Background and Aims: The application of endoscopic suturing has revolutionized defect closures. Conventional over-the-scope necessitates removal the scope, placement device, reinsertion. A single channel, sequence, through-the-scope device been developed to improve this process. This study aims describe efficacy, feasibility, safety a for gastrointestinal closure. Methods: was retrospective multicenter involving 9 centers consecutive adult patients who underwent using X-Tack Endoscopic HeliX...
Abstract Background A benign esophageal stricture (BES) is an narrowing that causes dysphagia in the absence of inflammation. First-line treatment for BES bougie or balloon dilation. Esophageal stent placement a option refractory strictures (RBES) but comes with significant complication risks. Aims We aim to assess complications following RBES and whether there are differences migration rates depending on length, width, presence clip suture fixation. Methods This retrospective cohort study...
Abstract Background Variety of needle tips and suction techniques have been trialled to optimize diagnostic yield in EUS-FNB for comprehensive histopathological analysis with some studies suggesting improved performance franseen tip Aims Obtain an objective comparison between 2 different 22g franseen-tip needles; novel flexible sheath (FS) traditional stiff (SS) Methods Sample patients presenting outpatient elective were selected. Underwent using both a SS FS FNB during same procedure. Equal...
Abstract Background Gastric conduit dysfunction is a common post-operative complication of esophagectomy. Established treatments include pyloric botox, dilatation, pyloromyotomy, and most definitively, surgical revision. We present case gastric that was refractory to management. Aims To due helical stenosis; bring awareness this rare condition novel application endoscopic myotomy. Methods Case report literature review. Results: Report A 69-year-old male underwent Ivor Lewis esophagectomy for...
Abstract Background Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is an emerging treatment for acute cholecystitis in patients who are poor surgical candidates. There a lack of EUS-GBD data the Canadian setting, which may differ from its global counterparts pattern healthcare availability, aging population, and use conscious sedation. Aims To describe outcomes following setting. Methods The case series included undergoing by interventional gastrointestinal endoscopist tertiary...
Abstract Background Gastrointestinal stromal tumors (GISTs) are rare mesenchymal found throughout the gastrointestinal tract, with esophageal GISTs being particularly uncommon. Surgical resection is standard treatment option, though it associated significant morbidity. Submucosal Tunneling Endoscopic Resection (STER) a minimally invasive technique for per-oral subepithelial tumor removal preservation of surrounding esophagus and no need thoracoscopy or mediastinoscopy. Herein, we report...
Abstract Background Gastric outlet obstruction (GOO) refers to the clinical syndrome of epigastric pain and postprandial vomiting due mechanical in distal stomach or proximal duodenum. Management is undertaken alleviate symptoms with aim maintaining nutritional status improving quality life. Endoscopic gastroduodenal stenting surgical gastroenterostomy (SGE) are two established methods management GOO. Enteral associated stent malfunction such as migration often requiring reintervention; SGE...
As knowledge regarding the pathophysiology of obesity and mechanisms action for bariatric procedures has evolved, opportunities have been created to develop new interventions that more directly address these mechanisms. One potential target is gastric emptying. This a critical step in digestion found be rapid after prolonged exposure high-fat diet both animal human studies, with emptying also being common young people some studies.1Pajot G. Camilleri M.

Non-alcoholic fatty liver disease (NAFLD) is common with widely ranging severity. Non-invasive risk scores for stratification are recommended but misclassify a significant proportion of patients. In situations where non-invasive do not provide guidance, referral typically made to Hepatologist transient elastography or biopsy. Serum ferritin elevated in many patients NAFLD related dysmetabolic and inflammatory hyperferritinemia. Ferritin available part standard workup chronic disease.To...

Abstract Background With the rates of non-alcoholic fatty liver disease (NAFLD) on rise, necessity identifying patients at risk cirrhosis and its complications is becoming ever more important. Liver biopsy remains gold standard for assessing fibrosis, although costs, risks, availability prohibit widespread use at-risk patients. Fibroscan has proven to be a non-invasive accurate way this modality often limited in primary care setting. The Fibrosis-4 (FIB-4) Non-Alcoholic Fatty Disease...
