AIM: Full thickness local excision after neoadjuvant chemoradiotherapy (CRT) for patients with rectal cancer and incomplete clinical response has been a treatment strategy for organ preservation. Follow up of these patients is challenging since anatomic distortion and postoperative changes may be clinically indistinguishable from tumor recurrence. Magnetic resonance imaging (MRI) may have a role in detecting recurrence. The aim of this study is to describe the MRI findings during follow-up in patients having local excision following CRT with and without local recurrence...

Transanal endoscopic surgery (TES) techniques encompass a variety of approaches, including transanal endoscopic microsurgery and transanal minimally invasive surgery. These allow a surgeon to perform local excision of rectal lesions with minimal morbidity and the potential to spare the need for proctectomy. As understanding of the long-term outcomes from these procedures has evolved, so have the indications for TES. In this study, we review the development of TES, its early results, and the evolution of new surgical techniques...

AIM: In patients with rectal cancer, surgery and chemo-radiotherapy may affect the anal sphincter function. Few studies evaluated the ano-rectal function after neoadjuvant chemo-radiotherapy (n-CRT) and/or Transanal Endoscopic Microsurgery (TEM). The aim of this study was to evaluate the effects of n-CRT and TEM on ano-rectal function. METHOD: Thirty-seven patients with rectal cancer underwent ano-rectal manometry and Wexner score for faecal incontinence at baseline, after n-CRT (cT2-T3N0 cancer) and at 4 and 12 months after surgery...

There have been considerable advances in the endoscopic treatment of colorectal neoplasia. The development of endoscopic submucosal dissection and full thickness resection techniques is changing the way benign disease and early cancers are managed. This article reviews the evidence behind these new techniques and discusses where this field is likely to move in the future. Areas covered: A PubMed literature review of resection techniques for colonic neoplasia was performed. The clinical and cost effectiveness of endoscopic mucosal resection (EMR) is examined...

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)...

AIM: Defecography is the standard diagnostic technique for the diagnosis of functional disorders of the posterior pelvic compartment. However it has some limits as radiation exposure, low-contrast resolution, some degrees of embarrassment and discomfort for the patients. Furthermore it often fails to directly visualize the changes that affect the pararectal space. Here we present a never described case of rectal perforation after defecography with barium impaction removed by TEM (Transanal Endoscopic Microsurgery)...

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...

REVIEW

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...

BACKGROUND: In patients who exhibit a complete clinical response after radio-chemotherapy for rectal cancer, the standard surgical approach might constitute overtreatment. The aim of this study is to analyse the outcomes of anorectal function and quality of life after transanal endoscopic microsurgery (TEM) in irradiated patients with complete clinical response. PATIENTS AND METHODS: Between 2007 and 2014, 84 patients who were diagnosed with stage T2-T3-T4 N0 rectal cancer before chemoradiotherapy showed a complete clinical response to neoadjuvant therapy and underwent TEM...

BACKGROUND: Transanal endoscopic microsurgery (TEM) and transanal minimally invasive surgery (TAMIS) have been shown to improve the quality of transanal resections, allowing for improved visibility and access to the proximal rectum. This study compares the short-term outcomes between TEM and TAMIS among experienced colorectal surgeons. METHOD: A retrospective review was conducted for TEM and TAMIS performed from 2012 to 2015 by local colorectal surgeons. Baseline patient demographics, operative variables, pathology results, and short-term outcomes were assessed...
