Sixty patients were randomized to one of two caffeine doses given three times a day, or a control group. There was no measurable effect from caffeine; time to first bowel movement was not improved: 68.2 h after caffeine versus 67.3 h in controls (P=0.887).

Comment; Well there goes the excuse to ask for a coffee after your operation.
