    Full Text Available A case of acute intestinal anisakiasis has been reported; a nematode larva being found in the submucosa of the ileum of a woman in Jaén (Spain. The source of infection was the ingestion of raw Engraulis encrasicholus. On the basis of its morphology, the worm has been identified as a fourth-stage larva of Anisakis simplex. In Spain, this is the ninth report of human anisakiasis and also probably the first case of anisakiasis caused by a fourth-stage larva of A. simplex.

    Anisakiasis is a parasitic disease acquired by eating raw or poorly cooked fish infested with nematode larvae of the Anisakiadae family. The diagnosis of this parasitic disease is difficult if the epidemiological background is overlooked because the symptoms of presentation are non-specific. Therefore, in patients with a picture of acute abdomen and a recent history of eating raw fish, echography and/or abdominal CT may yield a diagnosis. (Author) 6 refs

  3. Should the host reaction to anisakiasis influence the treatment?: Different clinical presentations in two cases

    Directory of Open Access Journals (Sweden)

    Stefano Pontone

    Full Text Available Gastrointestinal anisakiasis is a parasitic infection occurring in people that consume raw or inadequately cooked fish or squid. It is frequently characterized by severe epigastric pain, nausea and vomiting caused by the penetration of the larvae into the gastric wall. Acute gastric anisakiasis with severe chest discomfort is rarely reported in Italy. On the other hand, gastro-allergic anisakiasis with rash, urticaria and isolated angioedema or anaphylaxis is a clinical entity that has been described only recently. Also, if patients usually develop symptoms within 12 hours after raw seafood ingestion, not always endoscopic exploration can promptly identify the Anisakis larvae. Moreover, some authors consider the prevailing allergic reaction as a natural and effective defense against the parasitic attack. We report two cases of peculiar manifestations of anisakiasis in both acute and chronic forms (severe chest discomfort and anaphylactoid reaction.

    Full Text Available The clinical characteristic of gastrointestinal anisakiasis is severe abdominal pain after eating raw fish. Intestinal anisakiasis is more uncommon than gastric anisakiasis. Most patients with intestinal anisakiasis need hospitalization because anisakiasis can cause intestinal obstruction, ileus, peritonitis or intestinal perforation. We report a case of intestinal anisakiasis. A 43-year-old woman presented with symptoms of intermittent abdominal pain 2 days after eating raw fish. Her brother had eaten the same food and had been suffering from gastric anisakiasis. Abdominal ultrasonography in this patient showed localized jejunal wall thickening with dilated lumen of proximal jejunum and ascites. According to the clinical course and examinations, she was diagnosed with intestinal anisakiasis. Administration of prednisolone 5 mg/day and olopatadine hydrochloride 10 mg/day improved her symptoms quickly without hospitalization. Prednisolone was administered for 10 days, and olopatadine hydrochloride was administered for a total of 6 weeks according to ultrasonographic findings. Six months after the treatment, the abdominal ultrasonography demonstrated normal findings. This case demonstrates that ultrasonography was quite useful for the diagnosis and surveillance of intestinal anisakiasis. Furthermore, treatment with corticosteroid and an antiallergic agent could be an option for patients with intestinal anisakiasis.

    The prevalence of anisakiasis is rare in the United States and Europe compared with that in Japan, with few reports of its presentation in the emergency department (ED). This study describes the clinical, hematologic, computed tomographic (CT) characteristics, and treatment in gastric and small intestinal anisakiasis patients in the ED. We retrospectively reviewed the data of 83 consecutive anisakiasis presentations in our ED between 2003 and 2012. Gastric anisakiasis was endoscopically diagnosed with the Anisakis polypide. Small intestinal anisakiasis was diagnosed based on both hematologic (Anisakis antibody) and CT findings. Of the 83 cases, 39 had gastric anisakiasis and 44 had small intestinal anisakiasis based on our diagnostic criteria. Although all patients had abdominal pain, the gastric anisakiasis group developed symptoms significantly earlier (peaking within 6 hours) than the small intestinal anisakiasis group (peaking within 48 hours), and fewer patients with gastric anisakiasis needed admission therapy (5% vs 57%, Pfindings revealed edematous wall thickening in all patients, and ascites and phlegmon of the mesenteric fat were more frequently observed in the small intestinal anisakiasis group. In the ED, early and accurate diagnosis of anisakiasis is important to treat and explain to the patient, and diagnosis can be facilitated by a history of raw seafood ingestion, evaluation of the time-to-symptom development, and classic CT findings.

    Full Text Available Small intestinal anisakiasis is a rare disease that is very difficult to diagnose, and its initial diagnosis is often surgical. However, it is typically a benign disease that resolves with conservative treatment, and unnecessary surgery can be avoided if it is appropriately diagnosed. This case report is an example of small intestinal obstruction caused by anisakiasis that resolved with conservative treatment. A 63-year-old man admitted to our department with acute abdominal pain. A history of raw fish (sushi ingestion was recorded. Abdominal CT demonstrated small intestinal dilatation with wall thickening and contrast enhancement. Ascitic fluid was found on the liver surface and in the Douglas pouch. His IgE (RIST was elevated, and he tested positive for the anti-Anisakis antibodies IgG and IgA. Small intestinal obstruction by anisakiasis was highly suspected and conservative treatment was performed, ileus tube, fasting, and fluid replacement. Symptoms quickly resolved, and he was discharged on the seventh day of admission. Small intestinal anisakiasis is a relatively uncommon disease, the diagnosis of which may be difficult. Because it is a self-limiting disease that usually resolves in 1-2 weeks, a conservative approach is advisable to avoid unnecessary surgery.

    Full Text Available Gastric necrosis due to acute massive gastric dilatation is relatively rare. Vascular reasons, herniation, volvulus, acute gastric dilatation, anorexia, and bulimia nervosa play a role in the etiology of the disease. Early diagnosis and treatment are highly important as the associated morbidity and mortality rates are high. In this case report, we present a case of gastric necrosis due to acute gastric dilatation accompanied with the relevant literature.

  10. ACUTE GASTRIC DILATATION IN CHILDREN

    Directory of Open Access Journals (Sweden)

    Full Text Available Acute gastric dilatation is a rare surgical condition in children, which often results from blunt abdominal trauma. This condition is characterized by the gut-brain connection disorder or gastric muscular layer damage, which results in atony. Gradual gastric stretching with fluid contents and gases in the end leads to the development of various types of intestinal obstruction. When conservative measures are not sufficient (in rare cases, it is reasonable to resort to operative intervention. Several cases of such a pathology have been published around the world. This condition has been observed not only at the blunt abdominal trauma, but also at lesions of central and peripheral nervous systems and in patients with anorexia nervosa and bulimia in the event of excessive food consumption. The article presents a clinical case study and a follow-up analysis of a child with posttraumatic acute gastric dilatation. The authors describe clinical manifestations, pathogenesis and diagnostic algorithm, which allowed establishing this rare diagnosis. Along with the conventional drugs and intensive care measures, the treatment involved a complex of mini-invasive endosurgical and endoscopic manipulations, including laparoscopic jejunostomy, which was performed in order to provide long-term enteral feeding. The clinical case study demonstrated that the use of diagnostic laparoscopy helps to establish nature of the gastric damage correctly and formulate the following optimal treatment tactics on the basis of the obtained data.

    To assess the diagnostic performance of CT signs of gastric volvulus in both confirmed cases and control subjects. We retrospectively reviewed CT findings in 10 patients with surgically confirmed acute gastric volvulus and 20 control subjects with gastric distension. Two radiologists independently evaluated CT images for risk factors of gastric volvulus, direct findings of gastric volvulus by assessing gastric dilatation, the presence of an antropyloric transition point, the respective position of the different stomach segments and of the greater and lesser curvatures, stenosis of the gastric segments through the oesophageal hiatus and for findings of gastric ischemia. The sensitivity and specificity of each finding were calculated. The most sensitive direct signs of gastric volvulus were an antropyloric transition point without any abnormality at the transition zone and the antrum at the same level or higher than the fundus. The presence of both these two findings as diagnostic criteria of gastric volvulus had 100% sensitivity and specificity for the diagnosis of gastric volvulus. There was no association between CT signs of ischemia and final bowel ischemia at pathology. CT is both highly sensitive and specific for diagnosing acute gastric volvulus. CT is highly reliable for diagnosing acute gastric volvulus with two findings. The two signs are gastropyloric transition zone and abnormal location of the antrum. This allows fast surgical management of this emergency.

    Full Text Available Acute gastric volvulus is a rare, but potentially life-threatening, cause of upper gastro-intestinal obstruction. The diagnosis can prove clinically challenging, and hence there is increased reliance on imaging. There are different types of gastric volvulus, with the variant presented in our case being the less commonly encountered mesenteroaxial gastric volvulus. Some of the CT features of gastric volvulus are described, and the usefulness of CT in assisting with the diagnosis is highlighted.

    To evaluate the radiographic findings of gastrointestinal anisakiasis with clinical and pathologic correlation. In ten patients, findings were retrospectively analysed. There were two cases of the gastric variety of gastrointestinal anisakiasis and eight of the intestinal, and they were diagnosed during gastroscopy, by resection during surgery, and on the basis of typical clinical findings. All ten patients underwent both plain radiography and CT scanning of the abdomen. US was performed in five patients and an upper gastrointestinal series in one. Clinical data were evaluated with regard to a history of raw fish ingestion, time from ingestion of raw fish to onset of symptoms, location of abdominal pain, and laboratory data. Radiologic findings were analysed in terms of wall thickening and appearance, mesenteric infiltration, bowel dilatation proximal to lesion, and ascites. All patients had a history of recent ingestion of raw fish and complained of severe abdominal pain that occurred approximately 7-48 hours later. Pain occurred in the lower abdomen in five patients, the epigastrium in four, and the right lower abdomen in two. Laboratory test disclosed the leukocytosis in eight patients and eosinophilia in three. In all cases of intestinal anisakiasis, ileus was demonstrated on plain radiographs of the abdomen, while the upper gastrointestinal series showed mucosal thickening and multiple filling defects. US findings were bowel thickening and dilation, and on CT images, wall thickening revealed a target sign. Mesenteric infiltration and ascites were seen in seven patients. In four who underwent surgery, a cross-section through the lesion revealed submucosal eosinophilic granuloma with anisakis larva. Although the CT findings are non-specific, taken in conjunction with characteristic clinical findings, they may be helpful in the diagnosis of gastrointestinal anisakiasis. (author)

    We wanted to describe the CT findings of small bowel anisakiasis with the pathologic correlation. Four patients with surgically and pathologically proven small bowel anisakiasis were included in this retrospective study. They were three men and one woman and their ages ranged from 28 to 43 years (mean age: 38 years). We evaluated their clinical, CT and histological findings. All the patients had a history of ingesting raw fish within 24 hours from the time of symptom onset. They complained of abdominal pain (n=4), nausea (n=4), vomiting (n=2) and diarrhea (n=1). Physical examination revealed tenderness (n=4), rebound tenderness (n=4) and increased bowel sounds (n=3). Leukocytosis was noted in all the patients on the laboratory examination. None of the patients showed eosinophilia. The CT findings were segmental small bowel wall thickening with preserved layering (n=4), focal segmental luminal narrowing with proximal dilatation (n=4), peritoneal thickening (n=3), mesenteric or omental infiltration (n=4) and varying degrees of ascites (n=4). On the histopathologic examination, they revealed an infiltration of eosinophils (n=4) in all layers of the bowel wall with severe edema. The larvae were found on surgico-pathologic examination in all the cases. The CT findings may be helpful to make the specific diagnosis of small bowel anisakiasis in a patient with the clinical findings of an acute abdomen and a history of eating raw fish

    Full Text Available Acute poisonings are a frequent complaint in emergency departments and therapy which prevents the absorption of toxic products taken orally is often indicated: one such option is gastric lavage. Gastric lavage is a digestive decontamination technique whose goal is to remove the maximum amount of poison from the stomach and prevent its absorption. The procedure involves inserting a gastric tube into the stomach through the mouth or nose; firstly to aspirate all the stomach contents and then to perform gastric washing manoeuvres. The effectiveness of gastric lavage is limited and involves a risk of iatrogenesis, and therefore the indications and contraindications should be carefully considered and the technique carried out meticulously to increase its effectiveness and reduce complications, primarily bronchoaspiration. Gastric lavage may be used in conjunction with other digestive decontamination techniques such as administration of activated charcoal. This gastric lavage protocol is based on a review of the literature on this procedure and is supported by the expertise of our research group in gastrointestinal decontamination techniques in patients with acute poisoning.

    We describe the case of a 68-year-old otherwise healthy male who presented to our emergency room with signs and symptoms of acute appendicitis. Exploratory surgery revealed a normal appendix. Further examination revealed an enlarged lymph node-like mass of tissue near the appendix, in the ileocecal mesentery. This mass was removed and was found to be inflamed heterotopic gastric tissue. Although reports of heterotopic gastric tissue in the literature are common, we believe that this case represents the first report of inflamed heterotopic gastric tissue simulating appendicitis.

