BACKGROUND: The role of medical treatment for patients with bleeding peptic ulcers is uncertain. METHODS: We conducted a double-blind, placebo-controlled trial in 220 patients with duodenal, gastric, or stomal ulcers and signs of recent bleeding, as confirmed by endoscopy. In 26 patients the ulcers showed arterial spurting, in 34 there was active oozing, in 35 there were nonbleeding, visible vessels, and in 125 there were adherent clots. The patients were randomly assigned to receive omeprazole (40 mg given orally every 12 hours for five days) or placebo. The outcome measures studied were further bleeding, surgery, and death. RESULTS: Twelve of the 110 patients treated with omeprazole (10.9 percent) had continued bleeding or further bleeding, as compared with 40 of the 110 patients who received placebo (36.4 percent) (P<0.001). Eight patients in the omeprazole group and 26 in the placebo group required surgery to control their bleeding (P<0.001). Two patients in the omeprazole group and six in the placebo group died. Thirty-two patients in the omeprazole group (29.1 percent) and 78 in the placebo group (70.9 percent) received transfusions (P<0.001). A subgroup analysis showed that omeprazole was associated with significant reductions in recurrent bleeding and surgery in patients with nonbleeding, visible vessels or adherent clots, but not in those with arterial spurting or oozing. CONCLUSIONS: In patients with bleeding peptic ulcers and signs of recent bleeding, treatment with omeprazole decreases the rate of further bleeding and the need for surgery.  相似文献

BACKGROUND AND STUDY AIMS: A controlled and randomized multicenter study was carried out in order to compare the efficacy of fibrin sealant and Nd:YAG laser photocoagulation in patients with high-risk arterial bleeding from peptic ulcers of the stomach and the small intestine. PATIENTS AND METHODS: In four teaching hospitals, 53 patients presenting with either active arterial ulcer bleeding (Forrest class 1 a) or a large visible vessel in the ulcer base (diameter over 2 mm, Forrest class 2 a) were treated with infiltration of epinephrine 1: 10,000 followed by the injection of fibrin tissue adhesive (n = 28), or with epinephrine plus laser photocoagulation (n = 25). Permanent hemostasis for at least seven days served as the principal end point; rebleeding, emergency surgery, and hospital mortality served as further end points. RESULTS: There were no significant differences between the study groups in terms of age, risk factors, initial hemoglobin values, number of patients showing signs of hemodynamic impairment, ulcer size and localization, or bleeding activity. Primary hemostasis was achieved in all patients. Rebleeding rates were seven of 28 and four of 25 among the patients treated with fibrin sealant and laser coagulation, respectively (not significant). There were no significant differences regarding the rates of ultimate hemostasis (24 of 28 vs. 24 of 25), emergency surgery (four of 28 vs. one of 25), or hospital mortality (0 vs. two of 25). No complications occurred with either form of treatment. Patients who had a visible vessel in the ulcer floor at the first control endoscopy had a significantly higher incidence of rebleeding, regardless of the type of endoscopic therapy. CONCLUSIONS: We conclude that both the injection of fibrin tissue adhesive and laser photocoagulation are effective methods of treating high-risk arterial peptic ulcer bleeding. As the number of high-risk patients necessary to reach significance are difficult to recruit within a reasonable period even in a multicenter study, a new meta-analysis of all studies now available should be considered.  相似文献

