BACKGROUND A rapid, reliable, and accurate test for the diagnosis of infection with Helicobacter pylori is needed for screening dyspeptic patients before referral for endoscopy. AIM To compare a new rapid whole blood test (Helisal rapid blood, Cortecs), two serum enzyme linked immunosorbent assays (ELISAs; Helico-G, Shield and Helisal serum, Cortecs), and(More)
A multicentre randomized prospective trial compared minimal surgery (under-running the vessel or ulcer excision and adjuvant ranitidine) with conventional ulcer surgery (vagotomy and pyloroplasty or partial gastrectomy) for the treatment of bleeding peptic ulcer. This report is based on 137 patients (eight withdrawn through misdiagnosis or lost data), of(More)
The effects of intragastric infusion of 10% Intralipid and 10% dextrose on the intraluminal pressures in the antrum, pylorus and duodenal bulb have been examined. Ten studies with each infusate have been performed in 10 normal subjects and the results compared with those obtained previously in 22 studies during intragastric infusion of isotonic saline.(More)
The high incidence of clinical remission after faecal diversion for Crohn's colitis suggests the faecal stream may play a part in the inflammatory mechanism. The effect of faecal diversion (n = 22) and restoration of intestinal continuity (n = 10) was assessed in patients with Crohn's colitis and compared with controls. Faecal diversion produced significant(More)
BACKGROUND Helicobacter pylori eradication for peptic ulcer has been widely taken up. Evidence for the efficacy of different regimens is often derived from small series in clinical trials but there is little reporting of everyday practice with unselected patients. Freedom from ulcer relapse has been demonstrated, but not whether this equates with clinical(More)
Duodenogastric bile reflux (DGBR) is reported to be increased in patients with gastric ulcer (GU) and following Billroth I partial gastrectomy (BIPG). pH, total bacterial counts, and total and free bile acids were measured in gastric juice aspirated hourly for 24 h in 6 patients with GU, 7 patients with a BIPG performed for GU and in 8 healthy normal(More)
Three groups of patients studied after operations which had cured their duodenal ulcer were compared with a control group (no operation, n = 8). The surgical procedures included: proximal gastric vagotomy (n = 7), truncal vagotomy and pyloroplasty (n = 7), truncal vagotomy and antrectomy (n = 8). Samples of gastric juice were aspirated half hourly or hourly(More)
The effects of pyloroplasty and vagal denervation of the distal stomach on gastric emptying of 10% dextrose have been compared. In a randomized trial, 38 male patients having elective surgery were treated by proximal gastric vagotomy (PGV, N = 10), proximal gastric vagotomy and pyloroplasty (PGV + P, N = 9), total gastric vagotomy (TGV, N = 9), and total(More)
1. The excretion of piperacillin sodium in bile was studied after intravenous injection of 2 g (n = 5) and 4 g (n = 7). All patients had undergone cholecystectomy and exploration of the common bile duct for cholelithiasis. Bile, serum and urine concentrations were measured by a microbiological technique. 2. Peak concentrations of piperacillin were found in(More)
Gastric juice was studied in five patients after Billroth II partial gastrectomy, in six patients after Roux-Y reconstruction, and in eight healthy control subjects. Juice was obtained over a 24 hour period by hourly nasogastric aspiration prior to measurement of pH, total and stable N nitrosocompounds, nitrites, bile acids (total and free), and bacterial(More)
