resection and chemoradiation , complicated by radiation proctitis, now with lower gi bleeding and dropping hematocrit from 30 to 16 status post 7 units transfusion. comparison: mr enterography and a ct torso with contrast . technique: mdct helical images were acquired through the abdomen and pelvis before and after administration of 150 ml of omnipaque intravenous contrast using the mesenteric cta protocol. sagittal and coronal reformats were generated and reviewed. findings: moderate-sized bilateral simple pleural effusions with compressive atelectasis of the lung bases are seen. the imaged portion of the heart demonstrates moderate coronary arterial calcification. there is no pericardial effusion. cta: the abdominal aorta has moderate atherosclerotic calcifications, without evidence of aneurysmal dilation. minimal calcifications are seen at the origin of the celiac, sma and renal arteries, with normal opacification of the vessels distally. the inferior mesenteric artery is patent. incidental note is made of a replaced right hepatic artery. there is no evidence of active hemorrhage within the small/large bowel loops. prominent vessels are seen along the wall of the cecum and proximal ascending colon, without evidence of active bleed. no significant retroperitoneal or mesenteric lymphadenopathy is seen. multiple hypodense lesions are seen in both kidneys, consistent with simple renal cysts, with the largest in the lower pole of the right kidney measuring 3.9 cm and the largest exophytic cyst in the lower pole of the left kidney measuring 5.4 cm. both kidneys enhance and excrete contrast symmetrically. mild right hydroureteronephrosis has progressed since the prior study and ureter is dilated up to the level of the pelvic inlet and likely relates to post-radiation changes. the spleen and pancreas are normal. the right adrenal gland is normal. nodular thickening of the left adrenal gland, is stable since the earlier study of . ct of the pelvis with intravenous contrast: multiple stones seen along the dependent aspect of the urinary bladder, likely relate to chronic outlet obstruction. diffuse thickening of the rectal wall with perirectal fat stranding, likely represent post-radiation changes. evidence of prior surgical anastomosis is seen in the the rectum. small bilateral lymph nodes seen along the external iliac chain do not meet ct criteria for significant adenopathy and are stable since the prior study. there is no pelvic free fluid. bones and soft tissues: no bone lesions suspicious for infection or malignancy are detected. moderate degenerative changes are seen in the lumbar spine, worse at l2-l3 level, with near complete reduction of disc space and mild retrolisthesis of l2 on l3 . impression: 1. no evidence of active gastro-intestinal bleeding. 2. bilateral moderate simple pleural effusions with compressive atelectasis of the lung bases. 3. atherosclerotic disease of the abdominal aorta, without aneurysmal dilation. 4. bilateral simple renal cortical cysts. mild right hydroureteronephrosis, possibly secondary to radiation. 5. post-radiation changes in the pelvis. multiple bladder stones. . egd: esophagus: lumen: a sliding small size hiatal hernia was seen. stomach: mucosa: localized congestion and nodularity of the mucosa were noted in the stomach body. protruding lesions a single 5 mm polyp of benign appearance was found in the fundus. duodenum: mucosa: normal mucosa was noted. impression: small hiatal hernia congestion and nodularity in the stomach body polyp in the fundus normal mucosa in the duodenum otherwise normal egd to proximal jejunum. . enteroscopy: findings: esophagus: normal esophagus. stomach: normal stomach. duodenum: normal duodenum. jejunum: flat lesions two small localized lymphangiectasia were seen in the mid jejunum and distal jejunum. ileum: not examined. other findings: a few pills were seen in the mid jejunum. there was no stenosis or sticture noted in the jejumum distal to the pills. no angioectasia or active bleeding was seen in the examined small bowel. impression: lymphangiectasia in the mid jejunum and distal jejunum a few pills were seen in the mid jejunum. there was no stenosis or sticture noted in the jejumum distal to the pills. no angioectasia or active bleeding was seen in the examined small bowel. otherwise normal single balloon small bowel enteroscopy to distal jejunum recommendations: please follow with in-patient gi consult team. please look for other sources of gi bleeding. . colonoscopy: findings: mucosa: ulceration and friability with contact bleeding were noted in the rectum. these findings are compatible with radiation proctitis. the opening out of the rectum was tight. it was off to the side of the rectal channel. it was found by using the pedi gastroscope first. once this lumen was intubated, i changed to the gastroscope. with this scope, got to the hepatic flexure. i then changed scopes to the pedi colonoscope and was able to enter the lumen and go to the cecum. the presence of the large ventral hernia made passage difficult. except