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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: rectal bleeding major surgical or invasive procedure: endoscopy (colonoscopy) with 3 clips placed history of present illness: 72-year-old greek man with diverticulosis, h/o adenomatous colon polyps s/p polypectomy, and h/o esophagitis and h. pylori gastritis, who presented with brbpr after undergoing polypectomy. . on , the patient underwent an outpatient colonoscopy that revealed sigmoid and distal descending diverticulosis and 2 polyps. the polyps were removed. at home, the patient subsequently had 4 episodes of bloody bowel movements and felt light-headed, prompting him to come to the ed, where he is said to have had one episode of brbpr. . the patient was admitted to the icu out of concern that the bleeding could progress. in the icu, he complained of chills and lightheadedness. he denied any chest pain, shortness of breath, palpitations, abdominal pain, nausea, vomiting, hematemesis, or melena. he did have an additional episode of brbpr, and was tachycardic to the 130s when getting up to use the commode but otherwise hemodynamically stable. his hct on admission was approx 39, but he dropped to 25.5 before being clipped (27.0 at present). the patient was given 2 units of prbc's and prepped for colonscopy, which showed a discrete localized area with pulsatile vessel was seen in the ascending colon. there was no evidence of erythema or ulceration around the area. three endoclips were successfully applied to the ascending colon for the purpose of hemostasis. he was called out to the floor after two stable serial hct's (26.3 and 27). . on admission to the floor, vitals were t98.1, hr 90, bp 164/45, rr 18, 96%. the patient noted that he had his firt bowel movement since his colonscopy about an hour ago; hs said it contained some dark red blood, much less than before. he denied further light-headedness or abdominal pain. past medical history: -