BACKGROUND: We evaluated whether therapy designed to eradicate Helicobacter pylori infection resulted in a reduction in rebleeding in patients with peptic ulcer disease. Patients presenting because of major upper gastrointestinal hemorrhage from peptic ulcer and whose ulcers healed in a study in which they were randomized to receive ranitidine alone or triple therapy plus ranitidine were followed up regularly with endoscopy. No maintenance anti-ulcer therapy was given after ulcer healing. METHODS: Patients received ranitidine, 300 mg, or ranitidine plus triple therapy. Triple therapy consisted of tetracycline, 2 g; metronidazole, 750 mg; and bismuth subsalicylate, 5 or 8 tablets (151 mg bismuth per tablet), and was administered for the first 2 weeks of treatment; ranitidine therapy was continued until the ulcer had healed or 16 weeks had elapsed. After ulcer healing, no maintenance antiulcer therapy was given. Development of ulcer recurrence with or without recurrent upper gastrointestinal bleeding was evaluated. RESULTS: Thirty-one patients with major upper gastrointestinal bleeding from peptic ulcer were studied; 17 received triple therapy and 14 ranitidine alone. Major rebleeding occurred significantly (p = 0.031) more often in those in the ranitidine group (28.6%), compared with none (0%) in the triple therapy group. CONCLUSION: Eradication of H. pylori infection reduces the rate of ulcer recurrence and rebleeding in complicated ulcer disease.  相似文献

BACKGROUND AND STUDY AIMS: A second-look endoscopy is often performed to evaluate the efficacy of a prior injection therapy in patients with bleeding peptic gastric or duodenal ulcers. Although this strategy is widely established, it does not rely on unequivocal data from controlled studies. In a prospective, randomized, controlled multicenter trial we assessed the effect of programmed endoscopic follow-up examinations with eventual retreatment on the outcome of bleeding ulcers in these patients. PATIENTS AND METHODS: One hundred and five patients with gastric or duodenal peptic ulcers presenting with active (Forrest type I) or recent (Forrest type IIa and IIb) bleeding upon endoscopy within four hours after admission were included in the study. Emergency treatment consisted of the sequential injection of both epinephrine (1:10,000 v/v) and up to 2 ml of fibrin/thrombin around the ulcer base. Fifty-two patients were randomized to receive programmed endoscopic monitoring with eventual retreatment in cases of Forrest type I, IIa, or IIb ulcers beginning within 16-24 hours after the index bleed. Follow-up endoscopies were continued until the macroscopic appearance revealed a Forrest type IIc or III ulcer. Fifty-three patients in the control group were closely monitored, and only received a second endoscopy when there was clinical or biochemical evidence of recurrent bleeding. The groups did not differ with respect to age, sex, site and severity of bleeding. RESULTS: The numbers of patients with recurrent bleeding were similar whether they were endoscopically monitored or not (21% versus 17%, P=0.80 chi-squared test). In addition, there was no statistically significant difference between the two groups with respect to the number of blood units transfused, need for surgical intervention, hospital stay or number of deaths (Mann-Whitney U-test). Improving local ulcer stigmata was not related to a better outcome. CONCLUSIONS: Programmed endoscopic follow-up examinations with eventual retreatment in patients locally injected for an acute or recent hemorrhage from a gastric or duodenal ulcer did not influence their outcome when compared to patients receiving only a second endoscopic intervention upon evidence for recurrent hemorrhage. Scheduled control endoscopies cannot be recommended after an initial successful endoscopic treatment of peptic ulcer bleeding when selection of the patients for second-look endoscopy is directed by the Forrest criteria.  相似文献

The efficacies of somatostatin and octreotide have been widely studied in the control of bleeding from oesophageal varices. It has also been suggested that these drugs may be useful for the control of non-variceal upper gastrointestinal (UGI) bleeding, including that from peptic ulcers. In approximately 80% of patients presenting with non-variceal UGI bleeding, haemorrhage ceases spontaneously and does not recur. However, the remaining 20% of patients require active treatment. Results from recent studies have indicated that somatostatin is an effective treatment for the control of non-variceal UGI bleeding in high-risk patients, i.e. those in whom haemorrhage does not cease spontaneously or is likely to recur. In contrast there is no good evidence available at present to support a role for octreotide in this indication. The efficacy of somatostatin in controlling bleeding in patients with non-variceal UGI bleeding at high risk of mortality upon admission, or rebleeding following endoscopy, coupled with an excellent safety and tolerability profile, suggests that it may be a valuable therapeutic option in the management of non-variceal bleeding.  相似文献

