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: the patient is a 76-year-old retired firefighter with a past medical history significant for coronary artery disease, atrial fibrillation, and resected colon cancer who previously presented here on with feeling off, unmotivated, along with a bout of diarrhea. the patient stated that he had passed several light-colored stools and became very itchy at night to the point that he would scratch himself with his hand which began to bleed. the patient stated that he had a good appetite, but no motivation to eat. the patient was seen jaundiced when he originally presented to an outside hospital. the patient denied any fevers, chills, or chest pain. in summary, the workup included an endoscopic retrograde cholangiopancreatography and placement of a percutaneous transhepatic cholangiography at that time to drain the biliary tree. the patient tolerated the procedures well. a computed tomography of the liver showed a patent right middle and left hepatic veins and a patent superior mesenteric vein and main portal vein and an occluded right portal vein. the patient evidence of intrahepatic biliary ductal dilatation most prominent at segment four of the liver. focal atrophy was seen at this segment of the branch from the right portal veins, ............ segment was not visualized suggesting occlusion. there was no clear-cut mass identified, and the pathology report from the biliary brushings of the great hepatic mass were reported negative for malignant cells and ductoma unremarkable. the patient presented to have a resection of the liver mass. past medical history: (past medical history includes) 1. coronary artery disease (a) coronary artery bypass graft in . (b) myocardial infarction in . (c) atrial fibrillation. 2. insulin-dependent diabetes mellitus. 3. colon cancer. 4. hyperlipidemia. 5. hypertension. 6. gout. 7. microcytic anemia. 8. cataracts. 9. partial colectomy. 10. appendectomy. allergies: the patient has no known drug allergies. medications on admission: 1. gemfibrozil 600 mg by mouth twice per day. 2. zantac 150 mg by mouth twice per day. 3. furosemide 40 mg by mouth once per day. 4. amiodarone 100 mg by mouth every other day and 200 mg by mouth every other day. 5. regular insulin 40 units subcutaneous q.a.m. and 40 units subcutaneously q.p.m. 6. nph insulin 22 units subcutaneously in the morning and 22 units subcutaneously in the evening. 7. coumadin 5 mg by mouth once per day. social history: the patient smoked tobacco with a 20-pack-year history and occasional use of alcohol. physical examination on presentation: on the prior admission, the patient was afebrile with a temperature of 97.3, his blood pressure was 126/68, his heart rate was 72, respiratory rate was 18, and oxygen saturation was 92% on room air. the patient's weight was 99.4 kilograms. the patient was alert and oriented and in no apparent distress. head, eyes, ears, nose, and throat examination revealed sclerae were normal. pupils were equal, round, and reactive to light and accommodation. extraocular movements were intact. the mucous membranes were moist. no lymphadenopathy. no thyromegaly. chest examination revealed slight bibasilar crackles. cardiovascular examination revealed a 3/6 systolic ejection murmur with an irregularly irregular rate. abdominal examination revealed the abdomen was soft, nontender, and nondistended with drains in place. concise summary of hospital course: the patient was admitted to dr. service on . the patient underwent a cholecystectomy, with common bile duct excision, and roux-en-y hepaticojejunostomy with a diagnosis of cholangiocarcinoma. the patient was transferred to the surgical intensive care unit after the operation in stable condition. the patient was intubated on synchronized intermittent mandatory ventilation and was kept nothing by mouth. we continued to monitor the urine output with a insulin sliding-scale. the patient was treated with antibiotics after the operation. dictation incomplete: addendum dictated separately. , m.d.,ph.d. 02-366 dictated by: medquist36 procedure: venous catheterization, not elsewhere classified cholecystectomy other incision with drainage of skin and subcutaneous tissue other lysis of peritoneal adhesions pulmonary artery wedge monitoring anastomosis of hepatic duct to gastrointestinal tract excision of other bile duct diagnoses: unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled atrial fibrillation secondary malignant neoplasm of other specified sites calculus of gallbladder with other cholecystitis, without mention of obstruction peritoneal adhesions (postoperative) (postinfection) streptococcus infection in conditions classified elsewhere and of unspecified site, streptococcus, group d [enterococcus] malignant neoplasm of intrahepatic bile ducts infected postoperative seroma
