ESD is an established technique for the endoscopic therapy of dysplastic and early cancerous lesions throughout the GI tract. The procedure requires both a sophisticated knowledge for lesion characterization and high-level endoscopic skills. As a result, the learning curve is very steep and in Japan it takes years to gain proficiency under the traditional Master-Apprentice teaching model. At present, due to multiple limitations, this training model is not applicable in the U.S. Nevertheless, a unique, multi-pronged, stepwise approach has emerged as a viable pathway to train U...

Peroral endoscopic myotomy (POEM) is a novel technique developed in Japan; it is used to treat esophageal achalasia and esophageal motility disorders. This technique has been rapidly accepted and widely disseminated throughout our clinical practice because of its low invasiveness, technical novelty, and high efficacy. Since the advent of POEM, there have been no clinical guidelines that clearly indicated its standard of care, and these guidelines have been anticipated both nationally and internationally by clinicians who engage in POEM practice...

Takeshi Ogura, Nobu Nishioka, Kazuhide Higuchi
Electrohydraulic lithotripsy (EHL) under endoscopic retrograde cholangiopancreatography (ERCP) guidance for pancreatic duct stone (PDS) has been established as a treatment option [1-3]. However, pancreatic duct strictures or PDS in the pancreatic head can cause difficulties with pancreatoscope insertion and PDS visualization that would render EHL challenging. Under such circumstances, endoscopic ultrasound (EUS)-guided access is one option for pancreatic duct drainage [4]. The present report describes technical tips for transluminal antegrade EHL for PDS...

Esophageal endoscopic submucosal dissection (ESD) for large lesions has a risk of post-ESD stricture.1,2 Local triamcinolone injection3 or filling4 are reportedly useful to reduce the incidence of post-ESD stricture, but strictures requiring balloon dilation can occur3,4 Although oral prednisolone may be more effective than local triamcinolone,5 it raises concerns regarding adverse effects. We considered that a combination of triamcinolone injection and filling can enhance the stricture-prevention effect. Therefore, we assessed this method for two large defects...

BACKGROUND AND AIMS: Mucosal lifting and its persistence are critical for maintaining the operational space and preventing perforation in endoscopic operation. Although numerous agents have been investigated, optimization is still required for improving their clinical performance. In this study, we proposed a novel concept of thermo-responsive aerification and tissue vacuolization for submucosal injection. METHODS: The lifting performance and operational condition were firstly evaluated in porcine stomachs in vitro and rabbits in vivo...

We read with great interest the article by Dr. De Pastena M, et al. 1 This retrospective study identified that preoperative biliary drain does not increase major complications and mortality rates after pancreatoduodenectomy, but it is associated with higher surgical site infection rates. Herein, we would like to raise the following comments. This article is protected by copyright. All rights reserved.

Hideki Kobara, Hirohito Mori, Tsutomu Masaki
Endoscopic mucosal resection sometimes fails to obtain curative resection of small-sized gastric neoplasms due to slippage of the snaring device and insufficient surgical margins; thus, endoscopic submucosal dissection (ESD) is required.1-3 However, ESD is technically difficult, and the ESD knife is expensive (more than 215 USD). Moreover, conventional ESD for small-sized neoplasms does not sometimes meet the criteria of health insurance. This article is protected by copyright. All rights reserved.

Tadahisa Inoue, Kiyoaki Ito, Masashi Yoneda
Endoscopic ultrasound (EUS)-guided antegrade stenting combined with hepaticogastrostomy is useful in patients with malignant biliary stricture complicated by duodenal obstruction. Biliary radiofrequency ablation (RFA) can improve stent patency. However, to the best of our knowledge, there are no reports of biliary RFA performed under EUS-guided approach. Here, we report a successful case of antegrade RFA and stenting through an EUS-guided hepaticogastrostomy. This article is protected by copyright. All rights reserved...

We read with interest the manuscript by Choi et al. (1), which describes EUS-guided ethanol-lipiodol ablation (EUS-ELA) of 40 neuroendocrine tumors (NETs) in 33 patients. The inclusion criteria were a diameter <2, low suitability for surgery, or refusal of surgery. By reading the article it is not clear the volume of the EL solution that was injected to obtain ablation of NETs. This article is protected by copyright. All rights reserved.

During this session, 3 European and 4 Japanese endoscopists gave presentations on 3 ERCP and 4 EUS topics (Table 1, Figure 1).It has been 50 years since ERCP was developed and it is now the standard of care for endotherapy for pancreatobiliary diseases. However, we still have two unsolved problems in ERCP, biliary cannulation and post-ERCP pancreatitis, which was discussed by Tringali and Arvanitakis. According to the ESGE guideline[2], the guidewire-assisted technique is recommended for biliary cannulation rather than the contrast-assisted technique to obtain biliary access and to reduce post-ERCP pancreatitis (PEP)...

