Endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography (EDGE) and endoscopic ultrasound-directed transenteric endoscopic retrograde cholangiopancreatography (EDEE) are innovative endoscopic techniques developed to overcome the challenges of biliary access in patients with surgically altered gastrointestinal anatomy. EDGE facilitates the creation of a gastro-gastric anastomosis, enabling endoscopic access to the excluded stomach and subsequent duodenum for endoscopic retrograde cholangiopancreatography (ERCP) procedures. Similarly, EDEE involves creating a gastro-jejunal anastomosis, allowing endoscopic access to the jejunum and hepaticojejunostomy for ERCP.

Background: Vitamin D plays a crucial role in immune modulation, gut barrier integrity, and inflammation regulation, making it highly relevant in inflammatory bowel disease (IBD). IBD patients often exhibit vitamin D deficiency, which has been linked to increased disease activity, impaired mucosal healing, and a higher risk of complications, including infections and osteoporosis.

Methods: This review examines the biological functions of vitamin D in maintaining intestinal homeostasis, particularly in the context of IBD.

Pancreatic cystic lesions (PCLs) are increasingly identified via computerized tomography (CT) and magnetic resonance (MR), with a prevalence of 2-45%. Distinguishing mucinous PCLs (M-PCLs), which include intraductal papillary mucinous neoplasms (IPMNs) and mucinous cystic neoplasms (MCNs) that can progress to pancreatic ductal adenocarcinoma, from non-mucinous PCLs (NM-PCLs) is essential. Carcinoembryonic antigen (CEA) remains widely used but often demonstrates limited sensitivity and specificity.

Introduction: Non-anesthesiologist-administered propofol (NAAP) sedation for outpatient endoscopy has proven to be safe. However, implementing NAAP in Western countries faces challenges, and propofol-based sedation is still largely administered by anesthetists. For low-risk patients, anesthesiologist-administered propofol (AAP) could represent an avoidable waste of healthcare resources.

Portal hypertension (PH) is a complication of advanced liver diseases, including cirrhosis and hepatocellular carcinoma, often leading to unfavorable outcomes. Endo-hepatology, particularly endoscopic ultrasound (EUS) has revolutionized the assessment of PH. Notably, EUS-guided portal pressure gradient (EUS-PPG) enables measurement of portal and hepatic venous pressures, offering diagnostic precision for both cirrhotic and non-cirrhotic forms of PH, including porto-sinusoidal vascular disorder (PSVD).

Anastomotic strictures are a common complication following esophagogastric surgery, with prevalence varying depending on the type of surgery and anatomical site. These strictures can lead to debilitating symptoms such as dysphagia, pain, and malabsorption, significantly impacting patients' quality of life. Endoscopic treatment of anastomotic strictures has established a role as the first-line strategy in this setting instead of revision surgery, offering benefits in terms of lower morbidity.

Article Synopsis
  • Lesion size (≥40mm) is a significant factor for recurrence after endoscopic mucosal resection, and post-resection margin thermal ablation (MTA) seems to reduce this risk.
  • A study analyzed outcomes across three phases from 2009 to 2023, revealing a notable decrease in recurrence rates after implementing standardized MTA, from 13.5% to 2.1%.
  • MTA effectively equalizes recurrence rates across all polyp sizes (20-39mm, 40-59mm, ≥60mm) when used, suggesting it could be an important strategy for managing larger colorectal polyps.

Background:  Lower gastrointestinal bleeding (LGIB) is a common condition linked to increased morbidity, healthcare costs, and mortality. Currently, no prospectively validated prognostic model exists to predict mortality in patients with LGIB. Our aim was to develop and validate a risk score that could accurately predict in-hospital mortality of patients admitted for LGIB.

Barrett's esophagus (BE) represents a pre-cancerous condition that is characterized by the metaplastic conversion of the squamous esophageal epithelium to a columnar intestinal-like phenotype. BE is the consequence of chronic reflux disease and has a potential progression burden to esophageal adenocarcinoma (EAC). The pathogenesis of BE and EAC has been extensively studied but not completely understood, and it is based on two main hypotheses: "transdifferentiation" and "transcommitment".

Nonlifting large nonpedunculated colorectal polyps (NL-LNPCPs) account for 15% of LNPCPs and are effectively managed by endoscopic mucosal resection (EMR) with adjunctive cold-forceps avulsion with adjuvant snare-tip soft coagulation (CAST). Recurrence rates >10% at surveillance colonoscopy are however a significant limitation. We aimed to compare the outcomes of CAST plus margin thermal ablation (MTA) versus CAST alone for NL-LNPCPs.

Endoscopic ultrasound (EUS)-guided interventions have revolutionized the management of malignant biliary obstruction (MBO) and gastric outlet obstruction (GOO), providing minimally invasive alternatives with improved outcomes. These procedures have significantly reduced the need for high-risk surgical interventions or percutaneous alternatives and have provided effective palliative care for patients with advanced gastrointestinal and bilio-pancreatic malignancies. EUS-guided biliary drainage (EUS-BD) techniques, including hepaticogastrostomy (EUS-HGS), choledochoduodenostomy (EUS-CDS), and antegrade stenting (EUS-AS), offer high technical and clinical success rates, with a good safety profile particularly when Endoscopic Retrograde Cholangiopancreatography (ERCP) is not feasible.

Article Synopsis
  • Killian-Jamieson diverticulum (KJD) is a rare esophageal condition typically treated with surgery, but a new method called KJ-POEM (per-oral endoscopic myotomy) offers a minimally invasive alternative.
  • An international study reviewing 13 patients who underwent KJ-POEM found that both clinical and technical success rates were 100%, with significant symptom improvement post-procedure.
  • The procedure demonstrated excellent safety, with no adverse events reported, a short hospital stay of about 1 day, and no recurrence of symptoms during the follow-up period of nearly 9.5 months.

Background And Aims: The efficacy of colorectal endoscopic mucosal resection (EMR) is limited by recurrence and the necessity for conservative surveillance. Margin thermal ablation (MTA) after EMR has reduced the incidence of recurrence at the first surveillance colonoscopy at 6 months (SC1). Whether this effect is durable to second surveillance colonoscopy (SC2) is unknown.
