Abstract
OBJECTIVE To analyze early and long-term outcomes after total mesorectal excision (TME) and transanal endoscopic microsurgery (TEM) in patients with T1 rectal cancer. MATERIAL AND METHODS A retrospective non-randomized comparative study included 2 groups of patients: group 1 - total mesorectal excision, group 2 - transanal endoscopic microsurgery. In the second group, total mesorectal excision was proposed for patients with tumor invasion depth pT1sm3 and/or lymphovascular invasion and/or low differentiation. If total mesorectal excision was performed as a salvage surgery, the patient was excluded from further analysis. RESULTS There were 156 patients with rectal adenocarcinoma pT1 between October 2011 and August 2019 (102 cases - TEM, 54 cases - TME). We excluded 10 patients from the TEM group due to salvage surgery. Duration of TEM was 40.0 (34; 50) min, TME - 139 (120; 180) min (p=0.00001). Postoperative hospital-stay was also significantly less in the TEM group (7 (6; 9) vs. 10 (7; 11) days, p=0.00001). Six (6.5%) patients in the TEM group and 1 (1.8%) patient in the TME group developed a local recurrence in pelvic cavity (p=0.1). There were no distant metastases. Disease-free 3-year survival was 92% after TEM and 96% after TME (p=0.058). CONCLUSION Transanal endoscopic microsurgery is a relatively safe alternative to total mesorectal excision for early rectal cancer.

Abstract
BACKGROUND In the recent years two innovative approaches have become available for minimally invasive en bloc resections of large non-pedunculated rectal lesions (polyps and early cancers). One is Transanal Minimally Invasive Surgery (TAMIS), the other is Endoscopic Submucosal Dissection (ESD). Both techniques are standard of care, but a direct randomised comparison is lacking. The choice between either of these procedures is dependent on local expertise or availability rather than evidence-based. The European Society for Endoscopy has recommended that a comparison between ESD and local surgical resection is needed to guide decision making for the optimal approach for the removal of large rectal lesions in Western countries. The aim of this study is to directly compare both procedures in a randomised setting with regard to effectiveness, safety and perceived patient burden. METHODS Multicenter randomised trial in 15 hospitals in the Netherlands. Patients with non-pedunculated lesions > 2 cm, where the bulk of the lesion is below 15 cm from the anal verge, will be randomised between either a TAMIS or an ESD procedure. Lesions judged to be deeply invasive by an expert panel will be excluded. The primary endpoint is the cumulative local recurrence rate at follow-up rectoscopy at 12 months. Secondary endpoints are: 1) Radical (R0-) resection rate; 2) Perceived burden and quality of life; 3) Cost effectiveness at 12 months; 4) Surgical referral rate at 12 months; 5) Complication rate; 6) Local recurrence rate at 6 months. For this non-inferiority trial, the total sample size of 198 is based on an expected local recurrence rate of 3% in the ESD group, 6% in the TAMIS group and considering a difference of less than 6% to be non-inferior. DISCUSSION This is the first European randomised controlled trial comparing the effectiveness and safety of TAMIS and ESD for the en bloc resection of large non-pedunculated rectal lesions. This is important as the detection rate of these adenomas is expected to further increase with the introduction of colorectal screening programs throughout Europe. This study will therefore support an optimal use of healthcare resources in the future. TRIAL REGISTRATION Netherlands Trial Register, NL7083 , 06 July 2018.

