Abstract    Objective    To evaluate the estimation of physiologic ability and surgical stress (E-PASS) for predicting postoperative complication in elective stomach neoplasms surgery. Methods    The clinical data of 121 cases of elective stomach neoplasms surgery performed between November 2011 and February 2012 in Department of Gastrointestinal Surgery, West China Hospital, Sichuan University were collected after the research question was developed. The clinical-surgical-pathological parameters were compared between complication group and non-complication group. The cutting point of CRS for predicting postoperative  complications was analyzed. Results    In 121 cases, the incidence of postoperative complications is 14.9%. The differences of age, sex, tumor histologic types, diabetes, performance status index, ASA grade, extent of skin incision, blood loss-body weight ratio, blood loss, body weight, operation time, PRS and SSS between complication group and non-complication group were not significant statistically. Severe heart disease (P=0.000) and severe pulmonary disease (P=0.000) between the two groups have significant difference statistically. The CRS of complication group was higher than that of non-complication group (P=0.043). But the cutting point of CRS for predicting postoperative complications was not elicited (r＜0.400，P＞0.05). Conclusion    CRS of the E-PASS scoring system has some value for predicting the risk of elective stomach neoplasms surgery. But the alerting cutting point of CRS still needs further investigation.
