Abstract
BACKGROUND AND AIMS The application of endoscopic suturing has revolutionized defect closures. Conventional over-the-scope suturing necessitates removal of the scope, placement of the device, and reinsertion. A single channel, single sequence, through-the-scope suturing device has been developed to improve this process. This study aims to describe the efficacy, feasibility, and safety of a through-the-scope suturing device for gastrointestinal defect closure. METHODS This was a retrospective multicenter study involving 9 centers of consecutive adult patients who underwent suturing using the X-Tack Endoscopic HeliX Tacking System (Apollo Endosurgery). The primary outcomes were technical success and long-term clinical success. Secondary outcomes included adverse events, recurrence, and reintervention rates. RESULTS In all, 56 patients (mean age 53.8, 33 women) were included. Suturing indications included fistula repair (n=22), leak repair (n=7), polypectomy defect closure (n=12), peroral endoscopic myotomy (POEM) site closure (n=7), perforation repair (n=6), and ulcers (n=2). Patients were followed at a mean duration of 74 days. Overall technical and long-term clinical success rates were 92.9% and 75%, respectively. Both technical and clinical success rates were 100% for polypectomies, POEM-site closures, and ulcers. Success rates were lower for the repair of fistulas (95.5% technical, 54.5% clinical), leaks (57.1%, 28.6%), and perforations (100%, 66.7%). No immediate adverse events were noted. CONCLUSION This novel, through-the-scope endoscopic suturing system, is a safe and feasible method to repair defects that are ≤3 cm. The efficacy of this device may be better suited for superficial defects as opposed to full-thickness defects. Larger defects will need more sutures and probably a double closure technique to provide a reinforcement layer.

Endoscopic Management for Post-Surgical Complications after Resection of Esophageal Cancer. Cancers (Basel) 2022; 14:cancers14040980. [PMID: 35205730 PMCID: PMC8870330 DOI: 10.3390/cancers14040980] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 02/11/2022] [Accepted: 02/12/2022] [Indexed: 02/04/2023] Open
Abstract
Simple Summary Flexible endoscopy has an important part in the diagnosis and treatment of postoperative complications after oncologically intended esophagectomy. Endoscopy offers the possibility of effective therapy with minimal invasiveness at the same time, and the use of endoscopic therapy procedures can avoid re-operations. In this review we present the advantages of endoscopic treatment opportunities during the last 20 years regarding patients’ treatment after esophageal cancer resection. According to prevalence and clinical relevance, four relevant postoperative complications were identified and their endoscopic treatment procedures discussed. All endoscopic therapy procedures for anastomotic bleeding, anastomotic insufficiencies, anastomotic stenosis and postoperative delayed gastric emptying are presented, including innovative developments. Abstract Background: Esophageal cancer (EC) is the sixth-leading cause of cancer-related deaths in the world. Esophagectomy is the most effective treatment for patients without invasion of adjacent organs or distant metastasis. Complications and relevant problems may occur in the early post-operative course or in a delayed fashion. Here, innovative endoscopic techniques for the treatment of postsurgical problems were developed during the past 20 years. Methods: Endoscopic treatment strategies for the following postoperative complications are presented: anastomotic bleeding, anastomotic insufficiency, delayed gastric passage and anastomotic stenosis. Based on a literature review covering the last two decades, therapeutic procedures are presented and analyzed. Results: Addressing the four complications mentioned, clipping, stenting, injection therapy, dilatation, and negative pressure therapy are successfully utilized as endoscopic treatment techniques today. Conclusion: Endoscopic treatment plays a major role in both early-postoperative and long-term aftercare. During the past 20 years, essential therapeutic measures have been established. A continuous development of these techniques in the field of endoscopy can be expected.

