Objective: To evaluate the local risk factors of traumatic brain injury (TBI) patients developing gastrointestinal (GI) bleeding during the early hospitalization in neurosurgery intensive care unit (NICU). Method: From September 2005 to February 2006, 41 patients admitted to NICU and 13 healthy volunteers were involved in our study. Blood samples at 24 hours, 2-3 days and 5-7 days were obtained from each patient via arterial line at 8 a.m. to measure the concentrations of serum adrenocorticotropic hormone (ACTH), total cortisol and gastrin. The collected serum was immersed in an ice bath and tested by the Immulite 1000 systems. Data were analyzed by SPSS 11.5. Results: Within 24 hours following TBI, the concentrations of total cortisol, ACTH and gastrin increased proportionally to the severity of injury, especially significant in the experimental group (P〈0.05). The concentrations of ACTH and gastrin were higher in the GI bleeding positive group than in the GI bleeding negative group, (F=1.413, P=0.253) for ACTH and (F=9.371, P=0.006) for gastrin. GI bleeding had a positive correlation with gastrin concentration (r=0. 312, P〈0.05) and a negative correlation with serum hemoglobin (Hb) (r=-0.420, P〈0.01). The clinical incidence of GI bleeding was 24.39% (10/41) in the experimental group. Within 24 hours, GI bleeding had a strong correlation with gastrin concentration (OR=26.643, P〈0.05) and hematocrit (Hct) (OR=5.385, P〈0.05). High ACTH concentration (〉100 pg/ml) increased the frequency of GI bleeding. For patients with severe TBI and treated with routine antacids, the incidence of GI bleeding was 40.91% (9/22) and the mortality rate was 20%(2/10). Conclusions: Low Glasgow coma scale scores, low Hb, high concentrations of gastrin and ACTH (〉 100 pg/ml) are risk factors and can be predictive values for post-traumatic GI bleeding. Severe TBI patients have high risks of GI bleeding with high mortality. 展开更多

Background There is great debate on the possible adverse interaction between proton pump inhibitors (PPIs) and clopidogrel. In ad- dition, whether the use of PPIs affects the clinical efficacy of ticagrelor remains less known. We aimed to determine the impact of concomi- tant administration of PPIs and clopidogrel or ticagrelor on clinical outcomes in patients with acute coronary syndrome (ACS) after percuta- neous coronary intervention (PCI). Methods We retrospectively analyzed data fi'om a "real world", international, multi-center registry between 2003 and 2014 (n = 15,401) and assessed the impact of concomitant administration of PPIs and clopidogrel or ticagrelor on 1-year composite primary endpoint (all-cause death, re-infarction, or severe bleeding) in patients with ACS after PCI. Results Of 9429 patients in the final cohort, 54.8% (n = 5165) was prescribed a PPI at discharge. Patients receiving a PPI were older, more often female, and were more likely to have comorbidities. No association was observed between PPI use and the primary endpoint for patients receiving clopidogrel (ad- justed HR: 1.036; 95% CI: 0.903-1.189) or ticagrelor (adjusted HR: 2.320; 95% CI: 0.875-45.151) (Pinteraction = 0.2004). Similarly, use of a PPI was not associated with increased risk of all-cause death, re-infarction, or a decreased risk of severe bleeding for patients treated with either clopidogrel or ticagrelor. Conclusions In patients with ACS following PCI, concomitant use of PPIs was not associated with in- creased risk of adverse outcomes in patients receiving either clopidogrel or ticagrelor. Our findings indicate it is reasonable to use a PPI in combination with clopidogrel or ticagrelor, especially in patients with a higher risk of gastrointestinal bleeding. 展开更多

AIM: To analyze the effectiveness of the endoscopic therapy and to identify prognostic factors for recurrent bleeding. METHODS: Retrospective study of patients with gas- trointestinal bleeding secondary to Dieulafoy's lesion (DL) from 2005 to 2011. We analyzed the demographic characteristics of the patients, risk factors for gastro- intestinal bleeding, endoscopic findings, characteristics of the endoscopic treatment, and the recurrence of bleeding. We included cases in which endoscopy de- scribed a lesion compatible with Dieulafoy. We exclud- ed patients who had potentially bleeding lesions such as angiodysplasia in other areas or had undergone other gastrointestinal endoscopic procedures. RESULTS: Twenty-nine patients with DL were identi- fied. Most of them were men with an average age of 71.5 years. Fifty-five percent of the patients received antiaggregatory or anticoagulant therapy. The most common location for DL was the stomach (51.7%). The main type of bleeding was oozing in 65.5% of cases. In 27.6% of cases, there was arterial (spurting) bleeding, and 6.9% of the patients presented with an adherent clot. A single endoscopic treatment was ap- plied to nine patients (31%), eight of them with adren- aline and one with argon, while 69% of the patients received combined treatment. Six patients (20.7%) presented with recurrent bleeding at a median of 4 d after endoscopy (interquartile range = 97.75). Within these six patients, the new endoscopic treatment ob- tained a therapeutic success of 100%. The presence of arterial bleeding at endoscopy was associated with a higher recurrence rate for bleeding (50% vs 33.3% for other type of bleeding) rP = 0.024, odds ratio (OR) = 8.5, 95% CI = 1.13-63.87]. The use of combined en- doscopic treatment prevented the recurrence of bleed- ing (10% vs 44.4% of single treatment) (P = 0.034, OR = 0.14, 95% CI = 0.19-0.99). CONCLUSION: Endoscopic treatment of DL is safe and effective. Adrenaline monotherapy and arterial (spurting 展开更多