  3. Management of acute gastric varices bleeding

    Directory of Open Access Journals (Sweden)

    Chen-Jung Chang

    2013-10-01

    Full Text Available Gastroesophageal varices bleeding is a major complication in patients with cirrhosis. Gastric varices (GVs occur in approximately 20% of patients with portal hypertension. However, GV bleeding develops in only 25% of patients with GV and requires more transfusion and has higher mortality than esophageal variceal (EV bleeding. The best strategy for managing acute GV bleeding is similar to that of acute EV bleeding, which involves airway protection, hemodynamic stabilization, and intensive care. Blood transfusion should be cautiously administered in order to avoid rebleeding. Vasoactive agents such as terlipressin or somatostatin should be used when GV bleeding is suspected. Routine use of prophylactic antibiotics reduces bacterial infection and lowers rebleeding rates. By administering endoscopic cyanoacrylate injection, the initial hemostasis rate achieved is at least 90% in most cases; the average mortality rate of GV bleeding is approximately 10–30% and the rebleeding rate is between 22% and 37%. Although endoscopic injection of cyanoacrylate is superior to sclerotherapy and band ligation, and has remained the treatment of choice for treating acute GV bleeding, the outcome of this treatment is still unsatisfactory. New treatment options, such as thrombin injection, transjugular intrahepatic portosystemic shunts, or balloon-occluded retrograde transvenous obliteration, have shown promising results for acute GV bleeding. However, randomized controlled trials are needed to compare the efficacy of these therapies with cyanoacrylate.

    Acute gastric volvulus in children is uncommon. This paper reports a case presented in a 14-year-old female whose diagnosis was suspected preoperatively taking into account the Brouchardt triad (vomiting, epigastric pain and inability to pass the nasogastric tube into the stomach). The child underwent laparatomy and the final diagnosis was mesenteroaxial gastric volvulus complicated with gastric perforation. Closure of the perforation and gastropexy were performed and the operative results were satisfactory.

    Acute gastric volvulus requires emergency surgery, and a laparoscopic approach for both acute and chronic gastric volvulus was reported recently to give good results. The case of a 50-year-old patient with acute primary gastric volvulus who was treated by laparoscopic reduction and percutaneous endoscopic gastrostomy is described here. This approach seems to be feasible and safe for not only chronic gastric volvulus, but also acute gastric volvulus.

  8. Borchardt Triade: A Symptom of Acute Gastric Volvulus

    Full Text Available Gastric volvulus, especially cases with an acute onset, may result in strangulation, perforation, peritonitis, shock and death. The disease is rarely seen in children, but early diagnosis and treatment is essential due to its life-threatening potential. In patients with acute gastric volvulus, the clinical Borchardt triade may be observed, which is characterized by acute severe pain and distension in the upper abdomen or lower thoracic region, retching and the inability to pass a nasogastric tube. In this article, We  aimed to emphasize the Borchardt’s triad by presenting a pediatric case who was diagnosed with Borchardt’s triad and who had acute mesenteric axial gastric volvulus which diaphragmatic hernia and mobile (wandering spleen were accompanied.

    Acute presentation of gastric volvulus is a rare condition with a high mortality for acute ischaemia. This study was undertaken to investigate the acute management, diagnosis, and long-term outcomes of patients presenting with acute gastric volvulus. Cases were reviewed retrospectively from 2004 to 2014. Patients presenting as an emergency admission with acute gastric volvulus were included. Thirty-six patients were included, five of whom had previous surgery. The mean age was 71 years old. All patients presented with vomiting and chest/epigastric pain. CT was diagnostic in all 26 patients. Barium swallow was diagnostic in two/four patients. OGD was diagnostic in 9 of 20 patients. All patients had an NG tube placed, and eight patients were treated conservatively and made a full recovery. Twenty-nine patients proceeded to surgery. Nine had a laparoscopic repair with two open conversions. Four patients had gastric necrosis, and all had open surgery with resection. Three patients had a mediastinal perforation, and one patient required an additional thoracotomy. All patients with viable stomach had a hiatal repair (where appropriate), 11 had a gastropexy, and 11 had a fundoplication. Mortality for gastric necrosis/perforation was 30 %. Mean postoperative stay was 4 days for laparoscopic repair and 8 days for uncomplicated open surgery. Nine of twenty-nine had transient dysphagia postoperatively. Three of eight patients treated conservatively had an elective procedure subsequently. Acute paraoesophageal hiatus hernia requires early resuscitation and diagnosis. CT should be favoured in assessment, and an NG tube placed promptly. A conservative management may be considered safely in stable patients. Surgical management should be prompt for unstable patients. Gastric ischaemia or perforation has a mortality of 30 %. Laparoscopic repair has a shorter postoperative stay, but has a higher recurrence rate. Surgery for patients without gastric ischaemia has good long

    Full Text Available BACKGROUND: Postoperative acute kidney injury (AKI, a serious surgical complication, is common after cardiac surgery; however, reports on AKI after noncardiac surgery are limited. We sought to determine the incidence and predictive factors of AKI after gastric surgery for gastric cancer and its effects on the clinical outcomes. METHODS: We conducted a retrospective study of 4718 patients with normal renal function who underwent partial or total gastrectomy for gastric cancer between June 2002 and December 2011. Postoperative AKI was defined by serum creatinine change, as per the Kidney Disease Improving Global Outcomes guideline. RESULTS: Of the 4718 patients, 679 (14.4% developed AKI. Length of hospital stay, intensive care unit admission rates, and in-hospital mortality rate (3.5% versus 0.2% were significantly higher in patients with AKI than in those without. AKI was also associated with requirement of renal replacement therapy. Multivariate analysis revealed that male gender; hypertension; chronic obstructive pulmonary disease; hypoalbuminemia (<4 g/dl; use of diuretics, vasopressors, and contrast agents; and packed red blood cell transfusion were independent predictors for AKI after gastric surgery. Postoperative AKI and vasopressor use entailed a high risk of 3-month mortality after multiple adjustments. CONCLUSIONS: AKI was common after gastric surgery for gastric cancer and associated with adverse outcomes. We identified several factors associated with postoperative AKI; recognition of these predictive factors may help reduce the incidence of AKI after gastric surgery. Furthermore, postoperative AKI in patients with gastric cancer is an important risk factor for short-term mortality.

    The origin of the gas in the stomachs of dogs with acute gastric dilatation or gastric dilatation with volvulus (GDV) often is disputed. We tested the hypothesis that gaseous distention resulted from aerophagia. Ten cases of GDV that were submitted to an emergency clinic were sampled intraoperatively. With the abdomen open, the needle of a vacutainer blood collection set was inserted into the distended stomach, and gas was collected into 10 mL glass vacutainer vials with rubber stoppers. These were stored at room temperature for 1-7 days and then analyzed by gas chromatography and mass spectroscopy. CO2 composition ranged from 13 to 20%. One dog had an H2 concentration of 29%. Because the CO2 content of atmospheric air is less than 1%, these findings suggest that the gaseous gastric distention in GDV is not the result of aerophagia.

    Acute colonic volvulus accounts for 10% of all intestinal obstructions being the transverse colon volvulus an exceptional localization (2-4%). Late diagnosis is made as there are no pathognomonic clinical or radiological findings for this pathology. We present the case of an 81 year-old male with acute transverse colon volvulus that involved the gastric antrum causing irreversible ischemia. Subtotal gastrectomy, subtotal colectomy and reconstruction with Y en Roux gastrojejunostomy and ileosigmoid anastomosis was performed given the good overall status of the patient. Decompressive colonoscopy is not advised given the high probability of ischemic lesions in these cases; surgical exploration is mandatory in these circumstances. Surgical detortion with or without colopexia carries important recurrence rates. Treatment of choice includes colectomy with or without primary anastomosis. There are no reports on gastric ischemic necrosis in the setting of a transverse colon volvulus making this case unusual and unique.

    Full Text Available Acute myocardial infarction and perforated peptic ulcer disease with associated peritonitis are both medical emergencies requiring urgent intervention. This patient presented with both emergencies simultaneously. Current literature is devoid of guidance as to which should be addressed initially. A multidisciplinary discussion was conducted leading to a unanimous decision for initiating percutaneous coronary intervention (PCI. After successful PCI, the patient was immediately taken to the operating room for laparoscopic repair of the perforated viscous. Subsequent to the operative repair, the patient became hemodynamically unstable and a repeat electrocardiogram demonstrated complete right coronary occlusion. Shock ensued and the patient died in the intensive care unit despite this plan of care. It is our opinion that this case reveals the need for expert panels to devise decision algorithms for concomitant presentations of life-threatening diseases.

    Anorexia, nausea, and vomiting are one of the most frequent symptoms in viral hepatitis patients. These may be due to poorly detoxified substances by dysfunctioned hepatocytes or by gastritis, but the pathophysiology is not totally understood. The symptoms interfere with adequate nutrient intake and are managed by metaclopramide, which accelerates gastric emptying. Thus delayed gastric emptying may well be a contributing factor to such symptoms. To determine such a relationship, we measured gastric emptying time in 11 normal subjects, 9 acute (AVH), and 12 chronic B viral hepatitis (CVH) patients. All were males with a mean age of 23 years. An egg was labeled with 0.5 mCi of 99m Tc-sulfur colloid, fried, then eaten between 2 slices of bread with 100 cc of water. Anterior and posterior images were taken at 20 minute intervals over a 2 hour period. A geometric mean of activity pertaining to the gastric region was measured, and T 1 /2 was calculated from the time activity curve. T 1 /2 for normal the group was 57.8 ± 6.3 minutes while that for the AVH and CVH group was 58.2 ± 8.2 (p=0.40) and 64.1 ± 10.5 (p=0.09), respectively. There was 1 AVH patient and 4 CVH patients with prolonged T 1 /2. Anorexia and nausea was seen in 71% and 46% of the patients, respectively. 80% and 60% of the patients with prolonged T 1 /2 had anorexia and nausea, respectively.

    Acute gastric volvulus is a surgical emergency that requires early recognition and treatment. Acute idiopathic mesenteroaxial gastric volvulus is a rare sub-type and there are few cases reported in children and there are even fewer reports in adults. We report a rare case of a 23-year-old man who presented with a 1-day history of vomiting, epigastric pain, distention, and constipation. The diagnosis for mesenteroaxial type gastric volvulus was confirmed by abdominal radiography and computed tomography. The patient was successfully treated by laparotomy with resection of the ischemic stomach wall and anastomosis. Acute spontaneous mesenteroaxial gastric volvulus is rare in adults and early diagnosis is challenging due to non-specific symptoms. A missed or delayed diagnosis may result in serious complications due to gastric obstruction. A patient presenting with severe epigastric pain and clinical evidence of gastric outlet obstruction should be considered as a surgical emergency to rule out gastric volvulus. High index of suspicion, early diagnosis and prompt surgical management are important for favorable outcome in patients with acute spontaneous gastric volvulus.

    Full Text Available Objectives: The gastric ulcer is a common disorder of the stomach and duodenum. The basic physiopathology of a gastric ulcer results from an imbalance between some endogenous aggressive and cytoprotective factors. This study examined whether Ganoderma lucidum pharmacopuncture (GLP would provide protection against acute gastric ulcers in rats. Methods: Sprague-Dawley rats were divided randomly into 4 groups of 8 rats each: normal, control, normal saline (NP and GLP groups. The experimental acute gastric ulcer was induced by using an EtOH/HCl solution and the normal group received the same amount of normal saline instead of ethanol. The NP and the GLP groups were treated once with injections of saline and GLP, respectively. Two local acupoints were used: CV12 (中脘 which is the alarm point of the Stomach Meridian, and ST36 (足三里, which is the sea point of the Stomach Meridian. The stomachs from the rats in each group were collected and analyzed for gross appearance and histology. Also, immunohistochemistry staining for BAX, Bcl-2 and TGF-β1 was performed. Results: Histological observations of the gastric lesions in the control group showed comparatively extensive damage of the gastric mucosa and necrotic lesions had penetrated deeply into the mucosa. The lesions were long, hemorrhagic, and confined to the glandular portions. The lesions were measured microscopically by using the clear depth of penetration into the gastric mucosal surface. The length and the width of the ulcer were measured and the inhibition percentage was calculated. Wound healing of the acute gastric ulcer was promoted by using GLP, and significant alterations of indices in gastric mucosa were observed. Such protection was shown by gross appearance, histology and immunohistochemistry staining for BAX, Bcl-2 and TGF-β1. Conclusion: These results suggest that GLP administered at CV12 and ST36 can provide significant protection to the gastric mucosa against an ethanol

    Full Text Available Congenital diaphragmatic hernia (CDH is the result of the incomplete fusion and closure of the pleuroperitoneal canal during the fetal development. CDH is usually diagnosed prenatally but, if undiagnosed, the clinical presentation ranges from asymptomatic children to serious respiratory or gastrointestinal symptoms. Acute gastric volvulus associated with CDH is a rare surgical emergency in children. We report two cases of acute gastric volvulus associated with CDH and review the literature.

