Abstract:
Objective To explore the predictive value of different CT signs in surgical treatment in patients with acute closed intestinal and mesenteric injury.Methods The CT data and follow-up results of 120 patients with acute closed intestinal and mesenteric injury(including 58 cases of surgical treatment and 62 cases of conservative treatment)were analyzed retrospectively.The diagnostic value and prognostic value in surgical treatment of different CT signs were analyzed.Results There were significant differences between the operation group and the conservative treatment group in mesenteric vascular amputation,mesenteric hematoma,vascular contrast agent extravasation, intestinal wall defect,pneumoperitoneum and peritoneal effusion (χ2=4.69,P=0.03;χ2=21.40,P<0.001;χ2=13.95,P<0.001 ;χ2=11.34,P=0.001;χ2=80.65,P<0.001).The CT signs of intraperitoneal effusion had the highest sensitivity for intestinal and mesenteric injury,and vascular contrast agent extravasation and intestinal wall defect had the highest specificity for surgical predictability of intestinal and mesenteric injury.ROC curves showed that abdominal gas accumulation had the highest predictive value for intestinal and mesenteric injuries (AUC=0.92,95%CI:0.87-0.97),followed by mesenteric hematoma (AUC=0.73,95%CI:0.64-0.82).Conclusion Intraperitoneal effusion has the highest sensitivity for intestinal and mesenteric inj ury,and vascular contrast agent extravasation and intestinal wall defect have the highest specificity for surgical predictability of intestinal and mesenteric injury.The overall value of intraperitoneal gas in predicting intestinal and mesenteric injury is highest.Combining different CT signs can improve the accuracy of clinical intervention for acute closed intestinal and mesenteric injury.
