Abstract Objective: Probe into the new technology of coupling gel filling and ultrasonic elastography in colorectal cancer staging’s feasibility, veracity and application value. Methods: From October 2013 to October 2014, the object of 36 patients who was colorectal cancer proctoscopy pathology confirmed intend to operative treatment is the main study, for sonography coupling gel filling ultrasonic testing, for T staging(with UT), and for making an evaluation of goiter real-time ultrasound elastography, through the retrospective analysis of ultrasonic T stage(with EUT), the postoperative pathological staging as the gold standard, analysis of two methods to colorectal cancer staging of accuracy, sensitivity and specificity is statistically significant or not. Analyze elasticity imaging and colorectal cancer staging of pertinence and sensitivity. Result: This group of cases operation pathology confirm that is colorectal cancer, on preoperative UT and EUT respectively with postoperative pathologic stage T staging consistency check, show all have good consistency(P＜0.05). The overall accuracy of the EUT to colorectal cancer staging, high sensitivity, specific degrees from UT, EUT compare UT can obviously reduce the error of low time, the difference is statistically significant(P<0.05), EUT on the diagnostic coincidence rate of progress is UT has improved significantly, the difference is statistically significant(P<0.05). Conclusion: Sonography coupling gel filling and ultrasonic elastography is a new method for evaluation of preoperative staging of colorectal cancer, is superior to the conventional intracavitary ultrasonic preoperative staging of colorectal cancer, is an effective supplementary means for preoperative evaluation of colorectal cancer staging.
