Sonographic appearance of a migrated Angelchik anti-reflux prosthesis in the pelvis.

Surgical implantation of Angelchik prosthesis around the distal esophagus was a popular treatment for gastroesophageal reflux in the 1980s. However, because of frequent complications, this surgical technique was abandoned. We report a case of a migrated Angelchik prosthesis in a 56-year-old woman in whom the prosthesis was found in the pelvic cavity 20 years after the initial surgery. The plain radiographic and ultrasound findings are described.
