Pregnancy rates after reconstructive surgery on the fallopian tubes

Between 1965 and 1972, 66 patients at the Johns Hopkins Hospital had tuboplasties: 2-1 salpingolyscs, 18 fímbrioplasties, 6 anastomoses, 8 cornual implantations, and 10 multiple procedures. Thirty-nine percent of these patients became pregnant during the follow-up periods, with an average treatment to pregnancy interval of 35 months. This pregnancy rate, however, depended on the length of the followup—the shorter the duration of followup, the lower the pregnancy rate. In order to circumvent this problem, expectancies of pregnancy, when followed up for an indefinite tinte, were calculated by computer. By this algorithm, it was found that 50% of patients could expect pregnancy following tuboplasties of all kinds: G6% after tubolysis, 40% after fimbrioplasty, 50% after anastomosis, 38% after cornual implantation, and 21% after multiple procedures.