    Perforated gastric cancer is relatively rare and the incidence is reported about 1% of all the cases of gastric cancer. We retrospectively analyzed the clinical data of the consecutive 12 patients with perforated gastric cancer who underwent operation in our hospital between January 2005 and December 2016. There were 5 men and 7 women, with an average age of 65.8 years old(34-87). Perforated gastric cancer occurred in the region U(1 cases), M(6 cases), L(5 cases). There were 11 cases with distant metastasis. We could successfully diagnosed as perforated gastric cancer in 8 cases before emergency operation. Gastrectomy was performed in 5 cases. However, the curative resection was performed only 1 case. Prognosis of perforated gastric cancer is poor. We considered as an appropriate two-step surgical strategy that the first step of surgery is an acute peritonitis treatment followed by radical gastrectomy with lymphadenectomy.

    Full Text Available Gastric volvulus is an abnormal, potentially life-threatening, torsion of the stomach. The presence of complications such as hemoperitoneum increases the diagnostic urgency; however it can also mask the presentation of gastric volvulus. We encountered a 66-year-old female who presented with symptomatic gastric outlet obstruction and was found to have hemoperitoneum and splenic avulsion on imaging. In our case, hemoperitoneum was a clinical red herring as initial imaging concentrated on the presence of hemoperitoneum and was nondiagnostic of gastric volvulus. Interestingly, our patient experienced complete resolution of her presenting symptomatology following placement of a nasogastric tube. Furthermore, endoscopic evaluation revealed no overt pathology to explain outlet obstruction. In light of these findings, gastric torsion was strongly suspected. A repeat CT scan was confirmatory, elucidated reduction of the stomach to its anatomic position, retroactively diagnosing a gastric volvulus. This case is unusual in its presentation and setting. The patient presented with two rare complications of gastric volvulus, hemoperitoneum and splenic avulsion. Additionally, ten years prior to this presentation the patient had a temporary gastrostomy tube. Gastropexy with a gastrostomy is the treatment for gastric volvulus and should have been preventative of her presentation with torsion. Furthermore, the gastric volvulus was not initially recognized radiographically due to the presence of masking radiographic findings. This case serves to highlight the utility of clinical acumen and maintain a high index of suspicion for gastric volvulus in all cases presenting with Borchardt’s triad.

    Gastric volvulus is an uncommon disorder and can present either in the acute or chronic setting with variable symptoms. A robust blood supply of the stomach from different sources does not allow ischemia to develop early. When it occurs in the acute scenario, patients present with severe epigastric pain and retching without vomiting. Together with inability to pass nasogastric tube, they constitute Borchardt's triad. We report a case which presented in the emergency department with severe abdominal pain, abdominal distension and vomiting and a previous history of pulmonary tuberculosis. An incidental finding of uterovaginal prolapse was present. A diagnosis of acute gastric volvulus with peritonitis was made and total gastrectomy with Roux-en-Y esophagojejunostomy for gangrenous and perforated stomach was performed. Primary gastric volvulus occurs in the absence of any defect in the diaphragm or adjacent organ pathology and may be caused by weakening of gastric supports. We wish to highlight if there is a possible association of primary gastric volvulus with uterovaginal prolapse reflecting a general laxity of body ligaments or with fibrosis of the lung secondary to pulmonary tuberculosis resulting into the twisting of the stomach. Acute gastric volvulus is a surgical emergency requiring early diagnosis and aggressive management, as a delay results into complications like gangrene and perforation which substantially increase the morbidity and mortality in these patients.

    Full Text Available Gastric volvulus is a rare and life-threatening condition that involves the abnormal rotation of the stomach around its axis by more than 180°. The association between acute gastric volvulus and atrial fibrillation with rapid ventricular response is rare with only few cases that have been reported. Our patient was an 86-year-old female who presented with upper abdominal pain, distension, nausea, and shortness of breath. Clinical and laboratory workup revealed acute gastric volvulus with diaphragmatic hernia. On presentation, she was also in atrial fibrillation with rapid ventricular response. She was successfully treated by laparotomy with reduction of the gastric volvulus and repair of the diaphragmatic hernia, with significant improvement.

    Full Text Available The protective effect of ginsenoside Re, isolated from ginseng berry, against acute gastric mucosal lesions was examined in rats with a single intraperitoneal injection of compound 48/80 (C48/80. Ginsenoside Re (20 mg/kg or 100 mg/kg was orally administered 0.5 h prior to C48/80 treatment. Ginsenoside Re dose-dependently prevented gastric mucosal lesion development 3 h after C48/80 treatment. Increases in the activities of myeloperoxidase (MPO; an index of neutrophil infiltration and xanthine oxidase (XO and the content of thiobarbituric acid reactive substances (TBARS; an index of lipid peroxidation and decreases in the contents of hexosamine (a marker of gastric mucus and adherent mucus, which occurred in gastric mucosal tissues after C48/80 treatment, were significantly attenuated by ginsenoside Re. The elevation of Bax expression and the decrease in Bcl2 expression after C48/80 treatment were also attenuated by ginsenoside Re. Ginsenoside Re significantly attenuated all these changes 3 h after C48/80 treatment. These results indicate that orally administered ginsenoside Re protects against C48/80-induced acute gastric mucosal lesions in rats, possibly through its stimulatory action on gastric mucus synthesis and secretion, its inhibitory action on neutrophil infiltration, and enhanced lipid peroxidation in the gastric mucosal tissue.

    The effect of gamma irradiation on the gastric mucosa has been studied in a primate model by evaluating endoscopically the rate of healing of gastric biopsies. Six male rhesus monkeys were subjected to fiberoptic gastroscopies performed under general anesthesia before and after total body exposure to Cobalt-60 (800 rads). Gastric biopsies were taken 3 hours and 2, 7, and 9 days after irradiation and examined using light microscopy. Gastric biopsies were found to heal in 3 days before irradiation; in contrast, they were still present 7 and 9 days after the biopsies in irradiated animals. Microscopic examination of the biopsies taken outside of the ulcer craters did not demonstrate any significant changes of the gastric surface epithelial cells. These data demonstrate that a gastric ulcer develops at the site of each endoscopic biopsy in irradiated monkeys whereas complete healing is observed in non-irradiated animals. The cause of this observation is unclear but it could be due to radiation induced suppression of the mitotic activity and of the cell renewal of gastric surface epithelial cells

    Gastric volvulus can be classified according to etiology as primary or secondary, according to anatomy as or mesenteroaxial, and according to onset as acute or chronic. Management of secondary gastric volvulus acute should always be surgery and the choice of surgical procedure for treatment is chosen according to etiology. Adherolysis and extraction of foreign bodies (suture, mesh, and gastric band) are important in those cases associated with previous abdominal surgery. Nissen fundoplication is a safe and effective procedure. Severe late complications of laparoscopic Nissen fundoplication are extremely rare occurrences. Among the reported complications is gastric volvulus. Presentation of two cases and review of literature. Two cases of acute gastric volvulus secondary to laparoscopic Nissen fundoplication presenting with epigastric pain and nonproductive retching and treated by laparoscopy are described. Symptoms upon presentation, incidence, diagnosis, treatment and predisposing factors to gastric volvulus postfundoplication are discussed. Gastric volvulus rarely occurs as a complication of Nissen fundoplication with an incidence similar to others of late complications. The described mechanisms that originate gastric volvulus postfundoplication are related to adhesions, foreign bodies as suture (polyester), gastrostomy tubes and mesh, gastropexy and internal gastric herniation through a "transfundoplication" window. A high index of suspicion is required in those patients presenting with acute symptoms of gastric obstruction in the first year following laparoscopic Nissen fundoplication. Laparoscopic approach is safe with or without gastropexy, always correcting the underlying mechanisms that cause gastric volvulus.

    Acute gastric dilation is a rare but recognised complication in patients with bulimia and anorexia following binge episodes owing to decreased bowel motility. We present a rare case of acute gastric dilation secondary to bulimia in an otherwise healthy 18-year-old female patient that resulted in compression and complete occlusion of the abdominal aorta, leading to acute mesenteric and bilateral lower limb ischaemia. This resolved immediately following a laparotomy and gastric decompression. Management of these patients is very challenging owing to the lack of a successful precedent. To our knowledge, such a catastrophic complication has only ever been reported once in the literature and the outcome was fatal. Our case is of additional importance as it offers a successful management strategy for these patients.

    Treatment of gastric ulcers with medicinal plants is quite common in traditional medicine worldwide. Cymbopogon citratus (DC) Stapf. leaves infusion has been used in folk medicine of many tropical and subtropical regions to treat gastric disturbances. The aim of this study was to assess the potential gastroprotective activity of an essential oil-free infusion from C. citratus leaves in acute gastric lesions induced by ethanol in rat. The study was performed on adult male Wistar rats (234.0±22.7g) fasted for 24h but with free access to water. The extract was given orally before (prevention) or after (treatment) intragastric administration of absolute ethanol. Effects of dose (28 or 56mg/kg of body weight) and time of contact of the extract with gastric mucosa (1 or 2h) were also assessed. Animals were sacrificed, being the stomachs removed and the lesions were assessed by macroscopic observation and histopathology. C. citratus extract, given orally before or after ethanol, significantly (P<0.01) reduced gastric mucosal injury compared with control group (vehicle+ethanol). The effect does not appear to be dose-dependent. Results also suggested that the extract is more effective when the time of contact with gastric mucosa increases. The results of this assay confirm the gastroprotective activity of C. citratus extract on experimental gastric lesions induced by ethanol, contributing for the pharmacological validation of its traditional use.

    Anisakiasis is an emerging zoonosis caused by the fish parasitic nematode Anisakis. Spain appears to have the highest reported incidence in Europe and marinated anchovies are recognised as the main food vehicle. Using data on fishery landings, fish infection rates and consumption habits of the Spanish population from questionnaires, we developed a quantitative risk assessment (QRA) model for the anchovy value chain. Spaniards were estimated to consume on average 0.66 Anisakis per untreated (non-frozen) raw or marinated anchovy meal. A dose-response relationship was generated and the probability of anisakiasis was calculated to be 9.56 × 10-5 per meal, and the number of annual anisakiasis cases requiring medical attention was predicted between 7,700 and 8,320. Monte Carlo simulations estimated post-mortem migration of Anisakis from viscera to flesh increases the disease burden by >1000% whilst an education campaign to freeze anchovy before consumption may reduce cases by 80%. However, most of the questionnaire respondents who ate untreated meals knew how to prevent Anisakis infection. The QRA suggests that previously reported figures of 500 anisakiasis per year in Europe is a considerable underestimate. The QRA tool can be used by policy makers and informs industry, health professionals and consumers about this underdiagnosed zoonosis.

    In pathological situations, such as acute myocardial infarction, disorders of motility of the proximal gut can trigger symptoms like nausea and vomiting. Acute myocardial infarction delays gastric emptying (GE) of liquid in rats. Investigate the involvement of the vagus nerve, α 1-adrenoceptors, central nervous system GABA B receptors and also participation of paraventricular nucleus (PVN) of the hypothalamus in GE and gastric compliance (GC) in infarcted rats. Wistar rats, N = 8-15 in each group, were divided as INF group and sham (SH) group and subdivided. The infarction was performed through ligation of the left anterior descending coronary artery. GC was estimated with pressure-volume curves. Vagotomy was performed by sectioning the dorsal and ventral branches. To verify the action of GABA B receptors, baclofen was injected via icv (intracerebroventricular). Intravenous prazosin was used to produce chemical sympathectomy. The lesion in the PVN of the hypothalamus was performed using a 1mA/10s electrical current and GE was determined by measuring the percentage of gastric retention (% GR) of a saline meal. No significant differences were observed regarding GC between groups; vagotomy significantly reduced % GR in INF group; icv treatment with baclofen significantly reduced %GR. GABA B receptors were not conclusively involved in delaying GE; intravenous treatment with prazosin significantly reduced GR% in INF group. PVN lesion abolished the effect of myocardial infarction on GE. Gastric emptying of liquids induced through acute myocardial infarction in rats showed the involvement of the vagus nerve, alpha1- adrenergic receptors and PVN

    To describe the presence of heterotopic gastric mucosa forming an abscess associated with acute abdominal pain and shock in a puppy. A 7-month-old male intact Shih-Tzu was presented to the emergency service for evaluation of a 12-hour history of vomiting and lethargy progressing to weakness. On presentation, the puppy was obtunded and hypotensive. Radiographs revealed an ill-defined mid-ventral abdominal mass. Ultrasound revealed an echogenic, fluid-filled mass associated with the jejunum. The puppy had an exploratory celiotomy and a 2 × 4 cm oval fluid-filled soft tissue mass was found to be intimately associated, but not communicating with, a section of the mid-jejunum. The mass and associated jejunum were removed via enterectomy. Histopathology of the resected mass revealed heterotopic gastric mucosa; bacterial culture of the fluid contained in the mass revealed heavy growth of Escherichia coli. The puppy recovered from surgery, was discharged from the hospital, and has had no further complications from this episode. Heterotopic gastric mucosa is commonly found incidentally on necropsy. When it has been associated with acute gastrointestinal signs, mechanical intestinal obstruction with or without perforation was noted. To the authors' knowledge, this is the first reported case of heterotopic gastric mucosa leading to abscess formation and acute abdominal pain in the dog. © Veterinary Emergency and Critical Care Society 2014.

