Abstract

Introduction: Bowelobstruction is the most common health event amid all surgical admissions for acute abdominal pain. Small intestinal obstruction is responsible for around 12–16% of admissions in surgicalemergencies and around 20% of procedures from emergency surgeries. Methodology: This was a cross-sectional analyticalstudy. The totalsample size was 142 and the non-probabilitypurposivesamplingtechniquewas used. Factors such as gender, age, and pathologies associated with intestinal obstruction were analyzed using descriptive statistics and a chi-square test. Furthermore, the diagnostic accuracy of MDCT in case of intestinal obstruction was evaluated by a 2 x 2 table. Results: Adhesions found on CT and surgery accounted for 8.5% and 13.4% respectively. Neoplasms were identified in 13.4% of cases on CT and 11.3% of cases during surgery. Hernias was discovered in 14.8% of cases on CT and 9.2% of cases in laparotomy. Ascites were found in 21.1% of cases on CT and 2.8% during surgery. Impacted stools were present in16.9% ofcases onbothCT and surgery. 2x2 table revealed intestinal obstruction, 52.1% on CT and 45.1% during surgery. Conclusion:Our findingsrevealedthatMDCTdemonstratedmoderatesensitivity(58.11%)and specificity (69.12%) in the identification of intestinal obstruction compared to surgical findings. The diagnosticaccuracyofMDCTis63.38%.
