Hepatocellular carcinoma (HCC) patients have chronic liver disease with functional deterioration and multicentric oncogenicity. Liver surgeries for the patients should be planned on both oncological effects and sparing liver function. In colorectal patients with post-chemotherapy liver injury and multiple bilateral tumors, handling multiple tumors in a fragile/easy-to-bleed liver is an important issue. Liver surgery for biliary tract cancers is often performed as a resection of large-volume functioning liver with extensive lymphadenectomy and bile duct resection/reconstruction. Minimally invasive liver surgery (MILS) for HCC is applied with the advantages of laparoscopic for cases of cirrhosis or repeat resections. Small anatomical resections using the Glissonian, indocyanine green-guided, and hepatic vein-guided approaches are under discussion. In many cases of colorectal liver metastases, MILS is applied combined with chemotherapy owing to its advantage of better hemostasis. Two-stage hepatectomy and indocyanine green-guided tumor identification for multiple bilateral tumors are under discussion. In the case of biliary tract cancers, MILS with extensive lymphadenectomy and bile duct resection/reconstruction are developing. A robot-assisted procedure for dissection of major vessels and handling fragile livers may have advantages, and well-simulated robot-assisted procedure may decrease the difficulty for biliary tract cancers.

Background: Robotic hepatectomy has been increasingly adopted for the treatment of hepatocellular carcinoma (HCC). However, the ideal technique of parenchymal transection in robotic hepatectomy has been a matter of ongoing debate in literature.

Patients And Methods: In this video, we demonstrate the technique of robotic anatomical segment VIII resection using the scissor hepatectomy technique for parenchymal transection on a 75-year-old male patient with a solitary HCC lesion.

Background: Larsucosterol is a DNA methyltransferase inhibitor in development for alcohol-associated hepatitis (AH), a disease for which there is no approved therapy.

Methods: In this phase 2b trial, patients with severe AH were randomly assigned 1:1:1 to receive 30 mg or 90 mg of larsucosterol or placebo; a second dose was administered after 72 hours if the patient remained hospitalized. All patients received supportive care as determined by investigators.

AbstractMorning Report is a time-honored tradition where physicians-in-training present cases to their colleagues and clinical experts to collaboratively examine an interesting patient presentation. The Morning Report section seeks to carry on this tradition by presenting a patient's chief concern and story, inviting the reader to develop a differential diagnosis and discover the diagnosis alongside the authors of the case. This report examines the story of a 26-year-old woman who developed acute hepatocellular liver injury following a cesarean delivery for fetal distress.
