title: Laparoscopic leak-free technique for the treatment of choledochal cysts.
abstract: OBJECTIVE
  The aim of this report was to present our experience with a modified surgical technique designed for the treatment of choledochal cysts (CC) in children.
  
  
  METHODS
  Between June 2004 and February 2005, we operated on 6 patients with a diagnosis of type I CC by means of a "leak-free" technique that consists of a transient complete sealing of the hepatic duct for the duration of the dissection, and a single- or double laparoscopic running suture to build the end-to-side hepatico-jejuno anastomosis. There were 4 females and 2 males, whose age ranged between 45 days and 7 years (median, 45 months). All cases were performed with three trocars plus the scope, and two or three percutaneous stay-stitches to retract the liver. The end-to-side hepatico-jejuno anastomoses were done with 5.0 or 6.0 PDS. We left no drains.
  
  
  RESULTS
  The mean operative time was 335 minutes, and mean postoperative time to oral feeding was 44 hours. The mean hospital stay was 6 days (range, 5-10). No postoperative biliary leak was observed. A cosmetic result was excellent in all patients. In the follow-up (mean, 12 months), all patients were asymptomatic, had no intrahepatic biliary tree dilation, and had normal liver function tests.
  
  
  CONCLUSIONS
  Based on the results of our series, we think that the laparoscopic approach is suitable for these patients, but some surgical details should be followed to lower the complication rate. First, a temporary closure of the hepatic duct to prevent bile spillage during the dissection is important for keeping the area clean and thus reducing the operative time. Second, the use of a running suture for the hepatico-jejunostomy, even though it may be technically challenging, should always be attempted to avoid postoperative bile leaks in these high-flow anastomoses.
