Abstract
Dieulafoy's lesions (DLs) are a rare cause of acute gastrointestinal bleeds (GIBs). Here we describe Over-the-Scope Clip Padlock System (OTSC-P) use to treat a gastric fundus DL with recurrent bleeding despite other interventions. The OTSC-P was created for full-thickness defect closure in the event of a perforation, but use has expanded to treatment of GIB. They consist of metal clips mounted on transparent caps, delivered via endoscope. Their size allows control of larger bleeding lesions, provides enhanced tissue stability and the firmer clip grasp reduces rebleeding or clip dislodgement.

Abstract
INTRODUCTION Over-the-scope clip (OTSC) has been used recently for primary haemostasis of peptic ulcers. This study aimed to compare the efficacy of OTSC to standard endoscopic therapy in primary treatment of patients with peptic ulcer bleeding that are of size ≥1.5 cm. The target population accounts for only 2.5% of all upper GI bleeders. METHODS This was a multicentre international randomised controlled trial from July 2017 to October 2020. All patients with Forest IIa or above peptic ulcers of ≥1.5 cm were included. Primary outcome was 30-day clinical rebleeding. Secondary endpoints include 3-day all-cause mortality, transfusion requirement, hospital stay, technical and clinical success, and further interventions. 100 patients are needed to yield a power of 80% to detect a difference of -0.15 at the 0.05 significance level (alpha) using a two-sided Z-test (pooled). RESULTS 100 patients were recruited. Success in achieving primary haemostasis was achieved in 46/50 (92%) and 48/50 (96%) in the OTSC and conventional arm, respectively. Among patients who had success in primary haemostasis, 2/46 (4.35%) patients in the OTSC arm and 9/48 (18.75%) patients in the conventional arm developed 30-day rebleeding (p=0.03). However, in an intention-to-treat analysis, there was no difference in rebleeding within 30 days (5/50 (10%) OTSC vs 9/50 (18%) standard, p=0.23) or all-cause mortality (2/50 (4%) OTSC vs 4/50 (8%) standard, p=0.68; OR=2.09, 95% CI 0.37 to 11.95). There was also no difference in transfusion requirement, hospital stay, intensive care unit admission and further interventions. CONCLUSION The routine use of OTSC as primary haemostasis in large bleeding peptic ulcers was not associated with a significant decrease in 30-day rebleeding. TRIAL REGISTRATION NUMBER NCT03160911.

Abstract
Recent advancement in endoscopic closure techniques have revolutionized the treatment of gastrointestinal perforations, leaks and fistulas. Traditionally, these have been managed surgically. The treatment strategy depends on the size and location of the defect, degree of contamination, presence of healthy surrounding tissues, patients' condition and the availability of expertise. One of the basic principles of management includes providing a barricade to the flow of luminal contents across the defect. This can be achieved with a wide range of endoscopic techniques. These include endoclips, stenting, suturing, tissue adhesives and glue, and endoscopic vacuum therapy. Each method has their distinct indications and shortcomings. Often, a combination of these techniques is required. Apart from endoscopic closure, drainage procedures by the interventional radiologist and surgical management also play an important role. In this review article, the outcomes of each of these endoscopic closure techniques in the literature is provided in tables, and practical management algorithms are being proposed.

Abstract
Weight regain following primary bariatric surgery occurs in a significant proportion of patients and is attributed to epidemiological, anatomical and metabolic factors. Surgical revision of these patients has significant risks and limited benefits. Endoscopic revisions that reduce gastric pouch size and diameter of the gastrojejunal anastomosis may offer an effective, safe, less invasive and even reproducible treatment. We herein discuss the indication, selection and feasibility of different endoscopic techniques that could be used in the management of weight regain following primary bariatric surgery. Future research could optimize a personalized approach not only in the endoscopic management but also in combination with other therapeutic modalities for weight regain after bariatric surgery.

Abstract
BACKGROUND The over-the-scope clip (OTSC) system has been increasingly utilized as a non-surgical option to endoscopically manage refractory gastrointestinal (GI) hemorrhage, perforations/luminal defects and fistulas. Limited data exist evaluating the efficacy and safety of OTSC.
AIM To determine the clinical success and adverse event (AE) rates of OTSC across all GI indications.
METHODS A PubMed search was conducted for eligible articles describing the application of the OTSC system for any indication in the GI tract. Any article or case series reporting data for less than 5 total patients was excluded. The primary outcome was the rate of clinical success. Secondary outcomes included: Technical success rate, OTSC-related AE rate and requirement for surgical intervention despite-OTSC placement. Pooled rates (per-indication and overall) were calculated as the number of patients with the event of interest divided by the total number of patients.
RESULTS A total of 85 articles met our inclusion criteria (n = 3025 patients). OTSC was successfully deployed in 94.4% of patients (n = 2856/3025). The overall rate of clinical success (all indications) was 78.4% (n = 2371/3025). Per-indication clinical success rates were as follows: (1) 86.0% (1120/1303) for GI hemorrhage; (2) 85.3% (399/468) for perforation; (3) 55.8% (347/622) for fistulae; (4) 72.6% (284/391) for anastomotic leaks; (5) 92.8% (205/221) for defect closure following endoscopic resection (e.g., following endoscopic mucosal resection or endoscopic submucosal dissection); and (6) 80.0% (16/20) for stent fixation. AE’s related to the deployment of OTSC were only reported in 64 of 85 studies (n = 1942 patients), with an overall AE rate of 2.1% (n = 40/1942). Salvage surgical intervention was required in 4.7% of patients (n = 143/3025).
CONCLUSION This systematic review demonstrates that the OTSC system is a safe and effective endoscopic therapy to manage GI hemorrhage, perforations, anastomotic leaks, defects created by endoscopic resections and for stent fixation. Clinical success in fistula management appears limited. Further studies, including randomized controlled trials comparing OTSC with conventional and/or surgical therapies, are needed to determine which indication(s) are the most effective for its use.

