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
Transanal endoscopic surgery (TES), which is performed through a variety of transanal endoluminal multitasking surgical platforms, was developed to facilitate endoscopic en bloc excision of rectal lesions as a minimally invasive alternative to radical proctectomy. Although the oncologic safety of TES in the treatment of malignant rectal tumors has been an area of vigorous controversy over the past two decades, TES is currently accepted as an oncologically safe approach for the treatment of carefully selected early and superficial rectal cancers. TES can also serve as both a diagnostic and potentially curative treatment of partially resected unsuspected malignant polyps. In this article, indications and contraindications for transanal endoscopic excision of early rectal cancer lesions are reviewed, as well as selection criteria for the most appropriate transanal excisional approach. Preoperative preparation and surgical technique for complications of TES will be reviewed, as well as recommended surveillance and management of upstaged tumors.

Abstract
Treatment of rectal cancer patients has been subjected to change over the past thirty years. Total mesorectal excision is considered the cornerstone of rectal cancer treatment, but is also associated with significant morbidity resulting in an impaired quality of life. The addition of neoadjuvant chemoradiotherapy to surgery has shown to improve survival and local control and may lead to a partial or even complete response (CR). This raises questions regarding the necessity for subsequent radical surgery. After careful patient selection local excision and wait-and-see approaches are explored, aiming to improve quality of life without compromising oncological outcome. A multimodality diagnostic approach for optimal staging is crucial in determining the appropriate neoadjuvant treatment regimen. Adequate endoscopic restaging of rectal tumours after multimodality treatment will aid in selecting patients who are eligible for an organ preserving approach. The role and accuracy of imaging in the detection of the primary tumour, residual rectal cancer or local recurrence seems vital. Alternative neoadjuvant regimens are currently explored to increase the rate of clinical CRs, which may support organ preserving approaches. This review aims to generate insight into the advances in diagnostics and treatment modalities in all stages of rectal cancer and will highlight future studies that may support further implementation of organ preservation treatment in rectal cancer.

Abstract
INTRODUCTION McKittrick Wheelock Syndrome (MKWS) is a rare syndrome characterized by secretory diarrhea, dehydration, prerenal acute kidney injury, and severe electrolyte abnormalities caused by a large hypersecretory villous adenoma located in the rectum or rectosigmoid junction. Transabdominal (laparoscopic) procedures are the most described procedures in the treatment of MKWS. We report an alternative surgical approach, transanal minimally invasive surgery (TAMIS), to solve this syndrome. MATERIALS AND METHODS All patients who underwent transanal endoscopic microsurgery or TAMIS were included in a prospectively collected database in our center. Between 1996 and 2015, 3 patients were found to have MKWS and treated by TAMIS. Demographics, characteristics of the adenoma, surgery-related data, and outcome were analyzed. RESULTS The first patient had a villous adenoma 0-12 cm from the anal verge. After TAMIS, she complained of a stenosis that was successfully treated by dilatation. The second patient had an impressive bulky tumor in the rectum. An endoscopic mucosal resection was attempted twice, but incompletely. Pathology analysis showed villous adenoma with high-grade dysplasia and intramucosal carcinoma. One year after TAMIS, a recurrence was detected and treated by an abdominal-perineal resection. A TAMIS was performed in the third patient because of a giant villous circular adenoma, but because of high mucus and fluid production, no proper overview could be obtained. Together with opening of the peritoneum, this prompted us to convert to a laparoscopic Hartmann procedure. Besides this technical difficulty, the patient recovered uneventful. CONCLUSIONS MKWS is a rare syndrome and missed diagnosis could result in life-threatening situations. Different endoscopic and surgical treatments are described to solve this syndrome. TAMIS should be considered as a rectum-preserving surgical treatment option for such extensive adenomas.

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
Purpose To investigate whether preoperative chemoradiotherapy (PCRT) followed by local excision (LE) is feasible approach in clinical T2N0 rectal cancer patients. Materials and Methods Patients who received PCRT and LE because of clinical T2 rectal cancer within 7 cm from anal verge between January 2006 and June 2014 were retrospectively analyzed. LE was performed in case of a good clinical response after PCRT. Patients’ characteristics, treatment record, tumor recurrence, and treatment-related complications were reviewed at a median follow-up of 49 months. Results All patients received transanal excision or transanal minimally invasive surgery. Of 34 patients, 19 patients (55.9%) presented pathologic complete response (pCR). The 3-year local recurrence-free survival and disease free-survival were 100.0% and 97.1%, respectively. There was no recurrence among the patients with pCR. Except for 1 case of grade 4 enterovesical fistula, all other late complications were mild and self-limiting. Conclusion PCRT followed by an LE might be feasible as an alternative to total mesorectal excision in good responders with clinical T2N0 distal rectal cancer.

