BACKGROUND AND AIMS: Mucosal traction as a "second hand" in endoscopic submucosal dissection (ESD) is very helpful for ESD operators. The efficacy of using a snare combined with endoclips to assist in ESD (SC-ESD) was evaluated whether it could achieve peroral external traction (PET) and internal traction (PIT) and real-time adjustment of mucosal traction position. This study aimed to preliminarily evaluate its feasibility. METHODS: A snare was fixed using endoclips to the incised mucosal flap that was intended for dissection...

Background and study aims  This is a case report on use of the CryoBalloon as a salvage technique for ablation of residual neoplasia at an endoscopic mucosal resection site. The site contained an embedded clip that could not be removed at two different sessions by three experienced endoscopists. On follow-up endoscopy, the clips and residual polyp no longer remained. The subtle scar that was present was biopsied and confirmed complete eradication of neoplasia and no polyp tissue. This case shows the potential of the CryoBalloon to ablate unwanted tissue outside of the esophagus...

BACKGROUND: Serious complications due to perforation restrict the development of duodenal endoscopic treatment. The key stage for remediation is the successful endoscopic closure to prevent peritonitis and the need for surgical intervention. This report aimed to present a new simple method for the closure of large iatrogenic duodenal perforations with purse-string sutures using the novel endoloops and repositionable clips through a single-channel endoscope. METHODS: A total of 23 patients with iatrogenic duodenal perforations ≥ 1 cm were retrospectively studied who were presently treated by purse-string sutures using the novel endoloops and the repositionable hemostasis clips with the single-channel endoscope at four institutes...

Metal endoclips are frequently utilized in surgical procedures. Within the medical literature, metal endoclip migration following general surgical procedures is a widely studied complication. However, examples of thoracic metal endoclip migration are, as yet, absent in the medical literature. This case study seeks to provide the first clear example of such thoracic metal endoclip migration.

AIM: To prospectively investigate the efficacy and safety of clip-flap assisted endoscopic submucosal dissection (ESD) for gastric tumors. METHODS: From May 2015 to October 2016, we enrolled 104 patients with gastric cancer or adenoma scheduled for ESD at Shiga University of Medical Science Hospital. We randomized patients into two subgroups using the minimization method based on location of the tumor (upper, middle or lower third of the stomach), tumor size (< 20 mm or > 20 mm) and ulcer status: ESD using an endoclip (the clip-flap group) and ESD without an endoclip (the conventional group)...

We describe a patient with a giant Brunner's gland hamartoma in the duodenum who was safely treated by endoscopic mucosal resection (EMR). A 64-year-old woman visited our hospital for a workup of severe anaemia (haemoglobin level: 5 g/dL). Oesophagogastroduodenoscopy revealed a large pedunculated and elongated polypoid lesion measuring approximately 70 mm in longitudinal diameter, located at the anterior wall of the duodenal bulb. We diagnosed her as having gastrointestinal bleeding originating from this lesion...

BACKGROUND: Although the use of endoscopic submucosal dissection (ESD) as a minimally invasive treatment for large superficial colorectal neoplasms is increasing, colorectal ESD remains technically challenging. As perforation in the colorectum is generally considered to be associated with a higher risk of complications, the aim of this study was to investigate the characteristics of perforation caused by colorectal ESD. METHODS: This retrospective study included 635 lesions treated with colorectal ESD, between February 2011 and December 2015, in a tertiary cancer center...

Duodenal perforation due to biliary stent migration is rare, and it often requires surgical repair; however, endoscopic closure has recently become a viable option in the appropriate patients. We present the case of a 79-year-old female who underwent biliary stent placement for a common bile duct stricture, who subsequently was found to have a duodenal wall perforation secondary to stent migration. The stent was extracted endoscopically with successful defect closure using a ConMed® repositional DuraClip™...

Complications related to cholecystectomy occur in <3% of patients. Endoclip migration after laparoscopic cholecystectomy with hepatolithiasis is an extremely rare complication. We report a case of hepatolithiasis secondary to endoclip migration after laparoscopic cholecystectomy treated successfully via right hepatectomy. A 35-year-old female presented with upper abdominal pain, fever and vomiting 9 years after laparoscopic cholecystectomy for chronic calculus cholecystitis. Laboratory investigation revealed gamma-glutamyl transpeptidase of 550 U/L and alkaline phosphatase of 350 U/L...

Cricopharyngeal myotomy with flexible endoscope is a well-known and safe treatment for Zenker's diverticulum. We describe hereafter how we perform this flexible endotherapy. From January 2011 to January 2017, we treated 28 patients with this endotherapy. Our technique is described step-by-step in the paper: the main principle is to perform an endoscopic cut of the diverticular septum and cricopharyngeal muscle's fibers (see the video). We describe an objective measurement of the cutting length and depth of the myotomy...

PURPOSE: Not all endoscopically placed clips (endoclips) are magnetic resonance imaging (MRI) compatible. At many institutions, endoclip screening is part of the pre-MRI screening process. Our objective is to determine the contribution of each step of this endoclip screening protocol in determining a patient's endoclip status at our institution. METHODS: A retrospective review of patients' endoscopic histories on general MRI screening forms for patients scanned during a 40-day period was performed to assess the percentage of patients that require endoclip screening at our institution...

Flexible endoscopy has developed from a diagnostic tool for tissue biopsy sampling to a treatment tool for endoscopic resection of neoplasms in the digestive tract. In the near future, one of the advanced endoscopic techniques, endoscopic full-thickness resection (EFTR), is expected to be a feasible endoscopic procedure. In the present review, systematic review of conventional exposed EFTR was carried out. Search queries were (endoscopic full-thickness resection or EFTR) (over-the-scope clip or OTSC) (Overstitch System) from 2015 to 2017...

Background and study aims : The adequate visualization of the dissection line, inside the submucosal layer, supposes the main challenging issue in ESD. For this reason, several counter traction methods have been developed focused on overcoming this handicap. One of which, Magnetic anchor guided - ESD (MG-ESD) is an attractive alternative. However, the usefulness of this approach has been scarcely assessed and compared with other ESD strategies. Therefore, the aim of this study is to compare three different ESD alternatives in experimental faction...
