DCR: CT肠造影指数对克罗恩病患者术后腹腔感染并发症的预测价值

2021-08-26 MedSci原创 MedSci原创

克罗恩病 (CD) 是一种慢性反复发作的胃肠道疾病,目前对于它的发病原因还知之甚少。虽然目前许多医疗工作者正在以改善 CD 患者的预后和生活质量作为治疗目标。

      克罗恩病 (CD) 是一种慢性反复发作的胃肠道疾病,目前对于它的发病原因还知之甚少。虽然目前许多医疗工作者正在以改善 CD 患者的预后和生活质量作为治疗目标,但目前大多数 CD 患者在一生中仍需要至少接受一次手术治疗。此外,CD患者与结直肠癌患者相比,进行手术切除后的术后并发症发病率更高,CD患者会出现严重的并发症,包括营养不良、肠梗阻、腹腔内脓肿和全身感染等。尤其是腹腔内脓毒症并发症 (IASC) 的发生率增加显著,克罗恩病患者进行肠切除和吻合术的术后腹腔内脓毒症并发症频繁且难以处理。因此,本研究旨在探讨术前 CT 小肠造影在预测腹腔内脓毒症并发症方面的价值。

 

      这是一项回顾性和前瞻性观察性研究,研究人员招募了接受首次肠切除术的克罗恩病患者。使用CT 肠造影计算腹腔病变严重指数,并通过多变量分析评估其预测腹腔内脓毒症并发症的能力。然后进行了一项前瞻性研究以评估该 CT 肠造影指数的可靠性。

 

      研究结果初步显示接受一期手术的患者术后腹腔内脓毒症并发症的发生率显着高于接受二期手术的患者(3/103 vs 24/241;2.9% vs 10.0%;p = 0.026)。多变量分析确定了 5 个 CT 肠造影参数,包括肠系膜纤维脂肪增生、腹腔内脓肿、肠瘘、腹腔积液和肠管扩张狭窄,是腹腔内脓毒症并发症的独立预测因子(p < 0.001)。构建了基于这 5 个参数的列线图模型。ROC曲线下面积显示 CT 肠造影列线图评分截止值为 175 时其作为预测因子腹腔内脓毒症并发症的敏感性为 83.3%,特异性为 85.3%。在前瞻性研究中,那些 CT 肠造影列线图评分 >175 的患者被分配到 2 期治疗组,这些患者腹腔内脓毒症并发症发生率出现了明显的下降。

 

      本项研究证实术前 CT 小肠造影结果可预测术后结果并有助于确定克罗恩病的手术方法。CT 肠造影证实腹腔内检查结果较差的患者可能受益于肠切除术后造口的建立。
