Collagen-coated vicryl mesh (CCVM) was used experimentally to patch partial and total segmental defects in the canine cervical esophagus. The esophageal healing process over a 6-month period with successful incorporation of the CCVM and esophageal wall regeneration are described. Twenty-two (91.7%) of 24 dogs survived the procedure without any evidence of esophageal stricture or dysphagia. CCVM has proved to be a suitable material for substitution of esophageal tissue in the canine model. Its clinical use in congenital and acquired esophageal lesions should be considered only pending further experimental laboratory work.
