Efficacy Of Esophageal Stenting Versus Simple Dilatation For Refractory Benign Esophageal Stricture Can Be Performed

Objective:to summarize the refractory benign esophageal stenosis classification,comparison and treatment of refractory benign esophageal stenosis take simple expansion into remoable esophageal stent type treatment effect,to discuss different types of the treatment of refractory benign esophageal stenosis should be paid attention to when the choice problem.Method choice:choose refractory benign esophageal stenosis patients as the research object,a total of 46 cases,including 22 cases with stomach anastomotic stricture after the surgery,postoperative esophageal stent placement granulation or hyperplastic scar restenosis in 11 cases,endoscopic mucosal stripping postoperative esophageal stenosis(3 cases),esophageal chemical burns caused stenosis in 2 cases,local radiation result in 8 cases of esophageal stenosis;Depending on the length of the narrow,narrow length of 20 patients with less than 1 cm length of narrow 1-4 cm 26 cases.Before treatment to the patients and their families in this paper,the esophageal stricture dilatation and placement remoable esophageal stent type two kinds of advantages and disadvantages of different treatment and the possible treatment effect,according to the choice of treatment in patients with grouping,divided into the esophagus expansion treatment group and esophageal stent in treatment group,treatment group under endoscopic esophagus expansion using silica gel bougie dilator appropriate expansion treatment,esophageal stent in treatment group take placement under endoscope assisted remoable esophageal stent type memory alloy.After treatment were followed for 1 month,2 months and 4 months of anastomotic diameter,degree of difficulty swallowing and complications such as change.Results:15 cases of patients with esophageal dilatation therapy alone,a line of 31 patients and placed remoable esophageal stenosis expansion type memory alloy esophageal stent(in remoable esophageal stent placement success after 4 weeks).Choice of 15 patients with esophageal dilatation therapy in expansion of postoperative esophageal stenosis by preoperative +/-1.0 mm to 3.4 mm in diameter of postoperative 1 month 10 mm ±-1.6 mm,9 ±-1.2 mm,2 months after 4 months after esophageal stenosis 7 ±-1.4 mm in diameter,dysphagia to improve for level 3 from 4.Successfully placed remoable esophageal stent type 31 cases,30 cases in place remoable esophageal stent type 4 go esophageal stent to use in esophageal stricture by preoperative postoperative 1 month ±-1.0 mm to 3.4 mm to 14.8 mm + 1.6 mm,2 months after esophageal stenosis diameter of 11.5 mm ±-1.3 mm,11.12 ±-0.8 mm,4 months after esophageal stenosis diameter dysphagia to improve levels of 1 + 1 from level 4;1 patients in 2 weeks after esophageal stent placement esophageal stent displacement line of esophageal stents,use in esophageal stricture by 3.4 mm and 1.0 mm to 14 mm,postoperative dysphagia to improve to level 2 by 4.In this study,by esophageal perforation after 0,0 cases of gastrointestinal bleeding,15 cases of chest pain,gradually alleviate medicine 2 to 7 days later.Conclusion:the conclusion according to the causes of refractory,benign esophageal stricture and imaging characteristics,choose a different treatment,ideal therapeutic effect can be obtained.
