Prediction of complexity and complications of laparoscopic liver surgery: The comparison of the Halls‐score to the IWATE‐score in 100 consecutive laparoscopic liver resections
BACKGROUND The development of laparoscopic liver surgery is slower than in other disciplines. Two different scoring systems have been proposed to estimate difficulty of laparoscopic liver resections (LLR) preoperatively. The aim of this analysis was to compare these two scores in an independent patient cohort regarding the predictability of morbidity. METHODS All LLRs performed between 01/2011 until 01/2019 were identified from our prospective institutional database. Patient characteristics as well as intra- and postoperative data were analyzed. Postoperative complications were graded according to Dindo-Clavien classification. Difficulty of LLR was classified using IWATE- and Halls-score. R…
Expression and prognostic significance of insulin‑like growth factor-2 receptor in human hepatocellular carcinoma and the influence of transarterial chemoembolization
Hepatocellular carcinoma (HCC) is one of the most common human malignancies, the incidence of which is growing worldwide. The prognosis of HCC is very poor and it is often accompanied by a high rate of recurrence. Conventional chemotherapeutic approaches are largely inefficient. In order to develop novel effective methods for the early detection and prognosis of HCC, novel markers and therapeutic targets are urgently required. The present study focused on the effects of the expression of the tumor suppressor gene insulin‑like growth factor‑2 receptor (IGF2R) on patient survival and tumor recurrence in patients with HCC; this study paid specific attention to the influence of transarterial ch…
Immunonutritive Scoring in Patients With Hepatocellular Carcinoma Undergoing Transarterial Chemoembolization: Prognostic Nutritional Index or Controlling Nutritional Status Score?
ObjectivesThe Prognostic Nutritional Index (PNI) and Controlling Nutritional Status (CONUT) score are immunonutritive scoring systems with proven predictive ability in various cancer entities, including hepatocellular carcinoma (HCC). We performed the first evaluation of the CONUT score for patients undergoing transarterial chemoembolization (TACE) and compared CONUT and PNI in the ability to predict median overall survival (OS).MethodsBetween 2010 and 2020, we retrospectively identified 237 treatment-naïve patients with HCC who underwent initial TACE at our institution. Both scores include the albumin level and total lymphocyte count. The CONUT additionally includes the cholesterol level. …
Influence of Lymphangio (L), Vascular (V), and Perineural (Pn) Invasion on Recurrence and Survival of Resected Intrahepatic Cholangiocarcinoma
(1) Background: Intrahepatic cholangiocarcinoma (ICC) is a rare malignancy. Besides tumor, nodal, and metastatic status, the UICC TNM classification describes further parameters such as lymphangio- (L0/L1), vascular (V0/V1/V2), and perineural invasion (Pn0/Pn1). The aim of this study was to analyze the influence of these parameters on recurrence and survival. (2) Methods: All surgical explorations for patients with ICC between January 2008 and June 2018 were collected and further analyzed in our institutional database. Statistical analyses focused on perineural, lymphangio-, and vascular invasion examined histologically and their influence on tumor recurrence and survival. (3) Results: Of 2…
Leberresektionen können bei vorsichtiger Patientenselektion auch in Zirrhose sicher durchgeführt werden
Zusammenfassung Hintergrund Das hepatozelluläre Karzinom (HCC) ist der häufigste maligne Lebertumor in einer Leberzirrhose. Neben der Lebertransplantation stellt die Leberresektion in kompensierter Zirrhose eine kurative Therapieoption dar, die jedoch mit einer höheren postoperativen Morbidität und Mortalität einhergeht. Patienten Es wurden 108 Patienten identifiziert, die mit einer Leberzirrhose im Zeitraum von Januar 2008 bis Dezember 2019 an der Universitätsmedizin Mainz eine Leberresektion erhalten haben. Im gleichen Zeitraum wurden 185 Resektionen wegen eines HCC in nicht zirrhotischer Leber durchgeführt. Als weitere Kontrollgruppe dienten 167 Resektionen wegen kolorektaler Lebermetast…
Cirrhosis risk score of the donor organ predicts early fibrosis progression after liver transplantation.
