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.     

Study of Dyspepsia in a General Practice as Assessed by Endoscopy and Radiology

Fifty consecutive patients presenting in a general practice with dyspepsia were studied. Each patient was referred for a combined barium-meal examination and cholecystogram, followed by fibreoptic endoscopy of the oesophagus, stomach, and duodenum. Thirty patients had a specific lesion of the upper digestive tract and a further four had gall-bladder disease; of these, 16 required surgical treatment. Endoscopy in the remaining 16 patients showed nine with mucosal abnormalities, leaving only seven patients to be classified as normal.The advantage of having an endoscopy service to supplement radiological investigation of dyspepsia is shown.     

Open-access endoscopy service for general practitioners.

An open-access general-practitioner referral service for endoscopy of the upper gastrointestinal tract was established in a district general hospital, and the impact of the service over three years was assessed. The reason for referral, duration of symptoms, and amount of disease detected were the same in patients referred by general practitioners and those attending from hospital outpatient departments. Despite a steady increase in the number of patients referred for endoscopy, the number of barium-meal examinations performed did not correspondingly decrease. The number of ulcers and cancers detected in each six-month period of the study did not increase, and the combined overall pick-up rate for these two conditions fell from 25% to 13%. All general practitioners in the area were sent questionnaires. Most thought that clinic referral had been reduced and patient management helped as a result of the introduction of the service. While the value of negative endoscopic findings cannot be assessed, there is little objective evidence of benefit. Hence the large increase in numbers of endoscopies performed as a result of the introduction of the service cannot be justified.     

Natural History of Patients with X-ray-negative Dyspepsia in General Practice

When 102 patients with dyspepsia who had normal findings on barium-meal examination in 1964 were interviewed in 1970, 85 of them (76%) were symptomatically improved, and only three were later shown to have a peptic ulcer. This suggests that “x-ray-negative dyspepsia” has a good prognosis in a general practice setting.     

Colonic Retention of Barium in the Elderly after Barium-meal Examination and its Treatment with Lactulose

Five cases of colonic retention of barium with severe constipation occurring in elderly patients after a barium-meal examination were seen in a two-year period and it is suggested that this complication may be unrecognized. Lactulose 50% (Duphalac) was an effective agent in inducing bowel evacuation in these patients, who were resistant to more generally used methods.     

Absence of Helicobacter pylori in tonsillar swabs from dyspeptic patients

Aim of this study was to evaluate whether tonsils might be a potential reservoir for Helicobacter pylori (H. pylori) infection. A total of 72 consecutive dyspeptic patients undergoing endoscopy for the first time were studied. For each patient, a bilateral tonsillar swab was performed, before endoscopy, for microbiological culture and immunochemical analysis. Antral biopsies were also collected at endoscopy for microbiological culture, rapid urease test, and histological examination. Helicobacter pylori infection was detected in 42 of 72 (58.3%) patients. All tonsillar specimens were negative for H. pylori on both microbiological culture and immunochemical analysis, suggesting that the tonsils are not an extragastric reservoir for H. pylori infection.     

Obscure gastrointestinal haemorrhage of small-bowel origin.

The records of 37 patients investigated for obscure gastrointestinal haemorrhage originating from the small bowel were reviewed retrospectively. Bleeding was caused by Meckel''s diverticula in eight cases, smooth muscle tumours in seven cases, vascular anomalies in 14 cases, and other single lesions in eight cases. The lesions were identified by angiography in 18 patients, operation in 17, and barium follow through examination in two. Only one patient under 50 years of age had a lesion that would not have been found by careful laparotomy. Early laparotomy is advisable in patients aged under 50 with obscure gastrointestinal bleeding; expert selective angiography is recommended before operation in patients aged over 50 and those who have already undergone a laparotomy yielding negative results.

Highly selective vagotomy for duodenal ulcer: do hypersecretors need antrectomy?

Two to five years after highly selective vagotomy (H.S.V.) for duodenal ulcer the results were similar in patients with high preoperative maximal acid outputs and those with lower acid outputs. Pain of ulcer type was experienced at some time by 6% of patients from each group, but it was mild and transient in some. No patients had recurrent ulceration at endoscopy or laparotomy, while incidence of individual symptoms was about equal in the two groups. Hence H.S.V. is adequate surgical treatment for patients with both duodenal ulceration and high levels of acid secretion. Antrectomy in such patients is not necessary provided that the incidence of incomplete vagotomy can be kept low.     

