The authors studied gastric secretion in 117 persons with alimentary obesity of degree II and III along with the morphological picture of the gastric mucosa. The secretion was investigated by the fractional method, pH-metry and without tubage. In the majority of patients with alimentary obesity gastric secretion proved to be normal. In these patients a greater appetite was not associated with an intensified secretion. In all of the cases under examination the morphological picture revealed the presence of chronic gastritis.

The authors examined 131 patients with degree III-IV alimentary-constitutional obesity before and after operation for formation of a "small stomach". The average body weight of the patients before surgery was 145 +/- 2.28 kg. In the first 12 postoperative months it reduced by 41.9 +/- 1.76 kg as compared to the initial weight. Diminution of body weight in the second year was statistically insignificant. All patients underwent endoscopy of the esophagus and stomach before and after the operation with appraisal of the degree of macroscopic changes of the mucous membrane. The incidence of chronic gastritis and esophagitis reduced in the postoperative late-term periods more than 1.5 times, that of erosive lesions more than 10 times. Targent measurement of the transmural potential difference (TPD) of the esophagus and stomach was conducted in 36 patients. The TPD value is much less in patients with obesity than in the control group of healthy individuals. After operation the TPD value grows significantly which is due to changes of the diet regimen, reduced amount of the ingested food, reduction of body weight, and improved processes of microcirculation in the mucous membrane of the gastrointestinal tract.

In order to estimate the incidence and significance of aspiration during anaesthesia, a study of cases in which this complication had occurred was made at the Karolinska Hospital. With the aid of the anaesthetic recordkeeping system of the Department of Anaesthesia and the computer-based register of diagnoses of in-patients at the hospital, all cases in which aspiration was recorded were retrieved. Eighty-three cases of aspiration were retrieved from the file of anaesthetic records and four from the in-patient register. This constitutes an incidence of 4.7 aspirations in 10 000 anaesthetics, or 1 in 2131. The patients most often affected were children and the elderly. In 83% of the cases there were one or more preoperative factors indicating an increased risk for aspiration, such as emergency operation (38 cases, 43%), upper abdominal or emergency abdominal surgery (14 cases, 16%), a history indicating delayed gastric emptying (e.g. peptic ulcer/gastritis, pregnancy, obesity, unusual stress or pain, elevated intracranial pressure, 54 cases, 61%). In 29 cases (33%) there was a history indicating an increased risk of regurgitation, e.g. nasogastric tube, oesophageal disease or pregnancy. In 15 cases of elective surgery, no history of increased risk for aspiration could be found. In 67% of those cases the aspiration was preceded by difficulties involving the airways or intubation. The incidence of aspiration was more than sixfold higher during the night than during regular daytime working hours. In 41 cases (47%) the aspiration led to aspiration pneumonitis confirmed by x-ray. Fifteen patients (17%) needed mechanical ventilation, and four died.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this work was to ascertain if diabetes and obesity can affect gastric colonization by Helicobacter pylori. 59 hospitalized subjects with dyspepsia and endoscopic antral gastritis were selected. They were divided into three groups: I) 13 patients with normal body weight and without disease other than gastritis (control group); II) 15 patients with essential obesity of whom 10 had impaired glucose tolerance (IGT); III) 31 patients with type II diabetes mellitus, of whom 14 were obese. Three gastric biopsies were obtained from each patient for histologic examination and H. pylori detection by means of rapid urea test, culture and histological evidence of Helicobacter-Like Organisms (HLO). Age, sex, blood glucose, cholesterol, triglycerides, HDL-cholesterol, basal gastrine, duration of illness, body weight were statistically analysed. Differences between the three groups were not statistically significant. There was a higher prevalence of H. pylori infection both in obese and in diabetic patients with respect to control subjects. Prevalence became still higher in obese patients with impaired glucose tolerance. Among the three tests used for the detection of H. pylori, culture and rapid urea were reliable and specific, while the histologic test was highly sensitive but barely specific. Our data suggest that both obesity and type II diabetes may be associated with an increased incidence of H. pylori-colonization. This could be related to the reduced gastric motility observed in both pathologies and chemical changes in gastric mucosa following non-enzymatic glycosylation processes.

To explore the potential contributions of gastroesophageal reflux disease, as opposed to Helicobacter pylori infection, to the development of gastric carditis, we evaluated gastric carditis (using the criteria of the updated Sydney system for the classification of gastritis), clinical and morphologic features of esophagitis, and H. pylori infection (evaluation of Steiner stains) in biopsy specimens from the gastroesophageal squamocolumnar junction. We correlated clinical, endoscopic, and histologic features in an unselected group of 116 patients. Some degree of carditis was found in 107 (92%) of the patients. The mean age of the patients increased with increasing severity of carditis (P < .05). The various groups of patients with different degrees of carditis did not differ significantly in sex ratio, ethnic background, presence of obesity, percentage having symptoms of gastroesophageal reflux disease (such as heartburn, regurgitation, dysphagia, or odynophagia), endoscopic evidence of esophagitis and columnar epithelium in the distal esophagus, or histologic evidence of active esophagitis. The presence, however, of active gastritis and H. pylori infection in the distal stomach and/or in the cardia was significantly associated with carditis. In patients without carditis, H. pylori was not detected in any cardiac or distal gastric biopsy specimen. In contrast, H. pylori was demonstrated in gastric tissue samples (either from the cardia or distally) of patients with carditis, with the prevalence rate increasing with greater degrees of cardiac inflammation. The H. pylori prevalence rate was 12% in the group with mild carditis, 40% in those with moderate carditis, and 57% in patients with marked carditis (P = .0001). In summary, carditis is commonly found in patients with symptoms related to upper gastrointestinal diseases. From analysis of our study cohort, we concluded that carditis was significantly associated with H. pylori infection and active gastritis but not with symptoms or signs of gastroesophageal reflux disease. These findings suggest that carditis with histologic features similar to those of gastritis in the distal stomach was a sequel of H. pylori infection and represented a part of an H. pylori--associated gastric inflammation.

