BACKGROUND/AIM: Endoscopic access to the common bile duct remains difficult in 10% of cases undergoing endoscopic retrograde cholangiopancreaticography (ERCP). In the current study, we evaluated the effectiveness of a stiff-shaft and flexible-tip guidewire (Visiglide2(®) ) for selective biliary access. METHODS: We conducted a prospective, randomized controlled study involving patients with a naïve papilla who required biliary cannulation in a single center. We randomly allocated the patients to the Visiglide 2 group (Group V) or conventional guidewire group (Group C)...

OBJECTIVES: Although several drugs may induce small-bowel mucosal injuries, it is unclear whether these injuries contribute to overt small-bowel bleeding. This study was designed to evaluate the associations between drug use and small-bowel mucosal injury and between these mucosal injuries and overt bleeding in a disease-relevant population. METHODS: We retrospectively studied patients with suspected small-bowel diseases who underwent capsule endoscopy between 2010 and 2013...

EDITORIAL
C Mel Wilcox
In this issue of the Journal, Professor Elmunzer provides an outstanding overview of the variable methods of prevention of post-ERCP pancreatitis (PEP) (1). We all recognize the importance of this topic given its morbidity for our patients. His review succinctly summarizes a wealth of both old and new data underscoring previously identified risk factors for PEP which have stood the test of time. In addition, newer interventions are appraised and placed in an appropriate context. This article is protected by copyright...

REVIEW
Tom G Moreels
This review provides an update of the currently available (proto-) types of device-assisted enteroscopy (DAE). In recent years, newly designed double- and single-balloon enteroscopes have emerged. They aim to improve insertion depth into the small bowel, and they also allow more efficient endoscopic interventions. Nowadays, almost all conventional endoscopic procedures are feasible using DAE, opening the door to new indications. Recently, more data have become available on paediatric DAE, DAE-assisted colonoscopy, and DAE in patients with altered anatomy, including DAE-assisted ERCP and direct cholangioscopy...

BACKGROUND: The treatment for achalasia has traditionally been Heller myotomy (HM). Despite its excellent efficacy rate, a number of patients remain symptomatic post-procedure. Limited data exists as to the best management for recurrence of symptoms post HM. We present an international, multicenter experience evaluating the efficacy and safety of post-HM per-oral endoscopic myotomy (POEM). METHODS: Patients who underwent a POEM post-HM from 13 centers from January 2012 to January 2017 were included as part of a prospective registry...

OBJECTIVES: In Japan, an increase in the number of routine esophagogastroduodenoscopy procedures is expected because several studies have reported that endoscopy screenings have reduced gastric cancer mortality. Magnifying narrow-band imaging has been reported to be effective for accurate diagnosis of gastric abnormalities such as cancers, adenomas, and intestinal metaplasia. However, the efficacy of this method in routine esophagogastroduodenoscopy has not been clarified. METHODS: We divided 3,763 patients into two groups...

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has become crucial for the management of pancreatic tumors(1) . Liquid-based cytology (LBC) has proven to be effective for the cytopathological characterization of several malignancies; however, its value in the approach of pancreatic neoplasms is not fully established yet(2-4) . With great interest, we carefully read the retrospective study conducted by Hashimoto and colleagues, which reported higher sensitivity and accuracy rates with LBC for diagnosing pancreatic ductal adenocarcinoma (PDAC) when compared to conventional smear (CS)(5) ...

Aluminum potassium sulfate and tannic acid (ALTA) sclerotherapy is a minimally invasive treatment for internal hemorrhoids with few complications. However, it may occasionally induce complications such as rectal ulcer. The use of polyglycolic acid (PGA) sheets to seal hemorrhagic rectal ulcers is rare. We report the successful treatment of hemorrhagic rectal ulcer caused by ALTA sclerotherapy using PGA sheets. This article is protected by copyright. All rights reserved.

OBJECTIVES: In Western countries ESD (Endoscopic Submucosal Dissection) has not prevailed due to training issues and a target patient population. We reported a hybrid ESD technique, SEMR (submucosal endoscopy with mucosal resection), in which the submucosal dissection is performed chiefly by blunt balloon dissection. We have reported successful application in the porcine colon. In this study we compared the safety and efficacy between SEMR with ESD in the porcine esophagus and stomach...

We appreciate the comments of Dr. Koksal and co-workers on our recent article. In brief, we reported on two first patients with benign biliary strictures treated with self-expanding poly-dioxanone biodegradable biliary stents (BDBS) inserted in endoscopic retrograde cholangiography (ERC). The authors underline that BDBS may cause epithelial hyperplasia in the bile duct similarly to oesophageal use. This article is protected by copyright. All rights reserved.

