Palliative treatment of inoperable malignant esophageal strictures with conically shaped covered self-expanding stents.
OBJECTIVE
To investigate the effectiveness of conically shaped covered self-expanding (Flamingo) stents in palliative treatment of malignant esophagogastric strictures in terms of patency, improved dysphagia score and survival.


METHODS
Flamingo stents were placed under fluoroscopic guidance between August 1998 and December 1999 for palliation of malignant dysphagia in 33 cases. There were 21 males and 12 females aged 40--80 years (average 64.2 years).


RESULTS
Stent placement was successful in all patients, with good symptomatic control and no procedure-related complications. Spontaneous esophago-respiratory fistula and perforation accompanying malignant esophageal stricture in a total of 4 cases (12.2%) were successfully closed. In 1 case, tumor ingrowth was detected from the distal uncovered segment of the stent. In 2 cases with esophago-respiratory fistula, gastrointestinal bleeding occurred. The cause of hemorrhage could not be found by angiography. The mean survival time in 17 patients, later deceased, was 129 days (range 9--360), and the mean observation time in 16 patients still alive is 180 days (range 18--365).


CONCLUSIONS
Flamingo stents provide an effective and safe choice of palliative therapy in inoperable malignant esophagogastric strictures.
