Title: Giant choledochal cyst. Case report


Introduction: Choledochal cysts are congenital dilatations of the bile duct when they measure more than 10 centimetres are considered large. They are 1% of the benign cysts disorders. 80% is presented in schoolchildren and is presented more in women (4:1). These are abnormalities of the development of hepatic diverticulum which are responsible of abnormal connection of the pancreaticobiliary ducts.  Infants over the age of 1 year present clinically abdominal mass and abdominal pain. The classical triad is presented by 22% with jaundice, dolor abdominal and palpable lump. According to the location, the classification of Todani is divided in five types. Ultrasound is the imaging study, however, magnetic resonance cholangiopancreatography visualizes the anatomy of the bile duct and the pancreaticobiliary junction and dismiss vascular disorder. The only treatment with a successful resolution with 90% is surgery. The most commonly used technique is cystectomy with Roux-en-Y hepatic jejunoanastomosis 
Clinical case: 12-year-old female with a history of appendectomy and hepatitis A with multiple drug treatments with suspected of colitis and gastritis. She began with a 5-day history of predominantly epigastric abdominal pain, without irrradiation, burning, transflictive, progressive increase accompanied with jaundice, coluria, and constipation. She received pharmacological management presenting a partial recovery. After 72 hours, he presented nausea and vomiting. On physical examination, she presented a painful upon deep palpation in the epigastrium and under the right costal margin, with no evidence of peritoneal irritation. Report of laboratory studies suggestive of cholangitis and cholangioresonance with choledochal cyst (6.9 x 3 x 2.7 cm). She required resection and anastomosis of the hepatic duct with the duodenum by exploratory laparotomy, finding a Todani type I large choledochal cyst (10 x 15 cm). During postsurgical, she had an adequate evolution and follow-up without complications. Discussions and conclusions This pathology increases to 30% the risk of biliary malignancy (cholangiocarcinoma), so careful observation of clinical signs and symptoms could lead a timely diagnosis and an early treatment. The previous one helps to facilitate a surgical correction and reduce the risk of complications.
