A group with jejunostomy (J + group) and a group without jejunostomy (J - group) were compared. Continuous variables are expressed as the mean and standard deviation. Categorical variables are expressed as numbers and percentages. Weight loss is expressed as an absolute and a relative average value. PNI: Prognostic nutritional index; BMI: Body mass index.
