Q

Achalasia management Pharmacological

A

Nitrates, Ca channel blockers, PDE-5i to reduce sphincter pressure. These treatments have side effects (hypotension, pedal oedema, headache, rapid tolerance) that limit them to use for patients who decline or are waiting for more defintive action (pneumatic dilatation or surgery)

Q

Achalasia Mx non surgical

A
  • Endoscopic injection of botulinum toxin: Used in poor candidates for surgery or those who relapse after myotomy, or as bridge therapy. Lasts only 6-12m, is expensive and may reduce success rate of myotomy
    Pneumatic dilatation: Improvement in 50-90% of patients but 30% recurr in 5y. Symptom relief similar to myotomy if available on demand.

Q

Achalasia Mx surgical

A

Laparoscopic Heller myotomy with partial fundoplication (which is an anti-reflux procedure) is first choice as the myotomy can cause unopposed reflux. Insicion into fibres of LOS leading to relaxation. Success 76-100%

Q

Complications of achalasia

A
  1. Perforation- Consider Mx with NBM, broad spec Abx and PPI with nutritional support. But may require surgical intervention to close perforation
    1. Recurrence - step up treatment ladder if not already done
    2. GORD - PPI, use of fundoplication with surgical approach
    3. Bloating
      Cancer risk increased (oesophageal)
