Natural Orifice Trans-Pharyngeal Diverticulum Thoracic Sympathectomy:a Pilot Study in Animal Model
Fan Zhi-ning, Tang X. Wei, Xiang Wang
Background and objective: Thoracoscopic sympathectomy is now widely used for the surgical treatment for patients with disabling palmar hyperhidrosis. This method requires a transthoracic approach to permit ablation of the thoracic sympathetic chain. We tried to develop a less invasive, trans-pharyngeal diverticulum endoscopic technique for a sympathectomy in the swine model.
Methods:Ten healthy domestic swines were used for this nonsurvival study, followed by autopsy and histological investigation. A double-channel gastroscope was introduced into the pharyngeal diverticulum, then a biopsy forcep and balloon were used to create a small pharyngeal diverticulum perforation, through which the gastroscope entered into the mediastinum and chest. The sympathetic chain was identified at the 3 or 4 thoracic level and was ablated or transected. After the completion of the procedure, the animals were killed.
Result:The ablation of sympathetic chain was successfully completed in 9 of 10 swine, as confirmed by autopsy and histology. In 1 swine, muscle fibers were inadvertently transected. On average, it took 56.1 21.3 minutes to get into the chest, whereas the sympathectomy was performed in less than 4 minutes in all cases. During the whole procedure, there was no major complictions happened in the swines.
Conclusion:Natural orifice trans-pharyngeal diverticulum thoracic sympathectomy is technically feasible, simple, and can be performed in a porcine model.
