Participants
During the study period, we screened 312 women, of which 199 did not meet our selection criteria and were excluded; 34 women had previous tubal surgery, 16 had previous EP, 17 had no fertility intention and in 132 women severity could not be confirmed during surgery. In total 113 women were followed up until July 2020 for the occurrence of live birth, 19 women were lost to follow-up; 8 in the salpingectomy group (4 at 2nd year, 3 at 3rd year, 1 at 4th year) and 11 in the neosalpingostomy group (2 at 1st year, 5 at 2nd year, 3 at 3rd year, 1 at 4th year) (Figure 1).
Among 113 women involved, 55 in the salpingectomy group and 58 in the neosalpingostomy group were included in the ITT analysis, eventually 78 women had a live birth (16 through natural conception and 62 through IVF). In the neosalpingostomy group, 15 women had additional salpingectomy for recurrent hydrosalpinges or for EP, among whom 8 had additional bilateral salpingectomy and were ruled out in the PP analysis.
