To sum up the key points of disposable anorectal stapling technique PPH to complete the super low rectal cancer coloanal anastomosis, and to analyze the clinical effect of sodium phosphate oral solution in anus preserving operation for low rectal cancer in the bowel preparation.

Sixty-nine cases of low rectal cancer in Zhuozhou City's Hospital from May 2011 to June 2012 were, in accordance with the digital meter, randomly divided into experimental group (35 cases) and control group (34 cases), respectively. The experimental group was given oral sodium phosphate solution, and the other group oral castor oil. PPH devices were used to complete the ultra-low rectal cancer colon anal anastomosis. Comparison of the two groups was carried out on such clinical data as preoperative preparation time, postoperative symptoms, midgut wall edema, bleeding, intestinal cavity cleanliness, and postoperative intestinal recovery time, diarrhea index.

The 69 operations were smooth. As for preparation time, intraoperative symptoms, wall edema, and postoperative recovery, the experimental group was better than control group (P<0.05); but in the intraoperative blood loss, postoperative intestinal cavity clean, and diarrhea, there was no statistically significant difference between the two groups.

The time of sodium phosphate oral solution for bowel preparation is short; there is less intraoperative wall edema, better cleaning effect, and the time for postoperative intestinal recovery is short. The less adverse reaction, safety and effect are worth the clinical promotion.
