【Abstract】Objective To discuss how to retrieve/reset the displaced Nickel-Titanium alligation stent in upper gastrointestinal tract.Methods In this serial, the displaced upper gastrointestinal tract Nickel-Titanium alligation stent was retivere/reset in 17 cases, 18 times.Results A self produced Nickel-Titanium alligation stent reset instrument was used 4 times in displaced upper esophagus stent resetting and 2 times retrieving; It was used 3 times in displaced middle esophagus stent resetting, It was used 5 times in displaced middle esophagus stent resetting and 2 times retrieving, It also was used 2 times in displaced duodenum stent resetting. All practice did not lead to bleeding or perforation et al.Conclusion The self produced Nickel-Titanium alligation stent reset instrument is safe and efficient in retrieving/resetting the displaced Nickel-Titanium alligation stent.
