OBJECTIVE:Pancreatic fistula is a leading cause of morbidity and mortality after pancreaticoduodenectomy. External drainage of pancreatic duct with a stent has been shown to reduce pancreatic fistula rate of pancreaticojejunostomy in a few retrospective or prospective nonrandomized studies, but no randomized controlled trial has been reported thus far. This single-center prospective randomized trial compared the results of pancreaticoduodenectomy with external drainage stent versus no stent for pancreaticojejunal anastomosis. METHODS: A total of 120 patients undergoing pancreaticoduodenectomy with end-to-side pancreaticojejunal anastomosis were randomized to have either an external stent inserted across the anastomosis to drain the pancreatic duct (n = 60) or no stent (n = 60). Duct-to-mucosa anastomosis was performed in all cases. RESULTS: The 2 groups were comparable in demographic data, underlying pathologies, pancreatic consistency, and duct diameter. Stented group had a significantly lower pancreatic fistula rate compared with nonstented group (6.7% vs. 20%, P = 0.032). Radiologic or surgical intervention for pancreatic fistula was required in 1 patient in the stented group and 4 patients in the nonstented group. There were no significant differences in overall morbidity (31.7% vs. 38.3%, P = 0.444) and hospital mortality (1.7% vs. 5%, P = 0.309). Two patients in the nonstented group and none in the stented group died of pancreatic fistula. Hospital stay was significantly shorter in the stented group (mean 17 vs. 23 days, P = 0.039). On multivariate analysis, no stenting and pancreatic duct diameter <3 mm were significant risk factors of pancreatic fistula. CONCLUSION:External drainage of pancreatic duct with a stent reduced leakage rate of pancreaticojejunostomy after pancreaticoduodenectomy.
