Comparison of laser-guided technology and conventional manual percutaneous lung biopsy: a single-center retrospective study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Percutaneous lung biopsy (PLB) is currently widely utilized in the diagnosis and treatment of lung tumors, owing to its advantages of minimal trauma, high detection rate, and precise localization. However, traditional computed tomography (CT)-guided freehand PLB procedures often involve multiple puncture adjustments and a relatively high incidence of complications. The aim of this study is to investigate whether laser-guided technology can effectively reduce the operative time and incidence of complications. Methods: This study included 141 patients who underwent CT-guided PLB at the First Affiliated Hospital of Soochow University between January 2022 and January 2024. These patients were divided into two groups based on the use of laser-guided technology during the procedure: the laser-guided group (47 patients) and the manual group (94 patients). Clinical data from all patients were collected. Information such as the success rate of biopsy procedures and the incidence of complications was analyzed and compared. Results: The procedure time in the laser-guided group was shorter than that in the manual group (P=0.008). In the laser-guided group, the number of adjustments needed to reach the tumor during the positioning step was less than the manual group (P=0.001). In the laser-guided group, the number of CT scans performed before reaching the tumor was smaller than in the manual group (P=0.01). The distance from the first puncture to the lung tumor in the laser-guided group was closer than that in the manual group (P=0.049). The laser-guided group had a smaller angular deviation from the target at the first puncture than the manual group (P=0.004). Conclusions: Laser-guided technology has the advantages of shorter operation time and less adjustment of biopsy needles. However, laser-guided technology does not reduce the complication rate of biopsy surgery or the length of hospital stay after surgery and there is no statistical difference in the accuracy of pathological diagnoses obtained by the two methods.
