Canga's bead sign

Canga's Bead Sign is a clinical sign used in the field of medicine, specifically in gastroenterology. It is named after the physician who first described it, Dr. Canga.

Definition

Canga's Bead Sign refers to the presence of a string of small, bead-like dilations in the bile ducts that can be seen during an endoscopic retrograde cholangiopancreatography (ERCP). These dilations are typically indicative of a condition known as primary sclerosing cholangitis (PSC).

Clinical Significance

The presence of Canga's Bead Sign is a significant finding in the diagnosis of PSC, a chronic disease that causes inflammation and scarring of the bile ducts. The sign is not exclusive to PSC and can be seen in other biliary diseases as well. However, its presence, along with other clinical and laboratory findings, can help confirm a diagnosis of PSC.

Diagnosis

The diagnosis of PSC is often challenging due to the lack of specific symptoms in the early stages of the disease. The presence of Canga's Bead Sign during an ERCP can provide valuable information to the physician. However, it is important to note that the sign is not always present in patients with PSC, and its absence does not rule out the disease.

Treatment

The treatment of PSC is primarily aimed at managing the symptoms and slowing the progression of the disease. Currently, there is no cure for PSC. The presence of Canga's Bead Sign does not alter the treatment approach but can provide valuable information about the extent of the disease.
