摘  要:目的评价结直肠癌术后腹腔引流液中C反应蛋白(CRP)水平的变化对早期发现吻合口瘘的诊断价值。方法天津市肿瘤医院结直肠肿瘤科于2015年7月至2016年1月期间,对术前明确诊断为结直肠癌并行结直肠癌根治术、术后病理证实肿瘤无残留、且手术前后均无感染的患者于术后1、2、3、4、5 d连续监测其腹腔引流液中的CRP水平,对比是否出现吻合口瘘患者CRP水平的差异,并绘制受试者工作特征(ROC)曲线评估腹腔引流液中CRP在对术后吻合口瘘的预测价值。结果172例患者入组,其中男性101例,女性71例;年龄(59.9 ± 10.3)岁。术后发生吻合口瘘24例(14.0%,吻合口瘘组),148例为非吻合口瘘组患者。除体质指数外,两组患者一般资料差异无统计学意义(均P 〉 0.05)。吻合口瘘组和非吻合口瘘两组患者腹腔引流液中CRP水平在术后1~4 d均呈上升趋势,但差异无统计学意义(均P 〉 0.05);第5天吻合口瘘组CRP水平呈持续上升趋势,而非吻合口瘘组CRP水平开始下降[(65.3 ± 38.9)g/L比(44.7 ± 39.5)g/L,t=-2.85,P= 0.005],差异有统计学意义。对吻合口瘘组患者进一步行分层分析,早期瘘(发生吻合口瘘时间术后〈10 d)CRP水平在术后1~5 d呈持续上升趋势,而晚期瘘(发生吻合口瘘时间术后〉10 d)CRP水平在术后1~4 d呈上升趋势,第5天略微下降,但与早期瘘组术后1~5 d的CRP检测水平比较,差异均无统计学意义(均P 〉 0.05)。将有无吻合口瘘作为状态变量,以CRP水平作为检测变量。第1~4天的曲线下面积分别为0.425,0.487,0.510和0.522;第5天的曲线下面积最大,为0.657(95%CI:0.537~0.777),约登指数最大为0.274;CRP的临界值为27.15,以此为切点预测出现吻合口瘘的灵敏度为87.5%,特异度为39.9%,阳性预测值为19.1%,阴性预测值为95.2%。结论结直肠癌术后1~5 d腹腔引流液�ObjectiveTo evaluate the diagnostic value of dynamic monitoring of C-reactive protein (CRP) in drainage fluid in predicting early anastomotic leakage after colorectal surgery.MethodsThis study enrolled 172 patients, who were diagnosed as colorectal cancer before operation and underwent radical surgery, without residual tumor tissues by postoperative pathology and perioperative infection, at the Tianjin Medical University Cancer Hospital between July 2015 and January 2016. The C-reactive (CRP) protein level in drainage fluid was continuously monitored from postoperative days (POD) 1 to 5. CRP level was compared between anastomotic leakage (AL) group and non-anastomotic leakage (NAL) group. Receiver operating characteristics (ROC) curve was used to estimate the value of monitoring CRP in drainage fluid to predict anastomotic leakage after colorectal surgery.ResultsAmong 172 patients, 101 cases were male and 71 cases were female, with age of (59.9 ± 10.3) years. Anastomotic leakage occurred after colorectal surgery in 24 cases (14.0%, AL group) and other 148 cases were defined as NAL group. Other than body mass index (BMI) , differences in baseline data were not statistically significant between two groups. The CRP lever in AL group and NAL group showed rising trend from POD1 to POD4[Day 1: (6.7 ± 8.4) g/L vs. (8.0 ± 10.6) g/L; Day 2: (24.8 ± 14.6) g/L vs. (28.3 ± 21.1) g/L, Day 3: (54.8 ± 26.5) g/L vs. (53.8 ± 27.6) g/L, Day 4: (62.0 ± 32.2) g/L vs. (58.4 ± 30.7) g/L], while the differences were not significant (all P 〉 0.05) . At POD 5, the CRP lever of AL group increased continuously, while that of NAL group decreased with significant difference[ (65.3 ± 38.9) g/L vs. (44.7 ± 39.5) g/L, t=-2.85, P= 0.005]. Further stratification analysis on AL group revealed CRP level in early AL (AL occurrence 〈 POD 10) showed rising trend from POD 1 to 5, while CRP level in late AL (AL occurrence 〉 POD 10) showed ris
