[Pregnancy after treatment of obesity using jejuno-ileal anastomosis]

The authors report on 5 cases of pregnancy in women who had previously received a jejunoileal bypass for obesity. In two patients, menstruation had normalized after the operation. None of the patients changed her eating habits during the time of pregnancy and both their antenatal courses and births revealed no complications. All the babies were healthy and well developed. Conception occurred 6 to 18 months after the operation, which proved to be sufficient to avoid a fatal fatty metamorphosis of the liver. It can therefore be said that a weight reduction due to the jejunoileal bypass represents no contraindication for pregnancy; sometimes extremely obese women could even become pregnant after the operation. With a careful supervision of the electrolyte balance and the albumen and iron concentration, a jejunoileal bypass means no increased risk for mother and child, neither during delivery nor during the ante- or postnatal period.
