RESUMEN
BACKGROUND: Oesophageal achalasia is a rare disorder in childhood. Common treatments in adults include oesophageal cardiomyotomy (laparoscopic or open) with fundoplication. We aimed to assess the results of laparoscopic oesophageal cardiomyotomy without fundoplication for treatment of achalasia in children. METHODS: We reviewed the results of laparoscopic oesophageal cardiomyotomy between January 1998 and June 2008. Patients below the age of 18 years, who had undergone laparoscopic oesophageal cardiomyotomy without an anti-reflux procedure by a single surgeon, were identified. Data were collected from patient notes. Results are reported as median (range). RESULTS: There were 20 patients (13 males and 7 females). Median age at surgery was 12 years (5-15 years) and weight was 38 kg (15-53 kg). Median duration of symptoms before surgery was 2.4 years (1.5-5 years). Duration of surgery was 96 min (60-160 min). Four patients (20%) required conversion to the open technique. In the remaining 16 children, fluids were started at a median of 7 h (6-8 h) post-operatively, and solid feeds were commenced at 22 h (20-24 h). Median length of hospital stay was 3 days (1-5 days). Median length of follow-up was 60 months (8-114 months). None of the patients had evidence of gastro-oesophageal reflux post-operatively. Five patients (25%) continued to experience dysphagia, with one of them also experiencing vomiting. Two patients were found to have oesophageal stricture and three patients were found to have oesophageal dysmotility. The remaining patients are asymptomatic. CONCLUSIONS: These results suggest that laparoscopic oesophageal cardiomyotomy is a valid treatment in children with achalasia. In our experience, an adjunctive anti-reflux procedure is not required, as there was no evidence of post-operative gastro-oesophageal reflux in all patients. Oesophageal stricture and dysmotility account for residual post-operative symptoms.
