Abstract：Objective To observe the clinical effects of tissue-selecting therapy stapler（TST）combined with extemal hemorrhoidectomy in treating severe mixed hemorrhoids.Methods 156 mixed hemorrhoids patients from July 2014 to August 2015 of our hospital were selected as study objects.The patients were divided into observation group and control group.Each group was 78 cases.Patients in observation group were used TST combined with extemal hemorrhoidectomy，and patients in control group were used procedure for prolapseand hemorrhoids（PPH）.The treatment effects and incidence rate of complications in two groups were compared.Results The cure number of observation group was 72 and the cure rate was 92.31%，obviously higher than that was 80.77%in control group with statistical difference（P＜0.05）.The operation time of observation group was shorter than that of control group，bleeding volume during operation was less than that of control group and VAS score of observation group were obvious lower than that of control group，with statistical difference（P＜0.05）.The four complications incidence liked anal pendant expansion，anorectal stenosis，abnormal bleeding and edema of anal edge，the total incidence rate of complications in observation group was 15.38%，far lower than 46.15%in control group，with statistical difference（P＜0.05）.Conclusion TST combined with extemal hemorrhoidectomy has more ideal clinical effects than PPH treatment，which can obviously decrease complications and is worth to popularize in clinic.