Ischemia is a rare cause of gastric and duodenal ulcers. For the present study clinical and anatomo-pathologic data from cases published so far and from twelve own patients with ischemic ulcers have been investigated. Histopathology leads to the diagnosis of an ischemic cause with great accuracy. Our results show that ischemic ulcers occur often at gastric sites unusual for a peptic ulcer, and in some cases they look macroscopically different from peptic ulcers. The most common symptom was severe gastrointestinal bleeding. Pain, typical for peptic ulcers, has only rarely been noted by patients. Lethal courses were usually due to gastrointestinal bleeding resistant to therapy. Resection of the involved gastric or duodenal segment or surgical or angiologic reconstruction of the vessels respectively are promising therapeutic means. Without therapeutic intervention very different courses have been observed, ranging from spontaneous healing to fatal gastrointestinal bleeding. The benefit of inhibitors of acid secretion is so far unclear.  相似文献

BACKGROUND/AIMS: Octreotide is used to arrest peptic ulcer hemorrhage. Since it has anti-secretory properties, it could also be used in Helicobacter pylori eradication therapy, to cure peptic ulcer before discharging patients from hospital. The aim of this pilot study was to determine safety and efficacy of an ultra short quadruple octreotide containing H. pylori eradication therapy in patients with peptic ulcer. METHODOLOGY: Twenty-six consecutive symptomatic H. pylori-positive patients with duodenal (n = 20) or gastric ulcer (n = 6), were treated with a three-day course of octreotide 0.3 mg/day subcutaneously, amoxicillin plus metronidazole 2 g/day orally and colloid bismuth subcitrate 480 mg/day. CLO-test, culture and crush tissue smears were performed on admission to the study, at 4 and 8 weeks post treatment. The effect of octreotide on intragastric pH (n = 10) was also investigated. RESULTS: Octreotide significantly increased the mean 24-hour intragastric pH > 3 over 68.9% of the time (37.1%-99.5%). There were no treatment side effects. Ulcer pain was abolished at between 2-12 days. By intention-to-treat 24/26(92.3%, 95% CI 82%-100%) ulcers had healed at 4 weeks. H. pylori eradication rate at 8 weeks was 88.5% (23/26) (95% CI 76%-100%). CONCLUSIONS: Our ultra-short octreotide containing quadruple therapy is a safe and effective regime in eradicating H. pylori and healing peptic ulcers. It may be a suitable therapy for hospitalized patients with peptic ulcer hemorrhage.  相似文献

BACKGROUND: Helicobacter pylori infection is common in patients with peptic ulcers caused by the use of non-steroidal anti-inflammatory drugs (NSAIDs). But the pathogenic role of H pylori in this disease is controversial. We studied the efficacy of eradication of H pylori in the prevention of NSAID-induced peptic ulcers. METHODS: We recruited patients with musculoskeletal pain who required NSAID treatment. None of the patients had previous exposure to NSAID therapy. Patients who had H pylori infection but no pre-existing ulcers on endoscopy were randomly allocated naproxen alone (750 mg daily) for 8 weeks or a 1-week course of triple therapy (bismuth subcitrate 120 mg, tetracycline 500 mg, metronidazole 400 mg, each given orally four times daily) before administration of naproxen (750 mg daily). Endoscopy was repeated after 8 weeks of naproxen treatment or when naproxen treatment was stopped early because of bleeding or intractable dyspepsia. All endoscopic examinations were done by one endoscopist who was unaware of treatment assignment. The primary endpoint was the cumulative rate of gastric and duodenal ulcers. FINDINGS: 202 patients underwent endoscopic screening for enrolment in the trial, and 100 eligible patients were randomly assigned treatment. 92 patients completed the trial (47 in the naproxen group, 45 in the triple-therapy group). At 8 weeks, H pylori had been eradicated from no patients in the naproxen group and 40 (89%) in the triple-therapy group (p < 0.001). 12 (26%) naproxen-group patients developed ulcers: five had ulcer pain and one developed ulcer bleeding. Only three (7%) patients on triple therapy had ulcers, and two of these patients had failure of H pylori eradication (p = 0.01). Thus, 12 (26%) patients with persistent H pylori infection but only one (3%) with successful H pylori eradication developed ulcers with naproxen (p = 0.002). INTERPRETATION: Eradication of H pylori before NSAID therapy reduces the occurrence of NSAID-induced peptic ulcers.  相似文献

