[Notes on the use of the Angelchik-Cohen ring].

Results obtained by using Angelchik and Cohen's ring prosthesis in 10 patients with hernia due to sliding through the oesophageal hiatus of the diaphragm are reported. In 8 patients, the ring was perfectly tolerated and performed its antireflux and hernia containment functions. In the 2 other patients, however, the prosthesis rose to the mediastinum, causing hernia to recur in one case and leading to recurrence of symptomatology in the other.
