  • Title: The Angelchik antireflux device: a 5-year experience.
    Author: Timoney AG, Kelly JM, Welfare MR.
    Journal: Ann R Coll Surg Engl; 1990 May; 72(3):185-7. PubMed ID: 2357036.
    Abstract:
    A total of 44 patients had an Angelchik antireflux prosthesis inserted over a 5-year period. Of these, 41 were available for review and were assessed by interview using a modified Visick grading. Of the 23 patients followed up for a minimum of 3 years 74% had an excellent or satisfactory outcome; 92% of patients with symptoms of reflux obtained relief, but less than 50% of those patients presenting with dysphagia had a satisfactory outcome. The incidence of mild postoperative dysphagia increased the longer the period of follow-up. The main cause of a Visick 3 or 4 result was prosthesis migration. We have modified our technique of insertion to reduce these complications, and in a more recent series have achieved a Visick Grade 1 or 2 in up to 92% of patients. We conclude that dysphagia is a relative contraindication to the insertion of the Angelchik prosthesis. Our recent results encourage the use of the prosthesis provided steps are taken to reduce the incidence of migration and pericapsular fibrous tissue formation.
