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 77-year-old male with a very complicated past medical history. he was seen at an outside hospital where he was found to have a perforated sigmoid colon. he underwent a sigmoid resection with colostomy and hartmann's on . intraoperatively, drain was placed. the postop course was complicated by a rise in inr to 4 requiring 8 of ffp. he was also noticed to have some abdominal tenderness and a dusky ostomy, and thus a ct scan was performed which showed ileus and no fluid collection. the family requested transfer on postop day #5 to where the patient came for further care and evaluation. past medical history: 1. hypertension. 2. pmr. 3. spinal stenosis. 4. copd, on steroids and home o2. 5. chronic pneumonia. 6. paroxysmal atrial fibrillation. 7. impaired glucose tolerance. 8. gerd. 9. abnormal lfts, status post stent of common bile duct stricture and stone removal. 10.benign colon polyps. past surgical history: 1. appendectomy. 2. sigmoid resection, colostomy and hartmann's, . allergies: sulfa. meds on transfer: 1. ativan 0.5 q 4 h prn anxiety. 2. albuterol mdi 2 q h prn. 3. tylenol prn. 4. meropenem. 5. protonix 40 mg iv qd. 6. lasix 20 iv q am. 7. solu-medrol 40 iv qd. 8. advair 250/50, 1 inhaler . meds at home: 1. coumadin 7.5 mg po qd. 2. prednisone 10 mg po qd. 3. lasix 20 mg po qd. 4. potassium chloride 10 mg po qd. 5. iron 325 qd. 6. tylenol #3 prn. 7. aciphex 20 mg po qd. 8. flovent. 9. serevent. 10.albuterol. social history: denies tobacco or etoh. family history: positive for father dying of colon cancer at age 67. exam on admission: the patient is afebrile. his vital signs are normal. he is anicteric. his lungs are clear with decreased breath sounds at the bases. his heart is regular. his abdomen is distended, diffusely tender, with some inferior ecchymosis and erythema around his wound. extremities have some painful varicosities and 2+ pitting edema. rectal -
