Cervical conization: cold knife and laser excision in residency training.

Area of Science:

• Gynecologic Oncology
• Minimally Invasive Surgery
• Colposcopy and Cervical Pathology

Background:

• Cervical conization is a common procedure for managing cervical dysplasia.
• Both laser excision and cold knife conization are established surgical techniques.
• Resident training in these procedures requires evaluation of safety and efficacy.

Purpose of the Study:

• To compare the outcomes of laser excision versus cold knife conization performed by obstetrics and gynecology residents.
• To evaluate differences in operating time, complication rates, blood loss, and treatment success.

Main Methods:

• Retrospective review of 293 consecutive conizations performed by residents over a 2-year period.
• Patients were divided into two groups: laser excision (n=161) and cold knife conization (n=132).
• Data collected included operative time, complication rates (minor and major), blood loss, and follow-up cytology/colposcopy results.

Main Results:

• Average operating times were similar: 31 minutes for laser excision and 33 minutes for cold knife conization.
• Combined complication rates were lower for laser excision (19%) compared to cold knife (30%).
• Major complications (stenosis, bleeding) were significantly lower in the laser group (6% vs. 20%), with less blood loss (34 mL vs. 65 mL).

Conclusions:

• Laser excision and cold knife conization demonstrate comparable efficacy in treating cervical dysplasia among residents.
• Laser excision is associated with a significantly lower rate of complications and reduced blood loss.
• These findings support laser excision as a potentially safer alternative in resident training programs.
