Abstract:
ObjectiveTo evaluate the diagnostic value of ultrasound or CT guided percutaneous Trucut needle biopsy on the diagnosis of pancreatic tumors.Methods One hundred and twenty-four patients clinically diagnosed as pancreatic cancer without pathological diagnosis underwent percutaneous pancreatic biopsy by using Trucut needle under ultrasound or CT guidance.ResultsOne hundred and nine procedures of ultrasound-guided biopsy and 15 procedures of CT-guided biopsy were performed,and one patient received 2.3times of punctures.Tissue samples were obtained in all 124 patients,the diagnostic accuracy was 95.2％,among them 115 were adenocarcinoma,5 were cystadenoma,2 were metastasis cancer,1 was cancer of unknown origin and 1 was normal.The sensitivity,specificity,and accuracy were 99.2％ 100％,and 99.2％,respectively.Transient serum amylase increase was observed in 3 patients; 5 patients' abdominal pain aggravated,but all recovered with conservative management.One patient was found to have tumor seeding on the spot of insertion after 34 days.No other major complications occurred.ConclusionsUltrasound or CTguided percutaneous pancreatic 16 ～ 18G Trucut needle biopsy is a safe and simple procedure with excellent diagnostic value for pancreatic cancer.
