Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: brbpr major surgical or invasive procedure: colonoscopy history of present illness: hpi: 85f with htn, cad, pud, diverticulosis, hepatic cysts presents with two hours of brbpr associated with clots. she'd been in her normal state of health, feeling well when she developed rectal bleeding starting at 3pm on day of admission; it was her first episode ever, with no prior gi bleeds. she had a second episode at home, then came into the ed where she denied chest pain, dyspnea, abdominal pain, cramping, nausea/vomiting; she had experienced a few brief episodes of lightheadedness without syncope. in the ed, she was hemodynamically stable with a hematocrit of 32, near her baseline. she had an ng-lavage that was negative for both blood and clot. she passed two more bloody bowel movements and about an hour to two hours later dropped her systolic bp to the 80's, though this responded to ivf. her repeat hct at the time of the bm was 35, and a recheck 4hours later after ivf was down to 27, for which she was given one unit of prbcs. given her ongoing bleeding, the gi fellow recommended a tagged-rbc scan, that did not show evidence of bleeding at 90min. at the time of admission to the micu, she denied lightheadedness, chest pain, dyspnea, abdominal pain, n/v. her only complaint was of pain at the site of the ng-tube. past medical history: 1. hypothyroidism 2. h/o e. coli sepsis () 3. htn 4. h/o bronchitis 5. hepatic cystadenoma s/p resection () 6. cholangitis s/p
