Is it necessary to place a nasobiliary tube during ERCP stone removal from the bile duct?

ERCP generally refers to endoscopic retrograde cholangiopancreatography, an imaging procedure used to treat bile duct stones. This procedure often involves the placement of a nasobiliary tube for stone removal, although it is not always necessary in some cases. It is recommended to seek timely medical attention and receive treatment under the guidance of a professional physician.

In most cases, particularly when patients have large stones, multiple stones, bile duct strictures, or cholangitis, physicians typically choose to place a nasobiliary tube. Placement of the nasobiliary tube can help drain bile, relieve pressure within the bile duct, prevent bile reflux, reduce the incidence of postoperative cholangitis, promote bile duct healing, and decrease complications. In addition, the nasobiliary tube can serve as a channel for subsequent treatments, facilitating drug infusion or further endoscopic procedures.

Although placing a nasobiliary tube after endoscopic retrograde cholangiopancreatography is a common practice, it is not mandatory in all cases. For example, in some patients, if the procedure goes smoothly, there is no significant damage or edema to the bile or pancreatic ducts, and all stones have been completely removed, a nasobiliary tube may not be necessary. However, such cases are relatively rare and require assessment by a physician.

After the procedure, patients should closely monitor their condition and follow medical advice for postoperative care to promote recovery and minimize complications.
