Implanting a biliary stent into a stenosis or obstruction is a better way to treat biliary obstruction. In complex biliary reconstruction, the application of biliary stents still cannot be ignored, especially when the biliary tract reconstruction is not satisfactory, the indwelling of biliary stents should be considered.

Dr. Charters J. Symonds was the first person to document the placement of a rigid esophageal catheter used to relieve malignant esophageal strictures. Since then, stents have been used to relieve almost all malignant tumors in the gastrointestinal tract.
