Insights

Heterotopic gastric mucosa in the rectum caused rectal bleeding and abdominal pain in a child. Surgical removal resolved symptoms, confirming this rare condition as a treatable cause of pediatric gastrointestinal bleeding.

Area of Science:

  • Pediatric Gastroenterology
  • Surgical Pathology

Background:

  • Heterotopic gastric mucosa is rare in the rectum.
  • It can present with gastrointestinal bleeding and abdominal pain in children.

Observation:

  • A 3-year-old boy presented with rectal bleeding and colicky abdominal pain.
  • Technetium-99m pertechnetate scintigraphy showed increased uptake in the rectum and left colon.

Findings:

  • Endoscopic and histologic examination confirmed heterotopic gastric mucosa exclusively in the rectum.
  • The left colon uptake was a false positive on scintigraphy.

Implications:

  • This case highlights the importance of correlating imaging findings with endoscopic and histologic data.
  • Surgical excision is an effective treatment for symptomatic rectal heterotopic gastric mucosa in children.

Esophageal Strictures-I: Introduction01:30

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 Varices-I: Introduction01:24

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...
Esophageal Varices-II: Clinical Features and Management01:28

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...
Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Peptic Ulcer01:27

Peptic Ulcer

Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...
Pyloric Obstruction01:11

Pyloric Obstruction

Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
