Opportunistic salpingectomy: Is surgical completeness achieved? Insights from the QOS study

Area of Science:

• Gynecologic Oncology
• Surgical Pathology

Background:

• Opportunistic salpingectomy is increasingly performed for ovarian cancer risk reduction.
• Complete removal of the fallopian tube is essential for maximizing this benefit.
• Residual fimbrial tissue may compromise the efficacy of salpingectomy.

Purpose of the Study:

• To assess the completeness of opportunistic salpingectomy.
• To determine the incidence of residual fimbrial tissue after adnexectomy.
• To evaluate factors influencing the completeness of salpingectomy.

Main Methods:

• Prospective enrollment of patients undergoing gynecological surgery with adnexectomy.
• Two-step adnexectomy: salpingectomy followed by oophorectomy.
• Pathological assessment using the Sectioning and Extensively Examining the Fimbria (SEE-FIM) protocol or a modified version.

Main Results:

• 201 adnexa from 115 patients were analyzed.
• Residual microscopic fimbrial tissue was identified in 7.4% of adnexa.
• No serous tubal intraepithelial carcinoma (STIC) lesions were detected.

Conclusions:

• Opportunistic salpingectomy was surgically complete in nearly 90% of cases.
• Residual fimbrial tissue presence was unpredictable by clinical or surgical factors.
• The clinical impact of remnant fimbrial tissue on ovarian cancer risk reduction requires further investigation.
