[Pregnancy after surgical therapy of obesity. Bibliographic review and our experience with biliopancreatic diversion].

BACKGROUND
An increasing number of women in childbearing age are submitted to surgical treatment of obesity; for this reason pregnancy represents a frequent event in operated patients.


METHODS
In this study pregnancy in patients with morbid obesity submitted to jejunoileal bypass (JIB) and gastric bypass (GB) are reviewed from the literature and the analysis of our experience with biliopancreatic diversion (BPD) is reported.


RESULTS
In 113 pregnancies after JIB reviewed from the literature, the results seem to be debated either about the course of pregnancy or about maternal and neonatal status. The data of literature concerning the pregnancies following GB are less debated but rather slight. One hundred and fifty-two pregnancies after BPD have a complete documentation concerning maternal conditions, modality of outcome and neonatal situation.


CONCLUSIONS
Pregnancy occurred in the obese women represents an increased maternal-fetal risk. The excess weight loss, the weight maintenance and the reduced weight changes during pregnancy are an advantage in the operate women who, in any case, need accurate controls of the nutritional status during the whole gestational period. Keeping these cautions pregnancy following surgical treatment of obesity represents an event not only possible but even with less problems than in pregnancy in obese women.
