Randomised comparison between adrenaline injection alone and adrenaline injection plus heat probe treatment for actively bleeding ulcers.

OBJECTIVE: To compare endoscopic adrenaline injection alone and adrenaline injection plus heat probe for the treatment of actively bleeding peptic ulcers. DESIGN: Randomised prospective study of patients admitted with actively bleeding peptic ulcers. SETTING: One university hospital. SUBJECTS: 276 patients with actively bleeding ulcers detected by endoscopy within 24 hours of admission: 136 patients were randomised to endoscopic adrenaline injection alone and 140 to adrenaline injection plus heat probe treatment. MAIN OUTCOME MEASURES: Initial endoscopic haemostasis; clinical rebleeding; requirement for operation; requirement for blood transfusion; hospital stay, ulcer healing at four weeks; and mortality in hospital. RESULTS: Initial haemostasis was achieved in 131/134 patients (98%) who received adrenaline injection alone and 135/136 patients (99%) who received additional heat probe treatment (P = 0.33). Outcome as measured by clinical rebleeding (12 v 5), requirement for emergency operation (14 v 8), blood transfusion (2 v 3 units), hospital stay (4 v 4 days), ulcer healing at four weeks (79.1% v 74%), and in hospital mortality (7 v 8) were not significantly different in the two groups. In the subgroup of patients with spurting haemorrhage 8/27 (29.6%; 14.5% to 50.3%) patients from the adrenaline injection alone group and 2/31 (6.5%; 1.1% to 22.9%) patients from the dual treatment group required operative intervention. The relative risk of this was lower in the dual treatment group (0.17; 0.03 to 0.87). Hospital stay was significantly shorter in the dual treatment group than the adrenaline injection alone group (4 v 6 days, P = 0.01). CONCLUSION: The addition of heat probe treatment after endoscopic adrenaline injection confers an advantage in ulcers with spurting haemorrhage.     

Randomised trial of endoscopy with testing for Helicobacter pylori compared with non-invasive H pylori testing alone in the management of dyspepsia

ObjectiveTo compare the efficacy of non-invasive testing for Helicobacter pylori with that of endoscopy (plus H pylori testing) in the management of patients referred for endoscopic investigation of upper gastrointestinal symptoms.DesignRandomised controlled trial with follow up at 12 months.SettingHospital gastroenterology unit.Participants708 patients aged under 55 referred for endoscopic investigation of dyspepsia, randomised to non-invasive breath test for H pylori or endoscopy plus H pylori testing.ResultsIn 586 patients followed up at 12 months the mean change in dyspepsia score was 4.8 in the non-invasive H pylori test group and 4.6 in the endoscopy group (95% confidence interval for difference –0.7 to 0.5, P=0.69). Only 8.2% of patients followed up who were randomised to breath test alone were referred for subsequent endoscopy. The use of non-endoscopic resources was similar in the two groups. Reassurance value, concern about missed pathology, overall patient satisfaction, and quality of life were similar in the two groups. The patients found the non-invasive breath test procedure less uncomfortable and distressing than endoscopy with or without sedation. No potentially serious pathology requiring treatment other than eradication of H pylori was missed.ConclusionIn this patient group, non-invasive testing for H pylori is as effective and safe as endoscopy and less uncomfortable and distressing for the patient. Non-invasive H pylori testing should be the preferred mode of investigation.

What is already known on this topic

Endoscopy is a commonly used investigation for upper gastrointestinal symptoms, but its effectiveness has been questionedNon-invasive testing for Helicobacter pylori has been shown to predict endoscopic diagnosis in patients with dyspepsia

What this study adds

In patients less than 55 years of age with uncomplicated dyspepsia, non-invasive testing for H pylori is as effective and as safe as endoscopyNon-invasive H pylori testing is as reassuring to the patient as endoscopy and is less uncomfortable and distressing     

Randomised controlled trial of Helicobacter pylori testing and endoscopy for dyspepsia in primary care

