Long‐Term Outcomes of Congenital Biliary Dilatation Surgery: A Single‐Center Study Highlighting the High Incidence of Complications Within 5 Years

Abstract Background: Congenital biliary dilatation (CBD) is a rare anomaly often treated surgically, yet postoperative complications remain a concern. This study aimed to evaluate the incidence, timing, and risk factors of such complications after CBD surgery. Methods: A retrospective review was conducted on 184 patients with CBD who underwent either open or laparoscopic surgery, with a mean follow‐up of 9 years.
