Abstract:
Objective To investigate the differences in the survival time and the occurrence of complications between esophageal cancer patients treated with fully-covered segmented esophageal internal irradiation stent and esophageal cancer patients treated with conventional esophageal internal irradiation stent.Methods The clinical data of 66 esophageal cancer patients,who had received esophageal internal irradiation stents placement,were retrospectively analyzed.The patients were divided into the study group (using fullycovered segmented esophageal internal irradiation stent,n=30) and the control group (using conventional esophageal internal irradiation stent,n=36).The postoperative complications,including restenosis,stent migration,chest pain,etc.,and the survival time of the two groups were recorded.The results were analyzed,and P＜0.05 was considered to be statistically significant.Results No statistically significant difference in the restenosis rate existed between the study group and the control group (20.0％ vs.30.6％,P=0.403);although the median time of restenosis in the study group was longer than that in the control group (161.5 d vs.138 d,P=0.025).The stent migration rate in the study group was higher than that in the control group (33.3％ vs.8.3％,P=0.014).The difference in the median time of stent migration between the two groups was not statistically significant (91.5 d vs.166 d,P=0.236).No statistically significant difference in the median survival time existed between the two groups (186 d vs.178 d,P=0.486).No statistically significantly differences in the incidence of other stent-related complications existed between the two groups.Conclusion Fully-covered segmented esophageal internal irradiation stent can delay the occurrence of restenosis,although it can increase the stent migration rate to a certain degree.