Abstract
OBJECTIVE Non-randomised studies suggest that endoscopic mucosal resection (EMR) is equally effective in removing large rectal adenomas as transanal endoscopic microsurgery (TEM), but EMR might be more cost-effective and safer. This trial compares the clinical outcome and cost-effectiveness of TEM and EMR for large rectal adenomas. DESIGN Patients with rectal adenomas ≥3 cm, without malignant features, were randomised (1:1) to EMR or TEM, allowing endoscopic removal of residual adenoma at 3 months. Unexpected malignancies were excluded postrandomisation. Primary outcomes were recurrence within 24 months (aiming to demonstrate non-inferiority of EMR, upper limit 10%) and the number of recurrence-free days alive and out of hospital. RESULTS Two hundred and four patients were treated in 18 university and community hospitals. Twenty-seven (13%) had unexpected cancer and were excluded from further analysis. Overall recurrence rates were 15% after EMR and 11% after TEM; statistical non-inferiority was not reached. The numbers of recurrence-free days alive and out of hospital were similar (EMR 609±209, TEM 652±188, p=0.16). Complications occurred in 18% (EMR) versus 26% (TEM) (p=0.23), with major complications occurring in 1% (EMR) versus 8% (TEM) (p=0.064). Quality-adjusted life years were equal in both groups. EMR was approximately €3000 cheaper and therefore more cost-effective. CONCLUSION Under the statistical assumptions of this study, non-inferiority of EMR could not be demonstrated. However, EMR may have potential as the primary method of choice due to a tendency of lower complication rates and a better cost-effectiveness ratio. The high rate of unexpected cancers should be dealt with in further studies.

Abstract
BACKGROUND AND AIMS Large non-pedunculated rectal polyps are most commonly resected by endoscopic mucosal resection (EMR) or transanal endoscopic microsurgery (TEM). Despite pre-procedural diagnostics, unexpected rectal cancer is incidentally encountered within the resected specimen. This study aimed to compare the diagnostic assessment and procedural characteristics of lesions with and without unexpected submucosal invasion. METHODS A post-hoc analysis of a multicenter randomized trial (TREND study) was performed in which patients with a non-pedunculated rectal polyp of ≥3 cm without endoscopic suspicion of invasive growth were randomized between EMR and TEM. RESULTS Unexpected rectal cancer was detected in 13% (27/203) of patients; 15 after EMR and 12 after TEM. Most consisted of low-risk T1 cancers (78%, n = 18). There were no differences in the diagnostic assessment between lesions with and without unexpected submucosal invasion. Diagnostic biopsies revealed similar rates of high-grade dysplasia (28% [7/25] vs 18% [26/144]). When compared with EMR of adenomas, EMR procedures of unexpected cancers had a lower success rate of submucosal lifting (60% vs 93%, P < .001), were more often assessed as endoscopically incomplete (33% vs 10%, P = .01), and were more frequently terminated prematurely (60% vs 8%, P = .001). CONCLUSIONS Diagnostic assessment of large non-pedunculated rectal polyps revealed similar characteristics between unexpected cancers and adenomas. Unexpected cancers during EMR were non-lifting in 40%, endoscopically assessed as incomplete in 33%, and terminated prematurely in 60%. In treatment-naive patients, these factors should raise suspicion of malignancy and need discussion in a multidisciplinary team meeting for decision on further treatment strategies.

Abstract
AIM After endoluminal loco-regional resection (ELRR) by transanal endoscopic microsurgey (TEM) the N parameter may remain undefined. Nucleotide-guided mesorectal excision (NGME) improves the lymph node harvest. The aim of the present study is to evaluate the long-term oncological results after ELRR with NGME. METHOD A total of 57 patients were enrolled over the period January 2001 to June 2015. All patients underwent ELRR by TEM. Prior to surgery, 99 m-technetium-marked nanocolloid was injected into the peritumoural submucosa. After removal of the specimen, the residual defect was probed to detect any residual radioactivity and 'hot' mesorectal fat was excised. All patients were included in a 5-year follow-up programme. RESULTS Significant radioactivity in the residual cavity was found in 28 out of 57 patients (49%). The mean number of lymph nodes harvest in irradiated and nonirradiated patients was 1.66 and 2.76, respectively. After 68.2 months' follow-up overall survival was 91.2%, disease-related mortality 3.5% and disease-free survival 89.5%. Two patients developed pulmonary metastases: one ypT3N0 patient underwent lung lobectomy after chemotherapy and one pT2N0 patient was managed with lung radiotherapy. Both patients are currently alive and disease-free at 48 months' follow-up. Two patients developed local recurrence 1 year after ELRR, both treated with neoadjuvant chemo-radiotherapy and total mesorectal excision. Comparing the present series with previous patients who did not undergo NGME, an increased number of harvested lymph nodes were observed, with a statistically significant difference (P = 0.0085). CONCLUSION NGME during ELRR improves the lymph node harvest and staging accuracy. The long-term results showed satisfactory local (3.5%) and distant (7%) recurrence rates.