Abstract
Upper gastrointestinal bleeding is defined as the bleeding originating from the esophagus to the ligament of Treitz and further classified into variceal and non-variceal gastrointestinal bleeding. Non-variceal upper gastrointestinal bleeding remains a common clinical problem globally. It is associated with high mortality, morbidity, and cost of the health care system. Despite the continuous improvement of therapeutic endoscopy, the 30-d readmission rate secondary to rebleeding and associated mortality is an ongoing issue. Available Food and Drug Administration approved traditional or conventional therapeutic endoscopic modalities includes epinephrine injection, argon plasma coagulation, heater probe, and placement of through the scope clip, which can be used alone or in combination to decrease the risk of rebleeding. Recently, more attention has been paid to the novel advanced endoscopic devices for primary treatment of the bleeding lesion and as a secondary measure when conventional therapies fail to achieve hemostasis. This review highlights emerging endoscopic modalities used in the management of non-variceal upper gastrointestinal related bleeding such as over-the-scope clip, Coagrasper, hemostatic sprays, radiofrequency ablation, cryotherapy, endoscopic suturing devices, and endoscopic ultrasound-guided angiotherapy. In this review article, we will also discuss the technical aspects of the common procedures, outcomes in terms of safety and efficacy, and their advantages and limitations in the setting of non-variceal upper gastrointestinal bleeding.

Abstract
Background and aims: The aim of this study was to compare and analyze the feasibility and safety of two methods of endoscopic full-thickness resection (EFTR) for the management of challenging epithelial and subepithelial neoplasms that are not amenable to resection techniques.Material and methods: This was a retrospective case series study of patients who underwent one of two methods of EFTR, resection using ESD knives and post-resection closure with OTSC (Group 1), or closure with OTSC and secondary EFTR with snare (Group 2).Results: Of 11 patients, six were in Group 1 and five in Group 2. The mean time of the EFTR procedure was 76.83 ± 34.97 min in Group 1 which is significantly longer than that of Group 2 (p = .0128). The mean time of OSTC closure and length of hospital stay of Group 1 were also longer compared to Group 2, but the difference was not significant. Complete resection (R0) and technical success rates of Group 1 and Group 2 were 83.3% and 100% (p = .338), respectively. VAS scores of Group 1 immediately after the operation and after 24 h are significantly higher than those of Group 2 (p = .047 and p = .009, respectively). In Group 1, one patient had delayed perforation which led to fever and pneumoperitoneum, and one patient developed abdominal pain. No complications associated with the endoscopic procedure were observed in Group 2.Conclusion: EFTR of pre-resection closure are potentially faster compared with the concept of applying closure after EFTR. Larger prospective controlled studies comparing these two techniques are warranted in the future.

Abstract
Since its market launch in 2007, the endoscopic OTSC clipping system has been the object of intensive clinical research. These data were systematically collected for post-market clinical follow-up (PMCF). The aim of the study was the systematic review of the efficacy and safety of the OTSC System. The PMCF database was systematically searched for clinical data on OTSC therapy of GI hemorrhage (H), acute leaks/perforations (AL) and chronic leaks/fistulae (CL). Major outcomes were successful clip application and durable hemostasis/closure of defects. Comprehensive pooled success proportions were established by meta-analytical methods. Four-hundred-fifty-seven publications were reviewed. Fifty-eight articles comprising 1868 patients fulfilled criteria to be included in the analysis. These consisted of retrospective analyses, prospective observational trials, one randomized-controlled trial (STING) and one quasi-controlled study (FLETRock). The pooled proportion analysis revealed high overall proportions of technical success: H - mean 93.0% [95%CI 90.2-95.4], AL-mean 89.7% [95%CI 85.9-92.9] and CL-mean 83.8% [95%CI 76.9-89.7]. Pooled durable clinical success proportions were: H-mean 87.5% [95%CI 80.5-93.2], AL-mean 81.4% [95%CI 77.0-85.3] and CL-mean 63.0% [95%CI 53.0-72.3]. By pooling all clinical data gained, we conclude that OTSC application in GI hemorrhage and closure of GI lesions is safe and effective in real clinical use.

Abstract
INTRODUCTION Endoscopic hemostasis in patients with non-variceal bleeding (NVGIB) with standard therapy has improved outcomes. However, persistent bleeding and re-bleeding continues to drive morbidity and mortality. Use of over-the-scope clips (OTSC) is an emerging treatment modality for managing gastrointestinal (GI) bleeding. We performed a systematic review and meta-analysis to evaluate the ability of OTSC to achieve primary hemostasis and re-bleeding rates as primary therapy and rescue endoscopic interventions in patients with NVGIB. EVIDENCE ACQUISITION We searched articles in PubMed, Ovid Medline In- Process & Other Non-Indexed Citations, Embase, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus from inception to July 2017 using keywords such as "OTSC" and "NVGIB." EVIDENCE SYNTHESIS A total of 16 studies which involved 475 patients met the inclusion criteria. 288 patients were treated with OTSC as primary therapy while 187 patients were treated with OTSC as rescue therapy. Primary hemostasis rate achieved with primary endoscopic therapy with OTSC was 0.93 (95% CI: 0.89-0.96). Similarly, primary hemostasis rate achieved with rescue endoscopic therapy with OTSC was 0.91 (95% CI: 0.84-0.95). Re-bleeding rates after primary endoscopic therapy with OTSC was 0.21 (95% CI:0.08-0.43) and 0.25 (95% CI:0.17-0.34) with rescue therapy. There was a decreased risk of re-bleeding in patients treated with OTSC as primary therapy versus rescue therapy. RR=0.52 (95% CI: 0.31-0.89). CONCLUSIONS This meta-analysis demonstrates success on the use of OTSC as primary and rescue therapy in the management of NVGIB. Further trials should clarify the ideal setting for the use of OTSC and assess the cost of these devices as compared to standard therapy.