Abstract
OBJECTIVES Endoscopic hand suturing (EHS) is expected to decrease the risk of post-endoscopic submucosal dissection (ESD) bleeding by closing mucosal defects. We investigated the efficacy of EHS after gastric ESD in patients with antithrombotic agents. METHODS In this prospective single-arm trial, patients taking antithrombotic agents for cardiovascular disease, arrhythmia, cerebrovascular disease and/or peripheral arterial disease and having <3-cm gastric neoplasms were recruited. The mucosal defects after ESD were closed by EHS in which the needle was delivered through an overtube, and the mucosal rim of the defect was continuously sutured in a linear fashion by manipulating the needle grasped with the needle holder, followed by cutting the remnant suture and retrieval of the needle. The primary endpoint was the incidence of postoperative bleeding within 4 weeks after ESD. RESULTS Twenty-two lesions in 20 patients (continuing antiplatelet agents in 11, anticoagulant agents in eight, both in one) underwent ESD followed by EHS. All defects (median size, 30 mm; range, 12-51 mm) were completely closed by EHS and remained closed on postoperative day 3. The median number of stitches was six (range, 4-8) and median suturing time was 36 (range, 24-60) min. There were no adverse events during/after EHS or postoperative bleeding. CONCLUSIONS Postoperative bleeding was not observed in patients taking antithrombotic agents without perioperative cessation. EHS appears to be useful for prevention of post-gastric ESD bleeding in high-risk patients. (Clinical registration number: UMIN000024184).

[PMID: 32655272 PMCID: PMC7327783 DOI: 10.3748/wjg.v26.i24.3495] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2020] [Revised: 05/19/2020] [Accepted: 05/29/2020] [Indexed: 02/06/2023] Open
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
Acute perforations are one of the recognised complications of both diagnostic and therapeutic gastrointestinal (GI) endoscopy. The incidence rate varies according to the type of procedure and the anatomical location within the GI tract. For decades, surgical treatment has been the standard of care, but endoscopic closure has become a more popular approach, due to feasibility and the reduction of the burden of surgery. Various devices are available now such as through-the-scope clips, over-the-scope clips, endoscopic suturing devices, stents, bands and omental patch. All have been tested in studies done on humans or animal models, with a reasonable overall technical and clinical success rate, proving efficiency and feasibility of endoscopic closure. The choice of which device to use depends on the site and the size of the perforation. It also depends on availability of thee device and the endoscopist's experience. A number of factors that could predict success of endoscopic closure or favour surgical treatment have been suggested in different studies. After successful endoscopic closure, patients are usually kept nil by mouth and receive antibiotics for a duration that varied between different studies.

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
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 AIM The over-the-scope clip (OTSC) system is a recently developed endoscopic device. In the last few years, it has been successfully used for severe bleeding or deep wall lesions, or perforations of the gastrointestinal (GI) tract. We hereby report a series of patients with post-pancreaticogastrostomy pancreatic fistula in whom OTSC were used as endoscopic treatment. METHODS From January 2012 to July 2015, we prospectively collected data on cases of postoperative pancreatic fistula. These patients underwent pancreaticoduodenectomy in a high-volume center of hepatobiliopancreatic surgery. After conservative management, OTSC closure was done by single skilled operators in anesthesiologist-assisted deep sedation. RESULTS A total of seven patients were enrolled. According to the International Study Group of Pancreatic Surgery criteria, we observed grade B postoperative pancreatic fistula in all cases. All patients were treated with 12/6 t-type OTSC. In two cases, a second clip was successfully applied to a second site adjacent to the original closure site. In all cases, subsequent fluoroscopy showed no contrastographic spreading through the wall. There were no complications related to the procedure itself, not from the endoscopy point of view, nor from the anesthesiological perspective. There were no device malfunctions. Further clinical and endoscopic evaluation was made 8 weeks later and showed no fistula or anastomotic defect recurrence. No patients required additional endoscopic or interventional procedures. CONCLUSION In consideration of clinical and technical success, OTSC placement in POPF seems to be effective, safe and technically relatively easy to carry out.

