All types of choledochal cyst require which of the following procedures?

The procedure that all types of choledochal cyst require is resection with concomitant cholecystectomy and common bile duct (CBD) removal. Choledochal cysts are congenital bile duct anomalies that can lead to complications such as biliary obstruction, infection, pancreatitis, and cholangiocarcinoma if left untreated.

The surgical treatment generally involves the excision of the cyst along with the gallbladder and part of the affected bile duct, followed by reconstruction of the biliary system. This approach addresses the primary pathological conditions associated with choledochal cysts, such as the risk of malignancy and the potential for biliary complications, while restoring normal biliary drainage.

Endoscopic retrograde cholangiopancreatography (ERCP) is typically used for diagnosis and sometimes for therapeutic interventions in the setting of biliary obstruction, but it does not address the cyst itself. Monitoring alone does not provide a definitive treatment and leaves the patient at risk for complications. Laparoscopic cholecystectomy, while it may be a part of the management, does not suffice on its own without addressing the cyst. Thus, the most definitive and appropriate treatment for all types of choledochal cysts is the
