Transperineal ultrasound in evaluation of the degree of rectal prolapse in females with rectal prolapse disease / 中国医学影像技术

ABSTRACT

Objective: To investigate the value of transperineal ultrasound in evaluation of the degree of rectal prolapse in females with rectal prolapse disease. Methods: Totally 26 women with rectal prolapse disease were divided into internal rectal prolapse (IRP) group (n=18) or external rectal prolapse (ERP) group (n=8) according to whether rectal prolapsed outside the anus or not. Meanwhile, 20 healthy women were selected as control group. All subjects underwent transperineal ultrasound. The position of rectum ampulla, rectal motility, the size of the pelvic diaphragm hiatus and anorectal angulation were measured at rest state and during straining and compared among 3 groups. Results: Compared with those at resting state, the size of the pelvic diaphragm hiatus increased and the position of rectal ampulla decreased in 3 groups during straining (all P0.05). Rectal motility in IRP group and ERP group were higher than that in control group (both P0.05). Conclusion: Transperineal ultrasound can be used to evaluate the degree of rectal prolapse in females with rectal prolapse disease.
