Abstract
Nowadays, endoscopic submucosal dissection (ESD) is commonly performed for the removal of large gastrointestinal lesions. Endoscopic mucosal defect closure after ESD is vital to avoid adverse events. In recent years, many innovative instruments have emerged and proved to be beneficial. In this paper, we conducted a thorough literature review and summarized the closure methods for large-size post-ESD mucosal defects over decades. We separated these methods into five categories based on the operational principle: "side closure" method, "ring closure" method, "layered closure" method, "hand suturing closure" method, and "specially designed device closure" method. Side closure with clips assisted by instruments such as threads or loops is applicable for each segment of the gastrointestinal tract to prevent postoperative bleeding. If the defect tension is too large to close with the traditional side closure methods, zigzag closure and ring closure could be applied to gather the bilateral defect edges together and achieve continuous closure. In the stomach and rectum with a high risk of submucosal dead space between the submucosa and muscular layers, side closure methods with muscle layer grasping clip or layered closure methods could enable the involvement of the deep submucosa and muscle layers. The ring closure method and specially designed devices including over-the-scope clip, Overstitch, and X-tack could resolve perforation effectively. Individual closure method requires endoscope reinsertion or sophisticated operation, which may be limited by the deep location and the narrow lumen, respectively. Although specially designed devices are expected to offer promising prospectives, the cost-effectiveness remains to be a problem.

Abstract
OBJECTIVES The purpose of this study was to evaluate the feasibility of a simple method named aspiration and coagulation (AC) for reducing the risk of postoperative bleeding after gastric endoscopic submucosal dissection (ESD). METHODS Data were retrospectively reviewed and collected from the medical records and endoscopic and pathologic reports about consecutive patients who underwent ESD for early gastric cancer or precancerous lesions or gastric submucosal lesions from January 2016 to December 2021 at the Seventh Medical Center of Chinese PLA General Hospital. Enrolled patients who underwent the AC method during ESD were included in the AC group, and the others were included in the control group. Propensity score (PS) matching (1:1 match) was used to compensate for the differences that might affect post-ESD bleeding. Massive hemorrhage and overall delayed bleeding events after gastric ESD were compared between the two groups. RESULTS Propensity score matching analysis created 242 matched pairs in the study. Characteristics of the subjects such as age and use of antithrombotic drugs were all similar between the two groups after PS matching. The rate of massive hemorrhage and overall delayed bleeding was both significantly lower in the AC group than in the control (0.4% vs. 3.3% for massive hemorrhage, P = 0.037, and 1.2% vs. 5.0% for overall delayed bleeding, P = 0.032), predominantly in mucosal lesions (0.6% vs. 4.4% for massive hemorrhage, P = 0.032, and 1.2% vs. 5.6% for overall delayed bleeding, P = 0.031). CONCLUSIONS Our study demonstrated that the AC method effectively decreased delayed bleeding events after ESD.

Abstract
OBJECTIVES The high rate of delayed bleeding after colorectal endoscopic submucosal dissection (ESD) in patients undergoing anticoagulant therapy remains a problem. Whether prophylactic clip closure reduces the rate of delayed bleeding in these patients is unclear. This study aimed to evaluate the efficacy of prophylactic clip closure in patients receiving anticoagulants. METHODS This multicenter prospective interventional trial was conducted at nine referral centers in Japan. Patients regularly taking anticoagulants, including warfarin potassium or direct oral anticoagulants, and undergoing ESD for colorectal neoplasms were enrolled. The discontinuation of anticoagulants was minimized according to recent guidelines. After the ESD, post-ESD ulcers were prophylactically closed using endoclips. The primary end-point was the incidence of delayed bleeding. The sample size was 45 lesions, and prophylactic clip closure was considered effective when the upper limit of the 90% confidence interval (CI) for delayed bleeding did not exceed 20%. RESULTS Forty-five lesions were used, and three were excluded. Complete closure was achieved in 41/42 lesions (97.6%). The overall delayed bleeding rate was low, at 4.9% (2/41; 90% [CI] 0.8-14.5), which was significantly lower than that at the prespecified threshold of 20% (P = 0.007). The median closure procedure time was 17 min, and the median number of clips was nine. No massive delayed bleeding requiring transfusion, interventional radiology, or surgery was observed, and no thromboembolic events were observed. CONCLUSION Prophylactic clip closure may reduce the risk of delayed bleeding following colorectal ESD in patients receiving anticoagulants.

Abstract
Background and study aims Complete closure of large defects after colorectal endoscopic submucosal dissection (ESD) can be problematic, especially in challenging areas or lesions larger than half the lumen circumference. We report a reopenable clip-over-the-line method for such defects and aim to investigate its feasibility through a case series. Patients and methods We retrospectively evaluated data from 30 consecutive patients who underwent ESD with defect closure using the reopenable clip-over-the-line method between October 2020 and September 2022. This method requires the first clip-with-line grasp of the oral side's defect edge and muscle layer. The next reopenable clip (with a line fed through a hole in the reopenable clip tooth) is placed on the opposing mucosal defect edge and muscle layer. This process is repeated until complete closure. The primary study outcome was the rate of complete mucosal defect closure. We also reported post-procedure bleeding or perforation. Results The median dimensions of the resected specimens were 45 mm (range, 35-70) by 39 mm (range, 29-60). Complete closure was achieved for all defects, including nine rectal defects, of which three bordered the anal verge. Of the 30 defects included in this study, nine were larger than half the lumen circumference. The median closure time was 25 minutes (range, 14-52), and the median clip number was 17 (range, 9-42). No post-procedure bleeding or perforation occurred. Conclusions The reopenable clip-over-the-line method is a feasible technique for the complete closure of large colorectal defects after endoscopic submucosal dissection, regardless of location.

Abstract
BACKGROUND Endoscopic clip closure of mucosal defects after colorectal endoscopic submucosal dissection (ESD) reduces the risk of postoperative adverse events, but achieving complete closure for large mucosal defects can be difficult. The aim of this study was to evaluate the effectiveness of the hold-and-drag closure using an SB clip compared with that of the conventional closure for mucosal defects after colorectal ESD. METHODS Eighty-four consecutive colorectal lesions resected by ESD at the Hiroshima Asa Citizens Hospital were registered and randomly allocated to two groups (Group A: SB clip, Group B: EZ clip), and then endoscopic closures were performed. We crossed-over to the SB clip in situations where the initial closure using an EZ clip was unsuccessful in achieving complete closure. Outcomes were compared and analyzed. RESULTS Forty-two lesions were randomly assigned to groups A and B. The complete closure rate was significantly higher in group A, especially in resected specimens with a diameter of 30 mm or more. Twelve lesions that failed complete closure in group B were changed to SB clips, and 95% of the whole of group B were successfully closed. There were no significant differences in procedural time, number of clips, and cost of clips between groups A and B. CONCLUSION Compared with the conventional closure, the hold-and-drag closure using an SB clip is a more suitable method for complete closure, especially for large mucosal defects of 30 mm or more. Furthermore, this is a simpler and more economical compared to a zipper closure using EZ clips.