Choice of age cut-off for endoscopy in dyspepsia in developing countries according to incidence of gastric cancer

Endoscopic examination of all patients with dyspepsia is hard to perform, because of high annual prevalence of dyspepsia and limited resource availability, especially in developing countries. Aim was to establish age cut off for upper endoscopy in dyspeptic patients without alarming features according on incidence of gastric cancer in western Herzegovina in Bosnia and Herzegovina. Group of 2697 (1536 males, 1161 females) patients over 15 with chronic dyspepsia without alarming features and symptoms of gastroesophageal reflux disease, had been referred for a diagnostic upper endoscopy during 4 years. Study was prospective. All 34 gastric cancers were diagnosed in male patients above 55 years, and in female ones above 60. In the same age groups two thirds of gastric ulcers were found out. If the age cut off for dyspeptic patients had been 55 years for male and 60 for female gender, the workload could be decreased by 50%. The choice of alternative approaches is possible, depending on the level of diagnostic uncertainty, the patient and his physician are prepared to accept. Age cut off determines diagnostic approach in chronic dyspepsia, and greatly decreases the endoscopy workload.

目的探讨超声内镜和胃镜在胃间质瘤的临床诊断价值。方法选取我院2013年1月~2014年11月初步诊断为胃间质瘤患者350例,其中行超声内镜检查175例,行胃镜检查175例,两组均行镜下病理活检,并比较两组检查结果的阳性率与病理结果之间的诊断符合率。结果超声内镜诊断阳性率为100%(175/175),胃镜诊断阳性率为97.14%(170/175),与病理结果的符合率为超声内镜的诊断符合率97.14%(170/175),高于胃镜诊断符合率的94.29%(165/175),但两者差异无统计学意义(P0.05)。结论超声内镜及胃镜诊断胃间质瘤各有特点,超声内镜诊断率高可作为胃间质瘤的术前首选检查。     

Imprint cytology in the diagnosis of Helicobacter pylori. Does imprinting damage the biopsy specimen?

OBJECTIVE: To investigate the efficacy of imprint cytology in the diagnosis of Helicobacter pylori infection and whether it damages the biopsy specimen for subsequent histologic examination. STUDY DESIGN: Two antral biopsies were taken from 76 patients with dyspeptic symptoms undergoing upper gastrointestinal endoscopy. Imprint cytology was made from the first specimen. This specimen was fixed in 10% formalin and sent for histopathologic examination. The second specimen was directly fixed in 10% formalin for routine histopathologic examination without being used for an imprint. The imprint smears were examined by cytopathologists. The biopsy specimens were examined by pathologists who did not know which specimens were used for the imprints. RESULTS: H pylori was seen in smears from 55 (72%) patients and in both biopsy specimens from the same patients. The pathologists could not recognize the biopsy specimens from which the imprints were made. Concordance between imprint cytology and histopathology was 100%. CONCLUSION: Imprint cytology is a suitable test for H pylori diagnosis, and imprints do not adversely affect the quality of the biopsy specimen.     

Upper gastrointestinal Kaposi's sarcoma in patients positive for HIV antibody without cutaneous disease

Six patients with antibodies to the human immunodeficiency virus (HIV) and with persistent gastrointestinal symptoms of HIV infection but without cutaneous lesions of Kaposi''s sarcoma underwent endoscopy. Four also underwent barium meal examination. In all six cases small lesions were seen in the stomach at endoscopy, and histological examination of biopsy specimens taken from the lesions confirmed the diagnosis of Kaposi''s sarcoma. The barium meal examinations were reported as normal in three patients and showed oesophageal candidiasis in the fourth.These findings suggest that Kaposi''s sarcoma of the upper gastrointestinal tract is common in patients positive for HIV antibody, even those without cutaneous lesions. Endoscopy, with biopsy of suspicious lesions, is necessary to make the diagnosis and is recommended in all HIV antibody positive patients with persistent upper gastrointestinal symptoms.     

Dyspepsia: is a trial of therapy appropriate?

