Comparison of Pregnancy and Neonatal Outcomes Before and After Laparoscopic Sleeve Gastrectomy in Women Diagnosed With Obesity

Abstract

Objectives This study aimed to compare pregnancy and neonatal outcomes before and after laparoscopic sleeve gastrectomy in women diagnosed with obesity. Methods Female patients who underwent laparoscopic sleeve gastrectomy with the diagnosis of obesity at Ondokuz May & imath;s University Faculty of Medicine between 11.01.2015 and 17.03.2025 were included in the study. The patients were divided into two groups as those who became pregnant after the operation (n = 59) and those who did not (n = 435). Pregnancy and delivery outcomes of the women who became pregnant before and after the operation were compared. Results Pregnancy rate after LSG was 11.9% in our sample. Age mean for pregnancy patients after LSG (31.22 +/- 4.45) were significantly lower (p < 0.05), whereas BMI mean differences between postop pregnant and non-pregnant group were insignificant (p > 0.05). DM, HT, PCOS, anxiety, asthma and hypothyroid distribution differences were also insignificant between postop pregnancy groups (p > 0.05). Pregnancy month after operation was ranged from 6 to 60 months with 25.22 +/- 13.84 months mean. DM frequency was 6.8%, HT, PCOS and anxiety frequencies were 5.1%. 45.8% of patients had operation history. Birth weight and mother age were significantly higher in postop pregnant after LSG patients (p < 0.05). Pregnancy BMI was significantly lower after LSG (p < 0.05). Congenital anomaly was more common in postop pregnant after LSG patients (p < 0.05). All other pregnancy and delivery outcome differences between patient groups were statistically insignificant (p > 0.05). Conclusion Pregnancy rates in pregnant women after LSG were over 10%. Birth weight, BMI during pregnancy and congenital anomaly differed before and after LSG. Further studies are needed on the relationship between congenital anomaly and LSG.
