Effect of the RTPBD Tube Method on Pancreatic Juice and Bile Drainage after Pancreaticoduodenectomy

Thirty-eight patients who underwent pancreaticoduodenectomy during the past 8 years were divided into 2 groups according to the pancreatic and biliary drainage method. One was the previous method of T-tube and tube jejunostomy (19 cases), and the other was the RTPBD tube method (retrograde transhepatic pancreatico-biliary drainage tube method) (19 cases), the postoperative course and complications in the 2 groups were compared. Drainage volume of pancreatic juice was 163.5±13.7 ml/day in the previous method, and 113.4±15.2 ml/day in the RTPBD tube method, and that of bile was 292.3±24.4 ml/day in the previous method, and 323.4 ± 65.2 ml/day in the RTPBD tube method. These differences were not significant. Postoperative increase in ALP was found in 50-60%, and postoperative icterus was found in 20-30% of both groups. Anastomotic leakage of the choledochojejunostomy was found 1 case (4.5%) by the previous method, and 1 case (6.6%) by the RTPBD tube method, that of pancreaticojejunostomy was found in 2 cases (9.5%) by the previous method, and 3 cases (18.7%) by the RTPBD tube method, and these differences were not significant. The RTPBD tube method was easy to perform and was as effective as pancreatic juice and bile drainage after pancreaticoduodenectomy.