    Conyza blinii H.Lév., is a type of natural plant. Its dried overground section is used to treat infections and inflammations in traditional Chinese medicine. Triterpenoidal saponins have a wide range of bioactivities, for instance, anti-cancer, anti-virus and anti-anaphylaxis. Conyza blinii saponin (CBS), mainly composed of triterpenoidal saponins, is the total saponin of Conyza blinii H.Lév. It has been reported that CBS also has gastric mucous membrane protection activity. This study aims to test CBS׳s protective activity of gastric׳s mucous membrane against ethanol. This investigation may lead to the development of novel drug from natural products as anti-ulcer agent, or as gastric mucous protective against chemical damage. CBS (Conyza blinii saponin) is the total saponin of Conyza blinii H.Lév., which was obtained as described previously. We tested the protective activity of CBS against ethanol-induced ulcer. Thirty six rats were grouped randomly as 'NORMAL', 'CONTROL', 'MODEL', 'LOW DOSE', 'MEDIUM DOSE' and 'HIGH DOSE'. The 'NORMAL' group were rats with no pathological model established within it. The 'CONTROL' group was administrated with colloidal bismuth subcitrate, while 'MODEL' group was not given any active agents apart from absolute ethanol in order to obtain gastric ulcer model. The three 'DOSE' groups were treated with different concentrations of CBS (5, 10, 20mg/mL) before administration followed by absolute ethanol. All rats were sacrificed after the experiment to acquire the gastric tissue. The ulcer index (UI), malondialdehyde (MDA) and superoxide dismutase (SOD) were measured to monitor the activity of CBS. Besides, the rat gastric tissue was made to paraffin section and stained using the Hematoxylin-Eosin (HE) method. The histopathology examination was carried out to examine CBS efficacy in terms of gastric mucous protection. We found that CBS had a profound protection activity against acute gastric ulcer induced by ethanol and this

    Full Text Available Transcutaneous intraluminal impedance measurement (TIIM is a new method to cutaneously measure gastric contractions by assessing the attenuation dynamics of a small oscillating voltage emitted by a battery-powered ingestible capsule retained in the stomach. In the present study, we investigated whether TIIM can reliably assess gastric motility in acute canine models. Methods. Eight mongrel dogs were randomly divided into 2 groups: half received an active TIIM pill and half received an identically sized sham capsule. After 24-hour fasting and transoral administration of the pill (active or sham, two force transducers (FT were sutured onto the antral serosa at laparotomy. After closure, three standard cutaneous electrodes were placed on the abdomen, registering the transluminally emitted voltage. Thirty-minute baseline recordings were followed by pharmacological induction of gastric contractions using neostigmine IV and another 30-minute recording. Normalized one-minute baseline and post-neostigmine gastric motility indices (GMIs were calculated and Pearson correlation coefficients (PCCs between cutaneous and FT GMIs were obtained. Statistically significant GMI PCCs were seen in both baseline and post-neostigmine states. There were no significant GMI PCCs in the sham capsule test. Further chronic animal studies of this novel long-term gastric motility measurement technique are needed before testing it on humans.

    Gastric volvulus (GV) is a rare and life threatening condition if not treated promptly or wrongly diagnosed. The main complication of gastric volvulus is foregut obstruction. The extreme rotation can cut off blood supply to the stomach and even distal organs, which can lead to ischemia and necrosis of the affected area. We report a case of a 41yo female that complained of severe abdominal pain, nausea and vomiting for approximately 3days after eating a large meal. The patient didn't have any flatus or bowel movements in the last 24h. CT of the abdomen and pelvis showed a dilatation of the stomach and esophageal hernia. Laparotomy confirmed an organoaxial volvulus at the level of the antrum and body of the stomach. Gastropexy was implemented and the stomach fixed to the posterior abdominal wall to prevent recurrence. GV may have a significant related morbidity and mortality rate. It can be missed easily on diagnosis. The presence of vomiting not responding to initial antiemetic treatment, as well as, the presence of a hiatal hernia on the imaging studies should trigger our thinking of gastric volvulus, regardless of the stable appearance of the patient. Chronic GV can manifests as atypical chest, abdomen and gastro intestinal symptoms. We recommend that everyone with these atypical symptoms seek medical attention to rule out GV. Early diagnosis and treatment will reduce the risk of developing chronic gastric volvulus to acute gastric volvulus. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Acute massive gastric dilatation (AMGD) is a rare distinctive condition but associates with high morbidity and mortality. Though usually seen in patients with eating disorders, many aetiologies of AMGD have been described. The distension has been reported to cause gastric necrosis with or without perforation, usually within 1-2 days of an inciting event of AMGD.We report the case of a 58-year-old male who presented with gastric perforation associated with AMGD 11 days after surgical relief of a proximal small bowel obstruction. The AMGD arose from a closed loop obstruction between a tumour at the gastro-oesophageal junction and a small bowel obstruction as a result of volvulus around a jejunal feeding tube.To our knowledge, this is the first case of a closed loop obstruction of this aetiology reported in the literature, and the presentation of this patient's AMGD was notable for the delayed onset of gastric necrosis. The patient underwent an exploratory laparotomy and a partial gastrectomy to excise a portion of his perforated stomach. Surgeons should be aware of the possibility of delayed ischaemic gastric perforation in cases of AMGD. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    2011-05-01

    Full Text Available Acute intrathoracic gastric volvulus occurs when the stomach undergoes organoaxial torsion in the chest due to either concomitant enlargement of the hiatus or a diaphragmatic hernia. Iatrogenic diaphragmatic hernia can occur after hiatal hernia repair and other surgical procedures, such as nephrectomy, esophagogastrectomy and splenopancreatectomy. We describe a 49-year-old woman who presented to our emergency department with acute moderate epigastric soreness and vomiting. She had undergone extensive gynecologic surgery including splenectomy 1 year before. The chest radiograph obtained in the emergency department demonstrated an elevated gastric air-fluid level in the left lower lung field. An urgent gastroscopy showed twisted structural abnormality of the stomach body. A computed tomography scan demonstrated the distended stomach, located in the left lower hemithorax through a left diaphragmatic defect. Emergent transthoracic repair was performed. Postoperative recovery was uneventful, and the patient did not experience any pain or difficulty with eating.

    The protective activity of prickly pear cactus (Opuntia ficus indica var. saboten) fruit juice and its main constituent, betanin, were evaluated against stress-induced acute gastric lesions in rats. After 6 h of water immersion restraint stress (WIRS), gastric mucosal lesions with bleeding were induced in Sprague-Dawley rats. Pretreatment of a lyophilized powder containing O. ficus indica var. saboten fruit juice and maltodextrin (OFSM) and betanin significantly reduced stress lesions (800-1600 mg/kg). Both OFSM and betanin effectively prevented the decrease in gastric mucus content as detected by alcian blue staining. In addition, OFSM significantly suppressed WIRS-induced increases in the level of gastric mucosal tumor necrosis factor-α and myeloperoxidase (MPO). Betanin alone was only effective in decreasing MPO. These results revealed the protective activity of OFSM against stress-induced acute gastric lesions and that betanin may contribute to OFSM's gastric protective activity, at least in part. When OFSM and betanin were taken together, OFSM exerted gastroprotective activity against stress-induced gastric lesions by maintaining gastric mucus, which might be related to the attenuation of MPO-mediated damage and proinflammatory cytokine production.

    Full Text Available We report three infants who presented with acute gastric volvulus and recovered initially after de-torsion, but later presented with sequelae due to ischemia of gastroesophageal junction, stomach and gastroduodenal junction. The first two infants could not be fed orally or by gastrostomy tube because of microgastria and stricture of the lower esophagus and gastroduodenal junction, and were managed on jejunostomy feeds, while the third child was managed on gastrostomy feeds till the gastric substitution surgery. The first case was treated nonsurgically with repeated dilatations, but ultimately succumbed to sepsis and malnutrition. In the second child, attempted dilatation resulted in esophageal perforation and she was reconstructed using ileocecal segment as a substitute for stomach and lower esophagus, and has done well. The third child was managed surgically by the Hunt Lawrence J pouch as stomach substitute and has also done well.

    Full Text Available We have observed that acute blood volume expansion increases the gastroduodenal resistance to the flow of liquid in anesthetized dogs, while retraction decreases it (Santos et al. (1991 Acta Physiologica Scandinavica, 143: 261-269. This study evaluates the effect of blood volume expansion and retraction on the gastric emptying of liquid in awake rats using a modification of the technique of Scarpignato (1980 (Archives Internationales de Pharmacodynamie et de Therapie, 246: 286-294. Male Wistar rats (180-200 g were fasted for 16 h with water ad libitum and 1.5 ml of the test meal (0.5 mg/ml phenol red solution in 5% glucose was delivered to the stomach immediately after random submission to one of the following protocols: 1 normovolemic control (N = 22, 2 expansion (N = 72 by intravenous infusion (1 ml/min of Ringer-bicarbonate solution, volumes of 1, 2, 3 or 5% body weight, or 3 retraction (N = 22 by controlled bleeding (1.5 ml/100 g. Gastric emptying of liquid was inhibited by 19-51.2% (P<0.05 after blood volume expansion (volumes of 1, 2, 3 or 5% body weight. Blood volume expansion produced a sustained increase in central venous pressure while mean arterial pressure was transiently increased during expansion (P<0.05. Blood volume retraction increased gastric emptying by 28.5-49.9% (P<0.05 and decreased central venous pressure and mean arterial pressure (P<0.05. Infusion of the shed blood 10 min after bleeding reversed the effect of retraction on gastric emptying. These findings suggest that gastric emptying of liquid is subject to modulation by the blood volume.

    Full Text Available The impact of acute volume imbalances on gastric volume (GV was studied in anesthetized rats (250-300 g. After cervical and femoral vessel cannulation, a balloon catheter was positioned in the proximal stomach. The opposite end of the catheter was connected to a barostat with an electronic sensor coupled to a plethysmometer. A standard ionic solution was used to fill the balloon (about 3.0 ml and the communicating vessel system, and to raise the reservoir liquid level 4 cm above the animals' xiphoid appendix. Due to constant barostat pressure, GV values were considered to represent the gastric compliance index. All animals were monitored for 90 min. After a basal interval, they were randomly assigned to normovolemic, hypervolemic, hypovolemic or restored protocols. Data were compared by ANOVA followed by Bonferroni's test. Mean arterial pressure (MAP, central venous pressure (CVP and GV values did not change in normovolemic animals (N = 5. Hypervolemic animals (N = 12 were transfused at 0.5 ml/min with a suspension of red blood cells in Ringer-lactate solution with albumin (12.5 ml/kg, which reduced GV values by 11.3% (P0.05. MAP and CVP values increased (P<0.05 after hypervolemia but decreased (P<0.05 with hypovolemia. In conclusion, blood volume level modulates gastric compliance, turning the stomach into an adjustable reservoir, which could be part of the homeostatic process to balance blood volume.

    Therapy against anisakiasis requires invasive techniques to extract L3 , and an effective drug against this nematode is needed. The aim of this study was to determine the efficacy of peppermint essential oil (EO) and its main components against the parasite in comparison to albendazole, a drug currently prescribed to treat anisakiasis. We conducted in vitro experiments and studied an experimental model simulating the human infection in Wistar rats. We used polymerase chain reaction restriction fragment length polymorphism to identify A. simplex s.s. and A. pegreffii and determine any differences in their pathogenicity and susceptibility to the treatments. The in vitro and in vivo experiments both showed that the larvicidal activity of peppermint EO, menthol, menthone and menthyl acetate is higher than that of albendazole. Large stomach lesions were observed in 46.7% of the albendazole-treated rats, whereas no gastrointestinal lesions were detected in those treated with peppermint EO, menthol, menthyl acetate or menthone. In this animal model, treatment with peppermint EO or its main components was more effective than was treatment with albendazole. Lesions were more frequently produced by A. simplex s.s. larvae than by A. pegreffii larvae. © 2014 John Wiley & Sons Ltd.

    Full Text Available Background/AimsThe most appropriate treatment for acute gastric variceal bleeding (GVB is currently endoscopic gastric variceal obturation (GVO using Histoacryl®. However, the secondary prophylactic efficacy of beta-blocker (BB after GVO for the first acute episode of GVB has not yet been established. The secondary prophylactic efficacy of BB after GVO for the first acute episode of GVB was evaluated in this study.MethodsNinety-three patients at Soonchunhyang University Hospital with acute GVB who received GVO using Histoacryl® were enrolled between June 2001 and March 2010. Among these, 42 patients underwent GVO alone (GVO group and 51 patients underwent GVO with adjuvant BB therapy (GVO+BB group. This study was intended for patients in whom a desired heart rate was reached. The rates of rebleeding-free survival and overall survival were calculated for the two study groups using Kaplan-Meyer analysis and Cox's proportional-hazards model.ResultsThe follow-up period after the initial eradication of gastric varices was 18.14±25.22 months (mean±SD. During the follow-up period, rebleeding occurred in 10 (23.8% and 21 (41.2% GVO and GVO+BB patients, respectively, and 39 patients died [23 (54.8% in the GVO group and 16 (31.4% in the GVO+BB group]. The mean rebleeding-free survival time did not differ significantly between the GVO and GVO+BB groups (65.40 and 37.40 months, respectively; P=0.774, whereas the mean overall survival time did differ (52.54 and 72.65 months, respectively; P=0.036.Conclusions Adjuvant BB therapy after GVO using Histoacryl® for the first acute episode of GVB could decrease the mortality rate relative to GVO alone. However, adjuvant BB therapy afforded no benefit for the secondary prevention of rebleeding in GV.

