We evaluated a pre-tinning leukocyte labeling technique using Glucoheptonate-Sn lyophilized kit, in the detection of activity in 15 patients with clinical and laboratory signs of active inflammatory bowel disease (IBD). 25 patients, without gastrointestinal disease were the control group. In 7/8 patients with Crohn's disease and in 7/7 with Ulcerative Colitis the study was positive. The negative study corresponded to a patient who has only involvement of the duodenum, an area of difficult evaluation due to the high liver uptake. 3/25 patients of the control group had activity in the intestine at 4 hour images. In spite of the small group evaluated, we believe that this labeling technique is a promising procedure for evaluation of activity in patients with IBD (Sensitivity 93.3%, Specificity 88.0%).

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D011877 Radionuclide Imaging The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D003093 Colitis, Ulcerative Inflammation of the COLON that is predominantly confined to the MUCOSA. Its major symptoms include DIARRHEA, rectal BLEEDING, the passage of MUCUS, and ABDOMINAL PAIN. Colitis Gravis,Idiopathic Proctocolitis,Inflammatory Bowel Disease, Ulcerative Colitis Type,Ulcerative Colitis
D003424 Crohn Disease A chronic transmural inflammation that may involve any part of the DIGESTIVE TRACT from MOUTH to ANUS, mostly found in the ILEUM, the CECUM, and the COLON. In Crohn disease, the inflammation, extending through the intestinal wall from the MUCOSA to the serosa, is characteristically asymmetric and segmental. Epithelioid GRANULOMAS may be seen in some patients.
