Pancreaticojejunal anastomosis leakage is a major complication after pancreatoduodenectomy and various technical methods have been examined to improve the situation.However, none of methods have been successful at improving results according to the findings of prospective randomized studies. We propose that active drainage of pancreatic juice using suction drainage might maximize the advantage of a stent and finally reduce pancreaticojejunal anastomosis leakage.
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.

Principal hypothesis: A low suction drainage (-50 mmHg) reduce a 25% the blood loss with respect a standard closed drainage (-700 mmHg) following total knee arthroplasty.
BACKGROUND Ultrasonography-guided percutaneous drainage for pancreatic fluid collections is associated with a high recurrence rate and endoscopic ultrasonography (EUS)-guided drainage is a valuable ap...
Pancreatic pseudocyst (PP) and walled-off necrosis can be managed endoscopically, percutaneously or surgically, but with diverse efficacy.
Percutaneous or endoscopic drainage was usually performed as the first step in step-up approach for infected pancreatic necrosis (IPN). However, drainage was unnecessary or unavailable in some patient...
Postoperative pancreatic collection (POPC) is a frequent complication after pancreatectomy. Although percutaneous drainage (PD) has been the treatment of choice for POPC with encapsulation, endoscopic...
A 36-amino acid pancreatic hormone that is secreted mainly by endocrine cells found at the periphery of the ISLETS OF LANGERHANS and adjacent to cells containing SOMATOSTATIN and GLUCAGON. Pancreatic polypeptide (PP), when administered peripherally, can suppress gastric secretion, gastric emptying, pancreatic enzyme secretion, and appetite. A lack of pancreatic polypeptide (PP) has been associated with OBESITY in rats and mice.
Extracts prepared from pancreatic tissue that may contain the pancreatic enzymes or other specific uncharacterized factors or proteins with specific activities. PANCREATIN is a specific extract containing digestive enzymes and used to treat pancreatic insufficiency.
A pancreatic trypsin inhibitor common to all mammals. It is secreted with the zymogens into the pancreatic juice. It is a protein composed of 56 amino acid residues and is different in amino acid composition and physiological activity from the Kunitz bovine pancreatic trypsin inhibitor (APROTININ).
A true cyst of the PANCREAS, distinguished from the much more common PANCREATIC PSEUDOCYST by possessing a lining of mucous EPITHELIUM. Pancreatic cysts are categorized as congenital, retention, neoplastic, parasitic, enterogenous, or dermoid. Congenital cysts occur more frequently as solitary cysts but may be multiple. Retention cysts are gross enlargements of PANCREATIC DUCTS secondary to ductal obstruction. (From Bockus Gastroenterology, 4th ed, p4145)
