Micro-pressure-suction-irrigation system (MPSIS), introduced by Luedecke et al, is an instrumentation for the direct transnasal pituitary procedure. We improved this system for use in Japan. The irrigation system can effectively clean the operating field by one-hand manipulation and dissect tumor tissue by its rapid flow. The pressure of suction and irrigation can be adjusted respectively by a device in the handpiece. The MPSIS is applicable to different stages of intervention because it is equipped with separate tips of various diameters, lengths and angles. This system is especially useful in combination with a micromirror or an endoscopy for direct inspection of the eccentric tumor sites such as the cavernous sinus, the upper part of the planum sphenoidale, or the posterior suprasellar regions. The use of the MPSIS helps to avoid injury to normal tissue structures, and prevents tiny soft microadenoma from being lost during preparation. We have proved the suitability and usefulness of the MPSIS in 23 surgical interventions for transnasal microsurgery of pituitary adenomas.
微压吸引冲洗系统（MPSIS）由吕德克等人引入，是一种用于经鼻垂体直接手术的器械。我们对该系统进行了改进，以便在日本使用。该冲洗系统可通过单手操作有效清洁手术视野，并通过其快速流动来分离肿瘤组织。吸引和冲洗的压力可通过手持器械中的装置分别进行调节。MPSIS配备有不同直径、长度和角度的单独尖端，适用于不同阶段的干预。该系统与微型镜子或内窥镜结合使用时，对于直接检查海绵窦、蝶骨平台上部或鞍上后部等偏心肿瘤部位特别有用。使用MPSIS有助于避免对正常组织结构造成损伤，并防止在准备过程中微小的软微腺瘤丢失。我们已经在23例经鼻垂体腺瘤显微手术中证明了MPSIS的适用性和实用性。
