Resumen
SOTO-SOLIS, Rodrigo et al. Rapid on-site cytologic evaluation during endoscopic ultrasound-guided biopsies of pancreatic solid lesions. Cir. cir. [online]. 2020, vol.88, n.4, pp.435-440. Epub 08-Nov-2021. ISSN 2444-054X. https://doi.org/10.24875/ciru.20001572.
Background:
Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is safe and effective for the diagnosis of pancreatic adenocarcinoma. Although rapid on-site evaluation (ROSE) can improve tissue collection and increase diagnostic yield, its utility has been recently questioned.
Objective:
Determine the diagnostic efficacy of EUS-FNB with ROSE of pancreatic masses in a new echoendoscopy unit.
Method:
Cross-sectional and comparative study of patients who underwent EUS-FNB of pancreatic masses between January and July 2017. Patient demographics, ultrasonographic details and pathology reports were examined.
Results:
A total of 23 procedures were analyzed. Median age was 59 years (range: 46-77). The group with ROSE had 13 patients (56.5%) and the group without ROSE 10 (43.5%). The final pathology report showed enough and adequate sample in 100% of the group with ROSE (13/13 vs. 5/10; p = 0.007). Diagnosis of malignancy was established in 84.6% of the biopsies (11/13 vs. 2/10; p = 0.003) in the group with ROSE.
Conclusions:
ROSE is useful to improve the diagnostic efficacy of EUS-FNB of pancreatic masses, especially in new EUS centers or in centers with a low diagnostic yield.
