Abstract

AIM: To investigate the distribution of tubal endometriosis (EM) in the right and left sides and four parts of the fallopian tube. METHODS: A retrospective, cross-sectional study was conducted on patients with tubal EM at the Fourth Affiliated Hospital of Guangxi Medical University from October 2011 to September 2021. Chi-square and binomial tests were used for analysis. RESULTS: Thirty-four patients (53.97%) had tubal resection due to EM (EM group). Twenty-nine patients (46.03%) had tubal resection due to non-EM (non-EM group). Thirty-two patients (50.80%) had left fallopian tube EM, 21 (33.33%) had right fallopian tube EM, and 10 (15.87%) had bilateral fallopian tube EM, with significant differences among them (p = 0.000). In the EM group, 15 patients (44.12%) had left fallopian tube EM, 13 (38.23%) had right fallopian tube EM, and 6 (17.65%) had bilateral fallopian tube EM (p = 0.052). In the non-EM group, statistically different (p = 0.001) diagnoses of left fallopian tube EM, right fallopian tube EM, and bilateral fallopian tube EM were 17 (58.62%), 8 (27.59%), and 4 (13.79%), respectively. In the EM group, 18 patients (52.94%) were in the ampullary region; 16 (47.06%) were in the nonampullary region (p = 0.864). In the non-EM group, 22 cases (75.86%) were in the ampullary region and 7 (24.14%) were in the nonampullary region, with a significant difference between them (p = 0.008). CONCLUSIONS: The incidence of left fallopian tube EM was higher than that of right and bilateral fallopian tube EM. The incidence of tubal ampullary EM was higher than that of nonampullary region.
