Abstract
A prospective study has been made of the use of the Angelchik prosthesis in the treatment of hiatus hernia and gastro-oesophageal reflux. Forty-one patients under the care of one surgeon were studied over a 3-year period. The operation is simple and safe to perform. Twelve patients suffered transient dysphagia which spontaneously resolved within 3 months. Satisfactory results were obtained thereafter in 80·9 per cent. Seven of the prostheses have been removed (17·1 per cent), all within 18 months of performing the operation. Dysphagia and recurrent symptoms were the main reasons for removal and in two of these stricturing was present pre-operatively. We feel the presence of an established stricture is a contraindication to the use of the device. We have, however, been impressed by its use as a second procedure when previous surgery has failed and when revisional surgery for recurrent hiatus hernia is difficult due to dense adhesion formation. While it is still early to assess the legacy that the use of this prosthesis might incur, we would recommend conservatism if not abandonment of its use until longer-term evaluation is available.
