The risk and predictors of gallbladder cancer in patients with gallbladder polyps: A retrospective cohort study with an insight into confounding by indication.

Background And Aim: We aimed to determine the risk and predictors of gallbladder cancer in all individuals with gallbladder polyps (GP) including those who did not have cholecystectomy.

Methods: The STROCSS guideline was followed to conduct a retrospective cohort study. All individuals with GP between 2010 and 2019 were followed up to determine the risk and predictors of gallbladder cancer.

Partial ALPPS with a longer wait between procedures is safe and yields adequate future liver remnant hypertrophy.

Backgrounds/aims: Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) has generated controversy due to high morbidity and mortality. We present our series of patients with 30-40% parenchymal transection and minimal hilar dissection.

Methods: Patients who had partial ALPPS between April 2015 and April 2016 were included.

Acute Abdomen in the Emergency Department: Is CT a Time-Limiting Factor?

Objective: The purpose of this study was to quantify and integrate key emergency department (ED) and radiology department workflow time intervals within the ED length of stay (LOS) for patients presenting with acute abdomen who require CT.

Materials And Methods: An 11-month retrospective review was performed of all patients presenting to the ED with an acute abdomen who required abdominal CT. Nine key time points associated with ED LOS and CT workflow were collected: triage, physician assessment, CT request, porter schedule, CT start, CT complete, provision of first CT report, ED disposition decision, and physical discharge.

Inter- and intra-operator reliability and repeatability of shear wave elastography in the liver: a study in healthy volunteers.

This study assessed the reproducibility of shear wave elastography (SWE) in the liver of healthy volunteers. Intra- and inter-operator reliability and repeatability were quantified in three different liver segments in a sample of 15 subjects, scanned during four independent sessions (two scans on day 1, two scans 1 wk later) by two operators. A total of 1440 measurements were made.

Episiotomy endometrioma masquerading as peri-anal sepsis: surgeons beware!

A 34-year-old woman with peri-anal pain and swelling was operated in the emergency setting assuming a diagnosis of a perianal abscess. No pus was revealed. Later magnetic resonance imaging (MRI) suggested induration and a mass effect in the peri-anal region.

Tissue-specific differences in 2-fluoro-2-deoxyglucose metabolism beyond FDG-6-P: a 19F NMR spectroscopy study in the rat.

2-Fluoro-[(18)F]-2-deoxy-glucose (FDG) is a positron-emitting analogue of glucose used clinically in positron emission tomography (PET) to assess glucose utilization in diseased and healthy tissue. Originally developed to measure local cerebral glucose utilization rates, it has now found applications in tumour diagnosis and in the study of myocardial glucose uptake. Once taken up into the cell, FDG is phosphorylated to FDG-6-phosphate (FDG-6-P) by hexokinase and was originally believed to be trapped as a terminal metabolite.
