Improving Safety in Living Liver Donation: Lessons From Intraoperative Adverse Events in 438 Donors Undergoing a Left Liver Resection.

Background: Donor safety is paramount in living organ donation. Left liver resections are considered safer than right lobe hepatectomies. However, unexpected intraoperative adverse events (iAEs), defined as any deviation from the ideal intraoperative course, can also occur during left liver resections and may be life threatening or lead to postoperative complication or permanent harm to the donor and recipient.

Proposal of early CT morphological criteria for response of liver metastases to systemic treatments in gastroenteropancreatic neuroendocrine tumors: Alternatives to RECIST.

RECIST 1.1 criteria are commonly used with computed tomography (CT) to evaluate the efficacy of systemic treatments in patients with neuroendocrine tumors (NETs) and liver metastases (LMs), but their relevance is questioned in this setting. We aimed to explore alternative criteria using different numbers of measured LMs and thresholds of size and density variation.

Development of a New Index to Assess Small Bowel Inflammation Severity in Crohn's Disease Using Magnetic Resonance Enterography.

Background: The severity of small bowel (SB) inflammation in Crohn's disease (CD) patients is a key component of the therapeutic choice. We aimed to develop a SB-CD Magnetic Resonance Enterography (MRE) index of Inflammation Severity (CDMRIS).

Methods: Each gastroenterologist/radiologist pair in 13 centers selected MREs from 6 patients with SB-CD stratified on their perceived MRE inflammation severity.

Intrahepatic Portal Vein Aneurysm: A Case Report of an Uncanny Late Complication of Liver Transplantation.

Background: Whereas chronic rejection, opportunistic infections, post-transplant lymphoproliferative disorder, hemophagocytic lymphohistiocytosis, biliary tract issues, and cardiovascular side effects of immunosuppressive drugs are frequently reported as late complications in liver transplanted patients, intrahepatic portal venous aneurysm following liver transplantation remains exceptional and unusual.

Case Report: We report the case of a 25-year-old man who underwent a liver transplantation in 1997 because he had glycogen storage disease type 4. The patient developed a late postoperative complication, an intrahepatic portal aneurysm, and 2 episodes of acute cholangitis.

Limited Performance of Estimated Total Kidney Volume for Follow-up of ADPKD.

Introduction: Total kidney volume (TKV) is a qualified biomarker for disease progression in autosomal dominant polycystic kidney disease (ADPKD). Recent studies suggest that TKV estimated using ellipsoid formula correlates well with TKV measured by manual planimetry (gold standard). We investigated whether the ellipsoid formula could replace manual planimetry for follow-up of ADPKD patients.

Prediction of tumor response and patient outcome after radioembolization of hepatocellular carcinoma using 90Y-PET-computed tomography dosimetry.

Aim: 90Y-radioembolization using glass or resin microspheres is increasingly used for the treatment of hepatocellular carcinoma (HCC). The aim of this retrospective study is to determine the prognostic relevance of dosimetric parameters defined with 90Y-PET-CT obtained immediately after radioembolization.

Methods: Forty-five HCC patients, mostly with multiple lesions, were treated by radioembolization between 2011 and 2017.

Mucin-producing hepatic cystic neoplasms: an uncommon but challenging disease often misdiagnosed and mismanaged.

Mucin-producing hepatic cystic neoplasms (MHCN) are uncommon and potentially malignant. Nine MHCN were encountered in our centre for over 32 years. Patients' clinical, biological, radiological and pathological features were reviewed.

Prospective comparison of a fast 1.5-T biparametric with the 3.0-T multiparametric ESUR magnetic resonance imaging protocol as a triage test for men at risk of prostate cancer.

Objective: To compare prospectively the diagnostic performance of a biparametric (T2-weighted imaging [T2WI] and diffusion-weighted imaging [DWI]) 1.5-T fast magnetic resonance imaging (fMRI) protocol with the standard 3.0-T multiparametric MRI (mpMRI) protocol of the European Society of Urological Imaging (ESUR) in men referred for a prostate biopsy.

Impact of Intraoperative Pancreatoscopy with Intraductal Biopsies on Surgical Management of Intraductal Papillary Mucinous Neoplasm of the Pancreas.

Background: Because of its known malignant potential, precise histologic diagnosis of intraductal papillary mucinous neoplasm of the pancreas (IPMN) during intraoperative pancreatoscopy (IOP) is essential for complete surgical resection. The impact of IOP on perioperative IPMN patient management was reviewed over 20 years of practice at Cliniques universitaires Saint-Luc, Brussels, Belgium.

