DBSurg is a software for recording descriptions of surgical procedures based on a previously defined ontology [refs neuroimage + CAS]. DBSURG allows prospective and retrospective descriptions of planned and/or performed surgical procedures. Queries capabilities provide the neurosurgeon with tools to browse the database and to analyse occurrences of dedicated surgical characteristics. The last version that we developed, is used for different projects following French or English language interface. DBSurg is based on php and PostGreSQL.