OBJECTIVE: To determine whether 1-day postoperative hospitalization after carotid endarterectomy is safe and the degree to which this can be achieved. DESIGN: Consecutive sample series of all carotid endarterectomies performed by a single surgical group. SETTING: A single tertiary-care hospital. PATIENTS: All who underwent carotid endarterectomy. Patients with procedures combined with coronary revascularization and patients undergoing the first part of a staged bilateral carotid endarterectomy performed in 1 hospitalization were excluded. INTERVENTION: In December 1993, a fast-track protocol was initiated, aiming for a 1-day stay after carotid endarterectomy without admission to an intensive care unit (ICU). Before this date, postoperative care included obligatory monitoring for at least 1 night in an ICU. MAIN OUTCOME MEASURES: Length of stay, admission to and stay in the ICU, complications, and hospital readmission rate. RESULTS: Over a 21-month period, 152 patients had 163 carotid endarterectomies. Of these, 124 were elective and 39 urgent (patients with a critical stenosis). Indications were stroke (n = 14 [8.6%]), transient ischemic attack (n = 50 [30.7%]), amaurosis fugax (n = 36 [22.1%]), and asymptomatic stenosis (n = 63 [38.7%]). General anesthesia was used for 159 procedures, cervical block for 4. Mean operation time was 2.6 hours. Postoperative stay was 1 day for 82 procedures (50%), 2 days for 49 procedures (30%), 3 days for 12 procedures (7%), and longer for 20 procedures (12%). In the last half of the study, 61% of patients (50/82) were discharged on postoperative day 1 and 87% (71/82) by postoperative day 2. One hundred three patients went to a surgical floor postoperatively. Overall, 60 patients went to the ICU, but only 18 (22%) of the last 82 procedures required ICU admission. The total stay averaged 3.8 days. Twenty-one patients (13%) experienced complications, including 3 deaths within 30 days and 5 neurological deficits. There were 14 early readmissions, but none was attributable to discharge on the first or second postoperative day. CONCLUSIONS: Early discharge home after carotid endarterectomy is safe and efficacious, and obligatory admission to an ICU is not necessary. At least 60% of patients who undergo carotid endarterectomy can have a postoperative stay of 1 day, and more than 80% can be discharged by postoperative day 2. A short postoperative stay is not associated with a significant risk of readmission for complications.  相似文献

OBJECTIVES: Acute bleeding from esophageal varices is a major complication of cirrhosis. Despite the large number of published studies no predictive factors of control of bleeding have been identified. We assessed the clinical and biological factors predictive of bleeding control within the first 2 weeks after a bleeding episode in a homogeneous group of patients enrolled in a large multicenter trial, who underwent a standardized emergency sclerotherapy session. METHODS: 101 patients with cirrhosis were enrolled. All had endoscopy-proven variceal bleeding, and the interval between hematemesis or melena and emergency sclerotherapy was always less than 24 hours. A second sclerotherapy session and other methods for the prevention of rebleeding were allowed after 5 days. RESULTS: Treatment failed in 16 patients after 24 hours and in a total of 33 patients after 15 days. Three of the 17 variables included in multivariate logistic analysis were associated with failure at 24 hours: encephalopathy (P = 0.006, OR = 4.0), blood transfusion prior to sclerotherapy (P = 0.012, OR = 6.2) and previous propranolol therapy (P = 0.022, OR = 4.6). Two variables were associated with failure between 24 hours and day 15 in patients successfully controlled after 24 hours: an interval between the onset of bleeding and sclerotherapy of less than 12 hours (P = 0.010) and blood transfusion (P = 0.018). After 15 days, three variables were associated with failure in a multivariate Cox model: encephalopathy (P = 0.0025, OR = 2.3), time to sclerotherapy (P = 0.022, OR 2.3) and blood transfusion before sclerotherapy (P = 0.0005, OR = 4.0). CONCLUSION: Encephalopathy, the severity of bleeding, assessed in terms of transfusion requirements, and the time between clinically overt bleeding and sclerotherapy are the main predictive factors of failure of the control of bleeding after emergency sclerotherapy for acute bleeding from esophageal varices.  相似文献

