Background: There have been no studies on laparoscopic anatomical hemihepatectomy guided by the middle hepatic vein combined with transhepatic duct lithotripsy for the treatment of complex hemihepatolithiasis. This study aimed to investigate the safety and efficacy of laparoscopic anatomical hemihepatectomy guided by the middle hepatic vein combined with transhepatic duct lithotomy to treat complex hemihepatolithiasis.
Methods: The clinical data for patients who underwent laparoscopic anatomical hemihepatectomy for complex intrahepatic bile duct stones with or without common bile duct stones from January 2016 to June 2020 were prospectively collected. Patients were divided into 2 groups according to surgical approach: laparoscopic anatomical hemihepatectomy guided by the middle hepatic vein (middle hepatic vein group) or laparoscopic anatomical hemihepatectomy not guided by the middle hepatic vein (nonmiddle hepatic vein group). The safety and short-term and long-term efficacy outcomes of the 2 groups were compared with 1:1 propensity score matching.
Results: With only a slightly longer operative time (P = .006), the initial and final stone residual rates in the middle hepatic vein group (n = 70) were significantly lower than those in the nonmiddle hepatic vein group (n = 70) (P = .002, P = .009). The bile leakage rate and stone recurrence rate were also significantly lower (P = .001, P = .001).
Conclusion: Laparoscopic anatomical hemihepatectomy guided by the middle hepatic vein is safe and effective for treating intrahepatic bile duct stones and can decrease the stone residual rate, reduce the bile leakage rate and stone recurrence rate, and accelerate early recovery. However, owing to the complicated technical requirements for surgeons and anesthesiologists, use of the procedure is limited to large and experienced medical centers.

Background: Neuregulin (NRG) family is involved in energy metabolism, among which NRG1 is a neuregulin proved to play a protective role in MAFLD cells. But the presice echanism has not been fully illustrated. This study aimed to investigate the role of NRG1 via the ERK/SIRT1 signaling in the pathogenesis of MAFLD.

Purpose: To assess the activity and toxicity of hepatic arterial infusion chemotherapy (HAIC)+tislelizumab+lenvatinib (HAIC+tisle+len) in hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) type IV (Vp4 hCC) in a real-world context.
Methods: Fifty-five patients, with Vp4 hCC receiving HAIC+tisle+len therapy from April 2021 to December 2022, were analyzed retrospectively. Data on patient characteristics, adverse events (AEs), treatment, and survival were collected.

Study: This prospective study included patients with LC undergoing hepatic vein catheterization and pressure measurement at the hospital from May 2021 to January 2023.
Machine learning prediction of hepatic encephalopathy for long-term survival after transjugular intrahepatic portosystemic shunt in acute variceal bleeding.

Department of Radiology, Nanfang Hospital, Southern Medical University, Guangzhou 510151, Guangdong Province, China.
Background: Transjugular intrahepatic portosystemic shunt (TIPS) is an effective intervention for managing complications of portal hypertension, particularly acute variceal bleeding (AVB). While effective in reducing portal pressure and preventing rebleeding, TIPS is associated with a considerable risk of overt hepatic encephalopathy (OHE), a complication that significantly elevates mortality rates.
Aim: To develop a machine learning (ML) model to predict OHE occurrence post-TIPS in patients with AVB using a 5-year dataset.