Abstract
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. The development of endoscopic submucosal dissection (ESD) and knife assisted resection is described and issues around training reviewed. Efficacy is compared to both EMR and transanal endoscopic microsurgery. The future is considered, including full thickness resection techniques and robotic endoscopy. Expert commentary: The perceived barriers to ESD are falling, and views that such techniques are only possible in Japan are disappearing. The key barriers to uptake will be training, and the development of educational programmes should be seen as a priority. The debate between TEMS and ESD will continue, but ESD is more flexible and cheaper. This will become less significant as the number of endoscopists trained in ESD grows and some TEMS surgeons may shift across towards ESD.

Abstract
BACKGROUND To establish the incidence of unsuspected malignancy in lesions excised through transanal endoscopic microsurgery (TEM) and examine the justification for full-thickness excision of all lesions thought to be benign pre-operatively. METHODS Demographic, operative and pathology data of all patients undergoing TEM at a single institution were collected in a prospectively maintained database. Follow-up data were collected with a focus on polyp recurrence rates and outcome in patients found to harbour malignancy. For lesions thought to be benign pre-operatively, a submucosal excision was routinely performed. RESULTS TEM was attempted in 156 cases between June 1999 and April 2013. Mean (standard deviation) patient age was 66.8 (2.1) years, with 111 males. Mean tumour size was 4.1 (1.6) cm, and mean height from anal verge was 10.4 (2.1) cm. In nine cases, the procedure was unable to be completed and in eight cases a deliberate full-thickness excision was performed. In 139 patients with a presumed benign lesion, mean operating time was 53.4 min. A total of 17 (12.2%) were found to harbour an unsuspected malignancy. Recurrent polyp was seen in 14 (11.7%) of 122 cases of benign pathology (mean follow-up 24.5 months) and was managed by endoscopic means in 10 patients. Mean length of stay was 1.2 days and complications occurred in 7% of cases. No patient with an unsuspected malignancy has developed recurrent disease (mean follow-up 43 months). CONCLUSION Submucosal TEM can result in low complication rates, short duration of surgery, short hospital stay and satisfactory recurrence rates when performed for presumed benign rectal tumours.

Abstract
Purpose To compare medical costs of endoscopic submucosal dissection (ESD) and transanal endoscopic microsurgery (TEM) for the treatment of rectal tumors. Methods The records of 80 patients who underwent ESD and 32 who underwent TEM for the treatment of rectal tumors were collected. Factors compared in the two groups included patient age, sex and clinical characteristics, as well as hospital stay, procedure time, instrument use, medications, postoperative complications, and imaging and laboratory findings. Costs were analyzed based on medical insurance fees, as set publicly by the Ministry of Health & Welfare, Korea. Medical costs were also divided into patient copayments and National Health Insurance (NHI) Corporation charges. Results Patient characteristics, including age, sex, and comorbidities, were similar in the two groups, as were procedure time, histologic diagnosis, tumor size and distance from the anal verge, hospital stay, and complication rates. Median total hospital costs were significantly lower in the ESD than in the TEM group (1,214 United State dollars [USD] vs. 1,686 USD, P < 0.001). The costs for consumables, drugs and laboratory as well as operation fee were also significantly lower in the ESD than in the TEM group. However, patient copayments in the ESD group were significantly higher than in the TEM group (928 USD vs. 496 USD, P < 0.001), because ESD procedure for rectal tumors is not yet covered by the Korean NHI. Conclusion Overall direct medical costs were significantly lower for ESD than for TEM in the treatment of rectal tumors.

