Minor differences with electric and manual aspiration of molar pregnancy

“In our sample, formed exclusively by patients with molar pregnancy, the rate of complete uterine emptying did not reach 90% with either technique,” the authors wrote. “This may reflect not only the greater amount of molar trophoblastic tissue, compared with an abortion, but also the invasiveness of molar trophoblastic cells into the maternal decidua.”

There were nine cases of uterine perforation in the electric vacuum aspiration group (0.7%), and none in the manual group, although the difference was not statistically significant.

“Although differences in rates of uterine perforation as well as prolonged length of stay were not statistically different between the groups,” the authors wrote, “both of these were rare events, and we lacked sufficient power to detect differences in rare outcomes.”

No conflicts of interest were declared.
