An Alternative Method Of Pancreatic Biopsy
It is reasonable to obtain a histological diagnosis before treating patients who have pancreatic masses and are unsuitable or unwilling to undergo surgery. As the pancreas is a deep seated organ surrounded by other vital structures, it is a challenge for the physician to obtain an adequate specimen for histological examination. Endoscopic ultrasound-guided biopsy of pancreatic masses has been proved to be a safe and effective method. 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 article to be published on December 21, 2009 in the World Journal of Gastroenterology addresses this question. A research team from Taiwan reviewed 34 CT-guided biopsies in patients with pancreas mass, of whom 24 (71%) had a direct path to the mass without passing through a major organ.
They drew a conclusion that it is feasible to perform transgastric biopsy of a pancreatic lesion using a large needle.
