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.

Fabric-based endocervical curettage may significantly decrease inadequate and limited endocervical curettage specimens.
