Background and aim:  Strictures are a major complication of esophageal endoscopic submucosal dissection (ESD) for superficial esophageal carcinoma. Post ESD, stricture develops during the process of scar formation, which is related to inflammation caused by ESD. We planned a study to evaluate whether certain electrosurgical unit modes could attenuate strictures after esophageal ESD. Methods:  A total of 16 ESD, three-quarters of the esophageal circumference, were performed in four live pigs...

Background and study aims:  Heterotopic pancreas is a common subepithelial lesion in the stomach. However, its histological diagnosis is difficult when tissue samples are obtained with a conventional biopsy forceps. This study aimed to describe the magnifying endoscopy with narrow-band imaging (ME-NBI) features of gastric heterotopic pancreas. Patients and methods:  We retrospectively analyzed a database of all patients who underwent endoscopic ultrasonography (EUS) at Pusan National University Hospital from January 2010 to December 2010...

Background and study aims:  Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) in malignant gastric outlet obstruction (GOO) appears to be promising; however, its role in benign GOO is unclear. The aim of this study was to ascertain the clinical efficacy and safety of EUS-GE in benign GOO. Patients and methods : This was an international retrospective series involving 5 tertiary centers. Consecutive patients who underwent EUS-GE between 1/2013 - 10/2016 for benign GOO were included...

Background and study aims:  Endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) or biopsy (FNB) is an indispensable diagnostic tool. Improvements in needling technique have led to increasing tissue yields. Blood clogging of the needle can cause difficulties with specimen handling and stylet passage, which improves when the needle is primed with heparin before use. However, the effect of heparin on cytology, histology or immunochemistry (IHC) of FNA and FNB specimens is unknown...

Background and study aims  A 70-year-old-man underwent an esophagectomy and posterior mediastinal reconstruction for esophageal cancer that was curatively resected. Although the patient was allowed to eat after surgery, he repeatedly vomited after drinking water or eating meals and required continuous hospitalization. An upper gastrointestinal series and endoscopic examination revealed an obstruction due to the flexure of the gastric conduit, which was repeatedly treated with endoscopic balloon dilation. Endoscopic balloon dilation was completely ineffective, however, because the obstruction was not due to a small lumen diameter, but rather to severe flexure...

Background and study aims:  Colorectal cancer (CRC) is one of the most common neoplasms and endoscopic submucosal dissection (ESD) is an effective treatment for early-stage CRC. However, it has been observed that patients undergoing ESD often complain of pain, even if ESD has been successfully performed. Risk factors for such pain still remain unknown. The aim of this study was to explore the risk factors for post-colorectal ESD coagulation syndrome (PECS). Patients and methods : This was a prospective multicenter observational trial (UMIN000016781) conducted in 106 of 223 patients who underwent ESD between March 2015 and April 2016...

Benign colonic anastomotic stenosis sometimes occurs after surgical resection and usually requires surgical or endoscopic dilation. Limited data are available on the effectiveness and safety of the endoscopic radial incision and cutting (RIC) method at sites other than the esophagus. The aim of this retrospective study was to investigate the effectiveness and safety of RIC dilation for severe benign anastomotic colonic stenosis. Subjects were 3 men (median age 72 years, range 65 - 76 years) who developed severe benign anastomotic stenosis after surgical resection for colorectal carcinoma and were subsequently treated by RIC dilation at Hiroshima City Asa Citizens Hospital between May 2014 and December 2016...

Background and study aims:  Although new image-enhanced endoscopy (IEE) technologies such as blue laser imaging (BLI), BLI-bright, and linked color imaging (LCI) have been developed, their utility for the detection of sessile serrated adenoma/polyps (SSA/Ps) is still unclear. This study aimed to evaluate the utility of BLI, BLI-bright, and LCI for SSA/P detection in still image examinations and in a prospective randomized controlled trial (RCT). Patients and methods:  A group of 6 expert and non-expert endoscopists read 200 endoscopic still images containing SSA/P lesions using white light image (WLI), BLI, BLI-bright, and LCI...

