Small Bowel Perforation Secondary to Esophageal Stent Migration: A Comparative Review of Six Cases

Esophageal stent placement is used to treat benign strictures, esophageal perforations, fistulas and for palliative therapy of esophageal cancer. Although it is a safe and effective method, complications are increasing the morbidity and mortality rate. Small bowel perforation as a result of esophageal stent migration is a remarkably rare occurrence. We report one case from our clinical experience and undertake a review of the previously reported cases retrieved from the PubMed. A total of six cases were found accessible. Abdominal pain was the common clinical presentation. The mean time from stent placement to perforation was 3.4 months (range, two weeks to 12 months). The jejunum was the frequently perforated portion of the small bowel. Surgical intervention was the mainstay of treatment. This comparative review illustrates that clinicians should remain vigilant for small bowel perforation in patients with esophageal stent placement. Further studies are required to delineate the magnitude and scope of this association.
