BACKGROUND & AIMS Patients with Barrett's esophagus (BE) and high-grade dysplasia (HGD) or early neoplasia increasingly receive endoscopic mucosal resection and radiofrequency ablation (RFA) therapy. We analyzed data from a UK registry that follows the outcomes of patients with BE who have undergone RFA for neoplasia. METHODS We collected data on 335(More)
Barrett's esophagus is an increasingly common disease that is strongly associated with reflux of stomach acid and usually a hiatus hernia, and it strongly predisposes to esophageal adenocarcinoma (EAC), a tumor with a very poor prognosis. We report the first genome-wide association study on Barrett's esophagus, comprising 1,852 UK cases and 5,172 UK(More)
Radiotelemetric ambulatory 24 hour oesophageal pH measurement was carried out in 17 patients with symptomatic manometrically proven achalasia before and after pneumatic dilatation. Before dilatation an abnormally high percentage acid exposure time was present but typical episodes of gastro-oesophageal reflux occurred in only one patient. In nine patients(More)
BACKGROUND Screening Barrett's oesophagus is controversial owing to a large variation in the reported incidence of neoplastic change and lack of evidence that screening improves tumour prognosis. AIMS To determine the incidence of Barrett's cancer, its cost of detection, and stage of disease at time of diagnosis. PATIENTS AND METHODS Data from our(More)
BACKGROUND The outcome of pancreatic resection for chronic pancreatitis in patients with preoperative opioid use is not well described. METHODS During 1997 to 2003, 112 of 231 patients referred with chronic pancreatitis underwent pancreatic resection. The outcome of patients who had preoperative opioid use (N=46) was compared with those without (N=66). (More)
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(More)
Twenty four hour intragastric acidity was measured in five duodenal ulcer patients studied at least three times. The effects of different dosage regimens of intravenous omeprazole was compared with placebo. Mean intragastric acidity from 1000 to 0800 was 34.3 +/- 4.3 mmol/l on placebo. After omeprazole 80 mg at 0900 and 40 mg at 1700 mean acidity was 2.1(More)
The frequency and importance of gastric mucosal lesions in patients with portal hypertension have been increasingly recognized in recent years. This article describes the clinical and endoscopic features of portal hypertensive gastropathy and reviews the current state of knowledge concerning the pathophysiology and treatment of the disorder.
