Comparison of Tissue Yield Using Frictional Fabric Brush Versus Sharp Curettage For Endocervical Curettage.

ABSTRACT

OBJECTIVE: The aim of the study was to evaluate and compare the diagnostic yield of conventional endocervical curettage (ECC) with fabric-based ECC in a consistent physician group. MATERIALS AND METHODS: This is a retrospective case-control study of patients who underwent ECC both before and after introduction of a fabric-based ECC device. Histologic examination of curettings was categorized as satisfactory, limited, or inadequate. The Kruskall-Wallis test was used to compare proportions of gross descriptions and final diagnoses between groups. RESULTS: Between January 2010 and July 2011, 9234 ECCs were performed using conventional ECC technique. From September 2011 to October 2013, 774 ECCs were performed with the fabric-based ECC. Using the conventional ECC technique, 7809 (84.6%) of specimens were satisfactory, 1037 (11.2%) were limited, and 388 (4.2%) were inadequate and repeat biopsy was recommended. With fabric ECC, 705 (91.1%) of specimens were satisfactory, 64 (8.3%) were limited, and 5 (0.6%) were inadequate, and repeat biopsy was recommended. There were significantly fewer inadequate specimens with the fabric-based ECC (4.2% vs 0.6%, p < .001). CONCLUSIONS: Fabric-based ECC may significantly decrease inadequate and limited ECC specimens.
