Lung allografts with and without omentopexy in canines--bronchofiberscopic and histologic observation of bronchial anastomosis healing.

An endoscopic evaluation of the effects of omental wrapping around the bronchial anastomosis of lung allografts in an early post-transplant phase, was performed in 13 mongrel dogs. Disruption or marked stenosis of the anastomotic portion was bronchofiberscopically observed more frequently in dogs without omental wrapping than in dogs with omental wrapping and the above findings were later confirmed histologically by light microscopic observation.
