Aims:

To present the evolution of endoscopic ultrasound (EUS) and the results of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in the study of solid tumors of the pancreas in Paraguay.

Methods:

Retrospective analysis from the data of the Centro Paraguayo de Ultrasonografia Endoscopica (CPEUS) of endoscopic ultrasound procedures carried out o patients > 18 years of age from 1 August 2014 through 31 August 2017.

Results:

EUS cases (n = 167) were caried out by a single endoscopist at 3 sites over the study period. Out of the total number of studies, 94 were diagnostic and 73 were with FNA. In 2014 15 studies were performed and in 2017 64. The first year 26,7% were done with FNA and 48,4% in the last year.

28 patient underewent one or two EUS wtih FNA for pancreatic tumor. Out of 33 puncture perforomed on pancreatic mass, 27 (81,81%) were positive for diagnosis. 4 patients needed a second puncture due to negative results. 3 of these achieved a diagnosis after a second puncture.

In total, 26 (92,83%) of 28 patients achieved a final histological diagnosis. Pancreas adenocarcinoma accounted for 64,28%, neuroendocrine tumors for 10,71%, metastatic tumors for 10,71% and one case of chronic pancreatitis and one single case of a probable solid pseudopapilary tumor.

Conclusions:

This is the first survey of EUS in Paraguay where it has recently been introduced (Since August 2014). We have seen an increase in the number of EUS studies over the years. In EUS-FNA, 81,8% were diagnostic whereas in 2015 only 75% were diagnostic. The greater number of studies carried out has impacted on the greater quality of the samples acquired. Even though there are a growing number of indications, the technique still requires more diffusion for a better development.