Abstract
Transanal endoscopic surgery (TES) consists of a series of anorectal surgical procedures using different devices that are introduced into the anal canal. TES has been developed significantly since it was first used in the 1980s. The key point for the success of these techniques is how accurately patients are selected. The main indication was the resection of endoscopically unresectable adenomas. In recent years, these techniques have become more widespread which has allowed them to be applied in conservative rectal procedures for both benign diseases and selected cases of rectal cancer. For more advanced rectal cancers it should be considered palliative or, in some controlled trials, experimental. The role of newer endoscopic techniques available has not yet been defined. TES may allow for new strategies in the treatment of rectal pathology, like transanal natural orifice transluminal endoscopic surgery or total mesorectal excision.

Abstract
Transanal surgery has and continues to be well accepted for local excision of benign rectal disease not amenable to endoscopic resection. More recently, there has been increasing interest in applying transanal surgery to local resection of early malignant disease. In addition, some groups have started utilizing a transanal route in order to accomplish total mesorectal excision (TME) for more advanced rectal malignancies. We aim to review the role of various transanal and endoscopic techniques in the local resection of benign and malignant rectal disease based on published trial data. Preliminary data on the use of transanal platforms to accomplish TME will also be highlighted. For endoscopically unresectable rectal adenomas, transanal surgery remains a widely accepted method with minimal morbidity that avoids the downsides of a major abdomino-pelvic operation. Transanal endoscopic microsurgery and transanal minimally invasive surgery offer improved visualization and magnification, allowing for finer and more precise dissection of more proximal and larger rectal lesions without compromising patient outcome. Some studies have demonstrated efficacy in utilizing transanal platforms in the surgical management of early rectal malignancies in selected patients. There is an overall higher recurrence rate with transanal surgery with the concern that neither chemoradiation nor salvage surgery may compensate for previous approach and correct the inferior outcome. Application of transanal platforms to accomplish transanal TME in a natural orifice fashion are still in their infancy and currently should be considered experimental. The current data demonstrate that transanal surgery remains an excellent option in the surgical management of benign rectal disease. However, care should be used when selecting patients with malignant disease. The application of transanal platforms continues to evolve. While the new uses of transanal platforms in TME for more advanced rectal malignancy are exciting, it is important to remain cognizant and not sacrifice long term survival for short term decrease in morbidity and improved cosmesis.

Abstract
BACKGROUND AND OBJECTIVE Endoscopic mucosal resection (EMR) of large rectal adenomas is largely being centralized. We assessed the safety and effectiveness of EMR in the rectum in a collaboration of 15 Dutch hospitals. METHODS Prospective, observational study of patients with rectal adenomas >3 cm, resected by piecemeal EMR. Endoscopic treatment of adenoma remnants at 3 months was considered part of the intervention strategy. Outcomes included recurrence after 6, 12 and 24 months and morbidity. RESULTS Sixty-four patients (50% male, age 69 ± 11, 96% ASA 1/2) presented with 65 adenomas (diameter 46 ± 17 mm, distance ab ano 4.5 cm (IQR 1-8), 6% recurrent lesion). Sixty-two procedures (97%) were technically successful. Histopathology revealed invasive carcinoma in three patients (5%), who were excluded from effectiveness analyses. At 3 months' follow-up, 10 patients showed adenoma remnants. Recurrence was diagnosed in 16 patients during follow-up (recurrence rate 25%). Fifteen of 64 patients (23%) experienced 17 postprocedural complications. CONCLUSION In a multicenter collaboration, EMR was feasible in 97% of patients. Recurrence and postprocedural morbidity rates were 25% and 23%. Our results demonstrate the outcomes of EMR in the absence of tertiary referral centers.

