The invention is suitable for the field of a medical internet, and provides a synchronization method for medical LIS system inspection reports, and a preposed server. The synchronization method comprises the steps of: refreshing a view at every fixed time interval, and reading newly added patient serial number, inspection serial number and a storage path of inspection port images when discovering that newly added data exists in the LIS system; reading the inspection port images according to the storage path of the inspection port images, and storing the inspection port images into a folder; scanning the LIS system at every preset time interval to find out whether newly added inspection port images, namely, an incremental file exists; and synchronizing the incremental file, the corresponding patient serial number and the corresponding inspection serial number to a cloud server by utilizing a sockets port combined with a completion port if the incremental file exists. The synchronization method achieves sharing of inspection reports of all hospital LIS systems, provides a convenient way for the transfer treatment of patients, and achieves self-data storage and management by the patients.
