IDDF2022-ABS-0160 Safety and Efficacy of Endoscopic Ultrasound Eus-G in Geriatric Population

Background Endoscopic Ultrasound EUS is now considered as the standard of care in the diagnosis of oncology patients to help plan management. Endoscopy in the elderly population is also important when they need tissue diagnosis to further treatment plans in suspected malignant pathology. We share our experience of EUS-G in the elderly population, which plays a pivotal role in their management. All samples were considered adequate by an expert pathologist to conclude a histological diagnosis. Methods All 40 cases who underwent EUS-guided biopsy from June 2020 till June 2022 were included. The Procedure was done in a negative pressure room with all SOPs as per institutional guidelines for patient and staff safety with a minimum number of persons during the procedure. Procedures were done in conscious sedation, and informed consent was obtained, and those patients who were on antiplatelet or anticoagulation agents were held as appropriate. All samples were collected using MOSE macroscopic onsite evaluation. Results Among these cases, 32 were male, mean age of 73 years (range 65–90), Mean duration of the procedure 27 minutes mean (10–71 min). 32 cases for organs targeted for malignant pathology include pancreas 17, lymph nodes 03, subepithelial lesions 01, mediastinal lesions 08, common-bile duct/gall bladder 05, and retroperitoneal 01 case, 05 cases had a multi-targeted biopsy for the additional staging of disease. The number of ‘passes’ with the needle was an average 2.4 with single pass 07, two pass 18, three passes 07, and multitarget single pass in 08. Needle size (Franseen design) used for procedures was 22G in 35 cases and 25G in 05. Common tissue diagnoses include pancreatic adenocarcinoma 15, tuberculosis 01, gastrointestinal stromal tumours 01, Benign 07, lymphoma 01, metastatic renal cell carcinoma 04, squamous cell carcinoma 03, cholangiocarcinoma/gall bladder adenocarcinoma 05, and Sarcoma 03. There were no immediate or early complications in all cases. Conclusions EUS-G is a safe and effective modality in evaluating and diagnosing a different variety of pathologies in elderly populations with high diagnostic yield.
