Insights

Adult intussusception, though rare, often presents with vague symptoms. This case highlights an unusual cause: a small intestinal angiolipoma leading to ileoileal intussusception in a young woman.

Area of Science:

  • Gastroenterology
  • Surgical Pathology

Background:

  • Intussusception is uncommon in adults, typically presenting with chronic, non-specific symptoms of partial obstruction.
  • Unlike pediatric cases with a classic triad, adult intussusception often lacks distinct signs.
  • Neoplasms are frequent causes of adult intussusception, acting as the lead point.

Observation:

  • A 29-year-old woman presented with subacute symptoms suggestive of intestinal obstruction.
  • Imaging revealed ileoileal intussusception, a rare form of bowel telescoping.
  • The lead point was identified as a polypoid submucosal angiolipoma.

Findings:

  • Angiolipomas, benign tumors of adipose tissue and capillaries, are exceptionally rare in the small intestine.
  • This case details an angiolipoma as the etiology for adult intussusception.
  • The patient's presentation was atypical for adult intussusception.

Implications:

  • This case underscores the importance of considering rare benign lesions in the differential diagnosis of adult intussusception.
  • It highlights the variability in clinical presentation of adult intussusception.
  • Further research into rare small intestinal tumors and their presentations is warranted.

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,...
Histology of the Small Intestine01:27

Histology of the Small Intestine

The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
Appendicitis01:19

Appendicitis

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...

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:
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...
Diverticular Disease of the Colon01:27

Diverticular Disease of the Colon

Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
