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...

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...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

663
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Intestinal Obstruction I: Introduction01:29

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,...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.2K
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...

Endoscopic Procedures II: Colonoscopy

1.3K
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Summary

Transverse colon volvulus, a rare cause of bowel obstruction, is challenging to diagnose. Resection is the preferred treatment to prevent recurrence, unlike less effective detorsion methods.

Area of Science:

  • Gastroenterology
  • Abdominal Surgery
  • Diagnostic Imaging

Background:

  • Colonic obstruction is frequently caused by sigmoid or cecal volvulus.
  • Transverse colon volvulus is a rare condition, often presenting diagnostic challenges.

Observation:

  • Multidetector computed tomography (MDCT) aids in diagnosing transverse colon volvulus.
  • MDCT reveals dilated proximal colon loops and a mesentery torsion at the splenic flexure.

Findings:

  • Surgical resection with or without anastomosis is the definitive treatment for transverse colon volvulus.
  • Detorsion techniques, with or without colopexy, have high recurrence rates compared to resection.

Implications:

  • Transverse colon volvulus requires consideration in differential diagnoses for abdominal pain and obstruction.
  • Early surgical intervention, particularly resection, is crucial to prevent complications like gangrene and perforation.
