Study of histopathology reports of loop electrosurgical excision procedure of cervical transformation zone and their correlation with preprocedural cervical biopsy and/or cytology: An audit.

Introduction: Loop electrosurgical procedure of the transformation zone of the cervix (LEEP) is the preferred method for many investigators for early detection and treatment of high grade intraepithelial neoplasia(HGCIN). Histopathology reports of LEEP should contain information about the diagnosis, presence or absence of neoplasia ( with its grade) and comment on excison margins.

Aim: Our aim was to study LEEP reports for its contents and to see their correlation with preprocudure histology and/or cytology report.

Results: Between 2011 and 2017, 44 LEEP reports were archived and studied for their contents from our records. Slides were not reviewed. Mean age was 47.66 years (median 47 years). Forty two (( 95.45%) reports mentioned that all the tissue was examined. Deep cut examination was mentioned in 17/44 cases (38.64%). The concordance rate between LEEP and preprocudure histology and /or cytology for CIN II plus diagnosis is 65.9%. A strict definition is used. If, however, diagnoses between inflammation and CIN I, ASC-H and inflammation, and ASC-H and CIN I are considered non discordant, then the concordance rate rises to 72.7 %. The breakup of discordant cases is given.

Conclusion: Literature shows wide range of concordance due to variable definitions and variety of reasons; possible reasons are discussed.
