About this study
Official title: Randomized Controlled Trial on the Evaluation of Pylorus-ring in Pancreaticoduodenectomy
The purpose of this study is to clarify whether resecting pylorus-ring decreases delayed gastric emptying after pancreaticoduodenectomy and improves postoperative quality of life (QOL).
Read the detailed description
The purpose of this study is to clarify whether resecting pylorus-ring decreases delayed gastric emptying after pancreaticoduodenectomy and improves postoperative quality of life(QOL)compared with preserving pylorus-ring. Delayed gastric emptying after pancreaticoduodenectomy are important to affect the postoperative course and QOL. However, there is no report that demonstrates the postoperative course between resecting pylorus-ring and preserving pylorus-ring. We conducted a prospective randomized trial on 130 patients who underwent pancreaticoduodenectomy comparing resecting pylorus-ring and preserving pylorus-ring.
The primary endpoint was defined as the decrease of delayed gastric emptying. The secondary endpoints were QOL, mortality and morbidity, including pancreatic fistula, 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 Wakayama Medical University Hospital(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 with a previous gastric resection, and 4) patients without an informed consent.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
pylorus-preserving pancreaticoduodenectomyProcedure or surgery
pylorus-preserving resection is division of the duodenum 3-4cm distal to the pylorus
pylorus-resecting pancreaticoduodenectomyProcedure or surgery
In PrPD, the stomach is divided just above the pylorus ring. The nearly total stomach more than 95% was preserved.

Questions about this trial
What is this clinical trial studying?
A study testing pylorus-preserving pancreaticoduodenectomy and pylorus-resecting pancreaticoduodenectomy 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 27 Jun 2011. 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?
delayed gastric empty after pancreaticoduodenectomy (time frame: 1 month). 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 NCT00639314, 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 27 Jun 2011; AzTrials last refreshed its copy on 8 Nov 2026.
