OBJECTIVE. The purpose of this study was to evaluate the clinical features of patients with gastric conduit strictures after esophagectomy and to report our initial experience in the management of these strictures with fluoroscopically guided balloon dilation, temporary stent placement, or both. MATERIALS AND METHODS. From January 1996 to January 2012, 12 patients with gastric conduit stricture after esophagectomy underwent fluoroscopic balloon dilation, temporary stent placement, or both. Stent placement was indicated in patients who had gastrorespiratory fistulas or recurrent symptoms within 2 weeks of balloon dilation. Technical and clinical success, complications, and length of strictures were retrospectively evaluated. RESULTS. The mean length of strictures in all patients was 49 mm (range, 21-76 mm). The strictures were accompanied by gastrorespiratory fistulas in four patients. Seven patients with gastric conduit strictures without fistulas underwent 23 balloon dilations. Five patients underwent stent placement owing to gastrorespiratory fistula formation (n = 4) and frequent recurrent symptoms after balloon dilation (n = 1). During a mean follow-up period of 8 months (range, 2-28 months), clinical success was achieved in 11 patients (91.6%) after a single balloon dilation (n = 1), multiple balloon dilations (n = 5), or stent placement (n = 5). Complications occurred in 3 of 10 patients (30%) after balloon dilation and in one of five patients (20%) after stent placement. CONCLUSION. Gastric conduit strictures are characterized by their substantial length and tend to be accompanied by gastrorespiratory fistulas. Despite relatively high complication and recurrence rates, this study may offer a viable treatment of gastric conduit strictures by using fluoroscopically guided balloon dilation and stent placement.
