposable material (GelPoint Applied®; group A) and TEM using a standard TEO® platform (Karl Storz, Tuttlingen, Germany; group B)...

BACKGROUND: The incidence of malignant synchronous colorectal tumors (SCRT) is between 2% and 5%, and the association of synchronous adenomatous polyps in colon cancer has been reported to be 15%-50%. Surgical resection is the primary treatment option for SCRT not amendable to endoscopic resection. Lesions in adjacent segments are usually treated with more extensive resection; however, there is still some controversy on how to best treat synchronous lesions in separate segments, especially when the rectum is involved...

AIM: Rates of local recurrence (LR) after transanal endoscopic microsurgery (TEM) for rectal carcinoma vary; the reasons remain unclear. We analyzed LR after TEM for low-risk pT1 (G1/2/X, L0/X) rectal carcinoma to investigate the influence of completeness of resection and occult lymph node metastasis on risk of LR. METHOD: LR location and stage, completeness of resection of primary carcinoma (minimal distance between tumor and resection line ≤1 mm vs >1 mm), and incidence of involved lymph nodes in resected LR specimens were collected, and tumor characteristics of LR were compared with primary carcinoma...

Local surgery for rectal tumors has been traditionally limited due to technical issues for lower risk lesions. In the 1980s, Buess described the transanal endoscopic microsurgery (TEM) technique that enabled excision of lesions that were larger and in a higher location. TEM in a short time became the gold standard for the excision of large adenomas and early rectal carcinomas. Since the advent of TEM, and due to advances in minimal invasive technology, new devices and procedures have come to the surgical armamentarium, in many cases with only very slight differences between them...
