Esophageal varices and portal hypertensive gastropathy are the common manifestations of portal hypertension. Portal hypertensive duodenopathy is an uncommon feature of the portal hypertension syndrome.  Endoscopic and histopathologic findings of portal hypertensive duodenopathy are not well described. Herein, we report a case where portal hypertensive duodenopathy presented as multiple sessile polyps.
A 55-year-old male with a known case of alcoholic cirrhosis was admitted with progressively increasing jaundice and ascites. He had variceal bleeding 2 years ago. On physical examination, he had jaundice and ascites. Laboratory investigations revealed elevated liver enzymes and bilirubin. Endoscopy showed grade II esophageal varices and moderate portal gastropathy. In addition, multiple sessile polyps were seen in the first part of the duodenum, which was biopsied [Figure 1]. The histopathologic examination of the specimen showed polypoid mucosa covered by small intestinal and gastric foveolar types of epithelium. The lamina propria showed proliferating ectatic capillaries [Figure 2]. Fibrosis and smooth muscle in the lamina propria were noted focally along with inflammation. A diagnosis of portal hypertensive duodenopathy was given.
Portal duodenopathy perhaps is the least common gastrointestinal manifestation of portal hypertension syndrome. Only a few studies exist in the literature on the endoscopic and microscopic features of this entity. Endoscopic findings described in portal duodenopathy include erosions, ulcers, friability of the mucosa, edema, and solitary polyp, erosions and ulcers being the most common.  There has been one report of a solitary duodenal polyp, by David et al.  Multiple sessile polyps in the duodenum as in the present case have not been reported so far.
Angiogenesis, congestion, edema, apoptosis, fibrosis, and villous change are the microscopic features described in portal hypertension. Angiogenesis (neovascularization) is an important vascular phenomenon that mediates adaptation and accommodation of the high portal pressure.  The present case showed crowding of capillaries in the lamina propria and fibrosis. Gastric metaplasia was observed in addition, which suggested the possibility of a coexisting Helicobacter pylori gastritis.
In conclusion, this case represents a rare gastrointestinal manifestation of portal hypertension with unusual endoscopic findings of multiple sessile duodenal polyps and a microscopic picture diagnostic of portal duodenopathy.
