Esophageal neuroendocrine carcinoma (NEC) is rare1 and often progresses rapidly with poor prognoses2,3 . A 75-year-old woman showed a 20-mm reddish depressed lesion, with central elevation and apparent wall extensions in her middle thoracic esophagus on esophagogastroduodenoscopy (Fig 1A, B).

Endoscopic dilation for severe benign biliary stricture using mechanical dilation devices is occasionally ineffective. Hence, diathermic dilation has recently been gaining attention as a salvage procedure. We evaluated the short- and long-term outcomes of diathermic dilation for severe benign biliary stricture that could not be dilated using the conventional mechanical dilation. 13 consecutive cases with severe benign biliary stricture that underwent diathermic dilation using 6-Fr electrocautery dilator were enrolled...

OBJECTIVES: To analyze factors of procedural failure and to discuss responses to procedural failure, by using the outcomes of endoscopic retrograde cholangiopancreatography (ERCP), performed using a short-type single-balloon enteroscope (short SBE) in patients with surgically altered gastrointestinal anatomy. METHODS: The study sample included patients who underwent ERCP-related procedures using a short SBE, between September 2011 and September 2018, at our hospital...

A 63-year-old man with a history of alcoholic pancreatitis presented to our hospital with dyspnea. Chest X-ray demonstrated pleural effusion (Fig. 1a), and magnetic resonance cholangiopancreatography (MRCP) revealed that the pancreatic pleural effusion was connected with a pancreatic pseudocyst via the mediastinum (Fig. 1b). His symptom improved by tube drainage of the left pleural effusion. This article is protected by copyright. All rights reserved.

Takagi et al. reported that differentiation between isolated IgG4-related sclerosing cholangitis (IgG4-SC showing no association with autoimmune pancreatitis) and Klatskin tumor is difficult because both appear as nodular lesions (1). They concluded that cholangiographic findings with symmetrical smooth long stricture extending into the upper bile duct This article is protected by copyright. All rights reserved.

OBJECTIVES: Septal thickness (ST) can predict a malignant branch duct (BD) and mixed type intraductal papillary mucinous neoplasm (IPMN) of the pancreas, but its cut-off value has not been established. The aim was to determine the optimal ST cut-off value to predict malignancy using endoscopic ultrasound (EUS). METHODS: We retrospectively identified 200 patients with IPMN, including 132 with BD- and mixed-IPMN, who underwent surgical resection between 1989 and 2017...

OBJECTIVES: Endoscopic ultrasound-guided biliary drainage (EUS-BD) can be performed via two different approaches: choledochoduodenostomy (CDS) and hepaticogastrostomy (HGS). We compared the efficacy and safety of these approaches in malignant distal biliary obstruction (MDBO) patients using a prospective, randomized clinical trial. METHODS: MDBO patients after failed ERCP were randomly selected for either CDS or HGS. The procedures were performed at nine tertiary centers from September 2013 to March 2016...

REVIEW
Yu Sen Alex Soh, Yeong Yeh Lee, Takuji Gotoda, Prateek Sharma, Khek-Yu Ho, Asian Barrett's Consortium
Barrett's Esophagus (BE), a premalignant condition of the lower esophagus, is increasingly prevalent in Asia. However, endoscopic and histopathogical criteria vary widely between studies across Asia, making it challenging to assess comparability between geographical regions. Furthermore, guidelines from various societies worldwide provide differing viewpoints and definitions, leading to diagnostic challenges that affect prognostication of the condition. In this review, the authors discuss the controversies surrounding the diagnosis of BE, particularly in Asia...

Endosonography guided fine needle aspiration (EUS-FNA) is a safe and sensitive, minimally invasive method for evaluating patients with a solid lesion of the mediastinum suspected by computed tomography (CT) scanning. Here, we report the case where a diagnosis of a pericardial gastrointestinal stromal tumour (GIST) was established using EUS-FNA. This article is protected by copyright. All rights reserved.

