[The experimental heterotopic transplantation of an isolated segment of colon]

The heterotopic transplantation of isolated colon segment was achieved in the cervical region, for to study the behaviour of the colon in this new situation. The study included 20 dogs from which there were taken segments of 10 cm length from, the left colon. Then was prepared the common carotid artery, superficial jugular vein and their branches. In 5 dogs the cervical esophagus was resected. Then was performed the transplant using micro-surgical techniques. In 15 dogs the colon was exteriorized at the skin and in 5 dogs the colon was placed between the ends of the esophagus. In 76% of cases the postoperative evolution was good. From the viable colon transplants were taken fragments for histologic examinations after 1, 2 respectively 4 weeks postoperative. The results obtained, recommend the colic transplant as a possible graft for repairing the cervical esophagus defects.
