Summary
Fimbriectomy, a sterilization procedure, may lead to acquired tuboperitoneal fistulas, likely from catgut ligatures. Resection of the infundibulum during this procedure may offer questionable benefits.
Area of Science:
- Reproductive Medicine
- Surgical Pathology
Background:
- Bilateral fimbriectomies were performed between 1970-1973 for sterilization.
- Seven pregnancies occurred by 1974 in patients who underwent the procedure.
Purpose of the Study:
- To investigate the cause of post-fimbriectomy pregnancies.
- To compare acquired tuboperitoneal fistulas with congenital ones.
- To evaluate the technique of fimbriectomy.
Main Methods:
- Morphological examination of four unilateral tuboperitoneal fistulas found in patients with post-fimbriectomy pregnancies.
- Comparison of these fistulas with congenital tuboperitoneal fistulas.
Main Results:
- All four examined fistulas were determined to be acquired.
- The acquired fistulas were likely caused by catgut ligatures used for ampullary ligation.
- Hydrosalpinx was frequently observed after fimbriectomy.
Conclusions:
- The use of catgut ligatures in fimbriectomy may lead to acquired tuboperitoneal fistulas.
- Resecting the infundibulum during fimbriectomy using the three-ligature technique appears to have questionable advantages.
