ABSTRACT
BACKGROUND:
Although esophageal achalasia has been historically treated by Heller myotomy, endoscopic esophageal dilatations are nowadays often the first-line treatment in children. The aim was to assess whether performing an endoscopic dilatation before a Heller myotomy is associated with higher risks of esophageal perforation in children.METHODS:
A retrospective multicentric study was performed, including children that underwent a Heller myotomy (2000-2022, 10 centers). Two groups were compared based on the history of previous dilatation before myotomy. Outcomes esophageal perforation (intra-operative or secondary) and post-operative complications requiring surgery (Clavien-Dindo III). Statistics Comparisons using contingency tables or Kruskal-Wallis when appropriate. Statisticalsignificance:
p-value < 0.05.RESULTS:
A Heller myotomy was performed in 77 children (median age 11.8 years), with prior endoscopic dilatation in 53% (n = 41). A laparoscopic approach was used in 90%, with associated fundoplication in 95%. Esophageal perforation occurred in 19% of children (n = 15), including 12 patients with intra-operative mucosal tear and 3 with post-operative complications related to an unnoticed esophageal perforation. Previous endoscopic dilatation did not increase the risk of esophageal perforation (22% vs 17%, OR 1.4, 95%CI 0.43-4.69). Post-operative complications occurred in 8% (n = 6), with similar rates regardless of prior endoscopic dilatation. Intra-operative mucosal tear was the only risk factor for post-operative complications, increasing the risk of complications from 5 to 25% (OR 6.89, 95%CI 1.38-31.87).CONCLUSIONS:
Prior endoscopic dilatations did not increase the risk of esophageal perforation or postoperative complications of Heller myotomy in this cohort of children with achalasia. Mucosal tear was identified as a risk factor for post-operative complications.Palabras clave
