| Description | Aim: We present a group of patients, who underwent intervention procedures of the esophagus and biliary tract with the implantation of biodegradable (BDG) stents. Material and methods: BDG stent as stenoses treatment is a relatively young method. Its aim is to bridge stenotic section, then it will gradually degradate and separate. We have 15 patients between 2007 and 2009. Results: In group of patients with esophageal stents, one got 3 BDG stents gradually due to restenosis. In another case was the anastomotic stenosis dealt with metallic and plastic stents, which both dislocated, so BDG stent was used. In group of benign biliary tract stenoses, 5 patients were successfully treated with BDG stents. In patients with malignant biliary stenoses two patients had to underwent early biliary drainage because of stent failure. There are no long-term data in another two patients with recent stent implantation. There were no complications with stent placement. We observed one esofagotracheal fistula, which we believe is not due to BDG stent. Conclusion: Very successful results demonstrate the group of patients with benign biliary tract stenosis, 5 of 7 patients had no signs of cholestasis in follow up. In patients with malignant biliary tract stenosis seems BDG stent placement only a marginal option. Questionable results are in group of esophageal strictures, however more patients and longer follow up is needed. |