ObjectiveTo determine the cost effectiveness of a strategy of near patient Helicobacter pylori testing and endoscopy for managing dyspepsia.DesignRandomised controlled trial.Setting31 UK primary care centres.Participants478 patients under 50 years old presenting with dyspepsia of longer than four weeks duration.InterventionsNear patient testing for H pylori and open access endoscopy for patients with positive results. Control patients received acid suppressing drugs or specialist referral at general practitioner''s discretion.Results40% of the study group tested positive for H pylori. 45% of study patients had endoscopy compared with 25% of controls. More peptic ulcers were diagnosed in the study group (7.4% v 2.1%, P=0.011). Paired comparison of symptom scores and quality of life showed that all patients improved over time with no difference between study and control groups. No significant differences were observed in rates of prescribing, consultation, or referral. Costs were higher in the study group (£367.85 v £253.16 per patient).ConclusionsThe test and endoscopy strategy increases endoscopy rates over usual practice in primary care. The additional cost is not offset by benefits in symptom relief or quality of life.

What is already known on this topic

Patients younger than 50 without H pylori infection are unlikely to have treatable disease detected at endoscopySuch patients can be managed by acid suppression and reassurance aloneTest and endoscopy (referral of patients testing positive for H pylori in primary care) has been recommended as a way to reduce endoscopic workload

What this paper adds

Applying a test and endoscopy strategy increased the endoscopy referral rate from 25% to 40%The strategy produced no significant differences in symptoms or quality of life compared with usual managementThe increased costs of this strategy cannot be justified     

Patient initiated outpatient follow up in rheumatoid arthritis: six year randomised controlled trial

Objectives To determine whether direct access to hospital review initiated by patients with rheumatoid arthritis would result in improved clinical and psychological outcome, reduced overall use of healthcare resources, and greater satisfaction with care than seen in patients receiving regular review initiated by a rheumatologist.Design Two year randomised controlled trial extended to six years.Setting Rheumatology outpatient department in teaching hospital.Participants 209 consecutive patients with rheumatoid arthritis for over two years; 68 (65%) in the direct access group and 52 (50%) in the control group completed the study (P = 0.04).Main outcome measures Clinical outcome: pain, disease activity, early morning stiffness, inflammatory indices, disability, grip strength, range of movement in joints, and bone erosion. Psychological status: anxiety, depression, helplessness, self efficacy, satisfaction, and confidence in the system. Number of visits to hospital physician and general practitioner for arthritis.Results Participants were well matched at baseline. After six years there was only one significant difference between the two groups for the 14 clinical outcomes measured (deterioration in range of movement in elbow was less in direct access patients). There were no significant differences between groups for median change in psychological status. Satisfaction and confidence in the system were significantly higher in the direct access group at two, four, and six years: confidence 9.8 v 8.4, 9.4 v 8.0, 8.7 v 6.9; satisfaction 9.3 v 8.3, 9.3 v 7.7, 8.9 v 7.1 (all P < 0.02). Patients in the direct access group had 38% fewer hospital appointments (median 8 v 13, P < 0.0001).Conclusions Over six years, patients with rheumatoid arthritis who initiated their reviews through direct access were clinically and psychologically at least as well as patients having traditional reviews initiated by a physician. They requested fewer appointments, found direct access more acceptable, and had more than a third fewer medical appointments. This radical responsive management could be tested in other chronic diseases.     

Upper gastrointestinal haemorrhage in patients over 80 years-old

Objectives

To evaluate the patient characteristics, outcome, and prognosis of upper gastrointestinal haemorrhage in the elderly.

Material and methods

A prospective study was conducted on 103 patients aged 80 years and over, admitted to a Gastrointestinal Bleeding Unit after an episode of upper gastrointestinal bleeding. We analysed the personal history, the characteristics of the bleeding event, and whether an urgent diagnostic or therapeutic endoscopy was performed, in order to identify clinical data and endoscopic findings that may have an influence on the outcome of the haemorrhage.

Results

The major cause of the haemorrhage was peptic ulcer in 65.1%, and 60.2% of patients were on chronic treatment with non-steroidal anti-inflammatory drugs. An urgent diagnostic endoscopy was performed in all of them, identifying the source of bleeding in 94.2%, and treatment was carried out on 28.2%. The likelihood of rebleeding was 8%, and 4.9% of patients underwent emergency surgery, with an overall mortality rate of 5.8%.

