Filshie Clip Removal for Fertility Restoration
Do not remove the Filshie clips—instead, refer the patient directly to a reproductive endocrinologist or fertility specialist for tubal sterilization reversal surgery (microsurgical reanastomosis), which offers pregnancy rates of approximately 70-85% when performed by experienced surgeons.
Why Reversal Surgery, Not Simple Clip Removal
Simply removing Filshie clips does not restore tubal patency or fertility. The clips cause localized tubal damage and occlusion at the application site. Successful pregnancy restoration requires microsurgical tubal reanastomosis—reconnecting the healthy tubal segments after excising the damaged portion 1, 2.
The evidence clearly demonstrates that:
- Filshie clips are specifically designed for reversibility compared to other sterilization methods, as they cause minimal tubal destruction (approximately 4-5mm of tube) 2, 3
- Pregnancy rates after reversal surgery are highest with Filshie clips compared to other sterilization methods like electrocoagulation or silicone rings 2
- All 7 women who underwent reversal surgery in one follow-up study successfully conceived 4
The Reversal Procedure
The patient needs microsurgical tubal reanastomosis, not clip removal. This involves:
- Laparoscopic or mini-laparotomy approach
- Excision of the clip site and damaged tubal segment
- Microsurgical reconnection of healthy tubal ends
- Verification of tubal patency
Microsurgical techniques achieve significantly higher pregnancy rates and lower ectopic pregnancy rates than older macrosurgical approaches 1.
Critical Counseling Points
Before proceeding, counsel the patient on:
Success rates: Pregnancy rates of 70-85% are achievable with experienced surgeons, but success inversely correlates with the degree of initial tubal destruction 1
Alternative option: Highly effective reversible contraception (IUDs, implants) should have been discussed before the original sterilization, as these methods are "not intended to be reversible" 5. However, since sterilization has already occurred, IVF may be an alternative if reversal fails or is not feasible
Ectopic pregnancy risk: While lower with Filshie clips than electrocoagulation methods, ectopic pregnancy remains a concern after any tubal surgery 1, 2
Regret factors: The patient's age, time since sterilization, relationship stability, and reasons for reversal should be explored, as regret occurs in approximately 4% of patients 4
Common Pitfall to Avoid
Do not attempt simple laparoscopic clip removal expecting fertility restoration—this will not work. The tubal damage from clip placement requires surgical repair, not just hardware removal. The only indication for isolated clip removal is symptomatic clip migration causing chronic pain 6, 7, which is not this patient's presentation.
