Pain and cramping associated with cryosurgery

Area of Science:

• Gynecology
• Surgical Procedures

Background:

• Cervical intraepithelial neoplasia (CIN) is treated using various cryosurgery techniques.
• Patient-reported pain and cramping are important outcomes in cryosurgery.

Purpose of the Study:

• To evaluate and compare patient-perceived pain and cramping across four distinct cryosurgery methods for CIN.

Main Methods:

• A prospective trial involving 70 women compared four cryosurgery techniques: 2-minute double freeze, 3-minute double freeze, 5-minute single freeze, and 5-minute double freeze.
• Pain and cramping were assessed immediately post-procedure by a trained interviewer.
• Patient demographics, lesion severity, and NSAID pretreatment were analyzed.

Main Results:

• Median pain scores were 4, 3, 3, and 7 for the 2-minute double, 3-minute double, 5-minute single, and 5-minute double freeze, respectively.
• Median cramping scores were 0, 0, 0, and 7 for the respective procedures.
• The 5-minute double freeze resulted in significantly higher pain (P = .012) and cramping (P < .001) scores compared to other methods.

Conclusions:

• Cryosurgery for CIN is associated with pain and cramping.
• The 5-minute double freeze technique is linked to the highest levels of perceived pain and cramping.
• Nonsteroidal anti-inflammatory drug (NSAID) pretreatment did not mitigate pain or cramping during the 5-minute double freeze procedure.
