A major preoperative potentially reversible risk factor for severe postoperative morbidity is nutritional status, even; it is considered recently the missed ring in the all available morbidity prognostic indices. This was typically proving in other kinds of cancer. For instance, it has been shown that patients at nutritional risk have had significantly postoperative complications 10% as high as compared to those not at nutritional risk as well as elevated rates of anastomotic leak and infections after colorectal surgery. Likewise, in an observational trial, there was an increased risk of postoperative complications in malnourished patients undergoing pneumonectomy for lung cancer.Furthermore, the hazardous impact of malnutrition does extend beyond the potential morbidity to increased cost, hospital stay, and readmission rates. Not surprisingly, the prognostic nutritional index was shown, additionally, to influence the survival after total gastrectomy for patients with gastric cancer.
