BACKGROUND: CT-guided percutaneous lung nodule biopsy (CLNB) is a critical diagnostic tool for pulmonary lesions, yet traditional methods are limited by operator-dependent variability and higher complication risks. The dual-laser beam design of the laser positioning (LP) device, utilizing real-time trajectory correction, holds potential to improve puncture accuracy and reduce human error, but its clinical value in CLNB remains to be systematically validated.
BACKGROUND: The purpose of this study was to retrospectively assess the advanced puncture efficacy and clinical safety of the LP device during CLNB.
METHODS: A total of 115 patients (61±12 [SD]years; 83 women) were included in this study. All patients were allocated into two groups: one group underwent CLNB without an LP device, while the other group used an LP device during the procedure. The efficacy of the procedures was assessed based on the success rate, the adjustments number and the puncture time. Additionally, safety evaluations focused on complications associated with the percutaneous surgery.
RESULTS: The success rate of the first puncture in the LP group was significantly higher than in the CLNB group [88.70%(55/62) vs. 52.80%(28/53), p < 0.001]. The puncture time was significantly lower in the LP group (9.71±4.20 vs. 18.21±6.53 min, p < 0.001). When analyzing the skin-to-lesion distance, categorized into two ranges of 20-60 mm and > 60 mm, the LP group consistently required less time for the procedure (9.66±5.20 vs. 16.86±5.16 min, p < 0.001), (9.93±3.97 vs. 19.31±7.39 min, p < 0.001). Furthermore, the incidence of complications in the LP group was significantly lower than in the CLNB group [6.45% (4/62) vs. 50.94% (27/53), p < 0.001].
CONCLUSIONS: The LP device improved the puncture accuracy of CLNB, shortened the operation time, and reduced the incidence of complications.