Abstract
Tracheoesophageal fistulas (TEF) are pathologic communications between the trachea and esophagus. TEF can lead to significant respiratory distress that may result in lethal respiratory compromise, often due to recurrent and intractable infections. Through the use of endoscopy, some TEF can be successfully repaired using different approaches depending on the size, location, availability, and experience of the treating endoscopist. The aim of this manuscript is to provide an up-to-date review of the endoscopic management of TEF for gastroenterologists.

Abstract
OPINION STATEMENT PURPOSE OF REVIEW: Upper non-variceal gastrointestinal bleeding (UNVGIB) remains an important clinical challenge for endoscopists, requiring skill and expertise for correct management. In this paper, we suggest the best strategy for an effective treatment of this complex category of patients. RECENT FINDINGS Early endoscopic examination, the increasingly widespread use of endoscopic hemostasis methods, and the most powerful antisecretory agents that induce clot stabilization have radically modified the clinical scenario for treating this pathology. While hospitalization for digestive hemorrhage is decreasing, the incidence of bleeding seems to be increasing, especially in the elderly for whom a greater use of gastrolesive drugs and the presence of comorbidities are more common. A multidisciplinary approach for initial patient evaluation and hemodynamic resuscitation prior to endoscopic treatment is crucial for correct management, prevention of rebleeding, and reduction of morbidity and mortality rates and hospital stays. Appropriate operator technical expertise, together with the availability of a wide range of endoscopes and devices, is mandatory. Newer endoscopic techniques may improve patient outcomes for difficult-to-treat lesions. Today, endoscopic hemostasis can be achieved in over 95% of patients.

Abstract
Background and study aims In patients taking different regimens of antithrombotic and/or anticoagulant therapy, endoscopic management of gastrointestinal bleeding represents a major challenge due to failing endogenous hemostasis. In this retrospective study we report on success rates with the over-the-scope clip (OTSC) system in upper and lower gastrointestinal bleeding in this high-risk patient population. Patients and methods Between February 2011 and June 2014, 75 patients were treated with an OTSC for active gastrointestinal bleeding. Success rates with the first endoscopic therapy, rebleeding episodes, their management and the influence of antithrombotic or anticoagulant therapy were analyzed retrospectively. Results Application of the OTSC resulted in immediate hemostasis (primary success rate) in all 75 patients. However, in 34.7 % a rebleeding episode was noted that could be treated by further endoscopic interventions. Only 3 patients had to be sent to the operating room because of failure of endoscopic therapy. In the rebleeding group the use of antiplatelet therapies was higher (73.1 % vs. 48.9 %). Conclusions Application of the OTSC in GI bleeding results in a high rate of primary hemostasis. Rebleeding occurs in up to 35 % of patients receiving antithrombotic/anticoagulant therapy but can be managed successfully with further endoscopic treatments. Patients in the rebleeding group were more frequently treated with antiplatelet agents. Radiological or surgical therapy was reserved for a small subgroup not successfully managed by repeated endoscopic therapies. OTSC application is the treatment of choice in high-risk patients when conventional clips used as first-line treatment fail.

Abstract
AIM To evaluate rebleeding, primary failure (PF) and mortality of patients in whom over-the-scope clips (OTSCs) were used as first-line and second-line endoscopic treatment (FLET, SLET) of upper and lower gastrointestinal bleeding (UGIB, LGIB).
METHODS A retrospective analysis of a prospectively collected database identified all patients with UGIB and LGIB in a tertiary endoscopic referral center of the University of Freiburg, Germany, from 04-2012 to 05-2016 (n = 93) who underwent FLET and SLET with OTSCs. The complete Rockall risk scores were calculated from patients with UGIB. The scores were categorized as < or ≥ 7 and were compared with the original Rockall data. Differences between FLET and SLET were calculated. Univariate and multivariate analysis were performed to evaluate the factors that influenced rebleeding after OTSC placement.
RESULTS Primary hemostasis and clinical success of bleeding lesions (without rebleeding) was achieved in 88/100 (88%) and 78/100 (78%), respectively. PF was significantly lower when OTSCs were applied as FLET compared to SLET (4.9% vs 23%, P = 0.008). In multivariate analysis, patients who had OTSC placement as SLET had a significantly higher rebleeding risk compared to those who had FLET (OR 5.3; P = 0.008). Patients with Rockall risk scores ≥ 7 had a significantly higher in-hospital mortality compared to those with scores < 7 (35% vs 10%, P = 0.034). No significant differences were observed in patients with scores < or ≥ 7 in rebleeding and rebleeding-associated mortality.
CONCLUSION Our data show for the first time that FLET with OTSC might be the best predictor to successfully prevent rebleeding of gastrointestinal bleeding compared to SLET. The type of treatment determines the success of primary hemostasis or primary failure.

Abstract
Background/Aims The over-the-scope clip (OTSC) is a device used for endoscopic closure of perforations, leaks and fistulas, and for endoscopic hemostasis. To evaluate the clinical effectiveness and safety of OTSC. Methods Between October 2013 and November 2015, 12 patients underwent OTSC placement by an experienced endoscopist. OTSC was used for the closure of gastrointestinal (GI) leaks and fistula in six patients, three of which were iatrogenic (esophageal, gastric, and duodenal) and three of which were inflammatory. In six patients, OTSC was used for hemostasis of non-variceal upper GI bleeding. Endoscopic tattooing using India ink was used to assist the accurate placement of the clip. Results All subjects except one with a colonic defect experienced immediate technical success as well as long-term clinical success, during a mean follow-up of 6 weeks. Only one clip was required to close each of the GI defects and to achieve hemostasis in all patients. There were no misfirings or complications of clips. The procedure was well tolerated, and patients were hospitalized for an average of 8 days (range, 3 to 10). Antiplatelet therapy was continued in patients with GI bleeding. Conclusions In our experience, OTSC was safe and effective for the closure of GI defect and to achieve hemostasis of non-variceal GI bleeding.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is currently being widely accepted for its role in the treatment of morbid obesity. Staple-line leakage is one of the most reported complications found in 0.5-7 % of the population, in which the Over-the-Scope Clip (OTSC) (Ovesco Endoscopy, Tübingen, Germany), a novel device, is employed. We present our experience with this system in LSG leaks. METHODS A retrospective analysis of prospectively collected data from patients with LSG leakage was performed, and these patients were treated with the OTSC system. Efficiency was defined as complete oral nutrition without any evidence of additional leakage. RESULTS Overall, 26 patients underwent endoscopic OTSC treatment. The median age was 39 years (range 26-60), and 12 were male patients (46.15 %). The mean body mass index (BMI) was 42.89 kg/m(2), and 10 patients (38.46 %) came from a revisional bariatric procedure (SRVG or LAGB). Twenty-two patients (84.61 %) had upper staple-line leaks (near the GEJ), and the remaining 4 (15.38 %) had lower antral leaks. Number of endoscopy sessions ranged from 2 to 7 (median 3). There were five failures: 2 of them had an antral leak, and the remaining 3 had an upper staple-line leak. Twenty-one (80.76 %) leaks were successfully treated within 32 days' median time till complete oral nutrition was attained (range 14-70). CONCLUSIONS The success rate was high with the OTSC system, and it is concluded to be a safe and effective treatment for LSG leaks.

