The objective of this study was to investigate pregnancy outcome of patients following different types of bariatric surgery.
A population-based study includes all pregnancies of patients with bariatric surgeries delivered during 1988–2008. Pregnancy outcome was compared between the different types of surgeries.
This retrospective study included 449 deliveries: 394 deliveries following pure restrictive operations—laparoscopic gastric banding (LAGB; n = 202), silastic ring vertical gastroplasty (SRVG; n = 136), and vertical-banded gastroplasty (VBG; n = 56)—and 55 deliveries following restrictive and malabsorptive Roux-en-Y gastric bypass (RGB). While no significant differences were noted between the groups regarding body mass index (BMI) before the bariatric operations or prepregnancy BMI, patients following LAGB had significantly higher BMI before delivery (36.8 ± 5.9 kg compared to the SRVG 33.4 ± 6.0, VBG 34.2 ± 5.4, and RGB 34.9 ± 6.8 groups; p < 0.001). Following LAGB, patients had higher weight gain during pregnancy (13.1 ± 9.6 kg) compared to the SRVG (8.8 ± 7.4), VBG (8.5 ± 8.0), and RGB (11.6 ± 9.6; p < 0.001) groups. The interval between operation and pregnancy was shorter in the LAGB group (22.8 months) compared to the SRVG (41.0) and the VBG (42.1) groups and was significantly higher in the RGB group (57.4; p < 0.001). Birth weight was significantly higher among newborns of patients following RBG (3,332.8 ± 475.5 g) compared to the restrictive procedures (3,104.3 ± 578.7 in the LAGB, 3,086.7 ± 533.1 in the SRVG, and 3,199.2 ± 427.2 in the VBG groups). No significant differences in low birth weight (<2,500 g) or macrosomia (>4,000 g), or low Apgar scores or perinatal mortality were noted between the groups.
There is no difference in the affect on pregnancy outcome among the different forms of bariatric surgeries; all procedures have basically comparable perinatal outcome.
