Objective: To determine the sensitivity and specificity of endoscopic ultrasound (EUS) guided fine needle aspiration cytology (FNAC) in the evaluation of pancreatic masses.
Study Design: Analytical study.
Place And Duration Of Study: Department of Pathology, Shaukat Khanum Cancer Hospital and Research Centre, from January 2006 to June 2011.
Methodology: Patients of either gender aged above 18 years who underwent EUS guided FNAC of pancreatic masses detected on abdominal CT, were included in the study. Biphasic abdominal CT scans were carried out for all the patients, followed by EUS guided FNAC. All material aspirated for cytologic evaluation was assessed for sample adequacy on-site, followed by formal examination for diagnostic purposes.
Results: The mean age of patients tested was 58.94 ± 12.84 years with age ranging from 23 to 78 years. Regarding gender 23/42 (54.76%) patients were male and 19/42 (45.24%) were female. Out of 42 cases, 27 (64%) cases were diagnosed as adenocarcinoma, 4 (9.5%) as benign, 4 (9.5%) as mucinous cystic neoplasm, 2 (4.7%) as chronic pancreatitis, 2 (4.7%) as non-diagnostic, 2 (4.7%) as atypical cells seen and 1 (2.38%) as non-Hodgkin's lymphoma. The results were in full concordance with radiologic findings.
Conclusion: EUS guided FNA is an excellent procedure for evaluation of pancreatic masses. The overall sensitivity of this procedure is 89% and the specificity is 67%.

Background And Aim: Although long self-expandable metal stent (SEMS) with a sufficient intragastric portion is typically preferred for endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), this design can complicate endoscopic re-intervention for recurrent biliary obstruction (RBO). We evaluated the efficacy and safety of endoscopic re-intervention for RBO through the stent after EUS-HGS using a novel partially covered SEMS with an anchoring flange.
Methods: The partially covered SEMS was designed with a intrahepatic uncovered portion measuring 1.
Endoscopic-Ultrasound-Guided Radiofrequency Ablation for Pancreatic Tumors.

Endoscopic ultrasound (EUS)-guided radiofrequency ablation (RFA) is a promising minimally invasive technique for the treatment of pancreatic lesions. This review first focuses on the technical aspects in EUS-RFA: the procedure typically employs EUS probes with integrated radiofrequency electrodes, enabling accurate targeting and ablation of pancreatic lesions. Different types of RFA devices, monopolar and bipolar energy delivery systems, are discussed, along with considerations for optimal ablation, including energy settings, procedure time, and pre- and post-procedural management.

Endoscopic management of benign pancreaticobiliary disorders encompasses a range of procedures designed to address complications in gallstone disease, choledocholithiasis, and pancreatic disorders. Acute cholecystitis is typically treated with cholecystectomy or percutaneous drainage (PT-GBD), but for high-risk or future surgical candidates, alternative decompression methods, such as endoscopic transpapillary gallbladder drainage (ETP-GBD), and endoscopic ultrasound (EUS)-guided gallbladder drainage (EUS-GBD), are effective. PT-GBD is associated with significant discomfort as well as variable adverse event rates.

View Article and Find Full Text PDFBackground And Aims: Pancreatic fluid collections (PFCs), including walled-off necrosis (WON), are significant complications of acute pancreatitis, and their management often involves drainage, although the optimal type of stent for this purpose remains uncertain. This meta-analysis aimed to compare metal versus plastic stents for endoscopic ultrasound (EUS)-guided drainage of PFCs.
Methods: We searched PubMed, Embase, and Cochrane Library for randomized controlled trials (RCTs) comparing metal with plastic stents for drainage of PFCs.
