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 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...

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Intestinal Obstruction I: Introduction01:29

Intestinal Obstruction I: Introduction

Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...
Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...

Summary

A rare case of small bowel obstruction caused by amoebic infection leading to ileal stricturing is described. This highlights a critical complication of amoebiasis in the gastrointestinal tract.

Area of Science:

  • Gastroenterology
  • Infectious Diseases
  • Surgical Pathology

Background:

  • Amoebiasis is a parasitic infection primarily affecting the colon, but can manifest in other organs.
  • Small bowel obstruction is a common surgical emergency, typically caused by adhesions, hernias, or tumors.
  • Ileal stricturing is an uncommon cause of obstruction, often associated with chronic inflammatory conditions.

Observation:

  • A patient presented with symptoms indicative of small bowel obstruction.
  • Diagnostic investigations revealed a localized narrowing (stricture) in the ileum.
  • Evidence of amoebic infection was identified as the causative agent for the stricture.

Findings:

  • The stricture was pathologically confirmed to be induced by Entamoeba histolytica, a rare presentation.

  • The amoebic infection led to chronic inflammation and fibrosis, resulting in the ileal stricture.
  • Surgical intervention was required to relieve the obstruction.
  • Implications:

    • This case underscores the potential for amoebiasis to cause severe gastrointestinal complications beyond the colon.
    • Highlights the importance of considering parasitic infections in the differential diagnosis of small bowel obstruction, particularly in endemic areas.
    • Suggests a need for increased awareness among clinicians regarding the diverse clinical manifestations of amoebiasis.
