    Study Notes

    Esophageal Motility Disorders Overview

    • Esophageal motility disorders affect the ability of the esophagus to peristaltically move food and liquids into the stomach.
    • Two main dysfunctions are involved: nerve disorders and muscle disorders of the esophagus.
    • Common symptom associated with these disorders is dysphagia (difficulty swallowing), which can affect solids and liquids.

    Nerve and Muscle Dysfunction

    • Dysfunction of innervating nerves can lead to decreased nitric oxide and vasoactive intestinal peptide, resulting in increased tone of the lower esophageal sphincter (LES) and impaired relaxation.
    • High muscle tone in the LES can lead to obstructive symptoms, while muscle dysfunction can affect motility throughout the esophagus.

    Complications

    • Increased risk of esophageal cancer, particularly with conditions like achalasia and esophageal scleroderma.
    • Aspiration risk rises due to impaired clearance of food or fluids, leading to potential respiratory issues.

    Specific Disorders

    • Achalasia:

      • Characterized by damage to the myenteric plexus, leading to decreased nitric oxide and vasoactive peptides.
      • Results in high tone of the LES and decreased motility in the mid-distal esophagus.
      • Secondary causes can include Chagas disease (Trypanosoma cruzi), which causes a classic triad of megaesophagus, megacolon, and dilated cardiomyopathy.

    • Diffuse Esophageal Spasm:

      • High amplitude contractions occur in a disorganized manner.
      • Lower esophageal sphincter tone remains normal but there's significant hypermotility in the mid-distal esophagus, causing dysphagia and chest pain.

    • Esophageal Scleroderma:

      • Characterized by atrophy and fibrosis of the esophageal tissue, including the LES.
      • Lower esophageal sphincter tone and overall motility decrease due to connective tissue changes.
      • Associated with limited cutaneous scleroderma (CREST syndrome): Calcinosis, Raynaud's phenomenon, Esophageal dysmotility, Sclerodactyly, and Telangiectasia.

    Diagnostics

    • Barium Swallow:

      • Useful initial test; may show "bird's beak" for achalasia and "corkscrew" appearance for diffuse esophageal spasm.

    • Esophagogastroduodenoscopy (EGD):

      • Can rule out malignancy and assess for atrophy or fibrosis.

    • Esophageal Manometry:

      • Gold standard for assessment:
        • Achalasia: low motility in the mid-distal esophagus and high LES pressure.
        • Diffuse esophageal spasm: high amplitude contractions in the mid-distal esophagus with normal LES tone.
        • Scleroderma: decreased mid-distal motility and low LES pressure.

    Treatment Approaches

    • Achalasia:

      • Medical therapies like calcium channel blockers and nitrates may provide relief, but surgical options are often needed (pneumatic dilation, Heller myotomy, botulinum toxin injections).

    • Diffuse Esophageal Spasm:

      • First-line treatment includes calcium channel blockers or nitrates; surgical options are less common.

    • Scleroderma:

      • Focus on managing reflux esophagitis with proton pump inhibitors (PPIs).
      • No specific surgical therapies are indicated.

    Key Takeaways

    • Achalasia has a preference for surgical therapy due to poor response to medical treatments.
    • For diffuse esophageal spasm, medical management is preferred over surgical interventions.
    • Scleroderma requires careful monitoring for reflux complications, with medical management as the primary treatment modality.

    • Affect the esophagus's ability to move food and liquids into the stomach.
    • Two primary dysfunctions: nerve disorders and muscle disorders.
    • Dysphagia is a common symptom, impacting both solids and liquids.

    Nerve and Muscle Dysfunction

    • Dysfunction in innervating nerves decreases production of nitric oxide and vasoactive intestinal peptide.
    • Results in increased tone of the lower esophageal sphincter (LES) and impaired relaxation.
    • High LES tone causes obstructive symptoms; muscle dysfunction impacts overall motility.

    Complications

    • Higher risk of esophageal cancer, notably with achalasia and esophageal scleroderma.
    • Increased aspiration risk due to impaired clearance of food or fluids, leading to respiratory complications.

    Specific Disorders

    • Achalasia:

      • Damage to the myenteric plexus decreases nitric oxide and vasoactive peptides.
      • High LES tone and impaired mid-distal esophageal motility.
      • Secondary causes include Chagas disease, leading to megaesophagus, megacolon, and dilated cardiomyopathy.

