Introduction: Liver resection has been associated with high morbidity and mortality, and the most serious complication is liver failure. Patient evaluation is limited to risk scales. The 50-50 criteria and bilirubin peak>7mg/dl have been used as mortality predictors.
Aim: The aim of this study was to determine the risk factors associated with morbidity and mortality for liver resection in our population.
Material And Methods: A retrospective study was carried out on 51 patients that underwent liver resection. Sociodemographic variables, pathology, and the surgical act were analyzed, together with morbidity and mortality and their associated factors.
Results: Fifty-one patients, 23 men and 28 women, were analyzed. They had a mean age of 51.4±19.13 years, 64.7% had concomitant disease, and their mean MELD score was 7.49±1.79. The mean size of the resected lesions was 7.34±3.47cm, 51% were malignant, and 34 minor resections were performed. The Pringle maneuver was used in 64.7% of the cases and the mean blood loss was 1,090±121.76ml. Morbidity of 25.5% was associated with viral hepatitis infection, greater blood loss, transfusion requirement, the Pringle maneuver, lower hemoglobin and PTT values, and higher MELD, INR, bilirubin, and glucose values. A total 3.9% mortality was associated with hyperbilirubinemia, hyperglycemia, and greater blood loss and transfusions.
Conclusions: The main risk factors associated with the morbidity and mortality of liver resection in our population were those related to the preoperative biochemical parameters of the patient and the factors that occurred during the surgical act.

Liver resection in stage 0-A HCC in segments 7/8: a propensity-matched analysis comparing open, laparoscopic, and robotic approach.
Surg Endosc
January 2025
Division of Hepatobiliary Surgery, The First Affiliated Hospital of Guangxi Medical University, Nanning, 530021, Guangxi, China.
Background: Both laparoscopic hepatectomy (LH) and robotic hepatectomy (RH) have been performed for tumors in nearly all liver segments. However, few studies have compared the outcomes of patients who underwent open hepatectomy (OH), LH and RH for the treatment of Barcelona Clinic Liver Cancer (BCLC) stage 0-A HCC in S7/8.
Methods: The clinical data of patients who underwent S7/8 resection for the treatment of BCLC stage 0-A HCC in the First Affiliated Hospital of Guangxi Medical University from July 2017 to July 2023 were retrospectively collected.

Department of Hepatobiliary and Pancreatic Surgery, The Affiliated Cancer Hospital of Zhengzhou University & Henan Cancer Hospital, Zhengzhou, Henan, China (Q.L., J.O., Y.Z., J.Z.). Electronic address:
Rationale And Objectives: The purpose of this study was to demonstrate the impact of postoperative adjuvant transarterial chemoembolization (TACE) on the prognosis of patients with macrotrabecular-massive hepatocellular carcinoma (MTM-HCC).
Materials And Methods: This retrospective study used the clinical records of patients with resected MTM-HCC with/without adjuvant TACE at three centers between January 2015 and December 2022. The primary end point was recurrence free survival (RFS).
Thermal ablation versus surgical resection of small-size colorectal liver metastases (COLLISION): an international, randomised, controlled, phase 3 non-inferiority trial.
Lancet Oncol

Department of Radiology and Nuclear Medicine, Amsterdam UMC location VUmc, Amsterdam, Netherlands. Electronic address:
Background: For patients with small-size colorectal liver metastases, growing evidence suggests thermal ablation to be associated with fewer adverse events and faster recovery than resection while also challenging resection in terms of local control and overall survival. This study assessed the potential non-inferiority of thermal ablation compared with surgical resection in patients with small-size resectable colorectal liver metastases.
Methods: Adult patients (aged ≥18 years) from 14 centres in the Netherlands, Belgium, and Italy with ten or fewer small-size (≤3 cm) colorectal liver metastases, no extrahepatic metastases, and an Eastern Cooperative Oncology Group performance status of 0-2, were stratified per centre, and according to their disease burden, into low, intermediate, and high disease burden subgroups and randomly assigned 1:1 to receive either thermal ablation (experimental group) or surgical resection (control group) of all target colorectal liver metastases using the web-based module Castor electronic data capture with variable block sizes of 4, 6, and 8.
Quantitative Evaluation of 99mTc-Galactosyl Human Serum Albumin SPECT/CT for the Prediction of Posthepatectomy Liver Failure.
Clin Nucl Med
January 2025
From the Department of Radiology.
Purpose: To evaluate the predictive ability of 99mTc-galactosyl human serum albumin SPECT/CT quantitative parameters for posthepatectomy liver failure (PHLF).
Methods: Sixty-eight patients who underwent 99mTc-galactosyl human serum albumin scintigraphy as a preoperative examination for hepatectomy between July 2021 and December 2023 were prospectively evaluated. The patients were divided into PHLF and non-PHLF groups.
Adjuvant Chemotherapy After Resection of Localized Pancreatic Adenocarcinoma Following Preoperative FOLFIRINOX.
JAMA Oncol
January 2025
Amsterdam UMC, location University of Amsterdam, Department of Surgery, Amsterdam, the Netherlands.
Importance: The effect of adjuvant chemotherapy following resection of pancreatic adenocarcinoma after preoperative (m)FOLFIRINOX (combination leucovorin calcium [folinic acid], fluorouracil, irinotecan hydrochloride, and oxaliplatin in full or modified dosing) chemotherapy on overall survival (OS) is unclear because current studies do not account for the number of cycles of preoperative chemotherapy and adjuvant chemotherapy regimen.
Objective: To investigate the association of adjuvant chemotherapy following resection of pancreatic adenocarcinoma after preoperative (m)FOLFIRINOX with OS, taking into account the number of cycles of preoperative chemotherapy and adjuvant chemotherapy regimen.
Design, Setting, And Participants: This retrospective cohort study included patients with localized pancreatic adenocarcinoma treated with 2 to 11 cycles of preoperative (m)FOLFIRINOX followed by resection across 48 centers in 20 countries from 2010 to 2018.
