Preoperative and postoperative nutritional status of patients following pelvic exenteration surgery for rectal cancer

SummaryBackground and aimsMalnutrition is prevalent in patients undergoing major abdominal surgery, however, has not been investigated in patients undergoing pelvic exenteration surgery. This prospective observational study aimed to determine the nutritional status of patients undergoing pelvic exenteration surgery.MethodsPatients undergoing pelvic exenteration surgery between September 2009 and November 2011 were recruited. Nutrition assessment was performed using validated measures including subjective global assessment. Identical nutritional measurements were taken preoperatively and at the time of discharge from hospital. A phone review was conducted one month after discharge.ResultsEighty eight patients were recruited to the study. The prevalence of malnutrition as determined by the subjective global assessment was 24% on admission and 51% at the time of discharge. Percentage weight change significantly deteriorated during their admission and continued after discharge. Preoperative BMI was the only significant factor in predicting percent weight loss at both discharge and one month after discharge.ConclusionsThe majority of patients undergoing pelvic exenteration surgery for rectal cancer are well nourished on admission however their nutritional status significantly deteriorates during their hospital stay and in the early postdischarge period. Nutritional interventional are needed pre and postoperatively to improve outcomes for these patients.
