In this paper the Authors describe their own experience in applying informatics at the Surgical Division III of Azienda Policlinico Universitario of Messina. After a discussion about existing hardware (LAN of PC) and daily used software (commercial suite) for managing the clinical reports and correlated data (images, medical prescription, reservations, and so on), their conclusion is that a great development on this way will be possible with extension of the services to all the business network and then to WAN as Internet.
