Abstract

Eighty consecutive gynecologic specimens obtained with the Cavitron Ultrasonic Surgical Aspirator (CUSA) were evaluated pathologically. Fifty specimens were obtained during intraabdominal tumor debulking and thirty resulted from ablation of lower genital tract lesions. In 98% of intraabdominal specimens and in 93% of patients with a history of lower genital tract lesions, the CUSA material permitted an accurate diagnosis. Although artifacts related to cellular thermal injury were ubiquitous, nearly all cases were interpretable with a combination of cytologic (smear, Cytospin, Millipore filter) and histologic (cell block) preparations. Squamous intraepithelial lesions (SILs) of the lower genital tract were better preserved in cell block preparations, whereas intraabdominal adenocarcinomas were readily diagnosed by both cytologic and histologic techniques. Accurate grading of SILs and exclusion of invasion were difficult in some cell blocks due to the fragmented and superficial nature of the samples. Cytologic preparations of lower genital tract lesions often consisted of thick uninterpretable fragments and degenerated single cells that contributed little to the evaluation of SILs. We conclude that examination of CUSA specimens confirmed the surgical removal of pathologic tissue in 96% of cases, but an exact diagnosis Of SILs Was not possible in all Cases.