Abstract
Colonoscopy has been shown to be an effective modality to prevent colorectal cancer (CRC) development. CRC reduction is achieved by detecting and removing adenomas, which are precursors of CRC. Most colorectal polyps are small and do not pose a significant challenge for trained and skilled endoscopists. However, up to 15% of polyps are considered “difficult”, potentially causing life-threatening complications. A difficult polyp is defined as any polyp that is challenging for the endoscopist to remove owing to its size, shape, or location. Advanced polypectomy techniques and skills are required to resect difficult colorectal polyps. There were various polypectomy techniques for difficult polyps such as endoscopic mucosal resection (EMR), underwater EMR, Tip-in EMR, endoscopic submucosal dissection (ESD), or endoscopic full-thickness resection. The selection of the appropriate modality depends on the morphology and endoscopic diagnosis. Several technologies have been developed to aid endoscopists in performing safe and effective polypectomies, especially complex procedures such as ESD. These advances include video endoscopy system, equipment assisting in advanced polypectomy, and closure devices/techniques for complication management. Endoscopists should know how to use these devices and their availability in practice to enhance polypectomy performance. This review describes several useful strategies and tips for managing difficult colorectal polyps. We also propose the stepwise approach for difficult colorectal polyps.

Abstract
Endoscopic submucosal dissection is an established method for complete resection of large and early gastrointestinal tumors. However, methods to reduce bleeding, perforation, and other adverse events after endoscopic resection (ER) have not yet been defined. Mucosal defect closure is often performed endoscopically with a clip. Recently, reopenable clips and large-teeth clips have also been developed. The over-the-scope clip enables complete defect closure by withdrawing the endoscope once and attaching the clip. Other methods involve attaching the clip-line or a ring with an anchor to appose the edges of the mucosal defect, followed by the use of an additional clip for defect closure. Since clips are limited by their grasping force and size, other methods, such as endoloop closure, endoscopic ligation with O-ring closure, and the reopenable clip over-the-line method, have been developed. In recent years, techniques often utilized for full-thickness ER of submucosal tumors have been widely used in full-thickness defect closure. Specialized devices and techniques for defect closure have also been developed, including the curved needle and line, stitches, and an endoscopic tack and suture device. These clips and suture devices are applied for defect closure in emergency endoscopy, accidental perforations, and acute and chronic fistulas. Although endoscopic defect closure with clips has a high success rate, endoscopists need to simplify and promote endoscopic closure techniques to prevent adverse events after ER.

Abstract
BACKGROUND AND AIMS Through-the-scope clips (TTSCs) are among the most common devices used to close colorectal post-endoscopic submucosal dissection (ESD) defects. Although TTSCs are easy to deliver, even to the proximal colon, simple clipping of large defects results in mucosa-mucosa closure, which could be unreliable. We developed a novel endoscopic closure technique using a modified double-layered suturing called the origami method (OGM). This method closes not only the mucosal layer but also the muscle layer with only TTSCs, which can obtain robust closure even for large defects. This study aimed to evaluate the feasibility of this new closure method for colorectal post-ESD defects. METHODS This retrospective observational study was conducted at a tertiary care hospital. We reviewed the cases of the OGM attempted after colorectal ESD at our institute between October 2021 and October 2022 and measured the clinical characteristics and outcomes of enrolled cases. RESULTS The OGM was attempted in 47 cases after colorectal ESD. Thirty-one cases (66%) were in the proximal colon, 5 (11%) in the distal colon, 6 (13%) in the upper rectum, and 5 (10%) in the lower rectum. The median defect size was 38 mm, with the largest being 85 mm. Complete closure was achieved in 44 cases (94%), including all lower rectum cases. No perforations were caused by clips during closure, and delayed perforation and bleeding were not observed. CONCLUSIONS This new closure method is feasible and recommended. The OGM could achieve reliable closure of large defects in any location, including the proximal colon and thick-walled lower rectum, using only TTSCs.

Abstract
Endoscopic submucosal dissection (ESD), which enables curative en bloc resection of early gastrointestinal neoplasms, has been an attractive minimally invasive surgery during the past two decades. Large post-ESD defects must be carefully managed to prevent adverse events (AEs). The major AEs comprise delayed bleeding (DB) and delayed perforation (DP), and overall AEs comprise DB plus DP. This review aimed to clarify the clinical efficacy and technical outcomes of endoscopic prophylactic closure for post-ESD defects. We identified studies involving ≥10 patients up to March 2022 in which endoscopic closure was applied for gastric, duodenal, and colorectal post-ESD defects. In the stomach, total rates of overall AEs and DB were significantly lower in the closure than non-closure group. In the duodenum, total rates of overall AEs, DB, and DP were significantly lower in the closure group. In the colorectum, total rates of overall AEs and DB were significantly lower in the closure group. Closure techniques, categorized into three groups (clip-based techniques, mechanical clipping, and surgical stitch-based techniques), were illustrated. Endoscopic closure demonstrated a certain ability to reduce DB after gastric, duodenal, and colorectal ESD as well as DP after duodenal ESD. Considering closure-associated costs, the indications and limitations of closure techniques should be further investigated.

Risk of Bleeding after Colorectal Endoscopic Resection in Patients with Continued Warfarin Use Compared to Heparin Replacement: A Propensity Score Matching Analysis. Gastroenterol Res Pract 2021; 2021:9415387. [PMID: 34956362 PMCID: PMC8709771 DOI: 10.1155/2021/9415387] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Revised: 10/28/2021] [Accepted: 11/19/2021] [Indexed: 12/28/2022] Open
Abstract
The Japan Gastroenterological Endoscopy Society (JGES) guidelines recommend continued warfarin treatment during gastroenterological endoscopic procedures with a high risk of bleeding as an alternative to heparin replacement in patients on warfarin therapy. However, there is insufficient evidence to support the use of warfarin in colorectal endoscopic resection (ER). The present study is aimed at verifying the risk of bleeding after ER for colorectal neoplasia (CRN) in patients with continued warfarin use. This was a single-center retrospective cohort study using clinical records. We assessed 126 consecutive patients with 159 CRNs who underwent ER (endoscopic mucosal resection, 146 cases; endoscopic submucosal dissection, 13 cases) at Hiroshima University Hospital between January 2014 and December 2019. Patients were divided into two groups: the heparin replacement group (79 patients with 79 CRNs) and the continued warfarin group (47 patients with 80 CRNs). One-to-one propensity score matching was performed to compare the bleeding rate after ER between the groups. The rate of bleeding after ER was significantly higher in the heparin replacement group than in the continued warfarin group for both before (10.1% vs. 1.3%, respectively; P = 0.0178) and after (11.9% vs. 0%, respectively; P = 0.0211) propensity score matching. None of the patients experienced thromboembolic events during the perioperative period. The risk of bleeding after colorectal ER was significantly lower in patients with continued warfarin use than in those with heparin replacement. Our data supports the recommendations of the latest JGES guidelines for patients receiving warfarin therapy.

