ABSTRACT
Objective: Lenvatinib is an oral multitarget tyrosine kinase inhibitor (mTKI) and is recommended for patients with advanced hepatocellular carcinoma (HCC) with Child-Pugh A liver function, who are not amenable to surgical resection, locoregional treatment, or transcatheter arterial chemoembolization. Hepatogastric fistula is a rare complication with a poor prognosis in patients with HCC. Previous reports on fistula formation during mTKI therapy for HCC were all associated with sorafenib. Here, we report the first case of recurrent hepatogastric fistula during lenvatinib therapy for advanced HCC managed using an over-the-scope clip (OTSC).Patient: We present the case of a 73-year-old man with alcoholic liver cirrhosis who was treated for multiple HCC for 7 years. HCC was treated using repetitive transcatheter arterial chemoembolization, radiofrequency ablation, and sorafenib. Owing to disease progression, lenvatinib treatment was started. During lenvatinib treatment, recurrent hepatogastric fistulas developed. An OTSC was useful for fistula closure and prevention of recurrence.Results: The major cause of fistula formation is considered to be the direct invasion of HCC; however, HCC treatment might also be a contributing factor in our case. In addition, OTSC was useful for fistula closure.Conclusion: Clinicians should be aware of the fatal complications during HCC treatment.
ABSTRACT
Objective To evaluate the therapeutic value of endoscopic jejunal tube placement, endoscopic clipping, and over the scope clip ( OTSC) for digestive fistula. Methods Data of 38 patients with digestive fistulas at the First Affiliated Hospital of Soochow University admitted from July 2015 to July 2017 were retrospectively analyzed. Treatments were chosen according to the size and the site of the fistulas. Thirteen patients underwent jejunal tube placement ( the jejunal tube group ) , 20 underwent endoscopic clipping( the endoscopic clipping group) , and 5 underwent OTSC( the OTSC group) . The technical success rate, clinical cure rate and postoperative hospital stay were analyzed. Results All patients received the endoscopic operation successfully with no significant complications. In the jejunal tube group, 4 patients′fistulas fully healed, lesion was smaller after treatment in 3 patients, lesion didn′t change in 5 patients, and 1 patient died. The complete cure rate was 30. 8％ (4/13), and the postoperative hospital stay was 47. 4± 14. 1 days. For the endoscopic clipping group, 16 patients′ fistulas fully healed, lesion was no smaller compared with that before treatment in 3 cases, and 1 patient died. The complete cure rate was 80. 0％ ( 16/20) , and the postoperative hospital stay was 17. 9 ± 8. 9 days. Total patients in the OTSC group were completely cured, with 100. 0％( 5/5) of complete cure rate. One patient with refractory esophageal fistula underwent OTSC repeatedly with endoscopic clipping, and the healing time of fistula was 102 days. The postoperative hospital stay of 4 others was 5. 3±1. 7 days. The cure rate of fistula was higher (P=0. 03, P<0. 001) and the postoperative hospital stay was shorter ( P=0. 04, P<0. 001) in the OTSC group compared with the clipping group and the jejunal tube group. Conclusion Endoscopic management is safe and effective for digestive fistulas with less trauma, easy performance and short time of healing.
ABSTRACT
BACKGROUND/AIMS: The Padlock clip is a recently introduced over-the-scope clip (OTSC) that requires the use of an alternate technique and has a different design from previous OTSCs. However, data regarding its clinical use are limited. The aim of this study is to present our clinical experience using this novel Padlock clip system.METHODS: Between September 2018 and June 2019, 7 consecutive patients underwent Padlock clip application at our center by an experienced endoscopist. A Padlock clip was used for achieving hemostasis in 4 patients presenting with gastrointestinal (GI) bleeding, as well as for endoscopic full-thickness resection in the remaining 3 patients.RESULTS: All 7 patients achieved technical as well as clinical success, with absence of complications or rebleeding, during a follow-up of a minimum of 3 weeks. All patients were hospitalized post procedure for a minimum of 48 hours, and an absence of adverse events was noted in our patient population throughout the procedure and post-procedure period. Antiplatelet therapy was reinstated shortly after the application of the Padlock clip, with no GI bleeding observed.CONCLUSIONS: The Padlock clip is a novel OTSC, with benefits that include safe, simple, and rapid deployment. Antiplatelet therapy may be reinstated for patients, when necessary, shortly after applying the Padlock clip due to full-thickness closure of the tissue.

