patient admitted to thoracic surgery service and underwent transhiatal esophagectomy on which proceeded without any complications. he was placed in the cardiac surgery recovery unit in the immediate postoperative period and was extubated without difficulty. he remained nil per os until tube fees were started at 30ml per hour on postoperative day number three which he tolerated well. he then began to pass flatus on postoperative day number six at which point his tube feeds were advanced to goal. he was then given a trial of grape juice to assess for an anastomotic leak and there was no grape juice noted in the neck drain. thus he was given clears which by the time of discharge were advanced to full liquids as tolerated which he has done well with. his other issue during the postoperative period involved a likely supraventricular tachycardia and cardiology was involved. they ascribed this to likely atrial fibrillation and he was discharged on diltiazem 90mg four times a day, and metoprolol 50mg . he was on a diltiazem drip off and on for three days prior to discharge however this was able to be weaned and he was placed on oral medications only with his heart rate well
