|Fine Needle Aspiration Biopsy with Menghini tip: A brand-new technique for obtaining histological samples of small lesions with difficult anatomical approach|
Methods and materials
A retrospective study of Fine Needle Aspiration Biopsy (FNAB) technique was performed in 49 patients of our center (Hospital Vall d'Hebron of Barcelona), obtaining a total of 52 samples over a two-year period (February 2016 to February 2018). In 3 of the patients the technique was performed in 2 different locations.
Two ultrasound Systems were used: Siemens Acuson S2000 and Esaote MyLab Twice and 20G Hepashot needles (Fig. 7)
The different reasons for performing FNAB in these patients were:
● Small injuries
● Injuries in hard-to-reach locations
● Injuries near vital structures.
● Prior realization of non-diagnostic FNAB
A frequency analysis carried out using the following variables:
● Baseline characteristics of the patient (sex and age).
● Anatomical location of the lesion.
● Size of the lesion (measured in millimeters).
● Diagnostic suspicion (in the case of primary lesions) or nature of the primary lesions (in the case of suspected implantation or dissemination).
● Etiological diagnosis of the lesions.
● Diagnostic efficacy of the technique by analyzing the results of pathological anatomy (sample sufficient for diagnosis or not).
● Immediate or late complications secondary to the performance of the technique.
