Utilization of knockout mice to examine the potential role of gastric histamine H2-receptors in Menetrier's disease.
Menetrier's disease is characterized by giant gastric folds with foveolar hyperplasia and cystic dilatation, hypoproteinemia, and enhanced mucus secretion. The etiology remains unresolved and an effective treatment has yet to be established. Here we show that histamine H(2)-receptor deficient mice developed gastric pathophysiological changes resembling Menetrier's disease for up to 17 months of observation. Mutant mice were found to have an increased stomach weight, enlarged gastric folds with cystic dilatation, hypergastrinemia, hypoalbuminemia, increased mucus secretion and overexpression of mucosal transforming growth factor (TGF) alpha. Both a cholecystokinin (CCK)(2)-receptor antagonist and an epidermal growth factor (EGF)-receptor tyrosine kinase inhibitor significantly reduced the increase in stomach weight. It appears that lack or downregulation of histamine H(2)-receptors might be involved in the pathogenesis of Menetrier's disease.

Pseudoachalasia as a late complication of gastric wrap performed for morbid obesity: report of a case.
A 66-year-old woman presented with progressive dysphagia of 10 years' duration. She had undergone a Teflon gastric wrap operation for obesity 20 years earlier. Endoscopic and radiological examinations showed a dilated tortuous esophagus and a contracted stomach. The esophageal manometry findings were consistent with achalasia. She underwent an uneventful total gastrectomy, partial distal esophagectomy, and Roux-en-Y esophagojejunal anastomosis. When last seen, 2 months after her operation, she was not suffering from dysphagia. This case report serves to demonstrate that gastric reservoir wrapping is associated with significant morbidity.

Colonic displacement. Proposed treatment for gastric remnant volvulus due to eventration of the diaphragm.
Displacement of the gastric remnant in patients with left diaphragmatic eventration may lead to gastric remnant volvulus requiring surgical correction. This results from the strong negative intrathoracic pulling force created by the potential subphrenic space an paradoxical movement of th diaphragm. Unless this strong negative force is first eliminated, gastropexy alone is likely to result in recurrence. Obliteration of the subphrenic space by colonic displacement is an effective and simple way of abolishing this negative subdiaphragmatic pulling force. Once this is achieved, any form of gastropexy will suffice to permanently prevent gastric remnant translocation and volvulus.

Do plain films of the chest and abdomen have a role in the diagnosis of acute pancreatitis?
Radiographs taken on the day of admission on 52 patients with acute pancreatitis have been compared with similar radiographs of 30 patients with acute cholecystitis and 22 patients with perforated duodenal ulcer. Two radiologists, who were unaware of the clinical features, looked specifically for the presence of 30 radiological signs. The only abdominal signs seen more frequently in acute pancreatitis were fluid levels in the stomach and duodenum, usually associated with dilatation. Duodenal abnormalities were seen in 42% of patients with acute pancreatitis and 21% of the controls (P less than 0.05) while gastric dilatation with a fluid level was seen in 29% of cases of acute pancreatitis compared with 12% of controls (P less than 0.05). Seventy per cent of the patients with severe acute pancreatitis had an abnormal chest radiograph on admission compared with 18% of those with mild disease. Left pleural effusion was the most common abnormality in severe pancreatitis (43%) and was seen significantly more often than in mild pancreatitis (P less than 0.01) and the control group (P less than 0.05). Therefore, consideration of the admission chest radiograph may help at an early stage to distinguish patients with severe pancreatitis from those with mild disease.

Gastric infarction secondary to small bowel obstruction: a preventable complication after Nissen fundoplication.
Two infants who required a Nissen fundoplication for severe gastroesophageal reflux developed small bowel obstruction 5 and 21 months postoperatively. Their inability to belch or vomit, coupled with inappropriate airway management during resuscitation led to massive gastric dilation, and eventual infarction of their stomach, duodenum, and small intestines. These complications are preventable with appropriate management.

