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: biliary obstruction major surgical or invasive procedure: : cholecystectomy, roux-en-y hepaticojejunostomy to right posterior hepatic duct and confluence of right anterior and left hepatic ducts over two 5-french feeding tubes history of present illness: 39-year-old male who underwent a subtotal gastrectomy, omentectomy, radical lymph node dissection of the left gastric area, multiple frozen sections, and feeding jejunostomy on for a 4.5-cm poorly differentiated adenocarcinoma, diffuse type, signet ring cell carcinoma with no evidence of lymph node metastases (pt2b pn0 g3 pmx). there were three out of nine lymph nodes involved. however, the radial (omental) margin was involved by invasive carcinoma. because of the positive margins and relatively few lymph nodes, he was treated for a high-risk stage ib with adjuvant chemoradiation (concurrent 5-fu followed by two cycles of 5-fu from -). he presented in with jaundice and an elevated bilirubin. an ercp on demonstrated a tight stricture in the common hepatic duct. a stent was placed and a sphincterotomy performed. he presented on with fever, abdominal pain, and elevated liver function tests, and repeat ercp was required to replace the stent. he was placed on antibiotics for klebsiella bacteremia, and a percutaneous cholecystostomy tube was placed on . repeat ercp (his most recent) was performed on and the stent was changed. he has failed followup appointments for repeat ercp. it should be noted that cytology from the ercps on and were negative for malignancy. since his last hospitalization he has been doing well at home. he states that the cholecystostomy tube has not been draining over the past several days. a ct scan of the abdomen on demonstrated intrahepatic biliary dilatation, although the biliary stent and pigtail catheter within the fundus of the collapsed gallbladder were in the expected position. he had no evidence of a portal mass or evidence of metastatic disease. therefore, it was thought that this stricture is a benign postradiation stricture. it should be noted that he has a billroth ii reconstruction. past medical history: - oncologic history: partially obstructing gastric cancer after presentation with nausea/vomiting, epigastric discomfort, intolerance of solid food and a 30lbs weight loss - diagnosed with gastric antral adenocarcinoma s/p subtotal gastrectomy with a billroth ii anastomosis, omentectomy, and radical lymph node dissection of left gastric area () s/p adjuvant chemo to - pathology revealed a exophytic (polypoid), infiltrative, annular 4.5cm, pt2b, g3, pno with 0 out of 9 lymph nodes involved. however, the radial (omental) margin was involved by invasive carcinoma (cytokeratin stain). because of the positive margins and relatively few lymph nodes, he was treated for high risk stage ib with adjuvant chemoradiation (concurrent 5fu followed by two cycles of 5fu)( to ). repeat endoscopy and ct imaging negative for recurrence in - found to have rising total bilirubin, jaundice, and worsening pruritis, s/p ercp (unsuccessful) and subsequently on , at which time a biliary stent was placed under general anesthesia social history: he lives in with his wife and has an 11 year old son. denies ethanol, tobacco, and recreational drug use. unemployed chef. family history: he has no family history of cancer. father has diabetes, mother had nephrectomy for nephrolithiasis. maternal grandmother had "stomach" cancer. physical exam: on discharge: vs: t: 98.6, hr: 98, bp: 115/72, rr: 18, sat: 94%ra gen: nad heent: mmm, no erythema cv: rrr, no m/r/g resp: ctab abd: soft, minimal tenderness, incision c/d/i. roux-tubes x2 in place coiled under dressing, capped. +bs ext: wwp, no edema pertinent results: 04:50am blood wbc-18.3*# rbc-4.42* hgb-12.0* hct-38.7* mcv-88 mch-27.3 mchc-31.1 rdw-14.4 plt ct-397 06:10am blood wbc-9.1 rbc-4.37* hgb-12.2* hct-37.3* mcv-85 mch-28.0 mchc-32.8 rdw-14.3 plt ct-472* 05:55am blood pt-12.5 ptt-29.1 inr(pt)-1.1 08:19pm blood glucose-133* urean-8 creat-0.6 na-142 k-3.9 cl-106 hco3-25 angap-15 06:10am blood glucose-98 urean-10 creat-0.7 na-136 k-4.3 cl-97 hco3-27 angap-16 04:50am blood alt-112* ast-104* alkphos-1024* totbili-1.8* 06:25am blood alt-48* ast-40 alkphos-524* totbili-1.2 08:19pm blood calcium-9.1 phos-5.0* mg-1.5* 06:10am blood albumin-3.3* hepatic u/s : impression: slight dampening of the right hepatic artery systolic upstroke and increased diastolic flow, of uncertain etiology tube cholangiogram : conclusion: excellent drainage through the right as well as the left hepaticojejunal anastomosis with no evidence of leak. brief hospital course: the patient was admitted to the transplant surgery service on . after a brief, uneventful stay in the pacu, the patient arrived on the floor npo with ngt in place, on iv fluids and peri-operative unasyn for antibiotics, with a foley catheter, and dilaudid pca for pain control. the patient was hemodynamically stable. neuro: the patient received dilaudid pca with good effect and adequate pain control. when tolerating oral intake, the patient was transitioned to oral pain medications. cv: the patient remained stable from a cardiovascular standpoint, although he was persistently tachycardic to the 100s. ekg showed sinus tachycardia, the patient reported no symptoms. vital signs were routinely monitored. pulmonary: the patient remained stable from a pulmonary standpoint; vital signs were routinely monitored. good pulmonary toilet, early ambulation and incentive spirometry were encouraged throughout hospitalization. gi/gu/fen: post-operatively, the patient was made npo with iv fluids. ngt was placed in the or and discontinued on pod2. his diet was then advanced when appropriate, which was well tolerated. patient's intake and output were closely monitored, and iv fluid was adjusted when necessary. foley was removed on pod3. electrolytes were routinely followed, and repleted when necessary. jp bilirubin was sent on pod1 which was normal. his jp drain was removed on pod3. his roux tubes were capped after tube cholangiography on pod5. he received an h2 blocker during his stay for prophylaxis. id: the patient's white blood count and fever curves were closely watched for signs of infection. he received 3 doses of perioperative unasyn, and was placed on oral ciprofloxacin for drain prophylaxis. hematology: the patient's complete blood count was examined routinely; no transfusions were required. prophylaxis: the patient received subcutaneous heparin and venodyne boots were used during this stay; was encouraged to get up and ambulate as early as possible. at the time of discharge, the patient was doing well, afebrile with stable vital signs. the patient was tolerating a regular diet, ambulating, voiding without assistance, and pain was well controlled. the patient received discharge teaching and follow-up instructions with understanding verbalized and agreement with the discharge plan. medications on admission: tylenol prn discharge medications: 1. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po q4h (every 4 hours) as needed for pain. disp:*30 tablet(s)* refills:*0* 2. ciprofloxacin 500 mg tablet sig: one (1) tablet po q24h (every 24 hours). disp:*30 tablet(s)* refills:*2* 3. ursodiol 300 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 4. docusate sodium 100 mg tablet sig: one (1) tablet po twice a day. disp:*60 tablet(s)* refills:*0* discharge disposition: home with service facility: vna discharge diagnosis: h/o gastric ca bile duct stricture from radiation discharge condition: mental status:clear and coherent level of consciousness:alert and interactive activity status:ambulatory -
