Evaluate serum procalcitonin (PCT) level as a predictor of intestinal ischemia or necrosis (IN) in patients with postoperative adhesive small bowel obstruction (ASBO).
Prospective cohort of consecutive patients with ASBO. Patients previously treated with antibiotics or septic were excluded. PCT was measured at the diagnosis of ASBO and every 24 h afterwards.
intestinal ischemia or necrosis (IN).
Fifty-nine patients were included, 12 of whom were excluded; 47 patients remained in the study; male-to-female ratio = 1.9:1.
medical in 15 cases (32%) and surgical in 32 (68%).
Intestinal necrosis (IN) in 10 patients (21.3%). Mean PCT level was higher in patients with IN (15.11 ng/ml vs. 0.183 ng/ml, p=0.002), the proportion of patients with elevated PCT (>0.5 ng/dl) was higher in patients with IN (70% vs. 8.1%, p=<0.001, RR=26.4 with a 95% CI of 4.39-159.5). Elevated PCT levels at diagnosis had a 70% positive predictive value (PPV) and 91.8% negative predictive value (NPV) for prediction of IN. With a PCT value at diagnosis of >1.0 ng/dl, PPV was 87.5% and NPV, 92.3%.
PCT levels are closely related to the presence of intestinal ischemia and necrosis in children with ASBO.
Study of Diagnostic Test, Level II.
评估血清降钙素原（PCT）水平作为术后粘连性小肠梗阻（ASBO）患者肠缺血或坏死（IN）的预测指标。
对连续性ASBO患者进行前瞻性队列研究。排除既往接受过抗生素治疗或患有败血症的患者。在ASBO诊断时及之后每24小时测量PCT。
肠缺血或坏死（IN）。
纳入59例患者，其中12例被排除；47例患者继续参与研究；男女比例为1.9:1。
15例（32%）采用内科治疗，32例（68%）采用外科治疗。
10例患者（21.3%）发生肠坏死（IN）。IN患者的平均PCT水平更高（15.11 ng/ml对0.183 ng/ml，p = 0.002），IN患者中PCT升高（>0.5 ng/dl）的比例更高（70%对8.1%，p<0.001，RR = 26.4，95%CI为4.39 - 159.5）。诊断时PCT水平升高对IN的预测阳性预测值（PPV）为70%，阴性预测值（NPV）为91.8%。诊断时PCT值>1.0 ng/dl，PPV为87.5%，NPV为92.3%。
PCT水平与ASBO患儿肠缺血和坏死的发生密切相关。
诊断性试验研究，二级。
