Risks and benefits of culdoscopic female sterilization.
This paper reviews the risks and benefits of the culdoscopic approach to female sterilization in an alnalysis of 2153 culdoscopic sterilization procedures performed at 11 centers in nine countries. Inability to occlude the tubes as planned was reported for approximately 6.0% of the cases including 1.4% in which one or both tubes could not be occluded by any technique. Surgical difficulties were reported for about 13.0% of the procedures, and surgical complications, of which the most frequent was torn or bleeding tubes, occurred in 2.0% of the cases. Pregnancy rates were significantly higher for patients whose tubes were occluded by tantalum clips (7.7 per 100 women at 12 months), indicating that this is not the preferred technique of tubal occlusion; the 12-month life table pregnancy rates were 0.1 per 100 women for tubal ring and 0.0 for Pomeroy and fimbriectomy. Comparison of these data with similar pooled data on laparoscopy and minilaparotomy indicates that culdoscopy is associated with greater technical difficulty and morbidity. Thus, abdominal procedures will continue to be preferred for use in most large-scale programs.
