AI Article Synopsis
- Patients with colorectal liver metastases near the hepatic vein often undergo major surgeries, but parenchyma-sparing laparoscopy techniques show promise.
- A patient who had a tumor in contact with the middle and left hepatic veins received a limited liver resection using careful surgical techniques to minimize damage.
- The surgery was successful with minimal blood loss and a short recovery time, indicating that laparoscopic methods can be a viable alternative to more invasive procedures.
Article Abstract
Background: Patients with tumors involving the hepatic vein (HV) at the caval confluence (CC) usually receive major hepatectomies or HV grafting. For colorectal liver metastases (CLM), tumor-vessel detachment (R1vasc) has proven to be oncologically adequate. However, parenchyma-sparing R1vasc surgery has usually been confined to the open approach. The technical tricks for accomplishing this kind of surgery in laparoscopy are disclosed.
Methods: A patient with a CLM in contact with the middle HV (MHV) and left HV (LHV) at the CC underwent liver resection. No signs of vascular invasion were observed at preoperative imaging. On the basis of the low rate of tumor-vessel regression after chemotherapy, technical feasibility, and low tumor burden, patient was considered for upfront surgery. Surgery consisted in: (1) left liver mobilization with full exposure of the CC; (2) identification of the common trunk's root and its encirclement by tape; (3) the use of ultrasound to rule out HV invasion and to define a resection area favoring a transection plane smoothly approaching the point of vascular contact; and (4) careful vascular detachment by blunt dissection in a caudocranial fashion to separate the lesion from HVs.
Results: A limited resection of segments, four superior and two with MHV-LHV detachment, was performed. Operation time was 285 min, with 52 min of cumulative Pringle time and 20 ml of blood loss. Postoperative course was uneventful. The in-hospital stay was 6 days.
Conclusion: Similarly to open surgery, laparoscopic R1vasc surgery for CLM at CC is feasible and represents an alternative to major hepatectomy. HV control by tape is recommended to manage any bleeding that may occur during tumor-vessel detachment.

Neuroendocrine tumors (NENs) originate from neuroendocrine cells and predominantly occur in the gastrointestinal tract, lungs, and pancreas. Although the liver is commonly involved in NEN metastasis, primary hepatic neuroendocrine tumors (PHNETs) are rare. Herein, we report a case of a 52-year-old female who presented with slowly enlarging, cystic, multiple PHNETs.

Background: While evidence from preclinical and observational cohort studies have suggested potential disparities in tumour behaviour associated with the choice of intra-operative anaesthetics, clinical evidence of tumour recurrence and metastasis remains inconclusive. We aimed to compare the impact of intra-operative anaesthesia on oncologic outcomes following hepatectomy for hepatocellular carcinoma.
Methods: Adult patients scheduled for elective hepatectomy for hepatocellular carcinoma were assigned randomly (1:1) to either propofol-based total intravenous anaesthesia or sevoflurane-based inhalational anaesthesia.

Nucleotide availability is crucial for DNA replication and repair; however, the coordinating mechanisms in vivo remain unclear. Here, we show that the circadian clock in the liver controls the activity of the pentose phosphate pathway (PPP) to support de novo nucleotide biosynthesis for DNA synthesis demands. We demonstrate that disrupting the hepatic clock by genetic manipulation or mistimed feeding impairs PPP activity in male mice, leading to nucleotide imbalance.

Multimorbidity is characterized by the presence of at least 3 chronic diseases with a prevalence of more than 50% of patients over 60 years old. The Charlson comorbidity index (CCI) enables a description of the severity of the multimorbidity and also provides a correlation with the postoperative outcome after liver resection. According to this, multimorbid patients are at increased risk of morbidity and mortality after liver resection, mostly due to postoperative liver failure.
