Résumé
BACKGROUND: Replacement conduits carry significant morbidity in long gap esophageal atresia. Surgical myotomies can lengthen the esophagus, but have not gained widespread adoption due to long-term dilatation. The aim of this study is to assess the feasibility of an emerging minimally invasive technique of submucosal endoscopic myotomy for esophageal lengthening. METHODS: Bilateral submucosal lengthening endoscopic myotomies (BSLEM) were performed in three swine. Circular esophageal muscle fibers were selectively divided in a bilateral 3 cm longitudinal pattern. Ex-vivo tensile testing was performed on the BSLEM and compared with three circular myotomies, three spiral myotomies, and three controls. RESULTS: BSLEM was completed in all cases with one esophageal microperforation. The mean operating time was 38 minutes. Over physiologic force ranges of 0 to 100 g, the percentage esophageal elongation was significantly different among the four groups (p