Abstract
OBJECTIVE Transanal endoscopic microsurgery (TEM) is an established method for the resection of benign and early malignant rectal lesions. Very recently, TEM via an anally inserted single incision laparoscopic surgery (SILS(®))-port has been proposed to overcome remaining obstacles of the classical TEM equipment. METHODS Nine patients with a total of 12 benign or early stage malignant rectal polyps were operated using the SILS(®)-port for TEM. Patients' and polyps' characteristics, perioperative and postoperative complications, as well as operating and hospitalization time were recorded. RESULTS All 12 polyps (ten low-grade adenoma, one high-grade adenoma, one pT2 carcinoma [preoperatively staged as T1]) were resected. Local full-thickness bowel wall resection was performed for three lesions and submucosal resection for nine lesions. Median operating time was 64 (range 30-180) min. No conversion to laparoscopic or open techniques was necessary. The median maximum diameter of the specimen was 25 (range 3-60) mm, fragmentation of polyps was avoidable in 11 of 12 (92 %) lesions, and resection margins were histologically clear in 11 of 12 (92 %) polyps. Only one patient, in whom three lesions were resected, experienced a complication as postoperative hemorrhage. No mortality occurred. Median hospitalization time was four (range 1-14) days. CONCLUSIONS SILS(®)-TEM is a feasible and safe method, providing numerous advantages in application, handling, and economy compared with the classical TEM technique. SILS(®)-TEM might become a promising alternative to classical TEM. Randomized, controlled trials comparing safety and efficacy of both instrumental settings will be needed in the future.

Abstract
BACKGROUND AND AIM The literature continues to emphasize the advantages of treating patients in "high volume" units by "expert" surgeons, but there is no agreed definition of what is meant by either term. In September 2012, a Consensus Conference on Clinical Competence was organized in Rome as part of the meeting of the National Congress of Italian Surgery (I Congresso Nazionale della Chirurgia Italiana: Unità e valore della chirurgia italiana). The aims were to provide a definition of "expert surgeon" and "high-volume facility" in rectal cancer surgery and to assess their influence on patient outcome. METHOD An Organizing Committee (OC), a Scientific Committee (SC), a Group of Experts (E) and a Panel/Jury (P) were set up for the conduct of the Consensus Conference. Review of the literature focused on three main questions including training, "measuring" of quality and to what extent hospital and surgeon volume affects sphincter-preserving procedures, local recurrence, 30-day morbidity and mortality, survival, function, choice of laparoscopic approach and the choice of transanal endoscopic microsurgery (TEM). RESULTS AND CONCLUSION The difficulties encountered in defining competence in rectal surgery arise from the great heterogeneity of the parameters described in the literature to quantify it. Acquisition of data is difficult as many articles were published many years ago. Even with a focus on surgeon and hospital volume, it is difficult to define their role owing to the variability and the quality of the relevant studies.

Abstract
Rectal adenomas and cancers occur frequently. Small adenomas can be removed colonoscopically, whereas larger polyps are removed via conventional transanal excision. Owing to technical difficulties, adenomas of the mid- and upper rectum require radical resection. Transanal endoscopic microsurgery (TEM) was first designed as an alternative treatment for these lesions. However, since its development TEM has been also used for a variety of rectal lesions, including carcinoids, rectal prolapse and diverticula, early stage carcinomas and palliative resection of rectal cancers. The objective of this review is to describe the current status of TEM in the treatment of rectal lesions. Since the 1980s, TEM has advanced substantially. With low recurrence rates, it is the method of choice for resection of endoscopically unresectable adenomas. Some studies have shown benefits to its use in treating early T1 rectal cancers compared with radical surgery in select patients. However, for more advanced rectal cancers TEM should be considered palliative or experimental. This technique has also been shown to be safe for the treatment of other uncommon rectal tumours, such as carcinoids. Transanal endoscopic microsurgery may allow for new strategies in the treatment of rectal pathology where technical limitations of transanal techniques have limited endoluminal surgical innovations.

