PURPOSE: The objective was to develop a radiological score obtained from multi-detector computed tomography (MDCT) to differentiate between single band adhesion (SBA) and matted adhesions (MA) as the etiology of small bowel obstruction (SBO).
METHODS: All consecutive patients who underwent surgery from January 2013 to June 2018 for adhesion-induced SBO were retrospectively included.
RESULTS: Among the 193 patients having surgery for SBO, 119 (61.6%) had SBA and 74 (38.4%) had MA surgically proven. In multivariate analysis, the presence of a beak sign (OR = 3.47, CI [1.26; 9.53], p = 0.02), a closed loop (OR = 11.37, CI [1.84; 70.39], p = 0.009), focal mesenteric haziness (OR = 3.71, CI [1.33; 10.34], p = 0.01) and focal and diffuse peritoneal fluid (OR = 4.30, CI [1.45; 12.73], p = 0.009 and OR = 6.34, CI [1.77; 22.59], p = 0.004, respectively) were significantly associated with SBA. Conversely, the presence of diffuse mesenteric fluid without focal fluid (OR = 0.23, CI [0.06; 0.92], p = 0.04) and an increase of the diameter of the most dilated loop (OR = 0.94, CI [0.90; 0.99], p = 0.02) were inversely associated with SBA. Using the significant predictive factors of SBA, we built a composite score to radiologically predict the etiology of SBO. The area under the receiver operating characteristic (ROC) curve of the score was 0.8274. For a cut-off score of -0.523, sensitivity, specificity and the percentage of patients correctly classified were 78.4%, 84.6% and 80%, respectively. If the score is ≥ 7, the probability that the mechanism of SBO is not SBA was 100%.
CONCLUSIONS: The present score, validated in a different population, could be a significant tool in the decision for surgical management.
