EUS-guided fine-needle core liver biopsy sampling using a novel 19-gauge needle with modified 1-pass, 1 actuation wet suction technique - 21/06/18
Abstract |
Background and Aims |
EUS-guided fine-needle core biopsy sampling is a safe and effective technique for diagnosis of focal liver lesions. However, data are limited in its role in parenchymal disease. We evaluated the utility of EUS-guided parenchymal liver biopsy sampling with a modified 1-pass wet suction technique (EUS-modified liver biopsy sampling [EUS-MLB]) in patients with unexplained increase in liver-associated tests.
Methods |
We retrospectively evaluated the safety and efficacy of EUS-MLB in patients referred for EUS to evaluate for biliary obstruction and pancreatic disorders but with associated unexplained liver tests. EUS-MLB was performed during the same session after biliary obstruction was excluded.
Results |
One hundred sixty-five consecutive patients underwent EUS-MLB. The median age was 52 years (interquartile range [IQR], 42-65). Sixty-eight patients (41%) were men. The median of the maximum intact core tissue length was 2.4 cm (IQR, 1.8-3.5). The median total specimen length (TSL) was 6 cm (IQR, 4.3-8). The median number of complete portal tracts (CPTs) per TSL was 18 (IQR, 13- 24). The mean number of CPTs per sample length was 7.5 cm. Adverse events were uncommon (1.8%) and included abdominal pain and self-limited hematoma.
Conclusions |
EUS-guided fine-needle biopsy sampling using a novel 19-gauge core needle with a modified 1-pass 1 actuation wet suction technique (EUS-MLB) is a safe and effective way to evaluate patients with unexplained liver tests abnormalities who are undergoing EUS for exclusion of biliary obstruction.
