Insights

Heller myotomy (HM) with fundoplication (HMF) shows no significant difference in achalasia outcomes compared to HM alone. This meta-analysis found similar rates of gastroesophageal reflux and dysphagia between the two surgical approaches.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Digestive System Diseases

Background:

  • Heller myotomy (HM) is the standard surgical treatment for achalasia.
  • The addition of fundoplication to HM (HMF) is debated due to conflicting study results.
  • This meta-analysis aims to clarify outcomes of HM versus HMF.

Purpose of the Study:

  • To compare the long-term outcomes of Heller myotomy (HM) versus HM with fundoplication (HMF) for achalasia.
  • To evaluate differences in gastroesophageal reflux and dysphagia rates between HM and HMF.

Main Methods:

  • Systematic electronic search of five databases (PubMed, Ovid, Scopus, Cochrane Library, Google Scholar) up to October 2019.
  • Inclusion of randomized and non-randomized studies comparing HM and HMF.
  • Random-effects meta-analysis of primary (gastroesophageal reflux) and secondary (dysphagia) outcomes.

Main Results:

  • Six studies involving 576 patients were analyzed.
  • No statistically significant difference in gastroesophageal reflux between HM and HMF groups (21.3% vs. 22.9%, p=0.49).
  • A trend towards higher dysphagia incidence in the HM group compared to HMF (14.8% vs. 10.8%, p=0.06).

Conclusions:

  • Heller myotomy with fundoplication does not offer statistically significant long-term outcome advantages over Heller myotomy alone for achalasia.
  • Both procedures demonstrate comparable efficacy in managing achalasia symptoms.
  • Further research may be warranted to explore subtle differences in specific patient subgroups.