Benefits of prophylactic gastropexy for dogs at risk of gastric dilatation-volvulus.
The lifetime probability of death from gastric dilation-volvulus (GDV) for five dog breeds was estimated based on published breed-specific longevity and GDV incidence. These breeds were Great Dane, Irish Setter, Rottweiler, Standard Poodle and Weimaraner. Lifetime risk (95% CI) of GDV in these breeds ranged from 3.9% (0-11.2%) for Rottweiler to 36.7% (25.2-44.6%) for Great Dane. A decision-tree analysis for prophylactic gastropexy--using lifetime probability of death from GDV and expected cost savings for veterinary services as outcome measures--was undertaken to determine the preferred course of action in several dog breeds. Prophylactic gastropexy was the preferred choice of action for all breeds examined, with the reduction in mortality (versus no gastropexy) ranging from 2.2-fold (Rottweiler) to 29.6-fold (Great Dane). Assuming a prophylactic gastropexy costs US$ 400, the procedure was cost-effective when the lifetime risk of GDV was > or = 34%. The maximum and minimum estimated breakeven costs for the gastopexy procedure ranged from US$ 20 (Rottweiler) to US$ 435 (Great Dane). The cost-effectiveness of prophylactic gastropexy was most sensitive to the cost of treating GDV (US$ 1500). Prophylactic gastropexy raises ethical issues that need to be considered by veterinarians and dog breeders.

Gastric disease in the dog and cat.
The physiology of the normal gastric defence mechanisms in the dog and cat is reviewed to emphasize the routes by which drugs can be used to protect the gastric mucosa. The action of the main anti-ulcer and pro-kinetic drugs are discussed in relation to the diseases that they may be used to treat. Gastric disease in the form of gastric dilatation/volvulus, chronic vomiting without obstruction and gastric outflow disease are described from the point of view of diagnosis and treatment.

Prenatal diagnosis of gastroesophageal reflux by color and pulsed Doppler ultrasonography in a case of congenital pyloric atresia.
A case of pyloric atresia diagnosed in the third trimester is described. Real-time ultrasonographic examination revealed polyhydramnios, enlarged stomach, evident gastric peristalsis and esophageal dilatation. Color and pulsed Doppler studies of the gastroesophageal junction revealed the presence of a biphasic flow pattern that was consistent with gastroesophageal reflux.

Hepaticogastrostomy by echo-endoscopy as a palliative treatment in a patient with metastatic biliary obstruction.
A palliative hepaticogastrostomy was performed under endoscopic ultrasound guidance in a patient with inoperable hepatic hilar obstruction, creating an anastomosis between the dilated left hepatic duct and the stomach, to relieve symptoms of cholangitis and to allow biliary drainage. This therapeutic procedure was used as an alternative method of drainage of the biliary tree because endoscopic retrograde cholangiopancreatography was not possible and because the percutaneous metallic stent which had been inserted earlier had become occluded (probably by tumor overgrowth). It was a two-step procedure. In the first step a hepatic duct was punctured through the gastric wall with placement of a plastic stent, which created a fistula between them. In a second step a covered, metallic, self-expandable stent was substituted for the plastic stent to maintain the anastomosis and to improve patency over the medium term. The patient's fever was relieved and the bilirubin level fell; the patient remained asymptomatic at the five-months-follow-up.

Role of melatonin in reducing water avoidance stress-induced degeneration of the gastrointestinal mucosa.
We investigated the role of melatonin on water avoidance stress (WAS)-induced degeneration of the gastric, ileal and colonic mucosa. Wistar albino rats were exposed to acute WAS (aWAS group) or chronic WAS (cWAS group). Before exposing animals to acute (aWAS + mel group) or chronic WAS (cWAS + mel group), 10 mg/kg melatonin was injected i.p. The stomach, ileum and colon samples were investigated under light and scanning electron microscope. Malondialdehyde (MDA) and glutathione (GSH) levels were also determined. In both aWAS and cWAS groups, the epithelium of stomach showed ulceration in some areas, dilatations of the gastric glands and degeneration of gastric glandular cells; prominent congestion of the capillaries after WAS was apparent. In the cWAS group, severe vascular congestion was observed along with degeneration of ileal and colonic epithelium. MDA levels were increased and GSH levels were decreased in all tissues in both the aWAS and cWAS groups. The morphology of gastric, ileal and colonic mucosa in both aWAS + mel and cWAS + mel groups showed that the indole significantly reduced degeneration of the gastrointestinal mucosa. Decreased MDA and increased GSH levels were observed in the WAS + mel groups. Based on the results, melatonin treatment significantly prevented WAS induced degenerative morphological and biochemical changes of gastrointestinal mucosa.

