[Construction and application of evaluation system of laparoscopic colorectal surgery based on clinical data mining]

To construct a clinical database for laparoscopic colorectal surgery in Chinese population using computerized technique.A clinical database system was constructed and used in multi-/single-center studies on laparoscopic colorectal surgery.The data of more than 1200 cases in the Nanfang Hospital during the past year were collected retrospectively. The database was used as the platform for "Southern China Laparoscopic Colorectal Surgery Study Group (SCLCSG)" and was used in the first stage of the clinical research of "Multicenter retrospective study of laparoscopic and open procedure for colorectal cancer" among 11 hospitals in Southern China. In order to test the system, the database was also used in "comparative study on oncologic results of laparoscopic versus open radical resection for rectal carcinoma".The evaluation system is reliable and efficient. This system has established a clinical database for laparoscopic colorectal cancer surgery and can be widely applied for the clinical research for colorectal cancer.
