Abstract
To compare morbidity and mortality rates of stented versus nonstented pancreaticojejunostomy after partial pancreatoduodenectomy. Despite a marked reduction in the mortality rate after partial pancreatoduodenectomy in recent years, leakage of the pancreaticojejunostomy still occurs in 5% to 25% of patients and remains the major source of complications. The authors compared the morbidity and mortality rates of 85 consecutive patients who had a partial pancreatoduodenectomy with (n = 44) or without (n = 41) temporary stented external drainage of the pancreatic duct between 1994 and 1997. A pancreatic fistula was diagnosed in 3 of the 44 patients (6.8%) with stents versus 12 of the 41 patients (29.3%) without stents. Surgical reintervention was necessary in 1 of the 3 patients with a pancreatic fistula in the stented group and 3 of the 12 patients with a pancreatic fistula in the nonstented group. There were two deaths after surgery, both in the nonstented group. The median hospital stay after surgery was 13 days in patients with stents and 29 days in patients without stents. In this nonrandomized prospective observational study, temporary external drainage of the pancreatic duct with a PVC tube significantly reduced the leakage rate of the pancreaticojejunostomy as well as the duration of hospital stay after partial pancreatoduodenectomy. Although promising, these observations require confirmation by further studies.
