Abstract
Liver biopsy is a crucial diagnostic procedure for liver-related conditions. However, it is challenging to use in cases with substantial ascites or coagulopathy. Transjugular liver biopsy has been introduced as an alternative method to overcome these limitations. Although transjugular liver biopsy is commonly used for diffuse liver diseases, its application to localized tumors has been limited. We report the case of a 66-year-old male initially diagnosed with unresectable pancreatic carcinoma, who later developed liver metastasis, peritoneal dissemination, and ascites. Treatment planning required tumor re-evaluation, but percutaneous liver biopsy was not viable because of the rapid accumulation of ascites and its presence on the liver surface. However, transjugular liver biopsy was a suitable alternative, given the proximity of the tumor to the right hepatic vein. The procedure, performed under fluoroscopic and ultrasound guidance, successfully obtained 4 specimens that were promptly diagnosed as liver metastases originating from pancreatic cancer. This case underscored the effectiveness of transjugular liver biopsy in situations where percutaneous biopsy is challenging because of conditions such as ascites. The combination of ultrasound guidance and rapid specimen assessment by pathology technicians can enhance diagnostic success rates. Transjugular liver biopsy is a valuable diagnostic tool in scenarios where percutaneous access poses significant difficulties.
