Input: A total of 4092 titles were screened and 14 full text reports reviewed; a single small study met the inclusion criteria. In the included RCT, 40 women (35 with ovarian cancer) had extensive elective surgery including bowel resection for treatment of gynaecological malignancy. Randomisation was made to either early oral feeding (oral fluids in the first 24 hours, solid foods on the following day) or to a 'traditional' feeding regimen where oral fluids and foods were delayed until there was evidence of bowel function. Most women in the early feeding group (14/18) were able to resume eating solid food one day after surgery. This resulted in a significantly shorter hospital stay with no increase in postoperative complications or change in quality of life measures in comparison with the women on the 'traditional' feeding regimen. The incidence of nausea and vomiting during the postoperative stay was similar in both groups and was noted in slightly more than half of the women. Overall survival was evaluated until 30 days following discharge from hospital; in this period, there was one death of a woman who had been in the 'traditional oral feeding' group, cause of death was not noted. We assessed risk of bias and found no high risk of bias was identified in the methodology and reporting of the included study, although there was an increased risk of bias due to the small size of the study in which not all of the women had ovarian cancer. Although women with ovarian cancer have been shown to be at risk of malnutrition, there is a lack of evidence derived from RCTs evaluating the identification, assessment and treatment of malnutrition during the perioperative phase of treatment. There is evidence from one small study that some women with ovarian cancer undergoing surgery with associated bowel resection may safely commence oral fluids within 24 hours of surgery and solid foods on the following day. Further research is required, including a RCT, to generate guidance concerning the treatment of malnutrition in this patient group.
Output:

In this review, the authors looked for studies (randomised controlled trials (RCTs)) from around the world to find out how women with ovarian cancer were assessed to see if they were eating and drinking well and what help they may be given with nutrition before or after surgery. A lack of information was found on this topic. One RCT was found where a small group of women (40 including 35 with ovarian cancer) requiring extensive elective surgery for gynaecological cancer including surgery to the gut, were able to restart eating normal foods on the day after surgery. They were able to leave hospital earlier and did not have more complications in the month after surgery than women who were not allowed to resume eating normal foods until at least three days after the operation. More studies are needed to confirm whether restarting normal eating one day after surgery can be recommended for women having surgery for ovarian cancer. More research is needed to provide information about how to identify and treat problems of malnutrition in women with ovarian cancer.
