[Maternal and neonatal complications in a pregnant woman with biliopancreatic diversion].

Biliopancreatic diversion (BPD) is a bariatric technique which can lead to the development of nutritional complications such as protein-calorie malnutrition and deficiencies in fat-soluble vitamins. Many women in childbearing age undergone DBP, pregnancy frequently occurs afterwards. Vitamin A is essential for the differentiation and growth of cell during embryonic development. Although BPD has shown beneficial effects in some obstetric and reproductive complications as infertility and macrosomia, several reports suggest a link between maternal malnutrition and fetal or neonatal complications. We present the case of a pregnant woman with a severe malnutrition associated with vitamin A deficiency as a result of a BPD. The patient delivered a premature infant, with low birth weight and significant eye and kidney malformations. We review and discuss the probable relationship between adverse neonatal outcome, malnutrition and vitamin A deficiency during pregnancy.
