[Laparoscopic cardiomyotomy in achalasia]

Area of Science:

• Gastroenterology
• Minimally Invasive Surgery
• Esophageal Motility Disorders

Background:

• Achalasia, a rare esophageal motility disorder, is typically treated with cardiomyotomy or endoscopic pneumatic dilatation.
• Laparoscopic cardiomyotomy presents a minimally invasive alternative to conventional surgery, potentially improving postoperative recovery.

Purpose of the Study:

• To evaluate the safety and efficacy of laparoscopic cardiomyotomy for achalasia.
• To assess the postoperative convalescence and functional outcomes of patients undergoing this minimally invasive procedure.

Main Methods:

• Four patients with achalasia underwent laparoscopic cardiomyotomy between May 1994 and October 1995.
• All patients had prior endoscopic therapy, and the myotomy was extended only shortly onto the stomach without an antireflux procedure.
• Intraoperative endoscopic control confirmed myotomy extension and mucosal integrity.

Main Results:

• All patients could swallow immediately post-operation and were discharged between 2 and 8 days postoperatively.
• Follow-up up to 18 months showed complete resolution of dysphagia and regurgitation in all patients.
• One patient reported mild reflux symptoms; dynamic esophageal X-rays confirmed free passage to the stomach.

Conclusions:

• Laparoscopic cardiomyotomy is a feasible and effective surgical treatment for achalasia, offering significant advantages in postoperative recovery.
• The procedure yields good functional results, with minimal invasiveness leading to rapid patient improvement.
• The necessity of an antireflux procedure may be debated, potentially being unnecessary with limited myotomy extension onto the stomach.
