- W2563177313 abstract "espanolLas neoplasias presentan una gran incidencia entre las diferentes patologias que afectan al tracto gastrointestinal. Algunas de ellas, como la ectasia vascular antral gastrica o la proctitis actinica pueden requerir una intervencion quirurgica endoscopica que generalmente se realiza mediante Coagulacion con Argon Plasma o radiofrecuencia. Entre los inconvenientes asociados con estas tecnicas destacan un area de tratamiento reducida e incompatibilidades con la resonancia magnetica. La cirugia optica podria salvar dichos inconvenientes y permitir un control mas preciso de los efectos tanto ablativos como coagulativos del tratamiento. En este trabajo se estudia la aplicacion de cirugia laser para la reseccion de tumores en el colon mediante un modelo predictivo que integra tanto la propagacion de la radiacion laser como el proceso de ablacion optica. Los resultados obtenidos permiten analizar el volumen tumoral eliminado en diferentes tejidos malignos bajo diferentes configuraciones del laser. Lo que posibilita una planificacion optima del tratamiento EnglishNeoplasms incidence is high among different pathologies that affect the gastrointestinal tract. Some of them, such as gastric antral vascular ectasia or actinic proctitis may require an endoscopic surgical procedure that is usually performed by means of Argon Plasma Coagulated or radiofrequency. The reduced treated area or magnetic resonance incompatibility are some drawbacks associated with these conventional techniques. Optical surgery could help solve such problems and would provide a more accurate control of both ablative and coagulative effects. In this work, laser surgery application to the resection of colon tumors is studied by a predictive model that integrates both the laser radiation propagation and the ablation process. Results show the removed tumor volume taking into account different types of malignant tissues under different laser settings. Therefore they are of great interest in treatment planning to select the optimum source parameters to remove a particular tumor." @default.