Conclusions

The performance of urgent endoscopy and the application of endoscopic haemostasis are safe and effective in stopping upper gastrointestinal bleeding in the elderly. This has significantly reduced the need for emergency surgery, improving the survival of the bleeding elderly patient and preventing recurrent bleeding.     

Neodymium yttrium aluminium garnet laser photocoagulation for major haemorrhage from peptic ulcers and single vessels: a single blind controlled study.

A prospective single blind controlled trial was performed to assess the efficacy of the neodymium yttrium aluminium garnet laser in the management of patients bleeding from peptic ulcers and single vessels. Over 20 months 184 patients were found at endoscopy to be bleeding from peptic ulcers and single vessels; 130 of these failed to meet the criteria for entry into the study, but their bleeding stopped with conservative management. Forty-five patients entered the study: in all 25 who were bleeding from ulcers with spots the bleeding stopped irrespective of the treatment allocated. Twenty patients were bleeding from arteries. Eight were allocated to placebo treatment, and all later underwent emergency surgery for further haemorrhage. Twelve were allocated to receive laser treatment, and only one of eight who actually received it required surgery (p less than 0.002). It is concluded that laser treatment reduces the incidence of further haemorrhage and the need for emergency surgery, but the technique is difficult and not always applicable.     

Prospective,randomised, double blind trial of prophylaxis with single dose of co-amoxiclav before percutaneous endoscopic gastrostomy

ObjectiveTo determine the efficacy of antibacterial prophylaxis in preventing infectious complications after percutaneous endoscopic gastrostomy.DesignProspective, randomised, placebo controlled, double blind, multicentre study.SettingDepartments of internal medicine at six German hospitals.SubjectsOf 106 randomised adult patients with dysphagia, 97 received study medication, and 84 completed the study. The median age of the patients was 65 years. Most had dysphagia due to malignant disease (65%), and many (76%) had serious comorbidity.InterventionsA single intravenous 2.2 g dose of co-amoxiclav or identical appearing saline was given 30 min before percutaneous endoscopic gastrostomy performed by the thread pull method.ResultsThe incidence of peristomal and other infections within one week after percutaneous endoscopic gastrostomy was significantly reduced in the antibiotic group (8/41 (20%) v 28/43 (65%), P<0.001). Similar results were obtained in an intention to treat analysis. Several peristomal wound infections were of minor clinical significance. After wound infections that required no or only local treatment were excluded from the analysis, antibiotic prophylaxis remained highly effective in reducing clinically important wound infections (1/41 (2%) v 11/43 (26%), P<0.01) and non-wound infections (2 (5%) v 9 (21%), P<0.05).ConclusionsAntibiotic prophylaxis with a single dose of co-amoxiclav significantly reduces the risk of infectious complications after percutaneous endoscopic gastrostomy and should be recommended.

Key messages

• Percutaneous endoscopic gastrostomy for enteral feeding can be associated with substantial rates of infectious complications, notably peristomal wound infection
• Small, single centre studies on prevention of wound infection by antibiotic prophylaxis have given conflicting results
• This prospective, randomised, placebo controlled, double blind, multicentre study showed that a single dose of 2.2 g co-amoxiclav significantly reduced the rate of infection
• The favourable effect of antibiotic prophylaxis included a reduction in the rate of clinically important peristomal wound infection
• Intention to treat analysis indicated a significant reduction in the need for therapeutic antibiotics

     

Efficacy of self monitoring of blood glucose in patients with newly diagnosed type 2 diabetes (ESMON study): randomised controlled trial

