Endoscopic ultrasound (EUS) was introduced in the early 1980s in an attempt to improve sonographic imaging of the pancreas. Its uses have been expanded to include examination of the upper and lower gastrointestinal tracts, hepatobiliary and portal systems,and the anal sphincter; diagnosis and staging of esophageal, gastric,and pancreaticobiliary tumors; and evaluation of mediastinal nodes in lung cancer. Although EUS has its limitations and is greatly dependent on operator skill, it has wide-ranging interventional and therapeutic applications that can be expected to increase in the future with technologic advances and greater educational opportunities for physicians.

Endoscopic ultrasound-guided biopsy of healthy pig pancreas - Towards the histological diagnosis of chronic pancreatitis.
Rev Esp Enferm Dig
September 2024
Gastroenterology, Hospital Clínico Universitario de Santiago.
Background: diagnosis of early chronic pancreatitis (CP) is a challenge due to the lack of accurate methods. The ability of endoscopic ultrasound (EUS) guided biopsy to obtain pancreatic core tissue samples in patients with minimal changes of CP and its potential use for the histological diagnosis of early CP are unknown. The aim of the study was to evaluate the ability of different EUS-guided biopsy core needles to obtain histological samples of healthy pig pancreas.

Objective: To investigate the role of endoscopic ultrasonography (EUS) in the diagnosis and treatment of upper gastrointestinal bleeding of unknown origin in liver cirrhosis, focusing on patients with recurrent treatment of esophageal and gastric varices who failed to identify the bleeding site under direct endoscopy.
Background: Esophagogastric variceal bleeding is one of the severe complications of decompensated liver cirrhosis, and serial endoscopic therapy can improve the long-term quality of life of patients. Most acute bleeding can be detected under direct endoscopy with thrombus or active bleeding, but there are still some patients with recurrent bleeding after repeated treatments, and it is difficult to find the bleeding site, especially in gastric variceal bleeding.
Gastric polyps are not created equal: Know your enemy.

Gastric polyps are commonly detected during upper gastrointestinal endoscopy. They are most often benign and rarely become malignant. Nevertheless, adequate knowledge, diagnostic modalities, and management strategies should be the endoscopist's readily available "weapons" to defeat the potentially malignant "enemies".

Department of Gastrointestinal Surgery, Hepato-Pancreatico-Biliary and Liver Transplantation (Rajesh Gupta), Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India.
Background: Fatty changes in the pancreas are common, whereas total pancreatic lipomatosis (PL) is rare. Commonly associated with various components of metabolic syndrome and metabolic-associated steatotic liver disease, total PL can have various etiologies and can manifest with severe pancreatic exocrine insufficiency.
Method: We retrospectively analysed the clinical profile and management outcomes of 8 patients (mean age: 37.
Randomized comparison of precut papillotomy and endosonography guided rendezvous procedure for difficult biliary access in Malignant distal biliary obstruction.
Endoscopy
January 2025
Institute of Gastrosciences, Sir HN Reliance Foundation Hospital and Research Centre, Mumbai, India.
Background And Aims: Difficult biliary cannulation (DBC) is a marker for prolonged procedure time and increased adverse event rate (AER) during endoscopic retrograde cholangiopancreatography (ERCP). We previously showed that EUS-guided rendezvous procedure (EUS-RV) had a higher single session success rate than precut papillotomy (PcP) in DBC patients. The present randomized study aims at comparing the technical success and AER between the two approaches.
