Observation and nursing of anorectal manometry on super-low rectal cancer patients with ISR in perioperative period

Objective To evaluate the defecation function after intersphincter resection (ISR) of super - low rectal cancer and study the nursing methods of anorectal manometry, in order to ensure the effectiveness of ISR. Methods Anorectal rnanometry was used for testing 30 patients with super - low rectal cancer who under ISR before and after operation, After evaluating the pressure of enteric cavity and the rehabilitation of defecation function after operation, relevant nursing was provided according to Williams' standard. Results Anal canal resting pressure was greatly lower after operation (P <0. 01 ) . Maximum squeeze pressure and maximum tolerance of the rectum were greatly reduced ( P < 0. 01 ) and restored gradually in course of time but not to normal. Abolition of rectal anal inhibitory reflex was appeared in most patients after operation (3/30) and restoration of rectal anal inhibitory reflex was not obvious. According to the defecation of Williams'standard, 86.7 %, 93.3 %, 96.7 % of the patients received good effect in defecation function after 3, 6 and 12 month respectively. Conclusions After testing anal canal resting pressure precisely before and after operation and doing well in nursing of the manometry,nursing measures according to the evaluation of resting pressure and defecation function are adjusted. And it is helpful for rehabilitation of defecation function. Key words: Super-low rectal cancer; Defecation function; Anorectal manometry; Nursing
