Comparing the Diagnostic Efficacy of Different Suction Techniques for EUS-FNB of Pancreatic Solid Lesions

2019-09-27 06:30:41 | BioPortfolio


There are many factors that can affect the diagnostic yield of EUS-FNA, including lesion factors, the endoscoist experience, the needle size, the number of needle passes, and the suction technique. since diagnostic efficacy of different suction techniques for EUS-FNB is still uncertain, thus we decided to compare the diagnostic efficacy of three common methods: the 10 ml standard negative pressure, slow pull and wet suction.


the standard suction: after the needle is inserted in the mass, removing the stylet before performing EUS-FNA. Then attach a 10mL syringe to the end of needle. 20 times of for-backward Suction was applied after the lesion was punctured.

slow-pull : after the needle is inserted in the mass, slowly pull the stylet out while performing EUS-FNA with 20 times for-backward.

wet suction: after removing the stylet, the needle was flushed with 5mL of saline solution to replace the column of air with saline. A 10mL syringe was attached to the end of the needle. 20 times of for-backward Suction was applied after the lesion was punctured.

Proper positioning of the heart via a small left thoracotomy is the main challenge during off-pump minimally invasive coronary artery bypass grafting (MICS CABG). Here we report a novel technique for ...

Intra-pleural impedance sensor real-time tracking of pneumothorax in a porcine model of air leak.

In patients with alveolar-to-pleural air leak due to recent surgery or trauma, clinicians tend to manage chest tubes with suction therapy. Non-suction therapy is associated with shorter chest tube dur...

Medical and Biotech [MESH] Definitions

The removal of secretions, gas or fluid from hollow or tubular organs or cavities by means of a tube and a device that acts on negative pressure.

Removal of localized SUBCUTANEOUS FAT deposits by SUCTION CURETTAGE or blunt CANNULATION in the cosmetic correction of OBESITY and other esthetic contour defects.

Any suction exerted by the mouth; response of the mammalian infant to draw milk from the breast. Includes sucking on inanimate objects. Not to be used for thumb sucking, which is indexed under fingersucking.

Removal of the fetus from the uterus or vagina at or near the end of pregnancy with a metal traction cup that is attached to the fetus' head. Negative pressure is applied and traction is made on a chain passed through the suction tube. (From Stedman, 26th ed & Dorland, 28th ed)

Apparatus that provides mechanical circulatory support during open-heart surgery, by passing the heart to facilitate surgery on the organ. The basic function of the machine is to oxygenate the body's venous supply of blood and then pump it back into the arterial system. The machine also provides intracardiac suction, filtration, and temperature control. Some of the more important components of these machines include pumps, oxygenators, temperature regulators, and filters. (UMDNS, 1999)
