- W1738101715 abstract "SUMMARYAim: The evaluation of efficacy and safety of autoexpandablemetal covered stend endoscopic placement in patients withmalignant esophageal obstructions or stenoses.Patients and Method: We retrospectively analysed a totalof 61 patients with malignant esophageal obstruction dueto esophageal (n=25), pancreatic (n=1), breast (n=4) andlung cancer (n=29), primary esophageal melanoma (n=1)and recurrence of gastric adenocarcinoma after gastrectomy(n=1). The site of obstruction was in the upper (n=1),middle (n=34) and lower esophagus (n=23). In 9 casesgastro-esophageal junction was included. In all patients thetumour was considered nonresectable. Between 5/1997-6/2001, 61 Ultraflex covered stents and 4 Flamingo type wereintroduced endoscopically. 36 patients required dilation.Results: Stents were placed successfully in all cases. After48h all patients were able to tolerate solid or semi-soliddiet. Thirty-seven died 32+6 weeks later, none due to a causerelated to the stent. During the follow-up period, 5 patientsdeveloped dysphagia due to food impaction. One stent 3weeks after placement, in a case involving gastro-esophagealjunction, migrated to the stomach and a new one was placed.Eight patients presented recurrent dysphagia. Four of thesewith tumour overgrowth at the distal end of the stenosiswere treated with introspective application of Diamed laser (contact fiber) in a total of 13+6 sessions per patient (6782joules, range 4380-10584 j per session). In the remaining 4cases, a second stent was placed. No other side effects werenoted.Conclusion: Placement of self-expanding metal stents is asafe and effective treatment modality for malignantesophageal obstruction. In case of expansion of the mass,laser therapy or placement of a second stent could be used.Key words: Esophageal malignant obstruction, metal stent,Diomed laser, palliative treatment" @default.
