RODRIGUEZ-WULFF, Erika et al. Pancreatic endoscopic ultrasound guided aspiration our experience and assistance for matching cytopathologist. Gen [online]. 2012, vol.66, n.3, pp.161-165. ISSN 0016-3503.

The fine needle aspiration cytology guided by endoscopic ultrasound is a method of definitive diagnosis of pancreatic diseases. Our objective was to review the indications, technique and results of the pancreatic punctures and calculate the index of agreement between the preliminary diagnoses in the room and the final cytohistologic report. Method: Were included the total of pancreatic punctures performed from April 2009-2011. The indications, the puncture site, needle used, number of passes, preliminary results and final results cytohistologic parameters and estimated concordance index, were emptied in a table. Results: We included 179 punctures, mean age of patients 59.39 years, 55% male, 45% female, whose indications were tumor in 67%, cystic lesion 12%, inflammatory disease 14%, papillary hyperplasia7%. The approach was duodenal in 52%, gastric 48%, 22G needle was used in 83%, 25G at 17%. There was no attendance by 6%. Preliminary result was reported in 95% of patients, we calculated the Kappa index of 0.791 obtaining a value to be reported a good strength of agreement. Conclusion: The puncture is an excellent tool for minimally invasive form of cytohistology of the pancreas that has a good range of overlap between the initial and final diagnosis if cytopathologist is in the room.
