Medium and long-term outcomes after pneumatic dilation or laparoscopic Heller myotomy for achalasia: a meta-analysis

Abstract

Recent randomized studies comparing outcomes after pneumatic dilation (PD) and laparoscopic Heller myotomy (LHM) for the treatment of achalasia are conflicting and limited to short-term follow-up. Our meta-analysis compared the long-term durability of these approaches, with the hypothesis that LHM offers superior long-term remission compared with PD. We identified 36 studies published between 2001 and 2011 with at least 5 years of follow-up. Those studies describing PD included 3211 patients (mean age, 49.8 y). For PD, the mean 5-year remission rate was 61.9% and the mean 10-year remission rate was 47.9%. Overall, 1526 patients (mean age, 46.3 y) were treated with LHM; 83% received a fundoplication. In contrast, the mean 5- and 10-year remission rates after LHM were 76.1% and 79.6%, respectively. Finally, the perforation rate for LHM was twice that of PD (4.8% vs. 2.4%; P<0.05). We conclude that despite a higher frequency of perforation, LHM affords greater long-term durability.