Abstract
OBJECTIVES The Over-The-Scope-Clip (OTSC) has had an evolving role in endoscopic closure of gastrointestinal wall defects, in hemostasis of primary or postinterventional bleeding, and approximation of postbariatric surgery defects. Rapid and effective closure of gastrocutaneous (GC) fistulae using this device has been recently described in the literature. The aim of this study was to evaluate the technical feasibility, efficacy and safety of OTSC as an effective tool in the management of persistent GC fistulae secondary to a complication of percutaneous endoscopic gastrostomy (PEG) tube placement. METHOD In this multicenter prospective observational study, we describe our experience with OTSC in the closure of persistent GC fistulas secondary to PEG tube placement. Patients with GC fistulas were sequentially enrolled with a mean age of 84 years. Primary treatment outcome was the immediate successful closure of GC fistula and resolution of leak. Secondary outcome was no recurrence of the fistula and leaks on follow up. RESULTS A total of 10 patients were enrolled over the study period. Mean age was 84.4 ± 8.75 years. The primary treatment outcome was achieved in all the patients undergoing this intervention. Secondary outcome was observed in 9/10 (90%) subjects. No procedural complications were reported. Larger fistulae (>2.5 cm) and those with significant fibrosis were more difficult to close with the OTSC system. The mean follow-up time after OTSC application was 43.7 ± 20.57 days. A limitation of this study was that there was no control group. CONCLUSIONS OTSC application is a safe and effective endoscopic approach for the closure of persistent GC fistulae secondary to a complication of PEG tube placement.

Abstract
Over the past 30 years, the field of endoscopy has witnessed several advances. With the advent of endoscopic mucosal resection, removal of large mucosal lesions have become possible. Thereafter, endoscopic submucosal resection was refined, permitting en bloc removal of large superficial neoplasms. Such techniques have facilitated the development of antireflux mucosectomy, a promising novel treatment for gastroesophageal reflux. The introduction and use of over the scope clips has allowed for endoscopic closure of defects in the gastrointestinal tract, which were traditionally treated with surgical intervention. With the development of per-oral endoscopic myotomy (POEM), the treatment of achalasia and spastic disorders of the esophagus have been revolutionized. From the submucosal tunnelling technique developed for POEM, Per oral endoscopic tumor resection of subepithelial tumors was made possible. Simultaneously, advances in biotechnology have expanded esophageal stenting capabilities with the introduction of fully covered metal and plastic stents, as well as biodegradable stents. Once deemed a primarily diagnostic tool, endoscopy has quickly transcended to a minimally invasive intervention and therapeutic tool. These techniques are reviewed with regards to their application to benign disease of the esophagus.

Abstract
Overt or occult gastrointestinal bleeding is a frequently observed condition in routine gastroenterological practice. Occult gastrointestinal bleeding is usually a purely incidental finding, based on the discovery of iron deficiency anemia in the laboratory or blood in stool (a positive Hemoccult test). However, overt bleeding accompanied by the clinical features of tarry stool, hematemesis, or hematochezia may be a life-threatening condition, calling for immediate emergency management. In contrast to traumatology, algorithms of emergency and intensive medicine are not sufficiently validated yet for acute life-threatening bleeding. The purpose of this review was to present all established and new endoscopic hemostasis techniques and to evaluate their efficacy, as well as to provide the treating endoscopist with practical advice on how he/she could incorporate these procedures into acute medical management. The recommendations are based on inspection of the study results in the recent published literature, as well as emergency medicine algorithms in traumatology.

Abstract
Background Endoscopic full-thickness resection (EFTR) is a mini-invasive technique for gastric subepithelial tumors originating from the muscularis propria, which enables a full-thickness resection of tumors and can provide a complete basis for pathological diagnosis. Gastric fistula closure after EFTR is a challenge for endoscopists. In this study, we introduced EFTR with fistula closure using the over-the-scope clip (OTSC) system for gastric subepithelial tumors originating from the muscularis propria. Objectives To evaluate the feasibility and safety of fistula closure with OTSC by a retrospective analysis on the cases of EFTR with defect closure using OTSC for gastric subepithelial tumors originating from the muscularis propria in our hospital. Methods The patients were selected who underwent EFTR for gastric subepithelial tumors originating from the muscularis propria (tumor diameter ≤2 cm) in our hospital from October 2013 to March 2014. After a full-thickness resection of tumors, the bilateral gastric mucous membranes of defect were clamped using twin graspers and then drawn into the transparent cap of OTSC, and the OTSC was released to close the defect after full suctioning. The success rate of defect closure with OTSC was observed, and the endoscopic follow-up was performed at 1 week, 1 and 6 months after operation to check OTSC closure. Results Totally 23 patients were included into the study. The full-thickness resection rate of gastric tumors in the muscularis propria was 100 % (23/23), the success rate of defect closure was 100 %, and the average time of defect closure was 4.9 min (range 2–12 min). All patients experienced no postoperative complications such as bleeding and perforation. The postoperative follow-up time was 1–6 months (mean 3 months), and no OTSC detachment was found. Conclusions OTSC can be used to perform EFTR with defect closure for gastric tumors in the muscularis propria (tumor diameter ≤2 cm). It is simple, convenient, safe and effective.

