Core Tip

Core tip: Laparoscopic Heller myotomy (LHM) is commonly used to treat achalasia and an antireflux procedure is added after LHM for prevention of gastroesophageal reflux (GER). However, there is no consensus on whether Dor fundoplication is the optimum procedure after LHM for the prevention of GER. We conducted this meta-analysis to assess Dor fundoplication compared with non-fundoplication surgery or other types of fundoplication surgery for achalasia. The results indicated higher recurrence rate of clinical regurgitation and pathological acid reflux in Dor fundoplication indicating that Dor fundoplication is not the optimum procedure for the prevention of GER after LHM in achalasia patients.