Objective To evaluate the clinical efficacy and safety of different stitching methods,over-the-scope-clip (OTSC) and metal clips combined with nylon rope (King closure),for full-layer gastric wall defect.Methods Data of 75 cases,who underwent endoscopic full-thickness resection (EFTR) of gastric SMTs from May 2015 to May 2018 in our endoscopy center were retrospectively analyzed.According to the closure method,the patients were divided into the OTSC group (20 cases) and the King closure group (55 cases).Comparison was made in gender,age,the largest diameter of tumor,the location of tumor,defect surface diameter,total operating time,defect closure time,closure success rate,the length of hospital stays,cost and postoperative complications between the two groups,Results The baseline data were comparable,and there were no significant differences in age,gender,tumor location,tumor diameter,and defect surface diameter between the two groups(all P＞0.05).The success rate of closure was 100％ in both groups.In terms of length of hospital stay,there was no significant difference between the two groups (t =1.13,P=0.268).The total operating time was 63.24±43.22 min in the King closure group versus 47.60± 18.13 min in the OTSC group (t =2.20,P =0.030).The closure time of the defect surface was 20.85 ± 16.35 min in the King closure group versus 10.95±5.20 min in the OTSC group (t =2.65,P=O.010).Hospitalization costs were 24 200±800 yuan in the King closure group versus 36 200±2 350 yuan in the OTSC group (t=6.21,P＜0.001).Postoperative abdominal elevation radiographs in both groups indicated a small amount of subphrenic free gas,and no intervention was given due to the small amount of gas and no obvious symptoms.No late bleeding,recurrent perforation,infection or other complications occurred after operation,and all patients were discharged successfully.Six months after surgery,15 patients (27％) in the King closure group developed metal clips or nylon rope residue,which were successfully removed by endoscopy.The anastomosis clamp of nighteen patients (95％) in the OTSC group were in the original position.None of the patient received open surgery.Conclusion OTSC and King closure are both safe and effective in the treatment of full-thickness defect of gastric wall.OTSC has the advantages of short total operation time and short closure time,but with high cost.
ABSTRACT
Objective Gastrointestinal fistula is a serious complication after operation. It is reported that the over-the-scope-clip(OTSC) can close intestinal full-thickness wall and treat gastrointestinal fistula effectively. This study was to investigate the efficacy of OTSC in the treatment of gastrointestinal fistula.Methods We analyzed the clinical data of 28 postoperative patients with gastrointestinal fistula who underwent endoscopic closure using OTSC in Endoscopy Center of Research Institute of General Surgery in our hospital from October 2014 to October 2017, and recorded the course of disease, the site of gastrointestinal fistula, the diameter of fistula and the efficacy of OTSC. Patients with successful closure were followed up for half a year after hospital discharge to observe the recurrence of fistula.Results Endoscopic closure with OTSC was successful in all the 28 patients without complications like bleeding and falling off. In the sinus tract or digestive tract radiography at 1-2 weeks after OTSC closure, 23 patients were successful in endoscopic closure(82.14%). In the six months′ follow-up of 23 patients with successful treatment, 4 patients were lost to follow-up and 19 patients were successful without recurrence of fistula.Conclusion The endoscopic closure of gastrointestinal fistula using OTSC is safe and effective, avoiding reoperation and reducing trauma.

ABSTRACT
BACKGROUND/AIMS: Currently, a new over-the-scope clip (OTSC) system has been introduced. This system has been used for gastrointestinal perforations and fistulas in other countries. The aim of our study is to examine the therapeutic success rate of endoscopic treatment using the OTSC system in Korea. METHODS: This was a multicenter prospective study. A total of seven endoscopists at seven centers performed this procedure. RESULTS: A total of 19 patients were included, with gastrointestinal leakages from anastomosis sites, fistulas, or esophageal perforations due to Boerhaave’s syndrome. Among these, there were three gastrojejunostomy sites, three esophagojejunostomy sites, four esophagogastrostomy sites, one esophagocolonostomy site, one jejuno-jejunal site, two endoscopic full thickness resection site closures, one Boerhaave’s syndrome, two esophago-bronchial fistulas, one gastrocolonic fistula, and one colonopseudocyst fistula. The size of the leakage ranged from 5 to 30 mm. The median procedure time was 16 min. All cases were technically successful. Complete closure of the leak was achieved in 14 of 19 patients using OTSC alone. CONCLUSIONS: The OTSC system is a safe and effective method for the management of gastrointestinal leakage, especially in cases of anastomotic leakage after surgery.

The full-thickness resection device (FTRD) is a novel endoscopic device approved for the resection of colorectal lesions. This case-series describes the device and its use in high-risk patients with colorectal lesions and provides an overview of the potential indications in recently published data. Between December 2014 and September 2015, 3 patients underwent endoscopic full thickness resection using the FTRD for colorectal lesions: 1 case for a T1 adenocarcinoma in the region of a surgical anastomosis after recto-sigmoidectomy, 1 case for a non-lifting colonic adenoma with low-grade dysplasia in an 89-year old patient and 1 for a recurrent adenoma with high-grade dysplasia in a young patient with ulcerative rectocolitis who was under immunosuppression after renal transplantation. Both technical and clinical success rates were achieved in all cases. The size of removed lesions ranged from 9 to 30 mm. Overall, the most frequent indication in the literature has been for lifting or non-lifting adenoma, submucosal tumors, neuroendocrin tumors, incomplete endoscopic resection (R1) or T1 carcinoma. Colorectal FTRD is a feasible technique for the treatment of colorectal lesions and represents a minimally invasive alternative for either surgical or conventional endoscopic resection strategies.

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.

Gastrointestinal (GI) bleeding is a common complication after heart assist device placement. Reasons for bleeding are multifactorial. Endoscopic therapy is the treatment of choice, whereas invasive procedures are avoided in these critically ill patients. We present the case of a 65-year-old male patient experiencing severe GI bleeding after left ventricular assist device (LVAD) and right ventricular assist device (RVAD) placement with therapeutic anticoagulation. Endoscopically, multiple gastric bleeding sources were found but could not be treated effectively due to a large blood clot. A combined endoscopic and surgical treatment was initiated, including gastrotomy for blood clot removal, surgical transgastric suturing, endoscopic over-the-scope clip (OTSC) placement and hemospray application. Postoperative endoscopic visualization showed effective bleeding control. The patient unfortunately died due to causes unrelated to the treatment. This case shows that a minimal invasive combination of endoscopic and surgical techniques can be an alternative treatment for severe upper GI bleeding in critically ill and anticoagulated patients.

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.

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.
