Lower esophageal sphincter pressure in cirrhotic men with ascites: before and after diuresis
Abstract:
Lower esophageal sphincter pressure (LESP) was measured in 10 biopsy-proved cirrhotics with esophageal varices and tense ascites before and after diuresis to evaluate of ascites might play in the development of variceal bleeding. In the 10 cirrhotic men studied, basal LESP was 30.9 +/- 1.7 mm Hg before and 22.7 +/- 1.3 mm Hg (P less than 0.01) after a diuresis which resulted in a mean 12-kg weight loss. LESP responses to abdominal compression were also evaluated. The change in LESP in response to a standard degree of abdominal compression was greater in the presence of ascites (8.5 +/- 0.4) than in its absence (6.3 +/- 0.4) (P less than 0.01). Basal gastric pH and fasting plasma gastrin concentrations did not differ during the two testing periods. Based on these data and the rarity with which cirrhotic patients with ascites complain of heartburn, it is concluded that reflux esophagitis caused by failure of the lower esophageal sphincter to remain competent is unlikely to be a significant etiological factor in the development of variceal bleeding.
