Abstract: Recent advances in optical techniques have created a great range of possibilities for diagnosis and therapeutics in liver related diseases. With the uses of efficient light sources like lasers and LEDs (Light Emitting Diodes) it is possible to employ the light-tissue interaction to promote hepatic tissue regeneration after partial hepatectomy, to detect hepatocarcinoma and steatosis by utilizing optical fluorescence, to evaluate the metabolism of the liver during hepatic transplantation as well as to treat liv… Show more

“…Here, despite extensive prior therapy, tumor ablation with good wound healing is possible. Recently, Photofrin PDT has demonstrated a doubling of survival in randomized trials for patients with bilary cholangiocarcinoma [49][50][51]. Prolonged survival with a high quality of life is possible through outpatient treatment.…”

“…Denominou-se o novo campo como fotobioestimulação. 2,6,7 A fototerapia com laser mostrou-se eficaz no tratamento de úlceras de membros inferiores, na neoformação vascular, proliferação de fibroblastos, reparo ósseo, regeneração de nervos, 19 tendo também vasta aplicação em oncologia sob a denominaçao de terapia fotodinâmica. 17 Os mecanismos de interação do laser com a matéria são caracterizados como fotoquímicos, fototérmicos e fotomecânicos.…”

“…[1][2][3][4] Tanto a luz convencional, quanto o LEDlight-emitting diode-e o laser, com suas propriedades ópticas diferentes, promovem efeitos semelhantes nas organelas celulares levando ao aumento da eficiência da cicatrização de feridas, da capacidade energética mitocondrial hepatocelular e da regeneração hepática. [1][2][3][4][5][6][7] O fígado tem extraordinária capacidade de regeneração diante de vários tipos de desafios ou lesões. A perda tecidual rapidamente desencadeia o processo regenerativo até que o peso original seja recuperado.…”

“…Several studies have shown an effective interaction between light and biological tissues, the liver in particular [1][2][3][4][5] .Conventional light, as well as light-emitting diodes (LED) and laser, with their different optical properties concerning light production and delivery have similar effects on cell organelles, leading to increased efficiency of wound healing, of hepatocellular mitochondrial energy capacity, and of hepatic regeneration 2,[3][4][5][6] . The partial loss of hepatic tissue rapidly triggers the regenerative process until the original weight is recovered 7,8 .…”

“…The detection of the response of the liver to various challenges such as hepatitis, intoxication, hepatic resections and liver transplantation is of a mythological nature 9,10 and raises extremely interesting aspects about the hepatic coherencein meeting challenges and overcoming obstacles. Laser phototherapy has proved to be effective for neovascularization, fibroblast proliferation, bone repair and nerve regeneration, also with broad applications to oncology in the form of photodynamic therapy [2][3][4] .…”
