Summary
Achalasia, a swallowing disorder, involves esophageal muscle dysfunction and lower esophageal sphincter issues. Surgical esophagomyotomy effectively relieves symptoms in over 90% of patients with this condition.
Area of Science:
- Gastroenterology
- Esophageal Motility Disorders
Background:
- Achalasia is defined by absent esophageal peristalsis and impaired lower esophageal sphincter relaxation.
- This condition leads to dysphagia (difficulty swallowing) for both solids and liquids.
Purpose of the Study:
- To summarize the diagnostic methods and primary treatment for achalasia.
- To highlight the efficacy of surgical esophagomyotomy in managing achalasia symptoms.
Main Methods:
- Diagnosis is confirmed using barium swallow, esophageal manometry, and flexible endoscopy.
- Treatment focuses on disrupting the lower esophageal sphincter.
Main Results:
- Surgical esophagomyotomy is a primary treatment modality.
- Esophagomyotomy achieves symptom relief in over 90% of achalasia patients.
Conclusions:
- Achalasia diagnosis relies on a combination of imaging and manometry.
- Surgical esophagomyotomy offers highly effective symptom relief for achalasia.

01:21Barrett Esophagus-II: Clinical Manifestations and Management
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...

01:26Esophageal Strictures-II: Clinical Features and Management
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.

01:27Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