Bleeding peptic ulcer is the most important cause of upper gastrointestinal bleeding. Our aim was to compare the effect of anti-Helicobacter therapy with maintenance treatment of H2-receptor antagonist in the prevention of relapses of ulcer and bleeding. Patients with bleeding duodenal or gastric ulcers and H. pylori infection were randomized to receive either a one-week course of triple therapy with bismuth subcitrate, metronidazole, and tetracycline plus ranitidine or a six-week course of ranitidine 300 mg/day. After the ulcers healed, the antibiotic-treated patients were not given any medication, whereas the ranitidine-treated patients continued to receive a maintenance dose of 150 mg/day. One hundred twenty-six patients were randomized to receive anti-Helicobacter therapy and 124 patients to receive long-term ranitidine. H. pylori eradication was achieved in 98.2% in those who received triple therapy and 6.1% in those who received ranitidine (P < 0.0001). At the six-week follow-up, ulcer healing was documented in 88.2% in those who received triple therapy and 86.1% in those who received ranitidine (P = 0.639). Recurrent ulcer developed in nine of the ranitidine-treated patients and three of them presented with recurrent upper gastrointestinal bleeding. One patient in the antibiotic group developed recurrent ulcer without rebleeding (P = 0.01). It is concluded that eradication of H. pylori is sufficient for the prevention of recurrent bleeding ulcers.  相似文献

Haemorrhage from oesophageal varices is a life-threatening event in patients with liver cirrhosis. About 40-80% of patients surviving the first bleeding suffer a recurrence within 1 year. This high recurrence rate substantially contributes to the mortality in patients with liver cirrhosis. Therefore, various treatment regimens in both primary and secondary prophylaxis were studied. Most experience in medical primary prophylaxis was collected with beta-blockers, mainly propranolol. Treating patients with oesophageal varices with propranolol significantly reduces the incidence of first variceal bleeding. However, the effect on mortality is marginal, and primary prophylaxis is generally not recommended in these patients. Several studies support the hypothesis that medical prophylaxis with beta-blockers is more effective in reducing the rate of first oesophageal bleeding in patients with a high risk of haemorrhage, such as those with very large varices with red spots. A score to assess an individual patient's risk of variceal bleeding would be helpful, but until such a score has been validated, no general rule for this treatment decision can be given. In secondary prophylaxis, both beta-blockers and endoscopic therapy (sclerotherapy or ligation of the varices) are effective in lowering the rate of rebleeding. However, the effect on mortality was not significant in most studies. Several studies comparing the efficacy of medical prophylaxis and endoscopic treatment showed advantages of the endoscopic therapy with a greater reduction in recurrent bleeding episodes. However, medical prophylaxis with beta-blockers has the important advantage of being immediately effective, whereas endoscopic procedures provide the best protection against recurrent bleeding after complete obliteration of the varices. Therefore, in the first weeks and months of endoscopic therapy, additional treatment with beta-blockers may further reduce the risk of rebleeding. Only half of all studies on this topic reported a significant advantage with this combined therapy. Therefore, it seems reasonable to restrict this approach to patients with a high risk of rebleeding, such as patients with large sclerotherapy-derived oesophageal ulcers.  相似文献

