ObjectiveTo improve the efficacy of colon doublecontrast barium enema examination by using digital gastrointestinal machine and modified enema techniques. MethodsSixtyfour patients were examined on digital remote controlled gyration table, with oral coloncleansing preparation and selfmade disposable plastic bag. Results In 64 patients, up to 93.8% were found with none or little fecal materials in the cecum and ascending colon. 80% of the results were scored excellent, and 95% were accurate for making diagnosis. All the patients underwent the examination successfully. ConclusionDigital gastrointestinal machine examination combined with modified hypotonic doublecontrast barium enema is a simple, convenient and efficient way to clearly demonstrate colonic mucosa, and help increase the detection and diagnosis rate.
