Summary
A Colombian woman experienced chronic diarrhea for four years. Colonoscopy revealed whipworm infection (Trichuris trichiura) as the cause of her persistent gastrointestinal symptoms.
Area of Science:
- Medicine
- Infectious Diseases
- Gastroenterology
Background:
- Chronic diarrhea can significantly impact quality of life.
- Identifying the underlying cause of persistent gastrointestinal symptoms is crucial for effective treatment.
Purpose of the Study:
- To investigate the etiology of chronic diarrhea in a 62-year-old woman presenting with lienteric stools.
Main Methods:
- Clinical evaluation including patient history and physical examination.
- Diagnostic procedures included stool analysis and colonoscopy.
Main Results:
- Initial stool tests were inconclusive for parasites.
- Colonoscopy identified numerous mobile, white worms in the right colon, consistent with Trichuris trichiura.
- The patient was diagnosed with trichuriasis.
Conclusions:
- Trichuris trichiura infection can present as chronic diarrhea.
- Colonoscopy is a valuable tool for diagnosing intestinal helminth infections when stool tests are negative.

01:17Chronic Bowel Disorders: Introduction
385
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

01:25Assessment of the Rectum and Anus
137
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.

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:

01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

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...