Abstract
Endoscopic submucosal dissection (ESD) is considered superior to endoscopic mucosal resection as an endoscopic resection because of its higher en bloc resection rate, but it is more difficult to perform. As ESD techniques have become more common, and the range of treatment by ESD has expanded, the number of possible complications has also increased, and endoscopists need to manage them. In this report, we will review the management of critical complications, such as hemorrhage, perforation, and stenosis, and we will also discuss educational methods for acquiring and improving ESD skills.

Abstract
Background/Aims Endoscopic mucosal resection (EMR) is the primary treatment for duodenal adenomas; however, it is associated with a high risk of perforation and bleeding, especially with larger lesions. The goal of this study was to demonstrate the feasibility and safety of endoscopic suturing (ES) for the closure of mucosal defects after duodenal EMR.
Methods Consecutive adult patients who underwent ES of large mucosal defects after EMR of large (>2 cm) duodenal adenomas were retrospectively enrolled. The OverStitch ES system was employed for closing mucosal defects after EMR. Clinical outcomes and complications, including delayed bleeding and perforation, were documented.
Results During the study period, ES of mucosal defects was performed in seven patients in eight sessions (six for prophylaxis and two for the treatment of perforation). All ES sessions were technically successful. No early or delayed post-EMR bleeding was recorded. In addition, no clinically obvious duodenal stricture or recurrence was encountered on endoscopic follow-up evaluation, and no patients required subsequent surgical intervention.
Conclusions ES for the prevention and treatment of duodenal perforation after EMR is technically feasible, safe, and effective. ES should be considered an option for preventing or treating perforations associated with EMR of large duodenal adenomas.

Abstract
Background and study aims The need for hospital beds during the COVID-19 pandemic almost overwhelmed the health care systems all over the world. Therefore, elective non-life-saving procedures were postponed. We decided to perform all colorectal endoscopic mucosal dissections (ESDs) for challenging lesions as outpatient procedures, organizing an ad hoc path to management of any delayed post-procedural complications. The aim of the present study was to retrospectively evaluate the feasibility and safety of outpatient ESD for colorectal tumors. Patients and methods From March 2020 to May 2020, outpatient colorectal ESDs were performed for 15 challenging lesions. We retrospectively investigated feasibility and safety of the procedures, rates of en bloc resection, and complications rates. Results The mean age of the patients was 66.5 years and 40 % of the them were on antiplatelet/anticoagulation therapy. Median size of removed lesions was 45 mm (range 32-77) and 38 mm (range 24 to 55) Five patients (33 %) had rectal tumors extending to the dentate line and four (26.6 %) were recurrences on a scar of previous endoscopic or surgical local resections. All complications, such as bleeding or visible microperforation, were managed endoscopically and no delayed perforations occurred. One patient had fever (37.5 °C), while three patients complained of anal pain after ESD for a rectal tumor that extended to the dentate line (RTDL); all patients were managed conservatively. Conclusion Outpatient colorectal ESD is feasible and safe for challenging lesions. It reduces costs of hospitalization but direct access to the endoscopy service to manage potential post-ESD complications should always be guaranteed.

Abstract
OBJECTIVES Duodenal endoscopic submucosal dissection (ESD) for superficial non-ampullary duodenal epithelial tumors has a significant incidence rate of delayed perforation. Although several methods have been proposed to prevent delayed perforation, the most appropriate methods remain unclear. Currently, there is no appropriate animal model to validate methods for preventing duodenal delayed perforation. This study aimed to establish an in-vivo porcine delayed perforation model after duodenal submucosal dissection. METHODS Two porcine models underwent either ESD or surgical submucosal dissection. In the surgical dissection model, an inverted duodenal mucosa was resected with electrosurgical energy. In the ESD model, a gauze was placed behind the duodenum with grasped transverse part to improve endoscopic maneuverability. The mucosal defects after dissection were treated with omental coverage without suture in both models. All models were euthanized 0-5 days after procedure. Body weight; resection size; procedure dissection time; presence of intraoperative perforation and delayed perforation; and adhesion score were assessed. RESULTS There were no significant differences in body weight and adhesion score between the two models. Resection size was significantly larger in the surgical dissection models than in the ESD models (19 mm vs 14.3 mm, P < 0.01). Procedure time was significantly longer in the ESD models than in the surgical models (45.2 minutes vs 4.5 minutes, P < 0.01). Delayed perforation rates in the surgical dissection models and the ESD models were 0% (0/5) and 100% (5/5), respectively (P < 0.01). CONCLUSIONS This study indicated that our in-vivo porcine duodenal ESD model is beneficial to evaluate a prevention strategy for delayed perforation.

Abstract
BACKGROUND AND AIM Endoscopic submucosal dissection (ESD) has a high en bloc resection rate and is widely performed for large colorectal lesions. However, colorectal ESD is associated with a high frequency of adverse events (AEs), and the efficacy of prophylactic endoscopic closure after ESD for preventing AEs is still controversial. This meta-analysis was conducted to assess the efficacy of closure on AEs following colorectal ESD. METHODS We searched PubMed, Embase, and the Cochrane Library for eligible studies. The chi-square-based Q statistics and the I2 test were used to test for heterogeneity. Pooling was conducted using a fixed or random effects model. RESULTS We identified eight eligible studies that compared the effects of closure vs non-closure with respect to delayed bleeding, delayed perforation, and post-ESD coagulation syndrome. Compared with non-closure (5.2%), closure was associated with a lower incidence (0.9%) of delayed bleeding (pooled odd ratios [ORs]:0.19, 95% CI: 0.08-0.49) following ESD. The pooled ORs showed no significant differences in incidence of delayed perforation (pooled OR: 0.22; 95% CI: 0.05-1.03) or post-ESD coagulation syndrome (pooled OR:0.75; 95% CI: 0.26-2.18) between the closure and non-closure groups. CONCLUSION Prophylactic endoscopic closure may reduce the incidence of delayed bleeding following ESD of colorectal lesions. Future studies are needed to further illuminate risk factors and stratify high risk subjects for a cost-effective preventive strategy.

