The use of lasers in pediatric surgery.
This report is a condensation of the Fred McLoed Lecture given at the Annual Meeting of the Canadian Association of Paediatric Surgeons. It briefly cites the basic fundamentals of lasers, the characteristics of those used in surgery, and their delivery systems. The advantages of laser surgery include the sealing of blood vessels, lymphatics, and nerve ends when used for cutting. This results in a relatively dry field of surgery and less postoperative pain. There is reduced opportunity for contaminants in a clean wound, and no spreading of infection in a contaminated one. Surgery can be carried out in confined areas in a drier field of view, and can be brought to small areas by fiberoptic cables. Highly precise and localized microsurgery is possible. The use of lasers is indicated in operations where significant blood loss is expected and in patients with bleeding tendencies. It is useful in surgery for malignant disease and through highly infected tissue. Other general indications are discussed. Specific surgical procedures where lasers have been useful include treatment of hemangiomas, surgery of the tongue, repair of pectus excavatum, partial splenectomy and splenic repair, hepatic lobectomy and hepatic repair, and resection of adrenal tumors. Lasers have also been useful in partial nephrectomy, excision biopsy, revision or closure of ileostomy or colostomy, endorectal mucosectomy, posterior sagittal anorectoplasty, treatment of condyloma acuminata, burn wound debridement, and infected tissue debridement. Anticipated uses include vascular, biliary tract, and intestinal repair and anastomoses, and photodynamic therapy (PDT) of neoplasms.
