Project description:Endoscopic treatment for superficial non-ampullary duodenal tumors is technically difficult and challenging due to the anatomical characteristics of the duodenum. It is frequently complicated by procedural accidents, such as perforation. Surgical repair has long been the standard treatment for acute iatrogenic gastrointestinal perforation. However, endoscopic closure has recently emerged as an attractive alternative. In the patient presented herein, the over-the-scope-clipping system (OTSC system) was found to be useful for closing a duodenal perforation that had occurred during endoscopic submucosal dissection. For endoscopists who perform endoscopic treatment of the duodenum, endoscopic closure with the OTSC system is considered to be a technique that is necessary to master.

Project description:BACKGROUND:Surgical resection of upper gastrointestinal (GI) subepithelial tumors (SETs) is associated with significant morbidity and mortality. A new over-the-scope (OTS) clip can be used for endoscopic full-thickness resection (eFTR). We aimed to prospectively evaluate feasibility and safety of upper GI eFTR with a new, flat-based OTS clip. METHODS:Consecutive patients with a gastric or duodenal SET?<?20 mm were prospectively included. After identification of the lesion, the clip was placed and lesions were resected. Patients were followed for 1 month to assess severe adverse events (SAEs); 3-6 months after eFTR, endoscopy was performed. RESULTS:eFTR was performed on 13 lesions in 12 patients: 7 gastric and 6 duodenal SETs. Technical success was achieved in 11 cases (85%). In all 11 cases, R0-resection was achieved. In all 6 duodenal cases and in one gastric case, FTR was achieved (64%). One SAE (pain) was observed after eFTR of a gastric SET. After eFTR of duodenal SETs, several SAEs were observed: perforation (n?=?1), microperforation (n?=?3), and hemorrhage (n?=?1). During follow-up endoscopy, the clip was no longer in situ in most patients (7 of 10; 70%). CONCLUSIONS:eFTR with this new flat-based OTS clip is feasible and effective. Although gastric eFTR was safe, eFTR in the duodenum was complicated by (micro)perforation in several patients. Therefore, the design of the clip or the technique of resection needs further refinement to improve safety of resection of SET in thin-walled areas such as the duodenum before being applied in clinical practice.

Project description:ObjectivesTo evaluate the methodology, feasibility, safety, and efficacy of a novel method called over-the-scope clip- (OTSC-) associated endoscopic muscular dissection for small GSMT.MethodsA pilot study on small GSMT diameter ≤ 1 cm was performed. OTSC-associated endoscopic muscular dissection was based on the requirement of OTSC apparatus and ESD technique; after ligaturing the bottom of small GSMT by OTSC, ESD was performed to resect the tumors, and the wounds of ESD were closed by clips finally. All the patients were followed up for more than 3 months, and the complications during and after OTSC-associated endoscopic muscular dissection were recorded.ResultsA total of 7 consecutive patients with small GSMT were included. All tumors were completely dissected without any perforation or infection during and after the procedure in all cases, while three patients had mild abdominal pain, and one experienced postoperative bleeding after the procedure which was treated by the endoscopy with titanium clips. All the patients were followed by endoscopy three months later, all the wounds healed well, and all the OTSCs were still in the gastric wall.ConclusionsOTSC-associated endoscopic muscular dissection as a novel endoscopic interventional therapy should be a convenient, safe, and effective therapy for small GSMT. The short-time outcome is excellent, whereas long-term effect is unclear, and the further follow-up is needed to schedule.

Project description:BackgroundA 5-7 day hospital stay is usually needed after endoscopic submucosal dissection (ESD) of gastric tumor because of the possibility of delayed perforation or bleeding. The aim of this study was to evaluate the efficacy of combined use of a single over-the-scope clip (OTSC) and through-the-scope clips (TTSCs) to achieve complete closure of artificial gastric ulcer after ESD.MethodsWe prospectively studied 12 patients with early gastric cancer or gastric adenoma. We performed complete closure of post-ESD artificial gastric ulcer using a combination of a single OTSC and TTSCs.ResultsMean size of post-ESD artificial ulcer was 54.6 mm. The mean operating time for the closure procedure was 15.2 min., and the success rate was 91.7 % (11/12). Patients who underwent complete closure of post-ESD artificial gastric ulcer could be discharged the day after ESD and the closing procedure.ConclusionsComplete closure of post-ESD artificial gastric ulcer using a combination of a single OTSC and TTSCs is useful for shortening the period of hospitalization and reducing treatment cost.

Project description: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.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.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.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.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.

Project description:BackgroundThe 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.AimTo determine the clinical success and adverse event (AE) rates of OTSC across all GI indications.MethodsA 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.ResultsA 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).ConclusionThis 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.
