The management of common bile duct after common bile duct exploration and stone extraction remains controversial. At present, T-tube drainage and primary suture of common bile duct are commonly adopted. Primary suture of common bile duct has more advantages and is more in line with the concept of enhanced recovery after surgery, which deserves widespread clinical application. However, T-tube drainage is more commonly used in clinical practice because surgeon may still have concerns about primary suture of common bile duct. Understanding the indications, improving suturing techniques, selective placement of stenting tube in common bile duct and mastering the key of placement are effective guarantees for achieving primary suture of common bile duct with better safety and prognosis.
