About this study
Official title: Prospective, Randomized, and Controlled Trial That Lost Stent Versus External Stent of Pancreaticojejunostomy After Pancreaticoduodenectomy
The purpose of this study is to determine which stent type is effective in the decrease of postoperative stay and complications across pancreaticojejunostomy after pancreaticoduodenectomy.
Read the detailed description
This study compared the postoperative hospital stay and complications of lost stent with external stent after pancreaticoduodenectomy. The complications of pancreaticoduodenectomy are important to affect the postoperative course, and, a stent tube often places across pancreaticojejunostomy to reduce complications. However, there is no report that demonstrates the postoperative course between pancreatic stent types. We conducted a prospective randomized trial on 100 patients who underwent pancreaticoduodenectomy comparing external stent and lost stent.
The primary endpoint was defined as postoperative hospital stay. The secondary endpoints were mortality and morbidity, including pancreatic fistula, delayed gastric emptying, intra-abdominal hemorrhage, and intra-abdominal abscess. Patients were recruited into this study before surgery, on the basis of whether pancreatic head resection was anticipated at WMUH for pancreatic head and periampullary disease, and appropriate informed consent was obtained. Exclusion criteria was 1) patients with severe complications which were possible to prolong hospital stay, 2) patients who were diagnosed inadequacy for this study by a physician, 3) patients who could not be placed a pancreatic stent tube, and 4) patients without an informed consent.

Also called polyethylene pancreatic drainage tube(S/N MD41515)
External drainage tube was intubated with a 5F polyethylene pancreatic drainage tube with a small knob (Sumitomo Bakelite Co., Japan)(MD41515) across pancreaticojejunostomy in pancreaticoduodenectomy, and exteriorized through the jejunal limb.
internal drainage tube [polyethylene pancreatic drainage tube]Device
Also called polyethylene pancreatic drainage tube(S/N MD41515)
Internal drainage tube was intubated 5cm length of stent tube cut a 5F polyethylene pancreatic drainage tube with a small knob across pancreaticojejunostomy in pancreaticoduodenectomy, and pancreatic juice was led to reconstructed jejunum.
| Study group | Role | What they receive |

Questions about this trial
What is this clinical trial studying?
A study testing external drainage tube [polyethylene pancreatic drainage tube] and internal drainage tube [polyethylene pancreatic drainage tube] in people with Pancreatic Cancer and Bile Duct Cancer, run by Wakayama Medical University at 1 site in Japan.
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 4 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 18 Jan 2010. 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 Japan. 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
the length of hospital stay after pancreaticoduodenectomy (time frame: the day of discharge). 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 NCT00628186, which also lists 11 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 18 Jan 2010.
