About
Dr. Harry Aslanian is a Professor of Medicine in the Department of Digestive Diseases at Yale School of Medicine. He specializes as an advanced endoscopist focusing on pancreas and biliary disorders, including pancreas cysts, masses, chronic pancreatitis, bile duct stones and strictures, as well as the diagnosis and treatment of Barrett's esophagus, early esophageal and gastric cancer, and various gastrointestinal neoplasms. His expertise encompasses performing endoscopic ultrasound (EUS), EUS-FNA, FNB, celiac neurolysis, pseudocyst drainage, ERCP, enteral stenting, endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), POEM, and advanced imaging techniques. Dr. Aslanian serves as the Director of Endoscopic Ultrasound and the Yale Advanced Endoscopy Fellowship, contributing significantly to clinical care, research, and training in advanced endoscopic procedures.

articleSenior authorPerforming endoscopic retrograde cholangiopancreatography (ERCP) procedures is associated with musculoskeletal (MSK) pain and injury in physicians. Previous studies have explored MSK symptoms among those who assist with endoscopy in general; this study aims to describe the prevalence and predictors of MSK pain and injury specifically among nurses and technicians who assist with ERCP. An anonymous electronic survey was distributed to nurses and technicians involved in ERCP procedures at institutions affiliated with the American Society of Gastrointestinal Endoscopy. Out of 150 respondents, 92.7% reported experiencing at least one MSK symptom, with 61.5% attributing these symptoms to assisting with ERCP. Additionally, 36% reported a diagnosis of MSK conditions, including carpal tunnel syndrome (13.33%), lumbar radiculopathy (7.33%), and De Quervain's tenosynovitis (6%). Only 20% of participants received prior training on ergonomics in endoscopy; 80.7% of the participants expressed interest in injury prevention training. Most of those surveyed report an MSK pain symptom, with more than half attributing this pain to assisting with ERCP procedures. Future studies into specific risk factors for MSK pain and injury in nurses and technicians are advised and can inform policies and procedures for preventing injury.

articleOBJECTIVE: An accurate fine-needle aspiration (FNA) diagnosis of adrenal lesions may be challenging. This study was to investigate roles of imaging guidance, rapid on-site evaluation (ROSE) and additional tissue sampling in FNA diagnosis of adrenal lesions. METHODS: Adrenal FNA cases were retrieved from pathology archive. Patients' demographics, lesion size and location, imaging guidance methods, cytologic diagnoses and histopathologic diagnoses were reviewed and analysed. RESULTS: The study cohort included 72 cases of left (86%) and right (14%) adrenal lesions. Endoscopic ultrasound (EUS) and computed tomography (CT) were used in 47 (65%) and 25 (35%) cases, respectively. Left adrenal lesions were sampled mostly by EUS-FNA (73%), whereas right adrenal lesions by CT-guided FNA (80%). There were no differences between the EUS-FNA and CT-FNA groups in terms of non-diagnostic rate and cytologic diagnostic categories. The non-diagnostic rate and cytologic diagnostic categories were the same between ROSE and non-ROSE groups. In a subset of 18 cases with concurrent core tissue biopsy, a definite diagnosis was rendered in all biopsy cases including three cases with a non-diagnostic or indeterminate cytology diagnosis. CONCLUSION: Our study demonstrates that FNA has great efficacy for evaluation of adrenal lesions, either via EUS or CT guidance. Incorporation of ROSE evaluation into FNA procedure does not directly affect the performance of FNA biopsy but may help direct additional tissue sampling to salvage the cases with a non-diagnostic or indeterminate cytology diagnosis, increasing diagnostic yield.
