About this study

Official title: Randomised Prospective Study of Clinical Outcomes After Closed Suction Drainage and Natural Drainage of the Pancreatic Duct in Pancreaticojejunostomy After Pancreatoduodenectomy

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.

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • closed suction drainage of pancreatic ductProcedure or surgery

    Also called pancreaticojejunostomy

    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.

  • natural drainage of pancreatic ductProcedure or surgery

    Also called pancreaticojejunostomy

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients With Pancreatic Fistula

    pancreatic fistula rate is stratified according to ISGPF criteria.

    Grade A; No major impact Grade B; Clinically relevant fistula, specific treatment may be required Grade C; Most severe form of fistula, with a high mortality rate

    Measured: postoperative 1 week

Secondary outcomes (1)
  1. Severity of Pancreatic Fistulas

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing closed suction drainage of pancreatic duct and natural drainage of pancreatic duct in people with Pancreatic Fistula, run by Seoul National University Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 May 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 May 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Patients With Pancreatic Fistula (time frame: postoperative 1 week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00679952, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 May 2014.
