title: Treatment of pharyngoesophageal stenosis by polyvinyl prosthesis.
abstract: Many authors have objected to the use of esophageal stents in the palliative management of lesions obstructing the cervical esophagus, especially when the prosthesis must lie within 2 cm of the cricopharyngeus muscle (CPM). Ten patients with stenosis of the cervical esophagus by lesions within 2 cm of or involving the CPM were considered for prosthesis placement. The prosthesis was successfully placed in eight patients, five of whom had a tracheoesophageal fistula (TEF). A prosthesis could not be placed in two patients, and two patients complained of a minimal but tolerable foreign body sensation. Six prostheses were custom-made. The necessity to place a prosthesis within 2 cm of or even immediately proximal to the CPM should not be considered an absolute contraindication to esophageal prosthesis placement in selected patients. Foreign body sensation may be absent or minimal, and stent migration is common.
