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: neurontin / beta-blockers (beta-adrenergic blocking agts) / ace inhibitors attending: chief complaint: pancreatic head mass, failure to thrive, chronic abdominal pain major surgical or invasive procedure: exploratory laparotomy, intraoperative ultrasound, j tube placement, take back for bleeding at mesentery history of present illness: this 63-year-old chef has been relatively healthy with the exception of chronic migraines and back pain, and hypertension. he has suffered from other pain problems such as knee pain and neck spondylosis over time. he has had a history of asthma and melanoma as well. most notably, however, is that he had a distal gastrectomy with billroth ii reconstruction in for peptic ulcer disease. he has also had a cholecystectomy in the past as well as a melanoma excision. his problem is that of an unrelenting epigastric pain diagnosed as chronic pancreatitis elsewhere. this has been going on since . apparently, he has had an endoscopic ultrasound evaluation by dr. at which time he felt the distal pancreas accessible through the stomach showed evidence of chronic pancreatitis. subsequent to that, he was referred to dr. for another endoscopic ultrasound and was unable to access the pancreatic head due to the billroth ii reconstruction again. a ct scan has been performed and this shows a hypodensity in the posterior pancreatic head which is worrisome for either a malignancy or a focal pancreatitis problem. i will note that there is no evidence of ductal dilation of either his bile duct or pancreas duct, however, and the rest of his pancreas tissue looks normal to me. there is no evidence of a distinct pancreatitis sequelae or destruction. currently, he is at his wits end with his progressive abdominal pain, which has been with him since . it is epigastric and does not radiate to the back. it is worse after eating. he has nausea and vomiting with this. he has lost 30 pounds over this time. he is on a fentanyl patch at this point for pain. he has no distinct history of current alcohol abuse. he said he did drink some alcohol, but not had abusive levels in the past. he stopped years ago when he felt that alcohol was not a good interaction with his pain pills used for treatment of his migraines and other back pain problems. past medical history: pmh: migraines, back pain l5 fx, gastric ulcer, htn, bph, knee pain, asthma, h/o melenoma, neck spondylosis psh: antrectomy with bii in , tonsillectomy, melanoma excision, open ccy social history: previous etoh but not abused. family history: nc physical exam: in office with dr. : his abdomen is soft but tender in the epigastric region and he has some left lower quadrant tenderness as well. he has a well-healed right subcostal incision, which crosses the midline. rectal exam was deferred. there is no evidence of any hernias or masses in his inguinal exam. the rest of physical exam is relatively normal. pertinent results: ctap: 1. ill-defined hypoenhancing heterogeneous area in the pancreatic head. given the lack of pancreatic or biliary ductal dilatation findings could represent focal pancreatitis; however, a neoplastic process cannot be excluded. therefore further evaluation with mri is recommended. 2. multiple hypodensities in the kidneys bilaterally which are too small to characterize. there may be a thin septation within a cystic lesion in the upper pole of the right kidney and attention to this area on the mri is recommended. brief hospital course: mr. presented to for operative exploration and possible whipple due to considerable concern of a pancreatic head mass associated with chronic abdominal pain. in the or, a bilateral subcostal incision was made as well as adhesiolysis to free the bowels. after performing a maneuver, no mass was felt in the pancreas. a curious, plump-looking lymph node was biopsied. on frozen section, foreign body giant cell reaction but no evidence of malignancy or other process. intraoperative ultrasound was performed as well which showed absolutely no abnormalities of pancreatic parenchyma. the pancreatic head was devoid of any masses. the pancreatic duct and bile duct were normal. dr. was contact and it was collectively decided to place a feeding jejunostomy tube to allow enteral feedings and the patient was closed. approximately 7 hours postoperatively, the patient showed signs of hypovolemia, with falling urine output and hematocrit. thus, he was taken back to the or emergently whereupon a bleeding vessel was found and ligated. after hemostasis was achieved, the patient's bp and urine output rose accordingly. because of the large amount of blood loss, the patient was taken to the surgical icu postoperatively. there, serial hcts were checked to ensure stability as well as intensive monitoring of hemodynamics and urine output. in total, the patient received 7 units of packed red blood cells and 1 unit of fresh frozen plasma. as his condition improved, his ng tube was discontinued and he was started on tube feeds as his bowel function returned. he was seen by the chronic pain service and was given a regimen on which he could go home. his condition slowly improved and his diet was advanced as appropriate. on the floor he remained stable and he was ultimately discharged afebrile, with stable hemodynamics, urinating on his own, tolerating a regular diet supplemented with jejunal feedings. he will follow up with dr. in clinic. medications on admission: albuterol 2 puffs prn, amlodipine 10', celebrex
