RESUMO
BACKGROUND: This study aimed to determine whether an abdominal radiograph 8 hours after ingesting oral Telebrix Gastro is a reliable marker for non-operative management in patients with adhesive small bowel obstruction. METHODS: During a 5-year period (January 1, 1995, through December 31, 2000), 97 patients were admitted for small bowel occlusion due to adhesion with no indication for immediate surgery. All received 100 mL of Telebrix Gastro via gastric tube for small bowel obstruction due to adhesion. If the contrast reached the colon within 8 hours on plain abdominal radiograph, the test was considered to be negative. RESULTS: 126 cases of small bowel occlusions were analyzed due to recurring episodes for 11 patients. The test was negative in 113 cases (89.7%), and in this group, only two patients underwent surgery, the remaining being managed non-operatively. The 13 cases (10.3%) with a positive test for occlusion underwent surgery. The sensitivity, specificity and accuracy of the finding of contrast media reaching the colon as an indicator for conservative treatment were 98%, 100%, and 98%, respectively. CONCLUSIONS: A water-soluble contrast study can be of significant help in the clinical management of patients suspected of having small bowel obstruction.
