Choledochal cysts are dilated portions of the biliary tract that account for 1% of all benign biliary diseases. It is prevalent among Asian and female populations and the incidence is 1:100,000-150,000. Among the different types, only 15-35% of all choledochal cysts are type IV cysts, with type I being the most common representing 50-80%. Clinical presentation and therapy of biliary cysts (BC) differ depending on the type. We present a case of a 2-year-old male who presented with non-specific symptoms of multiple episodes of vomiting. Laboratory investigations revealed raised alkaline phosphatase and gamma-glutamyl transpeptidase. His symptoms of acute pancreatitis were resolved with conventional therapy. Ultrasonography of the abdomen showed intra and extra-hepatic cystic biliary tree dilatation suggestive of choledochal cyst Type IV A. Choledochal cysts present with clinical features varying with age and anatomical variants and can pose challenges in management that can be addressed by surgery to avoid further complications.

Choledochal cyst or biliary tract cyst is a pathological condition characterized by abnormal dilation of the hepatobiliary system. In veterinary medicine, case descriptions and histological characterizations of this biliary malformation are scarce, requiring reliance on data from human medicine. A presumptive diagnosis typically involves imaging studies, with histopathological examination required for confirmation.

Choledochal cysts (CCs) are rare cystic dilations of the intrahepatic and/or extrahepatic bile ducts. Malignancies arising during follow-up after excision of CCs have been reported in both children and adults, with no typical time frame for malignancy development. We present a case of a patient diagnosed with CCs 36 years ago, who underwent resection and subsequently developed cancer.

Department of Pediatric Surgery, West China Hospital, Sichuan University, No.37, Guoxue Alley, Chengdu, Sichuan, China.

Background: We conducted this retrospective study to investigate the characteristics of the learning curve of total robotic jejunojejunostomy during choledochal cyst excision in pediatrics.

Methods: The study analyzed a database of medical records from the first 54 consecutive patients who underwent total robotic jejunojejunostomy during choledochal cyst excision by a single surgeon. Baseline information and postoperative outcomes were collected, and learning curves were assessed using the cumulative sum (CUSUM) method.

Background: Congenital biliary dilatation (CBD) is a congenital malformation of the main biliary tract usually associated with the pancreatobiliary maljunction (PBM), determining stone formation, cholangitis, pancreatitis, and cholangiocarcinoma. The role of endoscopic retrograde cholangiopancreatography (ERCP) in treatment and diagnosis has not been established yet. Therefore, the aim of our study is to define the actual role of ERCP in children with CBD.
