Summary: This study found that the homozygous MBOAT7 rs641738 polymorphism is associated with a reduced extraction efficiency of (C-13)-methacetin from the portal flow, indicating the presence of early liver dysfunction independently from liver fibrosis. Moreover, liver steatosis worsens (C-13)-methacetin extraction efficiency. The mechanisms of interaction between external factors and multiple gene polymorphisms (including MBOAT7) need to be further explored for primary prevention and novel therapeutic strategies.

Summary: The interaction between body fat accumulation, insulin resistance, and NAFLD is associated with decreased hepatic extraction efficiency and impaired liver microsomal function. Dietary models and lifestyles have a minor role in promoting functional changes.

Summary: This study aimed to compare future liver remnant function (FLR-F) assessed by hepatobiliary scintigraphy (HBS) with FLR volume (FLR-V) in predicting posthepatectomy liver failure (PHLF). The study found that FLR function gain after portal vein embolization or liver venous deprivation could predict PHLF effectively.

Summary: Fontan-associated liver disease is a common issue in Fontan patients. This study evaluated the maximal liver function capacity in adult Fontan patients using LiMAx (R) test. The study found that most patients had normal liver function capacity and there was no clear correlation between liver function capacity and FALD severity.

Summary: Preoperative gadoxetic acid-enhanced MRI with computer-aided virtual hepatectomy can accurately assess regional liver function reserve to predict short-term outcomes after major hepatectomy for HCC. Quantitative regional liver function assessed by gadoxetic acid-enhanced MRI is an independent risk factor for postoperative major complications.

Summary: The estimation of hepatic clearance may help predict posthepatectomy liver failure (PHLF) and major complications in patients undergoing resection of hepatocellular carcinoma (HCC). Factors such as hepatic clearance of the remnant liver and intraoperative bleeding were found to be significant risk factors for both PHLF and major complications.

Summary: The C-13-methacetin breath test is a promising tool for predicting outcomes in adults with acute liver failure and acute liver injury. The PDR peak values are significantly correlated with survival rates, and the test may aid in medical decision making for critically ill patients.

Summary: The impact of albumin-bilirubin (ALBI) score at post-hepatectomy hepatocellular carcinoma (HCC) recurrence on survival after recurrence (SAR) was investigated in this study. It was found that higher ALBI scores at recurrence were associated with poorer SAR. Factors such as ALBI scores at hepatectomy and post-hepatectomy liver failure (PHLF) & grade B were also found to be related to the ALBI score at recurrence.

Summary: This study established a new segmentation system and a partial liver transplantation model for pigs. The new pig model based on this system can be used as a valuable educational tool for training in living donor liver transplantation, providing a more realistic simulation before performing the actual surgery.

Summary: This study evaluated the association between future liver remnant volume (FLRV) and post-hepatectomy liver failure (PHLF). The results showed a significant decrease in FLRV% in PHLF patients, with over half of them having FLRV% < 30%. Therefore, the authors recommend risk stratification and additional CT volumetry for high-risk patients prior to major hepatectomy.

Summary: Microwave ablation (MWA) is an effective minimally invasive treatment for solid tumors, with this study focusing on short-term volume changes in ablated liver tissue in a porcine model using contrast-enhanced computer tomography (CECT). The results showed a significant reduction in volume of the ablated areas within 2 hours post-MWA, indicating the need for further investigation in clinical settings.

Summary: The study aimed to investigate the role of the German Classification of Diverticular Disease in the clinical progression and treatment of different types of diverticular disease. The results showed that stratifying patients into type 2a and 2b based on abscess size is reasonable, with type 2b patients requiring surgery and type 2a patients potentially benefiting from conservative treatment. Sigmoid colectomy in patients with type 3b may lead to long-term gastrointestinal symptoms.

Summary: The interreader agreement for NI-RADS categories assigned to the primary site was moderate, substantial for the neck, and almost perfect for DWI of the primary site. Interreader agreement for the primary site was particularly low in cases of cancer recurrence and when certain categories were combined. Intrareader agreement was considerably lower for NI-RADS categories of the primary site than for the neck and DWI of the primary site.

Summary: In this study, a total of 198 patients who underwent secondary skin closure following NPWT for infected abdominal wounds were analyzed and compared to 67 patients who received open wound treatment after NPWT. The results showed that surgical skin closure following NPWT is a good and safe alternative to open wound treatment, reducing outpatient wound therapy, improving quality of life for patients, and lowering healthcare costs.

Summary: During the COVID-19 pandemic, there was a decrease in adult appendicitis cases and an increase in pediatric cases. The rate of open appendectomies showed a slight increase while antibiotic treatment rate significantly rose. Adults had higher rates of complicated appendicitis, and there were no significant changes in time to consultation and length of hospital stay.

Summary: This study aimed to compare the risk of surgical site infections (SSIs) in intra-abdominal infections (IAIs) after the implementation of a new local perioperative antibiotic prophylaxis (PAP) guideline. The study found that the rate of SSIs was slightly higher in the cefazolin (CFZ) group compared to the cefuroxime (CXM) group, while the rate of other postoperative infections was significantly higher in the CFZ group.
