摘要

目的:网膜活检通常采用手术方法进行。在临床实践中,增厚的网膜可作为超声引导下经皮穿刺活检的有用靶点。我们研究的目的是确定超声引导下经皮大网膜增厚活检的诊断价值和安全性。此外,我们的目的是研究活检结果与穿刺液细胞学的相关性。方法:回顾性研究纳入49例患者(女性33例,男性16例;平均年龄64±13.9 [SD]岁),于2014年至2022年在单一机构接受超声引导下的大网膜活检,其中US作为大网膜活检指导的一线方式。对每位患者进行活检后的临床随访。我们比较活检和穿刺液细胞学结果的结果。结果:共纳入49例患者。49例患者中有46例(93.8%)被诊断出活检。恶性肿瘤36例(73.4%),慢性结核性炎症5例(10.2%),慢性腹膜感染2例(4.1%)。3例核心活检结果为良性,报告为ig4相关炎性假瘤、硬纤维瘤病和脂肪坏死-异物反应。36例恶性肿瘤中,17例(47.2%)为卵巢癌。没有重大并发症。在25例接受穿刺液取样的患者中,有21例(%84)细胞学结果(恶性或良性细胞学)与大网膜活检结果一致。在16/25(64%)的患者中,腹水细胞学评价有利于恶性肿瘤。结论:超声引导下经皮大网膜活检是一种经济、安全、有效、诊断准确率高的方法。穿刺液细胞学结果对大网膜增厚患者非常敏感。

Diagnostic Accuracy and Safety of Ultrasound Guided Omental Biopsy: Single Center Experience
Aim: Omental biopsy has conventionally been performed using a surgical approach. The thickened omentum can serve as a useful target for ultrasonography guided percutaneous biopsy, in clinical practice. The objective of our study was to determine the diagnostic value and safety of ultrasound guided percutaneous biopsy of omental thickening. Additionally, we aim to investigate the correlation of biopsy results with the paracentesis fluid cytology. Methods: This retrospective study included 49 patients (33 women and 16 men; mean age, 64 ± 13.9 [SD] years) who underwent ultrasound guided omental biopsy between 2014 and 2022 at a single institution at which US served as the first-line modality for omental biopsy guidance. Post-biopsy clinical follow-up were reviewed for each patient. We compare the outcomes of biopsy and paracentesis fluid cytology results. Results: Total 49 patients were included in our study. US-guided biopsy was diagnostic in 46/49 (93.8%) of patients. There were total 36 (73.4%) malignant cases, 5 (10.2%) chronic inflammation suggestive of tuberculosis, while 2 (4.1%) were chronic peritoneal infection. In 3 patients, the result of core biopsy was benign and reported as Ig4-related inflammatory pseudotumor, desmoid fibromatosis and fat necrosis-foreign body reaction. Out of 36 malignant cases, majority 17 (47.2%) had ovarian cancer. There were no major complications. In 21 of 25 patients (%84) who underwent paracentesis fluid sampling, cytology results (malign or bening cytology) were found to be consistent with omental biopsy results. The ascitic cytological evaluation was favourable for malignancy in 16/25 (64%) patients. Conclusions: Ultrasound-guided percutaneous biopsy of omentum is less expensive, safe and effective method with a high diagnostic accuracy. Paracentesis fluid cytology results are highly sensitive in patients with omental thickening.
