Reflectance spectra analysis for mucous assessment

Table 1 Application of indicating relative hemoglobin concentration and saturation function to surgical operation

Department	Target disease	Expected results
Neurosurgery	(1) Brain tumor; and (2) Cerebral infarction: Detection of diseased area	(1) Improvement of postoperative outcome in terms of oncologic and functional preservation; and (2) Diagnostic improvement
Urology	Partial nephrectomy of renal tumor: Detection of area of ischemia secondary to occlusion of a dominant artery	Improvement of postoperative outcome in terms of oncologic and functional preservation
Gynecology	Trachelectomy for cervical cancer: Assessment of relativity between blood flow and fertility after anastomosis	Decision on the optimal reconstruction method
Gastroenterology surgery	Organ resection for gastrointestinal cancer: Assessment of the organ after resection and reconstruction. Strangulation ileus and hernia: Conformation of organ and tissue viability-related blood flow and oxygen saturation	Reduction of postoperative complications by assessment of real-time organ viability
Plastic surgery	Skin transplantation, including breast reconstruction: Confirmation of transplanted organ and tissue viability-related blood flow and oxygen saturation. Keloid scar: Relative assessment of keloid scar formation-related blood flow and oxygen saturation	(1) Improvement of reconstructive surgery; and (2) Establishment of knowledge on the oxygen saturation of wound tissue for prevention of keloid formation
Ocular	Diabetic retinopathy: Evaluation of the oxygen saturation of fundus blood vessels	Establishment of evaluation and treatment for diabetic retinopathy
