[DOI: 10.4240/wjgs.v16.i10.3114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2024] [Revised: 07/25/2024] [Accepted: 09/03/2024] [Indexed: 09/27/2024] Open
Abstract
BACKGROUND Total mesorectal excision remains the gold standard for the management of rectal cancer however local excision of early rectal cancer is gaining popularity due to lower morbidity and higher acceptance by the elderly and frail patients.
AIM To investigate the results of local excision of rectal cancer by transanal endoscopic microsurgery (TEMS) approach carried out at three large cancer centers in the United Kingdom.
METHODS TEMS database was retrospectively reviewed to assess demographics, operative findings and post operative clinical and oncological outcomes. This is a retrospective review of the prospective databases, which included all patients operated with TEMS approach, for early rectal cancer (Node-negative T1-T2), selected T3 in unfit/frail patients.
RESULTS Two hundred and twenty-two patients underwent TEMS surgery. This included 144 males (64.9%) and 78 females (35.1%), Median age was 71 years. The median distance of the tumours from the anal verge 4.5 cm. Median tumour size was 2.6 cm. The most frequent operative position of the patient was lithotomy (32.3%), Full-thickness rectal wall excision was done in 204 patients. Median operating time was 90 minutes. Average blood loss was minimal. There were two 90-day mortalities. Complete excision of the tumour with free microscopic margins by > 1mm were accomplished in 171 patients (76.7%). Salvage total mesorectal excision was performed in 42 patients (19.8%). Median disease-free survival was 65 months (range: 3-146 months) (82.8%), and median overall survival was 59 months (0-146 months).
CONCLUSION TEMS provides a promising option for early rectal cancers (Large adenomas-cT1/cT2N0), and selected therapy-responding cancers. Full-thickness complete excision of the tumour is mandatory to avoid jeopardising the oncological outcomes.

J Clin Med 2024; 13:1419. [PMID: 38592246 PMCID: PMC10934864 DOI: 10.3390/jcm13051419] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Revised: 02/20/2024] [Accepted: 02/26/2024] [Indexed: 04/10/2024] Open
Abstract
Background: Local excision by transanal endoscopic microsurgery (TEM) is considered an acceptable treatment for rectal adenomas with high-grade dysplasia (HGD). This study aims to assess the likelihood of harboring an invasive carcinoma in preoperatively diagnosed HGD polyps and evaluate the risk factors for tumor recurrence in patients with final HGD pathology. Methods: Data from patients who underwent TEM procedures for adenomatous lesions with HGD from 2005 to 2018 at the Rabin Medical Center, Hasharon Hospital, were analyzed. Collected data included patient demographics, preoperative workup, tumor characteristics and postoperative results. Follow-up data including recurrence assessment and further treatments were reviewed. The analysis included two subsets: preoperative pathology of HGD (sub-group 1) and postoperative final pathology of HGD (sub-group 2) patients. Results: Forty-five patients were included in the study. Thirty-six patients had a preoperative diagnosis of HGD, with thirteen (36%) showing postoperative invasive carcinoma. Thirty-two patients had a final pathology of HGD, and three (9.4%) experienced tumor recurrence. Large tumor size (>5 cm) was significantly associated with recurrence (p = 0.03). Conclusions: HGD rectal polyps are associated with a significant risk of invasive cancer. Tumor size was a significant factor in predicting tumor recurrence in patients with postoperative HGD pathology. The TEM procedure is an effective first-line treatment for such lesions.

Abstract
BACKGROUND The most common technique for treating benign and early malignant rectal lesions is transanal endoscopic microsurgery (TEM). Local excision is an acceptable technique for high-risk and elderly patients, but there are hardly any data regarding young patients. AIM To describe TEM outcomes in patients under 50 years of age. METHODS We collected demographic, clinical, and pathological data from all patients under the age of 50 years who underwent the TEM procedure at Hasharon Rabin Medical Center from January 2005 to December 2018. RESULTS During the study period, a total of 26 patients under the age of 50 years underwent TEM procedures. Their mean age was 43.3 years. Eleven (42.0%) were male. The mean operative time was 67 min, and the mean tumor size was 2.39 cm, with a mean anal verge distance of 8.50 cm. No major intraoperative or postoperative complications were recorded. The median length of stay was 2 d. Seven (26.9%) lesions were adenomas with low-grade dysplasia, four (15.4%) were high-grade dysplasia adenomas, two were T1 carcinomas (7.8%), and three were T2 carcinomas (11.5%). No residual disease was found following endoscopic polypectomy in two patients (7.8%), but four (15.4%) had other pathologies. Surgical margins were negative in all cases. Local recurrence was detected in one patient 33 mo following surgery. CONCLUSION Among young adult patients, TEM for benign rectal lesions has excellent outcomes. It may also offer a balance between the efficacy of complete oncologic resection and postoperative quality of life in the treatment of rectal cancer. In some cases, it may be considered an alternative to radical surgery.

Management of the Rectal Stump after Subtotal Colectomy Operations for Inflammatory Bowel Disease in the Era of Immunologic Therapy: A Two-Centre Cohort Study. Dig Dis 2023; 41:872-878.

Abstract
INTRODUCTION Inflammatory bowel disease (IBD) often requires surgical resection, such as subtotal colectomy operations to alleviate symptoms. However, IBD also has an inherently increased risk of colorectal dysplasia and cancer. Despite the well-accepted surveillance guidelines for IBD patients with an intact colon, contemporaneous decision-making models on rectal stump surveillance is sparse. This study looks at the fate of rectal stumps in IBD patients following subtotal colectomy. METHODS This is a two-centre retrospective observational cohort study. Patients were identified from NHS Grampian and NHS Highland surgical IBD databases. Patients that had subtotal colectomy between January 01, 2010 and December 31, 2017 were included with the follow-up end date on April 1, 2021. Socio-demographics, diagnosis, medical and surgical management data were collected from electronic records. RESULTS Of 250 patients who had subtotal colectomy procedures, only one developed a cancer in their rectal stump (0.4%) over a median follow-up of 80 months. A higher than expected 72% of patients had ongoing symptoms from their rectal stumps. Surveillance was varied and inconsistent. However, no surveillance, flexible sigmoidoscopy, or MRI identified dysplastic or neoplastic disease. CONCLUSION Based on our results, we estimate that the prevalence of rectal cancer is lower than previously reported. Surveillance strategy of rectal stump varied as no current guidelines exist and hence is an important area for future study. Given the relatively low frequency of rectal cancer in these patients, and the low level of evidence available in this field, we would propose a registry-based approach to answering this important clinical question.

