Mastering the narrative: Precision reporting of risk and outcomes in liver transplantation.

Liver transplantation is associated with a high risk of postoperative complications due to the complexity of the surgical procedure, recipient disease severity and the wide range of graft quality, which remains somewhat unpredictable. However, survival rates after transplantation continue to improve and the focus has thus turned to other clinically relevant endpoints including post-transplant complications, patient quality of life and costs. Procedures like liver transplantation offer the entire spectrum of post-surgical events, even in donor-recipient constellations deemed of low risk within recently defined benchmark criteria.

Core outcome sets and benchmarking complications: Defining best practices for standardized outcome reporting in liver transplantation.

The comparison of outcomes in liver transplantation (LT) is hampered by using clinically nonrelevant surrogate endpoints and considerable variability in reported relevant posttransplant outcomes. Such variability stems from nonstandard outcome measures across studies, variable definitions of the same complication, and different timing of reporting. The Clavien-Dindo classification was established to improve the rigor of outcome reporting but is nonspecific to an intervention, and there are unsolved dilemmas specifically related to LT.

Surgeon-Scientists Going Extinct: Last Call for Action or Too Late?

Objective: To define the concept of surgeon-scientists and identify the root causes of their decline in number and impact. The secondary aim was to provide actionable remedies.

Background: Surgeons who conduct research in addition to patient care are referred to as "surgeon-scientists.

Objective: To provide improved guidance for the consistent application of the Clavien-Dindo classification (CDC) and Comprehensive Complication Index (CCI ® ) in challenging clinical scenarios.

Background: Standardized outcome reporting is key for the proper assessment of surgical procedures. A recent consensus conference recommended the CDC and the CCI ® for assessing postoperative morbidity.

Revolutionizing Liver Transplantation: Transitioning to an Elective Procedure Through Ex Situ Normothermic Machine Perfusion - A Benefit Analysis.

Objective: To assess the impact of normothermic machine perfusion (NMP) on patients, medical teams, and costs by gathering global insights and exploring current limitations.

Background: NMP for ex situ liver graft perfusion is gaining increasing attention for its capability to extend graft preservation. It has the potential to transform liver transplantation (LT) from an urgent to a purely elective procedure, which could revolutionize LT logistics, reduce burden on patients and health care providers, and decrease costs.

Revolutionizing Organ Transplantation With Robotic Surgery.

Objective: The aim of this study was to evaluate the impact of robotic techniques on organ transplantation outcomes.

Background: The evolution of organ transplantation is becoming influenced by the adoption of minimally invasive techniques, transitioning from laparoscopic to robotic methods. Robotic surgery has emerged as a significant advancement, providing superior precision and outcomes compared with traditional approaches.

Incidence of postoperative complications is underestimated if outcome data are recorded by interns and first year residents in a low volume hospital setting.

The aim of this study is to evaluate the accuracy of outcome reporting after elective visceral surgery in a low volume district hospital. Outcome measurement as well as transparent reporting of surgical complications becomes more and more important. In the future, financial and personal resources may be distributed due to reported quality and thus, it is in the main interest of healthcare providers that outcome data are accurately collected.

Full robotic versus open ALPPS: a bi-institutional comparison of perioperative outcomes.

Background: In primarily unresectable liver tumors, ALPPS (Associating Liver Partition and Portal Vein Ligation for Staged hepatectomy) may offer curative two-stage hepatectomy trough a fast and extensive hypertrophy. However, concerns have been raised about the invasiveness of the procedure. Full robotic ALPPS has the potential to reduce the postoperative morbidity trough a less invasive access.

REDISCOVER guidelines for borderline-resectable and locally advanced pancreatic cancer: management algorithm, unanswered questions, and future perspectives.

The REDISCOVER guidelines present 34 recommendations for the selection and perioperative care of borderline-resectable (BR-PDAC) and locally advanced ductal adenocarcinoma of the pancreas (LA-PDAC). These guidelines represent a significant shift from previous approaches, prioritizing tumor biology over anatomical features as the primary indication for resection. Condensed herein, they provide a practical management algorithm for clinical practice.

Portal Hemodynamics in Liver Resection and Transplantation.

The hepatic blood supply and its several homeostatic and pathologic processes has always been a matter of great interest. Many views commonly held today are derived from an earlier era, but major reorientations have occurred recently in almost all aspects of knowledge of the role and regulation of hepatic blood flow. Moreover, with the advent of liver transplantation (LT), especially living donor LT (LDLT) there has been a resurgence of interest in attempting to comprehend this deceptively simple topic.

Validation of the Clavien-Madadi Classification for Unexpected Events in Pediatric Surgery: A Collaborative ERNICA Project.

Background: The Clavien-Madadi classification is a novel instrument for the assessment and grading of unexpected events in pediatric surgery, based on the Clavien-Dindo classification. The system has been adjusted to better fit the pediatric population in a prospective single-center study. There is a need now to validate the Clavien-Madadi classification within an international expert network.

Glucose controls lipolysis through Golgi PtdIns4P-mediated regulation of ATGL.

Metabolic crosstalk of the major nutrients glucose, amino acids and fatty acids (FAs) ensures systemic metabolic homeostasis. The coordination between the supply of glucose and FAs to meet various physiological demands is especially important as improper nutrient levels lead to metabolic disorders, such as diabetes and metabolic dysfunction-associated steatohepatitis (MASH). In response to the oscillations in blood glucose levels, lipolysis is thought to be mainly regulated hormonally to control FA liberation from lipid droplets by insulin, catecholamine and glucagon.