Outcome, comorbidity, hospitalization and 30-day mortality after closure of acute perforations and postoperative anastomotic leaks by the over-the-scope clip (OTSC) in an unselected cohort of patients. Surg Endosc 2016; 31:2411-2425. [PMID: 27633439 DOI: 10.1007/s00464-016-5242-x] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2016] [Accepted: 09/07/2016] [Indexed: 12/12/2022]
Abstract
BACKGROUND Acute gastrointestinal (GI) wall defects contain a high risk of morbidity and mortality and may be closed endoscopically by a full-thickness over-the-scope clip (OTSC). METHODS Unselected consecutive patients presenting with acute non-surgical perforations or postoperative anastomotic leaks or perforations underwent attempted OTSC placement as primary closure method after interdisciplinary consensus in three tertiary referral centres. Their clinical data and intervention characteristics were evaluated in an intention to treat analysis during a 24-month period to assess closure rates, 30-day mortality, hospitalization and comorbidity. RESULTS In total, 34 patients (16 females, 18 males, 69.5 years) were included with 22 non-surgical perforations and 12 postoperative anastomotic leaks or perforations. Definitive closure of the perforations and leaks was achieved in 26/34 patients (76.5 %). Successful closure of the GI wall defect resulted in a significantly shorter hospital stay (8 days, p = 0.03) and was significantly correlated with comorbidity (r = 0.56, p = 0.005). In the group with OTSC failure, hospitalization was 18 days and 6 of 8 patients (75 %) required immediate surgery. Three deaths occurred in the group with successful OTSC closure due to comorbidity, while one death in the OTSC failure group was related to a refractory perforation. Favourable indications and locations for a successful OTSC procedure were identified as PEG complications, endoscopic or postoperative leaks of stomach, colon or rectum, respectively. CONCLUSIONS In unselected patients, OTSC was effective for closure of acute GI wall defects in more than 75 % of all patients. Clinical success and short hospitalization were best achieved in patients without comorbidity, but closure of the perforation or the anastomotic leak was found to be not the only parameter relevant for patient outcome and mortality.

Abstract
BACKGROUND Iatrogenic gastrointestinal perforation is a life-threatening complication that arises very rarely in routine endoscopic procedures, with an incidence of 0.03-0.8%. It is more likely in highly complex and invasive therapeutic interventions. In certain situations, endoscopic closure of the perforation and treatment with antibiotics can obviate the need for emergency surgical repair. METHODS This review is based on pertinent articles retrieved by a selective literature search in PubMed and on a relevant position paper. RESULTS Existing clinical studies of treatment for iatrogenic gastrointestinal perforation are mainly retrospective and uncontrolled. No randomized and controlled trials have been performed to date. If the perforation is discovered soon after it arises, endoscopic treatment can be considered. Gastrointestinal perforations that are less than 30 mm in size can be closed with a clip. In the esophagus, expanding metal stents can be used as well. Clip application is successful in 80-100% of cases of gastrointestinal perforation, and the perforation remains permanently closed in 60-100% of cases. Reports on the endoscopic treatment of esophageal perforation show mixed results, with closure rates of roughly 90% and clinical success rates of roughly 80%. If endoscopic treatment is not possible, timely laparoscopic or open surgical repair is needed. CONCLUSION The endoscopic treatment of iatrogenic perforations is safe and reliable. Success depends on early detection, adequate endoscopic closure with properly mastered technique, and the early initiation of concomitant antibiotic treatment, which must be continued for a full course. Most patients who are treated in this way do not need emergency surgery.

Abstract
AIM: To investigate the efficacy and clinical outcome of patients treated with an over-the-scope-clip (OTSC) system for severe gastrointestinal hemorrhage, perforations and fistulas.
METHODS: From 02-2009 to 10-2012, 84 patients were treated with 101 OTSC clips. 41 patients (48.8%) presented with severe upper-gastrointestinal (GI) bleeding, 3 (3.6%) patients with lower-GI bleeding, 7 patients (8.3%) underwent perforation closure, 18 patients (21.4%) had prevention of secondary perforation, 12 patients (14.3%) had control of secondary bleeding after endoscopic mucosal resection or endoscopic submucosal dissection (ESD) and 3 patients (3.6%) had an intervention on a chronic fistula.
RESULTS: In 78/84 patients (92.8%), primary treatment with the OTSC was technically successful. Clinical primary success was achieved in 75/84 patients (89.28%). The overall mortality in the study patients was 11/84 (13.1%) and was seen in patients with life threatning upper GI hemorrhage. There was no mortality in any other treatment group. In detail OTSC application lead to a clinical success in 35/41 (85.36%) patients with upper GI bleeding and in 3/3 patients with lower GI bleeding. Technical success of perforation closure was 100% while clinical success was seen in 4/7 cases (57.14%) due to attendant circumstances unrelated to the OTSC. Technical and clinic success was achieved in 18/18 (100%) patients for the prevention of bleeding or perforation after endoscopic mucosal resection and ESD and in 3/3 cases of fistula closure. Two application-related complications were seen (2%).
CONCLUSION: This largest single center experience published so far confirms the value of the OTSC for GI emergencies and complications. Further clinical experience will help to identify optimal indications for its targeted and prophylactic use.

