Laparoscopic Roux-en-Y gastric bypass as a treatment of severe obesity has increased dramatically in the past decade, and most of the patients have been women [1,2]. The health risks experienced by obese women during pregnancy can be reduced by the weight loss induced by bariatric surgery [3–5], but these patients are at risk of bariatric surgical complications during their pregnancies. Women who have undergone Roux-en-Y gastric bypass for morbid obesity are at risk of internal hernias, intussusception, and small bowel obstruction during pregnancy, which can lead to maternal and/or fetal death [6].