Background & Aims: Fibrosis progression (FP) after liver transplantation (LT) increases morbidity and mortality. Biomarkers are needed for early prediction of FP. A recipient’s seven-gene cirrhosis risk score (CRS) has been associated with FP, especially in non-transplant cohorts. A broader validation of CRS, including the genotype of the donor-organ and HCV-negative patients is lacking. We therefore analyzed the impact of donor- and recipient-specific genotypes on FP after LT in a large cohort of HCV-positive and -negative patients.Method: Genotyping from liver biopsies (n=201 donors) and peripheral blood (n=442 recipients) was performed. Cirrhosis risk score was correlated with FP at …
Immunonutritive Scoring for Patients with Hepatocellular Carcinoma Undergoing Transarterial Chemoembolization: Evaluation of the CALLY Index
The novel CRP–albumin–lymphocyte (CALLY) index is an improved immunonutritive scoring system, based on serum C-reactive protein (CRP), serum albumin, and the lymphocyte count. It has shown promise as a prognostic index for patients with hepatocellular carcinoma (HCC) undergoing resections. This study evaluated the prognostic ability of the CALLY index for patients with HCC undergoing transarterial chemoembolization (TACE). We retrospectively identified 280 treatment-naïve patients with HCC that underwent an initial TACE at our institution, between 2010 and 2020. We compared the CALLY index to established risk factors in univariate and multivariate regression analyses for associations with m…

Urinary ethyl glucuronide (uEtG) as a marker for alcohol consumption in liver transplant candidates: a real-world cohort
In order to reduce alcohol relapse after liver transplantation (LT), the German national guidelines for waiting-list maintenance and organ allocation demand a minimum 6-month period of alcohol abstinence pre-LT, confirmed by measuring urinary ethyl glucuronide (uEtG). Between January 2015 and June 2016, uEtG was measured at least once in 339 cirrhotic patients with an indication for LT at the University Medical Center Mainz. uEtG was measured with an enzyme-linked immunosorbent assay (ELISA) screening test (cutoff value: 500 µg/L). For uEtG values ≥ 500 µg/L, liquid chromatography-mass spectrometry (LC-MS/MS) was performed as a confirmatory assay. Data were collected prospectively in a tra…
Outcome of liver transplantation for hepatopulmonary syndrome: a Eurotransplant experience.
Hepatopulmonary syndrome (HPS) is a pulmonary vascular complication of liver disease that affects up to 30% of patients with cirrhosis [1]. Intrapulmonary vascular dilatations and shunts result in gas exchange abnormalities, ranging from elevated alveolar-arterial oxygen gradients with no hypoxemia to very severe hypoxemia [1, 2]. Currently, liver transplantation (LT) is the only treatment option [3]. The Model for End-Stage Liver Disease (MELD) is a scoring system for assessing liver disease severity that has been validated to predict the 3-months waitlist mortality, and is used by Eurotransplant for prioritising allocation of liver transplants [4]. Footnotes This manuscript has recently b…
Refining Prognosis in Chemoembolization for Hepatocellular Carcinoma: Immunonutrition and Liver Function
A combination of albumin-bilirubin (ALBI) grading and the Prognostic Nutritional Index (PNI) was identified recently as a highly predictive tool for patients with hepatocellular carcinoma (HCC) undergoing tumor ablation. The present study evaluated this combination in patients undergoing transarterial chemoembolization (TACE). Between 2010 and 2020, 280 treatment-naïve patients were retrospectively identified. The influence of ALBI grade, PNI and the novel ALBI-PNI on the median overall survival (OS) was assessed. In the next step, the prognostic ability of the combined approach was compared to established scoring systems. Both ALBI grade 2−3 and a low PNI were highly predictive for median …
High pretreatment static and dynamic alpha‐fetoprotein values predict reduced overall survival in hepatocellular carcinoma
Abstract Background Hepatocellular carcinoma is one of the most lethal cancers worldwide. Novel prognostic and/or predictive biomarkers are urgently needed to improve patient management. Alpha‐fetoprotein (AFP) is a well‐established and widely used biomarker for hepatocellular carcinoma. However, diagnostic accuracy of static AFP values is limited and the clinical potential is a matter of ongoing scientific discussion. Objective We here evaluated the prognostic impact of pretreatment static and dynamic AFP variables on overall survival of hepatocellular carcinoma patients in a Western cohort. Methods Patients with confirmed hepatocellular carcinoma (n = 809) treated at the Johannes Gutenber…
Progression of transthyretin (TTR) amyloidosis in donors and recipients after domino liver transplantation-a prospective single-center cohort study
Liver transplantation (LT) is the first-line therapy in patients with transthyretin (TTR) amyloidosis and progressive familial amyloid polyneuropathy (FAP). Explanted organs from these patients can be used for domino liver transplantation (DLT). After DLT, de novo amyloidosis may develop in domino recipients (DR). Data were collected prospectively in a transplant database. Electroneurography by nerve conduction velocity (NCV), quantitative sensory testing, heart rate variability (HRV), sympathetic skin response, orthostatic reaction (tilt table test), transthoracic echocardiography, cardiac MRI and organ biopsy results were evaluated. The cohort included 24 FAP- (11 Val30Met, 13 nonVal30Met…
Associated Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) Registry: What Have We Learned?
