Loop electrosurgical excision procedure with or without intraoperative colposcopy: a randomized trial

Area of Science:

• Gynecology
• Surgical Oncology
• Colposcopy

Background:

• Loop electrosurgical excision procedure (LEEP) is standard for cervical dysplasia.
• LEEP under colposcopic guidance is recommended to reduce adverse pregnancy outcomes.
• Evidence from randomized trials supporting this recommendation is lacking.

Purpose of the Study:

• To evaluate the benefits of performing loop electrosurgical excision procedure (LEEP) under colposcopic guidance in women diagnosed with cervical dysplasia.

Main Methods:

• A prospective, randomized trial comparing standard LEEP with LEEP performed under direct colposcopic vision.
• Primary endpoint: resected cone mass. Secondary endpoints included margin status, specimen fragmentation, procedure time, hemostasis time, blood loss, and complications.
• 182 women were randomized (93 standard LEEP, 89 LEEP with colposcopy).

Main Results:

• LEEP with colposcopic guidance yielded significantly smaller resected cone specimens (median 1.86g vs. 2.37g, P=.006).
• No significant differences were observed in margin status, fragmentation, procedure time, hemostasis, blood loss, or complication rates between the groups.
• Multivariate analysis indicated that study group allocation and parity independently influenced resected cone mass.

Conclusions:

• Loop electrosurgical excision procedure performed with intraoperative colposcopy guidance results in significantly smaller cone specimens.
• This approach does not compromise the status of the resection margins.
• Intraoperative colposcopy may offer an advantage in tissue management during LEEP for cervical dysplasia.