Objectives To assess the effect of self monitoring of blood glucose concentrations on glycaemic control and psychological indices in patients with newly diagnosed type 2 diabetes mellitus.Design Prospective randomised controlled trial of self monitoring versus no monitoring (control).Setting Hospital diabetes clinics.Participants 184 (111 men) people aged <70 with newly diagnosed type 2 diabetes referred to the participating diabetes clinics. Major exclusion criteria were secondary diabetes, insulin treatment, previous self monitoring of blood glucose.Interventions Participants were randomised to self monitoring or no monitoring (control) groups for one year with follow-up at three monthly intervals. Both groups underwent an identical structured core education programme. The self monitoring group received additional education on monitoring.Main outcome measures Between group differences in HbA_1c, psychological indices, use of oral hypoglycaemic drugs, body mass index (BMI), and reported hypoglycaemia rates.Results 96 patients (55 men) were randomised to monitoring and 88 (56 men) to control. There were no baseline differences in mean (SD) age (57.7 (11.0) in monitoring group v 60.9 (11.5) in control group) or HbA_1c (8.8 (2.1)% v 8.6 (2.3)%, respectively). Those in the monitoring group had a higher baseline BMI (34 (7) v 32 (6.2)). There were no significant differences between groups at any time point (12 months values given) in HbA_1c (6.9 (0.8)% v 6.9 (1.2)%, P=0.69; 95% confidence interval for difference −0.25% to 0.38%), BMI (33.1 (6.4) v 31.8 (6.0); adjusted for baseline BMI, P=0.32), use of oral hypoglycaemic drugs, or reported incidence of hypoglycaemia. Monitoring was associated with a 6% higher score on the depression subscale of the well-being questionnaire (P=0.01).Conclusions In patients with newly diagnosed type 2 diabetes self monitoring of blood glucose concentration has no effect on glycaemic control but is associated with higher scores on a depression subscale.Trial registration ISRCTN 49814766.

目的:探讨急诊内镜下止血联合生长抑素治疗上消化道出血的疗效。方法:选取了100例上消化道出血患者,按随机数字表法分为两组,对照组(48例)给予常规止血措施,观察组(52例)行急诊内镜下止血联合生长抑素治疗上消化道出血,通过观察并记录两组患者疗效、不同病灶大小的治疗成功率及临床症状改善情况,评估急诊内镜下止血联合生长抑素治疗上消化道出血的疗效。结果:观察组患者治疗有效率88.5%,对照组患者治疗有效率70.8%,观察组治疗有效率高于对照组(P0.05);观察组对不同病变大小止血成功率均高于对照组(P0.05);从止血治疗成功率来看,随着病变大小的增加,止血成功率有所下降,观察组患者住院时间,大便潜血转阴,呕血消失时间均短于对照组(P0.05),并且术后再出血率也低于对照组患者(P0.05)。结论:急诊内镜下止血联合生长抑素对上消化道出血具有良好的治疗效果,能明显改善上消化道出血症状,缩短患者住院时间,但对病变范围较大的上消化道出血,治疗效果有限。     

Discussing randomised clinical trials of cancer therapy: evaluation of a Cancer Research UK training programme

Objective To evaluate a training intervention aimed at improving healthcare professionals'' communication with cancer patients about randomised clinical trials.Design Before and after evaluation of training programme.Setting Members of the National Cancer Research Network, Scottish Trials Network, and the Welsh Cancer Trials NetworkParticipants 101 healthcare professionals (33 clinicians and 68 research nurses).Intervention Four modules delivered by a trained facilitator using videotapes and interactive exercises to cover general issues about discussing randomised clinical trials with patients, problems specific to adjuvant trials, trials with palliation as the goal, and trials where patients had a strong preference for one treatment arm.Main outcome measures Before and after the intervention, participants were videotaped discussing a trial with an actor portraying a patient. These consultations were assessed for presence of information required by good clinical practice guidelines. The actor patients gave an assessment after each interview. Participants reported their self confidence about key aspects of trial discussion.Results Analysis of the videotaped consultations showed that, after intervention, significantly more participants displayed key communication behaviours such as explaining randomisation (69 v 81, odds ratio 2.33, P = 0.033), checking patients'' understanding (11 v 31, odds ratio 3.22, P = 0.002), and discussing standard treatment (73 v 88, odds ratio 4.75, P = 0.005) and side effects (69 v 85, odds ratio 3.29, P = 0.006). Participants'' self confidence increased significantly (P < 0.001) across all areas. Actor patients'' ratings of participants'' communication showed significant improvements for 12/15 key items.Conclusion This intensive 8 hour intervention significantly improved participants'' confidence and competence when communicating about randomised clinical trials.     

