“…Available literature suggests that in presumably healthy individuals, the upper limit of extrahepatic, right hepatic and the left hepatic bile duct is 6.0, 3.8 and 3.0 mm, respectively34,35 . We have adhered to these width limits in the present study and believe that a positive MRC examination indicates pathological bile ducts.…”

Prevalence of Sclerosing Cholangitis Detected by Magnetic Resonance Cholangiography in Patients With Long-term Inflammatory Bowel Disease

Using MRC analysis of patients with long-term IBD, we found the prevalence of PSC to be around 3-fold higher than that detected based on symptoms. Sixty-five percent of patients had subclinical PSC associated with progressive IBD, with no biochemical abnormalities and mild disease, based on radiology findings. PSC appears to progress in patients with subclinical disease, but long-term outcomes are not known.

“…Hence, the approach in this research can be considered as the first one that uses DnCNN to remove noise from bile duct MR images. [32] introduced a fruitful study about processing the Magnetic Resonance cholangiopancreatography (MRCP) images to measure the bile duct diameter. The authors in [33] followed an approach to check the efficiency of the DnCNN by introducing some artificial noise to be corrected, and in the results, they obtained very small variations.…”

A set of tubes known as bile ducts connects the liver to an organ below it directly that is called Gallbladder. The dilation of a bile duct is an important indicator regarding any serious issue in the human body. Number of reasons may cause bile duct dilation, such as: stones, tumors which commonly occur due to pancreas or papilla of vater. In this paper, the main contributions are: 1) a novel framework that consists of three phases to be applied on a set of Magnetic Resonance Imaging (MRI) images 2) an extracted set of features with their accurate values that express the condition of the biliary trees from the MRI images. Such dataset can be used in several applications to determine whether a bile duct is dilated or not. The dataset is organized as the following: half of the MRI images are for normal bile ducts, while the other half is for dilated bile ducts. To extract the useful features to diagnose the medical condition of the bile ducts from the MRI images, we implemented and applied the proposed framework that is started by using the enhanced active contour technique without edges in combination with Denoising Convolutional Neural Networks (DnCNN) to perform the segmentation and features extraction process. After that, the output of the segmentation process is the segmented biliary tree that will be used later to extract the needful features to make a diagnostic decision whether there is a dilation or not by comparing the features values of the normal versus the dilated bile ducts. We applied the feed forward neural network with backpropagation training algorithm for classification purposes. According to the experiments, the overall accuracy of the proposed framework was 90.00%. Such approach improves and increases the accuracy of the physicians’ diagnostic decisions which is considered as of significant importance for treatment and cure.

“…A CBD greater then 6mm, is classified as dilated and increases likelihood of CBD stones (EASL, 2016), estimated to be present in 10-20% of symptomatic individuals (Williams et al, 2017). Factors such as age, previous cholecystectomy and BMI all significantly affect the diameter of the CBD (Peng et al 2015) therefore, individualistic interpretation is required. In this case, with stated factors considered and in combination with liver function test (LFT) derangement there was high probability of the presence of CBD stones.…”

The gallbladder stores bile from the liver and releases it into the duodenum. Imbalance in bile components (typically, cholesterol) can lead to cholelithiasis, the crystallisation of choleliths (gallstones). Cholelithiasis is common, affecting a fifth of people in Western countries. The stones can become lodged in the biliary duct and obstruct bile flow. Bile obstruction affects levels of bilirubin, causing cholestatic jaundice. Associated symptoms include nausea, dark urine and pale stools. Gallstones can also cause cholecystitis, the inflammation of the gallbladder. They also often cause pain (biliary colic), especially sudden-onset, episodic, radiating right hypochondrial pain, and biliary pathology is the main cause of upper abdominal pain. Diagnosing these presentations requires a multispectral, holistic assessment comprising numerous investigations, including clinical history, liver function tests, Murphy's sign and abdominal ultrasound. Treatment is usually gallbladder removal surgery (laparoscopic cholecystectomy), with either bile duct exploration or endoscopic retrograde cholangio-pancreatography (ERCP). Good nurse–patient communication is essential to ensure quality of care. The case study presented here covers the assessment and biliary diagnosis of a female patient presenting with severe right hypochondrial pain. The review of existing evidence and the case study should help hepatobiliary nurses deliver quality care for patients presenting with symptoms of gallstones.

Common bile duct diameter in an asymptomatic population: A magnetic resonance imaging study

Abstract: We established a reference range for the CBD diameter on MRCP for an asymptomatic population. The CBD diameter is correlated with age. Respiration did not affect the non-dilated CBD diameter.