The gastroprotective effect of C. barometz leaves against ethanol-induced gastric hemorrhagic abrasions in Sprague Dawley rats has been evaluated in terms of medicinal properties. Seven groups of rats (normal control and ulcerated control groups, omeprazole 20 mg/kg, 62.5, 125, 250, and 500 mg/kg of C. barometz correspondingly were used in antiulcer experiment and pretreated with 10% Tween 20. After 1 hour, the normal group was orally administered 10% Tween 20, whereas absolute alcohol was fed orally to ulcerated control, omeprazole, and experimental groups. Gastric’s homogenate were assessed for endogenous enzymes activities. Stomachs were examined macroscopically and histologically. Grossly, the data demonstrated a significant decrease in the ulcer area of rats pretreated with plant extract in a dose-dependent manner with respect to the ulcerated group.

    A 43-year-old female was referred to our hospital for sudden onset of abdominal pain, fullness, and vomiting. Physical examination revealed abdominal distension with mild epigastric tenderness. Abdominal radiography showed massive gastric distension and plain computed tomography (CT) a markedly enlarged stomach filled with gas and fluid. A large volume of gastric contents was suctioned out via a nasogastric (NG) tube. Contrast-enhanced CT showed a grossly distended stomach with displacement of the antrum above the gastroesophageal junction, and the spleen was dislocated inferiorly. Upper gastrointestinal (GI) series showed the greater curvature to be elevated and the gastric fundus to be lower than normal. Acute mesenteroaxial gastric volvulus was diagnosed. GI endoscopy showed a distortion of the gastric anatomy with difficulty intubating the pylorus. Various endoscopic maneuvers were required to reposition the stomach, and the symptoms showed immediate and complete solution. GI fluoroscopy was performed 3 days later. Initially, most of the contrast medium accumulated in the fundus, which was drawn prominently downward, and then began flowing into the duodenum with anteflexion. Elective laparoscopic surgery was performed 1 month later. The stomach was in its normal position, but the fundus was folded posteroinferiorly. The spleen attached to the fundus was normal in size but extremely mobile. We diagnosed a wandering spleen based on the operative findings. Gastropexy was performed for the treatment of gastric volvulus and wandering spleen. The patient remained asymptomatic, and there was no evidence of recurrence during a follow-up period of 24 months. This report describes a rare adult case of acute gastric volvulus associated with wandering spleen. Because delay in treatment can result in lethal complications, it is critical to provide a prompt and correct diagnosis and surgical intervention. We advocate laparoscopic surgery after endoscopic reduction because

    To explore the clinical efficacy of early application of sequential gastrointestinal lavage in patients with acute paraquat poisoning by analyzing the clinical data of 97 patients. A total of 97 eligible patients with acute paraquat poisoning were divided into conventional treatment group (n = 48) and sequential treatment group (n = 49). The conventional treatment group received routine gastric lavage with water. Then 30 g of montmorillonite powder, 30 g of activated charcoal, and mannitol were given to remove intestinal toxins once a day for five days. The sequential treatment group received 60 g of montmorillonite powder for oral administration, followed by small-volume low-pressure manual gastric lavage with 2.5%bicarbonate liquid. Then 30 g of activated charcoal, 30 g of montmorillonite powder, and polyethylene glycol electrolyte lavage solution were given one after another for gastrointestinal lavage once a day for five days. Both groups received large doses of corticosteroids, blood perfusion, and anti-oxidation treatment. The levels of serum potassium, serum amylase (AMY) alanine aminotransferase (ALT), total bilirubin (TBIL), blood urea nitrogen (BUN), creatinine (Cr), lactate (Lac), and PaO₂of patients were determined at 1, 3, 5, 7, and 10 days. Laxative time, mortality, and survival time of dead cases were evaluated in the two groups. The incidence rates of hypokalemia (110 U/L) were significantly lower in the sequential treatment group than in the conventional treatment group (P 80 U/L), TBIL (>34.2 µmol/L), BUN (>7.2 mmol/L), and Cr (>177 µmol/L) between the two groups (P>0.05). However, the highest levels of ALT, TBIL, BUN, Cr, and Lac were significantly lower in the sequential treatment group than in the conventional treatment group (P treatment group had significantly lower incidence of PaO₂(treatment group (P poisoning.

  1. Gastric Lavage in Acute Organophosphorus Pesticide poisoning (GLAOP – a randomised controlled trial of multiple vs. single gastric lavage in unselected acute organophosphorus pesticide poisoning

    Full Text Available Abstract Background Organophosphorus (OP pesticide poisoning is the most common form of pesticide poisoning in many Asian countries. Guidelines in western countries for management of poisoning indicate that gastric lavage should be performed only if two criteria are met: within one hour of poison ingestion and substantial ingested amount. But the evidence on which these guidelines are based is from medicine overdoses in developed countries and may be irrelevant to OP poisoning in Asia. Chinese clinical experience suggests that OP remains in the stomach for several hours or even days after ingestion. Thus, there may be reasons for doing single or multiple gastric lavages for OP poisoning. There have been no randomised controlled trials (RCTs to assess this practice of multiple lavages. Since it is currently standard therapy in China, we cannot perform a RCT of no lavage vs. a single lavage vs. multiple lavages. We will compare a single gastric lavage with three gastric lavages as the first stage to assess the role of gastric lavage in OP poisoning. Methods/Design We have designed an RCT assessing the effectiveness of multiple gastric lavages in adult OP self-poisoning patients admitted to three Chinese hospitals within 12 hrs of ingestion. Patients will be randomised to standard treatment plus either a single gastric lavage on admission or three gastric lavages at four hour intervals. The primary outcome is in-hospital mortality. Analysis will be on an intention-to-treat basis. On the basis of the historical incidence of OP at the study sites, we expect to enroll 908 patients over three years. This projected sample size provides sufficient power to evaluate the death rate; and a variety of other exposure and outcome variables, including particular OPs and ingestion time. Changes of OP level will be analyzed in order to provide some toxic kinetic data. Discussion the GLAOP study is a novel, prospective cohort study that will explore to the toxic

    INTRODUCTION: Impaired secretion of glucagon-like peptide 1 (GLP-1) has been suggested to contribute to the deficient incretin effect in patients with type 2 diabetes. It is unclear whether this is a primary defect or a consequence of the hyperglycemia in type 2 diabetes. We examined whether acute...... hyperglycemia reduces the postprandial excursions of gastric inhibitory polypeptide (GIP) and GLP-1, and if so, whether this can be attributed to changes in gastric emptying.

    The aim of the present case study is to raise concern on the proper diagnostic approach of acute gastric volvulus (AGV) cases, in which, the key issue is the timely diagnosis and the prompt therapeutic intervention. After thorough and systematic research of the current literature, it is concluded that early diagnosis remains challenging, while there is no relevant publication with emphasis on the contribution of ultrasonography to the diagnostic documentation of AGV. A 6 years old boy was admitted to our Department due to repeatedly non bilious vomiting and food refusal during the last 72 hours before admission. Physical examination revealed the presence of a spherical, painful mass in the epigastrium, which did not recede a er placement of a nasogastric tube. Abdominal radiography showed the presence of a large gastric air bubble. Ultrasonography highlighted a distended and fluid-filled stomach, which was displaced in a cephalic position compared to esophagus and a pylorus pointing downward, in a cranial caudal orientation. Following barium meal examination confirmed the diagnosis of gastric volvulus. Patient underwent an urgent exploratory laparotomy, revealing the presence of acute mesenteroaxial gastric volvulus with a serosal ecchymosis in the major arc. After restoration of the gastric volvulus, thorough intraoperative investigation on the existence of a subject cause followed. Presence of relaxation of stomach's ligaments was finally documented. Fixation of the stomach' fundus to the diaphragm and anterior gastropexy were then conducted. Postoperative period was uneventful and the patient was discharged home on the 4th postoperative day. In conclusion, we believe that ultrasonography plays a significant role in the diagnostic approach of acute gastric volvulus, as it has the potential to detect findings suggestive of the diagnosis. Once the diagnosis is suspected on ultrasonography, contrast series should be performed, without further delay, in order to con

    Acute gastric volvulus associated with congenital diaphragmatic hernia is an unusual surgical emergency. We describe a case of an 11-year-old girl who presented with a 4-day history of abdominal pain, nonproductive retching, cough, and shortness of breath. A chest radiograph revealed a large air-fluid level in left hemithorax and the presence of intestinal loops with marked mediastinal deviation. Nasogastric decompression was unsuccessful. Via a thoracoscopic approach, the large fluid-filled stomach was percutaneously decompressed but could not be reduced. Through a left subcostal incision, a left-sided diaphragmatic defect about 4 x 5 cm was encountered. A large portion of small intestines, ascending and transverse colon, strangulated but viable stomach, and a large spleen herniated through the defect. The contents were reduced, revealing a combined gastric volvulus. Once the diaphragmatic defect was repaired primarily, there was insufficient space in the abdominal cavity to contain all the viscera reduced form the chest. Therefore, we placed an AlloDerm patch on the fascia and closed with a wound V.A.C (Kinetic Concepts Inc, San Antonio, TX). Two weeks later, the wound was definitively closed; she recovered uneventfully and was discharged home 3 days later. To our knowledge, only 26 previous cases of acute gastric volvulus complicating a congenital diaphragmatic hernia in children have been reported in the literature. Our patient represents the 27th case and the first combined type acute gastric volvulus case.

    Neural gastric electrical stimulation (NGES) is a new method for invoking gastric contractions under microprocessor control. However, optimization of this technique using feedback mechanisms to minimize power consumption and maximize effectiveness has been lacking. The present pilot study proposes a prototype feedback-controlled neural gastric electric stimulator for the treatment of obesity. Both force-based and inter-electrode impedance-based feedback neurostimulators were implemented and tested. Four mongrel dogs (2 M, 2 F, weight 14.9 ± 2.3 kg) underwent subserosal implantation of two-channel, 1 cm, bipolar electrode leads and two force transducers in the distal antrum. Two of the dogs were stimulated with a force feedback system utilizing the force transducers, and the other two animals were stimulated utilizing an inter-electrode impedance-based feedback system utilizing the proximal electrode leads. Both feedback systems were able to recognize erythromycin-driven contractions of the stomach and were capable of overriding them with NGES-invoked retrograde contractions which exceeded the magnitudes of the erythromycin-driven contractions by an average of 100.6 ± 33.5% in all animals. The NGES-invoked contractions blocked the erythromycin-driven contractions past the proximal electrode pair and induced temporary gastroparesis in the vicinity of the distal force transducer despite the continuing erythromycin infusion. The amplitudes of the erythromycin-invoked contractions in the vicinity of the proximal force transducer decreased abruptly by an average of 47.9 ± 6.3% in all four dogs after triggering-invoked retrograde contractions, regardless of the specific feedback-controlled mechanism. The proposed technique could be helpful for retaining food longer in the stomach, thus inducing early satiety and diminishing food intake

  11. Acute gastric dilatation and volvulus in a free-living polar bear

    Amstrup, Steven C.; Nielsen, Carol A.

    1989-01-01

    A large, adult male polar bear (Ursus maritimus) was found dead on a barrier island north of Prudhoe Bay, Alaska (USA), in June 1987. There were no external signs of trauma. A twisted distended stomach, distinctive parenchymal and fascial congestion, and significant difficulty in repositioning the anterior abdominal organs, indicated that gastric dilatation-volvulus (GDV) was the proximate cause of death. Polar bears frequently consume large quantities of food at one time and have large stomachs that are well adapted to periodic gorging. The scarcity of food in winter and early spring, combined with voluntary fasting and protracted vigorous activity during the breeding season in late spring may have predisposed this bear to GDV. The relationship between GDV and postprandial exercise emphasizes the need for a better understanding of how the present human invasion of arctic habitats may influence polar bear activities.

    Full Text Available ObjectiveTo investigate the effect and safety of endoscopic injection of cyanoacrylate in the treatment of esophageal and gastric variceal bleeding (EGVB in children. MethodsThe clinical data of 35 children with acute EGVB who were treated with endoscopic injection of cyanoacrylate in Children′s Hospital of Baoji Maternal and Child Health Care Hospital from August 2010 to August 2015 were analyzed retrospectively. The emergency response rate, rebleeding rate, and incidence of complications after the treatment were analyzed statistically. ResultsThirty-five patients received 46 times of endoscopic injection of cyanoacrylate in total. The response rate to the initial injection was 95.6% (44/46. The volume of cyanoacrylate injected was 0.2-0.6 ml, with a mean volume of 0.4±0.2 ml. The emergency hemostasis rate was 93.4% (43/46, the rebleeding rate was 11.4% (4/35, and the cycle for 4 patients with the recurrence of bleeding to be cured was 1.2-23.0 months (mean 121±10.9 months. One patient experienced abdominal pain, and no patients experienced ectopic embolism. Two patients died after injection. ConclusionFrequent, small-volume endoscopic injection of cyanoacrylate is an effective and convenient therapeutic method for EGVB in children, has few complications, and holds promise for clinical application.

