title: [Effect of the width of excisional mucosa stoma ring on postoperative results of procedure for prolapse and hemorrhoids method].
abstract: OBJECTIVE
  To explore the effect of the width of excisional mucosal stoma ring on postoperative results of procedure for prolapse and hemorrhoids (PPH) in the treatment of hemorrhoids.
  
  
  METHODS
  Four hundred and eighty hemorrhoid patients were treated with circular stapler. Whether excisional mucosa stoma ring was regular or not, and its width were recorded. After follow-up from one month to 24 months,the outcomes were compared.
  
  
  RESULTS
  The mean age of the patients was (46.6+/- 5.1) years. Regular mucosa stoma ring was excited in 303 cases,while irregular ring in 177 cases. Hemorrhoids prolapse occurred in 18 cases of the patients with irregular mucosal ring excited, while only 8 cases of the patients with regular ring excited (P< 0.01). There was significant difference in the incidence of hemorrhoids prolapse between the different groups according to different width of excisional mucosal stoma ring (P< 0.01), and the patients with postoperative hemorrhoids prolapse was lest with the width of excisional mucosal stoma ring more than 3 cm.
  
  
  CONCLUSIONS
  The width of excisional mucosal stoma ring is one of the effecting factors of surgical outcomes. It is effective to excite mucosal stoma ring more than 2 cm,and most effective to excite mucosal stoma ring more than 3 cm.
