INTRODUCTION: Pancreatic Neuroendocrine Neoplasms (PanNENs) are characterized by a highly heterogeneous clinical and biological behavior, making their diagnosis challenging. PanNENs diagnostic work-up mainly relies on biochemical markers, pathological examination, and imaging evaluation. The latter including radiological imaging (i.e. computed tomography [CT] and magnetic resonance imaging [MRI]), functional imaging (i.e. 68Gallium [68 Ga]Ga-DOTA-peptide PET/CT and Fluorine-18 fluorodeoxyglucose [18F]FDG PET/CT), and endoscopic ultrasound (EUS) with its associated procedures...

Gastrointestinal (GI) endoscope is one of the instruments used extensively in the diagnosis and treatment of digestive tract disorders. China is confronted with a great demand for endoscopists working in grassroots healthcare facilities. Furthermore, endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasonography (EUS), and endoscopic submucosal dissection (ESD) are becoming the prevailing methods of endoscopic treatment of digestive diseases. Therefore, there is a growing demand for senior endoscopists...

BACKGROUND AND AIMS: Most pancreatic insulinomas can be treated by minimally invasive modalities. The aim of this meta-analysis was to assess the clinical outcomes of endoscopic ultrasound (EUS)-guided ablation and minimally invasive surgery (MIS) in the treatment of pancreatic insulinoma. MATERIALS AND METHODS: Online databases were searched for relevant studies. The primary aim was to compare the rates of adverse events (AEs) and the secondary aims were to compare the clinical and technical success rates, length of hospital stays, and symptom recurrence rates between EUS and MIS approaches...

Pancreatic tuberculosis (TB) is a rare condition that can be challenging to distinguish from other pancreatic neoplasms. We present the case of a 48-year-old Indian male who complained of persistent vague epigastric pain for two months. Other physicians saw him and treated him like a dyspeptic case. He gave a history of daily alcohol consumption. Routine investigations, including amylase and lipase levels, were within normal limits. However, an abdominal ultrasound revealed a cystic lesion in the body of the pancreas, prompting further investigation...

AIM: Comprehensive genomic profiling (CGP) test for solid tumors is now increasingly utilized in clinical practice, especially in pancreatobiliary cancer, and specimens obtained by endoscopic ultrasound-guided tissue acquisition (EUS-TA) are often submitted for tissue-based CGP test. In this study, we evaluated the feasibility of EUS-TA using a 22-gauge Franseen needle for the CGP test. METHODS: Consecutive patients with solid tumors who underwent EUS-TA using a 22-gauge Franseen needle, and whose tissue samples were pre-checked for suitability for CGP test, were included in this single-center, retrospective analysis...

Background and study aims Endoscopic ultrasound-directed transgastric intervention (EDGI) is a technique that creates an anastomosis between the gastric pouch or jejunum to the excluded stomach in Roux-en-Y gastric bypass (RYGB) anatomy to allow access to the pancreaticobiliary system. Thus far, management of anastomosis closure at the time of lumen-apposing metal stent (LAMS) removal has varied widely. This study aimed to assess the efficacy of primary closure at the time of LAMS removal using a through-the-scope (TTS) tack-based suture system...

BACKGROUND AND AIM: The microsurface structure reflects the degree of damage to the glands, which is related to the invasion depth of early gastric cancer. To evaluate the diagnostic value of quantitative microsurface structure analysis for estimating the invasion depth of early gastric cancer. METHODS: White-light imaging and narrow-band imaging (NBI) endoscopy were used to visualize the lesions of the included patients. The area ratio and depth-predicting score (DPS) of each patient were calculated; meanwhile, each lesion was examined by endoscopic ultrasonography (EUS)...

Chronic liver disease has emerged as a significant global concern, with primary hepatocellular carcinoma (HCC) representing a critical consequence of this disease. However, early detection of HCC remains challenging in clinical practice. Recently, there has been a growing interest in applying endoscopic ultrasound (EUS) as a diagnostic tool for gastrointestinal diseases. Nevertheless, using EUS to diagnose and treat HCC is uncommon. In this review we described the diagnostic and therapeutic applications of EUS in primary HCC and evaluated its clinical significance...

Aim The study aims to determine the incidence of malignancy at presentation and subsequent risk of malignancy (at 12 months follow-up) in a cohort of patients with double duct sign (DDS) on cross-sectional imaging but no visible stigmata of jaundice. The study also correlates malignancy with liver enzyme dysfunction and estimates the resource burden incurred during the investigation of these patients. Methods A search for the key term "double duct sign" was undertaken in the radiological database of a tertiary hepatopancreatobiliary (HPB) centre between March 2017 and March 2022...

