| Methods |
Randimised clinical trial |
| Participants |
Patients with symptoms and signs of small bowel obstruction who had previous abdominal surgery and presumed to have adhesive small bowel obstruction. |
| Interventions |
Patients were randomised for gastrografin orally, they were given 100 ml of gastrografin via a nasogastric tube, a radiograph was obtained after 24 hours. and a control group who were treated with intravenous rehydration and nasogastric suction. The gastografin group was further divided into those in whom the contrast was seen in the colon after 24 hours or not. |
| Outcomes |
The need for surgical intervention and length of hospital stay was compared between the two groups. In the Gastrografin group the arrival of the contrast to the colon after 24 hours was corelated with the success of the conservative treatment. |
| Notes |
Gastrografin group is suitable for analysis in the diagnosis arm ot the review. The entire study patients are suitable for the treatment analysis. |
