Study of Safety and Efficiency of the Use of Neutral Argon Plasma in Cyto-reduction of Miliary Implants in the Peritoneal Surface.

"Evaluation of the mesentery or peritoneum area infiltrated by miliary implants that is going to be treated. Determination of the PCI. Collection of several samples of the mesenteric peritoneum or parietal peritoneum with tumor involvement (implants between 1-2.5mm of diameter).~It will established a matrix which will be divided into 12 quadrants where the tissue with implants will be placed and it will be treated according to specific power (80-100%), and for an action time of 2-4 seconds or until macroscopic tumor destruction. For each power, application of Plasmajet at 1, 2 and 3 cm from the target tumor tissue.~The in-vivo effect will be evaluated with the use of ball-tip in terms of damage to the serosa or vascularization of the mesentery."
