Gastric Motility01:16

Gastric Motility

2.9K
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.

Gastric Emptying01:16

Gastric Emptying

3.4K
Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...

Gastric Phase of Digestion01:26

Gastric Phase of Digestion

3.1K
The gastric phase of digestion begins as soon as food enters the stomach. The incoming food bolus triggers neural and hormonal mechanisms, which last approximately 3 to 4 hours. During this phase, the stomach undergoes significant changes to prepare the food for further digestion and absorption.
When food enters the stomach, it stretches the stomach walls and activates stretch receptors. This triggers local reflexes of the enteric nervous system, mediated through the myenteric plexus. These...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

860
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis II

1.4K
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Pulmonary Tuberculosis V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

  • Gastroenterology
  • Infectious Diseases
  • Oncology

Background:

  • Tuberculosis (TB) is a rare cause of gastric disease, often presenting symptoms similar to gastric carcinoma.

  • Diagnosis is frequently delayed until surgical intervention is required.

Observation:

  • The authors present 4 cases of gastric tuberculosis over a 5-year period.
  • Gastric tuberculosis mimics gastric carcinoma, complicating early diagnosis.
  • Endoscopy with guided biopsy is the primary diagnostic tool.

Findings:

  • Patients with gastric tuberculosis respond well to antituberculous therapy.
  • Surgery is reserved for complicated cases of gastric tuberculosis.
  • This study provides a comprehensive literature review and updates on gastric tuberculosis.

Implications:

  • Highlights the importance of considering gastric tuberculosis in differential diagnosis of gastric lesions.
  • Emphasizes the role of endoscopic biopsy in achieving timely diagnosis.
  • Underscores the efficacy of antituberculous therapy in managing gastric tuberculosis.
