The sublingual mucosa is a commonly used intraoral location for identifying microcirculatory alterations using handheld vital microscopes (HVMs). The anatomic description of the sublingual cave and its related training have not been adequately introduced. The aim of this study was to introduce anatomy guided sublingual microcirculatory assessment.

Materials And Methods: In a multicenter Phase I/II study, patients with unresectable PHC due to extensive vascular involvement or N2 lymph node metastases or local recurrence after resection for PHC were included and treated by open or percutaneous IRE combined with palliative chemotherapy (current standard of care). The primary outcome was the number of major adverse events occurring within 90 d after IRE (grade ≥3), and the upper limit was predefined at 60%.
Background: In approximately 40% of patients with perihilar cholangiocarcinoma (PHC), the tumor is deemed unresectable at laparotomy, often due to vascular involvement. On imaging, occlusion, narrowing, wall irregularity and >180° tumor-vessel contact have been suggested to predict vascular involvement in patients with PHC. The objective of this study was to correlate computed tomography (CT) findings in PHC with surgical and histopathological results, in order to evaluate the accuracy of currently used CT criteria for vascular involvement.

Methods: All patients with intrahepatic, perihilar, and mid-cholangiocarcinoma presented at Amsterdam UMC between January 2016 and October 2019 were included. The radiologic response after 3 and/or 6 cycles of gem/cis chemotherapy in patients with unresectable locally advanced or borderline resectable disease was derived from the original radiologic reports and subsequently re-evaluated for surgical exploration by consensus reading of 2 HPB surgeons and 1 radiologist.
Background: Standard portal vein resection (PVR) has been proposed to improve oncological outcomes in patients with perihilar cholangiocarcinoma (PHC), however it potentially introduces an increased risk of morbidity. The policy in Amsterdam UMC(AMC) is to resect the portal vein bifurcation selectively when involved, while in Charité-Universitätsmedizin Berlin, standard PVR is performed with right trisectionectomy. The objective of this study was to analyze postoperative outcomes and survival after standard or selective PVR for PHC.

It is unclear whether this caused a shift towards more complicated cases of acute appendicitis. We compared a cohort of patients diagnosed with acute appendicitis during the 2020 COVID-19 pandemic with a 2019 control cohort.

Complications such as bile leakage and liver failure have been suggested to be more common after right-sided resections compared to left-sided resections, whilst superior oncological outcomes have been reported after right-sided resections. However, data on outcomes after right-sided or left-sided liver resections in PHC are scarce.

Despite extensive preoperative imaging, approximately 25% of patients are deemed unresectable at laparotomy due to metastasized disease. The aim of this study was to evaluate the frequency of unresectable disease found at staging laparoscopy and to identify predictors for detecting metastasized intrahepatic cholangiocarcinoma.
View Article and Find Full Text PDFBackground: Preoperative biliary drainage in patients with presumed resectable perihilar cholangiocarcinoma (PHC) is hypothesized to promote the occurrence of seeding metastases. Seeding metastases can occur at the surgical scars or at the site of postoperative drains, and in case of percutaneous biliary drainage, at the catheter port-site. To prevent seeding metastases after resection, we routinely treated PHC patients with preoperative radiotherapy (RT) for over 25 years until January 2018.

The criteria for (un)resectability in cholangiocarcinoma varies between studies and no consensus-based agreement is available about these criteria. By performing a systematic literature review, we aimed to investigate the efficacy and safety of systemic induction therapy in initially unresectable locally advanced perihilar (pCCA) and intrahepatic cholangiocarcinoma (iCCA) and summarize resectability criteria used across studies.

Therefore, CD is considered inferior to a Roux-and-Y hepaticojejunostomy (HJ). The aim of this study was to compare short- and long-term outcomes following CD and HJ for benign biliary diseases.

The objective of this study was to estimate eligibility for LT in a cohort of pCCA patients in two tertiary referral centers.
Methods: Patients diagnosed with pCCA between 2002 and 2014 were included from two tertiary referral centers in the Netherlands.
Background: Hepatopancreatoduodenectomy (HPD) is an aggressive operation for treatment of advanced bile duct and gallbladder cancer associated with high perioperative morbidity and mortality, and uncertain oncological benefit in terms of survival. Few reports on HPD from Western centers exist. The purpose of this study was to evaluate safety and efficacy for HPD in European centers.
View Article and Find Full Text PDFBackground: Outcomes for the four anatomical subtypes of biliary tract carcinoma (BTC) - intrahepatic, perihilar and distal cholangiocarcinoma (ICC, PHCC, DCC) and gallbladder carcinoma (GBC) - are often combined. However, large cohorts comparing short- and long-term outcomes for the anatomical subtypes of BTC are lacking.
Methods: All patients who underwent resection for pathology proven ICC, PHCC, DCC or GBC (2000-2016) from a single Western high-volume center were retrospectively selected.
In perihilar cholangiocarcinoma (PHC), interpretation of the resection specimen is challenging for pathologists and clinicians alike. Thorough and correct reporting is necessary for reliable interpretation of residual disease status. The aim of this study is to assess completeness of PHC pathology reports in a single center and assess what hampers interpretation of pathology reports by clinicians.

However, reported postoperative outcomes vary, with notable differences between Western and Asian series. We aimed to determine morbidity and mortality rates after major hepatectomy in patients with perihilar cholangiocarcinoma and assess differences in outcome regarding geographic location and hospital volume.

Intracardiac obstruction to this pathway causing systemic outflow tract obstruction (SOTO) may be present at birth or develop over time. Long-term survival after Fontan has not been defined.

However, FamHis provides information on individual risk. Coronary artery calcification score (CACS) is a metric of atherosclerosis that may determine the individual risk within families at high risk of premature CAD.
