Persistent tubal epithelium in ovaries after salpingectomy

The aim of this study is to evaluate the presence of residual tubal tissue and endosalpingiosis on the ovarian surface after salpingectomy. A total of 105 ovarian tissues of 54 patients who underwent abdominal total hysterectomy with bilateral or unilateral salpingo-oophorectomy for benign indications between January 2019 and December 2019 were included in the study. Salpingectomy was performed prior to oophorectomy in all patients. The adhesion grade score was calculated for each case. Persistent tubal epithelium was found in 16 (29.6%) of the patients. There was a significant difference in adhesion scores between the persistent tubal epithelium negative and persistent tubal epithelium - positive patients (p = 0.041). In conclusion, permanent tubal epithelium may remain in the ovaries after salpingectomy. Persistent tubal epithelium is more common in cases with intra-abdominal adhesions. Opportunistic and risk-reducing salpingectomy is effective to prevent ovarian cancer, although it is not a definitive solution.
