Complications after use of the Angelchik antireflux prosthesis.

We report two cases of severe complications after insertion of an Angelchik antireflux prosthesis. In one case, the prosthesis migrated into the pelvis. In the other, severe dysphagia resulted from its insertion. In both instances, surgical removal was required. The high incidence of complications following the use of this prosthesis would suggest that other safer antireflux operations should be the preferred form of therapy.
