[Gastrografin for mechanical partial, small bowel obstruction due to adhesions]

The therapeutic effect of gastrografin is occasionally mentioned in the literature. However, this effect has not been objectively evaluated. We studied prospectively the effect of Gastrografin in cases of adhesive, simple, partial, small bowel obstruction (SBO) compared to conventional management. During 3 years, a total of 137 episodes of simple, partial SBO in 127 patients (10 recurrent episodes) were treated. The episodes were randomized into a control group (80 episodes), treated conventionally, and a trial group (77 episodes), which received in addition 100 ml of Gastrografin administered through the nasogastric tube. The two groups were well-matched with regard to age, gender, weight, medical and surgical background and duration of complaints before admission. Time to first stool and resolution of obstruction, complications, need for surgery, and hospital stay were noted. Mean time to first stool was significantly shorter in the trial group: 6.2 +/- 3.9 hours vs 23.5 +/- 12.7 (p < .0001). Mean hospital stay for unoperated patients was also shorter in the trial group: 2.7 +/- 2 days vs 5.5 +/- 2 days, (p < .0001). In addition, significantly fewer episodes in the trial group required operation, 10.4 vs 26.7% (p < 0.013). 1 patient in each group dies following operation. There were no Gastrografin-related complications and it was effective and safe for adhesive, partial, simple SBO. It significantly speeds resolution of obstruction, reduces the need for operation, and shortens convalescence.
