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: nausea, dry heaves. major surgical or invasive procedure: - sigmoid colectomy with hartmann's, end colostomy history of present illness: pt is a 73 y/o f who was recently discharged after being treated for complicated diverticulitis as well as being evaluated for a distal pancreatic mass (likely ipmn). she now returns to the hospital with 2 days of intractable nausea with dry heaves. her vomiting has never been productive. she is passing flatus and having normal bowel movements. since discharge she has been pain free but generally has a sense of pelvic fullness. she has no pain now, just nausea. she has been eating "ok" until yesterday - small frequent meals - but reports that she has had a 20lb wieght loss in the past month, 6lbs in past week. she denies fever, chills, rhinorrhea, cough, sore throat, chest pain, shortness of breath, abdominal/back/shoulder pain, dysuria, hematuria, brbpr, change in bowel movements. she completed her cipro and clinda three days ago. past medical history: diverticulitis, cerebral aneurysm with sah s/p clipping, back surgery, right femoral angioplasty, htn, hysterectomy social history: no tobacco, drugs, 1ppd cigs for 60 yrs, lives at home family history: her mother died of a stroke at 89; her father died of alzheimer. no one in the family has colon cancer. physical exam: on admission: 98.9 103 127/76 18 96ra alert oriented x 3 nad ncat mmm no icterus or jaundice rrr no murmurs ctab no crackles wheezes or rhonchi abd

left posterolateral wall of the bladder. while by size criteria, this is potentially drainable, its location and approach is unfavorable for percutaneous drainage. 2. changes of chronic pancreatitis, with pancreatic calcifications. 4-mm rounded calcific focus in the pancreatic duct within the tail of pancreas, with dilated pancreatic duct distally. 3. several cystic lesions in the pancreas, the largest in the pancreatic tail, which may represent dilated side branches from chronic pancreatitis, side branch ipmn, or small pseudocysts. these can be evaluated with mrcp in six months on a non-emergent basis . egd: erythema in the antrum compatible with mild gastritis (biopsy) inflammatory polyp in the cardia otherwise normal egd to third part of the duodenum . operative report: preoperative diagnoses: sigmoid phlegmon with pelvic abscess. postoperative diagnoses: sigmoid phlegmon with pelvic abscess. procedure performed: 1. low anterior resection. 2. hartmann turn-in. 3. sigmoid colostomy. 4. drainage of pelvic abscess. anesthesia: general. indications for operation: this was a 73-year-old woman who entered the hospital in transfer from an outside facility approximately 3 weeks earlier with lower abdominal discomfort and an apparent sigmoid colon phlegmon on ct scan. she appeared to have a contained abscess there. she had extensive diverticulosis in the other areas of her colon on the ct scan, and a presumptive diagnosis of complicated diverticulitis was made. she was also found to have cystic dilatation of the pancreas, potentially suggestive of intraductal papillary mucinous neoplasia. i initially treated the patient with antibiotics as an inpatient. her white blood cell count, which had been approximately 14,000, fell to normal. her pain resolved. her diet was successfully advanced. she was able to be discharged to home. there, she completed a full course of outpatient antibiotics. i had seen her as an outpatient a few days after cessation of the antibiotics, at which time she reported having no abdominal pain. however, she did complain of mild nausea and her family reported a 20-pound weight loss over the previous few months, with reportedly 6 pounds of weight loss only in the past 10 days since she had gone home. i had planned to obtain an outpatient upper endoscopy with endoscopic ultrasound for the purposes of a potential transgastric biopsy of the pancreas. while the patient had been hospitalized, a cea had been sent which was 14, three times normal. a ca19-9, however, was normal. two days after i had seen the patient as an outpatient, i was called to be told that she was extremely nauseated and unable to leave her bed. her family was quite alarmed. i readmitted her to the hospital. her white blood cell count was again 15. a ct scan showed persistent inflammation of the sigmoid with enlargement of her abscess, now measuring 4.5 cm. she was placed on antibiotics again. i obtained an upper endoscopy to rule out any type of intrinsic gastric mass. it showed mild gastritis only, there was no obstruction. i had already decided to forego the transgastric biopsy. she was started on intravenous nutrition. i was concerned that nonoperative management had only led to a progressive decline. it remained possible that she either had an unusual form of perforated colon cancer as opposed to severe diverticulitis. i decided to not perform a preoperative sigmoidoscopy due to my concern of inducing an acute perforation. accordingly, approximately 48 hours after her readmission and following a mechanical bowel prep, she was brought to surgery. description of procedure: the procedure was performed in the operating room of the , . the patient was brought into the room and laid supine on the table. she was successfully induced and intubated for general endotracheal anesthesia. pneumatic compression boots were applied. a foley catheter was inserted. she was placed into lithotomy with appropriate padded supports. her preoperative ciprofloxacin had been continued. she was also continued with her preoperative flagyl. in addition, for additional perioperative coverage, she was given 2 grams of intravenous kefzol and 100 mg of intravenous gentamicin. we prepped the abdomen with betadine and sterilely draped. i made a midline incision extending from the pubis to slightly above the umbilicus. the patient had a prior hysterectomy, and at the time of her exploration, i also concluded that she had undergone bilateral salpingo- oophorectomy and appendectomy. regardless, after opening the abdomen, she had no evidence of ascites. there was no carcinomatosis. there were no adhesions. retractor was placed. she had, as expected, an intense inflammatory process in the left lower quadrant and pelvis. her sigmoid colon