The mortality rate of peptic ulcer haemorrhage has remained unchanged, mainly attributed to rebleeding in an increasingly elderly population with more coexisting systemic diseases. The value of clinical factors and endoscopic findings in predicting in-hospital further haemorrhage and death are analysed. Over a 2-year period, 157 consecutive patients were admitted with bleeding from peptic ulcer, 19 died and 37 had further bleeding. The predictive value of each factor was determined by the chi 2 test with a Yates-correction (significant, p < 0.05). Significant predictive factors of further bleeding were shock, a transfusion requirement > 4 units during the first 48 hours and endoscopic stigmata of recent haemorrhage. The combination of these factors was not of better predictive value than shock alone. The number of coexisting illnesses per patient was strongly related to fatality rate. Other significant factors indicative of an increased mortality included steroid, onset of bleeding during a hospital stay, alcohol, further bleeding, and > 4 units transfused over the first 48 hours. Shock remains the most valuable sign in predicting further bleeding and is superior to endoscopic stigmata. The close relationship between the mortality rate and coexisting illnesses underlines the fact that the majority of deaths result from non peptic ulcer disease.  相似文献

BACKGROUND: The impact of upper endoscopy in patients with upper gastrointestinal hemorrhage treated in community practice is unknown. Thus we examined the effectiveness of endoscopy performed within 24 hours of admission (early endoscopy). METHODS: Medical records of 909 consecutive hospitalized patients with upper gastrointestinal hemorrhage who underwent endoscopy at 13 hospitals in a large metropolitan area were reviewed. We evaluated unadjusted and severity-adjusted associations of early endoscopy with recurrent bleeding or surgery to control hemorrhage, length of hospital stay, and associations of endoscopic therapy in patients with bleeding ulcers or varices. RESULTS: Early endoscopy was performed in 64% of patients and compared with delayed endoscopy and was associated with clinically significant reductions in adjusted risk of recurrent bleeding or surgery (odds ratio [OR] 0.70: 95% CI [0.44, 1.13]) and a 31% decrease in adjusted length of stay (95% CI: [24%, 37%]). In patients at high risk for recurrent bleeding, the use of early endoscopic therapy to control hemorrhage was associated with reductions in recurrent bleeding or surgery (OR 0.21: 95% CI [0.10, 0.47]) and length of stay (-31%: 95% CI [-44%, -14%). CONCLUSION: In this study of community-based practice, the routine use of endoscopy, and in selected cases endoscopic therapy, performed early in the clinical course of patients with upper gastrointestinal hemorrhage was associated with reductions in length of stay and, possibly, the risk of recurrent bleeding and surgery.  相似文献

In cirrhotic patients with gastrointestinal hemorrhage, bacterial infections are frequent and play a significant role in mortality. We have previously found that patients with a Child-Pugh's class C or a rebleeding are a subgroup of cirrhotic patients with a high risk of infection. The aims of the study were (1) to validate these indicators and (2) to assess the effectiveness of a systemic antibiotic treatment in preventing bacterial infections in bleeding cirrhotics with a high risk of infection. One hundred and nineteen bleeding cirrhotic patients were divided into 3 groups. Patients with a Child-Pugh's class A-B and no rebleeding (i.e., with a low risk of infection) constituted group 1 (n = 55). Patients with a high risk of infection were randomly allocated to serve as controls (group 2, n = 34) or to receive the ciprofloxacin and a combination of amoxicillin and clavulanic acid for 3 days after hemorrhage (group 3, n = 30). This antibiotic prophylaxis was administered first intravenously and then orally when the bleeding was controlled. The study period was defined as 10 days after hemorrhage. Incidence of bacterial infections was significantly higher in patients from group 2 than in patients from group 1 (52.9% vs. 18.2%; P < .001). Moreover, infections were more severe in group 2: a sepsis syndrome or a septic shock developed in 66.7% of infected patients from this group, but in only 20% of infected patients from group 1. Incidence of bacterial infections was much lower in patients from group 3 than in those from group 2 (13.3% vs. 52.9%; P < .001). Eight patients from group 2 (23.5%) and 4 patients from group 3 (13.3%) died during the first four weeks (P-not significant). Septic shock was the cause of death in 3 patients from group 2 and in only 1 patient from group 3. The cost of antibiotic therapy, including antibiotic prophylaxis in group 3, was $208 +/- $63 per patient in group 2 and $167 +/- $42 per patient in group 3 (P < .05). We conclude that (1) patients with a Child-Pugh's class C and/or a rebleeding are a subgroup of cirrhotic patients with a high risk of infection after gastrointestinal hemorrhage and that (2) in these patients, a prophylactic treatment with systemic antibiotics is very effective in preventing bacterial infections.  相似文献

