title: Application of self-expanding metallic stents to malignant stricture following mechanically stapled esophagojejunostomy: report of two cases.
abstract: Several types of self-expanding metallic stents (SEMS) were placed in two patients suffering from severe malignant stricture at the site of a mechanically stapled esophagojejunostomy used for the treatment of recurrent gastric cancer. Following modified Gianturco stent placement with limited success in one of the patients, an additional Ultraflex stent (Boston Scientific Co., Boston, USA) failed to expand satisfactorily at the outlet of the second stent. In the other patient, since the proximal end of an additional covered Ultraflex stent (Boston Scientific Co.) inserted through the first one failed to expand satisfactorily at the level of severe stenosis because of the extreme rigidity caused by the mechanical staples, a spiral Z-stent was inserted to dilate it. The cases reported here raise some problems associated with the treatment of severely malignant stricture accompanied by extreme rigidity following mechanically stapled esophagojejunostomy with SEMS.
