GOMEZ, Martín Alonso; RUIZ, Oscar  e  LUQUEZ MENDIOLA, Adán. Hybrid technique versus standard technique for endoscopic ultrasound guided fine needle aspiration of solid pancreatic lesions. Rev Col Gastroenterol [online]. 2019, vol.34, n.4, pp.337-344. ISSN 0120-9957.

Endoscopic ultrasound (EUS) is widely used to evaluate pancreatobiliary diseases, especially pancreatic masses. EUS has a good ability to detect pancreatic masses, but it is not sufficient for differential diagnoses of various types of lesions. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is the diagnostic method of choice for pancreatic masses, but its accuracy is affected by various puncture methods.

Materials and methods:

Our objective was to compare the diagnostic yield of examinations of solid lesions in the pancreas by the standard suction technique (ST) with the yield of the hybrid technique (HT) using a prospective, single blind, randomized, controlled design. Patients diagnosed with solid pancreatic lesions who underwent EUS-FNA from May 2014 to June 2016 were included.


We included 65 patients, 34 of whom (52.3%) were assigned to EUS-FNA with HT, and 31 of whom (47.7%) were assigned to EUS-FNA with TS. We found that the relative frequency that HT successfully obtained an adequate amount of tissue for the cytological diagnosis was 85.2% while ST’s relative frequency of success was 71%. The odds ratio was 2.35 (95% CI; 1.2-4.7) in favor of HT.


This study suggests that the TH is superior to ST for diagnosis of solid pancreatic lesions. Since implementation of this technique does not increase costs and is very simple, we suggest that it become the technique of choice for EUS-FNA.
