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.

Department of Gastroenterology, Ruijin Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai 200025, China.
Background And Objectives: A majority of pancreatic malignancies are unresectable at the time of presentation and require EUS-guided fine-needle aspiration or fine-needle biopsy (EUS-FNA/FNB) for diagnosis. With the advent of precision therapy, there is an increasing need to use EUS-FNA/FNB sample for genetic analysis. Next-generation sequencing (NGS) is a preferred technology to detect genetic mutations with high sensitivity in small specimens.

Department of Gastroenterology, Beijing Friendship Hospital, Capital Medical University, National Clinical Research Center for Digestive Disease, Beijing, China.
Background And Objectives: Distal biliary strictures (DBSs) can be caused by various malignancies, making accurate and early diagnosis crucial. Histopathology is the gold standard for diagnosis, with several methods available for tissue sampling. This study evaluates the performance of EUS-guided fine-needle aspiration (EUS-FNA) cytologic smears and histopathology in diagnosing suspected malignant DBSs.

Department of Gastroenterology, Ponderas Academic Hospital, Bucharest, Romania.
Background: EUS-guided fine-needle biopsy is the procedure of choice for the diagnosis of pancreatic ductal adenocarcinoma (PDAC). Nevertheless, the samples obtained are small and require expertise in pathology, whereas the diagnosis is difficult in view of the scarcity of malignant cells and the important desmoplastic reaction of these tumors. With the help of artificial intelligence, the deep learning architectures produce a fast, accurate, and automated approach for PDAC image segmentation based on whole-slide imaging.
