Diagnosis and treatment of tubal endometriosis in women undergoing laparoscopy: A case series from a single hospital

BACKGROUND: Tubal endometriosis (TEM) is a category of pelvic endometriosis (EM) that is characterized by ectopic endometrial glands and/or stroma within any part of the fallopian tube. The fallopian tubes may be a partial source of ovarian endometriosis (OEM). TEM is difficult to diagnose during surgery and is usually detected by pathology after surgery. AIM: To provide a clinical basis for the diagnosis and treatment of TEM. METHODS: In this study, the data of 30 patients who underwent laparoscopic salpingectomy due to various gynecological diseases and had pathological confirmation of TEM at our hospital were retrospectively analyzed, and the clinical basis for the diagnosis and treatment of TEM was evaluated. RESULTS: Among 1982 surgical patients, 30 met the study criteria. Among those, 6 patients had a history of infertility, 12 patients had a history of artificial abortion, 13 patients had a history of cesarean section, 1 patient had a history of tubal ligation, 4 patients had an intrauterine device, and 22 patients had hydrosalpinx. Sixteen patients (53.33%) conceived naturally and gave birth to healthy babies. Pathology showed that only 2 patients had TEM without any other gynecological diseases, while the others all had simultaneous diseases, including 26 patients with EM at other pelvic sites. CONCLUSION: The final diagnosis of TEM depends on pathological examination since there are no specific clinical characteristics. The rate of TEM combined with EM (especially OEM) was higher than that of other gynecological diseases, which indicates that TEM is related to OEM.
