TRANS-SEROSAL MULTIMODAL OPTICAL COHERENCE TOMOGRAPHY FOR VISUALIZATION OF MICROSTRUCTURE AND BLOOD CIRCULATION OF THE SMALL INTESTINE WALL

The aim of the study was to evaluate the performance of trans-serosal multimodal OCT (MM OCT) in in vivo detecting of changes in microstructure and blood circulation of the small intestine wall caused by arteriovenous ischemia resulted from intestine strangulation. Materials and Methods. In experiments on Wistar rats (n=22), we examined the small intestine wall in vivo using MM OCT; the access to the intestine was reached through laparotomy. The microvasculature and microstructure of the wall were studied before and after acute arteriovenous ischemia created by ligation of a small bowel segment. The results were then added with data ...
