| Summary: | Summary: Laparoscopic Heller Myotomy (LHM) with partial fundoplication has become the treatment of choice for esophageal achalasia. However, the choice of the partial fundoplication is debated. The aim of this study was to compare outcomes for Dor and Toupet fundoplication after LHM. A systematic search of randomized controlled trials comparing Dor and Toupet fundoplication was performed using PubMed, EMBASE and Web of Science. Three studies met the inclusion criteria. Overall, 174 patients were included in the analysis. The postoperative abnormal acid reflux [pooled Risk Ratio 0.98 (95% HPD 0.54–1.80)] and dysphagia [pooled Risk Ratio 1.03 (95% HPD 0.51–2.05)] were similar comparing Dor and Toupet fundoplication. The % total time pH ≤ 4 [estimated pooled mean difference −0.08 (95% HPD −1.04–0.90)] and DeMeester score [estimated pooled mean difference 0.51 (95% HPD −0.90–1.94)] were comparable. Additionally, the operative time [estimated pooled mean difference 0.02 (95% HPD −0.53–0.52)] and iatrogenic esophageal perforation [pooled Risk Ratio 1.05 (95% HPD 0.52–2.10)] were similar in the two groups. Dor and Toupet fundoplication after laparoscopic Heller myotomy seem comparable in term of postoperative abnormal acid exposure and dysphagia. The choice of the partial fundoplication should be left to surgeon experience and tailored on each patient.
