BACKGROUND: Early rectal tumor is usually managed by local excision. A novel method-colonoscopy-assisted transanal minimally invasive surgery via glove port (CA-TAMIS-GP)-for resecting early rectal tumor was developed and compared with endoscopic submucosal dissection (ESD). MATERIALS AND METHODS: We performed CA-TAMIS-GP surgery on 26 patients from January 2014 to February 2016. For better analysis, we retrospectively collected data from 31 patients who underwent ESD between October 2012 and December 2013; overall, 57 patients diagnosed with early rectal tumor were included in this study...

BACKGROUND: Complex intraluminal surgical interventions of the gastrointestinal tract are challenging due to the limitation of existing instruments. Our group has developed a master-slave robotic flexible endoscopic platform that provides instrument triangulation in an endoluminal environment. MATERIALS AND METHODS: Colonic endoscopic submucosal dissections (ESD) were carried out in eight pigs. The robot was introduced transanally. A combination of adapted tele-operated instruments was used...

BACKGROUNDS: Although transanal endoscopic surgery is practiced worldwide, there is no consensus on comparative outcomes between transanal endoscopic operation (TEO) and transanal excision (TAE). In this study, we reviewed our experiences with these techniques and compared patients who underwent TEO and TAE using propensity score matching (PSM). METHODS: A total of 207 patients underwent local rectal tumor excision between January 2008 and November 2015. To overcome selection bias, we used PSM to achieve a one-to-one TEO: TAE ratio...

BACKGROUND: Total mesorectal excision is the standard surgical treatment for mid- and low-rectal cancer. Laparoscopy represents a clear leap forward in the management of rectal cancer patients, offering significant improvements in post-operative measures such as pain, first bowel movement, and hospital length of stay. However, there are still some limits to its applications, especially in difficult cases. Such cases may entail either conversion to an open procedure or positive resection margins...

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...

BACKGROUND: Transabdominal laparoscopic proctectomy (LAP) for rectal cancer was associated with postoperative recovery improvement. Early studies showed favorable short-term results of endoscopic transanal proctectomy (ETAP), with low conversion rates to open procedures. We aimed to compare efficacy, morbidity, and functional outcomes of ETAP to standard LAP for low rectal cancer. STUDY DESIGN: From 2008 to 2013, 72 consecutive patients received proctectomy and coloanal manual anastomosis for low rectal adenocarcinoma...

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)...

AIM: To assess the results of treatment for colorectal (CRA), coloanal (CAA) or ileal pouch-anal (IPAA) anastomotic stenosis (AS). METHOD: All patients operated on for AS from 1995 to 2014 were included. Success was defined as the absence of an additional surgical procedure for AS during 12 months after the last procedure and the absence of a stoma at the end of follow-up. RESULTS: Fifty consecutive patients presenting with AS after CRA (n = 16, 32%), CAA (n = 18, 36%) or IPAA (n = 16, 32%), performed for colorectal cancer (n = 28, 56%), familial adenomatous polyposis (n = 5, 10%), inflammatory bowel disease (n = 8, 16%), diverticulitis (n = 4, 8%), benign colorectal neoplasia (n = 3, 6%) or other (n = 2, 4%) underwent a total of 99 procedures including digital (n = 14, 14%), instrumental (n = 38, 38%) or endoscopic dilatation (n = 5, 5%), transanal AS stricturoplasty (n = 9, 10%), transanal circular stapler resection (n = 11, 11%) or transabdominal redo-anastomosis (n = 22, 22%)...

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: Surgery for low rectal cancer remains a challenge when a standard laparoscopic approach is used. Transanal endoscopic total mesorectal excision (TME) has been shown to be feasible and to be associated with a low conversion rate. Combining the transanal and transabdominal single-port approaches (with an abdominal single port implanted in the future stoma and extraction site) could allow TME with minimal wound trauma, low morbidity, and faster recovery. The aim of the current study was to assess the short- and mid-term results of this technique...

PURPOSE: Transanal minimally invasive surgery using single port instrumentation is now well described for the performance of total mesorectal excision with restorative colorectal/anal anastomosis most-often in conjunction with transabdominal multiport assistance. While non-restorative abdomino-endoscopic perineal excision of the anorectum is conceptually similar, it has been less detailed in the literature. METHODS: Consecutive patients undergoing non-restorative ano-proctectomy including a transperineal endoscopic component were analysed...

BACKGROUND: Double and triple stapling techniques to close the rectal stump in laparoscopic anterior resection are fraught with technical drawbacks that could possibly be avoided with the use of the single stapling technique. However, little is known of its safety in laparoscopic surgery or outcomes when combined with natural orifice specimen extraction. OBJECTIVE: This study aims to analyze the feasibility and the operative and immediate postoperative outcomes of single-stapled anastomosis and natural orifice specimen extraction with conventional techniques...
