Elective suture of uterine cervix in triplets

The incidence of triplet pregnancies has increased several times due to the widespread use of ovulation induction agents. Premature delivery is the main complication of triplet gestations. In twin conceptions it was shown definitely that elective cervical suture does not prolong these pregnancies. However, in higher order multifetal gestations the uterus is extremely overdistended and the application of cerclage is equivocal. This work intended to assess the value of elective cervical sutures in prolonging triplet pregnancies. Twelve of 35 women with triplet conceptions hospitalized at our high-risk pregnancy unit underwent an elective cerclage at 12 to 14 weeks and 23 women served as control subjects. None of them had any history or physical findings of cervical incompetence prior to the procedure. The gestational age (weeks) at delivery was 33.0 +/- 5.1 and 34.7 +/- 2.8 (mean +/- SD) for the sutured and noncerclage groups, respectively. The birthweight (grams) of the neonates was 1833.0 +/- 524.5 and 1884 +/- 455.5 (mean +/- SD) for the cerclage and nonsutured women, respectively. It seems that triplet gestations as such do not benefit from an elective cervical suture.
