ASA American society of anaesthesiologist-classification of comorbidity
a“Yes” related to comorbidity means that the patient had one or more of the specified comorbidities below. Ischemic heart disease (IHD), chronic obstructive pulmonary disease (COPD), Obesity classified as BMI > 30
bCancer diagnosis of any kind from 3 years before until 1 year after surgery
cThe cohort contains 41 patients who had EL more than once (1 patient had 4 operations, 4 patients had 3 operations and 36 patients had 2 operations), these 41 patients therefore represent 88 operations. Mortality variable has been adjusted so that an expiry only can be attributed as a result to the last of a patients operations