Radiology and endoscopy in acute upper gastrointestinal bleeding.

Of 112 patients admitted with acute upper gastrointestinal bleeding, the presumed bleeding site was detected in 61-5% of cases by radiology and in 57% of cases on endoscopy. Thirty-one patients who had barium-meal examination were operated on and the surgical and radiological findings agreed in 26 (84%). Twenty-three patients who had endoscopy were operated on and the surgical and endoscopic findings agreed in 15 (65%). In 10 cases radiology detected a lesion not identified on endoscopy and in nine endoscopy detected a lesion not seen at radiology. We suggest that when there are two potential sources of bleeding radiology as well as endoscopy can detect the actively bleeding lesion. The supplementary nature of radiology and endoscopy is emphasised and we conclude that both methods should be used if there is any doubt at the initial radiological or endoscopic examination about the source of the bleeding.     

Bleeding varices: 1. Emergency management.

The aim of the emergency management of bleeding varices is to stop the hemorrhage nonoperatively if possible, avoiding emergency shunt surgery, an operation that has a higher mortality than elective shunt surgery. Patients with an upper gastrointestinal hemorrhage should undergo endoscopy immediately to verify the diagnosis of bleeding varices. They can then be categorized according to whether they stop bleeding spontaneously (group 1), continue to bleed slowly (group 2) or continue to bleed rapidly (group 3). Group 1 patients are discussed in the second part of this two-part series. Group 2 patients are initially treated with vasopressin given intravenously; those who fail to respond should undergo emergency angiography and receive vasopressin intra-arterially. If this fails, patients at low surgical risk should undergo urgent shunt surgery; those at high risk do better with endoscopic sclerotherapy. Group 3 patients are also given an intravenous infusion of vasopressin. Patients at low surgical risk who continue to bleed then receive tamponade with a Sengstaken--Blakemore tube. If this fails, they undergo emergency creation of an H-shaped mesocaval shunt. Patients at high surgical risk who fail to respond to vasopressin given intravenously are next treated intra-arterially. If this fails they are given either endoscopic or transhepatic sclerotherapy.     

内镜下注射硬化剂治疗食管贲门粘膜撕裂综合症的临床研究

目的:研究内镜下注射1%乙氧硬化醇和注射1:10 0000肾上腺素治疗食管贲门粘膜撕裂综合症的疗效及安全性。方法:按照随机抽样的原则,从行急诊胃镜检查确诊为食管贲门粘膜撕裂综合症并行内镜下止血治疗的患者中,随机抽取58例患者,按随机数字表法分为治疗组29例和对照组29例,治疗组采用内镜下注射1%乙氧硬化醇,对照组采用内镜下注射1:10 0000肾上腺素,观察两组患者首次止血成功率,早期、近期、远期再出血率,并发症发生率等。结果:治疗组首次止血成功率96.55%(28/29),对照组首次止血成功率93.10%(27/29),两组差异无统计学意义(P>0.05),治疗组早期再出血率7.41%(2/28),显著低于对照组29.63%(8/27)(P<0.05),治疗组近期及远期再出血率为3.57%(1/28),对照组近期及远期再出血率3.70%(1/27),两组差异无统计学意义(P>0.05),两组均无栓塞、穿孔、死亡等并发症出现。结论:内镜下注射乙氧硬化醇治疗食管贲门粘膜撕裂综合症优于注射肾上腺素。     

Omeprazole and cimetidine in the treatment of ulcers of the body of the stomach: a double blind comparative trial. Danish Omeprazole Study Group.

