Objective: Stereotactic body radiation therapy (SBRT) is a therapeutic option in the guidelines for liver primaries after standard strategies like surgery or thermoablation have failed. To assess its efficacy and safety, we reviewed all patients treated by SBRT for a hepatocellular carcinoma (HCC) over a six-year period.
Methods And Materials: The study included all patients treated by SBRT for HCC between April 2015 and November 2021 in the University Cancer Institute at Toulouse-Oncopole.
Background: About 20% of patients with acute pancreatitis develop a necrotising form with a worse prognosis due to frequent appearance of organ failure(s) and/or infection of necrosis. Aims of the present study was to evaluate the "step up" approach treatment of infected necrosis in terms of: feasibility, success in resolving infection, morbidity of procedures, risk factors associated with death and long-term sequels.
Methods: In this observational retrospective monocentric study in the real life, necrotizing acute pancreatitis at the stage of infected walled-off necrosis were treated as follow: first step with drainage (radiologic and/or endoscopic-ultrasound-guided with lumen apposing metal stent); in case of failure, minimally invasive necrosectomy sessions(s) by endoscopy through the stent and/or via retroperitoneal surgery (step 2); If necessary open surgery as a third step.
Background: In case of locally advanced and/or non-metastatic unresectable esophageal cancer, definitive chemoradiotherapy (CRT) delivering 50 Gy in 25 daily fractions in combination with platinum-based regimen remains the standard of care resulting in a 2-year disease-free survival of 25% which deserves to be associated with new systemic strategies. In recent years, several immune checkpoint inhibitors (anti-PD1/anti-PD-L1, anti-Program-Death 1/anti-Program-Death ligand 1) have been approved for the treatment of various solid malignancies including metastatic esophageal cancer. As such, we hypothesized that the addition of an anti-PD-L1 to CRT would provide clinical benefit for patients with locally advanced oesophageal cancer.

Methods: Overall chest HRCT, lung function and skin score changes were evaluated in 33 consecutive diffuse SSc patients before and after aHSCT during yearly routine follow-up visits between January 2000 and September 2016. Two independent radiologists blindly assessed the ILD extent using semi-quantitative Goh and Wells method, the widest oesophageal diameter (WOD) and the oesophageal volume (OV) on HRCT.
Background: Accurate prediction of portal hypertension recurrence after transjugular intrahepatic portosystemic shunt (TIPS) placement will improve clinical decision-making.
Purpose: To evaluate if perioperative variables could predict disease-free survival (DFS) in cirrhotic patients with portal hypertension (PHT) treated with TIPS.
Materials And Methods: We recruited 206 cirrhotic patients with PHT treated with TIPS, randomly assigned to training (n = 138) and validation (n = 68) sets.
Resection of enlarged cardiophrenic lymph nodes (CPLN) is a procedure required to obtain complete cytoreduction in selected patients affected by advanced ovarian cancer. Their resection by transdiaphragmatic approach has been demonstrated to be feasible with low rates of morbidity. The main complications associated with this procedure are pleural effusion, pneumothorax, and rarely, chylothorax.

Material And Methods: A cohort of 353 MSs from 2015 to 2018 was prospectively evaluated. MSs were assigned to four groups (high, high-intermediate, low-intermediate, and low achievers) based on their results to a 20-MCQs performance evaluation referred to as the pretest.
Purpose: The clinical adoption of quantitative imaging biomarkers (radiomics) has established the need for high quality contrast-enhancement in medical images. We aimed to develop a machine-learning algorithm for Quality Control of Contrast-Enhancement on CT-scan (CECT-QC).
Method: Multicenter data from four independent cohorts [A, B, C, D] of patients with measurable liver lesions were analyzed retrospectively (patients:time-points; 503:3397): [A] dynamic CTs from primary liver cancer (60:2359); [B] triphasic CTs from primary liver cancer (31:93); [C] triphasic CTs from hepatocellular carcinoma (121:363); [D] portal venous phase CTs of liver metastasis from colorectal cancer (291:582).
The majority of gastroenteropancreatic (GEP) neuroendocrine tumors (NETs) are diagnosed at a non-resectable stage due to non-specific clinical syndromes, late manifestations from mass effects, or incidental detection of a clinically silent disease. Management strategies include curative or cytoreduction surgery, imaging-guided intervention, chemotherapy, immunotherapy, and radionuclide therapies. In this step-by-step review, we provide a structured approach for standardized reading and reporting of medical imaging studies covering content and terminology.

Material And Methods: We retrospectively analyzed 178 cirrhotic patients from 27 institutions, with biopsy-proven liver nodules classified as indeterminate using the European Association for the Study of the Liver (EASL) guidelines. Patients were randomly assigned to a discovery cohort (142 patients (pts.
Imaging-guided interventions or interventional radiology (IR) are intended to improve the efficiency and accuracy of the medical procedure regardless of the organ, as well as the safety and comfort of the patient. Currently IR concerns all medico-surgical specialties with a number of acts constantly increasing, and is today a major field of innovation that responds to a strong societal demand to move towards more and more effective treatments, but also less and less invasive. The ambulatory shift in IR is a major prospect of saving and improving the quality of care.

Therefore, the development of noninvasive techniques to detect PHT is crucial for prognosis and treatment.
Aim: The aim of our study was to assess the diagnostic performance of a new spleno-hepatic index (SHI) measured from equilibrium radionuclide ventriculography (ERV) images in detecting patients with cirrhotic PHT.
Background: Abdominal interventions are usually contraindicated in patients with cirrhosis and portal hypertension because of increased morbidity and mortality. Decreasing portal pressure with transjugular intrahepatic portosystemic shunt (TIPS) may improve patient outcomes. We report our experience with patients treated by neoadjuvant TIPS to identify those who would most benefit from this two-step procedure.

Interventional radiology plays a major role in the modern management of liver cancers, in primary hepatic malignancies or metastases and in palliative or curative situations. Radiological treatments are divided in two categories based on their approach: endovascular treatment and direct transcapsular access. Endovascular treatments include mainly three applications: transarterial chemoembolization (TACE), transarterial radioembolization (TARE) and portal vein embolization (PVE).

Methods: Cohort study based on data from a multidisciplinary team meeting (MDT) dedicated to HCC. From 2006 to 2013, we included every patient with newly diagnosed HCC, for whom curative treatment (liver transplantation (LT), radiofrequency ablation (RFA), surgical resection (SR)) was decided upon.
Background & Aims: There is controversy over the ability of transjugular intrahepatic portosystemic shunts (TIPS) to increase survival times of patients with cirrhosis and refractory ascites. The high rate of shunt dysfunction with the use of uncovered stents counteracts the benefits of TIPS. We performed a randomized controlled trial to determine the effects of TIPS with stents covered with polytetrafluoroethylene in these patients.
View Article and Find Full Text PDFBackground: The protein concentration in ascites is usually low in cirrhosis because capillarization and defenestration of the sinusoids limit diffusion of large proteins from plasma to the space of Disse. However, some cirrhotic patients have high-protein ascites (HPA).
Aim: The aim of this study was to describe and compare the characteristics and prognosis between cirrhotic patients with HPA (>20 g/l) and patients with low-protein ascites (LPA).
Background And Objectives: The predictors of long-term renal function in living kidney donors are currently discussed. Our objectives were to describe the predictors of functional gain of the remaining kidney after kidney donation. We hypothesized that GFR of the remaining kidney divided by volume of this kidney (rk-GFR/vol) would reflect the density of functional nephrons and be inversely associated with functional gain of the remaining kidney.
