Abstract：The morbidity of the elders with chronic diseases increased obviously. Tumor - related deaths have compromised to
28. 6% of all - cause deaths for elder population. Patients over 65 years old have occupied a ratio about 25% - 33% of all the
hospitalized patients in department of surgery. Meanwhile surgery-related complications mortality re-admission rate and commercial
burden all increased significantly. For this reason choosing adequate tools aiming at the aged patients for the nutritional screening and
evaluation before operation and predicting surgery - related risks and outcomes will contribute crucially to reduce the morbidity of
post-operative complications and mortality while enhance prehabilitation efficiently further save medical resources and improve the
efficiency of society. This article introduced the circumstance of graying society in China and the evaluations of nutrition tools which
aim at elderly patients in Department of Digestive Surgery for prediction perioperative risks and outcomes. Several single -centered
researches have implicated that geriatric nutritional risk index GNRI played a positive role in predicting the perioperative risks and
outcomes of elderly patients with colorectal cancer or hepatic cell carcinoma. To be specific GNRI may actually be beneficial to
evaluate pre - operatively nutritional status and predict the risks of severely surgery - related complications overall survival and
recurrence-free or progression - free survival. Five meta - analyses studies searched at present elucidated a common conclusion in
consistent with the single-centered researches mentioned above. However the four articles all emphasized that the original researches
included in analysis were mostly retrospective designed which means limited sample sizes and high heterogeneity in integrated
data. Therefore it still needs efforts of our fellows in surgery to conduct multi-centered prospective well-designed clinical study to
evaluate GNRI tools objectively.