Abstract
Over-the-scope clip (OTSC) system is becoming a new reliable technique which is available for the endoscopic closure of fistulas, bleeding, perforations and so on. We describe the case of a patient with a non-healing gastrocutaneous fistula after esophagectomy for esophageal squamous cell carcinoma which was successfully closed using an OTSC system. This is the first report of the use of OTSC to treat a non-healing gastrocutaneous fistula successfully after esophagectomy. We believe our experience will give such patients an ideal way to cure the fistula without suffering too much and also explore new application of OTSC.

Abstract
A 50-year-old woman had a percutaneous endoscopic gastrostomy (PEG) tube placed after surgery for pharyngeal cancer. After 21 months, the PEG tube was removed due to improvement of per-oral ingestion. She had taken prednisolone for 31 years for systemic lupus erythematosus. The post-PEG fistula did not close spontaneously. The cause of the fistula was slow wound healing and gastrostomy site inflammation due to long-term steroid therapy. We were able to close the fistula with an over-the-scope clipping (OTSC) system. This case suggests that OTSC is useful for closing persistent post-PEG fistulas in patients receiving long-term prednisolone therapy.

Abstract
Esophagopleural fistula (EPF) is a rare condition that is usually accompanied by severe infection and life-threatening morbidity. Here, we report the successful treatment of an EPF by closing an esophageal orifice using the over-the-scope-clip (OTSC) system without postprocedural complications. A 41-year-old man had serious thoracic and abdominal trauma due to a traffic accident. Computed tomography revealed findings suggestive of esophageal rupture due to Boerhaave syndrome. An emergent explorative operation was performed for primary repair with the insertion of a vacuum-assisted closure device. A postoperative upper gastrointestinal series revealed an EPF tract connecting the left pleural space and distal esophagus. We performed an endoscopic procedure using the "traumatic-type"OTSC to seal the EPF, and the esophageal orifice was completely healed 2 weeks postoperatively. The OTSC system might represent a safe and feasible modality for the treatment of EPF.

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
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
AIM: To evaluate the outcome of over-the-scope-clip system (OTSC) for endoscopic treatment of various indications in daily clinical practice in Switzerland.
METHODS: This prospective, consecutive case series was conducted at a tertiary care hospital from September 2010 to January 2014. Indications for OTSC application were fistulae, anastomotic leakage, perforation, unroofed submucosal lesion for biopsy, refractory bleeding, and stent fixation in the gastrointestinal (GI) tract. Primary technical success was defined as the adequate deployment of the OTSC on the target lesion. Clinical success was defined as resolution of the problem; for instance, no requirement for surgery or further endoscopic intervention. In cases of recurrence, retreatment of a lesion with a second intervention was possible. Complications were classified into those related to sedation, endoscopy, or deployment of the clip.
RESULTS: A total of 28 OTSC system applications were carried out in 21 patients [median age 64 years (range 42-85), 33% females]. The main indications were fistulae (52%), mostly after percutaneous endoscopic gastrostomy tube removal, and anastomotic leakage after GI surgery (29%). Further indications were unroofed submucosal lesions after biopsy, upper gastrointestinal bleeding, or esophageal stent fixation. The OTSC treatments were applied either in the upper (48%) or lower (52%) GI tract. The mean lesion size was 8 mm (range: 2-20 mm). Primary technical success and clinical success rates were 85% and 67%, respectively. In 53% of cases, the suction method was used without accessories (e.g., twin grasper or tissue anchor). No endoscopy-related or OTSC-related complications were observed.
CONCLUSION: OTSC is a useful tool for endoscopic closure of various GI lesions, including fistulae and leakages. Future randomized prospective multicenter trials are warranted.

