Conclusion  Our early results indicate that conversion of failed VBG to BPD is highly effective with acceptable morbidity. Our data show that the effect on weight is strongly dependent on the indication for the conversion. Conversion to BPD, in such a group of patients, is a wise alternative, since it may reduce operative risks.