To report the result of rapid ulcer healing by infliximab in Crohn's patients with severe enterocolic bleeding. During 2005 and 2010, inflammatory bowel disease database of King Chulalongkorn Memorial and Samitivej hospitals were reviewed. There were seven Crohn's disease (CD) patients (4 women and 3 men; mean age 52 ± 10.4 years; range: 11-86 years). Two of the seven patients developed severe gastrointestinal bleeding (GIB) as a flare up of CD whereas the other five patients presented with GIB as their first symptom for CD. Their mean hemoglobin level dropped from 12 ± 1.3 g/ dL to 8.7 ± 1.3 g/dL in a 3-d period. Median packed red blood cells units needed for resuscitation was 4 units. Because of uncontrolled bleeding, surgical resection was considered. However, due to the poor surgical candidacy of these patients (n = 3) and /or possible development of short bowel syndrome (n = 6), surgery was not pursued. Likewise angiographic embolization was not considered in any due to the risk of large infarction. All severe GIBs successfully stopped by one or two doses of intravenous infliximab. Our data suggests that infliximab is an alternative therapy for CD with severe GIB when surgery has limitation or patient is a high risk. 展开更多

AIM:To define which segments of the gastrointestinal tract are most likely to yield angioectasias for ablative therapy. METHODS:A retrospective chart review was performed for patients treated in the Louisiana State University Health Sciences Center Gastroenterology clinics between the dates of July 1, 2007 and October 1, 2010. The selection of cases for review was initiated by use of our electronic medical record to identify all patients with a diagnosis of angioectasia, angiodysplasia, or arteriovenous malformation. Of these cases, chart reviews identified patients who had a complete evaluation of their gastrointestinal tract as defined by at least one upper endoscopy, colonoscopy and small bowel capsule endoscopy within the past three years. Patients without evidence of overt gastrointestinal bleeding or iron deficiency anemia associated with intestinal angioectasias were classified as asymptomatic and excluded from this analysis. Thirty-five patients with confirmed, bleeding intestinal angioectasias who had undergone complete endoscopic evaluation of the gastrointestinal tract were included in the final analysis. RESULTS:A total of 127 cases were reviewed. Sixtysix were excluded during subsequent screening due to lack of complete small bowel evaluation and/or lack of documentation of overt bleeding or iron deficiency anemia. The 61 remaining cases were carefully examined with independent review of endoscopic images as well as complete capsule endoscopy videos. This anal- ysis excluded 26 additional cases due to insufficient records/images for review, incomplete capsule examination, poor capsule visualization or lack of confirmation of typical angioectasias by the principal investigator on independent review. Thirty-five cases met criteria for final analysis. All study patients were age 50 years or older and 13 patients (37.1%) had chronic kidney disease stage 3 or higher. Twenty of 35 patients were taking aspirin (81 mg or 325 mg), clopidogrel, and/or warfarin, with 8/20 on combination therapy. The number and 展开更多

An extrahepatic arterioportal fistula(APF) involving the gastroduodenal artery and superior mesenteric vein is rare and mostly results from iatrogenic injuries.The clinical symptoms associated with APFs may include abdominal pain,gastrointestinal bleeding,ascites,nausea,vomiting,diarrhea,or even congestive heart failure.We present the case of a 70-year-old man who presented with chronic abdominal pain and gastrointestinal bleeding secondary to APF and portal vein thrombosis.The endovascular embolization of APF was accomplished successfully,and symptoms of portal hypertension resolved immediately after intervention.Unfortunately,the patient did not respond well to anticoagulation therapy with warfarin.Therefore,the patient underwent implantation of a transjugular intrahepatic portosystemic shunt,and the complications of portal hypertension resolved.In conclusion,the embolization of APF is technically feasible and effective and can be considered the first-choice therapy in selected patients. 展开更多
