Design: This is a retrospective chart review study.

Setting: Two high volume tertiary health care centers

Patients or Participants: Any patient who underwent bilateral salpingectomy for sterilization in the Indiana University Health or Eskenazi Health systems between January 2018 and September 2023.

Interventions: n/a

Measurements and Main Results: 2967 patients were identified as having undergone a procedure with a CPT code that represented tubal surgery (58600, 58605, 58611, 58661, 58670). Of these patients, 1028 were identified as having undergone a bilateral salpingectomy (including laparoscopic, postpartum, or at the time of cesarean section). 186 patients were excluded because of postmenopausal status, incomplete records, or being deceased within a year of their surgery. 14 patients were excluded because they were undergoing IVF after their surgery. Of the 1028 patients who underwent bilateral salpingectomy, 3 patients reported having a positive home pregnancy test. All 3 of these patients had negative pregnancy testing in the office shortly afterwards, thus, the rate of spontaneous pregnancy after bilateral salpingectomy in our study population was 0-0.3% over a 5-year period of time.

Conclusion: Based on our data, the rate of spontaneous pregnancy after bilateral salpingectomy is 0-0.3%. This is lower than the published rate of pregnancy after all methods of sterilization of 1.33% by Peterson, et al 1996. This supports bilateral salpingectomy as a high-quality method of contraception and should encourage providers to perform salpingectomy when feasible. Future studies with a larger patient population and longer follow-up are needed to further support our findings.