    To investigate whether compression of the superior mesenteric vein (SMV) on computed tomography (CT) can serve as a valid sign of internal herniation (IH) in patients with antecolic laparoscopic Roux-en-Y gastric bypass (LRYGBP). With institutional review board approval, we performed a retrospective analysis of 41 patients with antecolic LRYGBP referred for acute CT of the abdomen with suspicion of IH or another cause of acute abdomen. CT scans were randomly reviewed for signs of IH by two radiologists in a blinded manner, and the findings were correlated with the results of the patients' bariatric workup. Sensitivity, specificity, and inter-observer agreement were calculated for each sign. Five patients were classified as having intermittent IH and were excluded. Eighteen patients were found to have IH at laparoscopy and served as the study group; 18 patients served as the control group. SMV compression had the best sensitivity (67 % for both reviewers) and inter-observer agreement (kappa = 0.82) of all investigated signs. The swirl sign showed a lower sensitivity (39 and 50 % respectively) and kappa (0.37). SMV compression is a reliable sign of IH in patients with antecolic LRYGBP. circle CT can help detect internal herniation after laparoscopic Roux-en-Y gastric bypass. (orig.)

Most patients who experience gastric volvulus present with mild or intermittent gastric obstructive symptoms. However, severe acute gastric volvulus can result in complete gastric outlet obstruction and ischemia. Consequently, acute gastric volvulus warrants immediate evaluation and management. The goals of management are to relieve the obstruction and prevent recurrent volvulus. Techniques to manage gastric volvulus depend on patient characteristics and the presence of gastric ischemia. In the absence of gastric ischemia, gastric volvulus can be managed with anterior abdominal wall gastropexy or paraesophageal hernia repair. If gastric ischemia is present, operative resection of the affected portion of the stomach is indicated. When operative management is indicated, many patients with gastric volvulus can be managed with minimally invasive (laparoscopic, endoscopic, or laparoendoscopic techniques.

    Full Text Available The compound dichlorido-copper(II-4-(2-5-bromobenzylideneaminoethyl piperazin-1-ium phenolate (CuLBS was synthesized, characterized and screened for acute toxicity and protective activity against ethanol-induced gastric mucosal injury in rats. Gross microscopic lesions, biochemical and immunological parameters and histochemcial staining of glycogen storage were taken into consideration. Oral administration of CuLBS (30 and 60 mg/Kg for two weeks dose-dependently flattened gastric mucosa, significantly increased gastric mucus and total acidity, compared with control group (P < 0.01. Serum levels of liver enzymes aspartate (AST and alanine transaminases (ALT, pro-inflammatory (IL-6 and TNF-α and anti-inflammatory (IL-10 cytokines in the rats exposed to ethanol induced ulceration have been altered. Administration of CuLBS showed considerable (P < 0.05 protection against ulceration by modulating the acute alterations of cytokines AST, ALT and stomach glycogen. Interestingly, CuLBS did not interfere with the natural release of nitric oxide. CuLBS alone (60 mg/Kg did not exhibit any ulcerogenic effect as assessed using Adami’s scoring scale. An acute toxicity study showed that rats treated with CuLBS (1,000 and 2,000 mg/Kg manifested no abnormal signs. These findings therefore, suggested that the gastroprotective activity of CuLBS might contribute in modulating the inflammatory cytokine-mediated oxidative damage to gastric mucosa.

    Massive hemoptysis is a life-threatening condition, and the major source of bleeding in this condition is the bronchial circulation. Bronchial artery embolization is a safe and effective treatment for controlling hemoptysis. However, the sites of origin of the bronchial arteries (BAs) have numerous anatomical variations, which can result in a technical challenge to identify a bleeding artery. We present a rare case of a left inferior BA that originated from the left gastric artery in a patient with recurrent massive hemoptysis caused by bronchiectasis. The aberrant BA was embolized, and hemoptysis has been controlled for 8 months

Benth. in a ratio of 6:1 (w/w and was first recorded in “Danxi’s experiential therapy” for treating gastrointestinal disorders in the 15th century. However, the poor solubility of alkaloids from ZJP restricted the protective effect in treating gastritis and gastric ulcer. The aim of the study was to investigate the protective mechanism of mucoadhesive microspheres loaded with alkaloids from C. chinensis Franch. and E. rutaecarpa (Juss. Benth. on ethanol-induced acute gastric mucosal injury in rats. Surface morphology, particle size, drug loading, encapsulation efficiency, in vitro drug release, mucoadhesiveness, and fluorescent imaging of the microspheres in gastrointestinal tract were studied. The results showed that the mucoadhesive microspheres loaded with alkaloids could sustain the release of drugs beyond 12 hours and had gastric mucoadhesive property with 82.63% retention rate in vitro. The fluorescence tracer indicated high retention of mucoadhesive microspheres within 12 hours in vivo. The mucoadhesive microspheres loaded with alkaloids could reduce the gastric injury by decreasing the mucosal lesion index, increasing the percentage of inhibition and increasing the amount of mucus in the gastric mucosa in an ethanol-induced gastric mucosal injury rat model.

    Gastric pseudolymphoma is an uncommon benign lesion which poses a difficult problem in diagnosis and management. Lymphoid hyperplasia of the stomach, however, may occasionally precede true gastric lymphoma. Endoscopic, radiologic and pathological findings are not generally helpful in establishing the diagnosis preoperatively. Benign gastric lymphoid hyperplasia could be mistaken radiologically for ulcerated gastric carcinoma and pathologically for malignant lymphoma. Recognition of this condition is important to prevent unnecessary treatment by surgery or radiotherapy. About 140 case reports have been published to date. This paper describes the cases of two further patients. (orig.) [de

    Full Text Available Parkia platycephala Benth. (Leguminosae - Mimosoideae, popularly known as "visgueira", fava bean tree or "fava-de-bolota", is widely found in the Northern and Northeastern regions of Brazil. Its pods are used as cattle food supplement in the drought period. Compounds with a gastroprotective activity were obtained from the genus Parkia. Therefore, this study aimed at investigating the gastroprotective effect of the ethanolic extract of Parkia platycephala Benth. leaves (Pp-EtOH, as well as evaluating its possible mechanisms of action in experimental ulcer induction models. Lesions were induced by absolute ethanol, ethanol-HCl, ischemia-reperfusion and indomethacin in rodents. Pp-EtOH showed a protective effect in the lesion models (66, 48 and 52 %, respectively, but it was not able to protect gastric mucosa against indomethacin-induced lesions. Results show a possible participation of the NO-synthase pathway in the gastroprotection and an antioxidant activity, by the increase of the catalase activity. The participation of prostaglandins and potassium channels sensitive to ATP in the gastroprotective effect of Pp-EtOH seems less likely to occur. More comprehensive studies, therefore, should be carried out to elucidate the antiulcerative effects of this promising natural product against this gastrointestinal disorder.

    Gastric cancer is still a major health problem and a leading cause of cancer mortality despite a worldwide decline in incidence. Primarily due to early detection of the disease, the results of treatment for gastric cancer have improved in Japan, Korea and several specialized Western centres. Surgery offers excellent long-term survival results for early gastric cancer (EGC). In the Western world, however more than 80 % of patients at diagnosis have an advanced gastric cancer with a poor prognosis. The aim of surgery is the complete removal of the tumour (UICC R0-resection), which is known to be the only proven, effective treatment modality and the most important treatmentrelated prognostic factor. The prognosis after surgical treatment of gastric cancer remains poor. Neoadjuvant chemotherapy is a rising option in locally advanced gastric cancer. Adjuvant chemoradiation has been shown to be beneficial in gastric cancer patients who have undergone suboptimal surgical resection. The benefits of adjuvant chemotherapy alone seem to be very small, Untreated metastatic gastric cancer is associated with a median survival of only 3 - 4 months, but this can be increased to 8 - 10 months, associated with improved quality of life, with combination chemotherapy. Currently, no standard combination chemotherapy regimen exists, although regimens utilizing both cisplatin and 5-fluorouracil, such as epirubicin/cisplatin/fluorouracil (ECF) or docetaxel/cisplatin/fluorouracil (DCF) are amongst the most active. Newer chemotherapeutic agents, including irinotecan, oxaliplatin and taxanes, show promising activity, and are currently being tested with biologics in clinical trials. (author)

    Mucosal pH (pHi) is influenced by local perfusion and metabolism (mucosal-arterial pCO2 gradient, DeltapCO2), systemic metabolic acidosis (arterial bicarbonate), and respiration (arterial pCO2). We determined these components of pHi and their relation to outcome during the first 24 h of intensive care. We studied 103 patients with acute respiratory or circulatory failure (age, 63+/-2 [mean+/-SEM]; Acute Physiology and Chronic Health Evaluation II score, 20+/-1; Sequential Organ Failure Assessment score, 8+/-0). pHi, and the effects of bicarbonate and arterial and mucosal pCO2 on pHi, were assessed at admission, 6, and 24 h. pHi was reduced (at admission, 7.27+/-0.01) due to low arterial bicarbonate and increased DeltapCO2. Low pHi (or=7.32 at admission; P=0.061) was associated with an increased DeltapCO2 in 59% of patients (mortality, 47% vs. 4% for patients with low pHi and normal DeltapCO2; P=0.0003). An increased versus normal DeltapCO2, regardless of pHi, was associated with increased mortality at admission (51% vs. 5%; Pacidosis. Inadequate tissue perfusion may persist despite stable hemodynamics and contributes to poor outcome.

    Full Text Available The objective of this study was to explore the gastroprotective properties of the aerial part of Lycium chinense Mill (LCA against ethanol-induced gastric mucosa lesions in mice models. Administration of LCA at doses of 50, 100, 200 and 400 mg/kg body weight prior to ethanol consumption dose dependently inhibited gastric ulcers. The gastric mucosal injury was analyzed by gastric juice acidity, glutathione (GSH, superoxide dismutase (SOD, malondialdehyde (MDA, myeloperoxidase (MPO activities. Furthermore, the levels of the inflammatory mediators, tumor necrosis factor-α (TNF-α, interleukin-6 (IL-6 and interleukin-1β (IL-1β in serum were also analyzed using ELISA. Pathological changes were also observed with the aid of hematoxylin-eosin (HE staining. Our results indicated that LCA significantly reduced the levels of MPO, MDA and increased SOD and GSH activities. Furthermore, LCA also significantly inhibited the levels of TNF-α, IL-6, and IL-1β in the serum of ulcerated mice in a dose dependent manner. Immunohistological analysis indicated that LCA also significantly attenuated the overexpression of nuclear factor-κB in pretreated mice models. This findings suggests Lycium chinense Mill possesses gastroprotective properties against ethanol-induced gastric injury and could be a possible therapeutic intervention in the treatment and management of gastric ulcers.

    Gastric emptying (GE) of nutriments is a major function of the stomach. GE disorders are observed after gastric surgery and with various diseases, either of a strictly gastroenterologic kind or interesting other specialities (especially diabetes mellitus). Scintigraphy, which has allowed a better knowledge of GE physiological and pathological mechanisms, has now become the reference method for studying the emptying of solids and liquids. In a near future, it could well have two major applications: a diagnostic approach of functional digestive disorders and an assessment of the various effects of pharmacological drugs with digestive affinity [fr

  20. Gastric lactobezoar - a rare disorder?

    2012-01-01

    Full Text Available Abstract Gastric lactobezoar, a pathological conglomeration of milk and mucus in the stomach of milk-fed infants often causing gastric outlet obstruction, is a rarely reported disorder (96 cases since its first description in 1959. While most patients were described 1975-1985 only 26 children have been published since 1986. Clinically, gastric lactobezoars frequently manifest as acute abdomen with abdominal distension (61.0% of 96 patients, vomiting (54.2%, diarrhea (21.9%, and/or a palpable abdominal mass (19.8%. Respiratory (23.0% and cardiocirculatory (16.7% symptoms are not uncommon. The pathogenesis of lactobezoar formation is multifactorial: exogenous influences such as high casein content (54.2%, medium chain triglycerides (54.2% or enhanced caloric density (65.6% of infant milk as well as endogenous factors including immature gastrointestinal functions (66.0%, dehydration (27.5% and many other mechanisms have been suggested. Diagnosis is easy if the potential presence of a gastric lactobezoar is thought of, and is based on a history of inappropriate milk feeding, signs of acute abdomen and characteristic features of diagnostic imaging. Previously, plain and/or air-, clear fluid- or opaque contrast medium radiography techniques were used to demonstrate a mass free-floating in the lumen of the stomach. This feature differentiates a gastric lactobezoar from intussusception or an abdominal neoplasm. Currently, abdominal ultrasound, showing highly echogenic intrabezoaric air trapping, is the diagnostic method of choice. However, identifying a gastric lactobezoar requires an investigator experienced in gastrointestinal problems of infancy as can be appreciated from the results of our review which show that in not even a single patient gastric lactobezoar was initially considered as a possible differential diagnosis. Furthermore, in over 30% of plain radiographs reported, diagnosis was initially missed although a lactobezoar was clearly

    Full Text Available A bezoar is an intraluminal mass formed by the accumulation of undigested material in the gastrointestinal tract. Trichobezoar is a rare condition seen almost exclusively in young women with trichotillomania and trichotillophagia. When not recognized, the trichobezoar continues to grow, which increases the risk of severe complications such as gastric ulceration and even perforation. Formation of a gallstone within the trichobezoar (tricholithobezoar is an event that has not yet been described. We report the case of a 22-year-old woman admitted to the emergency room with signals and symptoms of an epigastric mass and perforative acute abdomen. Radiological study revealed bilateral pneumoperitoneum. Personal history revealed depressive syndrome, trichotillomania and trichophagia. With a diagnosis of visceral perforation, an urgent exploratory laparotomy was performed. This confirmed the diagnosis of gastric perforation due to a large trichobezoar with the formation of a gastrolith that was removed by anterior gastrotomy. Biochemical study of the gastric stone revealed that it was composed of bile salts. There were no complications. The patient was discharged on the 5th postoperative day and was referred for psychiatric treatment.

