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 55-year-old male with a past medical history significant for rectal cancer in , status post low anterior resection with diverting loop ileostomy and subsequent takedown (in ). the patient did well but was noted to have a rising ca level recently. he underwent positron emission tomography and computed tomography scan with a biopsy of the surgical bed. the workup was positive for cancer. past medical history: 1. rectal cancer; status post preoperative chemotherapy and radiation therapy, low anterior resection, diverting loop ileostomy, and takedown. 2. status post left shoulder arthroscopic surgery. 3. hypertension. 4. history of deep venous thrombosis; status post ileostomy takedown. medications on admission: 1. diovan. 2. zantac as needed. allergies: no known drug allergies. social history: positive tobacco of 50 pack years. positive ethanol with approximately three beers per day. hospital course: the patient was admitted to the on and taken to surgery where he underwent a pelvic accentuation with colostomy ileal loop and splenic mobilization. intraoperatively, the patient had an estimated blood loss of 4000 ml. he received eight units of packed red blood cells, and seven units of fresh frozen plasma, as well as nine liters of crystalloid, and one liter of hetastarch. the patient was subsequently transferred to the cardiothoracic intensive care unit for continued monitoring. he was on an epidural for pain control. in the period following the surgery, the patient was followed by urology for his ileal loop as well as by the acute pain service, and of course by the primary general surgery team. the patient was transferred to the regular surgical floor on postoperative day one. on postoperative day five, the patient's pain medications were changed from patient-controlled analgesia to pain medications by mouth. on postoperative day six, the patient was also seen by radiology/oncology with recommendations left. these included consideration of systemic therapy after repeat of cea and computed tomography scan. while on the floor, the patient received ostomy teaching from the stoma nurse. on postoperative day eleven, the patient's ostomy output was noted to be diminished, and an ostomy catheter was placed a copious amount of brown-formed stool subsequently filling the patient's ostomy bag. the patient was deemed stable and ready for discharge home on postoperative day twelve (which was ). condition at discharge: condition on discharge was stable. discharge instructions/followup: 1. the patient was to follow up with dr. following discharge. 2. the patient was also to follow up with urology following discharge. 3. the patient was to receive services for ostomy care. 4. the patient was also expected to follow up with oncology following discharge. , m.d. dictated by: medquist36 procedure: radical cystectomy formation of cutaneous uretero-ileostomy repair of fistula involving bladder and intestine anterior resection of rectum with synchronous colostomy diagnoses: esophageal reflux unspecified essential hypertension secondary malignant neoplasm of other specified sites malignant neoplasm of rectum acute cystitis intestinovesical fistula other chronic cystitis
