Purpose. Weight loss after bariatric surgery occurs by preferential loss of visceral and central body fat. We hypothesized that 2 nd trimester sonographic completion rates would be higher among women with prior gastric bypass compared with women of similar body mass index without a prior gastric bypass. Methods. Women with gastric bypass undergoing 2 nd trimester sonographic examination were matched 1:1 with controls for body mass index and prior cesarean section. The primary outcome was completion of the fetal anatomic evaluation according to American Institute of Ultrasound in Medicine guidelines. Results. Initial sonogram completion rates for cases, 28/40 (70%), and controls (30/40, 75%) were similar ( p = 0.62). Completion rates for women returning for follow‐up were 100% in both groups. Overall completing rates were identical for cases (37/40, 92.5%) and controls (37/40, 92.5%). Conclusion. Previous gastric bypass surgery does not affect 2 nd trimester sonographic completion rates. © 2010 Wiley Periodicals, Inc. J Clin Ultrasound, 2010
