Using Lamicel to expose high cervical lesions during colposcopic examinations.

Area of Science:

• Gynecology
• Cervical Pathology
• Colposcopy

Background:

• Abnormal cervical cytology necessitates further investigation, often including colposcopy.
• Unsatisfactory colposcopic examinations, where the entire squamocolumnar junction is not visualized, pose a diagnostic challenge.
• The squamocolumnar junction is critical for identifying cervical abnormalities.

Purpose of the Study:

• To evaluate the efficacy of Lamicel, a cervical sponge, in improving visualization of the transformation zone during colposcopy.
• To determine if Lamicel can help visualize the entire squamocolumnar junction in cases of unsatisfactory colposcopy.
• To assess the impact of improved visualization on the need for cervical cone biopsy.

Main Methods:

• Lamicel sponges were intracervically placed in 41 patients with abnormal cervical cytology and unsatisfactory colposcopy.
• The sponge was designed to soften, dilate, and efface the cervix.
• Colposcopy was repeated after 3-4 hours following sponge removal.

Main Results:

• In 29 out of 41 patients (70.7%), Lamicel facilitated full visualization of the lesion and the squamocolumnar junction.
• Improved visualization led to 25 of these patients being spared a cone biopsy.
• The Lamicel sponge demonstrated effectiveness in exposing the entire transformation zone.

Conclusions:

• Lamicel is a valuable tool for enhancing colposcopic visualization of the cervical transformation zone.
• Utilizing Lamicel can reduce the rate of unnecessary cone biopsies in patients with abnormal cervical cytology.
• This method offers a less invasive approach to managing challenging colposcopic examinations.
