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. was recommended to dr. for evaluation of a rectal cancer. this rectal cancer was stage ii by ultrasound demonstrating carcinoma of the rectum starting at the cutaneous junction extending up 4 cm to 5 cm going into the muscularis propria. prior to surgery, the patient was seen by the stoma therapist and two sites had been marked for possible colostomy. the patient was scheduled for an operation on for direct admission to the hospital. past medical history: (the patient's past medical history includes a history of) 1. coronary artery disease, status post coronary artery bypass graft and followed by percutaneous transluminal coronary angioplasty. the patient has no following symptoms since this procedure. 2. gout. 3. degenerative joint disease. 4. peripheral vascular disease. 5. hypertension. 6. severe burns on both arms, when the patient was 18 months old requiring multiple skin grafts and amputation of his right fifth digit. 7. status post cerebrovascular accident. allergies: no known drug allergies. medications on admission: zestril 10 mg p.o. q.d., allopurinol 300 mg p.o. q.d., magnesium oxide 400 mg p.o. q.d. physical examination on admission: on physical examination, the patient was in no apparent distress. his chest was clear. heart was regular rate and rhythm. neurologically, he had poor hand mobility but otherwise normal neurologic function. laboratory data on admission: notable examination values were a hematocrit of 46.5. a bun of 31, a creatinine of 1.3. radiology/imaging: electrocardiogram demonstrated t wave flattening in ii, iii, and v6; but no other gross st changes. hospital course: on the patient was operated on for rectal cancer and underwent an abdominal perineal resection under general anesthesia and tracheal intubation by dr. and dr. . 7 liters of fluid of lactated ringer's intraoperatively with 630 cc of urine output with 500 cc of estimated blood loss. the patient had 20 cm of rectum sigmoid colon removed and had an ostomy raised. he was stable to the postanesthesia care unit; however, the patient had difficulty with extubation and was transferred to the intensive care unit where he stayed overnight with ventilator settings of pressure support of 5, peep of 5, fio2 of 60, and arterial blood gas of 7.35/36/161/21/-4. the patient was successfully extubated in the morning following surgery with one notable laboratory value of creatinine of 1.7 with adequate, but borderline renal output, most likely secondary to hypovolemia. otherwise, the patient was stable, and the patient was successfully extubated and transferred to the floor where the patient was changed to maintenance intravenous fluids, and his pleurovac connected to his drains was continued on suction. the remainder of his hospital course was uneventful. his patient-controlled analgesia was discontinued, and the patient began to tolerate a clear diet, and eventually advanced to a regular diet. he was seen by physical therapy and was out of bed and ambulating. the pleurovac was discontinued, and his drain output decreased and were pulled. on postoperative day six, the patient complained of diffuse right-sided chest pain with no other associated symptoms. an electrocardiogram was done and was negative for any acute changes. the patient was changed to his home medications. his intravenous fluids were discontinued, and the patient was advanced finally to full liquids, and he had formal ostomy teaching. discharge disposition: the patient's anticipated day of discharge was pending. condition at discharge: his condition on discharge was stable. medications on discharge: 1. allopurinol 300 mg p.o. q.d. 2. zestril 10 mg p.o. q.d. 3. magnesium oxide 400 mg p.o. q.d. discharge diagnoses: status post abdominal perineal resection secondary to rectal cancer. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified insertion of endotracheal tube diagnoses: paralytic ileus benign neoplasm of colon other alteration of consciousness malignant neoplasm of rectum surgical operation with formation of external stoma causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation premature beats, unspecified 

Answer: The patient is high likely exposed to
