As regards specificity (coincidence between lesions detected and real lesions), the Hospital gave the second best result with 92% of hits only one point less than the best. As regards positive predictive value (the probability of suffering from a lesion alter obtaining a positive result on testing, the Navarre-based centre also led the ranking of the eight hospitals taking part - 94%.

Conclusions and proposals for improvement

Doctor Muoz stated that this is the first study carried out on this technique and the team is aware that the way the procedure is undertaken should be improved. In this sense, the improvements put forward as a result of the study focus on the importance of a more thorough cleaning of the colon before initiating the exploratory test, given that, with conventional colonoscopy, the specialist can clean relatively with water some of the dirty areas found during the exploration something which cannot be done with the capsule -, but if there is a lesion hidden below a concentration of dirt, the lesion will not be observed. In fact, better results have been obtained with those patients that have a cleaner intestine.

Moreover, doctor Muoz emphasised the need to improve the endoscopic capsule technique, using pharmaceutical drugs that regulate intestinal transit and, in this way, enabling a better control of the passage of the device through the digestive tract in such a way that it is more rapid through the small intestine and reaches the colon that much sooner.

Other aspects on which the capsule manufacturers are working to improve the device is the capture of the maximum number of images per second - currently fo