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
BACKGROUND The over-the-scope clip (OTSC) provides more durable and full-thickness closure as compared with standard clips. Only case reports and small case series have reported on outcomes of OTSC closure of GI defects. OBJECTIVE To describe a large, multicenter experience with OTSCs for the management of GI defects. Secondary goals were to determine success rate by type of defect and type of therapy and to determine predictors of treatment outcomes. DESIGN Multicenter, retrospective study. SETTING Multiple, international, academic centers. PATIENTS Consecutive patients who underwent attempted OTSC placement for GI defects, either as a primary or as a rescue therapy. INTERVENTIONS OTSC placement to attempt closure of GI defects. MAIN OUTCOME MEASUREMENTS Long-term success of the procedure. RESULTS A total of 188 patients (108 fistulae, 48 perforations, 32 leaks) were included. Long-term success was achieved in 60.2% of patients during a median follow-up of 146 days. Rate of successful closure of perforations (90%) and leaks (73.3%) was significantly higher than that of fistulae (42.9%) (P < .05). Long-term success was significantly higher when OTSCs were applied as primary therapy (primary 69.1% vs rescue 46.9%; P = .004). On multivariate analysis, patients who had OTSC placement for perforations and leaks had significantly higher long-term success compared with those who had fistulae (OR 51.4 and 8.36, respectively). LIMITATIONS Retrospective design and multiple operators with variable expertise with the OTSC device. CONCLUSION OTSC is safe and effective therapy for closure of GI defects. Clinical success is best achieved in patients undergoing closure of perforations or leaks when OTSC is used for primary or rescue therapy. Type of defect is the best predictor of successful long-term closure.

Abstract
Percutaneous endoscopic gastrostomy (PEG) is a common practice for long-term nutrition of patients who are unable to take oral food. We report of an 85-year old man with a history of recurrent larynx carcinoma and hemicolectomy many years ago due to unknown reason. Laryngectomy was indicated. Preoperatively a PEG was inserted endoscopically after an abdominal ultrasonography without abnormal findings. Few months after PEG insertion, the patient was evaluated for diarrhea and insufficient feeding without signs of infection or peritonism. An upper endoscopy and computed tomography scan confirmed a buried bumper syndrome with migration of the PEG tube into the colon as a rare complication. He underwent successful colonoscopic removal of the internal bumper and closure of the colonic orifice of the fistula with the over-the-scope-clip system (OTSC). OTSC is an endoscopic device for treatment of bleeding, perforation, leak and fistula in the gastrointestinal tract. To the best of our knowledge, this is the first report of the use of OTSC for colonoscopic closure of a gastrocolocutaneous fistula due to a buried bumper syndrome with transcolonic PEG tube migration.

World J Gastroenterol 2014; 20:7767-7776. [PMID: 24976714 PMCID: PMC4069305 DOI: 10.3748/wjg.v20.i24.7767] [Citation(s) in RCA: 80] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2013] [Revised: 02/23/2014] [Accepted: 03/13/2014] [Indexed: 02/06/2023] Open
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.

Abstract
BACKGROUND AND AIM The 'bear-claw' or over-the-scope-clip system (OTSC; Ovesco Endoscopy, Tübingen, Germany) is a new clipping device developed for closure of large luminal gastrointestinal (GI) defects. The aim of the present study was to evaluate the clinical outcomes of patients treated with the OTSC. METHODS The present study was an observational, open-label, retrospective, single-arm case series conducted at two hospitals with tertiary care endoscopy. It involved 20 clip applications in 16 patients (median age 65.8 years [range 51-90 years], seven women) with GI defects from fistulas and anastomotic dehiscence and peptic ulcer bleeding. RESULTS The range of indications included gastrointestinal bleeding (n=6), gastrocutaneous fistulas (n=3), esophagotracheal and/or esophagopleural fistulae (n=3), resection ofsubmucosal tumor (n=2), stent fixation (n=1), and anastomotic leak after esophagectomy (n=1). The overall success rate for the OTSC device was 75% (12 out of 16 patients). The overall per case success rate was 70% (14 of 20 applications). Mean follow up was 10 months (range 1-10). There were no complications (0%) related to endoscopy, sedation or application of the clipping device. CONCLUSIONS The OTSC system is a useful device in a variety of clinical scenarios including the management of larger GI leaks and fistulas, GI bleeding, full-thickness resection of tumors, and stent anchoring, even in very old and frail patients.

