Abstract:

【Abstract】 Objective To investigate the efficacy of TST (tissue-selecting therapy stapler) in the treatment of severe prolapsed hemorrhoids. Methods Fifty-eight cases with Ⅲ or Ⅳ degree hemorrhoids were operated by TST procedure and 60 cases were operated by PPH. The operative effects were analyzed comparatively. Results Blood loss in PPH group and TST group were 18.55±3.19 mL and 10.17±2.82 mL, and there was significant difference between two groups (P<0.05). VAPS score in PPH and TST group were 1-3 and 4-6, and the differences were significant between two groups. However, the anal resting pressure and rectal resting pressure had no significant difference before and after operation. All the patients were followed-up for 6 mouths. No case had anal stenosis, infection or perianal abscess. Conclusion In the curative effects, TST is similar to the PPH  procedure in the treatment of severe prolapsed hemorrhoid and it has safety, reliable, lower complications and less blood loss.
