Histopathologic and Preneoplastic Changes in Tubal Ligation Materials

Abstract

Abstract
 Objectives
 To investigate histopathological changes and serous carcinoma precursors such as secretory cell outgrowths (SCOUTs) and p53 signature in bilateral tubal ligation (BTL) materials performed during cesarean section (S/C).
 Materials and Methods
 138 patients who underwent S/C and tubal sterilization (TS) between October 2020 and May 2021 at Konya City Hospital. Patients’ data were obtained from the haospital’s system. All data andd findings were investigated and statistically evaluated.
 Results
 The mean age was 34.62 years (22 - 44), the mean gravity was 4.89 (2-15) and the mean parity was 3.46 (1-10). 5.79% SCOUT, 7.24% atypia and 9.42% p53 signatures were observed. Significant correlations were shown between epithelial cell lineage and age and between KI-67, SCOUT, and gravity, between KI-67 results and gravity and parity, and between P53 score and age. 
 Conclusion
 TS is a common, safe, and effective method worldwide. Today, BTL is increasing along with increasing S/C ratios. In addition to the reduced risk of ovarian cancers with ligation alone, precursor lesions such as hyperplasia, SCOUT, p53 signature, and STIL/ Serous tubal intraepithelial carcinoma (STIC) are encountered in the ampulla materials obtained. Considering the low rates of re-anastomosis, tubal excision may be recommended instead of ligation in women of relatively higher gravity and age.