Abstract
BACKGROUND AND STUDY AIM The novel over-the-scope clip (OTSC) allows for excellent apposition of tissue, potentially permitting hemostasis to be achieved in various types of gastrointestinal lesions. This study aimed to evaluate the usefulness and safety of OTSCs for endoscopic hemostasis in patients with upper gastrointestinal bleeding in whom traditional endoscopic methods had failed. PATIENTS AND METHODS A retrospective case series of all patients who underwent placement of an OTSC for severe recurrent upper gastrointestinal bleeding over a 14-month period was studied. Outcome data for the procedure included achievement of primary hemostasis, episodes of recurrent bleeding, and complications. RESULTS Twelve consecutive patients (67 % men; mean age 59, range 29 - 86) with ongoing upper gastrointestinal bleeding despite previous endoscopic management were included. They had a mean ASA score of 3 (range 2 - 4), a mean hemoglobin of 7.2 g/dL (range 5.2 - 9.1), and shock was present in 75 % of patients. They had all received packed red blood cells (mean 5.1 units, range 2 - 12). The etiology of bleeding was: duodenal ulcer (n = 6), gastric ulcer (n = 2) Dieulafoy lesion (n = 2), anastomotic ulceration (n = 1), Mallory - Weiss tear (n = 1). Hemostasis was achieved in all patients. Rebleeding occurred in two patients 1 day and 7 days after OTSC placement. There were no complications associated with OTSC application. CONCLUSIONS OTSC use represents an effective, easily performed, and safe endoscopic therapy for various causes of severe acute gastrointestinal bleeding when conventional endoscopic techniques have failed. This therapy should be added to the armamentarium of therapeutic endoscopists.

Abstract
BACKGROUND Advances in endoscopic and surgical techniques have increased the frequency and complexity of these procedures, and thus, the incidence of associated complications. AIMS To describe the use and clinical applications of the Over the Scope Clip (OTSC) system. METHODS An English language literature search was conducted using the key words "endoscopy" and "over the scope clip" in order to identify human studies evaluating the application of OTSC from January 2001 to August 2012. The indication, efficacy, complications, and limitations were recorded. RESULTS Overall success rates of OTSC based on current literature range are in the range of 75% to 100% for closure of iatrogenic gastrointestinal perforations, 38% to 100% for closure of gastrointestinal fistulas, 50% to 100% for anastomotic leaks, and 71% to 100% for bleeding lesions. OTSCs have shown 100% success rates in managing postbariatric surgery weight gain secondary to dilation of the gastrojejunal pouch. CONCLUSION OTSC is easy to use with good results, thus decreasing the morbidity and mortality associated with the complications secondary to both diagnostic and therapeutic endoscopy and avoiding surgery in many situations.

Abstract
INTRODUCTION Anorectal fistulas represent a troublesome condition for both patient and surgeon. The OTSC® Proctology clip system is a new device for transanal anorectal fistula closure. MATERIAL AND METHODS The OTSC® Proctology system was evaluated in a prospective clinical study undertaken in two surgical proctological centers. Ten patients (three women, seven men; median age 55 years, range 25-73 years) with nine transsphincteric and one suprasphincteric fistulas were enrolled into the study. RESULTS The median operation time was 30 minutes (range 20-45 minutes). There were no intraoperative technical or surgical complications. Postoperatively, no patient reported intolerable discomfort, immoderate pain or foreign body sensation in the anal region. At follow-up examination six months after surgery, nine out of ten patients had no clinical signs or symptoms of their previous fistula and were considered as healed (success rate 90%). In one patient persistency of the fistula was noted due to spontaneous early clip detachment on the third postoperative day. DISCUSSION These first data demonstrate the efficacy of the OTSC® Proctology system in the treatment of anal fistulas. Currently, more patients were enrolled into this prospective study to allow further evaluation of this new device and to assess its future role in relation to established surgical strategies for anorectal fistulas.