BACKGROUND: Few papers assess quality of life after vertical banded gastroplasty (VBG). METHODS: 100 patients with severe obesity (preoperatively mean BMI 41.7 kg m(2)) answered an interview 60 (+/- 2.5) months after VBG. RESULTS: There was no fatal outcome. Nine patients had pulmonary embolus; ten patients required reoperation because of stomal stenosis. Of the 89 patients that still bore a gastroplasty at the moment of the interview, 65 had lost more than 40% of their excess weight (= "success'). Improvement in quality of life of these 89 patients was reflected by significant diminution of depression and back pains. Significant diminution of arterial hypertension and improvement of professional satisfaction, and of social, physical, and sexual activity was significantly related to weight loss. CONCLUSION: VBG resulted generally in a favorable long-term effect on quality of life. However, patients should be informed preoperatively about potential side-effects such as possible persistent vomiting after several years, esophagitis and gastritis, restriction in the choice of foods and prolongation of meals.

Vertical banded gastroplasty, reported by Mason in 1982, is an effective method to control pathologic obesity (BMI>40 kg/m2). With the widespread of this procedure and the introduction of laparoscopic approach several complications are described in literature: gastroesophageal reflux, esophagitis, gastritis, gastric bleeding and perforations, prolonged vomit, dislocation of gastric ring, cholelithiasis, gastric fistulas, gastric stomal stenosis, dehiscence of vertical stomach staple line. From 2 to 10% of patients are reoperated because of inefficacy of treatment or short and long-term complications. Morbidity and mortality associated to reoperations are still high and it is difficult to identify criteria for an appropriate revision procedure. This can occur through endoscopy, laparotomy or laparoscopy, depending on clinical and radiologic feature. Dehiscence of vertical stomach staple line, observed in 10-20% of cases, even if asymptomatic, can lead to bad complications such as fistulas, peritonitis and sepsis. The case of a young woman, who underwent a vertical banded gastroplasty for pathologic obesity (117 kg, h 167 cm, BMI 42/m2) and subsequent laparotomies in the attempt to correct vertical staple line dehiscence, is reported. The patient came to our observation in a septic shock caused by peritonitis and ARDS and a total gastrectomy with Roux-en-Y esophago-jejunostomy was performed.

This study presents the result of the studies explaining the effects of acupuncture on various systems and symptoms. It has been determined that endomorphin-1, beta endorphin, encephalin, and serotonin levels increase in plasma and brain tissue through acupuncture application. It has been observed that the increases of endomorphin-1, beta endorphin, encephalin, serotonin, and dopamine cause analgesia, sedation, and recovery in motor functions. They also have immunomodulator effects on the immune system and lipolithic effects on metabolism. Because of these effects, acupuncture is used in the treatment of pain syndrome illnesses such as migraine, fibromyalgia, osteoarthritis, and trigeminal neuralgia; of gastrointestinal disorders such as disturbance at gastrointestinal motility and gastritis; of psychological illnesses such as depression, anxiety, and panic attack; and in rehabilitation from hemiplegia and obesity.

Urocortins, three paralogs of the stress-related peptide corticotropin-releasing factor (CRF) found in bony fish, amphibians, birds, and mammals, have unique phylogenies, pharmacologies, and tissue distributions. As a result and despite a structural family resemblance, the natural functions of urocortins and CRF in mammalian homeostatic responses differ substantially. Endogenous urocortins are neither simply counterpoints nor mimics of endogenous CRF action. In their own right, urocortins may be clinically relevant molecules in the pathogenesis or management of many conditions, including congestive heart failure, hypertension, gastrointestinal and inflammatory disorders (irritable bowel syndrome, active gastritis, gastroparesis, and rheumatoid arthritis), atopic/allergic disorders (dermatitis, urticaria, and asthma), pregnancy and parturition (preeclampsia, spontaneous abortion, onset, and maintenance of effective labor), major depression and obesity. Safety trials for intravenous urocortin treatment have already begun for the treatment of congestive heart failure. Further understanding the unique functions of urocortin 1, urocortin 2, and urocortin 3 action may uncover other therapeutic opportunities.

Submucosal cysts (SMCs) might result from severe gastritis and be related to gastric carcinogenesis, although direct evidence is limited. We studied clinicopathologic findings for gastric cancers arising in mucosa with SMC and the relation to gastritis. In 504 submucosal invasive cancer cases, SMC was found in 100. Comparison of degrees of gastritis using the Updated Sydney system, thickness of muscularis mucosae, and the patients' smoking and drinking habits and obesity showed significant variation between cases of cancer with and without SMC. In the stomach with SMCs, cancers were predominantly differentiated-type adenocarcinomas in men and showed a significant tendency for location in the upper gastric region. Intestinal metaplasia was significantly more severe and the muscularis mucosae were thicker in cancer cases with SMC in comparison with cases without SMC and control cases of gastrointestinal stromal tumor (GIST). Atrophy was also significantly more severe in cancer cases with and without SMC than in cases of GIST. The Brinkman index was also significantly higher. Cases of gastric cancer with SMC show characteristic clinicopathologic features, and SMC formation may be caused by gastritis and influenced by smoking.
