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.

Inclusion Criteria:

• Patients undergoing small bowel resection. Can be elective, urgent or emergent.

Exclusion Criteria:

• Patient with atrial fibrillation who is considered a non-coffee drinker (drinks coffee less than 3 days per week over the last 4 weeks)
• Patients undergoing colon resection without removal of any portion of small bowel.

There is no plan to share individual patient data at this time.

Patients will not be told what group they are assigned to, however, complete masking will be difficult to achieve. The patient's treatment assignment is part of the medical record.
