Loop diathermy cone biopsy offers a quick, simple, and economical method for excising cervical intraepithelial neoplasia (CIN) and microinvasive carcinoma. This technique provides good histologic specimens with low short-term morbidity.

Area of Science:

  • Gynecology
  • Surgical Oncology
  • Pathology

Background:

  • Cervical intraepithelial neoplasia (CIN) and microinvasive cervical carcinoma require effective treatment.
  • Cone biopsy is a standard procedure for diagnosing and treating these conditions.

Purpose of the Study:

  • To present and evaluate a technique for cone biopsy using loop diathermy.
  • To assess the efficacy, safety, and histologic quality of specimens obtained via loop diathermy cone biopsy.

Main Methods:

  • A loop diathermy device, connected to an electrosurgical unit, was used for cone biopsies.
  • The study analyzed data from the first 50 cases, including patient demographics, diagnoses, cone dimensions, and complication rates.

Main Results:

  • The mean patient age was 41.6 years.
  • Histopathological findings included 72% cervical intraepithelial neoplasia III and 6% microinvasive carcinoma.
  • Mean cone length was 20.2 mm, mean weight was 3.9 g, and incomplete excision was reported in 10% of cases.
  • No major complications occurred; minor complications were observed in 8% of patients.

Conclusions:

  • Loop diathermy cone biopsy is a quick, simple, and cost-effective procedure.
  • It yields adequate histologic specimens with a low incidence of short-term morbidity.
  • This technique is suitable for managing CIN and early-stage cervical cancer.
