Post-operative ileus ("post-op ileus") is a condition which can occur after surgery. This means that the bowels stop working correctly and food and liquids will not pass through in the normal manner. Post-op ileus can be uncomfortable and require a longer hospital stay until the bowels begin to function correctly again. Currently there are no effective methods for preventing post-op ileus. Some studies suggest there is a benefit from drinking coffee following colon or gynecological cancer surgeries with very little risk. However, the effects of coffee following small bowel surgery have not been studied. This randomized, controlled trial will compare the outcomes of patients who receive coffee during their hospital stay after small bowel surgery to similar patients who receive warm water. About 60 patients will be in each group. The main outcomes are time until the nasogastric tube is removed and length of hospital stay.
