Since 1987 when this procedure began in France an them became popular all over the world, it isn’t any doubt that is the best choice for Cholecystectomy in patients with cholelytiasis. We began our experien-ce in 1996, they have been operated 562 patients by this technique over 1839 cholecystectomies until April 2004, which corresponds to a 31%. We have suffered all the changes in the interpretation and application of law 100, which excludes the procedure from the State Obligatory Health Insurance and many Promoting health Enterprises prohibit it’s practice, essentially because they igno-re the good results it has which are similar to open cholecystectomy. We registered our patients and procedures since the beginning of this experience for evaluation, also to compare it with the medical literacy about it and to verify by ourselves the benefits of minimal invasive surgery.
