Dehiscence is a feared complication after major surgeries. Patient who had undergone coronary artery bypass grafting developed saphenectomy's dehiscence on lower limb with edema and pain on the 15 th postoperative day. Conventional treatment had been initially performed without clinical improvement. On the 30 th postoperative day only Low Level Laser Therapy (LLLT) was applied punctually around surgical wounds edge. The results revealed granulated tissue, reduction of inflammatory process and analgesic effect since the first application. In this pilot study, LLLT has shown a considerable role as a wound healing agent, through a new proposal for efficient, safe and noninvasive therapy.Descriptors: Laser therapy, low-level. Surgical wound dehiscence. Wound healing. ResumoDeiscência é uma complicação temida em cirurgias de grande porte. Paciente submetida a revascularização miocárdica evoluiu com deiscência de safenectomia em membro inferior, edema e dor no 15º dia pós-operatório (PO), tendo sido realizado inicialmente o tratamento convencional no ambulatório sem melhora clínica. No 30º PO, aplicou-se somente Laser de Baixa Intensidade (LBI) ao redor da borda da ferida, pontualmente. A lesão respondeu com tecido de granulação, diminuição do processo inflamatório e analgesia desde a primeira aplicação. Neste estudo piloto, a laserterapia mostrou ter um papel importante como agente facilitador de cicatrização, por meio de uma terapia não-invasiva, eficaz e segura.Descritores: Terapia a laser de baixa intensidade.

Objective: To analyze the tissue repair behavior after corrective surgical incision in neonates submitted to low-level laser therapy, in an attempt to diminish the incidence of postoperative dehiscence following the surgery for myelomeningocele performed immediately after birth. Methods: It is a prospective pilot study with 13 myelomeningocele patients submitted to surgery at birth who received adjuvant treatment with low-level laser therapy (Group A). Diode laser C.W., λ = 685t nm, p = 21 mW, E = 0.19 J was punctually applied along the surgical incision, summing up 4 to 10 J energy delivered per patient, according to the surgical wound area and, then, compared with the previous results, which were obtained from 23 patients undergoing surgery without laser therapy (Group B). results: This pilot study showed a significant decline in dehiscence of surgical wounds in neonates submitted to low-level laser therapy as compared to controls (7.69 versus 17.39%, respectively), demonstrating this is an effective, safe and noninvasive treatment method. conclusion: This new adjuvant therapeutic proposal with low-level laser therapy aided healing of surgical wounds, preventing morbidities, as well as decreasing hospital stay, which implies cost of reduction for patients and for the institution.Keywords: Infant, newborn; Congenital, hereditary, and neonatal diseases and abnormalities/surgery; Laser therapy, low-level; Surgical wound dehiscence/ prevention & control; Meningomyelocele/surgery; Guided tissue regeneration/methods; Postoperative complications reSUMO Objetivo: Analisar o comportamento da reparação tecidual de incisão cirúrgica corretiva em neonatos submetidos ao laser de baixa intensidade, auxiliando a redução de incidência de deiscência pós-operatória de correção cirúrgica de mielomeningocele realizada imediatamente após o nascimento. Métodos: Estudo piloto, prospectivo, com 13 pacientes operados ao nascimento de mielomeningocele e submetidos ao laser de baixa intensidade como adjuvante. Foi aplicado, ao longo da incisão cirúrgica, o laser de diodo C.W., λ = 685 nm, p = 21 mW, com E = 0,19 J por ponto, totalizando valores de energia entregue por paciente entre 4 e 10 J, de acordo com a área da cicatriz cirúrgica, e comparando com os resultados obtidos previamente de 23 pacientes operados sem a terapia com o laser (Grupo B). resultados: Este estudo revelou significativa redução de deiscências no pós-operatório de neonatos, quando submetidos ao laser de baixa intensidade comparados ao controle (7,69 versus 17,39%, respectivamente), evidenciando ser um método de tratamento eficaz, seguro e não-invasivo. conclusão: Esta nova proposta terapêutica adjuvante com o laser de baixa intensidade auxiliou na reparação tecidual da ferida operatória, evitando morbidades, além de diminuir o tempo de internação, sinalizando possível redução de custos tanto para os pacientes quanto para a instituição.Descritores: Recém-nascido; Doenças congênitas, hereditárias e neonatais e anormalidades/cirurgia; Terapia a laser de baixa i...
Background/Aims: The use of low-level laser therapy (LLLT) in neurosurgery is still hardly disseminated and there are situations in which the effects of this therapeutic tool would be extremely relevant in this medical field. The aim of the present study is to analyze the effect of LLLT on tissue repair after the corrective surgical incision in neonates with myelomeningocele, in an attempt to diminish the incidence of postoperative dehiscences following surgical repair performed immediately after birth. Materials and Methods: Prospective pilot study with 13 patients submitted to surgery at birth who received adjuvant treatment with LLLT (group A). A diode laser CW, λ = 685 nm, p = 21 mW, was applied punctually along the surgical incision, with 0.19 J delivered per point, accounting for a total of 4–10 J delivered energy per patient, according to the surgical wound area and then compared with the results obtained in 23 patients who underwent surgery without laser therapy (group B). Results: This pilot study disclosed a significant decline in dehiscences of the surgical wounds in neonates who were submitted to LLLT (7.69 vs. 17.39%). Conclusion: This new adjuvant therapeutic modality with LLLT aided the healing of surgical wounds, preventing morbidities, as well as shortening the period of hospital stay, which implies a reduction of costs for patients and for the institution.
LLLT was valuable in preventing prodromal complications in saphenectomy post myocardial revascularization.
