An Experimental Study on the Mucosal Epithelization of the Digestive Tract in the Dog

개의 소화관점막 재생에 관한 외과적 연구

This study was performed for the purpose of investigating the possibility of epithelization on the defect of digestive tract after covering it with serosal wall of the cecum in the dog. The results obtained were as fallows: 1. Each defect of the digestive tract revealed almost complete formation of the mucous membrane and the muscle. Especially it was most fast in the jejunum. 2. Fistula formation was not found in all the experimental cases. The defects of small intestine and large intestine near the cecum were healed more fastly than the other portion. 3. The stomach and the duodenum appeared intestinal adhetion more frequently than the jejunum and the colon. Therefore, it is considered that covering with serosal wall of the cecum in the lower intestine is far better than in the upper intestine.
