[Treatment of esophageal reflux by insertion of Angelchik prosthesis: analysis of the follow-up in 26 patients].

The authors report a retrospective analysis of the immediate and long-term results of treatment of gastroesophageal reflux refractory to medical therapy using the insertion of Angelchik's prosthesis in a group of 26 patients operated at the Institute of Emergency Surgery of Turin University from January 1980 to December 1993. All patients underwent pre- and postoperative endoscopy and were then controlled using esophagogastric X-ray, esophagogastroscopy, esophageal manometry and pH-metry in the event of disorders of esophageal motility. Operative mortality was nil and no major surgical complications were reported. Postoperative endoscopy showed the resolution of esophagitis in 23 patients (88.4%); symptoms of slight esophagitis persisted in 2 cases, and moderate esophagitis in another. Eighteen patients were monitored over time with a minimum follow-up of more than 2 years: persistent dysphagia appeared in 3 cases (16.6%), and in one patient this led to the need for endoscopic dilatations. Two patients (11.1%) presented "gas bloat syndrome" which gradually improved. It was never necessary to remove the device. No cases were observed of erosion, migration or destruction of the prosthesis. Follow-up exceeded 10 years in 7 patients, at present asymptomatic. Angelchik's prosthesis proved to be efficacious, rapid and simple to insert, and characterised by a lower morbidity rate and shorter postoperative course. The incidence of postoperative dysphagia makes only it is use indicated only in patients with a high operative risk, obese subjects and in case of recidivation of reflux after fundoplication.
