AbstractAbstract PDFSupplementary Material
Sarcoidosis often involves the liver. However, primary hepatic sarcoidosis confined to the liver without evidence of systemic involvement is rare. We report the case of a 37-year-old man with hepatic sarcoidosis who initially presented with elevated liver enzymes and suspicious cirrhotic nodules on computed tomography. The patient had cirrhosis but did not have portal hypertension. Based on the initial histopathologic finding of chronic granulomatous inflammation and the common clinical characteristics of sarcoidosis, he was initially diagnosed with primary biliary cholangitis, and his daily dosage of ursodeoxycholic acid was increased to 900 mg. After 14 months of treatment, his total serum bilirubin concentration was 10.9 mg/dL (upper normal limit, 1.2 mg/dL). Additionally, a transjugular liver biopsy revealed multiple noncaseating granulomas. He was diagnosed with primary hepatic sarcoidosis involving the lungs, heart, spleen, kidneys, and skin. Treatment with methylprednisolone was initiated. Two weeks later, he was started on azathioprine, and the dose of steroid was simultaneously reduced. These findings indicate the importance of including hepatic sarcoidosis as a possible diagnosis in patients with elevated liver enzymes or cryptogenic cirrhosis.

AbstractAbstract PDF
Background
This study was performed to evaluate periprocedural factors, complications, and repuncture rate of the newly developed puncture needle and compare it with the routinely used puncture needle for ultrasound (US)-guided paracentesis.
Methods
We retrospectively identified 137 patients who underwent US-guided paracentesis between July 2018 and March 2019. Among them, 82 patients underwent US-guided paracentesis with a newly developed puncture needle. The other 55 patients underwent US-guided paracentesis with a routinely used puncture needle. The periprocedural factors, complications, and repuncture rate were compared between the two groups using the Mann-Whitney U test and Fisher exact test. The repuncture-associated factors were assessed using logistic regression analysis.
Results
There were no major or minor complications in either group. The rate of repuncture was significantly lower in the group using the newly developed puncture needle compared with the group using the routinely used puncture needle (p=0.01). The duration of the procedure was significantly shorter with the newly developed puncture needle compared with the routinely used puncture needle (p=0.01). In univariate analysis, the thickness of the abdominal wall (p=0.04) and the use of the newly developed puncture needle (p=0.01) were significantly associated with the rate of repuncture. In multivariate analysis, only the use of the newly developed puncture needle was significantly associated with the rate of repuncture.
Conclusion
Using this novel puncture needle with a hard plastic sheath and plastic wings, the rate of repuncture and the duration of the procedure were decreased without complications of US-guided paracentesis.
