Purpose: To elucidate the common complications and preferred method of treatment in stricture or obstruction of gastrointestinal tract with stent insertion.
Methods and Materials: The study cohort comprised 338 cases with stricture or obstruction of the gastrointestinal tract; 348 stents were inserted, of which 303 were partially covered and 45 were uncovered.
Results: Stents were successfully placed in all 338 cases. Chest pain occurred in 63 cases (18.6%): slight or dull chest pain in 61 cases was not treated or reated by analgesia, and serious chest pain in 2 cases was treated by peridural anesthesia. Restenosis of the gastrointestinal tract in 38 cases (11.2%) was associated with tumor overgrowth in 23 cases and hyperplasia of granulation tissue in 15 cases.6 cases were inserted second stent under fluoroscopic control and 29 cases were cauterized by hot-node therapy under gastroscope guidance and 3 cases were surgically reconstructed. Reflux occurred in 40 of these cases (11.8%) after stent placement, and reflux esophagitis was managed by common antireflux measures. Stent misplacement occurred in 13 cases (3.8%). In 11 cases the stent was extracted with the aid of a gastroscope and in the other the stent was excreted from the rectum (nitinol stents) with the help of a doctor. Gastrointestinal hemorrhage in 33 cases (9.8%) was treated by hemostat. Food-bolus obstruction in 5 cases (1.5%) was treated by endoscopic removal of the bolus.
Conclusion: Common complications in stricture or obstruction of gastrointestinal tract with stent insertion were chest pain, restenosis of the gastrointestinal tract, reflux, stent displacement, bleeding, and food-bolus obstruction. Complications were treated by drugs or by second stent placement or by the gastroscope measures depanding on the specific circumstances.
