Cancer of Pancreas, Pancreatic Neoplasm
Conditions
Brief summary
This study compares the 19G and 25G needles for procuring tissue samples from the pancreas during Endoscopic Ultrasound (EUS) procedures.
Detailed description
The study compares the median number of passes to establish a definitive diagnosis using the 19G or 25G needles. Also, the ability of both needles to procure a histological core tissue is assessed.
Interventions
A FNA needle will be used to biopsy the pancreatic mass. The rates of diagnostic accuracy (%) will be assessed. Diagnostic accuracy is defined as the proportion of patients in whom a definitive diagnosis can be obtained within a predetermined number of FNA passes.
The proportion of patients (%) in whom a histological tissue can be obtained when performing a biopsy of the pancreas using a specific needle will be assessed.

|---|---|---|
| Procurement of Histological Samples | 30 days | The ability of the 19G and 25G needles to obtain core (histological) tissue will be compared and a significance will be determined. |
| Needle Dysfunction | 2 hours | The percentage of cases in which needle dysfunction occurs will be compared between the 19G and 25G needle types. Needle dysfunction will be defined as the need to use more than one FNA needle per lesion in an individual patient. |
| Complications | 30 days | The safety profile of the 19 and 25G needles will be compared that includes bleeding, pancreatitis and perforation. |
