ABSTRACT
BackgroundEndoscopic Ultrasound (EUS) is a well-established mode of intervention for tissue acquisition in solid organs with rapid on-site evaluation (ROSE). In the Covid-19 era, the implementation of infection control mechanisms has led to modified hybrid techniques to get high diagnostic yield for tissue sampling. Combination of Covid-19 SOPs and tissue acquisition method outline this hybrid technique to get a high diagnostic Yield. We share our initial experience of EUS cases performed with this approach without ROSE.MethodsAll 125 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.ResultsAmong these cases, 85 were male, mean age of 56 years (range 22–90), Mean duration of procedure 28 minutes mean (10–90 min). 91 cases for organs targeted for malignant pathology include pancreas 53, liver 03, lymph nodes 22, subepithelial lesions 10, mediastinal lesions 15, common-bile duct/gall bladder 07, gastric and retroperitoneal 01 case, 13 cases had a multi-targeted biopsy for the additional staging of disease. The number of ‘passes’ with the needle was average 02 with single pass 20, two pass 60, three passes 20, multitarget single pass in 25. Needle size (Franseen design) used for procedures was 22G in 115 cases and 25G in 10. Common tissue diagnoses include pancreatic adenocarcinoma 38, neuroendocrine tumours 06, tuberculosis 07, gastrointestinal stromal tumours 03, leiomyoma 05, lymphoma 06, metastatic renal cell carcinoma 05, squamous cell carcinoma 05, cholangiocarcinoma/gall bladder adenocarcinoma 13, Sarcoma 03, solid pseudopapillary epithelial neoplasm of pancreas (SPEN) 03 and one case for Schwannoma, breast metastasis, accessory spleen, ectopic pancreas, sarcoidosis There were no immediate or early complications in all cases.ConclusionsHybrid EUS in Covid 19 Era has emerged as a useful/cost-effective and safe approach to get tissue yield without the need for ROSE.
