Endoscopic Ultrasound Versus CT Scan for Detection of the Metastases to the Liver

Abstract

In comparison with the CT scan, there was trend in favor of EUS/EUS-FNA for the superior diagnostic accuracy. EUS was distinctly superior to the CT scan in detecting the number of metastatic lesions. EUS-FNA was also useful to identify the nature of lesions that were too small to be characterized on the CT scan.

Correlation of liver and pancreas endoscopic ultrasonography-guided fine-needle aspiration biopsy in patients with a primary pancreatic lesion

“…1,2 EUS FNA of the liver has been used to evaluate specific liver lesions and these have included both primary and metastatic malignancies. [3][4][5][6][7][8][9] It has been shown to be safe, efficacious, and diagnostic. 10 This study identified 102 cases where both the pancreas and liver were biopsied concomitantly.…”

Indications, Preparation, Risks, and Complications

“…Studies have shown that EUS can identify small metastatic lesions that were not identified on CT, including left lobe liver metastases, perivascular cuffing by tumor, and malignant involvement of celiac ganglia. [18][19][20] The ability to obtain tissue specimens from these sites or from the primary pancreatic mass is increasingly important. Pancreatic mass lesions may be adenocarcinoma, other neoplasms such as neuroendocrine tumors or metastases, or benign conditions such as autoimmune pancreatitis, and these lesions cannot always be differentiated by clinical findings, imaging, and laboratory tests.…”

EUS in the Evaluation of Gastric Tumors
