During a 23-month period, 59 patients were referred for ultrasound (US)-guided fine-needle aspiration biopsy (FNAB) of the thyroid gland because of inadequate orthodox (office) FNAB, a clinically ...small lesion, or an occult lesion. Seventy percent of the group (41 patients) was referred for surgery, which revealed cancer in 37% of patients, adenoma in 19%, and benign disease in 44%. US-guided FNAB yielded false-positive reports in 0% of patients, false-negative reports in 5% to 12%, and inadequate aspirates in 32%. The US-guided FNAB technique had a sensitivity of 60% to 90%, a specificity of 100%, a positive predictive value of 100%, a negative predictive value of 80%, and an accuracy of 85%. US-guided FNAB provides cytologic information in 60% of patients in whom a diagnosis cannot be established by orthodox (office) means, thus enhancing the diagnostic ability of clinicians who can recommend a treatment program with confidence.

Twenty-five patients with implantable cardioverter defibrillators (ICDs) implanted intrathoracically (group I) were compared with 25 patients who underwent implant using the nonthoracotomy approach ...(group II). All systems were implanted by the same medical team, in the same high volume implanting center. Indications for implantation were comparable in both groups. Patient characteristics were not statistically different with the exception of age (66-group I vs 71-group II; P < 0.05). Although left ventricular ejection fractions appeared to differ (32% vs 37%, respectively), this difference was not statistically significant (P = 0.06). ICD models used in group I were: Ventritex Cadence (16), Telectronics Guardian 4211 (2), Medtronic PCD (7); in group II they were: Ventritex Cadence (15), Guardian 4211 (2), and CPI 1600 (1). Total length of hospital stay was 16 +/- 6 days for group I versus 12 +/- 5 for group II (P < 0.05). Number of postoperative days in an intensive care unit was 3.2 +/- 2.8 for group I versus 0.5 +/- 0.6 for group II (P < 0.0001). Postoperative length of stay was 8.2 +/- 3.1 for group I versus 5.7 +/- 4.4 for group II (P < 0.001). Mean total hospital charges for the entire length of stay were $72,918 +/- $26,770 in group I versus $55,031 +/- $42,870 in group II, representing a mean reduction of 21% in global costs for group II patients. These data confirm that nonthoracotomy ICD implantation in an experienced center is associated with significantly shorter hospital stays, a virtual elimination of the need for postoperative intensive care, and globally lower total hospital costs. In addition, the presence of a statistically older population in group II does not negate these beneficial effects.
