Background: In spite of the introduction of peroral endoscopic myotomy (POEM), Heller myotomy (HM) remains the mainstay of treatment and the role of pneumatic dilatation (PD) is being debated. The aim of this study was to present a single-center experience in the diagnostic approach and treatment of esophageal achalasia (EA), including the long-term assessment of the QoL. Methods: Data collection was based on the retrospective analysis of clinical notes and prospective interviews with patients and their parents. Results: The study group consisted of 60 patients with EA (F: 26, M: 34), with a median age of 12.0 (1–17) years at diagnosis. The time from the first symptoms until the diagnosis was 1.0 year (0.5–2.0) and the most common were: regurgitation (91.3%), dysphagia (84.8%), and chest pain (47.8%). The diagnostic approach showed a high sensitivity for barium X-ray follow through, esophageal manometry, and endoscopy. Overall, a long-term good outcome of HM was achieved in 27 out of 37 patients (73%) and it was negatively affected by the time between the first symptoms and the diagnosis. Out of the 16 patients who underwent PD before HM, a good outcome was achieved in 14 patients (87.5%), compared to 13 out of 21 patients (62%) who only underwent HM (p = 0.22). Concomitant fundoplication was routinely performed, and 18% required post-operative endoscopic dilatation. At the end of the 12.1 (0.7–26.6)-year follow up, most patients had a good QoL, which significantly corresponded with the treatment outcomes. Conclusions: Patients suspected of EA should undergo a thorough clinical evaluation including a manometry, a barium X-ray, and an endoscopy. HM is a safe and effective treatment for achalasia and the outcome is not worsened by a preceding endoscopic PD. In most patients, HM alleviates symptoms, although an impaired QoL is common in long-term follow ups.
