Abstract
Portal hypertensive gastrophy (PHG) is a term used to describe the endosocpic appearance of gastric mucosa with a characteristic mosaiclike pattern with or without red spots. The prevalence of PHG remained a matter of controversy. On one hand, some authors reported it to be as high as 98%. On the other hand, others reported it to be as low as 2.6%. The aim of this work is to detect the prevalence of PHG and its predictive factors. This study was conducted on 82 patients with portal hypertension. They were divided into two groups. Group I: (nonbleeders), patients without history of haematemesis or melena. group II: (bleeders), patients with history of haematemesis and/or melena. This group was subdivided into group IIa: they were followed up by endoscopic sclerotherapy, and group IIb: they were followed up by endoscopic band ligation. The endoscopy was repeated every two weeks till variceal obliteration. We found that, the prevalence of PHG was 75.6% among patients with portal hypertension. There was no difference between male and female patients or between bleeders and non bleeders. Concerning the age, there was no difference between patients with PHG and those without. PHG is predicted to be diagnosed in patients with pure posthepatitic cirrhosis with manifestation of liver cell failure, ChildPugh class B, and evident porto systemic collaterals. Also, patients with large oesophageal varices specially with red signs and those underwent endoscopic variceal management, particularly endosocpic variceal ligation, are predicted to have prevalent PHG. Again, at the Doppler ultrasonographic level, PHG is predicted to be diagnosed in the patients with splenic or epigastric collaterals, markedly increased congestion index, portal flow volume and portal cross sectional area. Also, in patients with markedly decreased portal maximum and mean velocities.
