Abstract
AIM: To improve the preoperative diagnosis of mechanical intestinal obstruction.
METHODS: The clinical data for 127 patients with mechanical intestinal obstruction confirmed by laparotomy and pathological examination were retrospectively analyzed. The diagnostic value of abdominal plain film, ultrasonography and CT in assessing the presence of intestinal obstruction and strangulation or not, obstruction site and etiology was comparatively analyzed.
RESULTS: The accuracy of CT in assessing the presence of intestinal obstruction, obstruction site and etiology were 97.4%, 98.7% and 75.6%, respectively, significantly higher than that of abdominal plain film and ultrasonography (all P < 0.05). The incidence of free fluid detected by ultrasonography was significantly higher in patients with strangulated intestinal obstruction than in those with non-strangulated disease (87.1% vs 45.2%, P < 0.05).
CONCLUSION: CT has higher diagnostic accuracy than abdominal plain film and ultrasonography in assessing the presence of intestinal obstruction or not, obstruction site and etiology. When free fluid is detected by ultrasonography in patients with small bowel obstruction, strangulation should be considered.