A 85 yo female with severe dilatative cardiomiopathy underwent to gastroscopy for anemia (Hb 6.4 g/dl) and melaena, founding a bleeding submucosal gastric mass of 15 mm in size (Fig 1a). We performed a temporary hemostasis with epinephrine and Argon Plasma Coagulation and the contrast-enhncement CT-scan showed rapid wash in of the mass, as in presence of rich vascularization (Fig 1b).

BACKGROUND AND AIM: To assess the visibility of colorectal lesions using blue laser imaging (BLI)-bright and linked-color imaging (LCI) with an eye-tracking system. METHODS: Eleven endoscopists evaluated 90 images of 30 colorectal lesions. The lesions were randomly selected. Three images of each lesion comprised white light imaging (WLI), BLI-bright, and LCI in the same position. Participants gazed at the images, and their eye movements were tracked by the eye tracker...

OBJECTIVES: The pooling of the liquid in esophageal lumen can worsen the field of vision and cause liquid reflux to the mouth, which leads to aspiration pneumonia, in esophageal endoscopic submucosal dissection (ESD). We developed a continuously liquid-sucking catheter attachment for the endoscope (CLCA), which has multiple tiny holes and can suck the liquid without causing mucosal injury. Thus, we aimed to reveal the efficacy of CLCA in esophageal ESD. METHODS: This was a single-blinded, randomized controlled trial involving patients with superficial esophageal cancer...

OBJECTIVES: The Japan narrow-band imaging (NBI) Expert Team (JNET) classification is a recently proposed NBI magnifying endoscopy-based classification system for colorectal tumors. Although the usefulness of this system has been reported by JNET experts, its objective validity remains unclear. We tested its validity and usefulness for the diagnosis of colorectal polyps by including colonoscopy experts and non-experts as test participants. METHODS: Forty NBI images of polyps with various JNET types were shown to 22 doctors (11 experts and 11 non-gastrointestinal [GI] trainees) who had not examined the patients...

Although endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has potential risks such as pancreatitis, internal bleeding, and perforation, hepatic portal vein gas (HPVG) has never been reported. Here, we presented a case with HPVG after EUS-FNA. Unlike most HPVG related to bowel ischemia which usually needs surgical intervention with high mortality rate, our case was self-limited after conservative treatment. The 84-year-old man who has chronic hepatitis B related liver cirrhosis with esophageal and gastric varices presented with significant body weight loss for four months...

Endoscopic ultrasound (EUS)-guided needle-based confocal laser endomicroscopy (nCLE) is a new technique, which enables a real-time in vivo histopathology evaluation during EUS. Recently, nCLE used in the assessment of pancreatic cysts 1 2 . Solid pseudopapillary neoplasm (SPN) is rare, accounting for 1-2% of all pancreatic tumors 3 . We herein report the first case that shows a typical nCLE image of SPN. This article is protected by copyright. All rights reserved.

A 50-year-old asymptomatic man presented for screening esophagogastroduodenoscopy. Esophagogastroduodenoscopy showed a 10-mm semipedunculated type of submucosal tumor (SMT)-like protrusion with slight depression on top in the second portion of the duodenum (Fig. 1a). Narrow-band imaging showed irregular vessels in the depression (Fig. 2a), from which endoscopic biopsy showed adenocarcinoma. This article is protected by copyright. All rights reserved.

Helmut Neumann, Raf Bisschops
Over the past few years, we have been continuously learning about the progress of artificial intelligence (AI) systems and their involvement in many facets of our daily life. Autonomous vehicles, computerized border control, and specific search engines such as Google RankBrain, which provide more relevant search results for users, are already in daily use, thereby changing our life by accelerating procedures and making them more effective. With its continuous evolution, it was only a matter of time until AI was adopted for medical procedures, such as luminal gastrointestinal endoscopy...

BACKGROUND AND AIM: The aim of this randomised trial was to evaluate the performance of self-training vs. didactic training, to increase the diagnostic accuracy of diminutive/small colonic polyp histological prediction by trainees. METHODS: Sixteen trainees reviewed 78 videos (48 iSCAN-OE and 30 NBI) of diminutive/small polyps in a pre-training assessment. Trainees were randomised to receive computer-based self-learning (n=8) or didactic training (n=8) using identical teaching materials and videos...
