Background Biliary cysts are duct dilatation that can occur on all biliary ducts, 20–25% is diagnosed in adults. The classic triad for the clinical presentation consists on abdominal pain, jaundice and abdominal mass. The standard treatment is surgical resection and bilioenteric anastomosis. The objective of this study is to analyze the prevalence and characteristics of biliary cysts in our center. Methods This is an observational retrospective study, we included patients older than 16 years old with biliary cyst from march 1989 to February 2015. The demographic and clinical information was collected from the charts and electronic records available at our Hospital. Results Biliary cysts were reported on 52 patients, only 25 clinical charts were available. The main symptom was abdominal pain in 21 (84%). The diagnosis was performed with abdominal ultrasound in 16 (64%). The most frequent type was IA in 9 (36%). All patients were treated with surgery as a definitive management. Discussion Vague clinical presentation results on a delay of the diagnosis and treatment. Surgical resection is recommended for patients since they have an increased risk for malignant transformation. Postoperative complications in our patients were stenosis of bilioenteric anastomosis in 3 (12%) patients. Conclusions Biliary cysts require an accurate diagnosis and surgical treatment in order to decrease the risk of malignant transformation and progression of the disease. Precise surgical treatment is needed to achieve complete resection and a long term postoperative follow up is mandatory. Highlights ? The objective is to analyze prevalence and characteristics of biliary cysts in our center. ? Vague clinical presentation results on a delay of the diagnosis and treatment. ? Surgery is recommended because of increased risk for malignant transformation. ? Most common complication in our patients was stenosis of bilioenteric anastomosis.
