A Prospective Comparison of EUS-Guided FNA Using 25-Gauge and 22-Gauge Needles

Table 1

Scoring of visibility of needle, ease of puncture, and quantity of specimen obtained.

Visibility of needle	0: poor	Needle tip is absolutely invisible.
	1: good	The needle tip is visible, although invisible intermittently during the procedure.
	2: excellent	The needle tip is visible throughout the procedure.
Ease of puncture	0: poor	Impossible to puncture.
	1: good	The needle bends during the procedure, or the target lesion is pushed away from the transducer of the echoendoscope at the time of puncture.
	2: excellent	The puncture is done effortlessly and the needle never bends during procedure.
Quantity of the specimen obtained	0: poor	No specimen
	1: good	Although a small specimen is obtained, definitive diagnosis is difficult.
	2: excellent	Adequate for definitive diagnosis.
