Study examines self-expanding plastic stents in the treatment of benign esophageal conditions

Date:1/25/2008

curred in more than 60 percent of all patients and of all stents placed, said the studys lead author Todd Baron, MD, FASGE, Mayo Clinic, Rochester. Stent migration rates were not influenced by dilation at the time of stent placement or stent size. Although stent placement typically resolved the patients symptoms initially, long-term resolution was infrequent in our study group. Only six percent of all procedures provided long-term resolution of symptoms after stents were removed.

Patients and Methods

This study was a retrospective review of cases of benign esophageal lesions in which a self-expanding nonmetallic Polyflex stent was placed at the Mayo Clinic, Rochester, from 2002 to 2006.

Thirty patients underwent at least one attempted SEPS placement. Nineteen patients were male and 11 were female, with an average age of 52.1 years. Twenty-two stents were placed in eight patients for benign strictures. Twenty-five stents were placed in 11 patients for anastomotic stricture after esophageal surgery. Twenty-two stents were placed in nine patients for esophageal fistulae or anastomotic leak. Fifteen stents were placed in five patients, and one stent placement was unsuccessful in one patient for radiation-induced strictures. A total of 83 stent placements were performed over the five-year period.

Overall, complications were minor and did not interfere with subsequent treatment. The most common initial complaints included chest pain, neck discomfort, and dysphagia (in 23 procedures) and nausea and vomiting (in eight procedures) and were managed with analgesic and antiemetic medications. Symptoms resolved within three days in most cases.

Results

Stents remained in place for an average of 53 days. Patients had symptomatic improvement initially in 77 of 83 stents placed (92.8 percent), three of 83 stents placed resulted in no symptom improvement, and three of 83 stents placed are awaiting follow up informat