A man in his seventies underwent esophagogastroduodenoscopy, which revealed a 30-mm whitish protruding lesion at the descending part of the duodenum. Owing to the protrusion and reddish depressed area on the lesion, invasive cancer was suspected (Fig. 1A). Endoscopic ultrasonography (EUS) with a 20-MHz miniature probe (UM-3R, Olympus Medical Systems, Tokyo, Japan) revealed an intramucosal hypoechoic lesion and a thickened high echoic submucosal layer with acoustic attenuation (Fig. 1B).

INTRODUCTION: The main treatment aim in chronic pancreatitis (CP) is symptom control and especially pain relief. Management of stone-predominant CP is challenging and requires a multidisciplinary approach. Extracorporal shock wave lithotripsy (ESWL) has emerged as the cornerstone of non-surgical treatment due to disappointing results of available endoscopic treatment options during the last decades. With new developments in the field of direct peroral pancreatoscopy (POP) and intracorporal lithotripsy, direct intraluminal treatment of main pancreatic duct (MPD) stones returns into spotlight...

REVIEW
Kosuke Minaga, Masayuki Kitano
Endoscopic ultrasound-guided biliary drainage (EUS-BD) is increasingly used as an alternative in patients with biliary obstruction who fail standard endoscopic retrograde cholangiopancreatography (ERCP). The two major endoscopic approach routes for EUS-BD are the transgastric intrahepatic and transduodenal extrahepatic approaches. Biliary drainage can be achieved by three different methods, transluminal biliary stenting, transpapillary rendezvous technique, and antegrade biliary stenting. The choice of approach route and drainage method depends on individual anatomy, underlying disease, and location of the biliary stricture...

REVIEW
B Joseph Elmunzer
Pancreatitis is the most common and potentially devastating complication of endoscopic retrograde cholangiopancreatography (ERCP), resulting in significant morbidity, occasional mortality, and increased health-care expenditure. Accordingly, the prevention of post-ERCP pancreatitis (PEP) remains a major clinical and research priority. Strategies to reduce the incidence of PEP include thoughtful patient selection, appropriate risk-stratification, sound procedural technique, prophylactic pancreatic stent placement, and pharmacoprevention...

We read the article entitled 'Endoscopic biodegradable biliary stents in the treatment of benign biliary strictures: First report on clinical use in patients' by Siiki et al with great interest (1). The authors successfully treated two patients with benign biliary strictures, possibly due to choledocholithiasis, with endoscopic insertion of polydioxanone biodegradable biliary stents. They reported that the treatment was uneventful and the stents were completely dissolved between 3 and 6 months without leaving a sequela in the bile ducts...

BACKGROUND AND AIMS: The differential diagnosis of localized gallbladder lesions is challenging. The aim of this study was to evaluate the utility of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) for diagnosis of localized gallbladder lesions. PATIENTS: One hundred and twenty-five patients with localized gallbladder lesions were evaluated by CH-EUS between March 2007 and February 2014. This was a single-center retrospective study. METHODS: The utilities of fundamental B-mode EUS (FB-EUS) and CH-EUS in the differentiation of gallbladder lesions and sludge plug were initially compared...

OBJECTIVES: In patients with irretrievable or intractable bile duct stone, temporary insertion of plastic stent (PS) followed by further ERCP or surgery has been recommended as a "bridge" therapy. However, the exact mechanism of stone fragmentation has not been discovered. The aim of this study was to evaluate whether PS shape can facilitate stone fragmentation. METHODS: Using a new in vitro bile flow phantom model, we compared the friction effect among the three different PS groups (straight PS group; double pigtail-shaped PS group, and screw-shaped PS group) and the control group...

Confocal laser endomicroscopy (CLE)(1)) and endocytoscopy system (ECS)(2)) have made optical biopsy in the digestive tract a reality. However, for omission of biopsy histology, visualization of nuclei is essential. In ECS, nuclei can be observed after vital staining with methylene blue, toluidine blue etc.(3)) , and vital staining in CLE requires venous injection or spraying of fluorescein into the gastrointestinal lumen(4)) . However, fluorescein does not stain nuclei. Acriflavin, a topical antiseptic drug, can stain nuclei for CLE observation(5)) , but it has not been widely used because of associated adverse events...

A 76-year-old man with positive fecal occult blood tests underwent colonoscopy, which revealed a laterally spreading tumor completely surrounding a diverticulum in the ascending colon. He was referred to our hospital for further examination and treatment. A second colonoscopy revealed that the laterally spreading tumor involved an entire diverticulum in the posterior wall of the ascending colon. This article is protected by copyright.
