"Background: Esophagitis implies an organic damage of the esophagus due to several pathophysiologic factors, predominantly: (1) degree of gastric acid secretion (gastric pH), whereabouts are rapidly or slowly to be mucosal breaks onto esophagus were under the influe nced by: (a) gastric pH 54 and (b) the contact of gastric acid into esophageal mucosal. (2) Lower esophageal sphincter (LES) as a important lactor lor antifetlux mechanisms, which antireflux mechanism cannot senre as a barrier system whenever tone of LES comes down until 510 mml-lg that causes feeble resting LES pressure. Esophageal injuries are recognized endoscopicaliy by the presence of the Savary-Millers classification (1985), but there are not definitely which ones principally to pathophysiologic factor. Methods: This was a consecutive non-random sampling cross sectional study Thirty subject from 127 patients with dyspepsia undergoing elective upper-endoscopic examination with collecting of the gastric juice and biopsies of tower esophageal mucosal, also esophageal manometric examination. Before that, clinical inclusive and exclusive criterias until laboratory examination were performed. Significant interval was 95%. Analyzing data with Fisher?s Exact Test One-Tail to correlate between gastric pH and hypotonic LES into esophagitis. Results: Esophagilis prevalence was 22. 8%. Fisher's Exact Test One-Tail to correlate esophagitis with gastric pH E 4 was significant (p=0.013798), but with hypotonic LES (tones of LES S 10 mmHg) was not (p=0.60269). The combined roles or' gastric pH and tones of LES into esophagitis are included: (1) Frequency of roles of pH E 4 and hypotonic LES are 48.2% (2) Frequency of role of pH < 4 without hypotonic of LES are 33.3%. (3) Frequency of role of hypotonic LES without pH S4 are 11. 1% and (4) Frequency of esophagitis without roles of pH $4 and hypotonic ol LES are 7.4%. Conclusions: The sum of gastric pH 5 4 and hypotonic of LES together are more than each separate factor. Onto statistically was significant between esophagitis and gastric pH, but there is no correlation with tones ol LES. So, gastric pH plays a more important role than LES."

"Latar belakang. Studi pH lambung pada pasien sirosis hati masih kontroversi Penelitian ini bertujuan untuk mengetahui adanya perbedaan pH lambung pada pasien sirosis hati dengan gastropati hipertensi portal GHP ringan dan berat. Metode Penelitian. Potong lintang dengan cara konsekutif pada pasien yang datang ke poliklinik gastro enterologi dan hepatologi RSCM pada periode Maret - Mei 2014 sebanyak enam puluh dua pasien sirosis hati dengan GHP dilakukan pemeriksaan endoskopi untuk menilai derajat gastropati sesuai klasifikasi McCormack dan pemeriksa pH lambung dengan menggunakan pH meter. Hasil. Dari 62 subjek didapatkan 50 subjek 80 6 berjenis kelamin laki laki dan perempuan 12 subjek 19 4 GHP paling banyak disebabkan oleh hepatitis C 56 5 hepatitis B 32 3 non hepatitis 8 1 dan alkohol 3 2 Rerata pH lambung pada seluruh pasien sirosis hati dengan GHP adalah 2 13 Rerata pH lambung pada pasien sirosis hati dengan GHP ringan 2 00 lebih rendah dibandingkan kelompok GHP berat 2 25 dengan perbedaan yang bermakna.

Background. Studies show gastric pH in cirrhosis patient still in controversy Aim of this study to know differences of gastric pH in liver cirrhosis patient withmild and severe portal hypertensive gastropathy

Methods. Cross sectional method with consecutive to all liver cirrhotic patientwho came to gastroenterology and hepatology clinic in Ciptomangunkusumo hospital Sixty two liver cirrhosis patients with portal hypertensive gastropathyunderwent endoscopy to measure degree of gastropathy based on McCormack classification and measured mean basal gastric pH with pH metry.

Result. There are 50 male subject 80 6 and 12 female subject 19 4 participating in this research Portal hypertensive gastropathy mostly caused by hepatitis C 56 5 hepatitis B 32 3 non hepatitis 8 1 and alcohol 3 2 Mean of gastric pH in all liver cirrhosis patient with portal hypertensive gastropathy was 2 13. The mean gastric pH in liver cirrhosis patient with mildportal hypertensive gastropathy 2 00 mEq L lower than the gastric pH in severeportal hypertensive gastropathy 2 25 mEq L with significant differences."
