A M Ahmed, C M Wilcox
Golf and endoscopic retrograde cholangiopancreaticography (ERCP) share a commonality where the highs of the successes are balanced by the lows of the frustrations. ERCP cannulation is one of the most difficult maneuvers in gastrointestinal endoscopy and is a requirement for the procedure's therapeutic benefit. As such, many different techniques have been developed to facilitate cannulation. The mission of the procedure is to provide access to the biliary or pancreatic duct typically with a guidewire, which can then be utilized as a platform for therapeutic and diagnostic procedures...

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 GI tract. We hereby report a series of patients with post pancreaticogastrostomy occuring pancreatic fistula in whom OTSCs were used as endoscopic treatment. METHODS: We prospectively collected data from January 2012 to July 2015 about cases of postoperative pancreatic fistula...

Jain et al. commented on the advantages of remote transmission of live demonstrations by experts from their own hospital. This practice eliminates many of the conventional problems with live demonstrations. They point, however, to the possible pressure on operators to demonstrate a specific procedure at a "scheduled time". We believe that all staff involved have a responsibility to ensure the procedure is safe for the patient and educational for the audience. This article is protected by copyright.

BACKGROUND AND AIMS: Endoscopic retrograde cholangiography (ERCP) with biliary stenting for the treatment of unresectable malignant biliary obstruction (MBO) is challenging among patients with surgically altered anatomy. Endoscopic ultrasound-guided antegrade biliary stenting (EUS-ABS) was introduced as an alternative biliary drainage method, although it has not been well studied yet. In this single-center prospective pilot study, we aimed to evaluate the feasibility and safety of EUS-ABS for MBO in patients with surgically altered anatomy...

REVIEW
J Y Y Wong, P Kongkam, K Y Ho
Training of endoscopic ultrasound (EUS) in Asia faces two major challenges: (i) the ever-increasing demand for skills to handle a growing range of interventional EUS procedures; and (ii) a continual shortage of EUS training programs. As the therapeutic application of EUS continues to expand,(1, 2) the need to train more new endosonographers and upgrade skills of existing ones has become more critical than ever before. A formal fellowship to acquire EUS knowledge and skills in an advanced endoscopy centre has always been perceived as the best way of training novices, but such opportunities remain limited in most Asian countries...

BACKGROUND AND AIM: The significance of examination time of esophagogastroduodenoscopy (EGD) for asymptomatic examinees is yet to be established. We aimed to clarify whether endoscopists who allot more examination time can detect higher numbers of neoplastic lesions among asymptomatic examinees. METHODS: We reviewed a database of consecutive examinees who underwent EGD in our hospital from April 2010 to September 2015. Staff endoscopists were classified into fast, moderate, and slow groups based on the mean examination time of EGD without a biopsy...

BACKGROUND AND AIM: The risk of developing colorectal cancer is higher in patients with ulcerative colitis (UC) than in the general population. Guidelines recommend surveillance colonoscopy (SCS) to reduce mortality; however, few studies have assessed physicians' adherence to guidelines. This study was aimed to clarify the current status of SCS and adherence to guidelines through the characteristics of cancer/dysplasia surveillance for UC patients in Japan. METHODS: A questionnaire was mailed to 541 physicians who attended meetings on inflammatory bowel disease...

A 69-year-old woman with no significant medical history presented with abdominal pain and frequent vomiting. Laboratory investigation revealed microcytic anemia (hemoglobin 10.1 mg/dL, mean corpuscular volume 79 fL). Contrast-enhanced computed tomography showed small bowel obstruction. Her symptoms were relieved after transnasal ileus tube insertion. The tube was removed four days later. She remained asymptomatic after she resumed eating. Esophagogastroduodenoscopy and colonoscopy showed no abnormal findings...

A 32-year-old man underwent wireless capsule endoscopy (WCE) (OMOM Capsule Endoscopy, Jinshan Science & Technology Company, Chongqing, China) for detecting obscure gastrointestinal bleeding 7.5 years ago. The result of WCE did not reveal any hemorrhagic focus, diverticulum or other abnormal changes of the gastrointestinal tract until its battery exhausted. The man then moved out from the area and lost to follow up without a report of capsule excretion. For confirming the diagnosis of recurrent melena and iron-deficiency anemia, the patient came to our clinical center...