Abstract
Colorectal cancer had a low incidence several decades ago. However, it has become a predominant cancer and now accounts for approximately 10% of cancer-related mortality in western countries. The 'rise' of colorectal cancer in developed countries can be attributed to the increasingly ageing population, unfavourable modern dietary habits and an increase in risk factors, such as smoking, low physical exercise and obesity. New treatments for primary and metastatic colorectal cancer have emerged, providing additional options for patients; these treatments include laparoscopic surgery for primary disease, more-aggressive resection of metastatic disease (such as liver and pulmonary metastases), radiotherapy for rectal cancer, and neoadjuvant and palliative chemotherapies. However, these new treatment options have had limited impact on cure rates and long-term survival. For these reasons, and the recognition that colorectal cancer is long preceded by a polypoid precursor, screening programmes have gained momentum. This Primer provides an overview of the current state of the art of knowledge on the epidemiology and mechanisms of colorectal cancer, as well as on diagnosis and treatment.

Abstract
AIM To assess the surgical outcome of transanal endoscopic surgery (TES) for rectal neoplasms in technically challenging indications. METHOD All patients who underwent TES for a rectal neoplasm from 2007 to 2014 were included. Technically challenging indications included a tumour with (i) diameter ≥ 5 cm, (ii) involving ≥ 50% of the rectal circumference and (iii) located ≥ 10 cm from the anal verge. Patients were divided into three groups according to how many of these features they had, as follows: Group 1, none; Group 2, one; Group 3, two or more. RESULTS Of the 168 patients (80 benign and 88 malignant tumours) included in the study, 73 (44%) were in Group 1, 46 (27%) in Group 2 and 49 (29%) in Group 3. There was no difference between Group 1 and Group 2 with regard to peritoneal perforation (P = 0.210), severe postoperative morbidity (P = 0.804), length of hospital stay (P = 0.444), incomplete resection (P = 0.441), piecemeal resection (P = 0.740), locoregional recurrence (P = 0.307) and long-term symptomatic rectal stenosis (P = 0.076). Conversely Group 3 showed significantly impaired results compared with Group 1 with regard to peritoneal perforation (P = 0.003), piecemeal resection (P = 0.005), incomplete resection (P = 0.025), locoregional recurrence (P = 0.035) and long-term symptomatic rectal stenosis (P < 0.001), but no difference in severe postoperative morbidity (P = 0.328). CONCLUSION Transanal endoscopic surgery for rectal neoplasms appears to be safe and effective, even in patients presenting with a technically challenging tumours. Although the short- and long-term outcomes after TES are worse in patients with highly challenging tumours, nevertheless the technique should still be considered in patients at high risk of requiring a proctectomy.

Abstract
SUMMARY The morbidity associated with radical surgery for rectal cancer has launched a revolution in increasingly less-invasive methods of resection, including a recent resurgence in transanal endoscopic surgical approaches. The next evolution in transanal surgery for rectal cancer is natural orifice translumenal endoscopic surgery (NOTES). To date, 14 series of transanal NOTES total mesorectal excision (TME) for rectal cancer have been published (n = 76). Overall, the intraoperative and postoperative complication rates of 8 and 28%, respectively, compare favorably to those expected from laparoscopic and open TME. Short-term follow-up after NOTES TME has yielded no cancer recurrence in average-risk patients. High-risk patients have cancer recurrence rates similar to those after laparoscopic TME. Overall, these early data support transanal NOTES TME as a safe and viable alternative to conventional TME. Advances in instrumentation, surgical expertise and neoadjuvant treatment may expand current indications for NOTES even further.