    • Diffuse Esophageal Spasm:

      • Characterized by high amplitude contractions that are disorganized.
      • Normal LES tone, but hypermotility in mid-distal esophagus causes dysphagia and chest pain.

    • Esophageal Scleroderma:

      • Involves atrophy and fibrosis of the esophageal tissue and LES.
      • Decreased LES tone and overall motility due to connective tissue changes.
      • Associated with CREST syndrome: Calcinosis, Raynaud's phenomenon, Esophageal dysmotility, Sclerodactyly, Telangiectasia.

    Diagnostics

    • Barium Swallow:

      • Initial test showing "bird's beak" for achalasia and "corkscrew" for diffuse esophageal spasm.

    • Esophagogastroduodenoscopy (EGD):

      • Helps rule out malignancy and assess tissue for atrophy or fibrosis.

    • Esophageal Manometry:

      • Gold standard for assessment:
        • Achalasia: low mid-distal esophageal motility, high LES pressure.
        • Diffuse esophageal spasm: high amplitude contractions, normal LES tone.
        • Scleroderma: decreased mid-distal motility, low LES pressure.

      • Normal LES tone, but hypermotility in mid-distal esophagus causes dysphagia and chest pain.

    • Esophageal Scleroderma:

      • Involves atrophy and fibrosis of the esophageal tissue and LES.
      • Decreased LES tone and overall motility due to connective tissue changes.
      • Associated with CREST syndrome: Calcinosis, Raynaud's phenomenon, Esophageal dysmotility, Sclerodactyly, Telangiectasia.

    Diagnostics

    • Barium Swallow:

      • Initial test showing "bird's beak" for achalasia and "corkscrew" for diffuse esophageal spasm.

    • Esophagogastroduodenoscopy (EGD):

      • Helps rule out malignancy and assess tissue for atrophy or fibrosis.

    • Esophageal Manometry:

      • Gold standard for assessment:
        • Achalasia: low mid-distal esophageal motility, high LES pressure.
        • Diffuse esophageal spasm: high amplitude contractions, normal LES tone.
        • Scleroderma: decreased mid-distal motility, low LES pressure.

    Treatment Approaches

    • Achalasia:

      • Medical treatments like calcium channel blockers and nitrates offer some relief.
      • Surgical options often necessary: pneumatic dilation, Heller myotomy, or botulinum toxin injections.

    • Diffuse Esophageal Spasm:

      • First-line treatment includes calcium channel blockers or nitrates; surgery is less common.

    • Scleroderma:

      • Management focuses on reflux esophagitis with proton pump inhibitors (PPIs).
      • No specific surgical therapies available.

    Key Takeaways

    • Surgical therapy preferred for achalasia due to poor response to medical treatments.
    • Diffuse esophageal spasm typically managed with medical interventions rather than surgery.
    • Scleroderma requires careful monitoring and medical management as the primary approach for reflux complications.

    Esophageal Motility Disorders Overview

    • Affect the esophagus's ability to move food and liquids into the stomach.
    • Two primary dysfunctions: nerve disorders and muscle disorders.
    • Dysphagia is a common symptom, impacting both solids and liquids.

    Nerve and Muscle Dysfunction

    • Dysfunction in innervating nerves decreases production of nitric oxide and vasoactive intestinal peptide.
    • Results in increased tone of the lower esophageal sphincter (LES) and impaired relaxation.
    • High LES tone causes obstructive symptoms; muscle dysfunction impacts overall motility.

    Complications

    • Higher risk of esophageal cancer, notably with achalasia and esophageal scleroderma.
    • Increased aspiration risk due to impaired clearance of food or fluids, leading to respiratory complications.

    Specific Disorders

    • Achalasia:

      • Damage to the myenteric plexus decreases nitric oxide and vasoactive peptides.
      • High LES tone and impaired mid-distal esophageal motility.
      • Secondary causes include Chagas disease, leading to megaesophagus, megacolon, and dilated cardiomyopathy.

    • Diffuse Esophageal Spasm:

      • Characterized by high amplitude contractions that are disorganized.
      • Normal LES tone, but hypermotility in mid-distal esophagus causes dysphagia and chest pain.

    • Esophageal Scleroderma:

      • Involves atrophy and fibrosis of the esophageal tissue and LES.
      • Decreased LES tone and overall motility due to connective tissue changes.
      • Associated with CREST syndrome: Calcinosis, Raynaud's phenomenon, Esophageal dysmotility, Sclerodactyly, Telangiectasia.
