Brief 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.

Outcome Measures

Primary Outcomes (1)

  • diagnostic accuracy

    compare the rate of diagnostic accuracy of EUS- FNB using the two different suction techniques (dry suction and wet suction) in patients with solid pancreatic lesions.

    12 months

Secondary Outcomes (5)

  • Samples tissue integrity

    12 months

  • Samples cellularity

    12 months

  • the diagnostic in relation to the number of needle passes

    12 months

  • Time (minutes) of the procedures with dry suction and wet suction

    12 months

  • Percentage of procedure related adverse events [Safety]

    24 months

Study Arms (2)

Dry suction group

EXPERIMENTAL

22G Franseen needle biopsy with dry suction technique(The puncture needle be filled with air)

Procedure: Dry suction

Wet suction group

ACTIVE COMPARATOR

22G Franseen needle biopsy with wet suction(The puncture needle be filled with saline before sugry)

Procedure: Wet suction

Interventions

Wet suctionPROCEDURE

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.

Wet suction group
Dry suctionPROCEDURE

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.

Eligibility Criteria

Age18 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age from 18 to 75 years;
  • Patients with solid pancreatic lesions evidenced by CT or MRI who do not have a histopathological diagnosis.
  • Plan to receive EUS-FNB.
  • Able to obtained informed consent.

You may not qualify if:

  • Had expected difficulty of endoscope insertion
  • That no lesion in the pancreas is identified by EUS
  • Use of anticoagulants/antiplatelet drugs that cannot be discontinued.
  • Had a bleeding tendency, defined as an international normalized ratio of the prothrombin time \>1.5 or a platelet count \<50,000 cells/mL
  • Other medical conditions that render the patient an unsuitable candidate for EUS-FNB.
  • Vulnerable groups such as pregnant women or patients with mental disorders;
  • Patients unable to understand and/or read the consent form.
