1: ESGE recommends the combination of endoscopic ultrasound-guided tissue acquisition (EUS-TA) and endoscopic retrograde cholangiopancreatography (ERCP)-based tissue acquisition as the preferred diagnostic approach for tissue acquisition in patients with jaundice and distal extrahepatic biliary stricture in the absence of a pancreatic mass. 2: ESGE suggests that brushing cytology should be completed along with fluoroscopy-guided biopsies, wherever technically feasible, in patients with perihilar biliary strictures. 3: ESGE suggests EUS-TA for perihilar strictures when ERCP-based modalities yield insufficient results, provided that curative resection is not feasible and/or when cross-sectional imaging has shown accessible extraluminal disease.

- - Neuroendocrine neoplasms (NENs) are diverse tumors from neuroendocrine cells, with about 30% causing hormone-related syndromes that can significantly impact patient health beyond the tumor size itself.
- - A 49-year-old male patient with an ileal NEN exhibited concurrent VIP and serotonin release, leading to a severe diarrhea syndrome after receiving peptide-radio-receptor therapy, despite ongoing medical treatments.
- - As traditional treatment options were no longer effective, an off-label use of racecadotril helped manage the patient's condition, allowing him to leave the ICU after five days of treatment.
: Anastomotic insufficiencies (AI) and perforations of the upper gastrointestinal tract (uGIT) result in high morbidity and mortality. Endoscopic stent placement and endoluminal vacuum therapy (EVT) have been established as surgical revision treatment options. The Eso-Sponge is the only licensed EVT system with limitations in treating small defects (<10 mm).

- Colonoscopy effectively evaluates active ulcerative colitis (aUC) but is limited to the mucosal surface, whereas endoscopic ultrasound (EUS) combined with contrast-enhanced ultrasound (dCEUS) measures bowel wall thickness and blood flow, providing insight into inflammation levels.
- In a study involving 45 aUC patients treated with adalimumab (ADA) or infliximab (IFX), significant changes in bowel wall thickness and vascularity were observed as early as 2 weeks, particularly in those responding to treatment.
- The findings suggest that dCEUS can predict therapy success early on, making it a valuable tool for monitoring aUC treatment outcomes.
Circumferential scanning in endoscopic imaging is crucial across various disciplines, and optical coherence tomography (OCT) is often the preferred choice due to its high-speed, high-resolution, and micron-scale imaging capabilities. Moreover, real-time and high-speed 3D endoscopy is a pivotal technology for medical screening and precise surgical guidance, among other applications. However, challenges such as image jitter and non-uniform rotational distortion (NURD) are persistent obstacles that hinder real-time visualization during high-speed OCT procedures.