Abstract
PURPOSE In the treatment of early-stage rectal cancer, a growing number of studies have shown that transanal endoscopic microsurgery is one of the alternatives to radical surgery adhering to total mesorectal excision that can reduce the incidence of adverse events without compromising treatment outcomes. The purpose of this meta-analysis is to compare the safety and treatment effect of transanal endoscopic microsurgery and radical surgery adhering to total mesorectal excision to provide a basis for clinical treatment selections. METHOD We searched the literatures of four major databases, PubMed, Embase, Web of science, and Cochrane Library, without limitation of time. The literatures included randomized controlled studies and cohort studies comparing two surgical procedures of transanal endoscopic microsurgery and radical surgery adhering to total mesorectal excision. Treatment effectiveness and safety results of transanal endoscopic microsurgery and radical surgery were extracted from the included literatures and statistically analyzed using RevMan5.4 and stata17. RESULT Ultimately, 13 papers were included in the study including 5 randomized controlled studies and 8 cohort studies. The results of the meta-analysis showed that the treatment effect and safety of both transanal endoscopic microsurgery and radical surgery in distant metastasis (RR, 0.59 (0.34, 1.02), P > 0.05), overall recurrence (RR, 1.49 (0.96, 2.31), P > 0.05), disease-specific-survival (RR, 0.74 (0.09, 1.57), P > 0.05), dehiscence of the sutureline or anastomosis leakage (RR, 0.57 (0.30, 1.06), P > 0.05), postoperative bleeding (RR, 0.47 (0.22, 0.99), P > 0.05), and pneumonia (RR, 0.37, (0.10, 1.40), P > 0.05) were not significantly different. However, they differ significantly in perioperative mortality (RR, 0.26 (0.07, 0.93, P < 0.05)), local recurrence (RR, 2.51 (1.53, 4.21), P < 0.05),_overall survival_ (RR, 0.88 (0.74, 1.00), P < 0.05), disease-free-survival (RR, 1.08 (0.97, 1.19), P < 0.05), temporary stoma (RR, 0.05 (0.01, 0.20), P < 0.05), permanent stoma (RR, 0.16 (0.08, 0.33), P < 0.05), postoperative complications (RR, 0.35 (0.21, 0.59), P < 0.05), rectal pain (RR, 1.47 (1.11, 1.95), P < 0.05), operation time (RR, -97.14 (-115.81, -78.47), P < 0.05), blood loss (RR, -315.52 (-472.47, -158.57), P < 0.05), and time of hospitalization (RR, -8.82 (-10.38, -7.26), P < 0.05). CONCLUSION Transanal endoscopic microsurgery seems to be one of the alternatives to radical surgery for early-stage rectal cancer, but more high-quality clinical studies are needed to provide a reliable basis.

Abstract
Endoscopic resection has been widely applied especially in endoscopic submucosal dissection and third space endoscopy (TSE). Flexible endoluminal robotics allow performance of endoscopic submucosal dissection with exposure of the submucosal plane for precise dissection using two robotic arms. The introduction of TSE revolutionized the horizon of therapeutic endoscopy to the submucosal space beneath and beyond the mucosa. Advantages of TSE include avoidance of full thickness incision in gastrointestinal tract through the submucosal tunneling for performance of peroral endoscopic myotomy and submucosal tunneling endoscopic resection. In future, robotic-driven devices should be developed to enhance performance of complex endoluminal procedures and TSE.

Abstract
Introduction Local excision of large rectal polyps can be an alternative for radical rectal resection with total mesorectal excision. We aim to report the functional and oncological outcomes of transanal endoscopic microsurgery (TEM) for patients with large rectal polyps. Methods All demographic and clinical data of patients who underwent TEM for rectal polyp of 5 cm or more at the Hasharon Hospital from 2005 to 2018 were retrospectively reviewed. Results Twenty-eight patients were included. The mean age was 66 years. The mean polyp size was 6.2 cm (range: 5-8.5 cm) with a mean distance of 8.3 cm from the anal verge. Peritoneal entry during TEM was observed in five patients and additional laparoscopy after the completion of the TEM was performed in four patients. There were no major perioperative complications. Seven patients had minor complications. Final pathology revealed T1 carcinoma in five patients and T2 carcinoma in three patients. Re-TEM was performed in one patient with involved margins with adenoma. After a median follow-up of 64 months, one patient had local recurrence. Conclusion TEM is an acceptable technique for the treatment of large polyps with minor complications and a reasonable recurrence rate. TEM may be considered regardless of the size of the rectal polyp.

Abstract
Preoperative imaging of rectal carcinoma involves accurate assessment of the primary tumor as well as distant metastatic disease. Preoperative imaging of nonrectal colon cancer is most beneficial in identifying distant metastases, regardless of primary T or N stage. Surgical treatment remains the definitive treatment for colon cancer, while organ-sparing approach may be considered in some rectal cancer patients based on imaging obtained before and after neoadjuvant treatment. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
INTRODUCTION Local excision is increasingly used as an alternative treatment for radical surgery in patients with early stage clinical T1 (cT1) rectal cancer. This study provides an overview of incidence, staging accuracy and treatment strategies in patients with cT1 rectal cancer in the Netherlands. MATERIALS AND METHODS Patients with cT1 rectal cancer diagnosed between 2005 and 2018 were included from the Netherlands Cancer Registry. An overview per time period (2005-2009, 2010-2014 and 2015-2018) of the incidence and various treatment strategies used, e.g. local excision (LE) or major resection, with/without neoadjuvant treatment (NAT), were given and trends over time were analysed using the Chi Square for Trend test. In addition, accuracy of tumour staging was described, compared and analysed over time. RESULTS In total, 3033 patients with cT1 rectal cancer were diagnosed. The incidence of cT1 increased from 540 patients in 2005-2009 to 1643 patients in 2015-2018. There was a significant increased use of LE. In cT1N0/X patients, 9.2% received NAT, 25.5% were treated by total mesorectal excision (TME) and 11.4% received a completion TME (cTME) following prior LE. Overall accuracy in tumour staging (cT1 = pT1) was 77.3%, yet significantly worse in cN1/2 patients, as compared to cN0 patients (44.8% vs 77.9%, respectively, p < 0.001). CONCLUSION Over time, there was an increase in the incidence of cT1 tumours. Both the use of neoadjuvant therapy and TME surgery in clinically node negative patients decreased significantly. Clinical accuracy in T1 tumour staging improved over time, but remained significantly worse in clinical node positive patients.

Abstract
BACKGROUND The initial operation of choice in many patients presenting as an emergency with ulcerative colitis is a subtotal colectomy with end ileostomy. A percentage of patients do not proceed to completion proctectomy with ileal pouch anal anastomosis.
AIM To review the existing literature in relation to the significant long-term complic-ations associated with the rectal stump, to provide an overview of options for the surgical management of remnant rectum and anal canal and to form a consolidated guideline on endoscopic screening recommendations in this cohort.
METHODS A systematic review was carried out in accordance with PRISMA guidelines for papers containing recommendations for endoscopy surveillance in rectal remnants in ulcerative colitis. A secondary narrative review was carried out exploring the medical and surgical management options for the retained rectum.
RESULTS For rectal stump surveillance guidelines, 20% recommended an interval of 6 mo to a year, 50% recommended yearly surveillance 10% recommended 2 yearly surveillance and the remaining 30% recommended risk stratification of patients and different screening intervals based on this. All studies agreed surveillance should be carried out via endoscopy and biopsy. Increased vigilance is needed in endoscopy in these patients. Literature review revealed a number of options for surgical management of the remnant rectum.
CONCLUSION The retained rectal stump needs to be surveyed endoscopically according to risk stratification. Great care must be taken to avoid rectal perforation and pelvic sepsis at time of endoscopy. If completion proctectomy is indicated the authors favour removal of the anal canal using an intersphincteric dissection technique.

Abstract
AbstractTransanal endoscopic microsurgery is a minimally-invasive approach for rectal lesions. Superior exposure and access to the entire rectum result in lesser risk of compromised margins and lower recurrence rates, when compared to conventional transanal excision. The aim of this study was to describe a single institution's initial experience with transanal minimally invasive surgery (TAMIS). This was a prospective review of our database. Eleven procedures from January 2012 to June 2013 were analyzed.
Results eleven operations were completed. Five men were evaluated. Mean age was 62.9 (40-86). Mean follow-up was 9.3 (2-17) months. Average tumor size was 3.8 (1.8-8) cm. Mean distance from anal verge was 6.3 (3-12) cm. Mean operating time was 53.73 (28-118) min. Postoperative complication rate was 9.1%. There were no readmissions. Mortality was null. Operative pathology disclosed the presence of adenoma in four patients, invasive adenocarcinoma in two, neuroendocrine carcinoma in three, and no residual lesion in one case. TAMIS is a minimallyinvasive procedure with low postoperative morbidity at the initial experience. TAMIS is a curative procedure for benign lesions and for selected early cancers. It is useful after neoadjuvant therapy for strictly selected cancers, pending the results of multi-institutional trials.

