目的 探讨术后早期应激性高血糖(SHG)对无2型糖尿病病史胃癌病人术后并发症的影响,并分析血糖峰值及SHG持续时间与预后的关系。方法 回顾性分析2022年1月至2024年3月苏北人民医院胃肠外科收治的行腹腔镜胃癌根治术的455例无2型糖尿病病史胃癌病人的临床资料。根据术后是否发生SHG分为SHG组(113例)和非SHG组(342例)。比较两组术后并发症发生率及严重程度,并采用多因素Logistic回归分析独立危险因素,同时对SHG病人按血糖峰值(≤14.0 mmol/L和>14.0 mmol/L)及持续时间(持续1 d、持续2 d、持续3 d)进行分层分析。结果 SHG组术后并发症发生率显著高于非SHG组(46.9% vs. 23.1%,P<0.001)。多因素分析结果显示,年龄(OR=2.262,P=0.002)、手术时间(OR=1.876,P=0.005)及SHG(OR=2.355,P=0.004)为术后并发症的独立危险因素。SHG组切口感染、肺部感染、肠梗阻及吻合口漏发生率显著增高(P<0.05)。进一步分析结果显示,血糖峰值≥14.0 mmol/L病人术后并发症风险增加(χ²=8.246,P=0.004),且Ⅲ级并发症发生率升高(χ²=5.262,P=0.022);在发生SHG的病人中,按SHG持续时间分层的术后并发症发生率差异有统计学意义(χ²=25.862,P<0.001)。结论 术后早期SHG是无2型糖尿病病史胃癌病人术后并发症的独立危险因素。重度高血糖及SHG持续时间延长导致并发症发生风险增高,故围手术期血糖管理应同时关注血糖水平和持续时间。
Objective To investigate the impact of early postoperative stress hyperglycemia (SHG) on postoperative complications in gastric cancer patients without a history of type 2 diabetes mellitus, and to analyze the associations of peak blood glucose level and SHG duration with prognosis. Methods A retrospective analysis was conducted on the clinical data of 455 gastric cancer patients without a history of type 2 diabetes mellitus who underwent laparoscopic radical gastrectomy at the Department of Gastrointestinal Surgery, Northern Jiangsu People’s Hospital, between January 2022 and March 2024. According to whether SHG occurred after surgery, the patients were divided into a SHG group (n=113) and a non-SHG group (n=342). The incidence and severity of postoperative complications were compared between the two groups, and multivariate logistic regression analysis was used to identify independent risk factors. In addition, SHG patients were stratified according to peak blood glucose level and duration of SHG for further analysis. Results The incidence of postoperative complications was significantly higher in the SHG group than in the non-SHG group (46.9% vs. 23.1%, P<0.001). Multivariate analysis showed that age (OR=2.262, P=0.002), operation time (OR=1.876, P=0.005), and SHG (OR=2.355, P=0.004) were independent risk factors for postoperative complications. The incidences of incision infection, pulmonary infection, intestinal obstruction, and anastomotic leakage were significantly higher in the SHG group (P<0.05). Further analysis showed that patients with peak blood glucose ≥14.0 mmol/L had a higher risk of postoperative complications (χ²=8.246, P=0.004) and a higher incidence of grade III complications (χ²=5.262, P=0.022). Among patients with SHG, the incidence of postoperative complications differed significantly among groups with different SHG durations (χ²=25.862, P<0.001). Conclusion Early postoperative SHG is an independent risk factor for postoperative complications in gastric cancer patients without a history of type 2 diabetes mellitus. Severe hyperglycemia and prolonged SHG duration are associated with an increased risk of complications. Therefore, perioperative blood glucose management should focus on both glucose level and duration.
