Abstract
BACKGROUND: Since its first description in the early 1990s, minimally invasive Heller myotomy has become the treatment of choice for esophageal achalasia. We report the experience of a single unit with thoracoscopic Heller myotomy (THM) and laparoscopic Heller myotomy (LHM) and we analyze the short- and long-term surgical outcomes in patients treated by each of the two approaches. METHODS: We evaluated retrospectively 33 patients who underwent surgical treatment for achalasia. Sixteen patients underwent THM without an antireflux procedure, and 17 patients underwent LHM and partial anterior fundoplication (n = 10) or closure of the angle of His (n = 7). RESULTS: Mean operative time was significantly shorter for LHM than for THM (150 vs 222 min, respectively) (p = 0.0001). Mean hospital stay was significantly shorter after LHM than after THM (2.0 ± 1.0 vs 5.1 ± 2.2 days, respectively) (p = 0.0001). Six of 16 patients (37.5%) in the THM group experienced persistent or recurrent dysphagia compared to one of 17 patients (5.8%) in the LHM group (p = 0.04). Heartburn developed in five patients (31.2%) after THM and in one patient (5.8%) after LHM (p = 0.07). Regurgitation developed in four patients (25%) after THM and in one patient (5.8%) after LHM (p = 0.149). Lower esophageal sphincter (LES) basal pressure decreased significantly from 30.1 ± 5.07 to 15.3 ± 2.1 after THM and from 32.1 ± 5.9 to 10.5 ± 1.7 after LHM (p = 0.0001). Mean esophageal diameter was significantly reduced after LHM compared to THM (from 54.5 ± 5.7 mm to 27.1 ± 3.3 mm vs 50.8 ± 7.6 mm to 37.2 ± 6.9 mm, respectively) (p = 0.0001). CONCLUSION: In our experience, LHM is associated with a shorter operative time and a shorter hospital stay, and it is superior to THM in relieving dysphagia. LHM with partial anterior fundoplication should be considered the treatment of choice for achalasia.
