Gastro-oesophageal reflux and alcoholic cirrhosis. A reappraisal.

The oesophageal pH was recorded for 3 h after a test-meal in 27 healthy control subjects (group I), 40 patients with alcoholic cirrhosis (group II), and 22 patients with a normal liver and symptoms of gastro-oesophageal reflux (control refluxers). Gastro-oesophageal reflux was observed in 10 of the cirrhotic patients. Marked reflux episodes lasted longer in cirrhotic refluxers than in control refluxers (P less than 0.05). The frequency of ascites, bleeding from ruptured oesophageal varices, peripheral neuropathy and hepatic encephalopathy were not significantly different according to presence or absence of reflux. Plasma concentrations of gastrin, somatostatin, motilin and vasoactive intestinal peptide (VIP) were measured in groups I and II. Fasting plasma motilin levels, and the release of motilin and of VIP after the meal were higher in group II than in group I. Basal levels and post-prandial profiles of the four peptides tested did not differ between cirrhotics with or without gastro-oesophageal reflux. We conclude that in patients with alcoholic cirrhosis: gastro-oesophageal reflux is frequent (25%) and characterized by prolonged reflux episodes; reflux is not correlated with the degree of liver failure and plays no significant role in the rupture of oesophageal varices; and raised plasma motilin and VIP levels cannot account for the high incidence of reflux in cirrhotics.