Abstract
Boerhaave syndrome is a spontaneous perforation of the oesophagus secondary to forceful emesis. Surgery has been advocated in delayed presentations of Boerhaave's syndrome with mediastinitis. The over-the-scope clip (OTSC) by OVESCO® (Tubingen, Germany) has been used in the endoscopic management of gastrointestinal bleeds, fistulae and anastamotic leaks. We describe the successful endoscopic use of the OTSC in a delayed presentation of Boerhaave syndrome with mediastinitis. A 69-year-old gentleman underwent a computerised tomography scan, which demonstrated a lower oesophageal perforation and mediastinitis 7 days after admission, having presented with forceful emesis and chest discomfort. During endoscopy the defect was visualized and successfully closed using the OTSC. This resulted in a favourable outcome and is a technique not previously described in the literature to manage this condition.

Abstract
BACKGROUND Reliable closure is a prerequisite for conventional and innovative endoscopic procedures, such as NOTES. The purpose of this study is the systematic evaluation of the procedural and clinical success rates in closure of iatrogenic gastrointestinal perforations and acute anastomotic leaks by means of the over-the-scope-clip system (OTSC(®)). DESIGN PubMed and other sources were searched systematically for clinical and preclinical research on the evaluation of the OTSC System for closure of gastrointestinal perforations and leaks. Appraisal of studies for inclusion and data extraction was performed independently by two reviewers using an a priori determined data extraction grid. Major endpoints to be extracted were data on procedural success (successful clip application) and clinical access (durable closure of defect without secondary adjunct therapy). RESULTS A total of 17 clinical research articles/abstracts and 22 preclinical research articles/abstracts were identified. The examined clinical studies comprised case series and clinical single-arm studies. The reviewed studies revealed a consistently high mean rate of procedural success of 80-100 % and durable clinical success of 57-100 %. An identified major drawback preventing successful clip application was occurrence of fibrotic or inflamed lesion edges. Usage of the OTSC System was accompanied by neither major clip-related nor application-related complication. In experimental settings, closure of larger perforations and gastric access sites of NOTES or endoscopic full-thickness resection were achieved with high rates of success. CONCLUSIONS Because randomized, clinical trials are not available in this field of indication, the evaluation is based on small case series. Nevertheless, by pooling all experience gained, we conclude that endoscopic closure of iatrogenic gastrointestinal perforations and acute anastomotic leaks by means of the OTSC System is a safe and effective method.

Neben der chirurgischen Therapie sind zunehmend endoskopische Behandlungsoptionen möglich. <b><i>Methode: </i></b>Literaturübersicht. <b><i>Ergebnisse: </i></b>Therapieoptionen von Anastomoseninsuffizienzen sind abhängig von der klinischen Symptomatik, der Art der Anastomose, der Defektgröße, den lokalen Gewebeverhältnissen sowie dem Zeitpunkt der Diagnose.

Bei erhaltener Gewebeperfusion können die Leckagen lokal übernäht oder endoskopisch verschlossen werden. Die Ergebnisse für die Stenttherapie nach Ösophagus- und Magenresektionen sind für moderne Stents sehr Erfolg versprechend. Im Gegensatz dazu sind die Ergebnisse der endoskopischen Stenttherapie bei Insuffizienz nach kolorektalen Eingriffen enttäuschend; dafür steht hier mit der Schwammtherapie eine vielversprechende endoskopische Alternative zur Verfügung. <b><i>Schlussfolgerung: </i></b>Die aktuellen Daten zeigen, dass neue laparoskopische und endoskopische Optionen zur Therapie von Anastomoseninsuffizienzen bestehen, die jedoch noch in prospektiven und randomisierten Studien evaluiert werden müssen.

