Diagnostic value of different puncture needles in endoscopic ultrasonography guided aspiration for pancreatic solid masses / 中华胰腺病杂志

ABSTRACT

Objective To compare the diagnostic value of two different types of puncture needles guided by endoscopic ultrasonography for pancreatic solid masses.Methods The clinical data of 176 pancreatic solid tumor patients who received endoscopic fine needle aspiration (EUS-FNA) in Shanghai Changhai Hospital from January 2018 to December 2018 was retrospectively analyzed.The acquired specimens were analyzed by cytology and histology.The patients were divided into 25G acupuncture needle group (25G group,63 cases) and 22G acupuncture needle group (22G group,113 cases) according to the type of acupuncture needle.The satisfaction score of specimen,the positive rate of puncture and diagnostic accuracy of malignant masses were compared between the two groups.Results The satisfaction of specimen in 25G group (44.6 ± 18.8) was higher than 22G group (20.5 ± 18.1),and the differences were statistically significant (P =0.047).The positive rates of puncture were 79.3％ and 85.8％,respectively,and the differences were not statistically significant (P =0.267).Thirty nine of 176 patients underwent surgical resection.Thirty three cases of malignant were diagnosed pathologically.The accuracy of 25G and 22G group was 81.3％ and 86.9％,respectively,and the differences were not statistically significant.Conclusions The accuracy and positive rate of 25G and 22G needle in the diagnosis of pancreatic solid masses are comparable,but compared with 25G needle,22G needle can obtain more tissue specimen.