Abstract
BACKGROUND This study aimed to demonstrate the feasibility of endoscopic hand-suturing (EHS) and attainability of sustained closure after colorectal endoscopic submucosal dissection (ESD). METHODS EHS was defined as uninterrupted endoscopic suturing of the mucosal defect after colorectal ESD using an absorbable barbed suture and a through-the-scope needle holder. Following individual EHS training using an ex vivo porcine colonic model, two experienced endoscopists performed EHS. Repeat colonoscopy was performed on the third or fourth day after ESD to examine the EHS site. The primary end point was the complete EHS closure rate, and secondary end points were sustained closure and post-ESD bleeding rates. RESULTS 11 lesions were included. Median size of the mucosal defect was 38 mm (range 25 - 55 mm) and the lesion characteristics were as follows: lower rectum/upper rectum/ascending colon/cecum = 3/3/2/3, and 0-IIa/0-Is + IIa/others = 5/4/2. EHS was not attempted in two patients owing to difficulty in colonoscope reinsertion after ESD and intraoperative perforation, respectively. EHS was performed for nine lesions, and the complete EHS closure rate was 73 %. Median procedure time for suturing was 56 minutes (range 30 - 120 minutes) and median number of stitches was 8 (range 6 - 12). Sustained closure and post-ESD bleeding rates were 64 % and 9 %, respectively. CONCLUSIONS EHS achieved complete and sustained closure in the colorectum. However, EHS is not currently clinically applicable given the long procedure time. Further modifications of the technique and devices are desirable.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) enables removal of broad-based colorectal polyps or lateral spreading tumors with a higher rate of en bloc resection and a lower risk of local recurrence. However, it is technically demanding. Over the past 20 years, various equipment and innovative techniques have been developed to reduce the difficulty of ESD. The information in the literature is scattered. Our aim is to provide a comprehensive review on the setup and technical aspects of colorectal ESD. METHODS We searched the PubMed database and systemically reviewed all original and review articles related to colorectal ESD. Further manual search according to reference lists of identified articles were done. The selected articles were categorized and reviewed. Original figures were created to help readers understand some of the ESD techniques. RESULTS A total of 216 articles were identified, in which 25 of them were review articles and 191 of them were original articles. They were categorized and reviewed. An in-depth appraisal of the setting, equipment, and technical aspects of colorectal ESD was performed. CONCLUSIONS Although ESD is a technically demanding procedure that requires expert endoscopic skills, it can be mastered. With good peri-procedural preparation, sufficient knowledge of the equipment, and thorough understanding of the useful endoscopic tricks and maneuvers, colorectal ESD can be performed smoothly and safely.

Draganov PV, Wang AY, Othman MO, Fukami N. AGA Institute Clinical Practice Update: Endoscopic Submucosal Dissection in the United States. Clin Gastroenterol Hepatol 2019; 17:16-25.e1. [PMID: 30077787 DOI: 10.1016/j.cgh.2018.07.041] [Citation(s) in RCA: 264] [Impact Index Per Article: 52.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2018] [Revised: 07/21/2018] [Accepted: 07/26/2018] [Indexed: 02/07/2023]
Abstract
Endoscopic submucosal dissection (ESD) is an established endoscopic resection method in Asian countries, which is increasingly practiced in Europe and by early adopters in the United States for removal of early cancers and large lesions from the luminal gastrointestinal tract. The intent of this expert review is to provide an update regarding the clinical practice of ESD with a particular focus on its use in the United States. This review is framed around the 16 best practice advice points agreed upon by the authors, which reflect landmark and recent published articles in this field. This expert review also reflects our experience as advanced endoscopists with extensive experience in performing and teaching others to perform ESD in the United States. Best Practice Advice 1: Endoscopic submucosal dissection should be recognized as a mature endoscopic technique that enables complete removal of lesions that are too large for en bloc endoscopic mucosal resection or are at increased risk of containing cancer. Best Practice Advice 2: The safety and feasibility of endoscopic submucosal dissection for early gastric cancer is well established. The absolute indications for curative endoscopic resection include moderately and well-differentiated, nonulcerated, mucosal lesions that are ≤2 cm in size. Best Practice Advice 3: Other relative (expanded) indications for gastric endoscopic submucosal dissection include moderately and well-differentiated superficial cancers that are >2 cm, lesions ≤3 cm with ulceration or that contain early submucosal invasion, and poorly differentiated superficial cancers ≤2 cm in size. The risk of lymph node metastasis when endoscopic submucosal dissection is performed for these indications is higher than when it is performed for absolute indications but remains acceptably low. Best Practice Advice 4: Endoscopic submucosal dissection may be considered in selected patients with Barrett's esophagus with the following features: large or bulky area of nodularity, lesions with a high likelihood of superficial submucosal invasion, recurrent dysplasia, endoscopic mucosal resection specimen showing invasive carcinoma with positive margins, equivocal preprocedural histology, and intramucosal carcinoma. Best Practice Advice 5: Endoscopic submucosal dissection is the primary modality for treatment of squamous cell dysplasia and cancer confined to the superficial esophageal mucosa. Any degree of submucosal invasion caries an increased risk of lymph node metastasis and alternative/additional therapy should be considered. Best Practice Advice 6: Duodenal endoscopic submucosal dissection is associated with an increased risk of intraprocedural perforation and delayed adverse events. Duodenal endoscopic submucosal dissection should be limited to endoscopists with extensive experience in performing endoscopic submucosal dissection in other locations. It is strongly suggested that endoscopists in the United States refrain from performing duodenal endoscopic submucosal dissection during the early phase of their endoscopic submucosal dissection practice. Best Practice Advice 7: All colorectal lesions should be evaluated for suitability for endoscopic resection. Accumulating evidence has shown that the majority of colorectal neoplasms without signs of deep submucosal invasion or advanced cancer can be treated by advanced endoscopic resection techniques. Best Practice Advice 8: Colorectal neoplasms containing dysplasia confined to the mucosa have no risk for lymph node metastasis and endoscopic resection should be considered as the criterion standard. Best Practice Advice 9: Large (>2 cm) colorectal lesions frequently (>43%) require piecemeal removal when endoscopic mucosal resection is used, which is associated with increased (up to 20%) rates of recurrent neoplasia. Endoscopic submucosal dissection enables higher rates of en bloc resection and lower recurrence rates for these lesions. Patients with large complex colorectal polyps should be referred to a high-volume, specialized center for endoscopic removal by endoscopic mucosal resection or endoscopic submucosal dissection. Best Practice Advice 10: Endoscopic resection for colorectal lesions offers significant cost benefit compared with surgery, and case-based endoscopic submucosal dissection selection for high-risk lesions could offer cost savings. Best Practice Advice 11: Endoscopists in the United States embarking on performing endoscopic submucosal dissection should be familiar with currently available endoscopic tissue closure devices. Both clip closure and endoscopic suturing techniques have been shown to be effective in managing intraprocedural perforation. Complete closure of a post-endoscopic submucosal dissection site may be considered in certain circumstances based on patient factors, procedural factors, and the location of the lesion. Best Practice Advice 12: Careful coagulation of exposed blood vessels in the resection site may reduce the risk of delayed bleeding after endoscopic submucosal dissection. The use of low-voltage coagulation current is recommended for this technique. Best Practice Advice 13: Endoscopists should affix the endoscopic submucosal dissection specimen to a flat surface (eg, pin the specimen to cork board) and immerse it in formalin. An expert gastrointestinal pathologist should evaluate the specimen for margin involvement, degree of differentiation, presence or absence of lymphovascular invasion, depth of submucosal invasion (if present), and tumor budding. Best Practice Advice 14: Acquiring high-level competency in endoscopic submucosal dissection is achievable in the United States. Alternative educational models should be used in the United States because of the limited number of experts and the differing prevalence of gastrointestinal luminal diseases as compared with Asia. Best Practice Advice 15: The endoscopic submucosal dissection educational model most suited for the current environment in the United States is a stepwise approach consisting of didactic self-study, attending training courses with increasing levels of complexity, self-practice on animal models, and observation of live cases performed by experts. Endoscopists should perform their initial endoscopic submucosal dissections on patients with lesions that have well-established indications for endoscopic submucosal dissection and are of the lowest technical complexity. Best Practice Advice 16: Endoscopists in the United States who perform endoluminal resection should educate referring physicians to avoid practices that may induce submucosal fibrosis hampering future endoscopic mucosal resection or endoscopic submucosal dissection. These practices include tattooing in close proximity to or beneath a lesion for marking and partial snare resection of a portion of a lesion for histopathology.

