Tu1640 Is ‘Push’ an Effective and Safe Method for Relief of Esophageal Food Bolus Obstruction on Endoscopy?

we investigated subjects who underwent upper gastrointestinal endoscopy at our university since November 2007 until September 2011. We investigated a prevalence of GA by endoscopy and divided into two groups (GA( ) and GA( ) group). Between GA( ) group and GA( ) group, we investigate the characteristics(age, sex, alcohol intake and smoking) and upper gastrointestinal disorder (reflux esophagitis, Barrett’s mucosa, hiatus hernia and atrophic gastritis). A multiple logistic regression was used to assess the clinical characteristic of GA. Result: 582 cases were analyzed in this study. GA was diagnosed in 462 cases (78.4%) endoscopically. (GA( ) group: n 462, M/F 60.1%/39.9%, mean age 63.1 11.5 years, smoking 189(40.8%), alcoholic drinker 227(49.2%). GA( ) group: n 120, M/F 26.9%/73.1%, mean age 58.3 16.3 years, smoking 22(18.1%), alcoholic drinker 23(19.0%)). Between GA( ) and GA( ) group, the prevalence rate of upper gastrointestinal disorder (reflux esophagitis, Barrett’s mucosa, hiatus hernia and atrophic gastritis) were 54.5% vs 18.6%, 70.8% vs 43.6%, 40.2% vs 27.8% and 34.7%vs 39.8%, respectively. By a multiple logistic regression, Age (p 0.05, OR: 1.747 (1.010 95%CI 3.02)), male (p 0.05, OR: 3.334 (1.885 95%CI 5.895)), reflux esophagitis (p 0.05,OR: 3.564 (1.859 95%CI 6.835) and Barrett’s mucosa (p 0.05,OR: 2.757 (1.859 95%CI 4.786)) were associated with GA. Conclusion: It was considered that age, male, reflux esophagitis and Barrett’s mucosa were associated with GA. This result revealed that the GA associated clearly with gastro-esophageal reflux disease.