Abstract
Transanal endoscopic microsurgery (TEMS) is a well established method of accurate resection of specimens from the rectum under binocular vision. This review examines its role in the treatment of benign conditions of the rectum and the evidence to support its use and compliment existing endoscopic treatments. The evolution of TEMS in early rectal cancer and the concepts and outcomes of how it has been utilised to treat patients so far are presented. The bespoke nature of early rectal cancer treatment is changing the standard algorithms of rectal cancer care. The future of TEMS in the organ preserving treatment of early rectal cancer is discussed and how as clinicians we are able to select the correct patients for neoadjuvant or radical treatments accurately. The role of radiotherapy and outcomes from combination treatment using TEMS are presented with suggestions for areas of future research.

Abstract
BACKGROUND EMR at the anorectal junction (ARJ) is technically challenging. Issues of safety and procedural efficacy dictate that surgery is still performed as the primary management for noninvasive lesions in most centers. Modifications to the standard EMR technique may help to address the unique features and achieve safe and curative resection of most lesions. OBJECTIVE To describe an effective and safe, modified EMR technique to remove advanced mucosal neoplasia (AMN) of the ARJ. DESIGN Prospective, observational cohort study. SETTING Academic, tertiary care referral center. PATIENTS Patients undergoing EMR for AMN at the ARJ over 4.5 years, from June 2008 to December 2012. INTERVENTIONS Use of long-acting local anesthetic in the submucosal injectate, endoscopic resection over the dentate line and hemorrhoidal columns, prophylactic antibiotics for resection of lesions at high risk for bacteremia, and cap and gastroscope-assisted resection. MAIN OUTCOME MEASUREMENTS Procedural success and safety. RESULTS Twenty-six patients with lesions involving the ARJ were referred for EMR (males 53.8%, median age 63, median lesion size 40 mm). Two patients went directly to surgery because of an endoscopic diagnosis of adenocarcinoma. EMR was performed in 24 lesions with complete adenoma clearance achieved in 100%. Four patients were admitted to the hospital. Focal adenoma recurrence was seen in 4 of 18 patients (22%) at first surveillance colonoscopy and was managed by snare diathermy resection. No recurrences were found at the second follow-up colonoscopy. Procedural success, adenoma recurrence, and admission rates were similar between EMRs performed at the ARJ and proximal rectum on univariate analysis (all P > .05). LIMITATIONS Single tertiary center, nonrandomized study. CONCLUSIONS Simple modifications to the EMR technique allow safe and effective treatment of AMN at the ARJ on an outpatient basis and should be the first-line management when the risk of invasive disease is low.

Abstract
Transanal endoscopic microsurgery (TEM) was developed in the early 1980s as a minimally invasive technique allowing the resection of benign rectal adenomas. For this indication, TEM was reported to be safe and effective and even exceeded the results compared to classical local excision. Unsurprisingly, the indication expanded to small rectal cancer. There is still much debate, though, whether it is oncologically safe to perform TEM for rectal cancer. Much has been published about the need for proper patient selection, i.e. patients presenting a low-risk T1 rectal cancer seem to be the most adequate subgroup for this technique. Nevertheless, TEM remains controversial concerning high-risk T1 rectal adenocarcinomas and deeper infiltrating tumors. Several retrospective case series and a small prospective study suggest that radiochemotherapy before local excision reduces recurrence to a level comparable with classic radical surgery (total mesorectal excision). However, these studies are collectively limited, and prospective data from larger multicenter trials are awaited. Reports about functional results after TEM have shown that the procedure has no permanent impact on anorectal function. Even if transient anal resting pressure weakening has been repeatedly described, patients do not suffer from any long-term functional sequelae. Nor do they complain of quality of life impairment.

