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...

Diseases of the lower and middle third of the rectum, the so called "no-man's territory" traditionally represent a major surgical problem. Minimally invasive surgical techniques significantly contribute to the safe and precise management of this part of the rectum. Traditional laparoscopic instruments via a specifically designed operative anoscope with single-port surgical technique are used during TAMIS (transanal endoscopic minimally invasive surgery). Since the description of the procedure in 2009 a number of case series have proven the feasibility and safety of the technique in the treatment of rectal adenomas...
