DiscussionDiscussion
Previous studies have proved cost-Previous studies have proved cost-effectiveness and decreased hospital stay effectiveness and decreased hospital stay for laparoscopic biliary explorationfor laparoscopic biliary explorationSurgeons who overcome learning curve Surgeons who overcome learning curve are still reluctant to adopt techniqueare still reluctant to adopt technique51.3% of patients who have clinical, 51.3% of patients who have clinical, ultrasound or biochemical suspicion of ultrasound or biochemical suspicion of duct stones would have unnecessary duct stones would have unnecessary preoperative investigationspreoperative investigations

ConclusionConclusion
Laparoscopic single session management Laparoscopic single session management of ductal stones is cost-effective with of ductal stones is cost-effective with shorter hospital stay than multiple stage shorter hospital stay than multiple stage managementmanagement Simple transcystic manoeuvres may clear Simple transcystic manoeuvres may clear the ducts without formal explorationthe ducts without formal exploration This technique is advocated in preference This technique is advocated in preference to endoscopic clearance for surgeons to endoscopic clearance for surgeons beyond the learning curvebeyond the learning curve