BACKGROUND AND AIMS: This pilot study aimed to evaluate safety and tissue sampling from subepithelial lesions (SEL) in the upper gastrointestinal tract with a novel electric motor driven endoscopic ultrasonography (EUS)-guided 17-gauge (G) size core needle biopsy (CNB) instrument. METHODS: An investigator-led prospective open label, performance and safety control study, including seven patients (female n  = 4, median 71 y, range 28-75) with a determined SEL (median size 30 mm, range 17-150 mm) in the upper digestive tract (stomach n  = 6, duodenum n  = 1) were eligible and later followed up 14 days after index procedure...

BACKGROUNDS AND AIMS: EUS-guided vascular intervention has expanded the horizons of diagnostic as well as therapeutic interventions for vascular pathology. EUS-guided embolization is a commonly performed technique for the treatment of gastric varices. However, there is a lack of data on the standardization of the technique. Here, we review the techniques and difficulties encountered during EUS-guided embolization of varices and pseudoaneurysms. METHODS: This article and accompanying video describe the EUS-guided embolization techniques for various vascular lesions...

Colloid pulmonary adenocarcinoma represents a seldom encountered neoplasm in clinical practice. The diagnostic process for this rare neoplasm is complicated by its infrequency and the limited understanding of its specific molecular imaging characteristics. We report a 65-year-old male who was diagnosed with pulmonary colloid mucinous cystadenocarcinoma. Fluorine 18-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) was conducted for initial evaluation. The scan showed mild 18F-FDG expression at the primary tumor site, and several non-18F-FDG-avid mediastinal and paraesophageal lymph nodes exhibited suspicious morphologic features...

Gastric duplication cysts (GDCs) in adults are exceedingly rare, with only a few documented cases in medical literature. The spectrum of clinical presentations varies widely, ranging from asymptomatic to severe symptoms such as hematemesis, vomiting or abdominal pain. Among the less common complications associated with GDCs, segmental portal hypertension is a notable rarity. We present a compelling case report of a patient exhibiting signs of segmental portal hypertension, where ultrasound and echo-endoscopy revealed a sizable gastric duplication cyst as the underlying etiology...

PURPOSE: To assess the diagnostic value of abbreviated protocol (AP) MRI to detect the degeneration signs in branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs) in patients undergoing a routine MRI follow-up. METHODS: This dual-center retrospective study include patients with BD-IPMN diagnosed on initial comprehensive protocol (CP) MRI who underwent routine MRI follow-up. CP included axial and coronal T2-weighted images (T2WI), axial T1-weighted images (T1WI) before and after contrast administration, 3D MR cholangiopancreatography (MRCP) and diffusion-weighted images (DWI)...

A 61-year-old man present to us with continued abdominal pain without abdominal tenderness for 1 month. Blood testing showed elevated biliary enzymes and inflammation. Contrast-enhanced computed tomography (CT) revealed thickening of the transverse colon with relatively strong enhancement but no bile duct dilatation. Colonoscopy revealed localized edema and granular mucosa in the transverse colon. Fluoroscopic endoscopy exhibited the absence of haustra. Multiple biopsies were performed, but differentiation between mild inflammation and mucosa-associated lymphoid tissue (MALT) lymphoma was inconclusive...

BACKGROUND AND AIM: Cystic dilatation of the gastric glands within the mucosal layer is the hallmark of the rare condition known as gastritis cystica profunda (GCP). Although it has been proved that GCP is the precursor lesion for early gastric cancer (EGC), the management strategy of GCP-related EGC is not well established.The purpose of this research was to determine if ESD is effective and safe for GCP-related EGC. METHODS: Patients with EGC who had ESD at Beijing Friendship Hospital between January 2015 and May 2023 were retrospectively included...

An 82-year-old man had been treated for lung adenocarcinoma and hepatocellular carcinoma (HCC). Contrast-enhanced computed tomography examination showed swelling of the left adrenal gland, suggesting metastasis of lung adenocarcinoma, HCC, or primary adrenal tumor. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed for the pathological diagnosis, and adrenal metastasis of HCC was diagnosed. No notable complications due to EUS-FNA were found. There have been reports of adrenal metastasis due to various cancers, but there are few reports that can confirm the diagnosis of adrenal metastasis of HCC using EUS-FNA...
