RESUMO
Introduction: Many studies on short-term efficacy of laparoscopic antireflux surgery (LARS) have shown good to excellent results on reflux symptom control and health-related quality of life (HRQoL). Prospective studies on the long-term efficacy, however, are scarce and indicate that the efficacy of symptom control may decline over time. The aim of this study is to assess the 2-year outcome on reflux symptoms and HRQoL after LARS. Materials and Methods: Between 2011 and 2013, 25 children (12 males, median age 6 [2-18] years) with proton pump inhibitor-resistant gastroesophageal reflux disease were included in a prospective longitudinal cohort study. To assess reflux symptoms and HRQoL, patients and/or their caregivers were asked to fill out the validated age-appropriate gastroesophageal reflux symptom questionnaire and Pediatric Quality of Life Inventory™ before, 3 months, 1 year, and 2 years after LARS. Results: Two years after LARS, 29% of patients had moderate to severe reflux symptoms compared with 92% (P < .001) before operation and 12% 3-4 months after operation (P = .219). The significant increase in HRQoL shortly after fundoplication (80.0 compared with 69.5 (P = .004)) is not observed after 2 years (72.0 compared with 69.5, P = .312). Correlation between the impaired HRQoL scores and the recurrence of symptoms could not be verified. Conclusions: Although the efficacy of LARS tends to deteriorate after 2 years, LARS is still effective in controlling reflux symptoms in the majority of patients. The short-term improvement in HRQoL after LARS appears to be transient.
