Trans-organ versus trans-mesenteric computed tomography-guided percutaneous fine-needle aspiration biopsy of pancreatic masses: Feasibility and safety

Covid 19 is an acute respiratory disease caused by a novel type of Coronavirus (SARS-CoV-2) that was first detected in Wuhan, Hubei Province of China. Its most common symptoms are fever, cough, and weakness; and in the early stages, there may not be findings on chest computed tomography. In pulmonary involvement, peripheral ground-glass areas, a cobblestone appearance, consolidated areas, and interlobular septal thickening, which are usually prominent in the lower lobes may be seen in thorax computed tomography. Consolidation, solid nodules, halo sign, inverted halo sign, vascular enlargement, subpleural line, air bronchograms, and bronchiectasis are other less common findings. In our case, we aimed to present our 69 years old female patient with bilateral nodular densities on thoracic CT and transthoracic fine-needle aspiration biopsy result was reported as lesions compatible with interstitial fibrosis due to Covid-19 inflammation.

Needle Aspiration Biopsy

Background and Objectives. Recently, a 21G Menghini-type needle for EUS-guided fine-needle aspiration biopsy (EUS-FNAB) has been developed. The stylet of the EUS Sonopsy CY™ remains inside the needle during aspiration. Therefore, it is expected to obtain higher-quality histological core specimens without crushing the material or blood contamination. The aim of this study is to evaluate the feasibility and diagnostic accuracy of EUS-FNAB of solid pancreatic masses with this new biopsy needle. Methods. A total of 30 patients with solid pancreatic masses who underwent EUS-FNAB with two different types of needles, EUS Sonopsy™ and ProCore™, were included in a prospective, randomized, controlled, crossover study. All the pancreatic masses were punctured with the two needles and were randomized regarding the order of the needle to be used. The primary outcome was to compare the diagnostic accuracy and the rates of tissue acquisition of the two needles. Results. The tissue acquisition rate was not significantly different between the EUS Sonopsy CY™ needle and the ProCore™ needle (78.6% vs. 82.1%, P=1.00). The histological diagnostic accuracy was also similar between the two needles (73% vs. 80%, P=.63). There was also no difference regarding the accuracy of cytology alone and the combination of both histological and cytological assessments between the EUS Sonopsy CY™ needle and the ProCore™ needle (90% vs. 87%, P=1.00 and 90% vs. 90%, P=1.00, respectively). Conclusions. EUS Sonopsy CY™ is a reliable device for EUS-FNAB of solid pancreatic masses.
