Vinegar trick may help detect pancreatic cancer earlier
NCT ID NCT05617872
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether squirting vinegar into the small intestine during an endoscopy can help collect pancreatic juice for cancer testing. 75 people with suspected pancreatic cancer took part. The goal was to see if this method works and find the best amount of vinegar and collection time. Results could lead to a simpler way to detect pancreatic cancer markers.

Inclusion Criteria: * 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 Exclusion Criteria: * The patient's clinical and imaging features do not support the diagnosis of suspected pancreatic cancer, judged by 3 endoscopists * The patient refuses to have EUS-FNA * The patient is unsuitable for EUS-FNA because of his/her general condition, or contraindicated for anesthesia * The patient's imaging suggests severe pancreatic duct obstruction * The patient cannot understand the conditions and objectives of this study, or refuse to participate in the study
