Abstract

BACKGROUND: Dilation and Curettage (D&C) may be performed with or without transabdominal ultrasound guidance. We aimed to evaluate the association between the use of ultrasound guidance during D&C for first-trimester missed abortion (MA) and D&C related complication rates.

METHODS: A retrospective cohort study including women in the age of 20-45 years, who underwent D&C for first-trimester MA in a hospital-based setting between 2013-2019. The study population was divided into two groups - the study group which included women who underwent D&C with ultrasound guidance (US group) and the control group, which included women who underwent D&C without ultrasound guidance (N-US group). Gynecologic, obstetric and operative related data were collected from electronic medical records.

RESULTS: Three-hundred and seventy-eight women were included in the study, 86 women in the US group and 292 women in N-US group. Baseline maternal characteristics and procedure-related characteristics did not differ between the groups. No significant difference between the US group and N-US group was shown when comparing D&C related complications - retained products of conception rate (2.3% vs. 5.5%, respectively; p=0.385), uterine perforation rate (1.2% vs. 0.3%, respectively; p=0.404), and the total complication rate (8.1% vs. 12.3%, respectively; p=0.338). In a multivariate analysis, the use of ultrasound guidance during D&C was not found to be associated with lower complication rate (adjusted Odds Ratio (aOR) 95% confidence interval (CI) 1.468 (0.578-3.729), p=0.419).

CONCLUSIONS: Performance of D&C under ultrasound guidance for first-trimester MA, in a hospital-based setting, was not associated with lower complication rate, suggesting that the common practice of performing D&C without the use of ultrasound is an acceptable approach.
