title: [Experimental esophageal transsection. Application to the treatment of hemorrhage in portal hypertension].
abstract: Nineteen of twenty dogs undergoing experimental esophageal transection with mechanical suturing were followed up over 1 to 120 days by means of light and electron microscopy examinations to evaluate changes in suture line. Histology showed few reactions to the metallic clips, the absence of new vessel formation with early healing from the 4th day, development of collagen fascicles after 1 week and consolidation after 2 weeks with reparation by the end of 1st month. Stability of healing process was apparent between 3 and 4 months, without evidence of stenosis due to scar tissue.