Nonsurgical reduction of portal hypertension by transjugular intrahepatic portosystemic shunt (TIPS) is widely used for prevention of variceal rebleeding (elective TIPS). Information is limited about the value of emergency TIPS for acute variceal bleeding unresponsive to endoscopic and drug therapy. The aim of the present study was therefore to determine whether the effects and complications differ between emergency and elective TIPS in patients with cirrhosis of the liver. TIPS was performed in 11 patients with acute variceal bleeding unresponsive to endoscopic treatment and 22 patients in stable condition after an episode of variceal bleeding. Clinical examination, blood sampling, Doppler sonography of TIPS flow, and upper gastrointestinal endoscopy were performed at days 1, 7, and 30 and at three-month intervals after TIPS. Mean follow-up was 549 (1-987) days. Bleeding was controlled by emergency TIPS in 10/11 patients. Probability of survival was not different after emergency and elective TIPS (0.73 vs 0.84 at one year). Early rebleeding (< or =2 weeks) occurred more often after emergency TIPS (3/11 vs 0/22 patients; P = 0.03), but there was no significant difference in late rebleeding. Occlusion of TIPS was more frequent after emergency TIPS. Occurrence of TIPS stenoses was identical in both groups (4/11 vs 8/22). De novo or deterioration of preexisting hepatic encephalopathy was similar (18% vs 24%; NS). It is concluded that TIPS is effective for control of acute variceal bleeding unresponsive to endoscopic and drug treatment. Early rebleeding and stent occlusion occurred more often after emergency TIPS. Late rebleeding, complications, and long-term survival did not differ from elective TIPS.  相似文献

OBJECTIVE: To study long and short term survival in patients aged 60 years or over admitted with a peptic ulcer bleeding and find out which factors influence outcome. DESIGN: Cohort study with matched controls. SETTING: Two emergency hospitals, Sweden PATIENTS: 676 of the 687 patients aged 60 years or over admitted to the two emergency hospitals serving Gothenburg, Sweden during 1989-1993 who fulfilled the diagnostic criteria and whose case notes were available for study. MAIN OUTCOME MEASURES:Seven year survival rates and odds ratios for risk factors based on multiple logistic regression analyses. RESULTS: 37 patients died and the timing was evenly distributed within the first 30 days of admission with a cumulated case-fatality rate of 5.5% at day 30. Mortality was increased among the patients compared with the control group during the subsequent years. Factors that influenced day 30 mortality were age and Forrest class. CONCLUSION: Mortality is increased among patients with peptic ulcer bleeding even long after the event. Old age and signs of recent haemorrhage increase the risk.  相似文献