The surgical management of rectal cancer has evolved over the past century, with total mesorectal excision (TME) emerging as standard of care. As a result of the morbidity associated with open TME, minimally invasive techniques have become popular. Natural orifice translumenal endoscopic surgery (NOTES) has been held as the next revolution in surgical techniques, offering the possibility of 'incisionless' TME. Early clinical series of transanal TME with laparoscopic assistance (n = 72) are promising, with overall intraoperative and postoperative complication rates of 8.3% and 27.8%, respectively, similar to laparoscopic TME. The mesorectal specimen was intact in all patients, and 94.4% had negative margins. There was no oncological recurrence in average-risk patients at short-term follow up, and 2-year survival rates in high-risk patients were comparable to that after laparoscopic TME. These preliminary studies demonstrate transanal NOTES TME with laparoscopic assistance to be clinically feasible and safe given careful patient selection, surgical expertise, and appropriate procedural training. We are hopeful that with optimization of transanal instruments and surgical techniques, pure transanal NOTES TME will become a viable alternative to open and laparoscopic TME in the future.

Abstract
BACKGROUND The first author performed transanal endoscopic surgery (TEM) in 302 patients in Japan for the last 20 years, 153 of which were early rectal cancer cases. The short- and long-term outcomes of the early rectal cancer cases are herein reported. MATERIAL AND METHODS The original technique of TEM developed by Gerhard Buess was performed in all cases. The hospital records were reviewed to assess the clinical outcomes. A questionnaire was sent to the patients to analyze the long-term outcomes. RESULTS One-hundred and fifty-three early cancer cases included 115 T0 and 38 T1 lesions. Full-thickness resection was performed in 36 patients, while 117 underwent submucosal dissection. Conversion to laparoscopic low anterior resection occurred in one case. Mortality was nil. Major operative complication was noted in only one patient, who developed stenosis. Seven patients underwent immediate salvage surgery. Six patients died of recurrence of rectal cancer. Disease-free survival rate at year 5 was 93.7%. CONCLUSIONS Our study, one of the largest series in the world, confirms that TEM is a preferable option in the surgical treatment of T0 and T1a rectal carcinoma. As long as early cancer cases are treated, submucosal resection seems to be sufficient. When risk of recurrence is found by pathological examination, immediate salvage operation is mandatory to improve the prognosis.

Abstract
The first multidisciplinary consensus conference on colon and rectal cancer was held in December 2012, achieving a majority of consensus for diagnostic and treatment decisions using the Delphi Method. This article will give a critical appraisal of the topics discussed during the meeting and in the consensus document by well-known leaders in surgery that were involved in this multidisciplinary consensus process. Scientific evidence, experience and opinions are collected to support multidisciplinary teams (MDT) with arguments for medical decision-making in diagnosis, staging and treatment strategies for patients with colon or rectal cancer. Surgery is the cornerstone of curative treatment for colon and rectal cancer. Standardizing treatment is an effective instrument to improve outcome of multidisciplinary cancer care for patients with colon and rectal cancer. In this article, a review of the following focuses; Perioperative care, age and colorectal surgery, obstructive colorectal cancer, stenting, surgical anatomical considerations, total mesorectal excision (TME) surgery and training, surgical considerations for locally advanced rectal cancer (LARC) and local recurrent rectal cancer (LRRC), surgery in stage IV colorectal cancer, definitions of quality of surgery, transanal endoscopic microsurgery (TEM), laparoscopic colon and rectal surgery, preoperative radiotherapy and chemoradiotherapy, and how about functional outcome after surgery?

Abstract
BACKGROUND Transanal endoscopic operation (TEO) may be the technique of choice for the treatment of rectal lesions, both benign and selected malignant lesions, with similar survival rates to conventional surgery but with lower morbidity. METHODS In this article we present a series of 70 patients operated on with this procedure (TEO) in our center. The indications were benign rectal lesions and malignant lesions at early stages (T1) 86%. The surgical procedure was performed with the the transanal endoscopic operation platform (TEO; Karl Storz, Tüttlingen, Germany) and ultrasonic scalpel (Harmonic scalpel, Ethicon Endo-surgery,…). RESULTS The indication in 43 patients was a benign lesion (adenoma), in the other 27 the diagnosis was adenocarcinoma. After the resection, 61% of the series had a malignant lesion in the pathology report: 13 patients of the 43 with a benign lesion initially had a malignant lesion in the pathology report. Postoperative morbidity was 36%, Clavien III (5,7%). 3 patients (4%) needed emergency surgery. All of the benign lesions were completely excised, but 7 malignant lesions had resection margin involvement The median follow-up time was 26,4 months (range, 1-71 months), the overall recurrence for benign tumors was 9%, 8% for malignant pT1 and 12,5% for malignant pT2. Early salvage surgery was performed on 8 patients. CONCLUSIONS TEO allows us to excise benign rectal lesions that could not be excised with a conventional approach (endoscopic or transanal resection) with a low morbidity rate. TEO can be used for malignant rectal tumors in early stages (pT1) with pathological confirmation.

