Abstract
|
|
|
Since the insertion of self expandable metalic stent (SEMS) has become popular mothod for hollow organ stenosis, many attempts for further apply the stent to airway stenosis as an simple procedure has been made, but intrabronchial migration of
stent or
occurrence of inflammatory granuloma around stent develop occasionally and somtimes it worsen bronchial stenosis further more. This report describes 2 case of surgically treated bronchial restenosis in whom intrabronchial stent were applied for
release
of bronchial stenosis Our surgical option was pneumonectomy and bronchoplasty with sleeve right middle and upper lobectomy respectively. During the operation we found the SEMS were tightly impacted in restenotic bronchial lumen with overgrowth of
granulation tissues. The bronchial obstructions occupied more than 90% of lumens in both cases, and needed much complicated procedure to be relieved. Therefore, even though the insertion of SEMS remains as a prcedure determined by the physician's
preference, it has to be considered prudently that the use of SEMS can cause severe restenosis and the surgeon has more difficulties in performing segmental resection of restenotic bronchus in patient with SEMS previously inserted. Throughout
these
experiences we can conclude that the insertion of SEMS must be performed only in very selected cases of bronchial stenosis.
