Falciform ligament: a cause of extrinsic antral obstruction in the neonatal period.

We are describing two cases of neonatal antral obstruction due to the presence of an abnormal falciform ligament. Abdominal palpation revealed a cord in the right hypochondrium. In one case, a barium swallow revealed a very short extrinsic compression of the antrum. Division of the abnormally wide fibrous falciform ligament cured the babies.
