Abstract

BACKGROUND

• Diagnostic endoscopic biopsy of intra-abdominal lesions may be performed prior to surgical resections.

• Endoscopic ultrasound-guided fine needle aspiration of intra-abdominal lymph nodes may also be performed to:

• Yield more information

• Allow for more accurate staging

• We evaluate the additional staging information concurrent fine needle aspiration of intra-abdominal lymph nodes provided

DESIGN

• We included all patients at our institution from January 1, 2000 to March 30, 2015 who, during the same endoscopic procedure, had:

• Endoscopic ultrasound guided fine needle aspiration of an intra-abdominal lymph node AND

• Endoscopic ultrasound guided fine needle aspiration OR a surgical biopsy of an intraabdominal lesion

• We excluded all patients for whom the final diagnosis was lympho-proliferative

• Primary lesions were:
