INTRODUCTION Isolated ectopic varices located in the small bowel are uncommon. Portal hypertension caused by liver cirrhosis is the most common predisposing risk factor. PRESENTATION OF CASE We present an unusual case of massive gastrointestinal bleeding from idiopathic jejunal varices in a 73-year-old Caucasian male without portal hypertension. Exploratory laparotomy disclosed ectopic varice...
Approximately one in six patients with portal hypertension who develop varices at sites of portosystemic venous collaterals has gastric varices due to hepatofugal flow into the gastric veins. Bleeding from gastric varices, though less common, has a higher mortality and morbidity compared to bleeding esophageal varices, which are easier to manage endoscopically. The efferent channel for gastric ...
background and objectives: gastrointestinal polyps are proliferative or neoplastic mucosal lesions. the most important point about these polyps is risk of malignancy of them. this study was performed to determine type and frequency of polyps of gastrointestinal tract in iranian population according to their locations. materials and methods: totally, 210 patients referred to rasul-e-akram hospi...
Esophagogastric varices are considered to be the most common complication in patients with portal hypertension. Endoscopic ultrasonography not only visualizes the surface of the varices but also provides detailed information about their internal structure. The direction of blood flow can be determined and its velocity measured only via endoscopic color Doppler ultrasonography (ECDUS). This can ...
A 68-year-old man with hemophilia A and liver cirrhosis caused by hepatitis C virus was referred to our hospital to receive prophylactic endoscopic treatment for gastroesophageal varices (GOV). He had large, tense, and winding esophageal varices (EV) with cherry red spots extending down to lesser curve, predicting the likelihood of bleeding. Esophageal endoscopic injection sclerotherapy (EIS) w...
Varices are abnormal dilated veins which result from increased pressure in the portal circulation. Although the oesophagus and stomach are the most common sites for varices to develop, they may also occur as ectopic varices in the duodenum, rectum, and retroperitoneal areas. Isolated duodenal varices involving distal duodenum, particularly the fourth part of the duodenum, are extremely rare. Ho...
Esophagogastric varices are considered to be the most common complication in patients with portal hypertension, while ectopic varices, that is, those outside of the esophagogastric region, are less common. Rectal varices represent portal systemic collaterals that are manifested as discrete dilated submucosal veins and constitute a pathway for portal venous flow between the superior rectal veins...
Ectopic varices (those outside of the gastro-esophageal region) are occasionally found on endoscopy in patients with portal hypertension; however they account for a small minority of all variceal bleeds. Cases of isolated cecal varices are quite rare and, when described, often present with acute hemorrhage or evidence of occult bleeding. We present the case of a 29-year-old male with a history ...
BACKGROUND AND OBJECTIVE Symmers periportal fibrosis secondary to schistosomiasis is a common cause of portal hypertension worldwide. Data on the prevalence of gastric varices and portal hypertensive gastropathy in this group of patients with portal hypertension is relatively scarce. The aim of this study was to determine the prevalence of gastric varices and portal hypertensive gastropathy in ...
Background and study aims Polypoid lesions found during upper gastrointestinal endoscopy (UGIE) are occasionally found in patients with portal hypertension (PH). This study aimed to assess the true nature of such polypoid lesions using endoscopic ultrasound (EUS) and determine the accuracy of UGIE in differentiating between vascular and non-vascular lesions in PH. Patients and methods We re...
