Abstract

Background

Ultrasound-guided biopsy (UGB) is a diagnostic procedure that is usually performed by radiologists; however, its use by internists has been poorly studied. This study evaluated the diagnostic yield, accuracy, and safety of UGB for focal lesions with a high suspicion of malignancy in an Internal Medicine Department.

Methods

We retrospectively analyzed 255 UGB in 248 patients between 2021 and 2024. Solid organ biopsies were performed to evaluate diagnostic yield, complications, and factors associated with success.

Results

The overall diagnostic yield was 84% with an accuracy of 83% for malignancy and 89% for benignity. The biopsies predominantly comprised of hepatic, pulmonary, and lymph node specimens. Major complications occurred infrequently (3%). Factors such as sample size and accumulated experience improved the results.

Conclusions

UGBs performed by internists for focal lesions suspected of malignancy are safe and effective. Its implementation can reduce diagnostic time and improve patient care.

超声引导下内科局灶性病变活检的产率。

背景：超声引导活检（UGB）是一种通常由放射科医生执行的诊断程序；然而，内科医生对其使用的研究却很少。本研究评估了UGB对内科高度怀疑为恶性肿瘤的局灶性病变的诊断率、准确性和安全性。方法：我们回顾性分析了2021 - 2024年间248例患者的255例UGB。进行实体器官活检以评估诊断率、并发症和与成功相关的因素。结果：总体诊断率为84%，其中恶性肿瘤的准确率为83%，良性肿瘤的准确率为89%。活检主要包括肝、肺和淋巴结标本。主要并发症很少发生（3%）。样本量和经验积累等因素改善了结果。结论：内科医师对怀疑为恶性灶性病变实施UGBs是安全有效的。它的实施可以缩短诊断时间并改善患者护理。
