A new technic of the barium enema was proposed for the better colonic double contrast study with the average 204 ml of 50 w/v % barium, applied to 109 serial patients. The barium was introduced to sigmoid colon, and then pushed to a mid transverse colon by the air insufflation through an enema syringe, a new device. An advance to cecum is accoplished by the air insufflation and/or the position change of the patient. The aarium transfer method was developed for the best spot film exposure, through colon, by the position change of the patient, the tilting of the x-ray table and the air insufflation with the enema syringe. The mean angle of the x-ray table tilted was -10$^{circ}$ at the beginning the barium enema till the barium sent past the splenic flexure, -15$^{circ}$ for the best lateral view of rectum and -18$^{circ}$ for the bet pron PA view of rectosigmoid colon. This was a simple, better and economic double contrast barium enema for the cooperative patients.
