[Repair of duodenal defects by a pedunculated jejunal flap. Experimental study in the dog (author's transl)].

The authors operated 18 dogs on whom they carried out a large duodenal defect which was then repaired, in the same operation, by an open pedunculated jejunal flap. They studied the progress of this flap and the quality of the duodenal repair. After about 4 months, on average, the animals were re-operated to check the quality of the repair and to see if the vascular peduncle could be cut. Section of the vasculature was well tolerated because of the development of very small vascular anastomoses.
