Esophageal Strictures-I: Introduction

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Esophageal Varices-I: Introduction

Esophageal Varices-I: Introduction

Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Barrett Esophagus-I: Introduction

Barrett Esophagus-I: Introduction

Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...

Upper GI Series: Barium Swallow

Upper GI Series: Barium Swallow

The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Esophageal Varices-II: Clinical Features and Management

Esophageal Varices-II: Clinical Features and Management

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...

Summary

This summary is machine-generated.

Adults can rarely experience gastric outlet obstruction due to duodenal webs. This case highlights a potential link between NSAIDs, like diclofenac, and duodenal web formation in older patients.

Area of Science:

Gastroenterology
Digestive Diseases
Surgical Pathology

Background:

Duodenal webs typically cause gastric outlet obstruction in infants.
Adult presentation of duodenal webs is uncommon but can occur.

Purpose of the Study:

To report an unusual case of adult gastric outlet obstruction caused by duodenal webs.
To discuss potential etiological factors for duodenal webs in adults.

Main Methods:

Case report of an 82-year-old woman with gastric outlet obstruction.
Diagnostic workup included CT scan and upper gastrointestinal endoscopy.
Endoscopic dilation of duodenal webs was performed.

Main Results:

Duodenal webs were identified as the cause of gastric outlet obstruction.
Endoscopic dilation of the webs was successful.
Carcinoma and peptic stricture were initially suspected but ruled out.

Conclusions:

Duodenal webs are a rare cause of gastric outlet obstruction in adults.
Incomplete endoscopic visualization of the duodenum can lead to missed diagnoses.
Nonsteroidal anti-inflammatory drugs (NSAIDs) and slow-release potassium tablets may contribute to duodenal web formation.
