BACKGROUND: Complications 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.
METHODS: 21 esophagus samples from 21 male lambs aged 12 months were used in vitro for the study. All esophageal samples were matched to have a length of 120 mm. 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.
RESULTS: Post-op esophageal lengths were measured as 227, 210 and 200 mm for VM, LM and KM, respectively. Elongation amount per incision was measured as 5.1, 4 and 3.34 mm, again in previous order of VM, LM, and KM. Finally, perforation pressure following VM, LM, and KM was measured as 460, 400, and 410 mmHg.
CONCLUSION: VM 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.
