Study of upper gastrointestinal tract endoscopic findings in portal hypertension

The gut mucosa in portal hypertension is the seat of microcirculatory changes that compromise its integrity and increase its susceptibility to damage. The mucosal changes in portal hypertension may require pharmacological, directed endoscopic or portal decompressive therapy. The objective of the study is to find out various upper gastrointestinal tract endoscopic findings in patients of portal hypertension.

A prospective, cross-sectional, observational study of sixty patients of portal hypertension was conducted from June to October 2009. The esophagus, stomach and upper duodenum was visualized for any changes, especially by taking the tip of the instrument close to the mucosa.

Out of total, 60, 47 (78.3%) cases were cirrhotic and 13 (21.7%) cases were non-cirrhotic portal hypertension. The most frequent upper GI endoscopic finding was esophageal varices 56 (98.3%) followed by gastropathy 49 (81.6%), gastric hyperemia 19 (31.6%), duodenal hyperemia and erosive gastritis 16 (26.6% in each) and gastric varices 12 (20%). Esophageal varices were equally prevalent among cirrhotic and non cirrhotic portal hypertensive patients, 46 out of 47 (97.9%) and 13 out of 13 (100%) respectively. Gastropathy was more prevalent in cirrhotic patients with 87.2% vs. 75% in NCPF followed by 40% in EHO. However, duodenal ulcers were seen only in EHO 12.5%. Erosive gastritis was more prevalent in EHO (75%) followed by NCPF (60%), however, it was less frequent in cirrhotic portal hypertension (14.8%).

The most common upper GI endoscopic finding in portal hypertensive patients were found to be esophageal varices followed by gastropathy, peptic ulcer disease (gastric and duodenal hyperemia, chronic gastritis, erosive gastritis, gastric ulcer and duodenal ulcer).
