Objective:To investigate the shortterm therapeutic effects of the Uncut Roux-en-Y choledochojejunostomy. Methods:To analyze a total of 41 cases of Uncut Roux-en-Y choledochojejunostomy and compare with 48 cases underwent RouxenY choledochojejunostomy from April 2005 to December 2006. Results:The anastomotic time of the Uncut Roux-en-Y choledochojejunostomy is shorter (P<0.05).The period of recovery of bowel sound and flatus are earlier in the patients with Uncut Roux-en-Y choledochojejunostomy than that with Roux-en-Y choledochojejunostomy (P<0.05).The serum level of total bilirubin decreases in both Uncut RouxenY choledochojejunostomy group and Roux-en-Y choledochojejunostomy group with no statistical differences. Conclusion:The shortterm therapeutic effects of the Uncut Roux-en-Y choledochojejunostomy is better than Roux-en-Y choledochojejunostomy,but the further therapeutic effect need more study.
