Five year evaluation of intraoperative pathology consultations in a university hospital

Abstract

Objectives: Intraoperative pathology consultation (IOPC) is one of the most important and most difficult processes of pathology practice and the review of the results is accepted as a quality-control method in pathology laboratories. Because of the obligation of being made under stress and quickly, IOPC process is an error-prone method every time.Methods: In this study, the IOPC cases that were examined in Dicle University Medical Faculty between the years of 2007-2012 are reviewed.Results: 1758 (97.08%) of 1811 IOPC cases were diagnosed correctly. Of 53 cases that were diagnosed wrongly, 39 (2.15%) and 14 (0.77%) were diagnosed as wrong negative and wrong positive respectively. In our series it is detected that, of 53 wrongly diagnosed cases, the wrong diagnose was related to comment error in 35, to macroscopic sampling error in 15, and to technical error in 3. In the tissues of IOPC cases, the ovary materials constituted the first frequency. The 8 of 449 evaluated ovary cases were diagnosed wrongly and when 27 cases in which the diagnose was left to paraffin sections were excluded, the accuracy rate was determined as 98.11%. Conclusion:In our series, this rate relating to IOPC of ovary tissues seems as the highest accuracy rate in the literature.

The Accuracy of Frozen Section in the Diagnosis of Malignant Adnexal Masses

“…Frozen section is a very useful method for diagnosing the behavior of the tumor intra-operatively as benign, borderline or malignant, with a higher accuracy. Most studies have reported the accuracy of frozen section from 90% to 97% [3][4][5][6][7]. In the present study, the overall accuracy is 97.9%.…”
