Role of Multidetector Computed Tomography in Bowel Obstruction
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 5
Abstract
Introduction: Intestinal obstruction accounts for 20% of surgical admissions of patients with acute abdomen. The early diagnosis of bowel obstruction is critical in preventing complications, particularly perforation and ischemia. Mechanical large bowel obstruction is 4-5 times less common than small bowel obstruction, most common cause being neoplasm. Materials and Methods: This is a hospital-based cross-sectional study (observational study) done on 53 patients, suspected to have intestinal obstruction referred for computed tomography (CT) scan of the abdomen to the Department of Radio Diagnosis at Saifee Hospital, Mumbai. The study period was 2 years (July 2013-June 2015). Results: This study comprised of 53 cases with suspicion of intestinal obstruction. The age group of patients ranged from 1 to 83 years with a mean of 49.2 years. Out of 53 cases, 26 cases were males (49.06%) and 27 were females (50.94%). Abdominal distention and inability to pass stools were most common symptoms in the study. Overall performance of CT in diagnosis of intestinal obstruction consisted of 75% true positive cases, 14.58% true negative cases, 8.33% false positive cases, and 2.08% cases of false negative. Thus, on statistical analysis (McNemar’s Chi-square test) CT was found to be 97.29% sensitive and 63.63% specific in diagnosis of intestinal obstruction. Conclusion: CT has become the most important non-invasive imaging tool to diagnose small and large bowel diseases as it has the potential to provide significant information which leads to timely appropriate treatment and thus positively affect the outcome, morbidity, and mortality of patients.