Abstract
Perforation of a gastric tube is a rare yet lethal complication after esophagectomy for esophageal cancer treatment. Currently, over-the-scope clip (OTSC) is an effective way to treat gastric tube perforation. Due to the lack of OTSCs, we invented an alternative method composed of a titanium clip and gastroscope. The aim of this study was to describe this novel endoscopic device in the treatment of gastric tube perforation. We used a titanium clip system to treat 4 male patients (range, 53 to 77 years with gastric tube perforation. After the location of the perforation was identified by gastroscope, a titanium endoscopic clip was used to close the perforation. Successful closure of the gastric tube perforation was achieved in three patients while in one patient this failed due to his refusal to undergo reoperation. No postoperative complication was found in the three patients whose perforations were closed and the patient who refused reoperation died due to the reoccurrence of his esophago-cardiac carcinoma. The endoscopic system composed of titanium clip and gastroscope proved to be an efficient and effective device in the treatment of the patients with gastric tube perforations.

Abstract
Bleeding of peptic ulcer at the posterior duodenal bulb still is a particular endoscopic challenge with increased risk of treatment failure and worse outcome. In this article, we report successful treatment of an actively bleeding peptic ulcer located at the posterior duodenal wall, using an over-the-scope-clip in the case of a 54-year-old male patient with hemorrhagic shock. Incident primary hemostasis was achieved and no adverse events occurred during a follow-up of 60 d.

Abstract
BACKGROUND Intestinal perforation or leakage increases morbidity and mortality of surgical and endoscopic interventions. We identified criteria for use of full-covered, extractable self-expanding metal stents (cSEMS) vs. 'Over the scope'-clips (OTSC) for leak closure. METHODS Patients who underwent endoscopic treatment for postoperative leakage, endoscopic perforation, or spontaneous rupture of the upper gastrointestinal tract between 2006 and 2013 were identified at four tertiary endoscopic centers. Technical success, outcome (e.g. duration of hospitalization, in-hospital mortality), and complications were assessed and analyzed with respect to etiology, size and location of leakage. RESULTS Of 106 patients (male: 75 (71%), female: 31 (29%); age (mean ± SD): 62.5 ± 1.3 years, 72 (69%) were treated by cSEMS and 34 (31%) by OTSC. For cSEMS vs. OTSC, mean treatment duration was 41.1 vs. 25 days, p<0.001, leakage size 10 (1-50) vs. 5 (1-30) mm (median (range)), and complications were observed in 68% vs. 8.8%, p<0.001, respectively. Clinical success for primary interventional treatment was observed in 29/72 (40%) vs. 24/34 (70%, p = 0.006), and clinical success at the end of follow-up was 46/72 (64%) vs. 29/34 (85%) for patients treated by cSEMS vs. OTSC; p = 0.04. CONCLUSION OTSC is preferred in small-sized lesions and in perforation caused by endoscopic interventions, cSEMS in patients with concomitant local infection or abscess. cSEMS is associated with a higher frequency of complications. Therefore, OTSC might be preferred if technically feasible. Indication criteria for cSEMS vs. OTSC vary and might impede design of randomized studies.

Abstract
BACKGROUND AND AIM Therapeutic endoscopy has recently evolved into the treatment of complex gastrointestinal (GI) postoperative leakage, especially with over-the-scope clips (OTSC). We describe our 2-year experience of 30 patients treated for digestive fistulas using the OTSC device. METHODS This was a retrospective study conducted on patients referred for GI fistulas in two French hospitals. Technical aspects, clinical outcomes and closure rates were recorded. RESULTS Thirty patients were treated for GI leaks: 19 (63%) had a gastric fistula after laparoscopic sleeve gastrectomy (LSG); the others had rectovaginal, urethrorectal, rectovesical, gastrogastric, gastrocutaneous, esophagojejunal fistulas and colorectal anastomotic leak. Average follow up was 10.4 months. Eighteen (60%) had undergone previous endoscopic or surgical treatment. Orifice size was 3-20 mm (average 7.2 mm). Successful OTSC placement was achieved in 30 out of 34 attempts. There were four intraoperative undesired events (13.3%) but these were successfully managed. Overall success rate was 71.4% and 16 patients (53%) recovered with primary efficacy. Six patients (20%) required a subsequent endoscopic treatment. Eight patients (26.7%) required surgery for failure. In nine cases, we used one or more additional endoscopic procedures concomitantly with the OTSC combining self-expandable metal stents, standard clips and glue injection. Healing rate after LSG fistula was 88.9%, which was significantly higher than the overall rate (P = 0.01). CONCLUSION OTSC placement seems to be safe and effective for the treatment of GI fistulas. Better results were seen in leaks after LSG.

Abstract
BACKGROUND The benefit of endoscopic full-thickness resection is the improved diagnostic work-up with an integral wall specimen which allows a precise determination of the tumor or its precursor and its infiltration depth into the wall. MATERIALS AND METHODS A new endoscopic full-thickness resection device (FTRD), which is a combination of a modified over-the-scope-clip (OTSC) system with an electrocautery snare, has been tested in an experimental setting. In eleven pigs, divided into three groups, endoscopic full-thickness resection was performed in the colon at one or two sites, respectively. Seven days (n = 7) or 28 days (n = 4) after the intervention, the animals were euthanized following endoscopic examination of the resection and clip application sites. Furthermore, two different clips were tested during these animal trials in order to evaluate the most effective clip design. RESULTS The average diameter of the tissue resected with the FTRD was 3.1, 3.6, and 5.4 cm in the three groups. On follow-up endoscopy 7 days after the intervention, fibrin coating and stool residues were found at all clips, causing minor inflammatory reactions. However, the colon wall under the clip was non-inflamed. After 28 days, the serosa had primarily healed in all cases. There were also stool residues at all clips; however, no acute inflammatory reactions were seen anymore, due to complete healing. Histological assessment did not show any signs of dehiscence in the region of the scar, or ischemia in the clip area. In addition, no wound infections, such as abscess formation, were observed. CONCLUSIONS This study demonstrates the safety and efficacy of the clip-and-cut technique using the new FTRD system. With the device, a local full-thickness colon resection can be easily created, and the resulting wall defect is reliably sealed by the endoluminal application of a modified OTSC clip.

