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: mr. is a 59-year-old man with a history of colon cancer that now presents with a sigmoid colectomy in for a t3-n0 grade 2 adenocarcinoma of the colon. since that time he has had a recent rise in his cea. recent ct scan of the chest, abdomen and pelvis in demonstrated a 2 mm nodule in the left lower lobe of the lung that was unchanged from previous ct's in both and in . however, the abdominal ct demonstrated ill defined low attenuation mass near the porta he is now referred for caudate lobe resection. past medical history: significant for the following: adenocarcinoma of the colon as described above. adult onset diabetes mellitus. hypertension. hypercholesterolemia. status post sigmoid colectomy. allergies: eggs. medications: lipitor 10 mg po q day, glucophage 1000 mg po q day, zestril 8 mg po q day, aspirin 81 mg po q day, nortriptyline 10 mg po q day, vitamin e 400 iu po q day, centrum silver po q day. physical examination: his blood pressure was 146/76, heart rate 88, temperature afebrile and weight 186 lbs. in general he is well developed and a well nourished male in no acute distress. his skin is normal. his head, eyes, ears, nose and throat demonstrates no scleral icterus. his oropharynx was clear. neck was supple without lymphadenopathy or thyromegaly. his carotids are 2+ and 4+ without bruit. his lungs are clear to auscultation bilaterally. heart has a regular rate and rhythm with a normal s1 and s2. there is no murmur, rub or gallop. abdomen demonstrates a well healed low midline incision, there is no hepatosplenomegaly, masses, tenderness or incisional hernia. his extremities are without peripheral edema and neurologically he is grossly intact. laboratory data: in sodium 138, potassium 5.2, chloride 99, co2 25, bun 18, creatinine 0.8, glucose 189, calcium 9.5, ast 30, alt 41, alkaline phosphatase 71, total bilirubin 0.5 and albumin 4.2. hospital course: the patient was admitted to the general surgery service and on was taken to the operating room. there, he had a right hepatic lobectomy, cholecystectomy, wedge biopsy of the left lobe, needle biopsy of the left lobe and intraoperative ultrasound. during his operation he was transfused with one unit of packed red blood cells. postoperatively he was taken to the surgical intensive care unit where he was extubated on the evening of his operation. the remainder of his hospitalization is dictated by systems. 1. neurologic: the patient had pain control with an epidural that contained both dilaudid and bupivacaine. he did not receive total analgesia with this and because of his discomfort on postoperative day #1, the acute pain service bolused his epidural while he was still in the surgical intensive care unit. he became markedly hypotensive with this and required several hours of vasopressive support with a neo-synephrine drip. subsequent to this time, his epidural was no longer used, he started to take po and he was maintained with oral percocet. his epidural catheter was discontinued without incident on the second postoperative day and patient continued to receive adequate analgesia with oral percocet throughout the remainder of his hospitalization. 2. cardiopulmonary: other than the episode of hypotension that he experienced from his epidural, the patient had no other acute cardiopulmonary events. he was stable on the floor for several days and his zestril was restarted prior to his discharge. his aspirin continued to be held at the time of his discharge and will need to be restarted once the patient follows up as an outpatient. he had access with a right internal jugular central venous line that was kept in place until the date of his discharge. it was discontinued without incident prior to his leaving. 3. gi: on the evening of his operation, the patient's transaminases were markedly elevated as we expected them to be with an alt of 2,220 and an ast of . the following day these had decreased to an alt of 1822 and an ast of 1439, however, because these were not decreasing as quickly as we expected them to, the patient had an ultrasound of his liver. the study was limited but the hepatic artery, hepatic vein and portal vein were felt to demonstrate adequate blood flow. throughout the remainder of the patient's hospitalization, his liver enzymes continued to trend downward. by the date of the patient's discharge his alt had decreased to 431 and his ast was 97. his alkaline phosphatase had consistently remained in the 60-100 range and his total bilirubin was steady at 1.7. he did have drains that had been placed intraoperatively with the medial drain placed inferior to the liver and the lateral drain placed adjacent to his liver. these continued to put out several hundred cc per day and the patient was discharged home with both of them in place. he was educated as to their care and maintenance and instructed to measure the output and consistency of the drains. 4. fluids, electrolytes & nutrition: the patient was started on po on the afternoon of his first postoperative day and by the following day was tolerating percocet without any problems. his diet was subsequently advanced on the third postoperative day and his glucophage was restarted. the patient continued to tolerate a regular diet up until the time of his discharge. he did require some sliding scale insulin. during this time his blood sugars remained in the 180-200 range which we felt were acceptable in the acutely postoperative patient. for the entire hospitalization he also received intravenous zantac for stress ulcer prophylaxis. he was not discharged home on this. 5. infectious disease: the patient received intravenous unasyn during his operation and for the first two postoperative days. subsequent to this time it was discontinued. the patient did continue to have problems with fever during his postoperative course. on the third postoperative day he had a maximum temperature of 102 degrees. he was pancultured for this and all studies proved to be negative. it was ultimately felt that his fever was atelectatic as he had diminished breath sounds in his right base and was limited by pain on taking a deep breath. the patient was not discharged home on any antibiotic therapy. surgical pathology of his intraoperative specimen revealed that he had a normal gallbladder with two lymph nodes demonstrating no evidence of malignancy. in addition, he had a liver needle biopsy that demonstrated macro and micro vesicular steatosis with no evidence of malignancy. his wedge biopsy demonstrated a bile duct adenoma and his resected portion of liver demonstrated adenocarcinoma that was moderately differentiated, consistent with a colorectal primary. the margins of this were 2 mm from the ink resection margin and there is no vascular invasion seen. on the patient was discharged home in stable condition in the care of his family. he had drains in place and was instructed in proper care for them at home. discharge medications: he was discharged home on the following medications: lipitor 10 mg po q day, glucophage 1,000 mg po q day, zestril 5 mg po q day, multivitamin, vitamin e, nortriptyline 10 mg po q day, percocet po q 4-6 hours prn. the patient was not restarted on aspirin. as stated above, this needs to be restarted upon follow-up. the patient verbalized understanding of all of his discharge instructions and was told to follow-up with dr. in approximately one week. discharge diagnosis: 1. metastatic colonic adenocarcinoma, now status post right hepatic lobectomy. , m.d.,ph.d. 02-366 dictated by: medquist36 procedure: venous catheterization, not elsewhere classified closed (percutaneous) [needle] biopsy of liver cholecystectomy open biopsy of liver lobectomy of liver diagnoses: pure hypercholesterolemia malignant neoplasm of liver, secondary unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled personal history of malignant neoplasm of large intestine other chronic nonalcoholic liver disease
