Width of the presacral space in Nigerian adults.
The width of the presacral space and the thickness of the rectal valve were measured on lateral radiographs obtained during barium enema examinations performed on 182 Nigerian adult patients over a 5-year period (1980-1984). The mean width of the presacral space was 0.78 cm, the value in men being significantly higher than in women (p less than 0.01). Although these values are similar to those reported among Caucasians, a wider range of normal values was obtained in this study. There is also no significant difference between the mean value of the rectal valve thickness of 4.3 mm obtained in this study and that obtained from previous studies.