Abstract
Introduction Although there have been important developments in microsurgery in recent years, there is no current and comprehensive bibliometric study in the literature. In this study, we aimed to present a summary of the articles published on microsurgery between 1980 and 2019 with bibliometric analysis. Methods Articles published on microsurgery between 1980 and 2019 were withdrawn from the Web of Science database and analyzed by bibliometric methods. Citation analysis was performed to identify effective journals and articles. Keyword cluster and trends analyses were performed for a detailed analysis of the researched topics. Relationships between the article numbers of the countries and gross domestic product (GDP) and human development index (HDI) values were investigated using Spearman’s correlation coefficient. A linear regression analysis was used to estimate the number of articles to be published in the future. Results A total of 3,537 publications related to microsurgery were found. Bibliometric analyses were performed in 2,063 articles (58.3%) of these publications. The most active countries in publishing were the United States (504), Germany (286), and Italy (154), respectively. A statistically significant correlation was found between the article numbers and the GDP and HDI sizes of the countries (r = 0.758, p <0.001, r = 0.659, p <0.001). Conclusion The economic size and development levels of the countries were an important factor in academic productivity in microsurgery. Undeveloped countries should be encouraged by performing multidisciplinary studies in this regard.

First clinical experience with single-port robotic transanal minimally invasive surgery (SP rTAMIS) for benign rectal neoplasms. Tech Coloproctol 2020; 25:117-124. [PMID: 33068190 DOI: 10.1007/s10151-020-02358-8] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Accepted: 10/06/2020] [Indexed: 01/11/2023]
Abstract
BACKGROUND The new da Vinci Single-Port (SP) robot is a single-arm four-channel robotic system well suited for endoluminal surgery. We report our initial experience performing SP robotic transanal minimally invasive surgery (SP rTAMIS) for rectal neoplasms. METHODS Under Institutional Review Board approval, two patients with rectal neoplasms were prospectively enrolled for elective SP rTAMIS. The primary endpoint was to report the safety and feasibility of successful procedure completion with the SP robot. Secondary endpoints included patient characteristics and perioperative metrics. RESULTS Both patients underwent successful SP rTAMIS resection of rectal neoplasms without intraoperative complications or conversions. The lesions were 4.0 cm and 3.0 cm in size, located 6 cm and 7 cm cephalad to the anorectal ring. Excisions were full thickness with no piecemeal extractions or specimen fragmentation. Estimated blood loss was 0 mL and 30 mL. The mean excised area was 13.4 cm2 (22.7 cm2 and 9.0 cm2). The mean docking time was 5.25 min (range 2-8 min) and mean console time was 122.5 min (98 min and 147 min). Patients tolerated a liquid diet on postoperative day (POD) 0 and were discharged on POD 1 after tolerating a low residue diet and having bowel function. Pathology showed two adenomas with negative margins. There was no immediate or delayed morbidity or mortality. CONCLUSIONS Our initial experience indicates that SP rTAMIS is a safe and feasible approach for local excision of rectal lesions. While SP rTAMIS is very promising, more experience with this approach is necessary to determine its widespread applicability.

Abstract
BACKGROUND Transanal excision is the surgical treatment of choice for low-risk rectal pathology such as endoscopically unresectable polyps, very select early rectal cancers, as well as other benign and low-risk tumors. Robotic transanal minimally invasive surgery enhances the surgeon's ability to work in the confined space of the rectum and helps overcome the limitations of other modalities for transanal excision. Large lesions that extend to the dentate line and cannot be excised transanally impart a particular challenge. Herein, we describe a hybrid robotic transanal minimally invasive surgery approach for excising large rectal lesions that extend to the dentate line and cannot be excised by utilizing traditional transanal techniques. TECHNIQUE With the use of a standard transanal approach, the distal margin of the lesion is marked and lifted off of the internal sphincter muscle. The dissection is continued until above the anorectal ring, and a 5.5-cm transanal platform is introduced transanally. Insufflation with an 8-mm trocar is initiated and the robotic platform is docked transanally. A 1-cm circumferential proximal margin is marked, and the excision is continued robotically until en bloc resection of the lesion is completed. The defect is closed in a transverse fashion using barbed suture. For rare cases of circumferential or nearly circumferential full-thickness defects, interrupted barbed sutures are placed equidistant, the robot is undocked, the transanal platform is removed, and a handsewn coloanal anastomosis is performed allowing complete closure of the defect. RESULTS A hybrid robotic transanal minimally invasive surgery approach to large and low-lying rectal lesions is feasible and safe, and it has advantages over standard transanal excision including enhanced ergonomics, dexterity, and optics, as well as reduced rates of specimen fragmentation. CONCLUSION A hybrid robotic transanal minimally invasive surgery approach allows for complete resection of very large polyps, which would otherwise be extremely challenging with standard transanal approaches.

Abstract
This Editorial presents a new Special Issue dedicated to some old and new interdisciplinary areas of cooperation between engineering and surgery. The first two sections offer some food for thought, in terms of a brief introductory and general review of the past, present, future and visionary perspectives of the synergy between engineering and surgery. The last section presents a very short and reasoned review of the contributions that have been included in the present Special Issue. Given the vastness of the topic that this Special Issue deals with, we hope that our effort may have offered a stimulus, albeit small, to the development of cooperation between engineering and surgery.

Abstract
A dynamic evolution is occurring in transanal surgery. Transanal techniques began with intraluminal surgical removal of rectal masses and have progressed to transanal total mesorectal excision (taTME) for rectal cancer. TaTME was first performed in 2009 by Sylla, Rattner, Delgado, and Lacy. This article documents the training pathway followed by pioneers in the taTME technique as well as consensus reports outlining the process of learning the taTME technique. A literature search was performed for taTME training, learning, and technique. Key elements in learning the taTME technique include appropriate indications, cadaver training, and outcomes reporting such as participating in a taTME registry. Consensus reports also agree on the following facets associated with improved outcomes: (1) appropriate case selection of mid and low rectal cancers, (2) prerequisite completion of an accredited training program in laparoscopic colorectal surgery and prior experience in transanal endoscopic surgery, (3) a two-team taTME approach from above and below is ideal, and (4) higher rectal cancer volume surgical practice. The unifying international recommendation for surgeons interested in learning the taTME technique conveys the following message: taTME is an advanced and complex technique that requires dedicated training and experience in TME surgery.

