|April 20, 2011
Summary
Inflammatory fibroid polyps, also known as Vanek's tumor, are rare causes of small bowel obstruction. This case highlights a rare instance of ileo-ileal intussusception leading to necrosis and perforation.
Area of Science:
- Gastroenterology
- Surgical Pathology
Background:
- Inflammatory fibroid polyps (IFPs), or Vanek's tumors, are rare submucosal lesions of the gastrointestinal tract.
- Intussusception caused by IFPs is uncommon, with ileo-ileal intussusception complicated by necrosis and perforation being exceptionally rare.
Observation:
- A 56-year-old woman presented with nausea, vomiting, abdominal distension, and signs of gastrointestinal perforation.
- Emergency laparotomy revealed a 17-cm invaginated mid-ileal segment with necrosis, perforation, and fecal peritonitis.
Findings:
- Surgical resection of the affected ileal segment was performed, followed by end-to-end anastomosis.
- Histopathology demonstrated an ulcerative lesion with spindle cells and significant eosinophilic infiltrate, confirmed as Vanek's tumor via immunohistochemistry.
Implications:
- This case underscores the importance of considering IFPs in the differential diagnosis of obstructive small bowel tumors, even in adults.
- Early recognition and surgical intervention are crucial for managing IFP-induced intussusception to prevent life-threatening complications like necrosis and perforation.

01:29Intestinal 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,...
01:07Intestinal 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...
01:23Anatomy of the Intestines
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...

01:24Esophageal 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...
01:21Inflammatory 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:

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
