Pregnancy and delivery after lower body contouring surgery is safe for the mother and child

Perinatal outcomes following abdominoplasty: a retrospective study and review of current literature

BACKGROUND

Abdominoplasty surgery is a common body contouring surgery to remove excess fat and skin and restore weakened or separated abdominal muscles caused by aging, pregnancy, or weight fluctuations. There is limited literature regarding patient and pregnancy outcomes after abdominoplasty.

OBJECTIVE

This study aimed to determine whether there was a correlation between adverse pregnancy outcomes and history of abdominoplasty.

STUDY DESIGN

Our study used a large federated deidentified national health research network with data sourced from 68 healthcare organizations within the United States (TriNetX; data accessed on August 19, 2022). All patients with a record of pregnancy were identified using the International Classification of Diseases, Ninth Revision and Tenth Revision, codes and were grouped into those with a history of abdominoplasty and those without. This study evaluated the perinatal outcomes of fetal growth restriction, abnormal umbilical artery Dopplers, gestational hypertension, preeclampsia, preterm delivery, preterm premature rupture of membranes, gestational diabetes mellitus, macrosomia, stillbirth, abnormal placentation, and wound disruption or infection occurring during a patient's pregnancy after abdominoplasty. Propensity matching was performed to account for potential confounders. An alpha level of <.05 was considered statistically significant.

RESULTS

Of the 44,737 patients meeting our criteria, 304 had a history of abdominoplasty, whereas 44,433 did not (control). Our study found that patients with a history of abdominoplasty had significantly higher gravidity, were largely located in the Southern and Midwest region, and had higher counts of vaginal deliveries and cesarean deliveries than the control cohort (Table 1). After propensity score matching, our study found a lower risk of preeclampsia and preterm premature rupture of membranes in patients with abdominoplasty (odds ratio, 0.46; 95% confidence interval, 0.32-0.67; P<.0001) (Table 2). Furthermore, abdominoplasty was associated with an increased risk of preterm delivery (odds ratio, 2.15; 95% confidence interval, 1.48-3.13; P=.0002) (Table 2). Lastly, this study did not find significant differences in the other perinatal outcomes (Table 2).

CONCLUSION

Our data suggest that abdominoplasty may be associated with a relative increase in the rates of preterm delivery and cesarean delivery and that other perinatal outcomes are not increased. This provides evidence that future desire for pregnancy need not be a relative contraindication to abdominoplasty.

Pregnancy Complications in Women with Weight Loss Surgery Compared to a Non-Surgical Population of Women with Obesity

BACKGROUND

The objective of this study was to assess the effect of WLS on pregnancy and delivery complications in women who had WLS compared to women with obesity who did not undergo WLS.

METHODS

We used the National Inpatient Sample data from 2012 to 2017, with a study population of women between the ages of 20 and 44 who had a maternal admission code in the NIS data (n = 663,795). Weighted logistic regression models were fitted and the models were stratified by race. Covariates included age, race, primary payer, previous cesarean delivery, physical health comorbidities, and depression.

RESULTS

There were decreased odds of gestational diabetes in women of all races (aOR_all = 0.47, 95% CI_all = 0.44-0.49). There were decreased odds for gestational hypertension in women of all races (aOR_all = 0.55, 95% CI_all = 0.51-0.59). Compared to women who did not have WLS, there were lower odds of cesarean delivery among women with a history of WLS (aOR_all = 0.62, 95% CI_all = 0.60-0.65), which was true for White women, Black women, and Latinas with a history of WLS (aOR_White = 0.57, 95% CI_White = 0.53-0.60; aOR_Black = 0.67, 95% CI_Black = 0.61-0.74; aOR_Latina = 0.71, 95% CI_Latina = 0.64-0.78).

CONCLUSIONS

Overall, women with history of WLS had lower odds of most of the pregnancy outcomes (gestational diabetes, gestational hypertension, pre-eclampsia/eclampsia, and cesarean delivery) with results mediated by race.
