SUMMARY Of one hundred and twenty-one patients with neoplastic obstruction of the oesophagus or cardia 118 underwent palliative intubation at fibreoptic endoscopy on a total of 135 occasions. Sixty had adenocarcinoma, 49 had squamous carcinoma, and in nine the oesophagus was involved by a growth arising elsewhere. Satisfactory swallowing was restored in 112 patients. Thirteen patients died in hospital shortly after the procedure. Five fatal and 10 non-fatal perforations were sustained in 135 intubation procedures. Complications of tube function included food blockage on 26 occasions, tumour overgrowth on seven occasions, displacement on 16 occasions, disappearance of the tube in two patients, and late oesophageal perforation on nine occasions. Fifty-six patients survived for three months, 33 for six months, and 10 for a year after intubation. Comparison with series in the literature of patients who underwent surgical palliative intubation suggests that endoscopic palliation has lower mortality and morbidity, and an increased survival time, and is now the method of choice for palliation of oesophagogastric neoplasms.Carcinomas of the oesophagus and gastric cardia cause progressive dysphagia and, in the absence of treatment, starvation is a common cause of death. Surgically incurable disease is present in over 60%of patients at the time of presentation' and in the majority of these patients palliative relief of dysphagia is of pressing importance. Any method of palliation should therefore have a low mortality and morbidity, preferably associated with a short hospital stay, and be effective in the relief of dysphagia. For many years prosthetic oesophageal tubes inserted either by operation or endoscopic means have been used to relieve dysphagia,2-5 but operative methods require a laparotomy and rigid endoscopic methods may be associated with a high incidence of oesophageal perforations, especially with lesions in the lower oesophagus. The advent of fibreoptic endoscopy has facilitated the placement of prosthetic tubes which may be slid into position over the endoscope itself6 or over a guide wire after mounting on an introducer.7 The quality and duration of life after intubation depend, among * Present address: Gastroenterology Unit,

We studied the effects of tranexamic acid (an antifibrinolytic agent) and cimetidine on acute upper-gastrointestinal-tract bleeding in a double-blind randomized placebo-controlled trial in 775 patients with hematemesis or melena or both. Mortality was significantly reduced in patients receiving either tranexamic acid (mortality, 6.3 per cent) or cimetidine (7.7 per cent), as compared with patients receiving placebo (13.5 per cent) (P = 0.0092 for tranexamic acid vs. placebo, P = 0.045 for cimetidine vs. placebo). Ninety-nine patients were withdrawn before the code was broken, mainly because their primary illness was considered not to be due to acute upper-gastrointestinal-tract bleeding. Mortality among those withdrawn was high (22 per cent), and their exclusion reduced death rates to 4 per cent in those given tranexamic acid, 8 per cent in those given cimetidine, and 11 per cent in those given placebo (P = 0.0072 for tranexamic acid vs. placebo, P greater than 0.50 for cimetidine vs. placebo). The reduced mortality associated with tranexamic acid was detectable at both participating hospitals and in most of the main subgroups of patients classified according to site of bleeding. However, treatment with this agent was not associated with any decrease in the rate of rebleeding or the need for operation.

The use of alternative medicine was assessed by questionnaire in 96 patients with irritable bowel syndrome, 143 patients with organic upper gastrointestinal disorders and 222 patients with Crohn's disease of comparable age and sex. Significantly more patients with the irritable bowel syndrome (16%) had consulted practitioners of alternative medicine about their condition than had patients in either of the other groups. Similarly, significantly more irritable bowel syndrome patients said they would consult an alternative medicine practitioner (41%) if conventional treatment failed. Current usage of alternative medicine remedies was significantly greater in the irritable bowel syndrome patients (11%) than in patients with Crohn's disease (4%) and tended to be greater than in patients with organic upper gastrointestinal disorders (6%). This study has shown that the use of alternative medicine is common in patients with irritable bowel syndrome and this does not appear to be explicable in terms of the nature, chronicity or refractoriness to treatment of symptoms.

Fifty-six patients with Barrett's oesophagus diagnosed between 1977 and 1986 were prospectively studied by 6-monthly endoscopic surveillance and biopsy. During follow-up to-date, four patients have developed high-grade dysplasia and three have adenocarcinoma of the oesophagus. Two of the adenocarcinomas were preceded by progressively severe dysplastic changes but in the third no dysplasia had been previously detected. The incidence of adenocarcinoma was 1 per 56 patient-years of follow-up. Changes in symptomatology or gross endoscopic appearances were usually absent, even after adenocarcinoma had developed, indicating that biopsy is essential for early diagnosis. The high risk of malignant change makes endoscopic surveillance advisable in all patients with Barrett's oesophagus.

Data on sepsis prevalence on the general wards is lacking on the UK and in the developed world. We conducted a multicentre, prospective, observational study of the prevalence of patients with sepsis or severe sepsis on the general wards and Emergency Departments (ED) in Wales. During the 24-hour study period all patients with NEWS≥3 were screened for presence of 2 or more SIRS criteria. To be eligible for inclusion, patients had to have a high clinical suspicion of an infection, together with a systemic inflammatory response (sepsis) and evidence of acute organ dysfunction and/or shock (severe sepsis). There were 5317 in-patients in the 24-hour study period. Data were returned on 1198 digital data collection forms on patients with NEWS≥3 of which 87 were removed, leaving 1111 for analysis. 146 patients had sepsis and 144 patients had severe sepsis. Combined prevalence of sepsis and severe sepsis was 5.5% amongst all in-patients. Patients with sepsis had significantly higher NEWS scores (3 IQR 3–4 for non-sepsis and 4 IQR 3–6 for sepsis patients, respectively). Common organ dysfunctions in severe sepsis were hypoxia (47%), hypoperfusion (40%) and acute kidney injury (25%). Mortality at 90 days was 31% with a median (IQR) hospital free stay of 78 (36–85) days. Screening for sepsis, referral to Critical Care and completion of Sepsis 6 bundle was low: 26%, 16% and 12% in the sepsis group. Multivariable logistic regression analysis identified higher National Early Warning Score, diabetes, COPD, heart failure, malignancy and current or previous smoking habits as independent variables suggesting the diagnosis of sepsis. We observed that sepsis is more prevalent in the general ward and ED than previously suggested before and that screening and effective treatment for sepsis and severe sepsis is far from being operationalized in this environment, leading to high 90 days mortality.
