Biliary ascariasis and hepatic ascariasis

Biliary ascariasis and hepatic ascariasis are two diseases that are closely related yet distinct from each other, both originating from intestinal roundworms. In 1932, the British doctor Mure performed the first choledochotomy for roundworm extraction in China, and in 1942, West China Medical University performed the second choledochotomy for roundworm extraction, thus opening a new chapter in Eastern biliary surgery. According to records since the discovery of biliary ascariasis, this disease has plagued China for at least half a century and has become an important cause of primary hepatolithiasis. It was not until the late 1970s that, with the continuous improvement of people's living standards and the gradual improvement of sanitary conditions, the incidence of biliary ascariasis began to show a significant downward trend.