Abstract
The diagnostic and treatment guidelines of superficial non-ampullary duodenal tumors have not been standardized due to their low prevalence. Previous reports suggested that a superficial adenocarcinoma (SAC) should be treated via local resection because of its low risk of lymph node metastasis, whereas a high-grade adenoma (HGA) should be resected because of its high risk of progression to adenocarcinoma. Therefore, pretreatment diagnosis of SAC or HGA is important to determine the appropriate treatment strategy. There are certain endoscopic features known to be associated with SAC or HGA, and current practice prioritizes the endoscopic and biopsy diagnosis of these conditions. Surgical treatment of these duodenal lesions is often related to high risk of morbidity, and therefore endoscopic resection has become increasingly common in recent years. Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are the commonly performed endoscopic resection methods. EMR is preferred due to its lower risk of adverse events; however, it has a higher risk of recurrence than ESD. Recently, a new and safer endoscopic procedure that reduces adverse events from EMR or ESD has been reported.

Abstract
Background and study aims We developed a new endoscopic closure technique using just conventional endoclips. The feasibility of endoscopic mucosa-submucosa clip closure method was evaluated in this clinical pilot study.
Patients and methods This study involved consecutive 25 patients who underwent colorectal endoscopic submucosal dissection. Endoclips were placed at the edge of the mucosal defect. Each arm of the endoclip gripped the mucosa and submucosa, respectively. The direction in which the endoclip grips were placed was parallel to the short axis of the defect. Several endoclips were applied in this way. As a result, the mucosal defect was significantly reduced in size. Additional clips were placed to achieve complete closure.
Results Mean size of resected specimen was 31.2 ± 11 mm. The success rate was 96 % (24/25). Mean procedure time was 9.6 ± 4.4 minutes. Mean number of endoclips was 9.3 ± 3.7. No complications were observed in any of the patients after the procedure.
Conclusion Endoscopic mucosa-submucosa clip closure method could close mucosal defect of size around 2 – 4 cm completely using just conventional endoclips, and it seems easy, simple and low cost.

Use of anticoagulants increases risk of bleeding after colorectal endoscopic submucosal dissection. Endosc Int Open 2018; 6:E857-E864. [PMID: 29978006 PMCID: PMC6031438 DOI: 10.1055/a-0593-5788] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2017] [Accepted: 02/20/2018] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND AND STUDY AIMS Japanese guidelines for gastroenterological endoscopy have recommended temporary withdrawal of anticoagulants (warfarin, direct oral anticoagulants [DOAC], or heparin) to prevent hemorrhagic complications during endoscopic submucosal dissection (ESD) for colorectal neoplasias (CRNs). However, serious thrombosis might occur during temporary withdrawal of anticoagulants. The current study aimed to evaluate outcomes with anticoagulants in patients undergoing ESD for CRNs. PATIENTS AND METHODS This study was a single-institution retrospective cohort study based on clinical records. We assessed 650 consecutive patients with 698 CRNs who underwent ESD at Hiroshima University Hospital between December 2010 and June 2016. The patients were divided into three groups: the warfarin group (19 patients with 19 CRNs), DOAC group (7 patients with 9 CRNs), and no-antithrombotics group (624 patients with 670 CRNs). We replaced warfarin with heparin 3 to 5 days before endoscopy. Although DOAC was suspended on the morning of endoscopy, we did not replace heparin. RESULTS Bleeding after the procedure occurred in 26.3 % (5/19), 22.0 % (2/9), and 2.7 % (18/670) of patients in the warfarin, DOAC, and no-antithrombotics groups, respectively. In the warfarin group, four patients who bled after the procedure took not only warfarin but also other antiplatelets. En bloc resection rates were 94.7 % (18/19), 100 % (9/9), and 96.6 % (647/670) in the warfarin, DOAC, and no-antithrombotics groups, respectively. No patients experienced ischemic events in the perioperative period. CONCLUSIONS Among patients undergoing ESD for CRNs, risk of bleeding was higher among patients who took anticoagulants than among those who did not. In particular, careful attention to patients who took antiplatelets in addition to warfarin before ESD for CRNs is warranted.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic submucosal dissection (ESD) has a high en bloc resection rate and is widely performed for large superficial colorectal tumors, but delayed bleeding remains one of the most common complications of colorectal ESD. The aim of the present study was to evaluate the clinical efficacy of prophylactic clip closure of mucosal defects for the prevention of delayed bleeding after colorectal ESD. PATIENTS AND METHODS We enrolled consecutive patients with colorectal lesions between January 2012 and May 2017 in this retrospective study. In the early part of this period, post-ESD mucosal defects were not closed (non-closure group); however, from January 2014, post-ESD mucosal defects were prophylactically closed with clips when possible (closure group). The main outcome measured was delayed bleeding. Variables were analyzed using the chi-squared test, Fisher's exact test, or Student's t-test. RESULTS Of 156 lesions analyzed, 61 were in the non-closure group and 95 in the closure group. Overall, delayed bleeding occurred in 5 cases (3.2 %). The delayed bleeding rate was 0 % (0/95) in the closure group and 8.2 % (5/61) in the non-closure group ( P = 0.008). The mean procedure time for closure was 10.4 ± 4.6 min (range 3 - 26 min). CONCLUSIONS We demonstrated that prophylactic clip closure of mucosal defects might reduce the risk of delayed bleeding after colorectal ESD.