Abstract
PURPOSE The study aimed to evaluate the feasibility and safety of a new trans-anal rectoscopic-assisted minimally invasive surgery (ARAMIS) platform to treat rectal lesions. METHODS ARAMIS was first compared with two transanal minimally invasive surgery platforms (SILS Port and GelPOINT Path) on human cadavers. Surgeons with different experience performed running sutures at different distances, at four quadrants, using the three platforms and gave a score to visibility, safety, and maneuverability. ARAMIS was then utilized on patients affected with rectal neoplasia who met the inclusion criteria. Patients and tumor characteristic and results were prospectively collected. The follow-up examinations included proctoscopy at 3, 6, and 12 months. RESULTS According to surgeons' scores, ARAMIS improves visibility and safety with respect to other platforms for distances beyond 10 cm. The procedure, which lasted an average of 59 min, was successfully carried out in 14 patients. No intraoperative or postoperative complications were reported. The mean tumor size was 3 cm; they were located a mean of 11 cm from the anal verge. Complete removal of the lesion was possible in 13/14 patients. There was one case of adenoma recurrence at follow-up. CONCLUSION Study results showed that ARAMIS, which is equipped with an adjustable rectoscope, can be considered a safe, effective platform for transanal surgery. The rectoscope protects the rectum during the procedure, a particularly important consideration when proximal rectal lesions are being treated. Further clinical studies are warranted to confirm these encouraging results.

Abstract
BACKGROUND Local excision of T1 rectal cancers helps avoid major surgery, but the frequency and pattern of recurrence may be different than for patients treated with total mesorectal excision. OBJECTIVE This study aims to evaluate pattern, frequency, and means of detection of recurrence in a closely followed cohort of patients with locally excised T1 rectal cancer. DESIGN This study is a retrospective review. SETTINGS Patients treated by University of Minnesota-affiliated physicians, 1994 to 2014, were selected. PATIENTS Patients had pathologically confirmed T1 rectal cancer treated with local excision and had at least 3 months of follow-up. INTERVENTIONS Patients underwent local excision of T1 rectal cancer, followed by multimodality follow-up with physical examination, CEA, CT, endorectal ultrasound, and proctoscopy. MAIN OUTCOME MEASURES The primary outcomes measured were the presence of local recurrence and the means of detection of recurrence. RESULTS A total of 114 patients met the inclusion criteria. The local recurrence rate was 11.4%, and the rate of distant metastasis was 2.6%. Local recurrences occurred up to 7 years after local excision. Of the 14 patients with recurrence, 10 of the recurrences were found by ultrasound and/or proctoscopy rather than by traditional methods of surveillance such as CEA or imaging. Of these 10 patients, 4 had an apparent scar on proctoscopy, and ultrasound alone revealed findings concerning for recurrent malignancy. One had recurrent malignancy demonstrated on ultrasound, but no concurrent proctoscopy was performed. LIMITATIONS This was a retrospective review, and the study was conducted at an institution where endorectal ultrasound is readily available. CONCLUSIONS Locally excised T1 rectal cancers should have specific surveillance guidelines distinct from stage I cancers treated with total mesorectal excision. These guidelines should incorporate a method of local surveillance that should be extended beyond the traditional 5-year interval of surveillance. An ultrasound or MRI in addition to or instead of flexible sigmoidoscopy or proctoscopy should also be strongly considered. See Video Abstract at http://links.lww.com/DCR/A979.

OBJETIVO Evaluar el patrón, la frecuencia y los medios de detección de recidiva en una cohorte de pacientes con cáncer de recto T1 extirpado localmente bajo un régimen de seguimiento especifico. DISEÑO:: Revisión retrospectiva. AJUSTES Pacientes tratados por hospitales afiliados a la Universidad de Minnesota, 1994-2014 PACIENTES:: Pacientes con cáncer de recto T1 confirmado patológicamente, tratados con escisión local y con al menos 3 meses de seguimiento. INTERVENCIONES Extirpación local del cáncer de recto T1, con un seguimiento multimodal incluyendo examen físico, antígeno carcinoembrionario (CEA), TC, ecografía endorrectal y proctoscopia. PRINCIPALES MEDIDAS DE RESULTADO Presencia de recurrencia local y medios de detección de recurrencia. RESULTADOS Un total de 114 pacientes cumplieron con los criterios de inclusión. La tasa de recurrencia local fue del 11,4% y la tasa de metástasis a distancia fue del 2,6%. Las recurrencias locales se presentaron hasta 7 años después de la escisión local. De los 14 pacientes con recurrencia, 10 de las recurrencias se detectaron por ultrasonido y / o proctoscopia en lugar de los métodos tradicionales de vigilancia, como CEA o imágenes. De estos diez pacientes, cuatro tenían una cicatriz aparente en la proctoscopia y el ultrasonido solo reveló hallazgos relacionados con tumores malignos recurrentes. En una ecografía se demostró malignidad recurrente, pero no se realizó proctoscopia concurrente. LIMITACIONES Revisión retrospectiva; estudio realizado en una institución donde se dispone fácilmente de ultrasonido endorrectal CONCLUSIONES:: Los cánceres de recto T1 extirpados localmente deben tener una vigilancia específica distinta de los cánceres en etapa I tratados con TME. El régimen de seguimiento deberá de extender más allá del intervalo tradicional de 5 años de vigilancia. También se debe considerar la posibilidad de realizar una ecografía o una resonancia magnética (IRM) además de la sigmoidoscopía flexible o la proctoscopía.

Abstract
OBJECTIVE This study describes the outcomes for 200 consecutive transanal minimally invasive surgery (TAMIS) local excision (LE) for rectal neoplasia. BACKGROUND TAMIS is an advanced transanal platform that can result in high quality LE of rectal neoplasia. METHODS Consecutive patients from July 1, 2009 to December 31, 2015 from a prospective institutional registry were analyzed. Indication for TAMIS LE was endoscopically unresectable benign lesions or histologically favorable early rectal cancers. The primary endpoints were resection quality, neoplasia recurrence, and oncologic outcomes. Kaplan-Meier survival analyses were used to describe disease-free survival (DFS) for patients with rectal adenocarcinoma that did not receive immediate salvage radical surgery. RESULTS There were 200 elective TAMIS LE procedures performed in 196 patients for 90 benign and 110 malignant lesions. Overall, a 7% margin positivity and 5% fragmentation rate was observed. The mean operative time for TAMIS was 69.5 minutes (SD 37.9). Postoperative morbidity was recorded in 11% of patients, with hemorrhage (9%), urinary retention (4%), and scrotal or subcutaneous emphysema (3%) being the most common. The mean follow up was 14.4 months (SD 17.4). Local recurrence occurred in 6%, and distant organ metastasis was noted in 2%. Mean time to local recurrence for malignancy was 16.9 months (SD 13.2). Cumulative DFS for patients with rectal adenocarcinoma was 96%, 93%, and 84% at 1-, 2-, and 3-years. CONCLUSIONS For carefully selected patients, TAMIS for local excision of rectal neoplasia is a valid option with low morbidity that maintains the advantages of organ preservation.

Abstract
BACKGROUND Transanal endoscopic microsurgery (TEM) is the treatment of choice for benign rectal tumors and select early rectal cancers. This surgical approach has become ubiquitous and surgeons are seeing recurrent lesions after TEM resection. This study aims to outline the safety and outcomes of repeat TEM when compared to primary TEM procedures. METHODS At St. Paul's Hospital, demographic, surgical, pathologic, and follow-up data for patients treated by TEM are maintained in a prospectively populated database. Two groups were established for comparison: patients undergoing first TEM procedure (TEM-P) and patients undergoing repeat TEM procedure (TEM-R). RESULTS Between 2007 and 2017, 669 patients had their first TEM procedure. Over this time frame, 57 of these patients required repeat TEM procedures, including 15 of these patients treated by 3 or more TEMs. Indications for repeat TEM included recurrence (78%), positive margins (15%), and metachronous lesions (7%). There were no differences between the groups in patient age, gender, or tumor histology. Compared to TEM-P, TEM-R had shorter operative times (38 vs. 52 min, p < 0.001), more distal lesions (5 vs. 7 cm, p < 0.004), and smaller lesions (3 vs. 4 cm, p < 0.0003). The TEM-R group had similar length of hospital stay (0.45 vs. 0.56 days, p = 0.65), rates of clear margins on pathology (81% vs. 88%, p = 0.09), and 30-day readmission rates (7% vs. 4%, p = 0.27) when compared to TEM-P group. TEM-R was more likely to be managed without suturing the surgical defect (72% vs. 32%, p < 0.0001). Repeat TEM was associated with similar post-operative complications as primary TEM graded on the Clavien-Dindo classification scale (Grade 1: 5% vs. 5%, Grade 2: 5% vs. 4%, Grade 3: 5% vs. 1%, p = 0.53). No 30-day mortality occurred in either group. CONCLUSIONS The St. Paul's Hospital TEM experience suggests repeat TEM is a safe and feasible procedure with similar outcomes as patients undergoing first TEM.

