title: [Self-control study of dynamic multiple pelvic angiography and pelvic four-contrast defecography in the diagnosis of functional defecation disorder].
abstract: OBJECTIVE
  To evaluate and compare the value of dynamic multiple pelvic angiography and pelvic four-contrast defecography in the diagnosis of functional defecation disorder.
  
  
  METHODS
  From September 2014 to July 2015, a prospective controlled trial was carried out in Chengdu Anorectal Hospital. A total of 32 patients met the inclusion criteria of functional defecation disorder simultaneously underwent pelvic four-contrast defecography and dynamic multiple pelvic angiography. The diagnostic results of these two methods were compared.
  
  
  RESULTS
  The absolute values of anorectal angle and level of perineum, peritoneum and bladder from rest to defecation were (29.6±13.6)°, (26.2±14.2) mm, (55.5±25.6) mm and (28.9±16.5) mm in dynamic multiple pelvic angiography, and (24.6±5.8)° (18.7±10.6) mm, (34.5±18.4) mm and (19.2±11.8) mm in pelvic four-contrast defecography respectively, whose differences were statistically significant (P = 0.026, 0.022, 0.000, 0.011 respectively). The diagnostic rate of pelvic peritoneal hernia was 93.8%(30/32) and 68.8%(22/32) in dynamic multiple pelvic angiography and pelvic four-contrast defecography respectively with significant difference(P=0.011).
  
  
  CONCLUSIONS
  Dynamic multiple pelvic angiography has significant advantage in the diagnosis of pelvic peritoneal hernia, and can provide a more objective basis for the diagnosis of functional defecation disorder.
