Drug retention enema is a common therapy for various illnesses. However, it is impossible to keep the drug in the colon for a long time, due to the limitation of the current equipment, and it is unable to achieve the purpose of retention enema. A retention enema device was designed by the department of intensive care unit (ICU) of Dongfeng Hospital Affiliated to Hubei University of Medicine. The retention enema device adds a spindle shaped inflatable air bag on the basis of the traditional enema device, which not only fix on the anus, but also prevent the leakage of enema fluid. It can achieve retention enema, play the enema drug effect fully, and significantly reduce the nursing workload, in addition, the silica gel material of the retention enema device ensures the comfort of the patients, the decompression air bag also avoids the damage of the high pressure of the spindle fixed air bag for the patients, which is worthy of clinical use.

Recently, the availability of multidetector-row CT (MDCT) and continuous refinement in three-dimensional (3D) imaging process have greatly expanded the role of CT in evaluating patients with gastrointestinal diseases. MDCT is the latest advancement in CT technology and is now more readily available. This imaging modality can offer full examination of the entire intestinal tract as well as powerful information about the bowel itself and its surrounding structures, which are inherent advantages of CT over conventional barium or optical endoscopic studies. In most cases, MDCT with various 3D technologies can make an easy, rapid, and accurate diagnosis by one-stop imaging, and enables to avoid other examinations. Therefore, knowledge and awareness of valuable clinical applications and proper scan technique of MDCT imaging is essential to achieve the diagnostic goal of one-step imaging.
