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 48-year-old male who was well known to the surgery service having had a malignant pheochromocytoma resected in . at the time he had multiple small liver metastases and a very large malignant pheochromocytoma. the decision at that time was to observe his liver metastases. hence, the endocrinologist thought that this would not create a problem. the patient represented to in late with distention and difficulty having bowel movements. he was also found to have hypoxia based on shunting. no pulmonary embolism was found. the patient had massive hepatomegaly which may have been the cause of some of his pain. the patient was transferred to and underwent a ct scan which confirmed the finding at . we made multiple efforts to decompress the colon with enemas and cathartics but this did not work. there was some question as to whether he had a small bowel obstruction. the patient did not progress and the decision was made to take him to the operating room on . at this point, the patient had been transferred to the icu because of difficulty breathing. we were hoping to do colonoscopy with the patient intubated but the gi service felt that was probably not an option given his tenuous state. lysis of adhesions showed a transition point in the mid jejunum with some lysis of adhesions but this did not appear to be the cause for his bowel obstruction. the patient developed acute renal failure requiring dialysis. by the hope was that he can be weaned from the ventilator. he continued to require labetalol and nicardipine to control his blood pressure. by , the patient had worsening chest x- ray consistent with pneumonia. he was extubated on but no real progress was made on his ileus. he was started tpn. at this point consideration for colonoscopy was reopened with the gi team. the endocrine team recommended starting doxazosin. the gi service continued to be reluctant to perform colonoscopy. by the patient was felt to be stable but no progress was made in terms of gi function. the decision was made to try to a gastrografin enema both for diagnosis and treatment as recommended by the gi service. the patient continued to be somewhat unstable but was unable to maintain his ventilatory status without intubation. by he had a couple of small bowel movements after the gastrografin enema and the ng tube was removed because of lack of output and discomfort. unfortunately by the patient continued to do poorly and we felt that we had to do a decompressive laparotomy for his pseudoobstruction with high bladder pressures. on the beginning of the operation he desaturated and the feeling was that he probably had an endobronchial on the right and a left chest tube was placed and the endotracheal tube was pulled back. decompressive laparotomy showed massive dilated loops of bowel without specific obstruction. the cecum was very distended and cecostomy tube was placed with a 26 foley. the abdomen was left open. after this operation, the patient continued to deteriorate with worsening respiratory status. on the opened abdomen was removed and bowel was visualized and appeared to be pink and viable. there was some question as to whether it was not viable, but this did not seem to be the case. the patient continued to require high-dose pressors without much response. a family meeting was held with the patient's wife and they decided that given his current status and his underlying condition, that they would proceed with comfort measures only. on , the patient expired at 5:20 p.m.
