[Abstract]ob[x]jective To evaluate the value of dynamic detection of procalcitonin (PCT) in early diagnosis of infection after minimally invasive esophagectomy. Methods Sixty-eight patients as a observation group who underwent minimally invasive esophagectomy in department of cerebral surgery of Sun Yat-sen Memorial Hospital between June 2015 to June 2016 and 30 cases of normal physical examination as healthy group over the same period were enrolled in this retrospective study.PCT in blood of the patients undergoing surgery were detected on the first, second, third and fifth day after the surgery.Infection occurred in 10 patients out of the group, which were divided into an observation group and the others were divided into a control group. Differences of PCT among the three groups were statistically analyzed using SPSS 12.0 software package. Results On the first day after operation,PCT in the observation group and control group was higher than the healthy group, which showed statistical difference (P<0.05), but it has no statistical difference between observation group and control group. On the second day, the PCT of the observation group was higher than control group,which showed statistical difference (P<0.05). And on the third and the fifth day, the PCT of the observation group was higher significantly than control group, which showed statistical difference (P<0.01). Between the control group and healthy group, there was statistical difference on the first and second day after operation(P<0.05), but it has no statistical difference on the third and fifth day after operation. Conclusion A dynamic detection of PCT is value to the early diagnosis of infection after minimally invasive esophagectomy.When PCT is more than 2.06 p.g/ml on the second day after operation, the patient may be infected by bacteria. We should start the contrapuntal treatment as early as possible.

近几年随着食管癌微创技术的推广和普及,术后感染虽较前减少,但因食管为污染切口、患者多为高龄、且伤口疼痛、膈肌损伤导致患者不敢咳嗽咳痰等因素,术后发生感染率仍居高不下,目前仍是食管癌围手术期并发症死亡的主要原因之一[1]。大量研究[2,3]表明降钙素原( procalcitionin,PCT)能准确及敏捷地反映机体的细菌感染状态。而Castelli等[4]发现,PCT在外科手术、尤其是食管术后1—3天可因无菌性系统炎性反应综合征升高,但通常在2—3μg/mL,且会迅速降至正常;但Reith等[s]研究又提示,如在外科术后第1或第2天PCT值超过1.5μg/mL,则提示有继发感染的可能。这两个区间的交错重叠使得临床医生无法确定食管微创术后PCT为多高时应该立即启动治疗性的抗感染方案。我们试图通过研究68例食管癌微创术后PCT的动态值,找到一个敏感性和特异性均较满意的阈值,能提示临床医生尽早开始对食管癌微创术后的患者实施有针对性的抗感染治疗,则可能减少术后感染的死亡率,提高手术的疗效,改善患者的预后。
1资料与方法
1.1 研究对象及实验分组
研究对象为2015年6月至2016年6月我院胸外科收治的食管癌患者68例,有实施微创手术的适应症,无手术禁忌症。患者平均年龄62+2岁。术前行胸片、尿常规、血常规、大便常规等检查排除感染病灶。研究分组:拟实施食管癌微创手术患者68例为感染组,其中男42例,女26例;同期健康体检患者30例为健康组,平均年龄61+2岁,其中男19例,女11例:感染组和健康组年龄及性别比无统计学差异。分别检测实验组术后第1、2、3、5天的静脉血PCT值,其中10例发生感染,归为感染组,余58例为未感染组。
1.2观察时间及检测方法
患者实施食管癌微创手术治疗,手术方式均为胸腹腔镜联合食管胃部分切除、胸腹腔二野淋巴结清扫、食管胃颈部吻合。围手术期遵循我国2004年颁布的《抗菌药物临床应用指导原则》常规应用同一类抗菌药物预防感染治疗。在术后第1、2、3、5天分别采取静脉血3 mL送检。采用免疫层析法检测PCT。检测仪器为武汉明德生物科技股份有限公司的免疫定量分析仪,型号QMT8000。试剂盒为武汉明德生物科技股份有限公司的降钙素原检测试剂盒。
1.3统计学方法
所有统计数据均采用SPSS 12.0软件包统计分析各组别间的差异性。检测结果计量资料以均数±标准差表示,组间比较采用t检验,P<0.05为差异有统计学意义。

2.1三组PCT检测结果(表1)
术后第1天感染组、未感染组PCT较健康组升高(P<0.05),感染组和未感染组无统计学差异;术后第2天感染组较未感染组PCT显著升高(P<0.05),术后第3天及第5天感染组较未感染组PCT有显著升高(P<0.01);术后第1、2天未感染组PCT值较健康组显著升高(P<0.05);术后第3天和第5天未感染组和健康组相比无明显统计学差异。


3讨论

本研究为回顾性分析,研究对象为我院胸外科既往一年住院的食管癌微创术患者68例,样本数据较小。其原因为我院既往未能系统监测术后PCT数值或相关医生无意识通过监测PCT来更早地实施有效地抗感染治疗:未能满足术后连续检测PCT的患者被排除在外;另外,因传统开放性手术和微创手术术后PCT值已有统计学差异[6].某些病患因肿瘤过大或有局部的转移不适于行微创手术而需要行传统开胸手术被排除在外。系统误差的存在:2例感染患者在术后第3天出现高热以及明显的咳嗽咳痰,影像学资料提示肺部感染,已经开始针对性地抗感染治疗,而其他8例均在术后第5天后始出现相关感染症状(如胸痛、发热、咳嗽)或检查发现感染病灶(如肺部感染、泌尿系感染、胸腔感染)。但依据既往PCT与感染的正相关关系[1,2],假设患者全部在
