The purpose of this study was to investigate the clinical significance of FH detection of rectal mucosal exudates in the evaluation of local curative efficacy of non-operative rectal cancer.

A total of 36 patients with non-surgical rectal cancer from December 2016 to December 2017 were selected for rectal mucosa percolation FH test and colonoscopy before, during and after treatment. The results of colonoscopy were analyzed using SPSS17.0 software, and the results of colonoscopy and FH were compared using chi-square test. The Kappa consistency coefficient test was used to examine the correlation and consistency of the test results of the two detection methods, and P<0.05 was statistically significant.

The detection rate of rectal mucosa percolation FH test and colonoscopy before, during and after treatment was 97.2%; 100%; 55.6% and 66.7%; 27.8%; 33.3%; all P>0.05, the difference was not statistically significant. The positive predictive values of FH before, during and after treatment were 91.8%, 93.0% and 94.7%. The Kappa consistency coefficient was 0.769 and 0.870 respectively, and all P<0.0001.

FH detection of rectal mucosal exudate and colonoscopy in the evaluation of local curative effect of non-operative rectal cancer is equivalent, which is expected to provide a more simple and rapid index for the evaluation of curative effect of non-operative rectal cancer.
