Endoscopic Ultrasound-Guided Fine Needle Aspiration Using a 22-G Needle for Hepatic Lesions: Single-Center Experience.

ABSTRACT:

Background/aims

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has been accepted as a reliable tool in diagnosing and staging intra-abdominal tumors. In this study, we aimed to investigate the performance of EUS-FNA in the evaluation of liver masses and its impact on patient management and procedure-related complications retrospectively.

Methods

Data of patients who underwent EUS-FNA biopsies due to liver masses between November 2017 and July 2018 were retrieved retrospectively. Biopsies were performed using 22-G needles. The demographics, EUS-FNA results, sensitivity and specificity of the procedure, negative predictive value, positive predictive value, and specimen sufficiency rates were assessed.

Results

A total of 25 patients (10 females) were included in the study. The mean age was 62.73±15.2 years. The mean size of the masses was 34.50±16.04 mm. The technical success rate was 88%. During the EUS-FNA procedure, each patient had only one pass with 94.45% of aspirate sufficiency rate and 86.3% of biopsy sufficiency rate. The diagnostic accuracy rate was 86.3%. There were no complications.

Conclusion

For the evaluation of liver masses, EUS-FNA using a 22-G needle with even one pass had high aspiration and biopsy success rates accompanied with high diagnostic accuracy rates.

Project description:Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is an effective technique for qualitative diagnosis of space occupying lesions in and around the wall of the digestive tract. At present, there are many studies on EUS-FNA via the upper gastrointestinal route, while there are few studies on EUS-FNA via the lower gastrointestinal route, especially for Chinese patients with pelvic mass. Therefore, this study sought to evaluate the value of transrectal EUS-FNA in the qualitative diagnosis of pelvic masses in Chinese patients. The clinical data of 35 patients with pelvic masses who underwent EUS-FNA at our hospital were collected from September 2014 to December 2021. Among these patients, 10 underwent surgical treatment after EUS-FNA, and a diagnosis was made based on a pathologic evaluation. The EUS-FNA biopsy results were compared to the final diagnostic results to calculate the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of EUS-FNA in the diagnosis of malignant pelvic mass. For the 10 patients who underwent surgery, the final diagnoses were based on the pathologic findings of surgical specimens, and for the 25 patients who did not undergo surgery, the final diagnoses were based on the malignant pathological results of EUS-FNA or clinical follow-up results. Among the 35 patients, 12 had benign lesions, including pelvic abscesses, cysts, and inflammatory masses, and 23 had malignant lesions, including mesenchymal tumors, leiomyosarcomas, teratomas, and malignant tumors with pelvic metastases. There were no complications resulting from the biopsy punctures. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EUS-FNAs for the diagnosis of malignant pelvic masses were 91.3% (21/23), 100.0% (12/12), 100.0% (21/21), 85.7% (12/14), and 94.3% (33/35), respectively. EUS-FNA is a safe and effective method for the qualitative diagnosis of pelvic masses, and has good clinical application value.

Project description:AimThe aim of this study was to compare the diagnostic adequacy of computed tomography (CT)-ultrasound (US) fusion image-guided fine needle aspiration (FNA) and US-guided FNA in patients with suspected hepatic metastases.MethodsThirty consecutive patients of either sex with known or unknown primary malignancy suspected of having liver metastases on both US and CT, whose multiphasic contrast-enhanced computed tomography was performed using a 64-slice or a higher slice CT scanner, and who were referred for percutaneous FNA were included in this prospective study approved by the institutional review board of the study institute. CT-ultrasound fusion image-guided FNA of the largest lesion using electromagnetic tracking and with freehand ultrasound-guided FNA were performed in the same sitting. Value of fitness, which is a rough estimate of how well the fusion has been achieved, was recorded. Diagnostic adequacy of smears was assessed by a scoring system based on cellular material, background blood/clot, degree of cellular degeneration or trauma, and retention of architecture.ResultsThe size of the lesions ranged from 1 to 10 cm, and the depth of location of the lesions ranged from 1.4 to 9.3 cm. The fusion fitness values ranged from 1.2 to 10 mm. The scores of the smears did not correlate with lesion size, depth of location, and fusion fitness value. Diagnostic adequacy was seen in 90% and 93.3% of lesions sampled by fusion image guidance and ultrasound guidance, respectively (p = 0.655). All the lesions that yielded inadequate smears by fusion guidance were deep-seated lesions (>5 cm). All the lesions that yielded inadequate smears by ultrasound guidance were small lesions (<3 cm). No complications were encountered in any of the patients.ConclusionFusion image-guided FNA is a safe procedure with a high diagnostic adequacy rate. Fusion image-guided FNA is not better than US-guided FNA for conspicuous hepatic lesions; however, it may be useful in inconspicuous lesions.
