title: [Comparison of two-year efficacy between procedure for prolapse and hemorrhoids and Milligan-Morgan hemorrhoidectomy in treatment of III and IV degree internal hemorrhoids].
abstract: OBJECTIVE
  To compare the long-term efficacy of procedure for prolapse and hemorrhoids (PPH) and Milligan-Morgan hemorrhoidectomy (MMH) in the treatment of III and IV degree internal hemorrhoids.
  
  
  METHODS
  One hundred patients were randomly divided into two groups and received PPH (n=42) and MMH (n=58) respectively. After two years, the efficacy, complications and function of defecation were compared.
  
  
  RESULTS
  Two years after operation, the morbidities of hydrorrhea (2.38% vs 20.69%, P=0.007), dermal neoplasm formation (9.52% vs 25.86%, P=0.040) and narrowing in the caliber of the stools (2.38% vs 18.97%, P=0.027) were significantly lower in PPH group than those in MMH group (P<0.05). The morbidities of overall complication (9.52% vs 25.86%, P=0.040) and overall abnormal function of defecation (9.52% vs 29.31%, P=0.017) were lower in PPH group than those in MMH group (P<0.05). However, there were no significant differences of the morbidity of relapse (14.29% vs 10.34%, P=0.549), patient satisfactory degree (92.86% vs 87.93%, P=0.636) and overall symptom recurrence rate (19.05% vs 25.86%, P=0.424) between the two groups.
  
  
  CONCLUSIONS
  Long-term efficacies of procedure for prolapse and hemorrhoids and Milligan-Morgan haemorrhoidectomy in the treatment of III and IV degree internal hemorrhoids are similar. PPH has better safety, less complications and less effect on abnormal function of defecation compared with MMH.
