title: Clinical experience with Montgomery salivary bypass stents in the esophagus.
abstract: Thirty-seven patients with locally advanced malignancy (18, esophageal obstruction; 19, esophageal fistula formation) underwent attempted placement of a Montgomery salivary stent in the esophagus. This was unsuccessful in 3; in 2, because of inability to dilate, and, in 1, because of perforation. After dilation of the esophagus, there was no detectable underlying stricture in 11 patients; none of these patients experienced stent migration. Overall, there was 100% success in obliterating the fistulous tract, an 8.1% incidence of retrograde migration, no incidence of prograde migration, and no incidence of stent obstruction after discharge. Of the 34 patients with successfully placed stents, 27 were discharged from hospital, and were able to eat and drink without the need for intravenous supplementation or gastrostomy tube feedings. The survival in patients presenting with obstruction ranged from 1 to 13 months (mean, 8.0 months); the survival in patients presenting with a fistula ranged from 2 to 7 months (mean, 5.3 months).
