Accuracy and Quality Assessment of EUS-FNA: A Single-Center Large Cohort of Biopsies

Table 2

FNA results for abdominal lymph nodes.

Region	Cases	FNA nondiagnostic or false negative	Percent of FNA diagnostically useful
Nodes alone	9	3	66.67
With pancreas	8	3	62.50
With stomach	2	0	100.00
With liver	2	0	100.00
With adrenal	1	0	100.00
With mediastinum	3	0	100.00
With mediastinum; and pancreas	1	1	0.00
With other (ascites)	1	0	100.00
Total	27	7	70.47

Displayed in this chart are the various regions from which EUS-guided FNA was performed on abdominal lymph nodes either alone or in combination with other organs. Alongside each value is the number of cases that the FNA proved unhelpful (nondiagnostic or false negative) in establishing the patient’s diagnosis.
