In Poland, about three thousand women are diagnosed with ovarian cancer every year. Patients are often operated on in the condition in which disease progression in non limited to the sexual organ only, so in order to carry out a radical surgery a part of the digestive system needs to be removed. A permanent problem during the post-surgical period is the introduction of oral feeding. Despite the fear of side effects of such an action (flatulence, stomach ache, vomiting, risk of anastomosis dehiscence), early and gradual introduction of oral feeding – after the auscultation of the abdomen – positively influences the reduction of protein catabolism, reduces patient malnutrition, increase the blood flow through the mesenteric vessels, does not increase the risk of intestinal anastomosis dehiscence, and thus it reduces the tme a patient spends at hospital.
