MRCP as an ERCP Alternative
MRCP, also known as magnetic retrograde cholangio-pancreatography, has become an alternative to ERCP procedures. First brought into usage in 1991, MRCP uses magnetic resonance imaging in order to produce a visual image of the bile ducts and pancreatic ducts. It can serve as a noninvasive way to check for gallstones, which may become lodged in the ducts which are adjacent to the gallbladder.
Sometimes it is necessary for patients to consume a contrast material prior to use of an MRCP. This contrast material will help to produce a clearer image of the organs which the MRCP focuses on. It may also be necessary for you to abstain from eating food for several hours prior to undergoing an MRCP. Additionally, if you suffer from a kidney disease it may be inadvisable for you to consume a contrast material in advance of an MRCP. Therefore, a MRCP might not be the best option for you in the event that you have a kidney disease. Similarly, those with electronic and metallic implants may not be well-suited for undergoing an MRCP.
Endoscopic Ultrasound as an ERCP Alternative
Similar to ERCP, endoscopic ultrasound involves insertion of a probe into the body. However, endoscopic ultrasound uses vibrations in order to create an image. These vibrations fall into the ultrasonic register, which is above the range of human hearing.
Although you may be familiar with ultrasound taking place outside of the body, endoscopic ultrasound can allow for a more refined and detailed imaging process. This is because the endoscopic probe is often capable of getting closer to organs than would be otherwise possible using ultrasound externally. Additionally, endoscopic ultrasound shows promise as a tool for breaking up gallstones and mitigating the discomfort which they cause sufferers.
Weighing ERCP Options
Although ERCP and its alternatives need to be weighed on a case-by-case basis, it’s important to be aware of your options prior to undergoing a medical procedure. If you have any questions about these alternatives, or the safety of ERCP, consult our other blog entries but also your physician.
