Obstructive jaundice caused by diseases such as hepatobiliary and pancreatic is very common in clinical practice. Obstruction is divided into benign obstruction and malignant obstruction. The common causes of benign obstruction include common bile duct stones, bile duct injury, biliary fistula, papillary stenosis, etc.; the common causes of malignant obstruction include bile duct cancer, pot belly cancer, pancreatic cancer, liver cancer, gallbladder cancer, etc. Endoscopic bile duct stenting for the treatment of benign and malignant obstructive jaundice of biliopancreatic has definite efficacy in relieving obstruction, restoring bile drainage and improving general condition, and has been widely used in clinical practice at home and abroad. For benign obstruction, bile duct stenting is a less damaging drainage modality with low complications, good results, less patient discomfort and no loss of bile. If the bile duct stones are too large and too many and cannot be removed or the stone retrieval fails or if the systemic condition is poor, internal drainage with bile duct plastic stents should be considered for temporary relief of symptoms, and then incision and stone retrieval or surgery can be performed after the condition is stable. For malignant obstructive jaundice bile duct stenting can be used as a palliative treatment to achieve the purpose of bile drainage, thus improving the quality of life and prolonging survival.