In 2007, the first associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure was performed in Regensburg, Germany. ALPPS is a variation of two-stage hepatectomy to induce rapid liver hypertrophy allowing the removal of large tumors otherwise considered irresectable due to a too small future liver remnant. In 2012, the international ALPPS registry was created, and it now contains more than 1,000 cases. During the past years, improved patient selection and refinements in operative techniques, in particular, less invasive approaches such as Partial ALPPS, Tourniquet ALPPS, Ablation-assisted ALPPS, Hybrid ALPPS or Laparoscopic or Robotic approaches, have resu…

How to Handle Arterial Conduits in Liver Transplantation? Evidence From the First Multicenter Risk Analysis
OBJECTIVE: The aims of the present study were to identify independent risk factors for conduit occlusion, compare outcomes of different AC placement sites, and investigate whether postoperative platelet antiaggregation is protective. BACKGROUND: Arterial conduits (AC) in liver transplantation (LT) offer an effective rescue option when regular arterial graft revascularization is not feasible. However, the role of the conduit placement site and postoperative antiaggregation is insufficiently answered in the literature. STUDY DESIGN: This is an international, multicenter cohort study of adult deceased donor LT requiring AC. The study included 14 LT centers and covered the period from January 2…

Sarcopenia as prognostic factor for survival after orthotopic liver transplantation
Background and aim Body composition has emerged as a prognostic factor for end-stage liver disease. We therefore investigated muscle mass, body fat and other clinical-pathological variables as predictors of posttransplant survival. Methods A total of 368 patients, who underwent orthotopic liver transplantation (OLT) at our institution, were assessed prior to OLT and followed for a median of 9.0 years (range 2.0-10.0 years) after OLT. Psoas, erector spinae and the combined paraspinal muscle area, as well as the corresponding indices normalized by body-height squared, were quantified by a lumbar (L3) cross-sectional computed tomography. In addition, absolute body fat and bone density were est…
Liver Resection for Intrahepatic Cholangiocarcinoma—Single-Center Experience with 286 Patients Undergoing Surgical Exploration over a Thirteen Year Period
Background: Intrahepatic cholangiocarcinoma (iCCA) accounts for about 10% of primary liver cancer. Surgery is the only potentially curative treatment. We report on our current series of 229 consecutive hepatic resections for iCCA, which is one of the largest Western single-center series published so far. Methods: Between January 2008 to December 2020, a total of 286 patients underwent 307 surgical explorations for intended liver resection of iCCA at our department. Data were analyzed with regard to (1) preoperative treatment of tumor, (2) operative details, (3) perioperative morbidity and mortality, (4) histopathology, (5) outcome measured by tumor recurrence, treatment of recurrence and su…
Pringle maneuver increases the risk of anastomotic leakage after colonic resection in rats.
Abstract Background Many centers use the Pringle's maneuver during liver resections. Since this maneuver might impair healing of bowel anastomoses, we evaluated its influence on the healing of colonic anastomosis in rats. Methods Male Wistar rats underwent median laparotomy and sigmoid resection with end-to-end anastomosis under inhalation anesthesia. Thereafter, rats received a 25 minutes Pringle's maneuver (PM, group 1) or were kept under anesthesia for the same period of time (group 2). The anastomotic bursting pressure (BP) was measured on postoperative days (POD) 3, 6 and 9. Hematoxylin and Eosin (H&E) staining was used for histopathological evaluation of the anastomosis. The Mann-Whit…
Imaging-Based Preoperative Planning
Liver resection in the treatment of colorectal liver metastases, as for any other primary or secondary liver tumor, needs to be oncologically effective and surgically safe. Both goals need equal consideration, and imaging-based preoperative planning is paramount for achieving each of them. Preoperative imaging should ideally identify all metastatic lesions in the liver, as well as extrahepatic disease. Furthermore, it should provide an anatomical roadmap with the exact localization of each lesion within the segmental hepatic anatomy, and its proximity to adjacent vasculo-biliary structures, to allow for proper resection leaving the patient with a sufficiently functioning liver remnant. This…