Abstract
BACKGROUND AND AIMS We developed a suturing method with string and clips for a single-channel endoscope. The feasibility of the string clip suturing method is evaluated in this prospective pilot study. METHODS This study involved 10 consecutive patients who underwent endoscopic submucosal dissection (ESD) for a duodenal tumor. Polyester string was tied to the arm of a partially out thrust clip. The clip and string can be passed through the instrument channel (3.2 mm) of a single-channel endoscope. The clip with string was placed at the distal edge of the large mucosal defect. A second clip was hooked on the string and placed on the opposite side. Both clips were gathered by pulling the free end of the string, and additional clips were placed to achieve complete closure. This method was compared with that for the previous 10 patients without mucosal closure after duodenal ESD. RESULTS Mean size of resected specimens was 39.1 ± 12.4 mm. The success rate of the string clip suturing method was 100% (10/10). The mean procedure time was 23.4 ± 13.8 minutes. Perforation during ESD occurred in 1 patient and was successfully closed by this method. None of the treated patients developed serious adverse events after the procedure. Compared with the no-suture group, the length of stay was significantly shorter (P = .038). CONCLUSION The string clip suturing method appears to be a safe and effective method for closure of large mucosal defects. (Clinical trial registration number: UMIN000023698.).

Abstract
This article is a systematic review of relevant literature on endoscopic suturing as a primary closure technique for large submucosal and full-thickness defects after endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), and endoscopic full-thickness resection (EFTR). A comprehensive literature search was conducted through 2016 by using PubMed, to find peer-reviewed original articles. The specific factors considered were the procedural indications and details, success rates, clinical outcomes including complications, and study limitations. Six original articles were included in the final review: two with non-human subjects and four with human subjects. The mean success rate of endoscopic suturing was 97.4% (100% for human subjects and 95.4% for non-human subjects). The procedural time ranged from 7 to 89 min. The average size and depth of lesions were 2.71 cm (3.74 cm [human] and 1.96 cm [non-human]) and 1.52 cm, respectively. The technique itself had no reported impact on mortality. In conclusion, endoscopic suturing is a minimally invasive technique for the primary closure of defects caused by EMR, ESD, and EFTR, with a high success and low complication rate.

Abstract
Endoscopic submucosal dissection is established as a curative endoscopic method for gastrointestinal epithelial neoplasms with a high possibility of complete en bloc resection; however, postoperative adverse events of bleeding and delayed perforation remain. To prevent or minimize them, several techniques for endoscopic mucosal closure have been introduced, such as using endoscopic clips, combined use of hemoclips and supplement devices, and specially designed endoscopic suturing devices. Furthermore, endoscopic full-thickness suturing technique for gastrointestinal wall defect has been developed based on the concept in natural orifice transluminal endoscopic surgery and endoscopic full-thickness resection. Several closure techniques, including over-the-scope clip, threaded bars inserted in a hollow needle, stitches or staplers, and a curved needle and thread are reported. Secure closure of the iatrogenic defect may further expand the range of therapeutic endoscopy. Accumulation of evidence for the efficacy of endoscopic closure and establishment of these techniques are desired.

Abstract
BACKGROUND AND OBJECTIVE Endoscopic mucosa-sparing lateral dissection (EMSLD) was developed by our group, and is used to remove gastric submucosal tumor (SMT). This study aims to evaluate the feasibility and safety of this method. METHODS This retrospective study included 25 patients who underwent EMSLDs at an endoscopy center as a national key unit in china from October 2015 to July 2016. The main data collected were the size of the gastric SMT, its location and origin, en bloc resection rate, operating time, intraoperative and postoperative complications, hospitalization expense, hospital days, and follow-up after hospital discharge. RESULTS The mean (SD) size of the gastric SMTs was 18.3 (5.9) mm; 96% (24/25) of the tumors originated in the muscularis propria; and 64% (16/25) and 28% (7/25) were located in the gastric fundus and gastric body, respectively. The rate of en bloc resection was 96% (24/25), and the rate of intraoperative perforations due to endoscopic full-thickness resection was 48% (12/25). All wounds and perforations were effectively closed using endoscopic clips combined with the retained mucosa. The mean operative time was 74.2 (38.0) min. Delayed bleeding and perforation were not observed. CONCLUSION Endoscopic mucosa-sparing lateral dissection is safe and feasible for the removal of gastric SMTs. The wound can be effectively closed using the retained mucosa and endoscopic clips, even if perforation has occurred. EMSLD provides an alternative to the resection of gastric SMTs, especially for tumors with a risk of intraoperative perforation.

Abstract
Endoscopic submucosal dissection (ESD) is widely practiced in Japan and the Eastern World and is rapidly expanding in western countries for the management of early malignancies of the upper and lower gastrointestinal tube. In addition, novel therapeutic applications deriving from ESD have emerged including the treatment of achalasia, of submucosal tumors, of diverticula, of strictures and of reflux disease. An ESD procedure necessitates not only skills and specific training, but also familiarization with a vast spectrum of devices (endoscopes, high-frequency generators and their settings, endoknives, hoods, irrigation devices) and techniques (such as countertraction, artificial ulcer closure), that render the procedure faster, more efficient and safer. This technological article gives an overview on current and novel equipment for an ESD and associated techniques.

