Trial of new cervical spatula

Area of Science:

• Gynecologic pathology
• Cervical cytology screening

Background:

• Cervical cancer screening relies on accurate collection of cervical epithelium.
• Various sampling devices, including the Armovical and Ayre's spatulae, are used for cytological sample collection.

Purpose of the Study:

• To compare the efficacy of the Armovical spatula versus Ayre's spatula in sampling endocervical epithelium.
• To evaluate the impact of sampling frequency on the detection of epithelial atypia.

Main Methods:

• A comparative trial was conducted using the Armovical and Ayre's spatulae for cervical sampling.
• Cervical smears were analyzed for the presence of endocervical epithelium and epithelial atypia.
• The study involved comparing single versus double sampling per patient attendance.

Main Results:

• The Armovical spatula demonstrated significantly better performance in sampling endocervical epithelium compared to Ayre's spatula.
• No significant difference was observed between the two spatulae in detecting epithelial atypia.
• A higher incidence of atypical smears was recorded when the cervix was sampled twice during each patient visit, compared to single sampling.

Conclusions:

• The Armovical spatula is a more effective tool for obtaining endocervical samples than Ayre's spatula.
• Increased sampling frequency (twice per visit) elevates the detection rate of cervical atypia, potentially impacting screening protocols.
