to be nontoxic and with no pertinent positives on physical examination. he was admitted to the medical service and evaluated for his anemia. he had a cta that was done that illustrated no evidence of any mass, a question of a duodenal diverticulum on the cta. colonoscopy illustrated diverticulosis of the sigmoid, and upper egd illustrated esophagitis and mild hiatal hernia in the gastric antrum. his egd on the 25th illustrated a mild hiatal hernia and an ulcer in the distal bulb. the colonoscopy done on the same day, on the 25th, also illustrated diverticulosis of the sigmoid colon, but otherwise a normal colonoscopy. this gentleman had a repeat egd done on the 27th. upon examination, when they entered the duodenal bulb, a large, organized, maroon colored clot was seen, and a single acute ulcerated ulcer measuring 2.5 cm was seen, and in that base were two visible vessels, which were clipped during the procedure. the patient was transfused during this admission. during this

began to be evaluated by physical therapy. the patient underwent a water soluble contrast study on the fourth to evaluate for closure of the duodenum which was intact. the patient had an echocardiogram done on the fourth to evaluate further pericarditis, which appeared to resolve. he had an ejection fraction of 55 on the echocardiogram, with some noted mild dilation of the left atrium as well as some mildly thickened mitral valve leaflets. as mentioned previously, his gastroduodenal anastomosis was without any evidence of contrast extravasation. the antibiotics levofloxacin and flagyl were discontinued on postoperative day seven, . the patient advanced to a regular diet after admitting to passing flatus. his tpn was stopped on the seventh, and the patient was encouraged to
