| Methods |
A prospective randomised controlled trial |
| Participants |
Patients with adhesive small bowel obstruction.
Patients with strangulation, primary small bowel obstruction, inflammatory bowel disease, and patients with hernia were excluded. |
| Interventions |
Trial group given 100 ml of gastrografin via nasogastric tube and the tube was clamped for 2‐3 hours. Both the trial and the control groups were treated with intravenous rehydration, abdominal x ray was taken after 6 hours, and all were clinically monitored. |
| Outcomes |
Resolution of the obstruction or the need for surgical intervention were compared in both groups as well as hospital stay. |
| Notes |
They excluded patients in whom no gas was seen in the colon on plain films that was taken on admission (ie patients with complete small bowel obstruction). |
