Chagas' achalasia treated by a jejunal interposed segment

Area of Science:

• Gastroenterology
• Surgical Innovation
• Chagas Disease Management

Background:

• Achalasia, a motility disorder, causes esophageal dilation and dysphagia.
• Severe achalasia, especially in Chagas' disease, presents significant treatment challenges.
• Current surgical options for advanced achalasia have varying success rates.

Purpose of the Study:

• To assess the efficacy of a specific surgical intervention for achalasia.
• To evaluate outcomes in patients with significantly dilated esophagi, including those with Chagas' disease.
• To determine the safety and effectiveness of jejunal loop interposition combined with vagotomy and pyloroplasty.

Main Methods:

• Surgical resection of the achalasic segment of the esophagus.
• Esophageal reconstruction using a segment of jejunal loop.
• Concomitant performance of vagotomy and pyloroplasty.
• Study included 21 patients, predominantly with Chagas' disease and marked esophageal dilation (>7 cm).

Main Results:

• The surgical procedure resulted in symptomatic relief in 20 out of 21 patients (95.2% success rate).
• Significant reduction in dysphagia and regurgitation severity was observed.
• One patient experienced a non-operation-related mortality.
• The majority of patients were able to lead normal lives post-surgery despite residual mild symptoms.

Conclusions:

• Jejunal loop interposition with vagotomy and pyloroplasty is a highly effective treatment for severe achalasia.
• This surgical approach offers substantial symptomatic improvement and enhanced quality of life for patients, including those with Chagas' disease.
• The procedure demonstrates a favorable safety profile with minimal mortality.