Abstract
Oesophagopleural fistula is a recognized complication of pneumonectomy. Surgical repair with direct closure and reinforcement with omentum, muscle or pleural flap is the mainstay of definitive treatment. However, this option might not be suitable for all patients. The authors report on the case of a 63-year old female refusing surgical repair of an oesophagopleural fistula after left pneumonectomy. A novel approach (using an Amplatzer atrial septal occluder device) for fistula closure was attempted. Despite a promising initial result, the procedure failed. This is the first report on the use of a septal occluder to try and close an oesophagopleural fistula.

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
Abstract Surgical treatment of high or complex anal fistulas often renders unsatisfying results. This is the report of the first successful closure of such anal fistula using a special Nitinol clip and applicator, the OTSC® Proctology system (Ovesco AG, Tuebingen, Germany): A 54-year old female patient was suffering from a high transsphincteric anal fistula. After seton drainage of the fistula for ten weeks, the fistula track was debrided using a special fistula brush. After transanal clip release from the applicator, the internal fistula opening was adequately closed by the clip. Eight months after clip closure the fistula had healed and the clip was removed using the OTSC® Proctology Clip Cutter. Fistula closure using the OTSC® Proctology system represents a promising sphincter-preserving minimally invasive procedure.

Abstract
<b><i>Hintergrund: </i></b>Nahtinsuffizienzen stellen eine gefürchtete Komplikation nach Operationen an der Speiseröhre dar, die mit hoher Morbidität und Mortalität vergesellschaftet sind. <b><i>Methoden: </i></b>Die Einlage komplett beschichteter Stents stellt die am häufigsten eingesetzte Methode zur Behandlung ösophagealer Leckagen dar. Eine neue endoskopische Therapiemodalität besteht mit der endoskopischen Vakuumschwammtherapie. Hierbei macht man sich die positiven Effekte des vakuumassistierten Verschlusses (Vacuum-Assisted Closure, V.A.C.), der eine etablierte Therapiemodalität zur Behandlung ausgedehnter infizierter Hautdefekte darstellt, zunutze. Durch neue Entwicklungen haben auch Clips (insbesondere der «Over-the-Scope-Clip», OTSC) wieder eine Bedeutung beim Verschluss von ösophagealen Nahtinsuffizienzen erhalten. <b><i>Ergebnisse: </i></b>Mit diesen endoskopischen Techniken lassen sich Nahtinsuffizienzen des Ösophagus in über 80% der Fälle erfolgreich verschließen. <b><i>Schlussfolgerung</i></b>: Endoskopische Techniken stellen eine geeignete Methode zum Verschluss ösophagealer Leckagen dar und konnten daher in den letzten 10 Jahren die chirurgische Revision weitestgehend verdrängen

Abstract
<b><i>Hintergrund: </i></b>Anastomoseninsuffizienzen stellen eine gefürchtete Komplikation der kolorektalen Chirurgie dar. Endoskopische Techniken haben sich in der Therapie der Leckagen zunehmend etabliert. In dieser Übersicht möchten wir einen Überblick der wichtigsten endoskopischen Verfahren geben. <b><i>Methode: </i></b>Systematische Recherche der vorhandenen Literatur. <b><i>Ergebnisse: </i></b>Die bedeutendsten endoskopischen Verfahren zur Behandlung der kolorektalen Anastomoseninsuffizienzen stellen die Fibrininjektion, die Vakuumschwammtherapie (Endo-Sponge), spezielle Clip-Systeme (OTSC) sowie die Stentimplantation dar. Der breiten klinischen Anwendung dieser Verfahren steht jedoch eine unzureichende Studienlage gegenüber. <b><i>Schlussfolgerung: </i></b>Die Einschätzung der Wertigkeit der einzelnen endoskopischen Verfahren untereinander und in speziellen therapeutischen Situationen hängt im Wesentlichen von der Erfahrung der Untersucher ab. Es bedarf der Durchführung randomisierter, prospektiver Studien, um diese Erfahrungen zu objektivieren.
