BackgroundComplications such as stricture, leakage, recurrent tracheoesophageal fistula and mucosal pouch are commonly seen in myotomy techniques used for long-gap esophageal atresia (LGEA) treatments. Therefore, we think that there is a clear need for other techniques which would enable us to create more robust and longer esophagus in such cases. In this study, we reviewed multiple V-myotomy (VM) technique and the differences of the said technique with Livaditis circular myotomy (LM) and Kimura spiral myotomy (KM) techniques using literature as an aid.Methods21 esophagus samples from 21 male lambs aged 12months were used in vitro for the study. All esophageal samples were matched to have a length of 120mm. Samples were divided into 3 groups of 7 and VM, LM and KM techniques were used in each group, respectively. Post-op esophagus lengths, elongation amount with each incision and perforation pressures were measured.ResultsPost-op esophageal lengths were measured as 227, 210 and 200mm for VM, LM and KM, respectively. Elongation amount per incision was measured as 5.1, 4 and 3.34mm, again in previous order of VM, LM, and KM. Finally, perforation pressure following VM, LM, and KM was measured as 460, 400, and 410mmHg.ConclusionVM was found to significantly increase total esophagus length and elongation per incision over LM and KM. In addition, VM was also shown to have a higher perforation pressure. Although in vivo live animal studies are required, we can say that VM can be used to create longer and robust esophagus.
