Background: Acute kidney injury (AKI) is a common complication in patients undergoing liver transplant (LT) and is associated with high morbidity and mortality. We aim to evaluate the pattern of urine and plasma neutrophil gelatinase-associated lipocalin (NGAL) elevation during the perioperative period of LT and to assess it as a prognostic marker for AKI progression, need for dialysis and mortality.
Methods: We assessed NGAL levels before induction of anesthesia, after portal reperfusion and at 6, 18, 24, and 48 h after surgery. Patients were monitored daily during the first week after LT.
Results: Of 100 enrolled patients undergoing liver transplant, 59 developed severe AKI based on the KDIGO serum creatinine (sCr) criterion; 34 were dialysed, and 21 died within 60 days after LT. Applying a cut-off value of 136 ng/ml, UNGAL values 6 h after surgery was a good predictor of AKI development within 7 days after surgery, having a positive predictive value (PPV) of 80% with an AUC of 0.76 (95% CI 0.67-0.86). PNGAL at 18 h after LT was also a good predictor of AKI in the first week, having a PPV of 81% and AUC of 0.74 (95% CI 0.60-0.88). Based on PNGAL and UNGAL cut-off criteria levels, time to AKI diagnosis was 28 and 23 h earlier than by sCr, respectively. The best times to assess the need for dialysis were 18 h after LT by PNGAL and 06 h after LT by UNGAL.
Conclusion: In conclusion, the plasma and urine NGAL elevation pattern in the perioperative period of the liver transplant can predict AKI diagnosis earlier. UNGAL was an early independent predictor of AKI development and need for dialysis. Further studies are needed to assess whether the clinical use of biomarkers can improve patient outcomes.
Trial Registration: Registered at Clinical Trials ( clinicaltrials.gov ) in March 24th, 2014 by title "Acute Kidney Injury Biomarkers: Diagnosis and Application in Pre-operative Period of Liver Transplantation (AKIB)" and identifier NCT02095431, retrospectively registered.

Introduction: The clinical characteristics of inflammatory bowel disease (dnIBD) diagnosed after solid organ transplant (SOT) are not well-described, particularly since the advent of biologic therapy for treatment of IBD.
Methods: We conducted a single-center, retrospective review of SOT recipients between 2010 and 2022 at the University of Minnesota Medical Center who were diagnosed with IBD after transplant.
Results: Of 89 patients at our center with IBD and a history of SOT, five (5.

Introduction: Minimally invasive surgery may confer perioperative benefit to patients with resectable Hepatocellular Carcinoma (HCC) but published data are limited. Robotic resection for HCC has recently been introduced in our institution, and the goal of this study is to benchmark patient outcomes against open and laparoscopic surgery.
Methods: A retrospective evaluation was performed of all patients undergoing liver resection for HCC in our institution between September 2012 and November 2022 using a prospectively maintained database.

Background: While hepatocellular carcinoma (HCC) remains the leading cause of liver transplant (LT) for liver tumors, indications have broadened over the years. Data regarding patient characteristics and outcomes of LT for liver tumors are limited.
Methods: From Jan-2002 to March-2022, 14,406 LT recipients for various liver tumors were identified in United Network for Organ Sharing database.
