RESUMO
OBJECTIVES: To determine the incidence of incomplete ovarian removal during gynecologic surgery and correlate the risk of inadequate removal with the procedure chosen. METHODS: This is a prospective observational study. Ovaries received during a 4-month period in the participating institutions were independently histologically evaluated. Gross inspection of the ovarian capsule, infundibulopelvic ligament, hilum and utero-ovarian ligament was assessed. Grossly close margins were confirmed histopathologically. Any margin with histologically confirmed ovarian tissue at the margin was interpreted as incompletely removed. Details of each surgical procedure were recorded for comparison. RESULTS: Ovaries (n=174) from 94 patients were collected and 155 were evaluable. The overall incidence of incomplete ovarian removal was 6.5%. Of the 125 ovaries removed abdominally, 23 were laparoscopically assisted and 7 were vaginal; inadequate removal was documented in 5%, 9% and 29%, respectively (P=0.04). There was no relationship of inadequate resection by underlying pathologic diagnosis (P=0.25) or by institution (4.6% university hospital vs. 8.8% community hospital; P=0.29). CONCLUSIONS: Incomplete ovarian removal occurs and is related to surgical approach. A larger study is warranted to evaluate the role of pelvic pathology or surgeon experience as a risk for incomplete oophorectomy.