Abstract
Introduction Transanal endoscopic microsurgery (TEM) is a minimally invasive procedure which allows local excision of early-stage rectal cancer and can be used as an alternative treatment to radical surgery. Patients can undergo salvage total mesorectal excision (sTME) following TEM after finding of unfavourable histological features. This study aimed to compare results and possible complications of sTME following TEM and primary TME (pTME) procedures. Methods Between 2010 and 2017, early sTME was performed in 9 patients at the National Cancer Institute in Vilnius, Lithuania. These patients were compared with 18 patients who underwent pTME, matched according to gender, age, cancer stage, and operative procedure. Data were obtained from the patients' charts and reviewed prospectively. We recorded the demographics, tumour specifications, treatment, operation time, postoperative results complications, and oncological outcome. Fisher's exact test and student's T test was used to compare both groups. Results A total of 130 patients underwent TEM at our institution during the study period, of which 9 (6.92%) had to undergo sTME. The average age of the patients was 62.7 ± 7.07 years; 44.4% of the patients were male and 55.6% female. The average tumour size in the sTME group was 2.8 ± 1.05 cm (range 1.5-5) and 2.61 ± 1.36 cm (range 1-5) in the pTME group (p = 0.696). When comparing postoperative complications, statistically significant results were not found in either of the groups (p = 0.55). Operation time of pTME was significantly shorter on average, i.e. 43 min, compared to sTME (p < 0.0267). The average number of harvested lymph nodes was 12.44 ± 7.126 in the sTME and 12.5 ± 8.06 in the pTME group (p = 0.986). The circumferential resection margin (CRM) was negative in 92.6% (25/27) of specimens, while the CRM was positive in 2 cases (7.4%), both of which were from the sTME group. The average follow-up time was 22.8 months (8-80 months) for patients undergoing sTME and 19.33 months (2-88 months) for patients after pTME (p = 0.71). Conclusions TEM is a relatively safe method for treating patients with early rectal cancer without high-risk features. It can be used in exceptional cases with high-risk features when the patient is not fit for radical surgery.

Abstract
Transluminal surgery, also known as natural orifices endoluminal surgery, can be considered the most minimally invasive approach of gaining access to an organ. Although some approaches, such as transgastric or transvaginal cholecystectomy, have remained experimental, peroral endoscopic myotomy to treat achalasia and transanal total mesorectal excision to treat low rectal cancer have become accepted, safe, and feasible approaches by trained surgeons for selected patients. This article recapitulates the development of transluminal surgery from its experimental beginnings to the validated procedure it has become today.

Abstract
BACKGROUND Robotic technology aims to obviate some of the limitations of conventional laparoscopic surgery, yet the role of robotics in colorectal surgery is still largely undefined and varies with respect to its application in abdominal versus pelvic surgery. METHODS With this review, we aimed to highlight current developments in colorectal robotic surgery. We systematically searched the following databases: PubMed, EMBASE, and Cochrane Library. We critically reviewed the available literature on the use of robotic technology in colon and rectal surgery. RESULTS Robotic colorectal surgery is oncologically safe and has short-term outcomes comparable to conventional laparoscopy, with potential benefits in rectal surgery. It has a shorter learning curve but increased operative times and costs. It offers potential advantages in the resection of rectal cancer, due to lower conversion rates. There is also a trend toward better outcomes in anastomotic leak rates, circumferential margin positivity, and perseveration of autonomic function. CONCLUSION Laparoscopy remains technically challenging and conversion rates are still high. Therefore, most cases of colorectal surgery are still performed open. Robotic surgery aims to overcome the limits of the laparoscopic technique. This new technology has many advantages in terms of articulating instruments, advanced three-dimensional optics, surgeon ergonomics, and improved accessibility to narrow spaces, such as the pelvis. However, further studies are needed to assess long-term results and benefits.

Abstract
In the treatment of colorectal cancer, total mesorectal excision (TME) has risen as the gold standard in the surgical treatment of this disease in order to obtain negative distal and circumferential radial margins. Since introduction in 2010, transanal TME has aimed to decrease the rate of positive margins and improve the quality of the dissection while decreasing the complications associated with a transabdominal low pelvic dissection. We retrospectively reviewed 25 cases of transanal TME completed between December 2014 and August 2017. Most of the patients in our case series were male (60%) with an average age of 57.1 years, BMI of 28.4 kg/m2, and with an American Society of Anesthesiologists score of II. The average tumor was midrectal (about 5.9 cm from the anal verge), clinically T3-T4 (92%), and had undergone neoadjuvant therapy (96%). The average operation was about six hours and 44 minutes with ileostomy placed most of the time (92%). In all the cases where the TME quality was graded, the specimens were reported to have been complete (grade I). There were no positive distal, radial, or proximal margins. The average hospital stay was about 5.9 days. The rate of minor complications was about 48 per cent and major complications occurred about 16 per cent of the time.

Peritoneal perforation during transanal endoscopic microsurgery is not associated with significant short-term complications. Surg Endosc 2018; 33:849-853. [PMID: 30022287 DOI: 10.1007/s00464-018-6351-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2017] [Accepted: 07/06/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND In patients treated by transanal endoscopic microsurgery (TEM), breach of the peritoneal cavity is a feared intraoperative challenge. Our aim is to analyze predictors and short-term outcomes of patients with peritoneal perforation (TEM-P) when compared to similar patients with no peritoneal compromise (TEM-N). METHODS At St. Paul's Hospital, demographic, surgical, pathologic, and follow-up data for all patients treated by TEM is maintained in a prospectively populated database. A retrospective review was performed and two groups were established for comparison: TEM-P and TEM-N. Statistical analysis was performed using student's t or chi-squared test, where appropriate. RESULTS Of 619 patients treated by TEM between 2007 and 2016, 39 (6%) patients were in the TEM-P group and 580 (94%) in the TEM-N group. There were no differences between the groups in patient age, gender, histology, or tumor size. Patients who had peritoneal perforations had more proximal lesions (11 vs. 7 cm, p < 0.0001), anterior lesions (56 vs. 43%, p < 0.05), and longer operations (80 vs. 51 min, p < 0.005). While most defects were closed endoluminally, 2 patients with perforation were converted to transabdominal surgery. There was a difference in overall hospital stay with TEM-P patients staying on average 2 days in hospital with fewer patients managed as day surgery (31 vs. 73%, p < 0.0001). There were no mortalities or significant 30-day complications in the TEM-P group and only one patient required readmission. CONCLUSIONS The St. Paul's Hospital TEM experience suggests patients with peritoneal breach during TEM can be safely managed with outcomes similar to patients without peritoneal entry. Proximal, anterior lesions are at highest risk of peritoneal perforation.

