Medical survival censored data of 524 patients were evaluated in order to: 1) compare two types of surgical techniques and 2) develop the integrated survival model, who can adjust for other patients characteristics. Evaluated data come from patients who underwent colectomy in the University Hospital in Ostrava. There are used two basic surgical techniques for the colectomy: either classical (open) or laparoscopic operation. Basic questions which arise at the colectomy operation are which type of operation to choose to guarantee longer overall survival time and what are the other parameters, which can influence the survival time of the patient. The semiparametric Cox proportional hazards model was used to answer these questions.
