Insights
Heller's myotomy for achalasia can be performed without fundoplication, with excellent functional results and low reflux rates. This approach avoids unnecessary surgery for patients with lower oesophageal sphincter achalasia.
Area of Science:
- Gastroenterology
- Surgical Innovation
- Esophageal Motility Disorders
Background:
- Achalasia treatment often involves Heller's myotomy with fundoplication to prevent reflux.
- The necessity and efficacy of routine fundoplication are debated.
- This study evaluates Heller's myotomy without fundoplication using a specific technique to mitigate reflux.
Observation:
- 123 patients underwent Heller's myotomy without routine fundoplication between 1975 and 1999.
- The abdominal approach was used in 95% of cases, preserving esophageal fixation.
- A precise surgical technique was employed to prevent postoperative gastro-oesophageal reflux.
Findings:
- Low mortality (0.8%) and morbidity (1.6%) were observed.
- Satisfactory functional outcomes (92% excellent/good) were achieved at a mean 5-year follow-up.
- A low rate of postoperative reflux (6%) occurred, with only one requiring reoperation.
Implications:
- Systematic fundoplication may not be essential for Heller's myotomy in achalasia.
- A meticulous surgical technique can achieve good outcomes without routine fundoplication.
- This approach offers a potentially less invasive option for achalasia treatment.
Introduction:
Surgical treatment of achalasia of lower oesophageal sphincter is Heller's myotomy, usually associated with a fundoplication due to an high risk of postoperative gastro-oesophageal reflux. The value of this fundoplication is discussed. The aim of this study was to evaluate retrospectively the results of Heller's myotomy without fundoplication but performed according to a precise technique preventing postoperative reflux.
Patients And Methods:
Between 1975 and 1999, 123 patients underwent Heller's myotomy without systematic fundoplication. Diagnosis of achalasia was performed clinically and confirmed by investigations: baryum meal, fibroscopy and manometry. Myotomy was performed through an abdominal approach in 117 (95%) patients. Dissection preserved fixity of abdominal oesophagus in all cases, particularly its posterior meso. Myotomy was performed on abdominal oesophagus but not below the cardia. Posterior fundoplication was associated in 2 patients.
Results:
One patient (0,8%) died from massive aspiration. Morbidity (1,6%) consisted in one peritonitis and one postoperative occlusion. At follow-up (mean = 5 years; range: 1-20), functional results were satisfying (excellent and good) in 112 (92%) patients. Seven patients (6%) developed postoperative reflux, including one who need surgical treatment. Dysphagia persisted in 3 patients (2%) who had to be reoperated.
Conclusion:
Results of this series show that systematic fundoplication is not necessary in Heller's myotomy for achalasia of lower oesophageal sphincter.