BACKGROUND AND AIMS: Different post-polypectomy guidelines underscore the need for high quality baseline colonoscopy before appropriate surveillance recommendations can be made. Standards for colonoscopy practice have been advocated by gastrointestinal societies. Our aims were to define standards for the procedural practice of colonoscopy in this particular setting of surveillance and to generate a colonoscopy procedural quality checklist that could be implemented in clinical practice...

Familial Adenomatous Polyposis (FAP) is a genetic condition characterized by extensive adenoma development throughout the gastrointestinal (GI) tract. GI neoplasias have been removed via endoscopic submucosal dissection in patients with FAP after total colectomy [1]. However, treatment modalities for biliary adenomas as a complication of FAP are not well described. We describe a case of a 70 year old male with attenuated FAP treated initially with total colon resection with ileorectal anastomosis. This article is protected by copyright...

A 68-year-old female patient with 21-year history of entire ulcerative colitis was admitted for abdominal pain and hematochezia. The patient was successfully treated with azathiopurine and infliximab five years previously. However, this combination therapy was discontinued due to cryptococcus meningitis. Since then, she had been under monotherapy of oral mesalazine (4,000 mg/day). Colonoscopy on admission revealed active inflammation in the rectum and sigmoid colon. She dislike 5-ASA enema.

A 58-year-old man underwent endoscopic submucosal dissection (ESD) for large superficial esophageal squamous cell neoplasm. The length of whole-circumferential mucosal defect was 6 cm (25-31 cm). Curative resection was achieved and histopathology revealed high-grade intraepithelial neoplasia (m2). To prevent post-operative stricture, a self-help inflatable balloon was placed immediately after ESD. The study was conducted under the ethics committee approval from the PLA General Hospital (S2017-116-01). This article is protected by copyright...

Pancreatic cystic lesions (PCLs) are increasingly diagnosed with the advent of cross-sectional imaging and its incidence was as high as 13.7% on MRI in asymptomatic individuals, which increased with age or obesity [1]. Most of those asymptomatic PCLs are not malignant at the time of diagnosis but require surveillance, which can pose physical and psychological burden to those individuals under surveillance as well as the burden of medical costs. Although several guidelines for management of PCLs have been published, they are not necessarily evidence-based...

The Blue Rubber Bleb Nevus Syndrome (BRBNS) is a rare congenital disease, characterized by the presence of multiple venous malformations in the skin, gastrointestinal tract and other organs. Small bowel (SB) complications are intussusception, volvulation and small bowel bleeding (SBB)1 . Surgery may be limited by the multiplicity of lesions, morbidity, and the need of intraoperative endoscopy2 . Although close follow-up is mandatory because of the risk of recurrence, endoscopy may be an alternative This article is protected by copyright...

OBJECTIVES: The rendezvous postoperative endoscopic retrograde cholangiopancreatography (ERCP) technique has been introduced as a modification of the single-session rendezvous intraoperative ERCP procedure in the management of concurrent common bile duct stones during cholecystectomy. There are no reports on the impact of this modified technique on post-ERCP morbidity. The objective of this study was to study and compare the rendezvous techniques in terms of procedure-associated morbidities, such as post-ERCP pancreatitis and postoperative infections...

OBJECTIVES: The implications of the preoperative biliary drain on morbidity and mortality after pancreatoduodenectomy are still controversial. The study aims to assess the impact of the preoperative biliary drain on postoperative outcome and to define the optimal serum bilirubin cut-off to recommend biliary drainage in patients undergoing pancreatoduodenectomy. METHODS: All consecutive pancreatoduodenectomies, performed at Verona Hospital from 2005 to 2016, were retrospectively analyzed...

OBJECTIVES: Endoscopic papillary larger balloon dilation (EPLBD) without endoscopic sphincterotomy (EST) may facilitate extraction of large bile duct stones through achieving adequate dilation of the ampulla. However, contrary to favorable long-term outcomes after endoscopic papillary balloon dilation (EPBD), that of EPLBD without EST has been little investigated. Therefore, we conducted a current study to evaluate short- and long-term outcomes of EPLBD without EST and EPBD after removal of large bile duct stones (LBDS; ≥ 10 mm)...

Intra-diverticular papilla is considered as a difficult anatomical orientation for biliary cannulation. 1 2 3 To our knowledge, this is the first report to show the usefulness of biopsy forceps for cannulation not only to expose the ampulla in the case of an intra-diverticular papilla but also for axis alignment.An 85-year-old woman underwent endoscopic retrograde cholangiopancreatography for a common bile duct (CBD) stone. A duodenoscope (TJF TYPE 260V; Olympus Medical Systems, Tokyo, Japan) was inserted into Vater's papilla...