  2. Lethal mechanisms in gastric volvulus.

    A 55-year-old wheelchair-bound woman with severe cerebral palsy was found at autopsy to have marked distention of the stomach due to a volvulus. The stomach was viable, and filled with air and fluid and had pushed the left dome of the diaphragm upwards causing marked compression of the left lung with a mediastinal shift to the right (including the heart). There was no evidence of gastric perforation, ischaemic necrosis or peritonitis. Removal of the organ block revealed marked kyphoscoliosis. Histology confirmed the viability of the stomach and biochemistry showed no dehydration. Death in cases of acute gastric volvulus usually occurs because of compromise of the gastric blood supply resulting in ischaemic necrosis with distention from swallowed air and fluid resulting in perforation with lethal peritonitis. Hypovolaemic shock may also occur. However, the current case demonstrates an alternative lethal mechanism, that of respiratory compromise due to marked thoracic organ compression.

    70 cases of gastric mucosal erosions were diagnosed by double contrast upper gastrointestinal examinations and endoscopic findings. Analyzing the radiologic findings of these 70 cases of gastric mucosal erosions, the following results were obtained. 1. Among the total 70 cases, 65 cases were typical varioliform erosions showing central depressions and surrounding mucosal elevations. Remaining 5 cases were erosions of acute phase having multiple irregular depressions without surrounding elevations. 2. The gastric antrum was involved alone or in part in all cases. Duodenal bulb was involved with gastric antrum in 4 cases. 3. The majority of the cases had multiple erosions. There were only 2 cases of single erosion. 4. In 65 cases of varioliform erosions; 1) The diameter of the surrounding elevations varied from 3 to 20 mm with the majority (47 cases) between 6 and 10 mm. 2) In general, the surrounding elevations with sharp margin on double contrast films were also clearly demonstrated on compression films but those with faint margin were not. 3) The size of the central barium collections varied from pinpoint to 10 mm with the majority under 5 mm. The shape of the central barium collections in majority of the cases were round with a few cases of linear, triangular or star-shape. 5. In 5 cases of acute phase erosions; 1) All the 5 cases were females. 2) On double contrast radiography, all the cases showed multiple irregular depressed lesions without surrounding elevations. 3) 1 case had the history of hematemesis. 4) In 1 case, there was marked radiological improvement on follow-up study of 2 months interval. 6. In 23 cases, there were coexistent diseases with gastric mucosal erosions. These were 13 cases of duodenal bulb ulcers,7 cases of benign gastric ulcers and 3 others

    Suresh Kumar Nayudu

    2013-01-01

    Full Text Available Hyperplastic gastric polyps are incidentally diagnosed during upper gastrointestinal endoscopy. They are known to cause gastric outlet obstruction and chronic blood loss leading to iron deficiency anemia. However, hyperplastic gastric polyp presenting as acute severe upper gastrointestinal bleeding is very rare. To the best of our knowledge, there have been two cases of hyperplastic gastric polyps presenting as acute gastrointestinal bleeding in the medical literature. We present a case of a 56-year-old African American woman who was admitted to our hospital with symptomatic anemia and sepsis. The patient developed acute upper gastrointestinal bleeding during her hospital stay. She underwent emergent endoscopy, but bleeding could not be controlled. She underwent emergent laparotomy and wedge resection to control the bleeding. Biopsy of surgical specimen was reported as hyperplastic gastric polyp. We recommend that physicians should be aware of this rare serious complication of hyperplastic gastric polyps as endoscopic polypectomy has diagnostic and therapeutic benefits in preventing future complications including bleeding.

    Full Text Available History of present illness: A 12-year-old female with no past medical history presented with abdominal pain for 3 months. The pain was intermittent, located at the epigastric region, non-radiating, fluctuating intensity up to 8/10, and had worsened over the past month. She did not have fever, nausea, vomiting, diarrhea, constipation, or blood in her stool. The patient also endorsed hair loss over the same time period and noted that her previously long hair was now short and thin. On exam, patient was noted to have shoulder-length hair, a soft, non-distended abdomen with mild tenderness to the epigastric region, and a 5cm hard mass palpated at the epigastrium. Significant findings: In the abdominal radiograph, a nonspecific and non-obstructive bowel gas pattern with no air-fluid level was noted, however the stomach was distended with soft tissue. The CT abdomen/pelvis revealed a distended stomach with undigested heterogeneous contents (presumed bezoar. Discussion: A bezoar is a mass of incompletely digested material typically originating in the stomach and consisting of vegetable fibers, hair, or drugs.1 Bezoars develop after ingested foreign material accumulates in the gastrointestinal tract due to indigestibility, gastric outlet obstruction, or intestinal stasis. Trichobezoars are comprised of hair and classically form in young females with an underlying psychiatric disorder resulting in the urge to pull one’s hair out (trichotillomania and swallow it (trichophagia.2,3 Gastric bezoars are rare with an approximate incidence of 0.3 percent of patients undergoing upper endoscopy.4 Patients tend to remain asymptomatic for long periods, but may develop abdominal pain, nausea/vomiting, early satiety, anorexia, and weight loss.5 Complications may include gastrointestinal ulcerations, perforations, intussusception, pancreatitis, obstructive jaundice, and death.6-8 The diagnosis of a gastric bezoar can be made using plain films, ultrasound, or CT, and

    Full Text Available Background. Although relatively rare, gastric vascular anomalies can be recognized as a source of both chronic and acute blood loss, most often presenting as long term iron deficiency anemia, rarely as severe acute gastrointestinal bleeding. Case report. We present five patients with various gastric vascular anomalies, diagnosed during the year of 2003. in the Clinical Hospital Center Zemun. The diagnosis was based on endoscopic appearances, clinical history and characteristic histological findings. Gastric vascular anomalies presented in our review were: portal hypertensive gastropathy, gastric antral vascular ectasia, angiodysplasia, hereditary hemorrhagic telangiectasia and Dieulafoy lesion. The used treatment modalities included surgery and various endoscopic techniques (schlerotherapy, argon plasma coagulation. Conclusion. Patients presented with chronic iron deficiency anemia or acute and recurrent gastrointestinal hemorrhage should be considered as having one of gastric vascular anomalies.

Swiss male mice were treated with vehicle, LYSO-7 or Bezafibrate (p.o. 1 hour before oral administration of Et/HCl (60%/0.03M. In another set of assays, animals were injected i.p. with an anti-granulocyte antibody, GW9962 or L-NG-nitroarginine methyl ester (L-NAME before treatment. One hour after Et/HCl administration, neutrophils were quantified in the blood and bone marrow and the gastric microcirculatory network was studied in situ. The gastric tissue was used to quantify the percentage of damaged area, as well as myeloperoxidase (MPO, inducible nitric oxide synthase (iNOS, endothelial nitric oxide synthase (eNOS protein and PPARγ protein and gene expression. Acid secretion was evaluated by the pylorus ligation model. LYSO-7 or Bezafibrate treatment reduced the necrotic area. LYSO-7 treatment enhanced PPARγ gene and protein expression in the stomach, and impaired local neutrophil influx and stasis of the microcirculatory network caused by Et/HCl administration. The effect seemed to be due to PPARγ agonist activity, as the LYSO-7 effect was abolished in GW9962 pre-treated mice. The reversal of microcirculatory stasis, but not neutrophil influx, was mediated by nitric oxide (NO, as L-NAME pre-treatment abolished the LYSO-7-mediated reestablishment of microcirculatory blood flow. This effect may depend on enhanced eNOS protein expression in injured gastric tissue. The pH and concentration of H(+ in the stomach were not modified by LYSO-7 treatment. In addition, LYSO-7 may induce less toxicity, as 28 days of oral treatment did not induce weight loss, as detected in pioglitazone treated mice. Thus, we show that LYSO-7 may be an effective treatment for gastric lesions by controlling

    Full Text Available Perforation is a rare complication of gastric carcinoma, and it occurs in less than 5% of all gastric carcinoma cases and in less than 1% within all acute abdomen cases. The diagnosis of malignancy is usually not validated preoperatively. In previous reported English literature, all patients with perforated gastric cancer have the feature of old age. This feature might be able to guide the surgeon to impress the differential diagnosis of malignancy before or during the emergent operation of gastric perforation.This 32-year-old male patient suffered from sudden onset of epigastric pain. We performed emergent operation under the impression of hollow organ perforation. The postoperative pathologic report of gastric ulcer revealed gastric carcinoma. We performed second-stage operation of total gastrectomy with D2 lymphadenectomy smoothly 7 days later. As we know, this is the youngest patient having the condition of perforated gastric carcinoma reported in the literature. This case reminds us that it is possible for perforated gastric carcinoma to occur in young-age patients. Keywords: Gastric cancer, Acute abdomen, Gastric perforation

    2018-01-01

    Alterations in the immune response of patients with autoimmune diseases may predispose to malignancies, and a link between chronic autoimmune gastritis and gastric cancer has been reported in many studies. Intestinal metaplasia with dysplasia of the gastric corpus-fundus mucosa and hyperplasia of chromaffin cells, which are typical features of late-stage autoimmune gastritis, are considered precursor lesions. Autoimmune gastritis has been associated with the development of two types of gastric neoplasms: intestinal type and type I gastric carcinoid. Here, we review the association of autoimmune gastritis with gastric cancer and other autoimmune features present in gastric neoplasms. PMID:29373557

    Chronic inflammation is related with cancer and leads to worsening prognosis in cancer patients. n-3 polyunsaturated fatty acids (PUFAs) supplementation has been proposed as adjuvant treatment in cancer due anti-inflammatory properties. In the present meta-analysis, we pooled randomized clinical trials (RCTs) assessing the effects of n-3 PUFAs (from fish oil isolated or added in an immunonutrition formula) on inflammatory markers in gastric cancer. A comprehensive literature search was performed in Medline, Scopus, Cochrane library, Science Direct and Web of Science, besides GOOGLE Scholar and a hand searching of reference lists, through July 2016. We pooled the effect size from individual studies using a random-effect model and carried out heterogeneity and sensitivity analyses. Nine trials (698 patients) fulfilled the entry criteria and were included in the synthesis of the systematic review. Eight were carried out in surgical patients and one in patients that received chemotherapy. Four used only fish oil as intervention and five used an immunonutrition formula. Global meta-analysis demonstrated higher albumin (7 studies, SMD 0.28; 95% CI 0.07, 0.48) and prealbumin (4 studies, SMD 0.56; 95% CI 0.12, 1.00) concentrations, and lower IL-6 (2 studies, SMD -0.71; 95% CI -1.15, -0.27) and TNF-α (2 studies, SMD -0.92; 95% CI -1.58, -0.26) concentrations in patients of the intervention group as compared to control group. However, total protein, transferrin and CRP concentrations were not improved by n-3 PUFAs supplementation. This study provides evidence that n-3 PUFAs supplementation from fish oil or added an immunonutrition formula has favorable effects on inflammatory markers in gastric cancer patients undergoing surgical procedures.

    2003-09-01

    Gastric surgery is commonly performed to remove foreign bodies and correct gastric dilatation-volvulus and is less commonly performed to treat gastric ulceration or erosion, neoplasia, and benign gastric outflow obstruction. Intestinal surgery, although commonly performed by veterinarians, should never be considered routine. The most common procedures of the small intestinal tract performed in dogs and cats include enterotomy and resection/anastomosis. Surgery of the large intestine is indicated for lesions causing obstruction, perforations, colonic inertia, or chronic inflammation.

    The roentgenographic recognition of gastric varices often is difficult, even when there is a history of liver disease or splenomegaly without demonstrable esophageal varices. An apparant polypoid filling defect with exaggerated mucosal folds in proximal portion of the gastric body and funds on upper GI series, accompanied by hematemesis and splenomegly should suggest the presence of pseudotumoral gastric varices. We have an experience a case of polypoid filling defects in gastric fundus of psudotumoral gastric varices of 49 years old Korean woman, which was diagnosed by surgical and histopathological findings

    A natural source of medicine, Enicosanthellum pulchrum is a tropical plant which belongs to the family Annonaceae. In this study, methanol extract from the leaves and stems of this species was evaluated for its gastroprotective potential against mucosal lesions induced by ethanol in rats. Seven groups of rats were assigned, groups 1 and 2 were given Tween 20 (10% v/v) orally. Group 3 was administered omeprazole 20 mg/kg (10% Tween 20) whilst the remaining groups received the leaf and stem extracts at doses of 150 and 300 mg/kg, respectively. After an additional hour, the rats in groups 2-7 received ethanol (95% v/v; 8 mL/kg) orally while group 1 received Tween 20 (10% v/v) instead. Rats were sacrificed after 1 h and their stomachs subjected to further studies. Macroscopically and histologically, group 2 rats showed extremely severe disruption of the gastric mucosa compared to rats pre-treated with the E. pulchrum extracts based on the ulcer index, where remarkable protection was noticed. Meanwhile, a significant percentage of inhibition was shown with the stem extract at 62% (150 mg/kg) and 65% (300 mg/kg), whilst the percentage with the leaf extract at doses of 150 and 300 mg/kg was 63% and 75%, respectively. An increase in mucus content, nitric oxide, glutathione, prostaglandin E2, superoxide dismutase, protein and catalase, and a decrease in malondialdehyde level compared to group 2 were also obtained. Furthermore, immunohistochemical staining of groups 4-7 exhibited down-regulation of Bax and up-regulation of Hsp70 proteins. The methanol extract from the leaves and the stems showed notable gastroprotective potential against ethanol.

