Article Synopsis
- A case report of a 79-year-old female revealed a preoperative intracholecystic papillary neoplasm linked to invasive carcinoma and a cholecystocolonic fistula.
- CT and endoscopic ultrasound suggested the presence of the neoplasm, leading to a biopsy that confirmed the diagnosis.
- Preoperative identification of the fistula was crucial, as it informed the surgical plan for gallbladder removal and partial resection of the transverse colon, with pathology confirming invasive carcinoma but no malignancy in the fistula.
In patients with ascites, percutaneous liver biopsy is generally contraindicated. Because endoscopic ultrasound-guided tissue acquisition (EUS-TA) allows tissue sample obtention from the digestive tract lumen, a biopsy without the intervention of ascites may prevent adverse events (AEs). This study aimed to evaluate the safety of EUS-TA for focal liver lesions in the presence of ascites.

Although the outcomes of EUS-TA for focal liver lesions have been reported to be favorable, no studies have focused on small focal liver lesions (≤2 cm). The aim of this study was to evaluate the outcomes of EUS-TA for small focal liver lesions (≤2 cm).
View Article and Find Full Text PDFObjective: This study aimed to investigate the usefulness of endoscopic ultrasound-guided tissue acquisition (EUS-TA) for diagnosing focal liver lesions in patients with a history of multiple primary malignant neoplasms.
Methods: Among patients who underwent EUS-TA for focal liver lesions between 2016 and 2022, those with a history of multiple malignant neoplasms were included. A histologically confirmed malignant tumor within the past 5 years before EUS-TA was defined as a history of malignant neoplasm.
Article Synopsis
- The caudate lobe of the liver is difficult to access for biopsy due to its deep location and surrounding major blood vessels, making traditional methods challenging.
- A study reported on seven patients aged 25-79 with lesions in the caudate lobe who successfully underwent endoscopic ultrasound-guided tissue acquisition (EUS-TA), with varied needle sizes and an average procedure time of 18 minutes.
- All patients had adequate tissue samples collected for diagnosis, identifying several types of liver tumors, and no complications were reported, suggesting EUS-TA as a preferred method for accessing these lesions.