Study Design: Among 86 IPMN patients treated by pancreatectomy between 1991 and 2013, 21 patients had a dilated main pancreatic duct enabling IOP and were retrospectively reviewed.

Unilateral adrenal hemorrhagic infarction in essential thrombocythemia.

Adrenal hemorrhage is a rare disease associated with various conditions. We report a case of a 68-year-old woman with abdominal and back pain. The diagnostic work-up showed a left adrenal gland infarction associated with essential thrombocythemia.

Mesenteric inflammatory myofibroblastic tumor: MRI and CT imaging correlated to anatomical pathology.

Inflammatory myofibroblastic tumor (IMT) is a rare tumor, classified by WHO of intermediate biological potential with tendency for local recurrence and small risk for distant metastasis. Histologically IMT is a mixture of inflamma- tory cells and myofibroblastic spindle cells proliferation. To our knowledge there is no MRI description of mesenteric IMT in the literature.

Living Donor Liver Transplantation in Children: Surgical and Immunological Results in 250 Recipients at Université Catholique de Louvain.

Objectives: To evaluate the outcome of pediatric living donor liver transplantation (LDLT) regarding portal vein (PV) reconstruction, ABO compatibility, and impact of maternal donation on graft acceptance.

Background: LDLT and ABO-mismatched transplantation constitute feasible options to alleviate organ shortage in children. Vascular complications of portal hypoplasia in biliary atresia (BA) and acute rejection (AR) are still major concerns in this field.

Hepatocellular adenoma management: call for shared guidelines and multidisciplinary approach.

Hepatocellular adenomas are rare benign nodules developed mainly in women taking oral contraceptives. They are solitary or multiple. Their size is highly variable.

One-step TNM staging of high-risk prostate cancer using magnetic resonance imaging (MRI): toward an upfront simplified "all-in-one" imaging approach?

Background: Multiparametric magnetic resonance imaging (mpMRI) is the standard for local prostate cancer (PCa) staging. Whole-body MRI (wbMRI) has shown capabilities for metastatic screening. This study assesses the feasibility and value of an all-in-one AJCC TNM staging of PCa during a unique MRI session combining mpMRI and wbMRI.

Histological and immunohistochemical revision of hepatocellular adenomas: a learning experience.

Light has been shed on the genotype/phenotype correlation in hepatocellular adenoma (HCA) recognizing HNF1 α -inactivated HCA (H-HCA), inflammatory HCA (IHCA), and β -catenin-activated HCA (b-HCA). We reviewed retrospectively our surgical HCA series to learn how to recognize the different subtypes histopathologically and how to interpret adequately their immunohistochemical staining. From January 1992 to January 2012, 37 patients underwent surgical resection for HCA in our institution.

Diagnosis of cyst infection in patients with autosomal dominant polycystic kidney disease: attributes and limitations of the current modalities.

Cyst infection is a diagnostic challenge in patients with autosomal dominant polycystic kidney disease (ADPKD) because of the lack of specific manifestations and limitations of conventional imaging procedures. Still, recent clinical observations and series have highlighted common criteria for this condition. Cyst infection is diagnosed if confirmed by cyst fluid analysis showing bacteria and neutrophils, and as a probable diagnosis if all four of the following criteria are concomitantly met: temperature of >38°C for >3 days, loin or liver tenderness, C-reactive protein plasma level of >5 mg/dL and no evidence for intracystic bleeding on computed tomography (CT).

Inflammatory myofibroblastic tumor of the pancreatic head.

Inflammatory myofibroblastic tumors are rare, especially in the pancreas. It is sometimes difficult to obtain a definitive diagnosis with radiological imaging and there is not yet consensus about treatment. We report a case of a 56-year-old man with recurrent abdominal pain particularly in the right upper quadrant without other symptoms.

Celiac artery occlusive disease: a rare but potentially critical condition in patients undergoing pancreaticoduodenectomy.

Background/aims: Undiagnosed occlusive disease of celiac trunk and/or superior mesenteric artery may lead to life-threatening complications after pancreatoduodenectomy.

Methodology: Retrospective analysis of a consecutive series of 171 patients scheduled for pancreatico- duodenectomy or total pancreatectomy.

Results: The prevalence of arterial occlusive disease was 5.
