METHODS:Different intervention procedures were used to treat benign stricture of GIT in 180 patients including pneumatic dilation (group A,n=80),permanent (group B, n=25) and temporary (group C,n=75) placement of expandable metallic stents. RESULTS:The diameters of the strictured GIT were significantly greater after the treatment of all procedures employed (P<0.01).For the 80 patients in group A,160 dilations were performed (mean,2.0 times per patient). Complications in group A included chest pain (n=20),reflux (n=16),and bleeding (n=6).Dysphagia relapse occurred in 24(30%) and 48 (60%) patients respectively during 6-and- 12 momth follow-up periods in group A.In group B,25 uncovered or partially covered or antireflux covered expandable metallic stents were placed permantly, complications included chest pain (n=10),reflux (n=15), bleeding (n=3),and stent migration (n=4),and dysphagia relapse occurred in 5 (20%) and 3 patients (25%) during the 6-and-12 month follow-up periods,respectively.In group C,the partially covered expandable metallic stents were temporarily placed in 75 patients and removed after 3 to 7 days via gastroscope,complications including chest pain (n=30),reflux (n=9),and bleeding (n=12),and dysphagia relapse occurred in 9 (12%) and 8 patients (16%) during the 6-and-12 month follow-up periods,respectively.The placement and withdrawal of stents were all successfully performed.The follow-up of all patients lasted for 6 to 96 months (mean 45.3±18.6 months). CONCLUSION:The effective procedures for benign GIT stricture are pneumatic dilation and temporary placement of partially-covered expandable metallic stents.Temporary placement of partially-covered expandable metallic stents is one of the best methods for benign GIT strictures in mid and long-term therapeutic efficacy.展开更多
