Loop electrosurgical excision and cold-knife conization show similar effectiveness for treating cervical dysplasia and microinvasive cervical carcinoma, with comparable complication and clearance rates.

Area of Science:

  • Gynecology
  • Oncology
  • Surgical Procedures

Background:

  • Cervical dysplasia and microinvasive cervical carcinoma require conization for diagnosis and treatment.
  • Both cold-knife conization and loop electrosurgical excision procedure (LEEP) are utilized for this purpose.
  • Comparative data on their diagnostic ability and treatment efficacy is essential for clinical decision-making.

Purpose of the Study:

  • To compare the diagnostic accuracy of cold-knife conization versus loop electrosurgical excision procedure.
  • To evaluate and compare the treatment efficacy of both conization methods.
  • To assess complication rates and therapeutic outcomes between the two procedures.

Main Methods:

  • A prospective randomized clinical trial was conducted with 180 women requiring conization.

  • Participants were randomized to receive either cold-knife conization or loop electrosurgical excision procedure.
  • Key outcomes assessed included complication rates, lesion clearance, and therapeutic results.

    • Main Results:

    • No statistically significant differences were observed in complication rates between cold-knife conization and loop electrosurgical excision (P = 1.00).
    • The rate of lesion clearance was comparable between the two groups (P = .18).
    • Disease recurrence rates also showed no significant difference (P = .13), with mean follow-up periods of 11.2 and 10.4 months, respectively.

    Conclusions:

    • Cold-knife conization and loop electrosurgical excision procedure provide similar diagnostic results.
    • Both methods demonstrate comparable therapeutic efficacy in managing cervical dysplasia and microinvasive cervical carcinoma.
    • The choice between cold-knife conization and loop electrosurgical excision procedure can be based on other clinical factors, as outcomes are similar.
