Comparision of EUS-FNB Techniques for Diagnose of Solid Pancreatic Lesions

NCT05549856 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 200

No results posted yet for this study

Summary

Studies have shown that the wet-suction technique in EUS-FNA generates better histological diagnostic accuracy and specimen quality than the dry-suction technique. However, studies on wet suction on the diagnostic accuracy of EUS-FNB is small and the conclusions are controversial. Besides, the optional numeber of passes for EUS-FNB has not been determined.

Conditions

  • Solid Pancreatic Lesions
  • EUS-FNB

Interventions

PROCEDURE

Wet suction

The pancreatic solid lesions will be puncture with the 22G Acquire needle (Boston Scientific Corporation, Marlborough, MA, USA). Before puncturing the lesion, flush the needle with 5ml saline, then use a 10 ml syringe in order to replacing the column of air with fluid. After puncture, monitoring the puncture needle under US guidance in real time, the needle was moved back and forth about 10-20 times within the lesion using a fanning technique.

PROCEDURE

Dry suction

The pancreatic solid lesions will be puncture with the 22G Acquire needle (Boston Scientific Corporation, Marlborough, MA, USA). The stylet is removed and a 10 ml air-filled pre-vacuum syringe is attached. After puncture, monitoring the puncture needle under US guidance in real time, the needle was moved back and forth about 10-20 times within the lesion using a fanning technique.
