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...

BACKGROUND: Transanal endoscopic microsurgery (TEM) is a minimally invasive technique allowing to excise large rectal adenomas by local approach. This study shows the feasibility and results of a long term experience of TEM applied in this field. METHODS: A retrospective investigation was performed in patients affected by rectal adenomas (5-11 cm in diameter) who had undergone transanal endoscopic microsurgery from 1992 to 2015. A series of 207 patients met the inclusion criteria and were analyzed for characteristics, intraoperative and postoperative results and long-term follow-up...

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...

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...

BACKGROUND: Rectovaginal fistulas (RVFs) are abnormal connections between the rectum and vagina. Although many surgical approaches to correct them have been attempted, management of RVFs still remains a challenge, especially for recurrent RVFs. METHODS: In the present study, we report a case in a 22-year-old female with a chief complaint of obvious passages of flatus or stool through the vagina for 10 years. She had suffered a vaginal trauma from a violent accident 10 years prior, and gradually noticed the uncontrollable passage of gas or feces from the vagina 2 weeks later...

Appropriate endoscopic resection for colorectal polyps can present a challenge to endoscopists, as these lesions may harbor malignancy. With recent advances in endoscopy, however, we are now entering an exciting frontier of endoscopic therapy for gastrointestinal lesions. These techniques include endoluminal mucosal resection and endoscopic submucosal dissection, which may be utilized on several colonic lesions. This article will discuss these principle endoscopic techniques, their outcomes, and briefly highlight their influence on endoscopic interventions, including transanal endoscopic microsurgery and natural orifice transluminal endoscopic surgery...

Iatrogenic colonic perforations are relatively uncommon but serious complications of diagnostic and therapeutic colonoscopies. Transanal endoscopic microsurgery (TEM) is an useful approach to the rectum and may be used for repair of a rectal perforation during colonoscopy. A 56-year-old male had an iatrogenic perforation of the rectum during a routine follow-up colonoscopy repaired by TEM with an uneventful and rapid recovery.
