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: service: hepatobiliary surgery service history of present illness: the patient is a 64-year-old male with a history of ulcerative colitis for 15 years and primary sclerosing cholangitis for 12 years with a history of multiple biliary obstructions and abdominal pain with jaundice. the patient was referred to the initially endoscopic retrograde cholangiopancreatogram was performed and a stent was placed. the patient's bilirubin decreased from 8 to 1.2. the patient was then scheduled for placement of a percutaneous transhepatic cholangiogram drain and was referred to dr. for additional follow up. stent, but was unable to access the left biliary system. the patient was admitted for further work up at that time. the patient then presented to under the care of dr. on

surgical history: 1. status post endoscopic retrograde cholangiopancreatogram with stent placement multiple times. 2. status post right th biliary drain. 3. status post bilateral arthroscopic surgery on his knees. allergies: questionable allergy to penicillin. medications: 1. celebrex. 2. prilosec. 3. univasc. 4. sulfasalazine. 5. levoxyl. 6. ursodiol. social history: patient denies history of tobacco and alcohol use. initial physical examination: heart rate 103, blood pressure 121/55, respiratory rate 18, 95% on room air. in general is in no acute distress, normocephalic. head, eyes, ears,

rhythm, ii/vi murmur. gi: soft, nontender, nondistended, positive bowel sounds. extremities: palpable pulses. neurologic: grossly intact. hospital course: the patient was admitted and brought to the or with primary diagnosis of primary sclerosing cholangitis, right and left hepatic duct strictures. he had a left hepatic lobectomy with common duct excision, roux-en-y hepaticojejunostomy to the right hepatic duct. the patient tolerated the procedure well. required two units of pack red blood cells and cc of crystalloid. the patient was transferred to the icu in stable condition. the patient was initially admitted to the icu in stable condition. on postoperative day #2, the patient was out of bed to the chair and using his incentive spirometer. his drains were intact and his dressing was also intact. the ng tube put out roughly 60 cc. on the 27th, the patient continued to do well. he was up and walking around. ng tube was discontinued and the epidural was continued at 4 cc. on the 28th, the epidural and foley were discontinued. diet was advanced and dressings were changed. on the 29th the patient still continued with vancomycin and cipro which were continued from the or. he continued to do well with no major events. on the 30th it was decided that the patient would have an cholangiogram on at 11 am. for the remainder of the hospital stay, the patient was stable and ambulating well. the cholangiogram on the 2nd showed no leak. at that time it was decided the patient could be discharged home. discharge physical examination: t max 92.0 f, 78, 142/72, 18, 95% on room air, 470 p.o., 1320 out in urine. jp #1 75 cc. jp #2 30 cc. cardiovascular: regular rate and rhythm. respiratory: clear to auscultation bilaterally. abdomen: soft, nontender, nondistended. drains

m.d.,ph.d. 02-366 dictated by: medquist36 procedure: other cholangiogram anastomosis of hepatic duct to gastrointestinal tract lobectomy of liver other excision of common duct diagnoses: esophageal reflux unspecified essential hypertension unspecified acquired hypothyroidism percutaneous transluminal coronary angioplasty status ulcerative colitis, unspecified cholangitis obstruction of bile duct
