Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding01:15

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

1.3K
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Gastrointestinal Motility Disorders01:20

Gastrointestinal Motility Disorders

1.4K
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...

Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists

1.5K
Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...

Gastritis III: Clinical Manifestations and Management

1.5K
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Area of Science:

  • Gastroenterology
  • Neurogastroenterology
  • Digestive Physiology

Background:

  • Gastroparesis (Gp) is characterized by symptoms like nausea, vomiting, and delayed gastric emptying.
  • Diagnosis requires symptoms and objective evidence of delayed emptying without obstruction.
  • Current understanding of Gp pathogenesis involves intricate interactions within the nervous system.

Purpose of the Study:

  • To review recent advancements in the pathogenesis of gastroparesis.
  • To discuss updated management strategies for gastroparesis.
  • To introduce gastroparesis-like syndrome (GLS) and its relationship to Gp.

Main Methods:

  • Review of recent scientific literature on gastroparesis pathogenesis and management.
  • Analysis of studies involving full thickness biopsies in Gp patients.
  • Examination of the role of gastric electrical stimulators (GES) in treatment.

Main Results:

  • Full thickness biopsies reveal complex central, autonomic, and enteric nervous system interactions in Gp.
  • Gastric electrical stimulators (GES) represent an evolving management option beyond traditional prokinetics and antiemetics.
  • Gastroparesis-like syndrome (GLS) shares similar pathophysiology with Gp and shows significant benefit from GES.

Conclusions:

  • Nervous system dysregulation is central to gastroparesis pathogenesis.
  • Gastric electrical stimulation is a promising therapeutic approach for both Gp and GLS.
  • GLS patients may be effectively managed similarly to Gp patients, particularly with GES.