Abstract
BACKGROUND Transanal minimally invasive surgery (TAMIS) offers intra-luminal full-thickness excision of rectal neoplasia. Robotic TAMIS (RT) allows for greater versatility in motion while operating in the limited space of the rectum. We present our experience with this technique in practice using the DaVinci Xi™ platform. METHOD This is a multi-institutional retrospective analysis for patient undergoing Robotic TAMIS for resection of rectal lesions at two tertiary referral hospitals in the United States. Morbidity, mortality, anatomic measurement, and final pathology were analyzed. RESULTS Thirty-four patients planned for Robotic TAMIS were identified. Average follow-up was 188 days. The average BMI was 29.5 ± 5.9. All patients had an American Society of Anesthesiologist (ASA) Class of 2 or greater and 21 (62%) were ASA 3 or greater. Rectal lesions located from 2 to 15 cm from the dentate line were successfully resected. Lesions up to 4.5 cm in the longest dimension were successfully resected. The average operative time was 100 ± 70 min, which correlated to a robotic console time of 76 ± 67 min. Patients were placed in Lithotomy in 32 (94%) cases and were prone in only 2 (6%) cases. There were no intraoperative complications or conversions to another technique. The only postoperative complication was a medically managed Clostridium difficile infection in 1 patient. Three patients were upstaged to T2 on final pathology and underwent successful formal resections. BMI was a statistically significant predictor of a longer operation. CONCLUSIONS With increased reach and operative range of motion, Robotic TAMIS is a safe and effective method for excising low-risk rectal neoplasia with a wide range of anatomical measurements. Higher BMI is a significant predictor of a longer and likely more challenging operation.

Abstract
BACKGROUND Patients' selection for transanal endoscopic microsurgery (TEM) depends on diagnostic modalities; however, there are still some limitations in the preoperative diagnosis of rectal lesions, and in some reports, up to third of the adenomas resected by TEM were found to be adenocarcinoma; therefore, salvage radical resection (RR) remains necessary for achieving oncological resection. Salvage RR may encounter some technical problems as the violation of the mesorectum and the scar formation. In this study, we aimed to report the outcome in patients undergoing salvage RR in terms of morbidity and oncological results. MATERIALS AND METHODS Demographic and clinical data pertaining to patients undergoing RR following TEM between 2004 and 2014 were retrospectively collected. RESULTS One hundred forty one TEM were performed in the study period, 53 (38%) for malignant rectal lesions. Indication for TEM: 15 (28%) benign adenoma, 25 (47%) early rectal cancer, and 13 (25%) had clinical complete response after neoadjuvant radiochemotherapy. Ten (19%) patients had no residual tumor in TEM specimen, 15 (28%) had T1, and 2 of them underwent salvage low anterior resection (LAR). Ten (19%) had T2, 4 had LAR, and 1 had abdominoperineal resection (APR). Five (9%) had a T3, 3 underwent LAR, and 2 had APR. Among the 13 (25%) after chemo-radiotherapy (CRT), 4 had salvage AR. The time from TEM to RR was 47 days (range32-70). Of 16 salvage surgeries, 8 (50%) were laparoscopic. The median operative time was 210 minutes (range165-360). Five patients had protective ileostomy. Rectal perforation occurred in 2 (12%) patients; both had a posterior location, one after CRT. Two (12%) postoperative small-bowl obstruction and three wound infections occurred. There was no perioperative mortality in any of the patients who underwent RR. The final pathology was no residual disease in 9, T3N1 in 1, T3N0 in 3, T2N1 in 1, and T2N0 in 2 patients. Eight (50%) had adjuvant chemotherapy. CONCLUSION Laparoscopic total mesorectal excision following TEM seems to be safe, and with no negative impact of the completeness of the resection. The concern of intraoperative specimen perforation is real, and should be dealt with meticulous technique and careful dissection, particularly after CRT.

Abstract
Colorectal cancers are common tumors in the United States and appropriate imaging is essential to direct appropriate care. Staging and treatment differs between tumors arising in the colon versus the rectum. Local staging for colon cancer is less integral to directing therapy given radical resection is often standard. Surgical options for rectal carcinoma are more varied and rely on accurate assessment of the sphincter, circumferential resection margins, and peritoneal reflection. These important anatomic landmarks are best appreciated on high-resolution imaging with transrectal ultrasound or MRI. When metastatic disease is suspected, imaging modalities that provide a global view of the body, such as CT with contrast or PET/CT may be indicated. Rectal cancer often metastasizes to the liver and so MRI of the liver with and without contrast provides accurate staging for liver metastases. This article focuses on local and distant staging and reviews the appropriateness of different imaging for both variants. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
Radical surgery is considered as the standard treatment for rectal cancer. Transanal local excision has been considered an interesting alternative for the management of selected patients with rectal cancers for many decades. Different approaches had been considered for local excision, from endoscopic submucosal dissection to resections using platforms, such as transanal endoscopic microsurgery or transanal minimally invasive surgery. Identifying the ideal candidate for this approach is crucial, as a local failure after local excision is associated with poor outcomes, even for an initial early rectal tumor. In this article, the diagnostic tools and criteria to select patients for local excision, the different modalities used, and the outcomes are discussed.

Abstract
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. Distant metastasis and overall and cancer-specific survival were determined. RESULTS LR developed in 14 patients; in 2/4 with R1/X resection, in 3/8 (38%) with clear margins (R0) but a minimal distance of ≤1 mm, and in 9/88 (10%) with formally complete resection. Six of nine patients with formally complete resection underwent radical surgery for LR; in five out of these six, lymph nodes were not involved. In 5/14 patients, LR was poorly differentiated compared to primary carcinoma. Main LR causes were incomplete tumor resection or tumor persistence after formally complete resection. Overall (p = 0.008) and cancer-specific (p < 0.001) survival was lower in LR patients compared to non-LR patients, even if lymph nodes were uninvolved. CONCLUSIONS The results suggest that most LRs after TEM for low-risk rectal cancer were caused by residual tumor at the previous excision site and not by undetected lymph node metastases. By improved standardization of surgical techniques to ensure complete resection of carcinomas and thorough pathological assessments, most LRs seem to be avoidable.

Abstract
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. In this study, we aimed to report the outcome of patients with SCRT treated by laparoscopic colectomy combined with Transanal Endoscopic Microsurgery. METHODS Data pertaining patients undergoing combined colectomy and Transanal Endoscopic Microsurgery (TEM) between 2004 and 2014 were retrospectively collected. RESULTS 141 TEM performed in the study period, 9 (6.5%) with combined laparoscopic colectomy were included. Mean age was 69.1 ± 10.6 years. There were 6 (66%) right, 2 (22%) left, and one (11%) sigmoid colectomy. All rectal lesions were benign adenomas, with mean tumor size 2.5 cm, and distance from the verge 9 ± 2.5 cm. Lesions were located in lateral rectal wall in 4, posterior in 4, and anterior in one case. Seven patients had the colectomy before TEM, and 2 had the TEM first. Mean operative time was 245 minutes (range 185-313) for the combined procedures. Median time of hospitalization was 6 days (range 4-11). Six patients (66%) had prolonged postoperative diarrhea. The final rectal pathology reports were adenoma with high-grade dysplasia (HGD) in 5 patients and adenoma with low-grade dysplasia in four cases. The colon pathology was T1 N0 in 3, T2 N0 in one, T3 N1 in one, adenoma with HGD in 2, and no residual tumor in 2 patients. Two patients underwent re-TEM for recurrent adenoma of rectum at 14 and 18 months postoperatively. CONCLUSION The combination of TEM with laparoscopic colectomy is feasible and should be kept in mind as an alternative procedure in case of SCRT. However, more strict selection criteria should be considered and the disadvantages should be discussed with the patient.

