Patients and methods
Thirty-four patients (21 women, 13 men: mean age 58 years, range 27-73 years) presenting with idiopathic abdominal masses were evaluated by EUS-FNA at 5 tertiary referral centers. Procedure reports, results of the cytopathologic evaluation of the specimens, and related medical records for EUS-FNA procedures performed between 1996 and 1998 were systematically reviewed at the participating centers, and summaries were provided to the data collection center (Milwaukee). All patients were referred
Results
Final diagnoses by disease category were infectious (5 patients), benign/inflammatory (6), and malignant (23) abdominal masses. Inclusive of all 3 categories, EUS-FNA resulted in a correct diagnosis in 29 of 34 patients (85%). With reference to the 3 specific disease categories EUS and FNA provided an accurate cytologic diagnosis in 4 of 5 patients with infectious (80%), 4 of 6 with benign/inflammatory (67%), and 21 of 23 patients with malignant masses (91%). Diagnosis in the first 2 categories
Discussion
Intra-abdominal masses arise from intraperitoneal (e.g., liver, spleen, stomach) and retroperitoneal (kidney, pancreas, spine, muscular elements) viscera. Before the advent of EUS, US-guided and CT-guided percutaneous tissue sampling were used for diagnosis, although in many cases laparotomy was still required.2 Many pathologic processes can lead to formation of an intra-abdominal mass and accurate noninvasive diagnosis is difficult because the origin or precise location of the mass is often
