Abstract：Objective To study the changes of anorectal function of patients suffered from rectal cancer af-ter conducting ultra-low rectal anastomosis. Methods 32 patients who received ultra-low rectal anastomosis were retrospectively analyzed. The anorectal pressure measurement and XUZHONGFA AnaJ—Function’ s crite-ria were used respectively to evaluate the preoperative anorectal function and its function 3 months, 6 months and 12 months after operation. Results The anal resting pressure(ARP), the maximal squeezing pressure (MSP) and the maximal squeezing time(MST) of the 3rd and the 6th month were significantly lower than that of preoperative data (P<0. 01);but these indexes of the 12th month have no obvious difference with the preop-erative(P>0. 05). 3 months after surgery, the rectoanal inhibitory reflexes (RAIR) of 78% (25/32)patients were absent;12 months after surgery, 81% (26/32)patients restored RAIR. Patients were hard to handle defe-cation at early period postoperation (fine/excellent rate 18. 8%) and most patients increased their anal function 12 months after the surgery ( fine/excellent rate 75%) . Conclusions The anorectal function impaired obvious-ly at early postoperative period, and it was restored in most patients gradually. Anus-preserving operation is fea-sible and practical for patients who suffered from rectal cancer.
