  1. Endoscopic ultrasound guided fine needle aspiration biopsy : a large single centre experience.

    Article - En anglais

    Background-Endoscopic ultrasound guided fine needle aspiration biopsy (EUS-FNA) is a recent innovation in the evaluation of gastrointestinal and pulmonary malignancies.

    Aims-To review the experience with EUS-FNA of a large single centre.

    Methods-333 consecutive patients underwent EUS-FNA.

    Follow up data were available on 327 lesions in 317 patients, including 160 lymph nodes, 144 pancreatic lesions, 15 extraintestinal masses, and eight intramural tumours.

    Results

    A primary diagnosis of malignancy was obtained by EUS-FNA in 62% of patients with clinically suspicious lesions.

    The overall accuracy of EUS-FNA for the diagnosis of malignancy was 86%, with sensitivity of 84% and specificity of 96%. With respect to lesion types, the sensitivity, specificity, and accuracy were 85%, 100%, and 89% for lymph nodes ; 82%, 100%, and 85% for pancreatic lesions ; 88%, 100%, and 90% for perirectal masses ; and 50%, 25%, and 38% for intramural lesions, respectively.

    Compared with size and sonographic criteria, EUS-FNA in the evaluation of lymph nodes provided superior accuracy and specificity, without compromising sensitivity.

    Inadequate specimens were obtained from only six patients, including 3/5 with stromal tumors.

    Only one complication occurred.

    Conclusions-EUS-FNA is safe and can readily obtain tissue specimens adequate for cytopathological diagnoses.

    Compared with size and sonographic criteria, it is a superior modality for the detection of nodal metastases. (...)
