Ultrasound elastography can be used to differentiate MPE from benign diseases by evaluating pleural stiffness. This study aimed to investigate whether ultrasonic elastography-guided pleural biopsy (UEPB) offers diagnostic accuracy superior to that of TUSPB for pleural effusions.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n In this multicentre, randomised trial (\n ClinicalTrials.gov<\/jats:ext-link>\n :\n NCT05781659<\/jats:ext-link>\n ), patients with pleural effusion of unknown origin were enrolled and randomised (1:1) to undergo either UEPB or TUSPB. The primary outcome measured was the sensitivity of UEPB in diagnosing MPE; the secondary outcomes were the diagnostic rate of the two methods in patients with different pleural thicknesses and the safety of UEPB.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n In total, 232 patients with pleural effusion were enrolled, 228 of whom were included in the analysis. The sensitivity for detecting MPE was significantly greater in the UEPB group than in the TUSPB group (85.00% (51\/60)\n versus<\/jats:italic>\n 63.16% (36\/57); p=0.007). Patients in the UEPB group had a significantly greater diagnostic yield than those in the TUSPB group (87.83% (101\/115)\n versus<\/jats:italic>\n 76.99% (87\/113); p=0.032). For patients with MPE and a pleural thickness \u22645\u2005mm who did not have pleural nodules, UEPB had a significantly greater sensitivity than TUSPB (80.49% (33\/41)\n versus<\/jats:italic>\n 50.00% (15\/30); p=0.007). The rates of procedure-related complications were similar between the UEPB and TUSPB groups (5.22%\n versus<\/jats:italic>\n 7.96%; p=0.403).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n UEPB was superior to TUSPB in the diagnosis of MPE with a similar safety profile.<\/jats:p>\n