Abstract
Endoscopic management of leakages and perforations of the upper gastrointestinal tract has gained great importance as it avoids the morbidity and mortality of surgical intervention. In the past years, covered self-expanding metal stents were the mainstay of endoscopic therapy. However, two new techniques are now available that enlarge the possibilities of defect closure: endoscopic vacuum therapy (EVT), and over-the-scope clip (OTSC). EVT is performed by mounting a polyurethane sponge on a gastric tube and placing it into the leakage. Continuous suction is applied via the tube resulting in effective drainage of the cavity and the induction of wound healing, comparable to the application of vacuum therapy in cutaneous wounds. The system is changed every 3-5 d. The overall success rate of EVT in the literature ranges from 84% to 100%, with a mean of 90%; only few complications have been reported. OTSCs are loaded on a transparent cap which is mounted on the tip of a standard endoscope. By bringing the edges of the perforation into the cap, by suction or by dedicated devices, such as anchor or twin grasper, the OTSC can be placed to close the perforation. For acute endoscopy associated perforations, the mean success rate is 90% (range: 70%-100%). For other types of perforations (postoperative, other chronic leaks and fistulas) success rates are somewhat lower (68%, and 59%, respectively). Only few complications have been reported. Although first reports are promising, further studies are needed to define the exact role of EVT and OTSC in treatment algorithms of upper gastrointestinal perforations.

Current innovations in endoscopic therapy for the management of colorectal cancer: from endoscopic submucosal dissection to endoscopic full-thickness resection. BIOMED RESEARCH INTERNATIONAL 2014; 2014:925058.

Abstract
Endoscopic submucosal dissection (ESD) is accepted as a minimally invasive treatment for colorectal cancer. However, due to technical difficulties and an increased rate of complications, ESD is not widely used in the colorectum. In some cases, endoscopic treatment alone is insufficient for disease control, and laparoscopic surgery is required. The combination of laparoscopic surgery and endoscopic resection represents a new frontier in cancer treatment. Recent developments in advanced polypectomy and minimally invasive surgical techniques will enable surgeons and endoscopists to challenge current practice in colorectal cancer treatment. Endoscopic full-thickness resection (EFTR) of the colon offers the potential to decrease the postoperative morbidity and mortality associated with segmental colectomy while enhancing the diagnostic yield compared to current endoscopic techniques. However, closure is necessary after EFTR and natural transluminal endoscopic surgery (NOTES). Innovative methods and new devices for EFTR and suturing are being developed and may potentially change traditional paradigms to achieve minimally invasive surgery for colorectal cancer. The present paper aims to discuss the complementary role of ESD and the future development of EFTR. We focus on the possibility of achieving EFTR using the ESD method and closing devices.

Abstract
Recently, increasingly invasive therapeutic endoscopic procedures and more complex gastrointestinal surgeries such as endoscopic mucosal resection, endoscopic submucosal dissection, and novel laparoscopic approaches have resulted in endoscopists being confronted more frequently with perforations, fistulas, and anastomotic leakages, for which nonsurgical closure is desired. In this article, we present our experiences with the use of over-the-scope clip (OTSC) for natural orifice transluminal endoscopic surgery (NOTES) closure, prevention of perforation, anastomotic leakages, and fistula closures. The OTSC is a valuable device for closing intestinal perforations and fistulas, for NOTES closure, and for the prevention of perforation after the excision of a tumor from the proper muscle layer. Furthermore, it seems to be quite safe to perform, even by endoscopists with little experience of the technique.

Abstract
AIM: To retrospectively review the results of over-the-scope clip (OTSC) use in our hospital and to examine the feasibility of using the OTSC to treat perforations after endoscopic submucosal dissection (ESD).
METHODS: We enrolled 23 patients who presented with gastrointestinal (GI) bleeding, fistulae and perforations and were treated with OTSCs (Ovesco Endoscopy GmbH, Tuebingen, Germany) between November 2011 and September 2012. Maximum lesion size was defined as lesion diameter. The number of OTSCs to be used per patient was not decided until the lesion was completely closed. We used a twin grasper (Ovesco Endoscopy GmbH, Tuebingen, Germany) as a grasping device for all the patients. A 9 mm OTSC was chosen for use in the esophagus and colon, and a 10 mm device was used for the stomach, duodenum and rectum. The overall success rate and complications were evaluated, with a particular emphasis on patients who had undergone ESD due to adenocarcinoma. In technical successful cases we included not only complete closing by using OTSCs, but also partial closing where complete closure with OTSCs is almost difficult. In overall clinical successful cases we included only complete closing by using only OTSCs perfectly. All the OTSCs were placed by 2 experienced endoscopists. The sites closed after ESD included not only the perforation site but also all defective ulcers sites.
RESULTS: A total of 23 patients [mean age 77 years (range 64-98 years)] underwent OTSC placement during the study period. The indications for OTSC placement were GI bleeding (n = 9), perforation (n = 10), fistula (n = 4) and the prevention of post-ESD duodenal artificial ulcer perforation (n = 1). One patient had a perforation caused by a glycerin enema, after which a fistula formed. Lesion closure using the OTSC alone was successful in 19 out of 23 patients, and overall success rate was 82.6%. A large lesion size (greater than 20 mm) and a delayed diagnosis (more than 1 wk) were the major contributing factors for the overall unsuccessful clinical cases. The location of the unsuccessful lesion was in the stomach. The median operation time in the successful cases was 18 min, and the average observation time was 67 d. During the observation period, none of the patients experienced any complications associated with OTSC placement. In addition, we successfully used the OTSC to close the perforation site after ESD in 6 patients. This was a single-center, retrospective study with a small sample size.
CONCLUSION: The OTSC is effective for treating GI bleeding, fistulae as well as perforations, and the OTSC technique proofed effective treatment for perforation after ESD.

