2011 update on esophageal achalasia

Area of Science:

• Gastroenterology
• Digestive Endoscopy
• Surgical Innovation

Background:

• Esophageal achalasia diagnosis and treatment have seen recent advancements.
• High-resolution manometry with pressure topography plotting aids in achalasia classification.
• Understanding achalasia subtypes is crucial for predicting treatment outcomes.

Purpose of the Study:

• To review recent breakthroughs in esophageal achalasia diagnosis and treatment.
• To compare the efficacy of different treatment modalities for achalasia.
• To highlight emerging endoscopic techniques for achalasia management.

Main Methods:

• Classification of achalasia into three subtypes using high-resolution manometry.
• Analysis of a multicenter randomized controlled trial comparing laparoscopic Heller myotomy and pneumatic dilation (PD).
• Evaluation of peroral endoscopic myotomy as a novel treatment option.

Main Results:

• High-resolution manometry identified three achalasia subtypes with varying prognoses.
• Laparoscopic Heller myotomy showed no superiority over pneumatic dilation (PD) in a 2-year follow-up.
• Peroral endoscopic myotomy is a promising but less established technique requiring further study.

Conclusions:

• Esophageal achalasia diagnosis is enhanced by new manometry techniques.
• Pneumatic dilation remains a viable and accessible treatment option.
• Further research is needed to identify the underlying causes of achalasia for improved treatment success.
