Background: In the recent years, laparoscopic splenectomy and esophagogastric devascularization (LSD) for liver cirrhosis and portal hypertension rapidly gained the interest of hepatobiliary surgeons due to its minimal invasion. This study aimed to gather and analyze available data from the observational studies that have compared LSD and open splenectomy and esophagogastric devascularization (OSD) for liver cirrhosis and portal hypertension.
Materials And Methods: All the studies comparing LSD and OSD for liver cirrhosis and portal hypertension were searched on the available databases, including the Cochrane Central Register of Controlled Trials, Medline, Science Citation Index, EMBASE, China National Knowledge Infrastructure, Wanfang Database, and China Biomedical Database. Data were analyzed using Review Manager software version 5.0.
Results: After the literature search, a total of 17 studies were included in the meta-analysis, which involved 1093 patients: 552 in the laparoscopic group and 541 in the open group. The laparoscopic group was shown to have a lower overall postoperative complication rate (0.43; 95% confidence interval [CI; 0.29-0.64]) than the open group (P < .0001), which was not associated with heterogeneity between the studies. The laparoscopic group was shown to have a lower intraoperative blood loss (-320.62; 95% CI [-552.35 to -88.9]), shorter time of oral intake (-29.08 hours; 95% CI [-35.28 to -22.88]), and shorter hospital stay (95% CI [-6.19 to -2.19]) than those of the open group (P < .00001). The operative time of the laparoscopic group was 42.16 minutes longer (95% CI [32.20-52.11]) compared with the open group (P < .00001). There was no significant difference of hospitalization costs between the studies.
Conclusion: This meta-analysis demonstrated that laparoscopic left lateral resection is a safe and feasible option associated with a reduced overall complication rate. The current evidence suggested that it could be performed routinely in liver centers.

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 Photoacoustic microscopy (PAM) can be used to detect strong absorption from endogenous and exogenous contrast material, making it promising for detailed structural and functional imaging of hepatic sinusoids, including dynamic visualization of permeability. Purpose To evaluate whether PAM-based quantitative parameters of liver function and integrity (lacunarity, blood oxygen saturation [Sao], and Evans blue [EB] permeability) are associated with histopathologic indexes of fibrosis in a mouse model. Materials and Methods Between October 2022 and July 2023, a total of 35 male C57BL/6 mice were included in this study and received intraperitoneal injection of carbon tetrachloride to establish mouse models of progressive liver fibrosis, with seven mice in each group.

Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (POPH) are two distinct pulmonary vascular complications seen in patients with liver disease and/or portal hypertension. HPS is characterized by disturbed gas exchange and hypoxemia because of intrapulmonary vascular dilatations. POPH is defined by pulmonary arterial hypertension, which might lead to right heart failure.

Background/Aims: To evaluate invasive treatment outcomes for hepatocellular carcinoma (HCC) in patients aged over 90 years. Materials and methods: Twenty-six patients were included. Information on backgrounds, course of treatment, outcomes, and changes in Child-Pugh (CP) score and performance status (PS), as well as a comparison of treatment-related complications and 2-year survival after treatment, were retrospectively examined and compared with 311 patients aged under 90 years who were matched under the same conditions.

Liver malignancies, particularly hepatocellular carcinoma (HCC), pose a formidable global health challenge. Conventional diagnostic techniques frequently fall short in precision, especially at advanced HCC stages. In response, we have developed a novel diagnostic strategy that integrates hyperspectral imaging with deep learning.
