Objective:

We set to evaluate the effects of maternal obesity on surgical morbidity outcomes in cases of placenta accreta spectrum (PAS).

Study Design:

This was a multicenter retrospective cohort study of histopathologically confirmed PAS cases 1/1/2013 - 6/30/2022 at five New York academic institutions. Maternal obstetrical and demographic variables were collected. The cohort was divided into two groups, obese (body mass index (BMI) ≥30 kg/m2) and non-obese (BMI < 30 kg/m2). The primary outcome was a composite of PAS related surgical outcomes, including intensive care unit (ICU) admission, vasopressors use, intubation, blood loss, organ injury, and transfusion. Univariable analysis compared variables using chi square test for categorical and Mann Whitney U/student t for continuous variables. A logistic regression analysis was then performed adjusting for statistically significant variables between the two groups.

Results:

Of the 401, 377 cases had documented maternal pre-pregnancy BMI. There were 159 obese and 218 non-obese patients. Obese patients were more likely to have a vertical skin incision, less likely to have undergone artificial reproductive technology, present later in the pregnancy for prenatal care and more likely to have been diagnosed with PAS antenatally (55.6% vs. 36.8%, p< 0.001, 20.2% vs. 5.1%, p< 0.001, 12 (9, 16) vs. 10 (8, 13) p=0.004, 98.7% vs.91.2%, p=0.002). After adjusting for significant variables, aside from an increased risk of intubation in the obese group (aOR=1.82 with 95% CI 1.09-3.03), surgical morbidity composite did not differ between obese and non-obese patients (aOR 0.39, 95% CI 0.11-1.37).

Conclusion:

Obese and non-obese patients had similar odds of surgical morbidity for most outcomes. Our findings suggest the impact of obesity on PAS surgical morbidity may be more nuanced and that the interplay between obesity and PAS outcomes deserves further investigation.
