摘要 AIM:To observe the frequent complications of stent placement for stricture of the gastrointestinal tract and to find proper treatment.METHODS:A total number of 140 stents were inserted in 138 patients with benign stricture of the gastrointestinal tract.The procedure was cornpleted under fluoroscopy in all of the patients.RESULTS:Stents were successfully placed in all the 138 patients.Pains occurred in 23 patients (16.7%),slight or dull pains were found in 21 patients and severe chest pain in 2 respectively.For the former type of pain,the patients receivedonly analgesia or even no treatment,while peridural anesthesics was conducted for the latter condition. Reflux occurred in 16 of these patients (11.6%) after stent placement.It was managed by common antireflux procedures. Gastrointestinal bleeding occurred in 13 patients (9.4%),and was treated by hemostat.Restenosis of the gastrointestinal tract occurred in 8 patients (5.8%),and was apparently associated with hyperplasia of granulation tissue.In 2 patients,the second stent was placed under X-ray guidance.The granulation tissue was removed by cauterization through hot-node therapy under gastroscope guidance in 3 patients,and surgical reconstruction was performed in another 3 patients. Stent migration occurred in 5 patients (3.6%),and were extracted with the aid of a gastroscope.Food-bolus obstruction was encountered in 2 patients (1.4%) and was treated by endoscope removal.No perforation occurred in all patients.CONCLUSION:Frequent complications after stent placement for benign stricture of the gastrointestinal tract include pain,reflux,bleeding,restenosis,stent migration and food-bolus obstruction.They can be treated by drugs,the second stent placement or gastroscopic procedures according to the specific conditions.
