Objective  To establish interstitial cells of Cajal (ICC) loss models caused by incomplete small intestinal obstruction in rats with modified method and verify it.
Methods  Modified method was used to establish the models, making the ring around the small intestine but not through it. Morphological changes were observed by general signs, pathological changes were tested by HE staining and transmission electron microscope (TEM), and changes of ICC number were tested by immunohistochemistry staining.
Results  Success rate of this method was 56% (28/50), weight loss happened compared with before operation in ileus group (P<0.01). Hyperemia and swelling were observed in ileus group, and gastric retention was obvious. Results of HE staining and TEM showed that there was obvious inflammatory change, and ICC reduced was observed by immunohistochemistry.
Conclusion  ICC loss models caused by incomplete small intestinal obstruction meet the basic performance, and can be used for further research.
