title: [Efficacy of retained rectal posterior mucosa in procedure for prolapse and hemorrhoids].
abstract: OBJECTIVE
  To evaluate the efficacy and necessity of retained rectal posterior mucosa in procedure for prolapse and hemorrhoids (PPH).
  
  
  METHODS
  Clinical data of 260 cases with severe hemorrhoids in our hospital from January 2010 to May 2012 were analyzed retrospectively. A total of 132 cases with severe hemorrhoids excluding in rectal posterior wall were enrolled in retained rectal posterior mucosa in PPH (improvement group), other 128 cases of severe hemorrhoids were assigned to PPH (conventional group). Operative parameters, efficacy and complication after operation were compared.
  
  
  RESULTS
  Two groups of patients received successful operations. Postoperative pain duration, frequency of analgesic drugs and postoperative hospital stay in improvement group were significantly reduced [(1.3 ± 0.5) d vs. (4.8 ± 0.7) d, 1.1 ± 0.3 vs. 5.9 ± 0.6, (5.2 ± 0.8) d vs. (5.8 ± 0.5) d, all P<0.01]. Incidence of anastomotic stenosis, heavy feeling in the anus and delayed bleeding in improvement group were significantly lower than those in conventional group (0 vs. 7.8%, 0.8% vs. 14.1%, 0 vs.7.8%, all P<0.01).
  
  
  CONCLUSIONS
  The application of retained rectal posterior mucosa in PPH to patients with severe hemorrhoids excluding in rectal posterior wall can significantly reduce postoperative complications. But long-term efficacy needs further observation.