for the rectum, the rest of colon is normal. there was no fresh blood or melena above. no ischemia, angioectasia, polyps or tumor. other the ileum was not intubated. impression: ulceration and friability in the rectum compatible with radiation proctitis otherwise normal colonoscopy to cecum brief hospital course: 84 yo m with rectal cancer s/p chemoradiation and resection, chronic incontinence, afib, cad s/p cabg, dchf and severe as, presenting with 3 days of melena and a hct of 16 from 30. . # gi bleed: pt presented with large amount of melena, and incontinent due to surgery. thought to be an upper gi bleed due to presence of melena. started on iv ppi and made npo. had an egd performed while in the showing no evidence of bleeding down to the jejunum. received a total of 7 units prbcs and 2 units of platelets. hct remained stable post-egd and patient was called out to the floor. while on the floor had continued melena and underwent an enteroscopy that was unrevealing. the patient was then prepped for 2 days and underwent a colonscopy that revealed radiation changes to the rectum but no source for brisk bleed. the pt received 1prbc prior to discharge. (his hct was mid 24's prior to the prbc transfusion). the patient was discharged with plans for a hct check the day following discharge and to follow-up with (gi) for a potential outpatient capsule endoscopy. . # atrial fib: pt currently in nsr on dofetilide and prn metoprolol at home. dofetilide continued. metop held due to gi bleed. pt instructed to restart on discharge after discussion with his pcp. . # cad: initially held metoprolol and aspirin. pt instructed not to restart asa until instructed to do so. . # hypokalemia: pt noted to be hypokalemic to low 3s for 3 days prior to discharge. this was repleted daily. the patient was instructed to get his electrolytes checked the day after discharge and have them repleted as needed. etiology was likely secondary to loose stools/diarrhea while in house. transitional: - direct verbal signout was given to pcp () and gi () prior to d/c. - he will see dr. in clinic this tuesday and have his results faxed to dr. office. medications on admission: vitamin b12 1000mcg/ml im monthly dofetilide 250mcg metoprolol succinate 25mg prn sbp>110 quinapril 2.5mg daily prn sbp>110 alpha lipoic acid aspirin 81mg daily co q digestive enzymes lactobacillus mvi omega 3 discharge medications: 1. dofetilide 250 mcg capsule sig: one (1) capsule po q12h (every 12 hours). 2. quinapril 5 mg tablet sig: 0.5 tablet po daily (daily). 3. omeprazole 40 mg capsule, delayed release(e.c.) sig: one (1) capsule, delayed release(e.c.) po twice a day. disp:*60 capsule, delayed release(e.c.)(s)* refills:*2* 4. outpatient lab work please have a cbc and chem-7 checked and faxed to dr. at . 5. metoprolol tartrate 25 mg tablet sig: one (1) tablet po twice a day. 6. outpatient lab work outpatient lab work please have a cbc and chem-7 checked and faxed to dr. at . discharge disposition: home discharge diagnosis: primary diagnosis - acute blood loss anemia secondary to gi bleed . secondary diagnosis - atrial fibrillation - htn - coronary artery disease discharge condition: mental status: clear and coherent. level of consciousness: alert and interactive. activity status: ambulatory - requires assistance or aid (walker or cane). discharge instructions: you were admitted to the hospital with low blood levels. you received several blood transfusions and underwent endoscopies that unfortunately did not pinpoint the site of bleeding. . please continue to take your medications and note the changes that we have made to your regimen. we have started you on a medication called omeprazole 40mg that you should take twice a day until instructed to decrease or stop by dr. . . please do not take aspirin until instructed to do so by your doctors. followup instructions: please have your blood checked tomorrow and have the results fax: . tuesday 9:15am dr. department: hematology/oncology when: friday at 7:30 am with: , lpn building: campus: east best parking: garage department: podiatry when: monday at 3:10 pm with: , dpm building: none campus: off campus best parking: on street parking department: hematology/oncology when: friday at 9:00 am with: , md building: sc clinical ctr campus: east best parking: garage procedure: other endoscopy of small intestine other endoscopy of small intestine colonoscopy diagnoses: congestive heart failure, unspecified acute posthemorrhagic anemia atrial fibrillation coronary atherosclerosis of unspecified type of vessel, native or graft aortocoronary bypass status aortic valve disorders hypopotassemia blood in stool diastolic heart failure, unspecified other specified disorders of rectum and anus radiological procedure and radiotherapy as the cause of abnormal reaction of patient, or of later complication, without mention of misadventure at time of procedure benign essential hypertension personal history of malignant neoplasm of rectum, rectosigmoid junction, and anus benign neoplasm of stomach full incontinence of feces