Abstract
BACKGROUND The EURO-NOTES Clinical Registry (ECR) was established as a European database to allow the monitoring and safe introduction of Natural Orifice Transluminal Endoscopic Surgery (NOTES). The aim of this study was to analyze different techniques applied and relative results during the first 2 years of the ECR. METHODS The ECR was designed as a voluntary database with online access. All members of the European Society for Gastrointestinal Endoscopy and the European Association for Endoscopic Surgery were requested to participate in the registry. Demographic and therapy data as well as data on the postoperative course are recorded in the ECR in an anonymous way. RESULTS A total of 533 patients who underwent NOTES procedures were included in the study. Four different hybrid techniques for 435 cholecystectomies were described, registering postoperative complications in 2.8% of patients, addition of a single trocar in 5.3%, and conversions to laparoscopy in 0.5%. Both flexible endoscopic and rigid laparoscopic cholecystectomy techniques proved to be safe and effective with minor differences. There was a shorter operative time in the rigid laparoscopic group. Thirty-three appendectomies were reported by transgastric and transvaginal techniques, with transvaginal techniques scoring shorter operative time and hospital stay, but with a frequent need to add more trocars. Overall complications occurred in 14.7% of patients but they did not differ significantly among the different techniques. One transvaginal and 31 transanal sigmoidectomies were included for prolapse and diverticulitis, with four postoperative complications (12.5%), but none needing further treatment. Twenty peroral esophageal myotomies were included with three postoperative complications (15.0%), but none needing further treatment. CONCLUSIONS Five years since the introduction of NOTES into clinical practice, hybrid techniques have gained considerable clinical application. Several NOTES hybrid cholecystectomy and appendectomy techniques are practicable and safe alternatives to laparoscopic procedures. Also, sigmoidectomies and peroral esophageal myotomies were described, proving feasibility and safety. Nevertheless, the real benefit of NOTES for patients still needs to be assessed.

Abstract
BACKGROUND Through-the-scope clips are commonly used for endoscopic hemostasis of gastrointestinal (GI) bleeding, but their efficacy can be suboptimal in patients with complex bleeding lesions. The over-the-scope clip (OTSC) could overcome the limitations of through-the-scope clips by allowing compression of larger amounts of tissue, allowing a more efficient hemostasis. We analyzed the use of OTSC in a consecutive case series of patients with acute GI bleeding unresponsive to conventional endoscopic treatment modalities. METHODS In a retrospective analysis of prospectively collected data in tertiary referral centers, patients undergoing emergency endoscopy for severe acute nonvariceal GI bleeding were treated with the OTSC after failure of conventional techniques. All patients underwent repeat endoscopy 2-4 days after the procedure. Data analysis included primary hemostasis, complications, and 1-month follow-up clinical outcome. RESULTS During a 10-month period, 30 patients entered the study consecutively. Bleeding lesions unresponsive to conventional endoscopic treatment (saline/adrenaline injection and through-the-scope clipping) were located in the upper and lower GI tract in 23 and 7 cases, respectively. Primary hemostasis was achieved in 29 of 30 cases (97 %). One patient with bleeding from duodenal bulb ulcer required emergent selective radiological embolization. Rebleeding occurred in two patients 12 and 24 h after the procedure; they were successfully treated with conventional saline/adrenaline endoscopic injection. CONCLUSIONS OTSC is an effective and safe therapeutic option for severe acute GI bleeding when conventional endoscopic treatment modalities fail.

Abstract
BACKGROUND The over-the-scope clip (OTSC) is a novel endoscopic tool used in the non surgical treatment of gastrointestinal perforations, fistula, and anastomotic leaks. AIMS The aim of the present study was to evaluate the therapeutic efficacy of this new endoscopic device on anastomotic postsurgical leak and fistulas or GI perforation in a tertiary referral center. PATIENTS AND METHODS The study group consisted of nine patients (three female, six male, age: 22-65 years). The indications were anastomotic leak in five patients, fistula in three patients, and perforation in one patient. Atraumatic version of OTSCs with medium sized caps, twin graspers and anchor were used. All of the patients were treated with only one OTSC. None of the patients underwent additional endoscopic treatments. RESULTS The median size of the defects were 15 mm (range 5-20 mm). OTSC was favourable in five of nine patients (three with leak, and one with fistula and perforation, each). OTSC could not be deployed or partially closed the defect in the remaining four patients because of fibrosis at the edges of the defect. Excluding the case with perforation, the median time elapsed between the diagnosis and the placement of OTSC was 35 days (range: 20-80) in the successful group and 70 days (range: 38-94) in the unsuccessful group. There were no complications due to the OTSC application or the applicator cap. CONCLUSIONS OTSC is a safe and effective device for closure of perforations and leaks. However therapeutic efficacy is lower in cases with fistulas mainly due to associated fibrosis at the borders.

Abstract
BACKGROUND Various studies have demonstrated the usefulness of the over-the-scope-clip (OTSC) to treat perforations, anastomotic leaks, and fistulae. Endoscopic removal of the OTSC was previously described in a series of 3 patients by using the Nd:YAG laser. OBJECTIVE To evaluate a new endoscopic technique to remove the OTSC. DESIGN Prospective, single-arm, pilot study in an ex vivo porcine model. INTERVENTIONS Perforations were created by using a surgical scalpel and a blunt trocar. Then they were endoscopically closed with the OTSC. Next, the OTSC was removed under endoscopic control by inserting a 0.035-inch straight hydrophilic tip guidewire into the oval hole on the side of the OTSC jaw. Afterward, the OTSC clip was removed by pulling on the wire. RESULTS Fifteen perforations were closed: with the OTSC. In all of the cases, the endoscopic closure of the defects was feasible and effective. Successful visualization of the oval hole of the OTSC was possible in 12 cases (80%), and guidewire cannulation was possible in all of these 12 cases (100%). Advancement of the guidewire through the OTSC and then the lumen of the stomach was accomplished in 8 cases (53.3%). In all of the cases with successful cannulation of the orifice, removal of the OTSC was managed safely. The result was an overall success rate of 53.3% (8 of 15 cases). LIMITATIONS Ex vivo porcine model. CONCLUSIONS Guidewire removal is a new and feasible technique to remove the OTSC. Future studies should refine the technique to enhance visualization and cannulation of the oval hole of the OTSC.

