Insights

Adult intussusception is rare, often presenting with non-specific symptoms. This case highlights a large submucosal lipoma causing ileocecal intussusception in a 36-year-old man, successfully treated with surgery.

Area of Science:

  • Gastroenterology
  • Surgical Pathology

Background:

  • Intussusception is uncommon in adults, often presenting with vague abdominal symptoms.
  • Adult intussusception can be caused by various underlying pathologies, including benign tumors.

Purpose of the Study:

  • To report a rare case of adult intussusception secondary to a submucosal lipoma.
  • To review the diagnostic and therapeutic challenges of intussusception in adults.

Main Methods:

  • Case report of a 36-year-old male with abdominal pain and rectal prolapse.
  • Diagnostic workup included physical examination, plain film, barium enema, colonoscopy, and laparotomy.
  • Surgical resection of the ileocecal mass.

Main Results:

  • A large (15 cm x 12 cm) intra-abdominal mass was identified during laparotomy, connecting the ileum and sigmoid colon.
  • Pathology revealed a 9 cm x 6 cm x 5 cm submucosal lipoma at the ileocecal junction.
  • The patient experienced an uneventful post-operative recovery.

Conclusions:

  • Submucosal lipomas can lead to adult intussusception.
  • Prompt surgical intervention is crucial for managing adult intussusception.
  • Adult intussusception requires a high index of suspicion and thorough investigation.

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,...

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...
Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
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...
Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...
