  • Title: 1979 AAGL membership survey.
    Author: Phillips JM, Hulka JF, Hulka B, Corson SL.
    Journal: J Reprod Med; 1981 Oct; 26(10):529-33. PubMed ID: 6458699.
    Abstract:
    Responses from 1452 of 3827 members of the American Association of Gynecologic Laparoscopists (AAGL) surveyed in 1979 were compared with a 1976 AAGL survey to determine U.S. trends in laparoscopy. Responses showed that from 1976-1979 use of unipolar coagulation decreased from 63% to 30%, bipolar coagulation use increased from 20% to 43%, ring use increased from 16% to 24%, and clip use increased from 1% to 3%. Bipolar coagulation will probably completely replace the unipolar method because of greater safety, i.e., avoidance of a high voltage current needing to seek ground through the body. The 1979 data for ectopic pregnancies following sterilization could not be compared with 1976, but the 1979 data show that the rate of ectopic to total pregnancies exceeded 40% for each of the more destructive methods (both unipolar coagulation methods and bipolar, coagulation, and division). The rate of ectopic pregnancies to total pregnancies for the less destructive methods ranged from 4% (spring clip) to 29% (bipolar, coagulation only). The ratio of reversal requests (3613) to the number of sterilizations performed (88,986) in 1979 is approximately 2% higher than that in 1976. Complication and mortality rates following laparoscopic sterilization and diagnosis have dropped from 2.7 complications/1000 sterilizations in 1976 to 1.8/1000 in 1979, from 5.4 complications/1000 diagnostic procedures to 2.6/1000 in 1979, and from 4 deaths/100,000 sterilizations in 1976 to 2/100,000 in 1979. No deaths from laparoscopic diagnosis were reported in either survey. An editorial note by Richard Soderstrom points out that without data on the time interval between sterilization and pregnancy, comparisons of pregnancy rates between the older and newer methods are not valid.
