Single Port Robotic Liver Resection: Metastasectomy for Recurrent Fibrolamellar Hepatocellular Carcinoma.

Background: Robotic surgery has emerged as a promising approach for managing complex hepatic malignancies. This report presents a case of a single-port robotic liver resection for a patient with recurrent hepatocellular carcinoma (HCC) and metastases, focusing on the surgical technique and outcomes.

Method: An 18-year-old female with a history of left hepatectomy for fibrolamellar HCC underwent robotic liver resection using the Da Vinci SP Surgical System.

A Chondroitin Sulfate Chain of Urinary Trypsin Inhibitor Enhances Protease Inhibitory Activity of the Core Protein.

Human urinary trypsin inhibitor (UTI) is a proteoglycan composed of one core protein covalently linked to one glycosaminoglycan, which is a low sulfated chondroitin 4-sulfate. It is used as an anti-inflammatory medicine based on the protease inhibitory activity of the core protein. However, functions of the chondroitin sulfate have not been clarified.
