Endoscopic ultrasound-guided biopsy of pancreatic masses has been proved to be a safe and effective method as an alternative method of pancreatic biopsy by new research.
However, if the hospital has no such facilities or patients are unwilling or intolerant of the procedure, computed tomography (CT)-guided biopsy is an alternative method.
A research team from Taiwan reviewed 34 CT-guided biopsies in patients with pancreas mass, of whom 24 had a direct path to the mass without passing through a major organ.
Their results showed tumor tissues were obtained in nine pancreatic biopsies, and histologic specimens for diagnosis were obtained in all cases.
An immediate imaging study and clinical follow-up detected neither hemorrhage nor peritonitis. No delayed procedure-related complication was seen during the survival period of all patients.
They drew a conclusion that it is feasible to perform transgastric biopsy of a pancreatic lesion using a large needle.
The research has been published in the World Journal of Gastroenterology.
