  • EARLY DIAGNOSTIC VALUE OF RADIONUCLIDE VISUALIZATION TO EXPERIMENTAL STRANGULATED BOWEL OBSTRUCTION

    Different types of bowel obstruction,including strangulated loop,mesenteric venous occlusions,mesenteric arterial occlusions and simple obstruction, were induced in rabbits.After induction of occlusion, imaging agent of 99mTc-pyrophosphate was injected intravenously.Thirty minutes later,abdominal plain image was successively taken with a single photon emission computed tomography (SPECT).At the same time,the uptake ratio of region of interest was determined.The results revealed that animals in strangulated loop group and mesenteric venous occlusion group had high radioactive concentration in the area of ischemic bowel. Uptake ratio of region of interest of imaging area in the two experimental group was higher than that in simple obstruction and control group.Whereas the mesenteric arterial occlusion group did not appearantly present the changes mentioned above.These showed that there was an accumulation of agent in strangulated ischemic bowel segment in strangulated loop group and mesenteric venous occlusion group.All results suggest that radionuclide visualization with SPECT could be a valuable method for early diagnosis of acute intestinal strangulation of strangulated loop type and mesenteric venous occlusion type.
