Abstract

Objective: To determine the incidence of fallopian tube endometriosis in patients undergoing laparoscopic surgery with a preoperative diagnosis of endometriosis, pelvic pain, infertility, or cystic adnexal mass.

Design: Retrospective cross-sectional study.

Setting: Gynecologic oncology and minimally invasive surgery practice.

Patient(s): All patients who underwent surgery for endometriosis from July 2015 to June 2018 were included. Exclusion criteria were age ≥55 years, diagnosis of cancer, laparotomy, previous bilateral salpingectomy, and preoperative diagnosis other than endometriosis, pelvic pain, infertility, or cystic adnexal mass.

Intervention(s): Subjects were divided by those who did and those who did not have a salpingectomy at the time of surgery.

Main outcome measure(s): Diagnosis of tubal endometriosis was based on macroscopic evidence of endometrial implants on the fallopian tube(s) noted within the operative report and microscopic evidence of endometriosis noted within the pathology report.

Result(s): A total of 444 surgeries were performed and 185 met the study criteria. Among those, 153 (82.7%) had histologically diagnosed endometriosis within the abdominopelvic cavity. The incidence of tubal endometriosis was 11%-12% macroscopically and 42.5% microscopically after salpingectomy. Patients with tubal endometriosis were more likely to have severe disease.

Conclusion(s): Among patients with endometriosis, the incidence of microscopic tubal endometriosis was significantly greater than that of macroscopic disease.

Keywords: Endometriosis; fallopian tube; infertility; laparoscopy; salpingectomy.
