N2 - Object. The purpose of present study is to report the safety and efficacy of piezo actuator-driven pulsed water jet (ADPJ) system in neurosurgery and spinal cord surgery. Methods. The ADPJ system have been used as a part of standard procedure for brain and spinal cord pathologies after approval from internal review board of Tohoku University Hospital. Results. The system have been used in 5 malignant glioma, 6 meningioma, 1 callosotomy for intractable epilepsy, 1 cerebrovascular disease, and 5 spinal cord tumor. There was no complication related to the use of the system. Tissue could be dissected under preservation of fine arteries (diameter 200 microns). The present power was not enough for certain pathologies, especially for hard lesions. Conclusion. Although additional effort to enhance efficacy is necessary, present study indicated that the ADPJ have possibility to become novel surgical tools to assist maximal lesion removal and preserving postoperative function.
