良性脾臓病変における全血流閉塞を伴う腹腔鏡下部分脾臓摘出術の適用

Executive Industry Relevance

Hemorrhage control during laparoscopic partial splenectomy presents a critical challenge for surgical innovation, especially in the context of fragile, highly vascularized tissues. The described total blood flow occlusion technique directly addresses intraoperative risk, supporting reproducibility and procedural standardization in surgical device and technique development. This approach is relevant for biopharma teams focused on enabling safer, more predictable surgical interventions in preclinical and translational research settings.
