Abstract Background Liver surgery carries a high risk of complications due to the complex interplay of patient-related factors, disease characteristics, and liver function. Expertise is essential for healthcare professionals managing hepatobiliary patients. This European consensus provides evidence-based guidance on selected aspects of peri- and postoperative care. Methods A modified Delphi process was used to achieve consensus, with a 70% agreement threshold. The expert panel comprised hepatobiliary surgeons, anaesthetists, hepatologists, a specialist nurse, and a physiotherapist. A systematic literature search was conducted in PubMed/MEDLINE, Embase, Web of Science, and Cochrane databases. Six topics were addressed: thromboprophylaxis; perioperative antibiotics; prehabilitation/nutrition/mobilization; bile leak including bilioenteric anastomosis leaks; post-hepatectomy haemorrhage; and post-hepatectomy liver failure (PHLF). Evidence appraisal and statement development followed Scottish Intercollegiate Guidelines Network methodology. A patient representative reviewed the guideline. Results Searching the literature yielded 204 included publications from an initial 6514. Thirty-two statements were formulated with a median evidence level of 2. Evidence strength varied by topic with noticeably lower evidence levels in complex surgery settings and less prevalent conditions. In some topics, study heterogeneity and specific inclusion criteria resulted in conditional recommendations, despite high-level evidence. Notably, the weakest evidence was found for perioperative thromboprophylaxis and PHLF management. Strong recommendations were formulated for prehabilitation, early postoperative mobilization, and avoidance of routine drain use. Several evidence gaps warranting multicentre studies were identified. Conclusion Optimizing peri- and postoperative care after liver resection remains challenging. Standardizing key practices and addressing evidence gaps through collaborative research are vital to improve outcomes.

Background and Aims: Hypothermic oxygenated machine perfusion (HOPE) improves outcomes in orthotopic liver transplantation (OLT), but reliance on University of Wisconsin machine perfusion solution (UW-MPS) increases costs and logistical burden. Histidine-tryptophan-ketoglutarate (HTK) has potential as a single-solution alternative for HOPE. This study evaluated the safety and efficacy of HTK versus UW-MPS during HOPE. Methods: A retrospective, propensity score-matched cohort study including 46 patients who received donation after brain death (DBD) grafts that were preserved with HOPE at the Medical University of Vienna between May 2018 and October 2024 was conducted. A total of 23 patients received grafts perfused with HTK; another 23 patients transplanted with organs perfused with UW-MPS were matched based on recipient age and sodium model of end-stage liver disease score, donor age and sex, cold ischemia time, and perfusion time. Postoperative outcomes, perfusion parameters, and cost differences were assessed. Results: The HTK and UW-MPS cohorts demonstrated comparable perfusion dynamics and vascular resistance. While arterial pressure and flow were higher in the UW-MPS group, clinical outcomes—including early allograft dysfunction (47.8% each), ICU stay, and comprehensive complication index—were statistically similar. A trend toward fewer biliary complications (13.0% vs. 30.4%) and reduced hemodialysis requirement (17.4% vs. 30.4%) was observed in the HTK group. Use of HTK reduced perfusion-related costs by approximately EUR 560 per procedure. Conclusion: HTK is a viable alternative to UW-MPS during HOPE in OLT of DBD grafts, offering comparable short-term outcomes and relevant cost savings. Prospective studies are warranted to validate these findings and explore broader applications of single-solution perfusion strategies.

Abstract Importance and Objective Pancreatic cancer can lead to severe stenosis of the portomesenteric venous (PV/SMV) confluence due to extrinsic compression or direct invasion. This can result in venous hypertension associated with post-prandial abdominal pain, gastrointestinal bleeding, and ascites. In patients with unresectable tumors, transhepatic PV/SMV stenting has been reported; however, its safety and efficacy are poorly understood. Design, Setting and Participants All unresectable pancreatic cancer patients referred to Interventional Radiology to undergo palliative transhepatic PV/SMV stenting (2011–2024) were collected. Patient demographics, CT scans, transhepatic venograms, and clinical outcomes were reviewed. Intervention, Main Outcomes and Results In total, 129 patients were included; 92% had pancreatic ductal adenocarcinoma. Tumors were unresectable due to unreconstructable vascular involvement, metastatic disease, or poor performance status. Nearly 81% were symptomatic, while the remaining 24 asymptomatic patients presented with significant venous hypertensive varices and collaterals on imaging. Complete venous occlusion was seen in 39% of patients at the PV, the SMV, or the PV/SMV confluence; 97% of procedures were successful, with 4 technical failures at obtaining distal venous wire access. Adverse events occurred in 4 patients. Radiological follow-up was available in 94% of patients. Post-procedural primary stent patency was 80% at a median follow-up time of 20 months. Follow-up was available in 102 of the 105 symptomatic patients, with 85% reporting an improvement in symptoms. Conclusions and Relevance Palliative transhepatic PV/SMV stenting is a technically feasible and safe procedure in well-selected patients. Symptoms improvement can be seen in most patients. High-volume centers should consider this technique for patients with unresectable tumors who present with symptomatic stenosis or short segment occlusion.
