Several reports have demonstrated the efficacy of temporary, fully covered, metallic stents (FCMSs) for resolving refractory pancreatic ductal strictures caused by chronic pancreatitis1,2 . However, to our knowledge, no reports of FCMS placement for malignant pancreatic strictures have been published. Here, we placed an FCMS in a patient with unresectable recurrent pancreatic cancer, with concurrent malignant pancreatic stricture and refractory intraperitoneal abscess caused by a pancreatic fistula.

Endoscopic submucosal dissection (ESD) for circumferential esophageal cancer inevitably causes a post-ESD stricture. Although oral prednisolone1 , local triamcinolone injection2 and balloon dilation3 (including a self-help inflatable baloon4 ) can prevent their formation, standardized method has not been established5 . We report a case in which scope bougienage was effective for a post-ESD stricture in circumferential esophageal cancer.

OBJECTIVE: Discomfort associated with the gag reflex during transoral endoscopy can be quite troublesome. To overcome this problem during esophagogastroduodenoscopy (EGD), we recently developed a novel mouthpiece. The aim of this study was to compare the acceptance and tolerability of transoral EGD with the conventional and new mouthpieces in unsedated patients and analyze the effects of the new mouthpiece. METHODS: This study consisted of two phases of cephalometric and EGD examinations to analyze the effects of the new mouthpiece...

OBJECTIVES: Same-visit colonoscopy and esophagogastroduodenoscopy (EGD) have become common. Recent studies showed conflicting results regarding the performance, safety, and efficacy of different sequences. We conducted this meta-analysis to determine the most favorable performance and discomfort between an EGD followed by colonoscopy (E-C) and colonoscopy followed by EGD (C-E). METHODS: The authors searched the databases of MEDLINE and EMBASE. The outcomes of interest were the performance (including cecal intubation time, adenoma detection rate, and polyp detection rate), discomfort score (patients and endoscopists; Likert scale), and sedation uses...

BACKGROUND AND STUDY AIMS: Acute Gastro-intestinal bleeding carries poor outcomes unless prompt endoscopic hemostasis is achieved. Mortality in these patients remains significant. Hemospray is a novel intervention that creates a mechanical barrier over bleeding sites. We report the largest dataset of patient outcomes after treatment with Hemospray from an international multicentre registry. PATIENTS AND METHODS: Prospective data (Jan 2016 - May 2018) from 12 centres across Europe were collected...

OBJECTIVE: In chronic pancreatitis (CP) patients, diagnosis of small pancreatic lesions by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is challenging. Thus, the aim of our study was to investigate whether CP influences the diagnostic ability of EUS-FNA for pancreatic lesions ≤10 mm. METHODS: One hundred and seventeen patients who underwent EUS-FNA for pancreatic lesions ≤10 mm in size were enrolled. Patients were classified into two groups based on features of CP observed by EUS (EUS-CP features) in accordance with the Rosemont classification...

Esophageal achalasia is a rare chronic debilitating disorder characterized by incomplete lower esophageal sphincter (LES) relaxation and abnormal peristalsis due to myenteric plexus degeneration. Although complex interactions among immunity, viruses and inheritance have been proposed, its causes remain unknown. MicroRNAs (miRs) play crucial roles in regulation of gene expression during pathophysiological processes. Certain viruses representing herpes simplex virus (HSV) encode miRs derived from their own genomes...
