The Angelchik prosthesis for gastro-oesophageal reflux: symptomatic and objective assessment.
Twenty-three patients with intractable gastro-oesophageal reflux were treated by insertion of the Angelchik antireflux prosthesis. Good symptomatic relief was achieved in over 80% of patients reviewed up to 28 months after operation and there was marked resolution of oesophagitis as seen on endoscopy. Oesophageal manometry and pH studies performed preoperatively and at 3 and 12 months after operation, showed a significant increase in lower oesophageal sphincter pressure with decreased acid reflux. Some technical problems were encountered, but the prosthesis is potentially a simple and effective means of controlling gastro-oesophageal reflux.