OBJECTIVE--To see whether omeprazole was superior to cimetidine in healing ulcers of the body of the stomach. DESIGN--Double blind randomised parallel group study of omeprazole versus cimetidine for six weeks with assessment of healing at end of every second week. SETTING--Outpatient referrals in 11 centres in Denmark. PATIENTS--One hundred sixty one patients who satisfied the following criteria: age 18-79; one or more ulcers of body of stomach (that is, at or above the angulus) seen endoscopically within four days before study treatment; no H2 receptor antagonists taken within previous two weeks; no history of gastric surgery and no complications needing surgery; no concurrent treatment or disease that might confound assessment; oral contraception or an intrauterine device being used by women of childbearing age. INTERVENTIONS--Omeprazole 30 mg daily (one capsule in the morning) or cimetidine 1 g daily (one 200 mg tablet thrice daily, two tablets at bedtime) for six weeks. Inactive capsules and tablets provided so that all patients took same number of capsules and tablets daily. Compliance monitored by pill counts. END POINT--Endoscopic evidence of accelerated healing of type I gastric ulcers after four weeks of omeprazole. MEASUREMENTS AND MAIN RESULTS--Pain recorded on diary cards and patients assessed after two, four, and six weeks of treatment for clinical state and by endoscopy and biopsy and repeat laboratory tests. Twenty eight patients withdrawn during trial for violations of protocol. At two weeks healing rates were identical in the two treatment groups (omeprazole 41% (30/73 patients); cimetidine 41% (30/73]. At four weeks cumulative healing rates were 77% (53/69 patients) in the omeprazole treatment group and 58% (41/71) in the cimetidine treatment group (95% confidence interval of difference between groups 4% to 34%). By six weeks the cumulative healing rates in the two treatment groups differed by only 6% (60/68 patients (88%) given omeprazole; 53/65 (82%) given cimetidine). Log rank analysis with ulcer size used as covariable showed a significant difference in healing times in favour of omeprazole. There was no difference in the occurrence of pain relief between the two treatment groups. No serious clinical or biochemical side effects of treatment were noted. CONCLUSIONS--Omeprazole 30 mg daily accelerates healing of ulcers in the body of the stomach as compared with cimetidine 1 g daily. This effect is more pronounced in ulcers greater than 12 mm diameter.     

经胸前壁入路内镜甲状腺手术与传统甲状腺手术的 对照研究

目的:通过临床非随机性对照研究,比较经胸前壁入路内镜甲状腺手术与传统甲状腺手术在手术时间、术中出血量、术后引流量、术后疼痛、功能恢复、术后住院时间、住院费用及美容效果上的不同,探讨经胸前壁入路内镜甲状腺手术的可行性及临床效果。方法:回顾性分析86例甲状腺手术,其中46例患者采用经胸前壁入路内镜甲状腺手术的患者为内镜组,40例行传统甲状腺手术为传统组。结果:两组患者均顺利完成手术,术后恢复良好,均未发生术后大出血、喉返神经、喉上神经及甲状旁腺损伤等并发症。两组患者的术后住院时间及术后引流量无显著差异。与传统组比较,内镜组手术时间明显延长(P<0.05),术中出血量明显减少(P<0.05),术后疼痛明显降低(P<0.05),功能恢复即术后自行下床洗漱时间明显缩短(P<0.05),住院费用显著增加(P<0.05),手术美容效果满意度明显提高(P<0.05)。结论:相对传统甲状腺手术,经胸前壁入路内镜甲状腺手术具有切口小、出血量少、术后疼痛轻、功能恢复快、美容满意度高等优点,是治疗甲状腺疾病安全、有效的手术方法。     

Double blind randomised controlled trial of effect of metoprolol on myocardial ischaemia during endoscopic cholangiopancreatography.

