OBJECTIVE To analyze the causes of failure of esophageal stent implantation and explore technical improvement of re-implantation of esophageal stent (RIES). METHODS According to the conditions of the failed stent implantation, 32 patients who required RIES underwent placement of more appropriate esophageal stents with an improved implantation technique. The patients were followed up for 6 months after the operation to evaluate the effects of RIES. RESULTS The success rate of the operation was 96.9% in these cases, and the esophageal conditions including stricture and fistula were effectively relieved. During the 6-month follow-up, stent migration occurred in 4 cases (12.5%), and esophageal fistula in the upper edge of the re-implanted stent occurred in 2 cases. No stent loss, bleeding, or stricture was found in these cases. CONCLUSION The improved technique is effective for stent re-implantation after failed esophageal stent implantation with reduced complications associated with esophageal stenting.
