The world's first publication of a comparative study on the usefulness of 'Biliary Endoscopy'
Oct 14, 2024
Professor Moon Jong-ho's team at Soonchunhyang University Bucheon Hospital's Gastroenterology Center (Professor Lee Yoon-na, Shin Il-sang) published the world's first comparative study on the usefulness of biliary endoscopy for the effective diagnosis of difficult-to-diagnose biliary tract tumors, and the study was published in the European Gastrointestinal Endoscopy Society in recognition of its high academic value.
The biliary tract is an organ that serves to transport bile from the liver to the duodenum to help digestion. The biliary tract is very thin and deep in our body, so it is often difficult to accurately diagnose tumors that occur in the biliary tract.
Biliary endoscopy, which directly observes the inside of the bile duct, is a useful test for diagnosis and treatment of various biliary tract diseases by inserting a special endoscope with a diameter into the biliary tract. Early reported biliary endoscopy was developed as a cap endoscopy system in which the duodenoscope became 'motherscope' and the biliary endoscope 'bibyscope', but there was a limit to clinical usefulness because two endoscopy systems had to be performed by two doctors.
Since then, through many technological advances, two types of biliary endoscopy methods are currently being used: digital biliary endoscopy named 'SpyGlass' and direct oral biliary endoscopy in which micrographs are inserted directly into the biliary tract. However, there have been no specific comparative studies on the two biliary endoscopy methods worldwide.
In response, Professor Moon Jong-ho's team compared the technical success rate of biliary endoscopy, detection rate of abnormal lesions in the biliary tract, visualization quality, histocompatibility, and complications based on the test results of 38 patients who performed both biliary endoscopy from 2020 to 2022.
As a result, direct oral biliary endoscopy showed superior results compared to digital biliary endoscopy in terms of detection rate and visualization quality of abnormal lesions in the biliary tract, and in particular, it was confirmed that the surface structure and microvascular pattern of abnormal lesions can be observed in more detail. Conversely, it was confirmed that digital biliary endoscopy has a higher technical success rate and shorter procedure time than micrograph biliary endoscopy, so it can be more useful in the convenience and safety of the test.
By comparing the differences between the two biliary endoscopy methods for the first time in the world, the results of this study suggested the direction of technological development of the biliary endoscopy system in the future, and were published in the October issue of the European Society of Gastrointestinal Endoscopy (IF: 11.5)', one of the most prestigious journals in the field of gastrointestinal endoscopy in recognition of its high academic value.
Professor Moon Jong-ho, director of the study, explained that "This study is a very meaningful study that presents a future blueprint for more accurate and effective biliary endoscopy by comparing differences in biliary endoscopy for differential diagnosis of difficult-to-diagnose biliary tract tumors for the first time in the world." We hope that there will be more cases where early diagnosis and treatment of biliary tract tumors with poor prognosis will be possible through continuous development of biliary endoscopy technology in the future.
