To investigate the application effects of sphincter preserving Dixon surgery combined with prophylactic ileostomy in low rectal cancer.

From July 2012 to July 2016, 62 cases of low rectal cancer treated in our hospital were retrospectively analyzed and were divided into sphincter preserving group (n=29) and combined ileostomy group (n=33) according to the operational manner. Patients in sphincter preserving group were only given low Dixon rectal surgery while patients in combined ileostomy group were given the same surgery combined with preventive ileostomy treatment. Statistical analysis were performed using SPSS statistical software 18.0, measurement data such as postoperative recovery index, anal function before surgery, 3 months and 6 months as well as postoperative life quality score were represented by (±s), compared with t test; the incidence of postoperative complications and count data were compared using the χ² test. The difference of P<0.05 was statistically significant.

Compared with sphincter preserving group, the operation time, exhaust time, recovery time, ambulation time and hospitalization time were significantly lower in combined ileostomy group (P<0.05). Besides, the anastomotic leakage rate and anastomotic stenosis rate were lower in combined ileostomy group, the differences were statistically significant (P<0.05); 3 months and 6 months after surgery, the Wexner score in the combined ileostomy group was significantly lower than in sphincter preserving group (P<0.05); 6 months after surgery, patients in combined ileostomy group had higher scores on urination, pus and blood stool, defecation frequency, exhaust defecation incontinence, incontinence and anxiety score (P<0.05).

Application of sphincter preserving Dixon surgery combined with preventive ileostomy can promote the recovery of patients in low rectal cancer Dixon rate, reduce the postoperative incidence of anastomotic fistula and other complications, improve the postoperative quality of life, which is worth application clinically.
