Endoscopic septum division of tubular esophageal duplication in two children and systematic review

Tubular esophageal duplication is a rare congenital malformation The surgical treatment of this lesion can be challenging. We aimed to present our experience in two cases with tubular esophageal duplication. Both cases were endoscopically treated by a dual knife. The first patient underwent a single, while the second patient required three sessions of endoscopic septum division using an electrosurgical knife. Both showed satisfactory clinical, radiological and endoscopic response to treatment. Moreover, a systematic literature review has been performed. To identify all available studies, a detailed search on tubular esophageal duplication was performed according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. Tubular esophageal duplication was reported in 16 pediatric cases in 14 studies in the literature. Surgery was applied to 10 of these cases and endoscopic treatment was applied to two of them. In the follow-up, nine patients who underwent surgical treatment and two patients who underwent endoscopic treatment were uneventful. Tubular esophageal duplications can be successfully treated endoscopically. Endoscopic septum division is a minimally invasive procedure that allows full anatomical recovery and satisfactory therapeutic response.
