Type I Choledochal Cyst in an Adult: Clinical Case and Surgical Management

Abstract

Choledochal cysts are rare congenital dilations of the biliary tract, most commonly diagnosed in childhood and less frequently identified in adults. When inadequately treated, they may lead to complications such as cholangitis, pancreatitis, and malignant transformation. We report the case of a 58-year-old female patient with chronic abdominal pain diagnosed with a type I choledochal cyst through imaging studies. The patient underwent surgical management with Roux-en-Y biliary reconstruction and presented a satisfactory postoperative course. This case highlights the importance of early diagnosis and surgical treatment, even in adult patients, to reduce complications and malignancy risk.
