Bronchobiliary fistula in a patient with liver cancer

Hepatobiliary & Pancreatic Diseases International 2024年第5期23卷 523-525页

作者： Yao-Xin Chen zhi-Hua Deng Hao Zhao Bi-Ying Zhou Jing-Jing Guo Gang Zeng Jin-xian Qian Department of Respiratory and Critical Care Medicine Suzhou Municipal Hospital Affiliated to Nanjing Medical UniversitySuzhou 215000China

Bronchobiliary fistula(BBF) is a pathologic channel between the biliary tract and bronchial tree. In general, congenital BBF is relatively rare in adult patients. There are a few case reports suggesting that BBF is mainly secondary to hepatobiliary diseases, such as biliary obstruction, tumor, surgery, or liver abscess, and liver tumor is the predominant causative factor [1]. In addition, with the increasing number of liver and biliary surgeries and interventional therapies in recent years, more cases of BBF were reported as a postoperative complication [ 2, 3 ]. In this case, we presented a patient who underwent interventional treatment for liver tumor and was treated for his respiratory symptoms but diagnosed with BBF finally. Here, we summarized the clinical features and main diagnostic procedures of the case, aiming to provide evidence for early identification and diagnosis of BBF.

Multiple waves of coronavirus disease 2019(COVID-19) outbreaks have affected numerous countries worldwide. The first case of SARS-CoV-2 reinfection was reported in Hong Kong in August 2020^([1]), leading to increased interest in the effectiveness of natural immunity acquired from primary infection. While data reports vary across countries, all findings indicate that prior SARS-CoV-2 infection provides substantial protection against reinfection^([2]). However, natural immunity from infection with previous non-Omicron or early Omicron sub-lineages offers lower levels of protection against Omicron reinfection, with rates below 60%^([3]) and approximately 75%[4], respectively.
