A Cochrane review [Abstract] 1 included 11 studies with a total of 1386 subjects. Laparoscopic salpingectomy increased clinical pregnancy rate (CPR) (RR 2.02, 95% CI 1.44 to 2.82; 4 RCTs; n = 455; I² = 42.5%). This suggests that in women with a CPR of approximately 19% without tubal surgery, the rate with salpingectomy lies between 27% and 52%. Tubal occlusion increased CPR compared to no tubal surgery (RR 3.21, 95% CI 1.72 to 5.99; 2 RCTs; n = 209). Laparoscopic occlusion of the fallopian tube versus no intervention increased CPR (RR 3.21, 95% CI 1.72 to 5.99; 2 RCTs; n = 209; I² = 0%). This suggests that with a CPR of approximately 12% without tubal surgery, the rate with tubal occlusion lies between 21% and 74%. Comparison of tubal occlusion to salpingectomy did not show a significant advantage of either surgical procedure in terms of CPR or live birth rate.
