AIM:To determine the most effective intervention procedureby evaluation of mid and long-term therapeutic efficacy inpatients of stricture of the gastrointestinal tract (GTT).METHODS:Different intervention procedures were usedto treat benign stricture of GIT in 180 patients includingpneumatic dilation (group A,n=80),permanent (group B,n=25) and temporary (group C,n=75) placement ofexpandable metallic stents.RESULTS:The diameters of the strictured GIT weresignificantly greater after the treatment of all proceduresemployed (P<0.01).For the 80 patients in group A,160dilations 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 in24(30%) and 48 (60%) patients respectively during 6-and-12 momth follow-up periods in group A.In group B,25uncovered or partially covered or antireflux coveredexpandable metallic stents were placed permantly,complications included chest pain (n=10),reflux (n=15),bleeding (n=3),and stent migration (n=4),and dysphagiarelapse occurred in 5 (20%) and 3 patients (25%) duringthe 6-and-12 month follow-up periods,respectively.In groupC,the partially covered expandable metallic stents weretemporarily placed in 75 patients and removed after 3 to 7days via gastroscope,complications including chest pain(n=30),reflux (n=9),and bleeding (n=12),and dysphagiarelapse occurred in 9 (12%) and 8 patients (16%) duringthe 6-and-12 month follow-up periods,respectively.Theplacement and withdrawal of stents were all successfullyperformed.The follow-up of all patients lasted for 6 to 96months (mean 45.3±18.6 months).CONCLUSION:The effective procedures for benign GITstricture are pneumatic dilation and temporary placementof partially-covered expandable metallic stents.Temporaryplacement of partially-covered expandable metallic stentsis one of the best methods for benign GIT strictures in midand long-term therapeutic efficacy. AIM: To determine the most effective intervention procedure by evaluating mid and long-term therapeutic efficacy in patients of stricture of the gastrointestinal tract (GTT). METHODS: Different intervention procedures were used to treat benign stricture of GIT in 180 patients including pneumatic dilation (group A, The diameters of the strictured GIT weignificantly greater after the treatment of all procedure advanced (P <0.01) were significantly higher than those of the permanent (group B, n = 25) and temporary .For the 80 patients in group A, 160dilations were performed (mean, 2.0 times per patient) .Complications in group A included chest pain (n = 20), reflux (n = 16), and bleeding 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 coveredexpandable metallic stents were placed permantly, complications included chest pain (n = 10), reflux (n = 15), b and leptin migration (n = 3), and stent migration (n = 4), and dysphagia occurred in 5 (20%) and 3 patients (25%) during the 6-and-12 month follow- Partial covered metallic stents were tentatively 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 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 CONCLUSION: The effective procedures for benign GITstricture are pneumatic dilation and temporary placementof partially-covered expandable metallic stents. Temporary placement of partially-covered expandable metallic stents. one of the best methods for benign GIT strictures in mid and long-term therapeutic efficacy.
