Patients were divided into two groups according presence or absence symptoms prior surgery: Group A (Asymptomatic) and B (Symptomatic). Data prospectively kept electronic reports, CLO test results, histology reports changes management plan collected analysed. Results 114 included analysis, 85 (74.56%) group 29 B. detected 34 21 (p = 0.004). Those hiatus hernia (HH) (17.65% A, 44.83% B, p 0.006); stomach ulcer (7.06% 3.45% 0.676), H.pylori infection (12.86% 29.41% B).
