At the time of diagnosis of postoperative ileus and after enrollment and randomization, all patients will be returned to NPO status. Nasogastric tubes (NGT) may be placed for gastric decompression at the discretion of the surgical team if clinically indicated. In the event that an NGT is placed, medications will be given orally or via the NGT, which will be clamped for 30 minutes after administration. Patients will continue on standard ERAS pathways with the exception of reduction of diet. Antiemetics will be given as clinically indicated; however, no prokinetic or promotility agents will be given as scheduled dosages.