Abstract
BACKGROUND AND AIMS We developed a suturing method with a slip-knot string and clips for a single-channel endoscope. The feasibility of the slip-knot clip suturing method was evaluated in this clinical pilot study. METHODS Ten patients underwent endoscopic submucosal dissection for colorectal and duodenal tumors 5 cm or less. A slip-knot loop can be tightened when tension is applied to the free end of the string. A clip and string can be passed through an instrument channel (3.2 mm) of a single-channel endoscope. The slip-knot loop is anchored onto the mucosal defect's proximal margin with the clip. Additional clips anchoring the slip-knot loop are placed at the opposite side of the margin. The slip-knot loop is tightened by pulling the string. Additional clips are placed to achieve complete closure. RESULTS The mean size of resected specimen was 34.4 ± 10.0 mm. The success rate of the slip-knot clip suturing method was 90% (9/10). In the first patient, the string was cut because of friction, and the patient dropped out of the study. After the failure of the first patient, we used wet string to reduce friction, and slip-knot string worked effectively. The mean procedure time was 18.2 ± 3.3 minutes. CONCLUSION The slip-knot clip suturing method could close large mucosal defects completely using a single-channel endoscope. (Clinical trial registration number: UMIN000017583.).

Abstract
Background and study aims: Recently, the shielding method with polyglycolic acid (PGA) fabric and fibrin glue (P-F method) has been reported to prevent serious complications after endoscopic submucosal dissection (ESD). However, the effectiveness and mechanism to prevent complications by this method remain unclear and the corresponding basic research has not been fully conducted. Methods and results: We examined the effectiveness and mechanism of the P-F method, using a surgical ESD model of canine stomach and in vitro experiments. In the model experiment treated by P-F method or no treatment (control), ulcer perforation or penetration occurred only in the control group, but not in the P-F group. Microscopically, the P-F group showed less damages of the ulcer lesion than that of the control group, showing thicker granulation tissues including PGA fibers on the third day and excellent mucosal regeneration on the fourteenth day. In vitro culture experiments showed that fibroblasts proliferated at a significantly higher rate on PGA than on fibrin or a complex thereof. However, under hydrochloric acid treatment, fibroblasts were protected by fibrin, followed by the complex of both, and PGA. Conclusion: The P-F method exhibited a protective effect against gastric juice by fibrin glue to reduce tissue damages and a scaffold function of PGA fabric to induce better granulation formation at the earlier phase, resulting in excellent long-term tissue repair, on ulcer lesion following ESD, although the results were based on basic experiments.

"Hold-and-drag" closure technique using repositionable clips for large mucosal defects after colonic endoscopic submucosal dissection. Endosc Int Open 2016; 4:E1068-E1072. [PMID: 27747279 PMCID: PMC5063640 DOI: 10.1055/s-0042-112126] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2016] [Accepted: 07/05/2016] [Indexed: 12/16/2022] Open
Abstract
Background and study Aims: To prevent complications after colonic endoscopic submucosal dissection (ESD), we developed a new closure technique using repositionable clips. Patients and methods: The closure of post-ESD mucosal defects was attempted in 19 cases. Mucosal defects were linearly closed by holding and dragging the anal mucosal edge towards the oral mucosal edge using repositionable clips. Standard hemoclips were additionally placed to complete the closure. We retrospectively assessed the feasibility of this technique. Results: Defect closure was successfully completed in 18 cases (94.7 %). The mean defect size and the procedural time were 40.2 ± 12.0 mm (range, 24 - 71 mm) and 10.7 ± 7.2 min (range, 4.0 - 29.9 min), respectively. The mean number of repositionable clips and standard clips required for closure was 1.6 ± 0.8 (range, 1 - 3) and 7.3 ± 3.7 (range, 3 - 16), respectively. No adverse events occurred during procedures and thereafter (95 % confidence interval, 0 - 17.6 %). Conclusions: The new closure technique for large mucosal defects after colonic ESD using repositionable clips was feasible and appeared effective for preventing subsequent adverse events.

Abstract
Duodenal endoscopic resection is the most difficult type of endoscopic treatment in the gastrointestinal tract (GI) and is technically challenging because of anatomical specificities. In addition to these technical difficulties, this procedure is associated with a significantly higher rate of complication than endoscopic treatment in other parts of the GI tract. Postoperative delayed perforation and bleeding are hazardous complications, and emergency surgical intervention is sometimes required. Therefore, it is urgently necessary to establish a management protocol for preventing serious complications. For instance, the prophylactic closure of large mucosal defects after endoscopic resection may reduce the risk of hazardous complications. However, the size of mucosal defects after endoscopic submucosal dissection (ESD) is relatively large compared with the size after endoscopic mucosal resection, making it impossible to achieve complete closure using only conventional clips. The over-the-scope clip and polyglycolic acid sheets with fibrin gel make it possible to close large mucosal defects after duodenal ESD. In addition to the combination of laparoscopic surgery and endoscopic resection, endoscopic full-thickness resection holds therapeutic potential for difficult duodenal lesions and may overcome the disadvantages of endoscopic resection in the near future. This review aims to summarize the complications and closure techniques of large mucosal defects and to highlight some directions for management after duodenal endoscopic treatment.

Abstract
BACKGROUND Most mucosal defects that occur with endoscopic submucosal dissection (ESD) can be closed completely using endoscopic clips. However, benefits of such closure in wound healing are unknown. A randomized controlled study evaluated the efficacy of closure with clips compared with no closure. METHOD Twenty-eight patients who had undergone ESD were randomly divided into two groups: closure (n = 14) and non-closure groups (n = 14). In the closure group, the mucosal defect resulting from ESD was closed using endoscopic clips. Four weeks after ESD, defects in both groups were observed by colonoscopy. Efficacy was based on change in the area of the defect, percentage of complete healing in each group, and complications. RESULT Data were analyzed for 26 of the 28 patients (13, closure group; 13, non-closure group). All tumors were resected en bloc by ESD without bleeding or perforation. In the closure group, the area of the defect just after ESD was 677 ± 306 mm(2) (mean ± SD) as determined by the size of the removed lesion and had decreased to 2.17 ± 4.51 mm(2) at 4 weeks after ESD (reduction, 99.7 %), but in the non-closure group that area was 790 ± 221 mm(2) and had decreased to 27.42 ± 25.72 mm(2) at 4 weeks post-ESD (reduction, 96.2 %). The reduction rate was significantly higher in the closure than in the non-closure group (99.7 vs. 96.2 %, p = 0.010). Complete healing was 69.2 % in the closure group vs. 7.7 % in the non-closure group (p = 0.005). Multivariate analysis showed that closure of the mucosal defect (OR 24.029, 95 % CI 2.09-276.15, p = 0.011) was an independent factor associated with complete healing at 4 weeks after ESD. Delayed perforation or post-ESD bleeding was not observed in any participant. CONCLUSION Use of endoscopic clips for closure of defects after ESD is safe and efficacious in accelerating wound healing. TRIAL REGISTRATION UMIN-CTR UMIN000009112.

