Purpose: Here, we analyse the technical modification of the ALPPS procedure, ligating the middle hepatic vein during the first step of the operation to enhance remnant liver hypertrophy.
Methods: In 20 of 37 ALPPS procedures, the middle hepatic vein was ligated during the first step. Hypertrophy of the functional remnant liver volume was assessed in addition to postoperative courses.
Results: Volumetric analysis showed a significant volume increase, especially for patients with colorectal metastases. Pre-existing liver parenchyma damage (odds ratio = 0.717, p = 0.017) and preoperative chemotherapy were found to be significant predictors (odds ratio = 0.803, p = 0.045) of higher morbidity and mortality. In addition, a survival benefit for maintenance of middle hepatic vein was shown.
Conclusion: This technical modification of the ALPPS procedure can accentuate future liver remnant volume hypertrophy. The higher morbidity and mortality observed are most likely associated with pre-existing parenchymal damage within this group.

Sepsis is a major cause of morbidity and mortality worldwide. Among the various types of end-organ damage associated with sepsis, hepatic injury is linked to significantly higher mortality rates compared to dysfunction in other organ systems. This study aimed to investigate potential biomarkers of hepatic injury in sepsis patients through a multi-center, case-control approach.

Background: Hepatic sarcomatoid carcinoma (HSC) and hepatic sarcoma (HS) are rare malignancies. Without pathology, the differential diagnosis between these two tumors is difficult due to their frequent overlaps in clinical presentations and imaging features. Currently, there are limited analyses about the ultrasound (US), contrast-enhanced ultrasound (CEUS) and contrast-enhanced computer tomography (CECT) characteristics of HSC and HS.

This study investigated the association between NAFLD and liver fibrosis and the ratio of gamma-glutamyl transferase to high-density lipoprotein cholesterol (GGT/HDL-C). In this cross-sectional study, we included 4764 subjects who participated in the National Health and Nutrition Examination Survey (NHANES) during 2017-2018. Adjusted multivariate logistic regression analysis was utilized to evaluate the relationships between GGT/HDL-C levels and NAFLD, fatty liver degree, and liver fibrosis.

Near Infrared Spectroscopy (NIRS) is a non-invasive optical technique allowing a continuous measurement of brain's hemoglobin (Hb) saturation in oxygen (rSO2). It is a marker of cerebral insult and rSO2 < 50% is associated with increased neurological impairment. Cirrhotic patients with gastrointestinal bleeding (GIB) often develop hepatic encephalopathy (HE).

The role of pre-treatment HBV DNA levels on the prognosis of hepatitis B virus-related decompensated cirrhosis is unclear. This study investigated the effects of pre-treatment HBV DNA and other determinants on short-term and long-term survival of chronic hepatitis B (CHB) patients with decompensated cirrhosis. A total of 278 cirrhotic decompensated CHB patients treated with entecavir or tenofovir disoproxil fumarate were retrospectively enrolled.
