UNLABELLED: A number of physiologic and radiologic investigations are used in investigating defecation disorders. Defecography is one important part of these investigations. However, a correct diagnosis of an enterocele is sometimes difficult despite use of contrast media in the rectum, vagina, and small bowel.
PURPOSE: This study was undertaken to ascertain if it was technically possible to perform simultaneous defecography and peritoneography in an effort to improve the diagnostic possibilities in patients with defecation disorders.
METHODS: Twelve patients with defecation disorders and an unexplained widening of the rectovaginal space at defecography were investigated. Contrast medium was introduced intraperitoneally, after which conventional defecography was performed.
RESULTS: All investigations were carried out without complications and demonstrated the peritoneal outline in all patients. Simultaneous defecography and peritoneography differentiated between an enterocele and a pathologically deep pouch of Douglas--a peritoneocele. Three types of peritoneocele were visualized: vaginal peritoneocele, septal peritoneocele, and rectal peritoneocele with or without enterocele. Combinations of the three types were also found. Eight of the 12 patients had rectal intussusception or rectal prolapse. All of these eight patients had a rectal peritoneocele.
CONCLUSIONS: Simultaneous defecography and peritoneography can be performed without technical difficulties or complications. Peritoneal outlines and pouches can, therefore, be studied directly during the act of defecation. An unexplained widening of the rectovaginal space at defecography can be clarified as a peritoneocele, with or without an enterocele. Peritoneocele can be of three different types: rectal, septal, or vaginal.
