ANALYSIS OF REFLUX ESOPHAGITIS AND COLUMNAR-LINED ESOPHAGUS AFTER ESOPHAGECTOMY WITH GASTRIC TUBE RECONSTRUCTION

Abstract

[Purpose] The aim of this study was to determine the relationship between reflux esophagitis of residual esophagus (RE-re), columnar-lined esophagus of residual esophagus (CLE-re) and the acidity of the gastric tube after esophagectomy and gastric tube reconstruction for thoracic esophageal carcinoma. [Methods] RE-re was graded according to the Los Angeles classification System (LA grade). CLE-re was graded according to three grades (non CLE-re, CLE-re of a partial area (mild), CLE-re of the entire area (severe)). We performed postoperative endoscopy and measured the pH of the gastric tube under direct vision through an endoscope using a micro-pH glass electrode. [Result]The more serious the LA grade, the lower the pH value. In a similar manner, progressively lower pH values were seen with progressively serious CLE-re grade. CLE-re increased so that the LA classification was aggravated. Particularly notable was that CLE-re accounted for 66.7% of LA grade D cases. [Conclusions] The results suggested that acid in the gastric tube was related to the development of RE-re and CLE-re.