OBJECTIVE--To evaluate the effect of metoprolol, a beta adrenergic blocking drug, on the occurrence of myocardial ischaemia during endoscopic cholangiopancreatography. DESIGN--Double blind, randomised, controlled trial. SETTING--University Hospital. SUBJECTS--38 (two groups of 19) patients scheduled for endoscopic cholangiopancreatography. INTERVENTIONS--Metoprolol 100 mg or placebo as premedication two hours before endoscopy. MAIN OUTCOME MEASURES--Heart rate, arterial oxygen saturation by continuous pulse oximetry, ST segment changes during endoscopic cholangiopancreatography (an ST segment deviation > 1 mV was defined as myocardial ischaemia), electrocardiogram monitored continuously with a Holter tape recorder. RESULTS--All patients had increased heart rate during endoscopy compared with rate before endoscopy, but heart rate during endoscopy was significantly lower in the metoprolol group compared with the placebo group (P = 0.0002). Twenty one patients (16 placebo, 5 metoprolol; P = 0.0008) developed tachycardia (heart rate > 100/min) during the procedure, and 11 patients (10 placebo, 1 metoprolol; P = 0.003) developed myocardial ischaemia. One patient in the placebo group had an acute inferolateral myocardial infarction. In the 10 other patients with signs of myocardial ischaemia during endoscopy the ST deviation disappeared when the endoscope was retracted. In all patients myocardial ischaemia was related to increases in heart rate, and 10 of the 11 patients had tachycardia coherent with myocardial ischaemia. CONCLUSIONS--Metoprolol prevented myocardial ischaemia during endoscopic cholangiopancreatography, probably through lowering the heart rate. Thus, tachycardia seems to be a key pathogenic factor in the development of myocardial ischaemia during endoscopy.     

Outcome of endoscopy and barium radiography for acute upper gastrointestinal bleeding: controlled trial in 1037 patients.

A study was conducted to find whether the higher diagnostic yield of endoscopy compared with barium radiography improves management or survival in patients with acute upper gastrointestinal bleeding. A total of 1037 patients were entered into a randomised study comparing the outcomes after each investigation. The diagnostic yield in patients who underwent endoscopy was 73% (382 of 526 cases) and in those examined by radiography 55% (280 of 511 cases). A fifth of the patients in the radiology group and a tenth of those in the endoscopy group subsequently underwent the alternative investigation; in most cases, however, no additional diagnostic information was obtained. Operation rates were similar in two groups, though patients in the endoscopy group were generally operated on sooner. Mortality rates were also similar in the two groups, though postoperative mortality was higher in the endoscopy group. Endoscopy may be a more accurate means of diagnosis than radiography, but it offers no short-term benefits in management.

15例Dieulafoy病的内镜下诊断及治疗

目的:探讨消化道内窥镜对于胃Dieulafoy病的诊断和治疗作用。方法:对山东省立医院近3年收治的15例Dieulafoy病的临床资料进行回顾性分析。结果:13例内镜下止血治疗成功,无再出血(随访时间为12个月到36个月);1例内镜下治疗后再次出血,给予第二次内镜治疗后,随访18个月未再出血;1例因患者家属商议后坚持行外科手术治疗(近端胃切除术)。结论:内镜下治疗可作为处理胃Dieulafoy病的首选方案,仔细而谨慎的内镜下操作有助于提高胃Dieulafoy病的诊断。     

不同术式经皮椎间孔镜治疗腰椎间盘突出症的疗效分析

目的:探讨不同术式经皮椎间孔镜治疗腰椎间盘突出症的疗效。方法:选取我院2013年9月~2015年7月我院收治的采用经皮椎间孔镜治疗的腰椎间盘突出症患者159例,根据不同手术方式进行分组,其中采用YESS手术的36例患者作为YESS组,采用TESSYS手术的76例患者作为TESSYS组,采用BEIS手术(即改良的TESSYS手术)的47例患者作为BEIS组。于术前、术后1天、3个月、6个月、12个月对所有患者进行视觉疼痛模拟评分(VAS)和改良的MacNab疗效评定。结果:三组的手术时间、术中出血量、住院时间比较差异有统计学意义(P0.05),BEIS组和TESSYS组的手术时间、术中出血量高于YESS组,且BEIS组手术时间、术中出血量高于TESSYS组,BEIS组的住院时间高于YESS组和TESSYS组,差异均有统计学意义(P0.05)。三组患者术后各时期VAS评分均较术前降低(P0.05),但三组间术前、术后不同时期VAS评分整体比较均无统计学差异(P0.05)。三组优良率整体比较,差异无统计学意义(P0.05)。结论:不同术式经皮椎间孔镜治疗腰椎间盘突出症的疗效相当,可以有效减轻术后患者的疼痛,但是三种术式的手术时间、术中出血量、住院时间有所差异,临床上针对不同类型的腰椎间盘突出症应采用不同术式,以获得更确切的疗效。