Abstract
Transanal excision (TAE) for rectal tumors is increasingly applied and it is generally recommended that the defect following full-thickness excision should be closed. The aim of this study was to compare the complications and anal function following TAE between cases where the defect was closed and those where it was not. A total of 43 consecutive rectal malignant tumor patients eligible for TAE were investigated. Regarding anorectal function, incontinence was assessed using the Wexner score. The defect of the rectum was closed in 21 of the 43 patients. There were no significant differences between the two groups regarding gender, distance from the anal verge, tumor size, diagnosis and tumor site. There was a significantly higher number of postoperative complications of all grades and ≥Clavien-Dindo grade IIIa in the closure group (P=0.02 and 0.04, respectively). Regarding the Wexner score, there was no significant difference between the two groups (P=0.24). Compared with the closure group, the non-closure group had significantly fewer postoperative complications of all grades and ≥Clavien-Dindo grade IIIa. Moreover, there was no significant difference regarding the anorectal function between the two groups. Thus, suturing the rectal defect is not necessarily recommended following TAE.

Abstract
PURPOSE Transanal endoscopic microsurgery (TEM) is a safe and efficient minimally invasive treatment for rectal benign and early malignant neoplasia, but postoperative complications may be severe. We aimed to evaluate the risk factors related to the incidence, severity, and time course of postoperative complications of TEM. METHODS This is a prospective study of postoperative complications in 53 patients (>18 years old) with benign or early rectal neoplasia who underwent TEM with curative intention or, for higher stages, palliation. Outcome measures included age, sex, American Society of Anesthesiologists score, neoadjuvant chemoradiotherapy, lesion height and size, pathologic margins, tumor histology, and suture type. RESULTS Overall morbidity was 50 %. Temporary fecal incontinence was the most frequent complication (17.3 %). Complication rates of Clavien-Dindo grades I and II were 21.1 % and those of grades III and IV 3.8 %. Of patients with complications, more had lesions under the first rectal valve than over the first valve (61.54 % vs 38.46 %, p = 0.04). Patients submitted to chemoradiotherapy had a 24-fold greater chance of presenting grade II complications (p = 0.002). When the surgical defect was treated using the TEM device to perform the suture, the chance of having grade III complications was reduced 16-fold (p = 0.04). Fifty-three percent of complications occurred in the first 10 days and 95 % within 20 days. CONCLUSIONS Postoperative complications after transanal endoscopic microsurgery for the treatment of rectal neoplasia are frequent, acceptable, and usually controllable with pharmacologic treatment. Over time the nature of complications is continuous, centered on the first 20 days after surgery.

Abstract
The treatment for rectal cancer and benign rectal lesions continues to progress in the arena of minimally invasive surgery. While surgical excision of the primary mass remains essential for eradication of disease, there has been a paradigm shift towards less invasive resection methods. Local excision is increasing in popularity for its low morbidity and excellent functional results in select patients. Transanal minimally invasive surgery (TAMIS) is a new technology developed to elevate the practice of local excision to state-of-the-art resection. The goal of this article is to evaluate the history, short-term outcomes, and evolution of the TAMIS technique for excision of benign and malignant rectal neoplasia.

Abstract
Over the last few years, endoscopic submucosal dissection (ESD) has shown to be effective in the management of early colorectal neoplasms, particularly in Asian countries where the technique was born. In the Western world, its implementation has been slow and laborious. In this paper, the indications for ESD, its learning model, the available methods to predict the presence of deep submucosal invasion before the procedure and the published outcomes from Asia and Europe will be reviewed. Since ESD has several limitations in terms of learning achievement in the West, and completion of the procedure for the first cases is difficult in our part of the world, a short review on colorectal assisted ESD has been included. Finally, other endoscopic and surgical treatment modalities that are in competition with colorectal ESD will be summarized.

Abstract
BACKGROUND Transanal endoscopic microsurgery is superior to other methods of local excision of rectal cancer, but few studies report long-term follow-up data. OBJECTIVE This study investigated the use of transanal endoscopic microsurgery alone as curative and compromise therapy based on long-term disease recurrence and mortality. DESIGN This was a retrospective review of prospectively collected data. SETTINGS The study was conducted at a tertiary care university medical center. PATIENTS The study included 133 patients treated between 1985 and 2007. There were 3 groups, including transanal endoscopic microsurgery in curative intent (low-risk rectal carcinoma, including pT1, G1/2, L0, and LX with clear margins and a minimal distance between tumor and resection margin of >1 mm (N = 64) or clear margins only (N = 18 ))) and as compromise therapy (high-risk or incompletely resected rectal carcinoma; N = 51). MAIN OUTCOME MEASURES Log-rank tests were used to compare overall and cancer-specific survival. RESULTS The median follow-up time was 8.6 years (range, 0.2-25.1 years), and a total of 131 of 133 patients (98.5%) were followed >5 years or until death. The preoperative diagnosis of carcinoma was not associated with belonging into 1 of the 3 categories. In patients with low-risk completely (>1 mm) resected carcinoma, the 5- and 10-year local recurrence rates were 6.6% and 11.6%. In patients with high-risk or incompletely resected carcinoma, the rates were 32.5% and 35.0% (p = 0.006). The 5- and 10-year cancer-specific survival rates for low-risk patients were 98.0% and 91.0% and 84.3% and 74.3% for high-risk patients (p = 0.05). LIMITATIONS The study was limited by its retrospective design and small subgroups. CONCLUSIONS The high cancer-specific survival justifies transanal endoscopic microsurgery alone as curative treatment in low-risk rectal carcinoma. Complete resection is essential to lower the risk of local recurrence. The high local recurrence rate in patients with high-risk rectal carcinoma restricts the use of TEM alone as compromise therapy.

Abstract
BACKGROUND With increasing interest in natural orifice surgery, there has been a dramatic evolution of transanal and endoluminal surgical techniques. These techniques began with transanal endoluminal surgical removal of rectal masses and have progressed to transanal radical proctectomy for rectal cancer. The first transanal total mesorectal excision (taTME) was performed in 2009 by Sylla, Rattner, Delgado, and Lacy. The improved visibility and working space associated with the taTME technique is intriguing. This video manuscript outlines the training pathway followed by pioneers in the taTME technique, the process of implementation into clinical practice, and initial case report. METHODS A double board-certified colorectal surgeon with expertise in rectal cancer, minimally invasive total mesorectal excision, transanal endoscopic surgery (TES), and intersphincteric dissection, underwent taTME training in male cadaver models. Institutional review board (IRB) approval for a phase I clinical trial was achieved. The entire operative team including surgeons, nurses, and operative staff underwent taTME cadaver training the day prior to the first clinical case. The case was proctored by an expert in taTME. RESULTS A 66-year-old male with uT3N1M0 rectal cancer located in the posterior distal rectum, underwent taTME with laparoscopic abdominal assistance, hand sewn coloanal anastomosis, and diverting loop ileostomy. The majority of the TME was performed transanally with laparoscopic assistance for exposure, splenic flexure mobilization, and high ligation of the vascular pedicles. Operative time was 359 min. There were no intraoperative complications. Pathology revealed a ypT2N1 moderately differentiated invasive adenocarcinoma, grade I TME, 1 cm circumferential radial margin, and 2/13 positive lymph nodes. CONCLUSION Implementation of taTME into practice can be achieved by surgeons with expertise in minimally invasive TME, TES, pre-clinical taTME training in cadavers, case observation, proctoring, and ongoing mentorship. IRB peer review process and participation in a clinical registry are additional measures that should be employed.

