These are patients who will have endoscopic ultrasound-guided fine needle aspiration using the standard suction FNA technique: 15 to-and-fro movements within the lesion will be performed with use of 10cc suction syringe.

These are patients who will have endoscopic ultrasound-guided fine needle aspiration using the capillary suction FNA technique: 15 to-and-fro movements within the lesion will be performed with simultaneous minimal negative pressure provided by pulling the needle stylet slowly and continuously.

Capillary suction technique for EUS FNA

Mouen A Khashab, MD

The aim of this study is to compare Endoscopic Ultrasound and Fine Needle Aspirate with a standard 22-gauge needle using either "standard-suction" or "capillary suction" methods for solid pancreatic lesions. Investigators hope to discover the best technique for obtaining diagnostic material when patients with a pancreatic mass undergo endoscopic ultrasound and fine needle aspirate procedure.

There are currently several techniques for obtaining tissue during endoscopic ultrasound and fine needle aspirate. The procedure will be performed by either the capillary suction technique or no suction technique.

The endosonographers were not blinded to the procedure technique. A small possibility that cytotechnicians may have witnessed the technique. Cellularity of the specimens were not quantified. A 6 months follow-up may not detect all false negatives

gold standard is defined as follows: for resectable cases, surgical histology was considered the gold standard. For unresectable or benign cases, positive cytology (with compatible clinical outcome) at 6-month follow-up was considered gold standard. Negative cytology was confirmed with clinical data and/or imaging at 6 month follow-up.

Patients With Positive Gold Standard

Patients With Negative Gold Standard

The discrepancy between the number of analyzed patients and the number of patients in the Participant Flow section is due to the fact that calculation of sensitivity was done based on the Per Protocol analysis.
