BLOOD LOSS, SECONDARY, TUMOUR, COMPLICATIONS
After the patient gave his or her informed consent, the demographic and basic data (sex, age, weight, height, medical history, current medication, comorbidities, ASA classification, ECOG status), and primary tumour characteristics (UICC classification, date of diagnosis, location, previous treatments including chemotherapy, target therapy, radiotherapy, and surgery) are evaluated and documented by the investigator. Intraoperative parameters such as length of operating time, blood loss, blood transfusion requirement, and conversion to open surgery are recorded.During each study visit and on the day of discharge, primary and secondary endpoints and SAEs are evaluated and documented according to the eCRF. During the postoperative visits, routine blood tests (including haemoglobin concentration, leucocyte count, and serum C-reactive protein) will be performed. Furthermore, data that will be collected within these study visits include at least the following: postoperative assessment, ICU length of stay, grading of complications according to Clavien‒Dindo Classification, morbidity and mortality within the hospital stay, length of hospital stay, drain secretion volumes, postoperative examinations (e.g. chest X-rays, CT scans), and physical activity of the patient. The physical activity of the patients is collected using a CE-certified fitness tracker device, which measures the number of steps, distance, and activity minutes during the hospital stay. The transmission of these data works automatically via synchronization with a tablet or is carried out by the investigators before discharge.
