Laparoscopic management of choledochal cysts: is a keyhole view missing the big picture?

Abstract

In recent years, numerous articles have promoted laparoscopic surgical treatment of choledochal cysts in children. Most of these reports assert that laparoscopic excision and biliary reconstruction are as safe as open surgery and achieve equivalent or better results. However, these conclusions are based on retrospective analyses with median follow-up periods that rarely exceed 5 years. Closer scrutiny of the laparoscopic literature indicates that the optimum procedure for treating type I and most type IVa choledochal cysts, namely radical excision of the extrahepatic bile ducts and reconstruction by wide hilar hepaticoenterostomy, preferably hepaticojejunostomy, is not being carried out in most cases. Performing a less radical excision exposes patients to a greater long-term risk of a bilioenteric stricture and its complications and malignant change in residual extrahepatic bile ducts. Currently, the long-term outcomes of surgery for choledochal cysts are being eclipsed by the short-term gains of laparoscopic techniques. The prime objective in the surgical management of choledochal cysts is the long-term health of the patient; laparoscopic techniques are simply another method of performing the surgery and they should not become the standard of care unless long-term outcomes are similar to best practice open surgery.