Prognostic significance of EpCAM-positive disseminated tumor cells in rectal cancer patients with stage I disease. Am J Surg Pathol 2013; 36:1809-16.

Abstract
Here we evaluated the prevalence and prognostic impact of epithelial cell adhesion molecule (EpCAM)-positive disseminated tumor cells (DTCs) in stage I rectal cancer. Further we tested the association of these single tumor cells or small tumor cell groups with the extent of peritumoral lymphangiogenesis. A total of 845 regional lymph nodes (LN) of 44 patients classified as negative on conventional histopathology were retrospectively reanalyzed with immunohistochemistry (IHC) using the monoclonal antibody Ber-Ep4 directed against EpCAM for the detection of DTCs. The degree of lymphangiogenesis in the primary tumors was assessed by IHC of the primary tumor tissue using the monoclonal antibody D2-40, which reacts with the lymphatic endothelium. The IHC results were correlated with clinico-pathologic parameters and clinical follow-up data. EpCAM-positive DTCs in LNs were detected in 8 (18.2%) of the 44 patients. During a median follow-up of 59 months, 3 (37.5%) of the 8 patients with EpCAM-positive DTCs relapsed, whereas none of the DTC-negative patients developed tumor recurrence (P=0.004). Survival analysis revealed a significant effect of the prevalence of DTCs on overall survival (P=0.0009) and on recurrence-free survival (P=0.0001). Finally, the prevalence of EpCAM-positive DTCs in perirectal LNs was significantly correlated with a high density of peritumoral lymphatic vessels (P=0.015). Our results show that DTCs may occur in stage I of rectal cancer and are associated with poor prognosis. Their occurrence seems to be linked to a high density of newly formed lymphatic vessel at the primary tumor site. According to our data, patients with DTCs in their LN might benefit from adjuvant therapy.

Abstract
Colorectal cancer (CRC) largely affects older individuals; almost half of cases occur in patients >75 years old. The incidence increases with advancing age, doubling every 7 years in patients aged ≥50 years. The medical and societal burdens of CRC will probably worsen over the coming decades as the number of older individuals (>70) continues to grow. No evidence-based guidelines are available for this age group, as older patients with CRC are generally excluded from randomized clinical trials and the fit ones who are recruited are not representative of the general elderly population. When feasible, surgery is the most successful treatment option for eradicating the primary lesion, as well as any metastases. The operative risk under elective conditions is not markedly different in older than in younger patients; however, the acute setting is to be avoided as it is associated with high operative death rates. Well-selected older patients can tolerate chemotherapy, but benefits need to be balanced against potentially limited life expectancy and reduced quality of life. The use of combination chemotherapy is an area of much controversy, but this treatment should not necessarily be withheld because of the age of the patient. Careful monitoring of toxicities and early intervention is essential in older patients undergoing chemotherapy.

Abstract
Background Transanal endoscopic microsurgery as a local therapy option for rectal neoplasms is a tissue-sparing technique that protects the anal sphincter. The present retrospective analysis reports the course of observation after local excision of adenomas and T1 low-risk carcinomas using transanal endoscopic microsurgery. Methods In a retrospective analysis we examined data on 279 patients for local recurrence. A total of 144 patients had a rectal adenoma (n = 103) or a R0 resection of low-risk T1 carcinomas (n = 41). In this collective, we also examined parameters concerning perioperative management, complications, intraoperative blood loss and duration of hospital stay. Results Patients with adenoma were on average 64.9 (range 37 to 90) years old; 83.5% of the adenomas were located 3 to 11 cm from the anocutaneous line. In adenoma patients the recurrence rate was 2.9% for an observation period of 21.8 months. The postoperative course was without any complications in 98.1% of patients. Patients with T1 low-risk carcinoma were 64.6 (range 30 to 89) years old. In all cases, an R0 resection could be performed. The recurrence rate was 9.8% for an observation period of 34.4 months. In this group the postoperative course was free of complications in 97.6% of patients. Conclusions The high efficacy of transanal endoscopic microsurgery ensures minimally invasive treatment of adenomas and low-risk T1 carcinomas with low complication rates and a low rate of therapeutic failure.
