Abstract:
Objective To explore the feasibility,safety and effectiveness of ultrasound-guided biopsy of pancreatic lesions with exophytic and backward growth morphology.Methods Fifty-three patients with pancreatic lesions with exophytic and backward growth morphology who underwent ultrasound-guided biopsy were retrospectively collected.Conventional ultrasonic manifestations of lesions were observed,and the technical success rate,complication rate,repeat puncture rate,as well as the sensitivity,specificity and accuracy of biopsy were recorded.Results Totally 61 lesions were detected,with the maximum diameter of 1.4-7.3 cm and the median maximum diameter of 2.7 cm,located in pancreatic uncinate process(26/61,42.62％),head(12/61,19.67％),neck(13/61,21.31％)and body(10/61,42.62％),respectively,mainly presented as hypoechogenic(61/61,100％)and borderless(60/61,98.36％)masses tending to invade blood vessels(51/61,83.61％)and pancreatic ducts(40/61,65.57％).The technical success rate,complication rate and repeat puncture rate of ultrasound-guided biopsy was 100％(61/61),1.89％(1/53)and 21.31％(13/61),respectively,and the sensitivity,specificity and accuracy of biopsy diagnosis was 75.00％(45/60),100％(1/1)and 75.41％(46/61),respectively.Conclusion Ultrasound-guided biopsy was safe and feasible for pancreatic lesions with exophytic and backward growth morphology,but its diagnostic efficacy should be improved.
