“Best practices in risk reducing bilateral salpingo-oophorectomy: the influence of surgical specialty”

Abstract

Background

Risk-reducing bilateral salpingo-oophorectomy (RRBSO) increases survival in patients at high risk of developing ovarian cancer. While many general gynecologists perform this procedure, some argue it should be performed exclusively by specialists. In this retrospective observational study, we identified how often optimal techniques were used and whether surgeons' training impacted implementation.

Methods

We used the ACOG guidelines highlighting various aspects of the procedure to determine which elements were consistent with best practices to maximize surgical prophylaxis. All cases of RRBSO from 2006 to 2010 were identified. We abstracted data from the operative and pathology reports to review the techniques employed. Fisher's exact test and chi-square were utilized to compare differences between groups (InStat, La Jolla, CA).

Results

Among 263 RRBSOs, 22 were performed by general gynecologists and 241 by gynecologic oncologists. Gynecologic oncologists were more likely to perform pelvic washings—217/241 vs. 10/22 (p < .0001). They were more likely to include a description of the upper abdomen—220/241 vs. 12/22 (p < .0001). Oncologists were more likely to utilize a retroperitoneal approach to skeletonize the infundibulopelvic ligaments—157/241 vs. 3/22 (p < .0001). When operations were performed by oncologists, the specimens were more often completely sectioned—217/241 vs. 16/22 (p = .003). The use of a retroperitoneal approach among gynecologic oncologists increased over the study period (chi-square for trend, p < .0001). There was no visible trend in performance improvement in any other area when looking at either group.

Conclusion

Gynecologic oncologists are more likely to adhere to best practice techniques when performing RRBSO, though there was room for improvement for both groups.
