Randomized clinical trial comparing liver resection with and without perioperative assessment of liver function

2018

Background Liver function tests may help to predict outcomes after liver surgery. The aim of this study was to evaluate the clinical impact on postoperative outcome and patient management of perioperative liver function testing using the LiMAx® test. Methods A multicentre RCT was conducted in six academic liver centres. Patients with intrahepatic tumours scheduled for open liver resection of at least one segment were eligible. Patients were randomized to undergo additional perioperative liver function tests (LiMAx® group) or standard care (control group). Patients in the intervention arm received two perioperative LiMAx® tests, one before the operation for surgical planning and another afte…

Stump appendicitis. A case report

2016

Highlights • Stump appendicitis (SA) is a rare, but noteworthy, diagnosis that warrants early detection. • Delay in the diagnosis of SA may result in serious complications like stump gangrene, perforation and peritonitis. • More research is needed to identify strategies to prevent SA. • We underline the emergent role of lower endoscopy to clarify diagnosis resolve the symptoms. • Surgeons need to have a heightened awareness of the possibility of SA.

Whole-body MRI, FDG-PET/CT, and bone marrow biopsy, for the assessment of bone marrow involvement in patients with newly diagnosed lymphoma

2016

Purpose To compare whole-body MRI (WB-MRI) with diffusion-weighted imaging (DWI), FDG-PET/CT, and bone marrow biopsy (BMB), for the evaluation of bone marrow involvement (BMI) in patients with newly diagnosed lymphoma. Materials and Methods This retrospective study was approved by our Institutional Review Board. Two independent radiologists and one nuclear medicine specialist reviewed all WB-MRI and FDG-PET/CT scans prospectively performed on 104 patients with newly diagnosed lymphoma (53 males; 47 Hodgkin; mean age: 44 years; range, 15–86 years) between 2013 and 2015. The delay between imaging scans and BMBs was up to 10 days. The diagnostic accuracy of WB-MRI (1.5 Tesla MR scanner, with T…

Peut-on proposer un prélèvement du ganglion sentinelle en cas de chimiothérapie néoadjuvante dans les cancers du sein et à quel moment ?

2016

The main goal of preoperative chemotherapy is to reduce the size of the tumor and allow conservative treatment. Neoadjuvant treatment can affect axillary status with a downstaging in one third of the cases. For these patients, the benefit of axillary node dissection is questioned and the sentinel node biopsy (SLNB) seems to be a relevant option. However, the timing of performing SLNB is still debated especially for clinical negative patients with negative axillary ultrasound before preoperative chemotherapy. For axillary positive nodes proved by biopsy/cytology before preoperative chemotherapy, SLNB can be an option if there is a good clinical and radiological response.

Quantitative Musculoskeletal Ultrasound

2020

AbstractUltrasound (US) imaging plays a crucial role in the assessment of musculoskeletal (MSK) disorders. Several quantitative tools are offered by US systems and add information to conventional US imaging. This article reviews the quantitative US imaging tools currently available in MSK radiology, specifically focusing on the evaluation of elasticity with shear-wave elastography, perfusion with contrast-enhanced US and noncontrast superb microvascular imaging, and bone and muscle mass with quantitative US methods. Some of them are well established and already of clinical value, such as elasticity and contrast-enhanced perfusion assessment in muscles and tendons. MSK radiologists should be…

Can Early Postoperative O-(2-18FFluoroethyl)-l-Tyrosine Positron Emission Tomography After Resection of Glioblastoma Predict the Location of Later Tu…

2019

Objective Glioblastoma inevitably recurs despite aggressive therapy. Therefore, it would be helpful to predict the location of tumor recurrence from postoperative imaging to customize further treatment. O-(2-18Ffluoroethyl)- l -tyrosine (FET) positron emission tomography (PET) might be a helpful technique, because tumor tissue can be differentiated from normal brain tissue with high specificity. Methods Thirty-two consecutive patients with perioperative and follow-up imaging data available were included. On postoperative FET-PET, the tumor/normal brain (TTB) ratio around the resection cavity borders was measured. Increased TTB ratios were recorded and anatomically correlated with the site o…

Chylous ascites after lymphadenectomy for gynecological malignancies

2016

Background and Objectives Chylous ascites, an accumulation of milky-white lymph fluid in the peritoneal cavity, is a rare complication following retroperitoneal lymphadenectomy. This study evaluated the appearance and management of chylous ascites following lymphadenectomy for gynecological malignancies. Methods A total of 931 patients who underwent lymphadenectomy for gynecological malignancies at Erlangen University Hospital between 2002 and 2013 were reviewed retrospectively. Results Chylous ascites occurred postoperatively in 28 of the 931 patients (3.0%). All patients with chylous ascites had undergone combined systematic para-aortic and pelvic lymphadenectomy (SAPL). Patients with chy…

Direct oral anticoagulants for the treatment of pulmonary embolism in patients with renal impairment.

2021

Pulmonary embolism (PE) is associated with adverse outcomes and substantial morbidity and mortality. Patients with PE often have renal impairment because of shared risk factors and close links between the renal and cardiovascular systems. Furthermore, patients with PE and renal impairment are at increased risk of recurrent thrombosis. Therefore, anticoagulation is crucial to treat the acute event, prevent recurrent venous thromboembolism (VTE), and optimize patient outcomes. However, when treated with an anticoagulant, patients with renal impairment also have an elevated risk of bleeding. Direct oral anticoagulants (DOACs) are the first-choice treatment for acute VTE in eligible patients. H…
