Portal hypertensive polyps (PHPs) are more common than previously thought and often misdiagnosed. Previous rubber band ligation and increased liver stiffness are linked to their appearance.
Area of Science:
- Gastroenterology
- Hepatology
- Pathology
Background:
- Portal hypertensive polyps (PHPs) are uncommon gastric lesions associated with portal hypertension.
- Their clinical factors and prevalence are not well-established.
Purpose of the Study:
- To determine the prevalence of PHPs in cirrhotic patients.
- To identify clinical factors associated with PHP appearance.
Main Methods:
- A cross-sectional study of 513 cirrhotic patients.
- Descriptive analyses and multivariable logistic regression were used.
- Multiple imputation addressed missing data for HVPG and liver stiffness.
Main Results:
- PHP prevalence was 3.3%, with 53% misclassified during initial gastroscopy.
- Patients with PHPs were older and had higher HVPG, liver stiffness (TE), and prior RBL.
- Multivariable analysis showed RBL (OR 3.84) and liver stiffness (OR 1.03) significantly correlated with PHPs.
Conclusions:
- PHP prevalence is higher than previously reported, with frequent misclassification.
- PHPs are associated with prior RBL and may indicate severe portal hypertension.
- PHPs could serve as a marker for significant portal hypertension, though their clinical significance requires further study.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
