NCT05628454

Brief Summary

The purpose of this study was to compare the accuracy and sensitivity of slow-pull capillary technique, traditional suction aspiration and non negative pressure puncture in the diagnosis of mediastinal and/or hilar lymph node enlargement by ultrasound bronchoscopic lymph node biopsy.

Outcome Measures

Primary Outcomes (1)

  • Diagnostic accuracy of three different puncture methods according to pathological diagnosis

    The final pathological diagnosis was based on all available cytological and histological samples. In cases with negative pathological results , we continue to follow up the patients for ⩾6months.

    6 months

Secondary Outcomes (3)

  • Blood contamination of samples

    1 week

  • Bleeding of operation

    1 week

  • Acquisition of tissue core of three different puncture methods according to the judgment of the pathologist

    1 week

Study Arms (3)

EBUS-TBNSP

EXPERIMENTAL

The slow-pull capillary technique was performed as follows: after identification and measurement of the target lymph node, a needle was used to puncture the lymph node with the stylet in place.At the same time, the stylet was slowly and continuously pulled to create weak negative pressure.

Procedure: Endobronchial ultrasound-guided transbronchial needle Slow-pull capillary sampling

EBUS-TBNA

EXPERIMENTAL

The operation steps are the same as above, but the negative pressure device of 10ml syringe is connected behind the puncture needle.

Procedure: Endobronchial ultrasound-guided transbronchial needle aspiration

EBUS-TBNCS

EXPERIMENTAL

The operation steps are the same as above, but there is no negative pressure device behind the puncture needle

Procedure: Endobronchial ultrasound-guided transbronchial needle capillary sampling

Interventions

The slow-pull capillary technique was performed as follows: after identification and measurement of the target lymph node, a needle was used to puncture the lymph node with the stylet in place.At the same time, the stylet was slowly and continuously pulled to create weak negative pressure.

Also known as: Slow-pull capillary technique
EBUS-TBNSP

The operation steps are the same as above, but the negative pressure device of 10ml syringe is connected behind the puncture needle.

Also known as: Standard suction
EBUS-TBNA

The operation steps are the same as above, but there is no negative pressure device behind the puncture needle

Also known as: Fine needle sampling without suction
EBUS-TBNCS

Eligibility Criteria