Abstract
BACKGROUND This study aimed to review the authors' 16-year experience with transanal endoscopic microsurgery (TEM). Mortality, morbidity, recurrence rate, and functional outcome were assessed. New indications and technical improvements are presented. METHODS From November 1991 to August 2008, 123 patients (72 men and 51 women; median age, 68 years; range, 21-91 years) underwent TEM for excision of 105 adenomas with low- or high-grade dysplasia, 9 invasive adenocarcinomas (5 curative and 4 palliative resections), 2 neuroendocrine tumors, and 2 extramucosal lesions. Five additional patients had excisional biopsies, allowing staging after previous endoscopic resection. Most of the resections were full-thickness rectal resections using electrocautery or, more recently, the Harmonic scalpel. The latest mucosectomies were performed using the endoscopic submucosal dissection (ESD) technique. In addition, nontumoral indications included pelvic abscess (7 patients) and rectal strictures, which were either anastomotic or chemical. Pelvic abscesses were drained transrectally, whereas rectal stenoses were treated by strictureplasty. Foreign object retrieval and collagen plug placement for anal fistulas were performed using TEM in three patients. RESULTS No mortality occurred. One intraoperative rectal perforation required conversion to laparotomy. The postoperative complications included one pneumoperitoneum, which was treated medically, and one rectal perforation requiring Hartmann's procedure. In the polyp subgroup, six patients (6/91, 7%) experienced local recurrence. Pelvic abscesses were successfully treated, and stenosis did not recur after strictureplasty. Anorectal manometry showed functional alterations without significant clinical impact. CONCLUSIONS The findings showed TEM to be a safe and effective procedure for local excision of rectal lesions with a low recurrence rate and minimal consequences in terms of anorectal function. In addition, TEM proved to be feasible and effective for pelvic abscess drainage and rectal stenosis treatment. New technologies such as the Harmonic scalpel and ESD increase the precision already offered by this approach.

Abstract
PURPOSE Familial adenomatous polyposis (FAP) is a colorectal disease treated by proctocolectomy. While ileal pouch-anal anastomosis preserves the anus, defecation dysfunction and incontinence can occur. We herein report the results of an improved laparoscopic-assisted ileal pouch-rectal muscle sheath anastomosis after total proctocolectomy which preserves anal function, and compare the results with ileal pouch-anal anastomosis. METHODS A total of 22 patients with FAP were randomized to receive either ileal pouch-anal anastomosis (n = 11) or ileal pouch-rectal muscle sheath anastomosis (n = 11) after total proctocolectomy. Operation time, intraoperative blood loss, postoperative complications, length of hospitalization and postoperative anal pressure, defecation frequency, and quality of life were recorded and compared between the two groups. RESULTS All patients completed a minimum follow-up of 1 year. At the 1 year after the surgery, the daytime defecation frequency was 4.64 ± 0.92 times/day in the ileal pouch-rectal muscle sheath anastomosis group and 6.55 ± 1.13 times/day in the ileal pouch-anal anastomosis group (P = 0.004). Resting anal pressure, maximum squeeze pressure, and average number of daytime defecations in the ileal pouch-rectal muscle sheath group were all better than in the ileal pouch-anal anastomosis group (all, P < 0.05) CONCLUSIONS Ileal pouch-rectal muscle sheath anastomosis is associated with better anal function than ileal pouch-anal anastomosis.

Abstract
PURPOSE OF REVIEW Colorectal cancer screening and prevention is a pivotal element in every gastroenterologist practice. Recent advances in imaging technology and treatment opened the field for endoscopic management of large flat colorectal polyps and early cancer. RECENT FINDINGS High-definition white light colonoscopy allowed for better characterization of colon polyps, particularly flat lesions. Chromoendoscopy facilitated the identification of colon polyps as well as better endoscopic polyp characterization, with strong correlation with final pathological diagnosis, opening the field of 'virtual' biopsy. One particular technology, confocal endomicroscopy can magnify an image approximately 1000 times resembling optical microscopy with very good correlation with histology. Endoscopic mucosal resection has gained great acceptance to manage flat colorectal polyps with the two major complications being bleeding and perforation, both now under 5% in experienced hands. Endoscopic submucosal resection was developed to increase en-bloc resection (less residual disease) of a flat colorectal lesion but one has to accept a higher perforation rate around 10%. SUMMARY Current technology allows for better polyp identification and characterization, which can be managed endoscopically.