Chronic cryptosporidiosis in Australian elapid snakes: control of an outbreak in a captive colony.
An outbreak of chronic cryptosporidiosis resulting in hypertrophic gastritis occurred in a captive colony of Australian elapid snakes. Two species of the genus Notechis were involved: Notechis ater (Black Tiger Snake) and Notechis scutatus (Eastern or Mainland Tiger Snake). The infection was eventually fatal in all 9 affected snakes. Typical histopathological findings of the stomach included mucosal thickening with cystic dilatation of gastric glands, moderate oedema and fibrosis of the lamina propria, and a mild to moderate patchy infiltration of inflammatory cells. Procedures implemented to contain the outbreak included the use of a formaldehyde-based disinfectant, prompt removal of faecal matter, uneaten and regurgitated food from enclosures, and examination of faecal specimens for Cryptosporidium oocytes and other pathogens.

Acute gastric dilatation with infarction and perforation. Report of fatal outcome in patient with anorexia nervosa.
This is a report of a 22-year-old woman with treated anorexia nervosa who died of complications of acute gastric dilatation-that is, infarction and perforation with severe and irreversible shock. Binge eating and drinking, precipitated by emotional crises, contributed to her acute gastric dilatation. This complication of anorexia nervosa has been previously reported, but, unlike the others, this case ended fatally. The literature is reviewed.

Neoplastic autovagotomy causing gastric stasis.
Neoplastic autovagotomy causing atonic gastric stasis is extremely rare. Two cases are reported in which marked gastric stasis was complicated by a bezoar and a gastric volvulus respectively. Both cases were associated with a left hilar bronchial carcinoma, and malignant invasion of the vagus nerve may have been the underlying cause.

Retrospective analysis of laparoscopic gastric banding technique: short-term and mid-term follow-up.
BACKGROUND: Although adjustable gastric banding shows good results concerning weight loss, several complications such as excessive vomiting, total dysphagia, and slipping of the stomach through the band with pouch dilatation may occur rather frequently. Different types of adjustable bands are available to prevent these short- and mid-term complications. METHODS: In this retrospective study, 120 consecutive laparoscopic adjustable gastric bandings were performed. In group I, 50 patients were treated with adjustable silicone gastric banding (ASGB) by an intragastric balloon calibration technique. Group II (n = 29) received the same band by a surgical technique with tunneling behind the esophagus toward the angle of His. Group III (n = 41) received Swedish adjustable gastric banding (SAGB) by the same technique as in Group II. RESULTS: Weight loss was approximately 15% of the excess weight after 3 months, 30% after 6 months, and 45% after 12 months in all groups. Total dysphagia was significantly more frequent in Groups I and II. The incidence of slipping of the band and pouch dilatation was more frequent in Group II. CONCLUSION: The diameter of the ASGB band is rather small and can cause total dysphagia independently of surgical technique. The SAGB is easy to perform and seems less vulnerable to complications like dysphagia and slipping of the band, probably because of the individual adjustment of the stoma diameter during surgery and good fixation of both band and ventral pouch with separate posterolateral sutures.

[Effect of a couple of stimulants on the gastric motility (author's transl)].
The effects of the stimulants such as antral distention, administration of gastrin and insulin on the gastric motility were investigated in the dogs with innervated antral pouches. The results were as follows: 1. The gastric motility was markedly increased by these stimulants and characteristic motility patterns were recognized in each stimulants. 2. Antral distention stimulated strongly the contraction pressure but not in the frequency of the gastric contractions. 3. Gastrin produced regular and higher frequency contractions and the decrease in contraction pressure of the stomach. 4. Insulin stimulated both of the contraction pressure and the frequency of the gastric contractions. 5. The tests of compound stimulation by each two of these stimuli demonstrated that gastrin constantly produced an increase in frequency and a decrease in contraction pressure and that antral distention always increased the contraction pressure of the stomach.