Background and study aims:  Capsule endoscopy (CE) has become a routine means of diagnosing obscure gastrointestinal bleeding (OGIB) in the small intestine. Capsules using novel blue-enhanced white light-emitting diodes are expected to acquire clearer contrast images (CIs) of the small bowel vasculature. We conducted a pilot study to examine whether CIs facilitate visualization of small bowel erosions, ulcers, and areas of angioectasia compared with standard white light images (WLIs)...

Background and study aims  We describe a case of perforation after colonic endoscopic mucosal resection (EMR) that was treated conservatively. We would like to highlight the importance of decision-making mainly based on the endoscopist's point of view in combination with the surgical consultation. Although the radiological imaging is always needed, it cannot solely lead to a decision for operation. Intraperitoneal gas in computed tomography is not always associated with a hole in the endoscopic field and could be possibly explained from a "balloon" phenomenon...

Background:  Adherence to quality indicators and surveillance guidelines in the management of Barrett's esophagus (BE) promotes high-quality, cost-effective care. The aims of this study were (1) to evaluate adherence to standardized classification (Prague Criteria) and systematic (four-quadrant) biopsy protocol, (2) to identify predictors of practice patterns, and (3) to assess adherence to surveillance guidelines for non-dysplastic BE (NDBE). Methods:  This was a single-center retrospective study of esophagogastroduodenoscopy (EGD) performed for BE (June 2008 to December 2015)...

Background and study aims:  Polypoid lesions found during upper gastrointestinal endoscopy (UGIE) are occasionally found in patients with portal hypertension (PH). This study aimed to assess the true nature of such polypoid lesions using endoscopic ultrasound (EUS) and determine the accuracy of UGIE in differentiating between vascular and non-vascular lesions in PH. Patients and methods:  We retrospectively assessed all patients with PH referred for EUS due to polypoid lesions of unknown nature at UGIE over a 7-year period...

Background and study aims:  Rectosigmoidoscopy with biopsy has been regarded to be a useful procedure to diagnose gastrointestinal graft-versus-host disease (GVHD). However, little is known about the specific colonoscopic features of gastrointestinal GVHD. In this study, we focused on the 4 unique colonoscopic findings - orange peel appearance, spotty redness, small mucosal sloughing, and diffuse mucosal defect - which are possible specific findings of gastrointestinal GVHD. We aimed to estimate the usefulness of these four unique colonoscopic findings in the rectosigmoid portion to diagnose gastrointestinal GVHD...

Background and study aims  Endoscopic drainage of walled-off pancreatic necrosis (WOPN) is feasible when contact with the gastric or duodenal wall is present; when WOPN cannot be accessed endoscopically, a percutaneous approach can be considered. Percutaneous use of esophageal self-expandable metal stents (SEMS) to establish access to a WOPN cavity was evaluated.

Background and study aims  Endoscopic retrograde cholangiopancreatography (ERCP) is an invasive diagnostic and interventional procedure used in conditions related to the pancreas and biliary tract. It has a complication rate ranging from 4 % to 10 %. Severe complications are few with the most common of them being post-ERCP pancreatitis, post-sphincterotomy bleeding, and perforation. A rare, but potentially life-threatening complication of ERCP is splenic injury. We report the case of a 60-year-old female with choledocholithiasis who sustained splenic decapsulation following ERCP...

Introduction and study aims:  Gastric antral vascular ectasia (GAVE) is a mucosal abnormality associated with multiple conditions, most notably cirrhosis and systemic sclerosis, that causes indolent gastrointestinal bleeding. It is primarily managed with endoscopic therapy. Traditionally, GAVE is endoscopically ablated using argon plasma coagulation (APC) but radiofrequency ablation (RFA) is emerging as an alternative modality. No prior comparison of the 2 modalities has been published...