INTRODUCTION AND OBJECTIVES: The high demand for health care has obliged Coronary Units to hasten the discharge of patients in less serious condition and this might be an influence on their prognosis. Our objective have been: a) to analyse the characteristics and the evolution (death or readmission) during the first month of patients with myocardial infarction and very early discharge from the Coronary Unit (stay of 2 days or less), and b) to assess the profile of very low risk group patients for complications who could be discharged early from the Coronary Unit. PATIENTS AND METHODS: A study of 978 consecutive patients who had been admitted for acute myocardial, in faration were divided into two groups according to their length of stay in the Coronary Unit (A < or = 2 and B > 2 days). Their baseline characteristics, course of stay and vital status at month, were compared. A subgroup of patients at low risk was studied and complications that might have arisen from their early discharge from the Coronary Unit were assessed. RESULTS: Seventy-three patients (7.5%) died within the first two days. Of the remaining 905, the stay was 2 days or less for 336 patients (group A); and longer than 2 days for 569 (group B). Group A had a higher frequency of dyslipemia, Killip class I on admission, uncomplicated myocardial infarction in the Coronary Unit and the use of beta-blockers and had less frequency of diabetes, Q wave myocardial infarction, anterior infarction or the use of fibrinolytics. In the first month after discharge from the Coronary Unit, 10 patients from group A and 18 patients from group B died, the rate of death or readmission into the Coronary Unit within 30 days was similar between both groups (group A = 13% and group B = 13%). A multiple regression showed that Killip class on admission (p < 0.001) and an uncomplicated course (p < 0.001) were independently related with the length of stay in the coronary unit. A subset of 378 low risk patients (Killip I on admission, uncomplicated course in the ICU and age < 71 years) had no mortality at 30 days and their readmission rate in the first month was 4%. In this subgroup, those patients whose stay was equal to or less than two days were more frequently readmitted in the first week. (group A = 9/197 [5%] and group B = 1/181 ([0.5%]; p = 0.034). CONCLUSION: Selected patients with myocardial infarction can be discharged very early from the Coronary Unit with a low risk of death. A readmission rate following discharge of some 5% must be allowed for these patients.  相似文献

Twelve consecutive patients admitted for bleeding from ruptured gastric varices were treated with transjugular intrahepatic portosystemic shunts and followed for a mean of 6 +/- 3 months (range: 8-293 days). The shunt was performed successfully in all 12 patients. The shunt occluded in 3 patients (respectively 19, 101 and 103 days after insertion) of whom one remained asymptomatic and two experienced rebleeding. Four patients presented with acute encephalopathy, spontaneously in two and after rebleeding in two. Three patients died, two after rebleeding and one of septic shock secondary to pneumonia. Overall, 9 patients survived a mean of 211 +/- 92 days with no rebleeding, 8 of whom have not yet experienced any complications. These results suggest that transjugular intrahepatic portosystemic shunts could be useful in treating hemorrhages from ruptured gastric varices and in preventing their recurrence.  相似文献

OBJECTIVE: To evaluate whether the addition of bismuth subnitrate to a dual oral therapy regimen with omeprazole plus amoxycillin could improve Helicobacter pylori eradication. METHODS: Fifty consecutive Helicobacter pylori-positive patients were randomly enrolled to receive either (A) bismuth subnitrate (300 mg q.d.s.), omeprazole (20 mg b.d.) and amoxycillin (500 mg q.d.s.), or (B) omeprazole (20 mg b.d.) and amoxycillin (500 mg q.d.s.). Both groups (n=25 each) received the medication for 14 days. H. pylori status was reassessed 30 days after completion of the therapy in order to evaluate eradication rates. RESULTS: Six patients were lost to follow-up and therefore excluded from the study (three patients from each group). One patient from Group B withdrew from the study because of side-effects. The addition of bismuth subnitrate to omeprazole and amoxycillin significantly improved its efficacy in eradicating H. pylori, with 72% (18/25) eradication in Group A and 52% (13/25) in Group B (P=0.027). The addition of bismuth subnitrate to dual oral therapy was also capable of improving the healing of peptic ulcers when compared with dual oral therapy alone (100%, 8/8 vs. 58%, 4/7; P=0.021). CONCLUSION: Our results demonstrate that the addition of bismuth subnitrate to dual oral therapy enhances H. pylori eradication, and improves healing of peptic ulcers.  相似文献