Abstract
BACKGROUND Clip closure of large colorectal mucosal defects may reduce the rate of adverse events in a cost-effective manner. OBJECTIVE To assess the adverse events and outcomes of clip closure of defects after endoscopic resection in patients with large colorectal tumors. DESIGN Prospective, randomized, controlled study. SETTING Single tertiary referral center. PATIENTS AND INTERVENTIONS Patients with lesions measuring 1 to 4 cm who were scheduled for endoscopic resection between March 2012 and December 2014 were randomly assigned to a clip-closure group and a no-closure group. In the clip-closure group, the defect of the resection site was completely closed with an endoclip. In the no-closure group, the defect was left open. The following primary outcome measures were assessed: delayed postoperative bleeding, postpolypectomy coagulation syndrome, perforation, and abdominal pain. Secondary outcome measures of length of hospital stay, time required for procedure, and patient's satisfaction were also assessed. RESULTS Patients and lesions had similar characteristics across both groups. For patients who underwent clip closure (n = 174), the rates of delayed postoperative bleeding (1.1% [2/174]) and postpolypectomy coagulation syndrome (0.6% [1/174]) were lower than those in the no-closure group (6.9% [12/174], P = .01 and 4.6% [8/174], P = .03). Two patients experienced perforation, 1 in each group. In the clip-closure group, 4 patients reported abdominal pain as opposed to 26 in the no-closure group (2.8% vs 16.7%, P < .01). The procedure took longer in the closure group (38.1 minutes vs 30.9 minutes, P = .04). The length of hospitalization was shorter in the closure group (3.1 days vs 4.7 days, P = .03). Total medical expense was similar between the 2 groups. Patients who underwent closure reported greater satisfaction. LIMITATION This was a single-center analysis. CONCLUSIONS Clip closure of endoscopic resection defects in patients with large colorectal tumors decreased the rate of procedure-related adverse events and did not increase the cost of hospitalization.

Abstract
The use of endoscopic submucosal dissection (ESD) for duodenal neoplasms has increased in recent years, but delayed perforation and bleeding are also known to frequently occur. We present two cases in which duodenal adenoma was successfully treated with laparoscopic-endoscopic cooperative surgery. ESD was combined with laparoscopic seromuscular sutures. The lesions in both cases were located in the second portion of the duodenum. The patients requested resection of the lesion, and we performed laparoscopic-endoscopic cooperative surgery. After the laparoscopic surgeon mobilized the duodenum, the endoscopic surgeon performed ESD for the duodenal tumor without perforation. The laparoscopic surgeon sutured the duodenal wall in the seromuscular layer to strengthen the ulcer bed after ESD. Histopathological studies confirmed that the surgical margins were tumor-free in both cases. The patients were discharged with no complications. This unique laparoscopic-endoscopic cooperative procedure is a safe and effective method for resecting superficial nonampullary duodenal tumors.

Abstract
Endoscopic therapies for lesions of the duodenum are technically more difficult than those for lesions of the other parts of the gastrointestinal tract due to the anatomical features of the duodenum, and the incidence rate of complications such as perforation and bleeding is also higher. These aforementioned trends were especially noticeable for the case of duodenal endoscopic submucosal dissection (ESD). The indication for ESD of duodenal tumors should be determined by assessment of the histopathology, macroscopic morphology, and diameter of the tumors. The three types of candidate lesions for endoscopic therapy are adenoma, carcinoma, and neuroendocrine tumors. For applying endoscopic therapies to duodenal lesions, accurate preoperative histopathological diagnosis is necessary. The most important technical issue in duodenal ESD is the submucosal dissection process. In duodenal ESD, a short needle-type knife is suitable for the mucosal incision and submucosal dissection processes, and the Small-caliber-tip Transparent hood is an important tool. After endoscopic therapies, the wound should be closed by clipping in order to prevent complications such as secondary hemorrhage and delayed perforation. At present, the criteria for selection between ESD and EMR vary among institutions. The indications for ESD should be carefully considered. Duodenal ESD should have limitations, such as the need for its being performed by experts with abundant experience in performing the procedure.

Abstract
Endoscopic submucosal dissection (ESD) is an established therapeutic technique for the treatment of gastrointestinal neoplasms. Because it is typically completed as en bloc resection, this technique provides a complete specimen for precise pathological evaluation. On the other hand, ESD is not as widely applied in treating colorectal neoplasms as with gastric cancers, due to its technical difficulty, longer procedure time, and increased risk of perforation. However, some devices that facilitate ESD and improve the safety of the procedure have been recently reported, and the use of the technique has gradually spread worldwide. Endoscopists who begin to perform ESD need to recognize the indications of ESD, the technical issue involved in this procedure, and its associated complications. This review outlines the methods and certain types of devices used for colorectal ESD.

Abstract
BACKGROUND AND AIM Colorectal endoscopic submucosal dissection (ESD) is widely carried out, but is still considered difficult. In 2010, a tumor size of ≥ 50 mm and less experience in colorectal ESD were reported as independent risk factors for complications such as perforation, delayed perforation and postoperative bleeding. In order to overcome such difficulties, we developed a scissors-type grasping device and reported the treatment results of a multicenter study. The aim of the present study was to investigate therapeutic outcomes of colorectal ESD of different tumor sizes. METHODS Group A (134 tumors): tumor size < 50 mm, and Group B (16 tumors): tumors ≥ 50 mm. All tumors were removed by ESD. We retrospectively evaluated the clinicopathological features of the tumors and the treatment results. RESULTS Age, sex, tumor location and histopathological diagnosis were not different between the two groups. Laterally spreading tumor non-granular type was more often observed in Group A (64/134, 47.8%) than in Group B (0/16, 0%). Procedure time was significantly longer in Group B (Group A: 38 min; Group B: 86 min, P < 0.01). However, procedure speed was significantly faster in Group B (Group A: 0.21 cm(2) /min; Group B: 0.37 cm(2) /min, P < 0.01). No complications were observed in either group. The en bloc resection rate, en bloc R0 resection rate, and en bloc curative resection rate were similar between the groups with no significant differences. CONCLUSIONS Procedure speed for Group B was faster than that for Group A. Group B was treated as safely as Group A.
