Active Comparator: 1
closed suction drainage group (CD group)
Procedure: closed suction drainage of pancreatic duct
A Fr 5-8 silastic polyethylene pediatric feeding tube with multiple side-holes is inserted 2 cm into the pancreatic duct. The catheter exited via a small enterotomy in the jejunal loop of the distal portion of the hepaticojejunostomy. Totally externalized pancreatic stents were connected to the aspiration bag of a Jackson-Pratt drain to generate negative pressure or to a bile bag for natural drainage.

Pancreaticojejunal anastomosis leakage is a major complication after pancreatoduodenectomy and various technical methods have been examined to improve the situation, e.g., pancreatic duct occlusion, anastomosis reinforcement with fibrin glue, placement of an internal stent, and pancreaticogastrostomy. However, none of these methods have been successful at improving results according to the findings of prospective randomized studies. Some retrospective studies have reported a low pancreatic fistula rate when a catheter is inserted into the pancreatic duct to externally drain pancreatic juice. Furthermore, a recent prospective randomized trial showed that external drainage of the pancreatic duct decreased the rate of pancreatic fistula formation indicating that diverting pancreatic juice from an anastomosis can theoretically reduce the incidence of pancreaticojejunostomy anastomotic leakage. We propose that active drainage of pancreatic juice using suction drainage might maximize the advantage of a stent and finally reduce pancreaticojejunal anastomosis leakage.
We will enroll all patients who underwent duct-to-mucosa pancreaticojejunostomy reconstruction after pancreatoduodenectomy, and randomly allocate them to two groups of closed suction drainage group (CD group) and natural drainage group (ND group) just after operations.
Preoperative demographic and clinical data, and surgical procedure, pathologic diagnosis, postoperative course and complications details were collected prospectively.
The primary study endpoints were; pancreatic fistula rates, severity of pancreatic fistulas, postoperative complications, postoperative length of hospital stay, and hospital mortality rate. Pancreatic fistula was defined as any measurable drainage from an operatively placed drain (or a subsequently placed percutaneous drain) on or after postoperative day 3, with an amylase content greater than 3 times the upper limit of normal serum amylase level (i.e., >300 IU/L)(International Study Group for Pancreatic Fistulas (ISGPF) definition) or on or after postoperative week 1 drainage of more than 30 mL of fluid with an amylase level higher than 600 U/dL(Seoul National University Hospital (SNUH) definition). In addition, fistula severity was graded as A, B, C according to ISGPF clinical criteria as follows; grade A fistula - a transient, asymptomatic fistula with only elevated drain amylase levels and treatments or deviation in clinical management are not required; grade B fistula - a symptomatic, clinically apparent fistula requiring diagnostic evaluation and therapeutic management; and grade C fistula - a severe, clinically significant fistula requiring a major deviations in clinical management and unequivocal aggressive therapeutic interventions. Major pancreatic leakage was defined as drainage of more than 200 mL of fluid or the development of an intra-abdominal abscess.
