Dialatation of severe stricture at the site of esophago-gastric anastomosis was performed with coaxial dilator (Zeon Medical Inc) made of teflon, which was produced to dilate the bile duct stricture.
The procedure was performed in two postoperative patients who had had esophageal cancer or idiopathic esophageal rupture. The size of the stricture of the former patient was 1 mm in diameter and 3 mm in length, and that of the later was 2 mm and 15 mm, respectively. Co-axial dilator of 2 mm in diameter was inserted under fluoroscope over a guide-wire which was previously passed through the stricture by endoscope. Then co-axial dilater of 3, 4 and 5 mm in diameter were inserted in succession. Then Rigiflex baloon dilator (Microvasive Inc) and SBM baloon dilator (Sumitomo Bakelite Inc) were used further to dilate the stricture.
The anastomosis was dilated enough, and they had become able to ingest solid food. There was no symptom of restricture thereafter. Co-axial dilator was effective for the dilatation of severe esophageal stricture, especially in the cases in which dilatation technique using baloon cannot be indicated.
