NCT05617872Completed
Vinegar-induced Collection of Duodenal Pancreatic Juice Via Endoscopic Ultrasound
Source: ClinicalTrials.gov · Last updated 2 Apr 2026
Brief summary (registry, in English)
The goal of this clinical trial is to learn about the feasibility of collecting pancreatic juice through duodenal aspiration by ultrasound endoscopy (EUS) for molecular marker testing after intraduodenal infusion of vinegar in patients with suspected pancreatic cancer and who are scheduled to have endoscopic ultrasound with fine needle aspiration (EUS-FNA). The main questions it aims to answer are: * Is vinegar-induced collection of duodenal pancreatic juice via endoscopic ultrasound feasible? * What is the best operating condition (amount of vinegar, collection time, etc.) of vinegar-induced collection of duodenal pancreatic juice via endoscopic ultrasound? Participants will have EUS as scheduled, during which different amount of vinegar will be infused into duodenum and then pancreatic juice be collected for different time via suction by EUS. Researchers will compare the amount of collected pancreatic juice and molecular marker level in different groups to determine the best operating condition for vinegar-induced collection of duodenal pancreatic juice via endoscopic ultrasound.

Built from the registry fields of ClinicalTrials.gov. It describes the study, not your situation.
Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Other illness
- The patient's clinical and imaging features do not support the diagnosis of suspected pancreatic cancer, judged by 3 endoscopists
- The patient is unsuitable for EUS-FNA because of his/her general condition, or contraindicated for anesthesia
- The patient cannot understand the conditions and objectives of this study, or refuse to participate in the study
Other
- The patient refuses to have EUS-FNA
- The patient's imaging suggests severe pancreatic duct obstruction
Who the study is looking for
- Age: 18 years old or older
- Diagnosis: CT, MRI, transabdominal ultrasound or other imaging examinations showed a pancreatic mass, and 3 endoscopists agreed on the diagnosis of suspected pancreatic cancer
- EUS-FNA is required to perform further treatment strategy
- The patient can understand the study protocol, is willing to participate in the study and can provide written informed consent
Age in the registry: 18 years to - · Sex: All · Does not accept healthy volunteers