Dyspepsia is a common, benign condition that may be distinguished from gastroesophageal reflux, irritable bowel syndrome and pancreatobiliary, coronary or musculoskeletal disease by a careful history and physical examination. However, the presence or absence of a peptic ulcer in dyspepsia can be determined only by an endoscopic examination or a barium-contrast radiograph. Although the American College of Physicians has recommended trying drug therapy for patients with dyspepsia before diagnostic tests are done, new data support early diagnosis. Although therapy is initially cheaper than endoscopic examination, over a year the costs even out because most patients with dyspepsia eventually need an endoscopic examination, and many patients with nonulcer dyspepsia are given medication unnecessarily. Endoscopic examination, if available to general practitioners, is the most cost-effective approach to dyspepsia. An approach that does not include endoscopy lacks the opportunity to offer patients convincing reassurance that their illness is not serious, which is arguably the most important treatment in cases of nonulcer dyspepsia. Studies supporting the use of endoscopic examination predate the treatment of peptic ulcers with antibiotics, which makes an initial endoscopic examination to determine whether the patient has an ulcer even more important.     

终末期肾病患者合并胃食管反流病的临床研究进展

胃食管反流病(GERD)是最常见的食管疾病之一。多项研究表明,终末期肾病(ERSD)患者GERD的患病率高于普通人群。目前对于ERSD患者特别是血液透析患者GERD的症状特点及严重程度的研究较少。ESRD患者常并发或伴发糖尿病、高血压等,而糖尿病神经病变可影响胃排空功能,钙拮抗剂和硝酸酯类药物可影响LES舒张功能。透析相关淀粉样变通过影响食管蠕动、食管下段括约肌张力和胃排空影响GERD的发生。ERSD患者中,相当比例的患者全身状况不佳,行胃镜风险较高,常常应用标准化量表或质子泵抑制剂诊断试验评估患者症状性GERD患病情况。ESRD及透析患者GERD的知晓率仍较低,部分患者自行服用碳酸氢钠等非一线药物控制症状。理论上对于ESRD及透析患者伴随的GERD进行早期诊断和治疗可能提高患者生活质量,并减少水钠摄入,改善血压及透析间期体重增加,降低心血管事件风险,具体的临床获益仍有待进一步研究证实。     

Culdoscopy

Cul-de-sac puncture for introduction of a culdoscope is easily made with the patient in the knee-chest position. With the use of the instrument, the pelvic organs can be viewed clearly. Culdoscopic examination of 45 patients was carried out. In all cases in which laparotomy was done after the examination, the culdoscopic observations and diagnosis were confirmed. In no case in which tubal pregnancy was present, was the diagnosis missed in culdoscopic examination. Patients were only slightly uncomfortable after the examination. There was no evidence of pelvic peritonitis in any patient, and no pregnant patient aborted as a result of the procedure.     

Response of patients to upper gastrointestinal endoscopy: effect of inherent personality traits and premedication with diazepam.

The influence of personality traits on the reaction of patients to upper gastrointestinal endoscopy was studied prospectively in 86 patients. High N (neuroticism) scores on the Eysenck personality inventory were associated with poor tolerance to and future compliance with the procedure. Although premedication with diazepam did not affect the degree of discomfort and distress during the procedure, it guaranteed acceptance of repeat endoscopy by virtue of its strong amnesic effect. By contrast, not giving premedication to patients who were anxious and had high N scores jeopardized future compliance. These findings suggest that a version of the Eysenck personality inventory should be used to assess patients'' neurotic phenotype and their need for premedication before endoscopy. Alternatively, all patients might be given premedication.

Coyote laparotomy: in vivo determination of reproductive success

Reproductive tracts of 24 female coyotes hand-reared for behavioral research were examined by laparotomy following the 1977-78 breeding season. Litter counts revealed 51 whelps with 10 of the 24 females while examination by laparotomy indicated 83 uterine swellings in 18 of the same 24 females. The laparotomy proved to be an effective, relatively precise procedure and gave a 39% increase in data acquisition.     

Laxative-induced Diarrhoea: A Continuing Clinical Problem

Seven women spent an average of 127 days in hospital and were extensively investigated, including a laparotomy, before their complaints of abdominal pain, diarrhoea, and weight loss were shown to be due to excessive taking of laxatives. All denied taking laxatives and in none were the characteristic features of the effects of cathartics on the colon seen on sigmoidoscopy or radiological examination.Hypokalaemia and other electrolyte abnormalities were common and were thought to be due to a combination of severe diarrhoea and vomiting. The rectal mucosa was seen to be abnormal on biopsy only in the three patients who had taken senna preparations. The diagnosis was not easy and was finally established either by analysis of the urine and stools or by searching the patient''s ward locker.
