Gastric Motility01:16

Gastric Motility

Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.

Gastritis II: Pathophysiology01:26

Gastritis II: Pathophysiology

The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
Pyloric Obstruction01:11

Pyloric Obstruction

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...
Gastrointestinal Motility Disorders01:20

Gastrointestinal Motility Disorders

Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...
Barrett Esophagus-I: Introduction01:21

Barrett Esophagus-I: Introduction

Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...
Esophageal Strictures-II: Clinical Features and Management01:26

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Summary

Trichobezoar, a rare condition often linked to psychiatric illness, presents diagnostic challenges, particularly in young females. Early recognition is crucial to prevent severe complications.

Area of Science:

  • Gastroenterology
  • Psychiatry
  • Radiology

Background:

  • Trichobezoar is a rare gastrointestinal condition characterized by the accumulation of ingested hair.
  • It often presents diagnostic challenges due to vague symptoms and potential patient reluctance to disclose history, frequently associated with underlying psychiatric disorders.

Purpose of the Study:

  • To highlight the diagnostic difficulties associated with trichobezoar.
  • To emphasize the importance of considering trichobezoar in the differential diagnosis, especially in specific patient demographics.
  • To present a classic case illustrating typical patient profile, clinical presentation, and diagnostic findings.

Main Methods:

  • Case report detailing a patient with trichobezoar.
  • Review of patient's clinical presentation, medical history, and psychiatric comorbidities.
  • Analysis of diagnostic investigations, including imaging and endoscopic findings.

Main Results:

  • The case presented a classic profile of trichobezoar.
  • Diagnostic delays were noted, underscoring the challenges in identification.
  • Investigative findings were consistent with established literature on trichobezoar.

Conclusions:

  • Trichobezoar requires a high index of suspicion, particularly in young females with psychiatric comorbidities.
  • Timely diagnosis and intervention are essential to avoid potentially fatal complications.
  • This case underscores the need for thorough evaluation in patients with unexplained gastrointestinal symptoms.
