Hiatal Hernia

Hiatal Hernia

A hiatal hernia is the abnormal protrusion of the stomach or other abdominal organs through the esophageal hiatus of the diaphragm into the thoracic cavity.Normally, the gastroesophageal junction (GEJ) lies below the diaphragm and is supported by the phrenoesophageal membrane, the diaphragmatic crura, and connective tissues. Weakening of these structures—due to aging, congenital defects like a short esophagus, or increased intra-abdominal pressure from coughing, obesity, pregnancy, or heavy...

Intestinal Obstruction I: Introduction

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,...

Appendicitis

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...

Diverticular Disease of the Colon

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 Anus

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,...

Summary

Internal hernias, a rare cause of small bowel obstruction, can occur without prior surgery. This report details two young patients experiencing mesocolic hernias presenting as obstruction, challenging typical etiological assumptions.

Area of Science:

Gastroenterology
Surgical Pathology

Background:

Internal hernias are uncommon, with an incidence of 1-2%, often congenital or acquired.
They are a rare cause of small bowel obstruction (0.2-0.9%), with paraduodenal hernias being most frequent.
Mesocolic hernias are less common and typically associated with prior abdominal surgery.

Purpose of the Study:

To report unusual cases of mesocolic hernias.
To highlight the presentation of small bowel obstruction in young patients without a surgical history.

Main Methods:

Case report of two young patients.
Clinical and radiological evaluation for small bowel obstruction.

Main Results:

Two young patients presented with small bowel obstruction.
No prior abdominal surgery was identified in either patient.
Mesocolic hernias were diagnosed as the cause of obstruction.

Conclusions:

Mesocolic hernias can occur in young individuals without a history of abdominal surgery.
This presentation underscores the importance of considering internal hernias in the differential diagnosis of small bowel obstruction, even in atypical patient profiles.
