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.

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.

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...

Although endoscopic submucosal dissection (ESD) is gradually becoming a first-line treatment for superficial esophageal neoplasms (SENs), strictures occur in almost 100% of cases after circumferential ESD. A standard method has not been established. Thus, we propose a novel self-help inflatable balloon to prevent stricture. The new balloon was used by the patients themselves at home (4-5 times a day, each time lasted about 15-20 minutes), and would be removed when the defects were almost healed. From January 2018 to September 2018, 8 patients who received circumferential ESD for SENs and underwent a novel self-help inflatable balloon to prevent stricture were enrolled...

Most patients with colonic diverticular hemorrhage (CDH) achieve spontaneous hemostasis. Nonetheless, endoscopic hemostasis is required in some cases. Despite its safety and convenience, endoscopic clipping has a reported rebleeding rate of 37.0% at 1-year, which is significantly higher than 11.5% for endoscopic band ligation (EBL).2 Therefore, the effectiveness of EBL has been evaluated; however, a small number of delayed perforations have been reported.

OBJECTIVE: This study aimed to compare the effectiveness of endoscopic injection sclerotherapy (EIS) and endoscopic variceal ligation (EVL) in managing esophageal varices (EVs) according to the diameter of para-esophageal varices (PEVs) on computed tomography (CT). METHODS: In this retrospective study, EIS and EVL were compared as initial and palliative treatments for patients with EVs who were treated at our hospital from 2012 to 2017. The PEV diameter was measured using CT, and EVL treatment was chosen for patients with PEVs >4 mm...

A neonate who had undergone surgery for intestinal obstruction induced by inguinal hernia incarceration at 15 days after birth was referred to our hospital with fever and gray stool. Blood tests revealed increases in hepatobiliary enzymes and inflammatory reactions. MRI revealed choledocholithiasis and gallbladder stones, suggesting cholangitis due to choledocholithiasis (Figures.1A,1B). Since invasive treatment should be avoided because the patient was a neonate, fasting and antibiotic administration was selected...

BACKGROUND AND AIM: An antireflux metal stent (ARMS) for nonresectable distal malignant biliary obstruction may prevent recurrent biliary obstruction (RBO) due to the duodenobiliary reflux and prolong time to RBO (TRBO). The superiority of the ARMS over conventional covered self-expandable metal stents (SEMSs) has not been fully examined. METHODS: We conducted a multicenter randomized controlled trial to examine whether TRBO of an ARMS with a funnel-shaped valve was longer than that of a covered SEMS in SEMS-naïve patients...

A 64-year-old female presented with a slightly elevated 50-mm lesion in the cecum, which was spread into the appendiceal orifice. The lesion was endoscopically diagnosed to be a sessile serrated adenoma/polyp without dysplasia. Endoscopic submucosal dissection (ESD) was performed using a therapeutic colonoscope (PCF-Q260JI, Olympus) and a small-caliber-tip transparent hood (ST-hood DH-29CR, Fujifilm). First, hyaluronic acid and glycerol solution were submucosally injected into the normal mucosa of the appendiceal canal...

Toshio Kuwai, Sauid Ishaq
Flexible endoscopic septum division (FESD) is emerging as an effective minimally invasive treatment for Zenker's diverticulum (ZD). Overall prevalence of ZD is rare. Therefore, ZD was historically treated by surgery, and there are no reports of FESD for ZD in Japan to date. In this video, we would like to show first two cases of ZD successfully treated with FESD.

Kiyoyuki Kobayashi, Hideki Kobara, Tsutomu Masaki
Walled-off pancreatic necrosis (WON) is a severe complication of acute necrotizing pancreatitis with pancreatic fluid collection. Endoscopic ultrasound (EUS)-guided drainage has been proposed as first-line treatment for WON. A newly developed lumen-apposing metal stent (LAMS) was recently introduced for WON drainage. Some studies have shown efficacy of the LAMS over the double pigtail plastic stent (PS), which is recognized as the conventional drainage option. This article is protected by copyright.
