Insights

Internal hernias are rare, with Meckel diverticulum being a common congenital anomaly. This case highlights multidetector computed tomography (MDCT) and multiplanar reconstruction for diagnosing a large Meckel diverticulum within a right paracolic hernia.

Area of Science:

  • Gastroenterology
  • Radiology
  • Surgical Pathology

Background:

  • Internal hernias are uncommon, with autopsy rates between 0.2% and 0.9%.
  • Meckel diverticulum, the most frequent congenital gastrointestinal anomaly, affects 1-3% of the population.
  • Diagnosis of these conditions often occurs during surgery or due to complications identified via imaging.

Observation:

  • A rare case of a large Meckel diverticulum incarcerated within a right paracolic hernia is presented.
  • The patient experienced episodes of subacute intestinal obstruction.
  • Diagnosis was achieved using multidetector computed tomography (MDCT).

Findings:

  • MDCT with multiplanar reconstruction (MPR) proved effective in diagnosing the complex hernia and its contents.
  • The imaging findings correlated with the clinical presentation of intermittent bowel obstruction.
  • This case underscores the diagnostic utility of advanced CT techniques.

Implications:

  • Multidetector computed tomography and MPR are crucial for diagnosing challenging internal hernia cases.
  • Early and accurate diagnosis can prevent complications associated with incarcerated Meckel diverticulum.
  • This case contributes to the understanding of rare gastrointestinal pathologies and their imaging features.

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...
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...

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies

Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
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.

Begin by inspecting the perianal and anal areas for color, texture, rashes,...
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:
