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: history of present illness: this is an 89-year-old male with a history of chronic epigastric pain with a 2-day history of nausea, vomiting, and diarrhea. the patient denied any fevers or chills. the patient has had gastroesophageal reflux disease symptoms with epigastric pain. he had no hematuria, no melena, and no bright red blood per rectum. he denied any recent blood loss. past medical history: 1. atrial fibrillation. 2. gastroesophageal reflux disease. medications on admission: coumadin 6 mg alternating with 7.5 mg, zestril p.o. q.d., maalox as needed, zantac 150 mg p.o. b.i.d., celexa 20 mg p.o. q.d. allergies: penicillin. social history: no alcohol or tobacco. physical examination on presentation: physical examination revealed temperature was 98.9, heart rate was 89, blood pressure was 130/70, respiratory rate was 15, oxygen saturation was 96% on room air. in general, in no acute distress. head, eyes, ears, nose, and throat revealed sclerae were anicteric. cardiovascular was irregular. lungs were clear to auscultation. abdomen was soft, mildly distended, and nontender. no masses, and no scars seen. rectal was heme-positive with no masses. extremities revealed no edema. neurologically, he was grossly intact. pertinent laboratory data on presentation: laboratory data on admission revealed his sodium was 143, his potassium was 4.3, chloride was 101, bicarbonate was 32, blood urea nitrogen was 28, creatinine was 1.2, and blood glucose was 156. his white blood cell count was 12.3, hematocrit was 41, platelets were 194. his bilirubin was 0.7, alkaline phosphatase was 66, alt was 25, ast was 19, amylase was 47. his inr was 2. radiology/imaging: a ct scan was done which revealed obstruction at the splenic flexure. hospital course: the patient was admitted and made nothing by mouth and started on some antibiotics; namely, ciprofloxacin and flagyl. he was admitted to the medicine service. it was decided that a colonoscopy should be performed. due to the evaluated inr, several days were waited prior to doing the colonoscopy due to the risk of hemorrhage during biopsy. it was attempted to give the patient fresh frozen plasma; however, he became anaphylactic. the patient eventually had a colonoscopy and biopsies taken. the biopsies revealed adenocarcinoma. careful review of the ct scan showed a low attenuation and lesion in the tail of the pancreas associated with a splenic flexure mass. after very extensive discussions with the family, it was initially decided the patient should not have surgery. however, the family then wished to have surgery. a preoperative stress mibi was obtained. the results were an ejection fraction of 49% with a small inferior reversible defect. the patient was brought to the operating room on . the procedure performed was an exploratory laparotomy with mobilization of the spleen and colocolotomy. postoperatively, the patient was transferred to the floor for his care. on postoperative day one, it was noted the patient was not making adequate amounts of urine. despite receiving multiple fluid boluses, the patient's urine did not respond. the patient was transferred to the intensive care unit, and a swan-ganz catheter was placed. based upon his numbers, the patient was started on dopamine at high doses. the patient began to make urine. the creatinine value for the patient also increased from a baseline of 0.8 to a value of 1.8 on postoperative day one, and eventually to a value of 3. the patient remained in the intensive care unit intubated and on dopamine. eventually, the dopamine was weaned, and the patient was started on levophed. on postoperative day two, a troponin value was obtained which was 19. a cardiology consultation was obtained, and it was decided catheterization would not be performed at that time. on the night of , the patient had an episode of emesis with a high suspicion for aspiration. the patient's oxygenation significantly worsened. an extensive discussion was started with the family on and continued into . it was decided on , that support should be withdrawn. the patient expired in the afternoon of . discharge diagnoses: 1. status post colocolotomy. 2. transferred to the intensive care unit. . death. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified venous catheterization, not elsewhere classified other endoscopy of small intestine insertion of endotracheal tube laparoscopy suture of laceration of large intestine pulmonary artery wedge monitoring closed [endoscopic] biopsy of large intestine large-to-large intestinal anastomosis transfusion of other serum diagnoses: subendocardial infarction, initial episode of care congestive heart failure, unspecified acute kidney failure, unspecified cardiac complications, not elsewhere classified atrial fibrillation acute respiratory failure urinary complications, not elsewhere classified unspecified intestinal obstruction malignant neoplasm of splenic flexure 

Answer: The patient is high likely exposed to