was extensively adherent to multiple surrounding structures. she appeared to have a very redundant cecum and right colon and the cecum and ileocecal junction were extensively involved with the inflammatory process. i engaged in a laborious dissection to separate the cecum and ileum from the area of the sigmoid colon. we entered at least two areas of abscess formation close to the sigmoid mesentery. the patient also had a much larger abscess which essentially was centered on the dome of the bladder. however, after entering the inflammatory peel in the perivesical abscess, i concluded that there was no actual violation of the bladder itself. i could feel the patient's foley balloon with what appeared to be intact tissue, deep within the abscess cavity. in the course of mobilizing the right colon and freeing it from the inflammatory process, we induced a linear tear in what appeared to be a combination of intense inflammatory peel and some of the serosa of the terminal ileum. the patient also had one focus of inflammatory peel that had been adherent to the cecum. throughout the case, i could not be certain if some of the areas of intense desmoplastic reaction, in fact, represented a perforating colon cancer with extensive transmission throughout the pelvis. as it was late in the evening, and i felt that it would not change my operative plan at all, i did not request the pathologist to come to perform any type of frozen section. at the end of our entire procedure we ultimately repaired the linear serosal tear of the ileum with lemberted sutures of 3-0 silk. everything looked quite nice after that. after mobilizing the cecum, i packed it away along with the small bowel, giving us much better visualization of the pelvis. i mobilized the left ureter proximal to the area of inflammation and controlled it with a vessel loop. after mobilizing the cecum, the right ureter had also been displayed and remained intact throughout the case. i then engaged in an extremely arduous dissection to separate the sigmoid colon from the left ureter. i stayed close to the colon and left quite a bit of inflammatory peel behind. i entered the presacral space and took the superior sigmoid artery, controlling the proximal portion with a 2-0 silk suture ligature. the sigmoid colon was extensively thickened along its course. i was somewhat suspicious, however, because there did seem to be a more bulbous area in the midpoint of the process, potentially consistent with tumor. regardless, after entering the prepelvic space and taking down the peritoneal reflection, i found some soft rectum to work with beyond the area of inflammation. i went proximally just beyond the area of inflammation and divided the sigmoid colon with stapler using the blue 3.5-mm staple closure. i then completed the resection by dividing the rectum with a ta-60 stapler with the blue cartridge. we completed our mesenteric dissection and delivered the specimen to the pathologist. our hemostasis was good. the left ureter clearly had remained intact throughout our dissection. the urine also had remained clear. there was absolute no evidence of any leakage from the defect overlying the bladder. i then liberated the proximal sigmoid almost all the way up to the splenic flexure. we had good mobility. i formed a stoma as marked by the enterostomal therapist just to the left of the midline in the mid rectus. we took a divot of skin and then formed a cruciate incision in the rectus sheath. we brought the stoma without any difficulty at all. we then proceeded to close the midline rectus fascia with a running looped #2 pds suture. i placed a #10 - drain in the pelvis, putting the end into the perivesical soft tissue defect where the majority of the abscess cavity resided. we liberally irrigated the subcutaneous space and then closed the skin with staples. dry sterile dressings were applied. we then matured our colostomy with full-thickness interrupted sutures of 4-0 vicryl to the dermis and bowel. we had good eversion. the stoma was clearly viable. an appliance was placed. i would also note that upon manual exploration and inspection, the liver was completely normal. there was no evidence of carcinomatosis. there was no obvious retroperitoneal adenopathy. she had no other palpable colon lesions. the patient was then awakened and extubated without incident. estimated blood loss: approximately 200 ml. disposition: she was transferred to the surgical intensive care unit in stable condition. brief hospital course: mrs. underwent a ct scan in the ed which revealed severe diverticulitis with a pericolonic abscess. she was admitted to the surgical service. a picc line was placed on and tpn was initiated. gastroenterology consult was obtained to r/o an upper gi source for her nausea/wretching, and an egd performed revealed little more than a gastric polyp. as her disease was complicated by an abscess and was unresponsive to antibiotics, the decision was made to take her to the operating room for a sigmoid colectomy. see operative report for further details of the operation. . she was transferred to the icu postoperatively for close hemodynamic monitoring. antibiotics were continued. she did well overnight and was transferred to the floor the next day. her pain was initially controlled with a dilaudid pca, but this was tapered and changed to extra strength tylenol because of confusion with the narcotic. she was advanced to sips the next day. her white blood cell count was elevated to 20k on pod #1 but this spontaneously returned to over the next few days. she was out of bed on pod #1 and ambulated on pod #2. she was continued on tpn since her preoperative nutrition had been poor. on pod #4 she had some tachycardia and hypertension so was started on iv lopressor, which was transitioned to po lopressor. her ostomy began to function on pod #5 and her diet was advanced to regular diet. the tpn was discontinued on pod #6. her foley was left in place, and a cystogram was performed on , which revealed no bladder injury. foley catheter was dc'd and the patient voided on her own. she was discharged to home with services on medications on admission: lisinopril 20', simvastatin 40', colace, mvi discharge medications: 1. lisinopril 20 mg tablet sig: one (1) tablet po daily
