title: A lifetable analysis of sterilization failure: data from the Profamilia Clinic, Bogota, Colombia.
abstract: Sterilization failure rates were computed using lifetable methods for sterilizations occurring between 1973 and 1982 in the Profamilia family planning clinic in Bogota, Colombia. Out of a total of nearly 45,000 sterilizations occurring during this period 503 sterilization failures were detected. Comparing methods, laparoscopy with the silastic band method had a significantly higher rate of failure, 1.5% after 5 years compared to 0.9% for laparoscopy with cautery and 0.6% for minilaparotomy.
