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 62-year-old male with a very longstanding history of reflux disease which, in recent months, has significantly worsened. the patient had an upper endoscopy performed prior to admission which showed a nonbleeding nodular mass found at 40 cm to 42 cm in the esophagus, occupying approximately 50% of the lumen. biopsies of the mass were performed at that time which showed glandular dysplasia, high-grade, arising in the background of esophagus with chronic inactive gastritis. no invasive carcinoma was identified at that time. the patient has remained largely asymptomatic except for persistent heartburn. he had no symptoms of dysphagia, weight loss, or blood loss. there were no symptoms of nausea, vomiting, or abdominal pain. also, there was no family history of esophageal cancer. the patient was seen in the office by dr. , and a surgical intervention was recommended. in addition, an endoscopic ultrasound was performed at the same time which showed a mass involving the muscularis propia; consistent with a t2 lesion. in addition, there was a small less than 10-cm lymph node noted which did not appear to be hypoechoic, was not rounded, and did not have sharp margins; and thus did not appear to have any endosonographically malignant features. consequently, the patient presented for surgery. past medical history: 1. anxiety. 2. reflux disease. 3. barrett esophagitis. 4. hypercholesterolemia. 5. history of hepatitis a. past surgical history: none. social history: history of alcohol use. medications on admission: lipitor and prilosec. allergies: an allergy to penicillin (which give hives). physical examination on presentation: physical examination revealed blood pressure was 140/69, heart rate was 82, oxygen saturation was 98% on room air. head, eyes, ears, nose, and throat examination was within normal limits. the neck was supple without masses, nodes, or thyromegaly. the chest was clear to auscultation and percussion bilaterally. cardiovascular examination revealed a regular rate and rhythm without murmurs, rubs, or gallops. the abdomen was soft, nontender, and nondistended. no masses were palpable. extremities revealed no signs of cyanosis, clubbing, or edema. neurologic examination was grossly intact. radiology/imaging: a computed tomography scan of the abdomen performed on showed wall thickening at the gastroesophageal junction extending along the curvature of the stomach. in addition, incidentally a 1.3-cm enhancing in the right kidney was noted as well as an 8-mm hypodense lesion in the tail of the pancreas of uncertain significance. upper endoscopy and ultrasound studies as described above. hospital course: the patient was admitted to the general surgery service. on , the patient underwent ivor- esophagogastrectomy. the blood loss was 750 cc. there were no complications. please see the full operative report for details. the patient was extubated and transported to the postanesthesia care unit in stable condition. the patient was adequately resuscitated with intravenous fluids. he was placed on a dilaudid patient-controlled analgesia for pain control with adequate relief. his postoperative hematocrit was 36.6. his heart rate was controlled with lopressor. a jejunostomy tube was placed intraoperatively. he was maintained on subcutaneous heparin and protonix. the patient continued to do well until postoperative day two when he was noted to have a decrease in his respiratory rate to 6 on . he appeared somnolent. as noted, he had been on dilaudid patient-controlled analgesia which was repeatedly pushed by both the patient and his wife. the patient-controlled analgesia was discontinued, and he was placed on morphine intravenously as needed. however, the patient became increasingly agitated. he pulled his nasogastric tube which required repositioning. the patient needed to be restrained. psychiatry was called at this time. the patient was treated with intravenous haldol and ativan and transferred to the surgical intensive care unit. given the history of alcohol use, it was thought that his symptoms were due to delirium tremens (dt). in the intensive care unit, the patient continued to be agitated, which was treated with intravenous ativan and haldol. his tube feeds were started, and he continued to be resuscitated with intravenous fluids. his electrolytes remained stable. a chest x-ray at this time showed postoperative changes with small pleural effusions. he nasogastric tube had to be repositioned by interventional radiology under fluoroscopic guidance. the psychiatry service followed the patient throughout his hospitalization. it was thought that delirium was caused by narcotics and/or benzodiazepines. however, alcohol withdrawal was also a likely contributor to his agitation and confusion. on postoperative day three, the patient was transfused with 3 units of packed red blood cells for a hematocrit of 21. a cat scan of the head was performed on which showed no evidence of acute hemorrhage. the cat scan was obtained to rule out any organic cause of postoperative delirium. the patient was intubated on without any complications. the patient also appeared to have a low-grade fever. the blood cultures and urine cultures obtained showed no growth to date. a sputum culture obtained on grew coagulase-positive staphylococcus aureus and gram-negative rods. the staphylococcus aureus was resistant to penicillin but sensitive to oxacillin, levofloxacin, gentamicin, and clindamycin. the patient continued to have good urine output. his heart rate and blood pressure remained stable. he was continued on tube feeds. the patient was started on ceftriaxone intravenously. he received chest physical therapy. the patient continued to improve slowly and was eventually weaned off of the ventilator support. he was eventually extubated. his hematocrit remained stable. his fever subsided. the patient was eventually transferred to the regular floor on levaquin and vancomycin. the nasogastric tube remained in place. on , the patient had note: dictation ended after 10.5 minutes. , m.d. dictated by: medquist36
