Supplementary value of abdominal ultrasound-guided percutaneous biopsy for endoscopic ultrasound-guided biopsy in diagnosing pancreatic tumors
Objective To observe the supplementary value of abdominal ultrasound-guided percutaneous biopsy for endoscopic ultrasound(EUS)-guided biopsy in diagnosing pancreatic tumors.Methods Data of 30 patients with pancreatic tumor who underwent abdominal ultrasound-guided percutaneous biopsy due to unsatisfactory diagnostic results of EUS-guided biopsy(tumor cells could not be seen in 20 cases,abnormal cells were visible but unable to be diagnosed in 10 cases)were retrospectively analyzed.The supplementary value of abdominal ultrasound guided-percutaneous biopsy was analyzed.Results Among 20 cases EUS-guided biopsy did not find tumor cells,abdominal ultrasound-guided biopsy clearly diagnosed pathological type of pancreatic tumor in 11 cases,found abnormal cells but could not diagnosed in 7 cases,but failed to detect tumor cells in 2 cases.Among 10 cases EUS-guided biopsy showed abnormal cells but could not diagnose,abdominal ultrasound-guided biopsy clearly diagnosed pathological type of pancreatic tumor in 9 cases,but atypical cells could be seen in 1 case.Conclusion Abdominal ultrasound-guided percutaneous biopsy had high supplementary value for EUS-guided biopsy of pancreatic tumors.