Abstract
AIM Surgical closure of high or complex anal fistulae is often a difficult challenge. A special Nitinol clip, the OTSC clip (Ovesco AG), was evaluated for fistula closure in a porcine model. METHOD A total of 20 fistulae were created in 10 animals by seton insertion. Four weeks after fistula induction the setons were removed: one internal fistula opening per animal was left untreated as control whereas the other opening was closed by the OTSC clip using a specially developed transanal clip applicator. The safety and technical feasibility of the clip application were tested. Another 4 weeks later, fistulae were macroscopically assessed for closure. For histological examination, the anorectum including the fistula tract was excised en bloc. RESULTS Four weeks after clip placement, all external and internal fistula openings were macroscopically closed. The clip application site presented with an increased scarring. Microscopically, 40% of residual tracts and a more intense chronic inflammation were seen in the untreated control fistulae. After clip placement, 10% of the fistulae persisted associated with a higher density of collagen fibres indicating a better fistula scarring and healing. No unexpected side-effects or complications caused by the clip were observed. CONCLUSION Fistula closure using the OTSC clip represents a promising sphincter-preserving minimally invasive procedure. This study demonstrated the safety and feasibility of the 'anal fistula claw' for fistula closure. In spite of limitations of the porcine model the results justify clinical applications and further investigations.

Abstract
BACKGROUND Conventional endoscopic treatment options for closure of gastrointestinal fistulae are impaired by several limitations and therefore yield high rates of recurrence. Aim of the study is the evaluation of the primary-technical and secondary-clinical success rates in closure of gastrointestinal fistulae by means of the OTSC System. DESIGN/METHODS The database Medline was systematically searched for primary research on the evaluation of the OTSC System in closure of gastrointestinal fistulae. Appraisal of studies for inclusion and data extraction were performed independently by two reviewers using an a priori determined data extraction grid. RESULTS A total of 19 primary research articles were identified. The examined studies comprised case reports as well as case series and clinical single-arm studies (n = 7) with a limited number of participants. Reviewed studies revealed a high rate of procedural success (mean 84.6%; 95% confidence interval 66.6 to 93.8%) and durable clinical success (mean 69.0%; 95% confidence interval 51.8 to 82.2%). Failed attempts and incomplete closures were mainly ascribed to the challenging effort of treating highly fibrotic chronic fistulae. CONCLUSION Endoscopic closure of gastrointestinal fistulae by means of the OTSC System is a safe and effective method.

Abstract
BACKGROUND & AIMS Acute perforations of the gastrointestinal tract are rare, severe complications of endoscopy that usually require surgical repair. Endoscopic repair of perforations would reduce the need for surgeries; we evaluated the efficacy and safety of endoscopic closure of acute perforations of the gastrointestinal tract by using a new clip device. METHODS We conducted a prospective, international, multicenter study of 36 consecutive patients (15 male) with acute iatrogenic perforations (5 esophageal, 6 gastric, 12 duodenal, and 13 colonic perforation). Endoscopic repair was performed by using the Over-the-Scope-Clip according to a standardized operating procedure. Primary end point was successful closure, which was determined as endoscopic successful closure without leakage (detected by water-soluble contrast x-ray analysis), and absence of adverse events within 30 days after the procedure. RESULTS Immediate closure was endoscopically successful in 33 patients (92%). One patient developed an esophageal perforation while the cap was introduced, and in 2 patients the perforations did not close; these 3 patients were successfully treated with surgery. None of the patients had leakage of soluble contrast on the basis of contrast x-ray. One patient with a closed colonic perforation deteriorated clinically within 6 hours after the procedure. Despite surgery, the patient died within 36 hours. The remaining 32 patients had successful endoluminal closures; the overall success rate was 89% (95% confidence interval, 75%-96%). The mean endoscopic closure time was 5 minutes 44 seconds ± 4 minutes 15 seconds. CONCLUSIONS The Over-the-Scope-Clip is effective for endoluminal closure of acute iatrogenic perforations. It allows patients to avoid surgery, and 89% of patients had successful closures without adverse events.

Abstract
BACKGROUND The mainstay of therapy for gastrocutaneous (GC) fistulas has been surgical intervention. However, endoclips are currently used for management of perforations and fistulas but are limited by their ability to entrap and hold the tissue. OBJECTIVE To report the first North American experience with a commercially available over-the-scope clip (OTSC) device, a novel and new tool for the endoscopic entrapment of tissue for the closure of fistula and perforations. METHODS The present single-centre study was conducted at a tertiary referral academic gastroenterology unit and centre for advanced therapeutic endoscopy and involved patients referred for endoscopic treatment for the closure of a GC fistula. The OTSC device was mounted on the tip of the endoscope and passed into the stomach to the level of the fistula. The targeted site of the fistula was grasped with the tissue anchoring tripod and pulled into the cap with concomitant scope channel suction. Once the tissue was trapped in the cap, a 'bear claw' clip was deployed. RESULTS The patients recovered with fistula closure. No complication or recurrence was noted. Fistula sizes >1 cm, however, were difficult to close with the OTSC system. The length of stay of the bear claw clip at the fistula site is unpredictable, which may lead to incomplete closure of the fistula. CONCLUSION Closure of a GC fistula using a novel 'bear claw' clip system is feasible and safe.
