Objective:
The use of intraoperative ultrasound guidance for second-trimester elective dilation and curettage reduces the incidence of uterine perforation. However, the role of intraoperative ultrasound guidance during curettage following second-trimester delivery has not been evaluated. We aim to evaluate the effect of intraoperative ultrasound guidance during curettage following second-trimester delivery.
Methods:
We conducted a retrospective cohort study that included patients who had a second-trimester delivery at up to 236/7 weeks gestation and underwent uterine curettage after the fetus was delivered.
Results:
Overall, 273 patients were included. Of them, 194 (71%) underwent curettage without intraoperative ultrasound guidance, while 79 (29%) underwent the procedure utilizing intraoperative ultrasound guidance. The overall rate of a composite adverse outcome was higher among those undergoing curettage under intraoperative ultrasound guidance compared with no ultrasound guidance (31 [39.2%] vs. 40 [20.6%]; OR 2.4; 95% CI 1.4-4.4, P = 0.002). Placental morbidity (10 [12.6%] vs. 11 [5.6%]; OR 1.9; 95% CI 1.01-5.9, P = 0.04) and infectious complications (6 [7.5%] vs. 5 [2.5%]; OR 3.1; 95% CI 1.01-10.4, P = 0.05) were more frequent among those undergoing curettage with intraoperative ultrasound guidance. In a multivariate logistic regression analysis, intraoperative ultrasound guidance was the only independent factor positively associated with the occurrence of an adverse outcome (adjusted OR 1.93; 95% CI 1.1-3.4, P = 0.02). Procedure time was longer when ultrasound guidance was used (9:52 vs. 6:58 min:s; P < 0.001).
Conclusion:
Intraoperative ultrasound guidance during curettage after second-trimester delivery is associated with a higher complication rate than no guidance.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
