The methods of ERCP to remove common bile duct stones include two methods: balloon, basket, and some derived methods. With the development of technology, the choice of basket or balloon depends largely on the operator's experience and preference. For example, stone extraction baskets are used as the first choice in Europe and Japan because the stone extraction basket is stronger and has stronger traction than the balloon. However, due to its structure, the stone extraction basket is not easy to grasp smaller stones. Especially when the nipple incision is insufficient or the stones are larger than expected, the basket stone removal may cause stone incarceration. Considering these factors, the method of balloon stone removal may be more used in the United States. Several studies have shown that the success rate of mesh basket and balloon stone removal methods is similar when the stone diameter is less than 1.1 cm, and there is no statistical difference in complications. When it is difficult to remove stones from the basket, the method of laser lithotripsy can be used to further solve the difficult stone removal. Therefore, in the actual operation, it is necessary to comprehensively consider the size of the stone, the experience of the operator, and other factors, and choose a reasonable method of stone removal.

Frequently Asked Questions (FAQ)
What are the primary methods for removing common bile duct stones?
The primary methods include using balloons and baskets, along with derived techniques.
How does the choice between a basket and a balloon vary by region?
Stone extraction baskets are often preferred in Europe and Japan due to their strength, while balloon methods might be more common in the United States, considering factors like stone size and operator preference.
What are the potential risks of using a stone extraction basket?
Stone incarceration can occur, especially with smaller stones, insufficient nipple incisions, or unexpectedly large stones.
When is a balloon method for stone removal preferred?
Balloon methods might be considered when basket removal is challenging or when managing smaller stones.
What is the success rate comparison between baskets and balloons for smaller stones?
For stones less than 1.1 cm in diameter, studies show similar success rates and complication profiles between mesh baskets and balloons.
What alternative method can be used for difficult stone removal?
Laser lithotripsy can be employed to address stones that are difficult to remove with conventional basket methods.
