[The Angelchik prosthesis. A computed tomography study]. / La protesi di Angelchik. Studio mediante Tomografia Computerizzata.

The Angelchik prosthesis is used in the surgical treatment of gastroesophageal reflux. Operated patients are primarily examined with imaging techniques, but manometric and acidometric techniques are also used. Although the conventional esophagogram still maintains its diagnostic significance, computed tomography (CT) has become the first-choice imaging modality. CT allows the correct evaluation of both the state of the prosthesis and its relationship to the esophagus and the gastric fundus. The possible postoperative complications following an incorrect placement of the prosthesis can be accurately diagnosed too. The authors report their experience in the study of 5 patients examined with both conventional radiology and CT.
