Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

47
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...

Intestinal Obstruction I: Introduction

51
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,...

Pyloric Obstruction01:11

Pyloric Obstruction

40
Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...

Hiatal Hernia01:25

Hiatal Hernia

86
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...

Diverticular Disease of the Colon01:27

Diverticular Disease of the Colon

44
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

29
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...

Summary

A Bochdalek hernia in an adult patient caused intestinal obstruction. Early surgical intervention is crucial for Bochdalek hernia cases, especially with incarceration or perforation, to prevent severe complications.

Area of Science:

  • Gastroenterology
  • Thoracic Surgery
  • Medical Imaging

Background:

  • Adult Bochdalek hernias are rare congenital abnormalities.
  • They can present with non-specific symptoms, leading to delayed diagnosis.

Observation:

  • A 78-year-old male presented with abdominal pain and vomiting, diagnosed with intestinal obstruction.
  • Imaging revealed intestinal gas in the thorax and suspected diaphragmatic hernia.

Findings:

  • Surgery confirmed a left Bochdalek hernia containing a perforated small intestine.
  • The patient recovered well after surgical repair and was discharged on postoperative day 35.

Implications:

  • This case highlights the importance of considering Bochdalek hernia in adults with intestinal obstruction.
  • Prompt surgical treatment is vital to avoid complications like incarceration and perforation, improving patient outcomes.
