Minor Operation Boosts Risk of Premature Birth

Wednesday, 17 Jun 2015 09:01 AM


One of the commonest surgical procedures in gynecology greatly increases the risk that a woman will give birth prematurely in later pregnancies, a study said Tuesday.

Dilation and curettage -- D&C -- is routinely used by doctors after miscarriage or pregnancy termination, but researchers found it upped the risk of very premature births by nearly 70 percent.

The procedure entails dilating the cervix and removing any tissue remaining in the womb to prevent infection.

Generally considered safe and easy to perform, the 15-minute operation is being rivaled by less invasive methods but remains common.

In a review of 21 studies covering two million women, Dutch researchers found that D&C increased the risk of premature birth -- when a baby is born before 37 weeks -- in a subsequent pregnancy by 29 percent.

The risk of very premature birth -- before 32 weeks -- rose by 69 percent however. At this young age, a baby is at risk of medical complications, most require oxygen to help them breathe, and many need to be fed intravenously.

In the general population, the risk of pre-term delivery without a D&C is about six percent, the research found. The additional risk from the operation brings the figure to 7.6 percent.
The results "warrant caution in the use of D&C after miscarriage and induced abortion," said Pim Ankum of the Academic Medical Centre at the University of Amsterdam.

Dilation may impair anti-microbial defenses, causing genital tract infection, or weaken cervical tightening, both known factors for premature birth, suggested Ankum.

The research was unveiled in Lisbon at the annual conference of the European Society of Human Reproduction and Embryology (ESHRE), the organization said in a press release.
