The Angelchik antireflux prosthesis.
A silicone collar containing circumferential tape was tied around the cardio-esophageal junction in eight patients with symptomatic, refractory reflux, who were not good candidates for a standard antireflux procedure. A fine polypropylene tie or clip secured the knot. In two patients with large hiatal defects, the crura were approximated loosely. Mean operating time, including one cholecystectomy and one ventral hernia repair, was 51 minutes. Patients who underwent this simple operation had a combination of hypertension, heart disease, obesity and old age, and two had undergone horizontal gastroplasty previously for morbid obesity. The reflux was associated with hiatal hernia in seven of the eight patients. Preoperative studies included barium swallow roentgenography in all eight patients, and endoscopy, manometry and Bernstein test in six. All the studies were repeated postoperatively. Follow-up ranged from 17 to 48 months (mean 37.8 +/- 10.6 months). Postoperatively, there was a significant (p less than 0.01) improvement in symptoms, endoscopic findings and lower esophageal sphincter pressures. No prosthesis has migrated yet.