Gastric outlet obstruction (GOO) which can be caused by benign and malignant diseases often leads to a reduction in patient quality of life. Lately endoscopic ultrasonography (EUS)-guided gastroenterostomy (EUS-GE) has emerged. At the present time, there are three types of EUS-GE using lumen-apposing biflanged metal stents (LAMS), i.e., direct EUS-GE, assisted EUS-GE using retrieval/dilating balloon, single balloon overtube, nasobiliary drain and untraslim endoscope, and EUS-guided double balloon occluded gastrojejunostomy bypass (EPASS)...

REVIEW
Tiing Leong Ang, Anthony Yuen Bun Teoh
Endoscopic ultrasound (EUS)-guided drainage is now firmly established as the best option for drainage of walled-off pancreatic fluid collections (PFC). It has high clinical efficacy, similar to surgical and percutaneous approaches, but with lower morbidity and costs. It is superior to non-EUS guided approaches because even collections without endoluminal bulging can be successfully drained. Transmural drainage alone is sufficient for pseudocysts, but in the context of walled-off pancreatic necrosis (WON), adjunctive direct endoscopic necrosectomy (DEN) may be required...

OBJECTIVES: Endoscopic procedures are used as first-line treatment for bile leak after hepatobiliary surgery. Advances have been made in endoscopic techniques and devices, but few reports have described the effectiveness of endoscopic procedures and the management principles based on the severity of bile leak. We evaluated the effectiveness of an endoscopic procedure for the treatment of bile leak after hepatobiliary surgery. METHODS: Fifty-eight patients underwent an endoscopic procedure for suspected bile leak after hepatobiliary surgery; the presence of bile leak on endoscopic retrograde cholangiopancreatography (ERCP) was evaluated retrospectively...

OBJECTIVES: In recent years, knowledge concerning the mechanical properties of self-expandable metallic stents (SEMS) has increased. In a previous study, we defined traction force and traction momentum and reported that these characteristics are important for optimal stent deployment. However, traction force and traction momentum were represented as relative values and were not evaluated in various conditions. The purpose of this study was to measure traction force in various situations assumed during SEMS placement...

Pancreatic juice cytology using endoscopic nasopancreatic drainage (ENPD) has been reported as an useful method for making diagnosis of early pancreatic carcinoma. (1-3) Here, we present a patient whose nasopancreatic drainage tube was entrapped; nevertheless, the tube was successfully retrieved endoscopically. A 71-year-old man was admitted for investigation of a focal main pancreatic duct (MPD) stricture. This article is protected by copyright. All rights reserved.

We read with interest the meta-analyses by Feng et al (1) and by Inamdar et al (2) , objecting to the use of rectal indomethacin for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) prophylaxis in "average-risk patients" and in general patients, respectively, through analysing the same six randomized controlled trials (RCT) where patients were unselected. Inamdar et al defined "average-risk patients" as patients not meeting criteria for high-risk patients for PEP. (2) However, five RCTs in the meta-analysis included a proportion of high-risk patients...

Systemic vasculitis can present with a variety of symptoms and signs(1, 2) . Some cases may be confused with cancer(3) . We herein describe the case of esophagitis caused by vasculitis. A 79-year-old male with mild dysphagia who was suspected with esophageal cancer at a previous hospital was referred to our facility. Upper GI endoscopy, which was undergone at our hospital, revealed a circumferentially elevated lesion with ulceration (Fig. 1a). This article is protected by copyright. All rights reserved.

OBJECTIVES: Self-expandable metal stents (SEMSs) are utilized for nonresectable malignant gastric outlet obstruction (GOO). Studies of covered vs. uncovered SEMSs have yielded inconsistent results due to heterogeneity in designs and patient populations. We performed a meta-analysis to compare covered and uncovered gastroduodenal SEMSs. METHODS: Using MEDLINE, Embase, and the Cochrane database, we identified 1,624 patients from 13 prospective and retrospective studies which evaluated covered and uncovered SEMSs for malignant GOO and were published until October 2016...
