Randomized Controlled TrialDoes pancreatic duct stenting decrease the rate of pancreatic fistula following pancreaticoduodenectomy? Results of a prospective randomized trial.
Pancreatic duct stenting remains an attractive strategy to reduce the incidence of pancreatic fistulas following pancreaticoduodenectomy (PD) with encouraging results in both retrospective and prospective studies. We performed a prospective randomized trial to test the hypothesis that internal pancreatic duct stenting reduces the development of pancreatic fistulas following PD. Two hundred thirty-eight patients were randomized to either receive a pancreatic stent (S) or no stent (NS), and stratified according to the texture of the pancreatic remnant (soft/normal versus hard). ⋯ A nonstatistically significant increase in the pancreatic fistula rate in the S group persisted after adjusting for the operating surgeon and technical details of the operation (e.g., anastomotic technique, anastomotic orientation, pancreatic duct size, and number of intra-abdominal drains placed). In patients with soft pancreata, 63% percent of the pancreatic fistulas in stented patients required adjustment to the clinical pathway (including two deaths), compared to 47% of the pancreatic fistulas in patients in the NS group (P = 0.3). Internal pancreatic duct stenting does not decrease the frequency or the severity of postoperative pancreatic fistulas.

Postoperative pancreatic fistulas are not equivalent after proximal, distal, and central pancreatectomy.
It is uncertain whether postoperative pancreatic fistulas after distal and central pancreatectomies behave similarly to those after pancreaticoduodenectomy. To date, this concept has not been validated either clinically or economically. Overall, 256 consecutive pancreatic resections from October 2001 to February 2006 (184 pancreaticoduodenectomies, 66 distal pancreatectomies, and 6 central pancreatectomies) were evaluated according to the International Study Group of Pancreatic Fistula classification scheme. ⋯ Although reoperation rates for grade C fistulas were equivalent, intervals to reoperation were substantially longer after distal and central pancreatectomies. When classified according to International Study Group of Pancreatic Fistula criteria, clinically relevant pancreatic fistulas behaved differently depending on type of pancreatectomy. This translates into variable severity that guides management decisions, which ultimately dictate clinical outcomes and economic impact.
