Effects of conventional versus laparoscopic surgery in treatment of congenital bile duct dilatation: a comparative analysis

Objective To compare the clinical effects of conventional versus laparoscopic surgery in adults with congenital bile duct dilatation. Methods A retrospective analysis was performed on the clinical data of 37 patients with congenital bile duct dilation who were treated in our hospital from February 2011 to February 2013. All the 37 cases underwent bile duct cyst resection and common hepatic duct- jejunal Roux- en- Y anastomosis; 20 of them( study group) underwent laparoscopic surgery,while the other 17 cases( control group) underwent open surgery. The mean operative time,mean intraoperative blood loss,mean length of hospital stay after surgery,mean time to first flatus after surgery,and postoperative complications were compared between the two groups. Comparison of continuous data between the two groups was made by t test,while comparison of categorical data was made by chi- square test. Results Compared with the control group,the study group had a significantly longer operative time( P < 0. 05) but significantly less mean intraoperative blood loss,mean length of hospital stay after surgery,and mean time to first flatus after surgery( P < 0. 05). The incidence of postoperative complications showed no significant difference between the two groups( P > 0. 05). Conclusion Compared with conventional surgery,laparoscopic bile duct cyst resection and common hepatic duct- jejunal Roux- en- Y anastomosis is less invasive and safer and leads to faster recovery in adults with congenital bile duct dilation,and it is worthy of clinical application.