Abstract
These guidelines provide an evidence-based framework for the management of patients with large non-pedunculated colorectal polyps (LNPCPs), in addition to identifying key performance indicators (KPIs) that permit the audit of quality outcomes. These are areas not previously covered by British Society of Gastroenterology (BSG) Guidelines.A National Institute of Health and Care Excellence (NICE) compliant BSG guideline development process was used throughout and the Appraisal of Guidelines for Research and Evaluation (AGREE II) tool was used to structure the guideline development process. A systematic review of literature was conducted for English language articles up to May 2014 concerning the assessment and management of LNPCPs. Quality of evaluated studies was assessed using the Scottish Intercollegiate Guidelines Network (SIGN) Methodology Checklist System. Proposed recommendation statements were evaluated by each member of the Guideline Development Group (GDG) on a scale from 1 (strongly agree) to 5 (strongly disagree) with >80% agreement required for consensus to be reached. Where consensus was not reached a modified Delphi process was used to re-evaluate and modify proposed statements until consensus was reached or the statement discarded. A round table meeting was subsequently held to finalise recommendations and to evaluate the strength of evidence discussed. The GRADE tool was used to assess the strength of evidence and strength of recommendation for finalised statements.KPIs, a training framework and potential research questions for the management of LNPCPs were also developed. It is hoped that these guidelines will improve the assessment and management of LNPCPs.

Abstract
BACKGROUND: Transanal endoscopic microsurgery is a minimally invasive technique that allows full-thickness resection and suture closure of the defect for large rectal adenomas, selected low-risk rectal cancers, or small cancers in patients who have a high risk for major surgery. Our aim, in the given prospective study was to report our initial clinical experience with TAMIS, and to evaluate its effects on postoperative anorectal functions. MATERIALS AND METHODS: In 10 patients treated with TAMIS for benign and malignant rectal tumors, preoperative and postoperative anorectal function was evaluated with anorectal manometry and Cleveland Clinic Incontinence Score. RESULTS: The mean distance of the tumors from the anal verge was 5.6 cm, and mean tumor diameter was 2.6 cm. All resection margins were tumor free. There was no difference in preoperative and 3-week postoperative anorectalmanometry findings; only mean minimum rectal sensory volume was lower at 3 weeks after surgery. The Cleveland Clinic Incontinence Score was normal in all patients except one which resolved by 6 weeks after surgery.The mean postoperative follow-up was 28 weeks without any recurrences. CONCLUSION: Transanal minimally invasive surgery is a safe and effective procedure for treatment of rectal tumors and can be performed without impairing anorectal functions.

Abstract
Endoscopic submucosal dissection (ESD) and local excision (LE) are minimally invasive procedures that can be used to treat early rectal cancer. There are no current guidelines or consensus on the optimal treatment strategy for these lesions. A systematic review was conducted to compare the efficacy and safety of ESD and LE. A meta-analysis was conducted following all aspects of the Cochrane Handbook for systematic reviews and preferred reporting items for systematic reviews and meta-analysis (PRISMA) statement. To perform the statistical analysis, the odds ratio (OR) was used for categorical variables and the weighted mean difference (WMD) for continuous variables. Four studies, involving a total of 307 patients, were identified. The length of hospital stay was longer in the group of patients undergoing LE [weighted mean difference (WMD) -1.94; 95% CI -2.85 to -1.02; p < 0.0001]. The combined results of the individual studies showed no significant differences as regards en-bloc resection rate (OR 0.82; 95% CI 0.25-2.70; p = 0.74), R0 resection rate (OR 1.53; 95% CI 0.62-3.73; p = 0.35), overall complication rate (OR 0.67; 95% CI 0.26-1.69; p = 0.40), and tumor size (WMD 0.57; 95% CI -3.64 to 4.78; p = 0.79) between ESD and LE. When adopting the fixed effect model which takes into account the study size, ESD was associated with a lower recurrence rate than LE (OR 0.15; 95% CI 0.03-0.87; p = 0.03), while with the random-effect model the difference was not significant (OR 0.18; 95% CI 0.02-2.04; p = 0.17). Over the last decade improvements in technology have improved the technical feasibility of rectal ESD. In specialized centers with highly experienced endoscopists, ESD can provide high-quality en-bloc excision of rectal neoplasms equivalent to traditional local excision.

Abstract
Background Transanal endoscopic microsurgery (TEM) for the treatment of early-stage rectal cancer has attracted attention due to its advantages of reduced surgical trauma, fewer complications, low operative mortality, rapid postoperative recovery and short hospital stay. However, there are still significant controversies regarding TEM for the treatment of rectal cancer, mainly related to the prognosis associated with this method. Objective This study sought to compare the efficacy of transanal endoscopic microsurgery (TEM) and total mesorectal excision (TME) for the treatment of T1 rectal cancer. Methods We searched the Cochrane Library, PubMed, Embase and CNKI databases. Based on the Cochrane Handbook for Systematic Reviews, we screened the trials, evaluated the quality and extracted the data. Results One randomized controlled trial (RCT) and six non-randomized controlled clinical trials (CCTs) were included in the meta-analysis (a total of 860 rectal cancer patients were included; 303 patients were treated with TEM, and 557 patients were treated with TME). Analysis revealed that all seven studies reported local recurrence rates, and there was a significant difference between the TEM and TME groups [odds ratio (OR) = 4.62, 95% confidence interval (CI) (2.03, 10.53), P = 0.0003]. A total of five studies reported distant metastasis rates, and there was no significant difference between the TEM and TME groups [OR = 0.74, 95%CI (0.32, 1.72), P = 0.49]. A total of six studies reported postoperative overall survival of the patients, and there was no significant difference between the TEM and TME groups [OR = 0.87, 95%CI(0.55, 1.38), P = 0.55]. In addition, two studies reported the postoperative disease-free survival rates of patients, and there was no significant difference between the TEM and TME groups [OR = 1.12, 95%CI (0.31, 4.12), P = 0.86]. Conclusions For patients with T1 rectal cancer, the distant metastasis, overall survival and disease-free survival rates did not differ between the TEM and TME groups, although the local recurrence rate after TEM was higher than that after TME.

Abstract
Low rectal cancer is traditionally treated by abdominoperineal resection. In recent years, several new techniques for the treatment of very low rectal cancer patients aiming to preserve the gastrointestinal continuity and to improve both the oncological as well as the functional outcomes, have been emerged. Literature suggest that when the intersphincteric resection is applied in T1-3 tumors located within 30-35 mm from the anal verge, is technically feasible, safe, with equal oncological outcomes compared to conventional surgery and acceptable quality of life. The Anterior Perineal PlanE for Ultra-low Anterior Resection technique, is not disrupting the sphincters, but carries a high complication rate, while the reports on the oncological and functional outcomes are limited. Transanal Endoscopic MicroSurgery (TEM) and TransAnal Minimally Invasive Surgery (TAMIS) should represent the treatment of choice for T1 rectal tumors, with specific criteria according to the NCCN guidelines and favorable pathologic features. Alternatively to the standard conventional surgery, neoadjuvant chemo-radiotherapy followed by TEM or TAMIS seems promising for tumors of a local stage T1sm2-3 or T2. Transanal Total Mesorectal Excision should be performed only when a board approved protocol is available by colorectal surgeons with extensive experience in minimally invasive and transanal endoscopic surgery.
