Abstract:
Objective:To investigate the effectiveness and safety of the coaxial needle technique in percutaneous liver biopsy for patients with coagulation function abnormalities.Methods:Clinical data of 210 patients who underwent percutaneous liver biopsy using the coaxial needle technique under ultrasound guidance from December 2018 to May 2021 in 3 centers were collected. A retrospective analysis was conducted to compare the puncture success rate, number of samples obtained, pathology qualification rate, intraoperative and postoperative bleeding rates between the group with coagulation function abnormalities and the group with normal coagulation function.Results:After propensity score matching, there were 105 patients in each group, with a puncture success rate of 100% in both groups. The pathology qualification rate was 100% for all samples.Intraoperative bleeding occurred in 78 cases (74.3%, 78/105) in the coagulation function abnormalities group and in 64 cases (61.0%, 64/105) in the normal coagulation function group, with a statistically significant difference between the two groups ( P=0.006). Postoperative bleeding occurred in 3 cases (2.9%, 3/105) in the coagulation function abnormalities group and in 0 case in the normal coagulation function group, with no statistically significant difference between the two groups ( P=0.081). Conclusions:The use of the coaxial needle technique for percutaneous liver biopsy in patients with coagulation function abnormalities not only allows for obtaining an adequate tissue sample but also demonstrates good safety.
