Despite ultrasound serving a great deal as an accurate tool in diagnosing intussusception, evidences on the diagnostic accuracy of absent colour flow with the intraoperative finding are limited. The aim of the study was to assess the diagnostic accuracy of absent flow on colour Doppler Ultrasound study with intraoperative findings of Intussusception Methods: Hospital based retrospective crossectional study was used. The medical record number of patients operated in the past 5 years, from September 2017-December 2022, with the preoperative diagnosis of intussusception, was traced and their charts were retrieved. The data was collected with standardised questionnaire. The data was cleaned, entered and analyzed using SPSS version 25. Diagnostic accuracy of absent color flow to predict gangrenous and viable bowel was measured using Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). Uni-variate analysis was performed to test factors associated with gangrenous intussusception. A binary logistic regression mode was used to identify independent risk factors. Results of logistic regression reported as adjusted odds rations (OR) with 90% confidence intervals. Results: During this crossectional study, data from 121 patients were collected. The median age was 9 months (±IQR 9) with male predominance (70.2%). The most common complaints were vomiting (93.4%), non-bloody Diarrhea (78.5%), abdominal pain (89.3%), fever (29.7%), abdominal distension (14%) and, bloody diarrhea (8.3%). while the commonest physical findings were currant jelly stool detected at the time of DRE (62.8%), palpable abdominal mass (45.5%), abdominal distension (41.3%). Classic triads were present in 35.5% of the patients. The postoperative complication rate was 20.7% and mortality rate was 2.5%. Conclusion: In our setting Color Doppler US had Sensitivity of 46.8%, Specificity of 84.3%, PPV of 66.67% and NPV of 70.2% in predicting whether or not an intussuscepted bowel is gangrenous.en-USPaediatric gangrenous IntussusceptionOutcomeDoppler USThesis
