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: no known allergies / adverse drug reactions attending: chief complaint: abdominal pain major surgical or invasive procedure: : picc line placement history of present illness: mr. is a 80 year old man with crohn's disease s/p recent laparotomy, lysis of adhesions, and ileocecectomy with end ileostomy on for small bowel obstruction and anastamotic stricture. he was discharged to rehab on after return of bowel function, tolerating a regular diet, on a steroid taper. he remained at rehab until today when he began having increasing abdominal pain after eating a large breakfast. he denies nausea and continued to have ileostomy output. he was taken to hospital where a ct scan showed a small amount of free intraabdominal air. he was reportedly hypotensive at the osh. he was transferred to our ed for further evaluation. upon arrival, his blood pressure was initially 86/58 however subsequently improved with a sbp in the 110s. upon evaluation in the ed he actually reports the pain has improved somewhat. past medical history: past medical history: crohn's disease, cva, pe, ivc filter, copd past surgical history: ileocecectomy ~30 years ago, ileocectomy and take down of duodenal fistula as above social history: the patient lives at home with his wife. quit smoking 18 years ago. he drinks ~1 glass of wine per night..used to drink at least 4 cocktails per night. he worked in real estate. family history: nc physical exam: on admission: vitals: 99.8f 95 86/58 -> 110/60 16 100% ra gen: a&o, lying in bed, nad heent: no scleral icterus, mucus membranes

01:59pm blood lactate-2.6* 02:26am blood lactate-1.3 ct abd : impression: 1. 16 mm splenic artery pseudoaneurysm with focus of mural calcification. 2. multiple intra-abdominal fluid collections which contain foci of gas with rim enhancement. findings may be simply secondary to irrigation following laparotomy; however, intra-abdominal fluid collections or abscesses could have a similar appearance. 3. unusual linear hyperdense focus in the third part of duodenum is of uncertain etiology but appears intraluminal and likely represents an ingested material. 4. satisfactory appearance following extended cecectomy and end ileostomy. mild ileal mural thickening is suggestive of an enteritis but may be secondary to ongoing intra-abdominal inflammation. 5. diverticulosis, but no evidence of acute diverticulitis at this time. 6. small abdominal aortic aneurysm measuring 3.2 cm. ct abd : 1. the intra-abdominal abscess is overall of similar volume compared to , although the shape is variable. a tiny fluid tracks to the right upper quadrant with small foci of free air adjacent to the gallbladder, unchanged. 2. gallbladder distention, with nonspecific wall stranding in the setting of anasarca. distention is similar to but increased from . if clinically indicated, hida could be performed for further evaluation. 3. abdominal aortic aneurysm to 3.1 cm is unchanged. marked stenosis of the celiac artery origin and mild stenosis of sma origin due to atherosclerotic plaque. 4. bilateral pleural effusions are increased from . 04:05am blood alt-20 ast-13 alkphos-77 amylase-27

stricture and enteroenteric fistula, presented to with a lactate of 4, a dirty u/a, and intraabdominal abscesses on ct abd. he was admitted to the icu for aggresive fluid resuscitation. over the course of his three days in the ticu he was administered 10 l crystalloid and albumin. his lactate improved and pressors were weaned. he was started on iv vanco and zosyn. ir was consulted for possible drainage of his multiple intraabdominal abscesses but it was determined initially that the abscesses were not amenable to drainage. a discussion was had with the patient's hcp regarding operative washout but the family decided against surgical intervention. given his improved exam, laboratory values and stable hemodynamics, he was transferred to the floor on tolerating sips of fluids. on the floor maintenance iv fluids were continued and he remained hemodynamically stable. he remained afebrile and his wbc count trended downward to normal. however, he continued to have decreased oral intake and leukocytosis and so a repeat ct scan was obtained on to assess whether the prior noted fluid collections would be amenable to drainage. however, the collections again were determined to not be amenable to drainage. therefore, his iv antibiotics were continued but changed to cipro and flagyl for empiric coverage of his abscesses. a cvl in his right ij had been placed on admission, and was removed on . a picc line was inserted at that time with a plan for a 2 week total course of iv cipro/flagyl. his diet was slowly advanced as tolerated. nutritional supplements were added to his diet. he was able to tolerate a regular diet without nausea/vomiting or abdominal pain. his home medications were resumed at that time and iv hydrocortisone was discontinued and his po prednisone taper was resumed per gi recommendations from prior admission for management of crohn's. as his oral intake increased, his ileostomy output was noted to increase as high as 2 liters per day. on he was started on loperamide for this. he also required daily repletions of his electrolytes. his urine culture from admission return as mrsa. he had received 4 days of vancomycin coverage for this prior to his antibiotics being changed to cipro/flagyl. a foley catheter was inserted on admission given aggressive resuscitation and need for urine output monitoring. it was removed on ; however, he failed to void and the foley was replaced for urinary retention. he was encouraged to mobilize out of bed and ambulated as tolerated with a walker, with which he required assistance. physical therapy was consulted for evaluation who recommended discharge to rehab when medically stable. he was started on sc heparin for dvt prophylaxis. his pain level was routinely assessed and well-controlled with tylenol. of note, pt's inr was elevated on admission and throughout his hospital course (1.7-2.4). this was thought to be likely due to malabsportion and poor nutrition, and he was given iv vitamin k 2 mg x 2 and his inr came down to 1.4. on he is afebrile and hemodynamically stable. he is tolerating a regular diet without abdominal pain or nausea/vomiting. his wbc count is within normal limits and he is making adequate amounts of urine. he is being discharged to rehab to continue his recovery. medications on admission: 1. pantoprazole 40 mg po q24h 2. mesalamine 1200 mg