    Full Text Available We evaluated the effects of fundectomy and pyloroplasty on the delay of gastric emptying (GE and gastrointestinal (GI transit of liquid due to blood volume (BV expansion in awake rats. Male Wistar rats (N = 76, 180-250 g were first submitted to fundectomy (N = 26, Heinecke-Mikulicz pyloroplasty (N = 25 or SHAM laparotomy (N = 25. After 6 days, the left external jugular vein was cannulated and the animals were fasted for 24 h with water ad libitum. The test meal was administered intragastrically (1.5 ml of a phenol red solution, 0.5 mg/ml in 5% glucose to normovolemic control animals and to animals submitted to BV expansion (Ringer-bicarbonate, iv infusion, 1 ml/min, volume up to 5% body weight. BV expansion decreased GE and GI transit rates in SHAM laparotomized animals by 52 and 35.9% (P<0.05. Fundectomy increased GE and GI transit rates by 61.1 and 67.7% (P<0.05 and prevented the effect of expansion on GE but not on GI transit (13.9% reduction, P<0.05. Pyloroplasty also increased GE and GI transit rates by 33.9 and 44.8% (P<0.05 but did not prevent the effect of expansion on GE or GI transit (50.7 and 21.1% reduction, P<0.05. Subdiaphragmatic vagotomy blocked the effect of expansion on GE and GI transit in both SHAM laparotomized animals and animals submitted to pyloroplasty. In conclusion 1 the proximal stomach is involved in the GE delay due to BV expansion but is not essential for the establishment of a delay in GI transit, which suggests the activation of intestinal resistances, 2 pyloric modulation was not apparent, and 3 vagal pathways are involved

    Chronic gastric volvulus in dogs results in long-standing gastrointestinal signs unlike those of acute gastric dilatation and volvulus. This report describes chronic gastric volvulus in seven dogs. The majority of dogs presented with weight loss, chronic vomiting, lethargy and abdominal pain. A combination of radiographic, ultrasonographic and endoscopic imaging indicated altered positioning of gastric landmarks. Dynamic changes were identified in some cases. Exploratory coeliotomy and surgical gastropexy were performed in all dogs. Clinical signs improved or resolved in six of seven dogs postoperatively. Chronic gastric volvulus is an uncommon condition in dogs, but should be considered as a differential in cases presenting with the above clinical signs. © 2011 British Small Animal Veterinary Association.

    The estimated volume of meal in the stomach 30 mins after sup(113m)In-DTPA administration was determined in patients with gastric ulcer and normal controls by 1) relating counts in the stomach to those in the whole field of view of the gamma camera and 2) aspirations. In the normal controls there was no significant difference between the two methods but in the gastric ulcer patients, the gamma camera method predicted significantly more meal in the stomach than was recovered by aspiration. It was suggested that the large low lying stomach found in gastric ulcer disease causes extensive overlap of the small bowel and invalidates measurements of gastric emptying made by a gamma camera.

    Surgery is an increasingly important management option for patients with obesity. Laparoscopic adjustable gastric banding is a procedure employed to treat morbid obesity refractory to medical therapy. It works by reducing the capacity of the stomach and promoting early satiety. We report the unusual case of a 33-year-old female who presented acutely 2 years following laparoscopic adjustable gastric banding with cecal volvulus and closed loop obstruction caused by displacement of the connecting tube.

    Gastric volvulus is a rare entity defined as an abnormal rotation of the stomach around itself. It is a diagnosis of exclusion; the clinical index of suspicion is always low and is mostly diagnosed on imaging or on the surgery table. When it occurs, it is an emergency due to the risk of strangulation and consequent gangrene of the stomach. Mesentero-axial (MA) gastric volvuli constitute one-third of all cases. Here, we are present an interesting case of acute MA gastric volvulus diagnosed with imaging and treated subsequently. PMID:29755908

    Full Text Available First described by Berti in 1866, gastric volvulus (GV is an uncommon and potentially lethal entity. GV occurs when the stomach twists by more than 180º resulting in obstruction of the alimentary tract, visceral ischemia, necrosis, and perforation. It is classified according to the rotation axis in organoaxial, mesenteroaxial or a combination of both. The clinical presentation can be acute, and is usually severe or chronic, which sometimes may be asymptomatic. It predominantly occurs in the fifth decade of life, but children, mainly those under the age of 1 year, may be affected. No ethnicity or gender was observed to show predominance. This entity is related to gastric, diaphragmatic disorders as well as laxity of gastric ligaments. Acute GV may complicate with incarceration and strangulation of the stomach when gastric necrosis ensues. These cases show a mortality rate of 60%. The authors report the fatal case of a surgically treated GV in a 43-year-old female patient who looked for medical care only after 1 month of initial symptoms. Diagnosis was confirmed with a thoracic and abdominal axial computed tomography. Besides the entire stomach being herniated and twisted into the thoracic cavity, the pancreas was pulled up through the hiatal orifice, provoking acute pancreatitis. Because of gastric necrosis and perforation, gastroenteric fluid drained into the mediastinum and left pleural space. The postoperative outcome was unfavorable resulting in the patient’s death. The authors call attention to the severeness of the disease, and therefore the need of precocity of diagnosis and surgical treatment.

    Gastric non-Hodgkin lymphoma is a rare tumour that represents approximately 7% of all stomach cancers and 2% of all lymphomas. The most frequent location of gastric MALT (mucosa associated lymphoid tissue) lymphomas is in the antrum in 41% of the cases, and 33% can be multifocal. The risk of spontaneous perforation of a gastric MALT lymphoma is 4-10%. 24 year old male patient carrying the Human Immunodeficiency Virus, who began with signs and symptoms of acute abdomen and fever 72 hours before arriving in the emergency room. A computed tomography was performed that showed free fluid in the cavity, and gastric wall thickening. The patient underwent a laparotomy, finding absence of the anterior wall of the stomach, sealed with the left lobe of the liver, colon and omentum. Total gastrectomy, with oesophagosty and jejunostomy tube, was performed. Gastric perforation secondary to a MALT lymphoma is rare, with high mortality. There is limited information reported of this complication and should be highly suspected in order to provide appropriate treatment for a complication of this type.

    Although the majority of gastric carcinomas are sporadic, approximately 10% show familial aggregation, and a hereditary cause is determined in 1%-3% cases. Of these, hereditary diffuse gastric cancer is the most recognized predisposition syndrome. Although rare, the less commonly known syndromes also confer a markedly increased risk for development of gastric cancer. Identification and characterization of these syndromes require a multidisciplinary effort involving oncologists, surgeons, genetic counselors, biologists, and pathologists. This article reviews the molecular genetics, clinical and pathologic features, surveillance guidelines, and preventive measures of common and less common hereditary gastric cancer predisposition syndromes. ©AlphaMed Press.

    The gastric lesion is a common source of complaints to Orientals, however, evaluation of gastric symptoms and laboratory examination offer little specific aid in the diagnosis of gastric diseases. Thus roentgenography of gastrointestinal tract is one of the most reliable method for detail diagnosis. On double contract study of stomach, gastric filling defect is mostly caused by malignant gastric cancer, however, other benign lesions can cause similar pictures which can be successfully treated by surgery. 66 cases of benign causes of gastric filling defect were analyzed at this point of view, which was verified pathologically by endoscope or surgery during recent 7 years in Yensei University College of Medicine, Severance Hospital. The characteristic radiological picture of each disease was discussed for precise radiologic diagnosis. 1. Of total 66 cases, there were 52 cases of benign gastric tumor 10 cases of gastric varices, 5 cases of gastric bezoar, 5 cases of corrosive gastritis, 3 cases of granulomatous disease and one case of gastric hematoma. 2. The most frequent causes of benign tumors were adenomatous polyp (35/42) and the next was leiomyoma (4/42). Others were one of case of carcinoid, neurofibroma and cyst. 3. Characteristic of benign adenomatous polyp were relatively small in size, smooth surface and were observed that large size, benign polyp was frequently type IV lesion with a stalk. 4. Submucosal tumors such as leiomyoma needed differential diagnosis with polypoid malignant cancer. However, the characteristic points of differentiation was well circumscribed smooth margined filling defect without definite mucosal destruction on surface. 5. Gastric varices showed multiple lobulated filling defected especially on gastric fundus that changed its size and shape by respiration and posture of patients. Same varices lesions on esophagus and history of liver disease were helpful for easier diagnosis. 6. Gastric bezoar showed well defined movable mass

    Weight loss following gastroplasty had no correlation with gastric emptying rate. Patients who showed transient prolongation of gastric emptying returned to normal one year later and showed no significant difference in weight loss from those who did not have temporary delayed gastric emptying. Perhaps gatroplasty (at least temporarily) reduces the gastric volume producing early satiation without affecting the gastric emptying rate as tested by a small volume radiolabelled test meal. Longer follow-up is indicated to see if delayed weight gain occurs because of gastric pouch stretching and if this has any correlation with gastric emptying rate. (Author)

    1988-01-01

    This study was designed to test the hypothesis that thyroid states may affect the acute development of gastric lesions induced by cold-resistant stress. Normal (euthyroid), hyperthyroid and hypothyroid rats were used. Gastric lesion incidence and severity was significantly increased in hypothyroid rats, whereas in contrast hyperthyroid rats developed significantly less gastric lesions. As anticipated, plasma levels of thyroxin (T/sub 4/) were significantly elevated in hyperthyroid rats, and undetectable in hypothyroid rats. Acute pretreatment with i.p. cimetidine, but not T/sub 4/ 1 h prior to stress completely prevented gastric lesions formation in hypothyroid rats. Finally, binding of /sup 3/H-dihydroalprenolol to ..beta..-adrenergic receptors on brain membranes prepared from frontal cortex was reduced by 20% in hypothyroid rats after 3 h of stress. These and other data contained herein suggest that thyroid hormones contribute to modulate the responsiveness of the gastric mucosa to stress. The increase rate of ulcerogenesis observed in hypothyroid rats appears to be mediated by gastric acid secretion. The central mechanism for this response may involve decreased brain nonadrenergic receptor function.

    Mechanisms regulating gastric emptying have been characterized through many decades of experimental work. Both central and peripheral mechanisms are important. Central mechanisms are related to the center of vomiting and are probably influenced by psychologic and emotional factors. Peripheral mechanisms are located at both sides of the pylorus. Gastric mechanisms are stimulatory and are triggered mainly by distention of the stomach, although hormonal mechanisms may also participate (gastrin). However, with complex, nutrient-containing meals, the intragastric volume is not the primary determinant of gastric emptying. Inhibitory mechanisms of the gut are more important. The key factors are the pH, osmolality, and nutrient content of the chyme being emptied into the duodenum. Osmotic and pH-sensitive receptors are thought to reside in the duodenum. On the other hand, receptors triggered by nutrients extend much more distally into the duodenum and are sensitive to nutrient composition and load. Protein, carbohydrates, and lipids all inhibit gastric emptying, although the lipids are probably the most potent inhibitors. If the duodenal load or the characteristics of the emptying material are not adequate, inhibitory mechanisms will reduce gastric emptying at the expense of expanding the intragastric volume. It is therefore not possible to dissociate postprandial gastric emptying from postprandial gastric secretion

    Gastric polyps are usually found incidentally during upper gastrointestinal endoscopic examinations. These polyps are generally benign, with hyperplasia being the most common. While gastric polyps are often asymptomatic, they can cause gastric outlet obstruction. A 64 years-old female patient presented to our polyclinic with a history of approximately 2 months of weakness, occasional early nausea, vomiting after meals and epigastric pain. A polypoid lesion of approximately 25mm in diameter was detected in the antral area of the stomach, which prolapsed through the pylorus into the duodenal bulbus, and subsequently caused gastric outlet obstruction, as revealed by upper gastrointestinal endoscopy of the patient. The polyp was retrieved from the pyloric canal into the stomach with the aid of a tripod, and snare polypectomy was performed. Currently, widespread use of endoscopy has led to an increase in the frequency of detecting hyperplastic polyps. While most gastric polyps are asymptomatic, they can cause iron deficiency anemia, acute pancreatitis and more commonly, gastric outlet obstruction because of their antral location. Although there are no precise principles in the treatment of asymptomatic polyps, polyps >5mm should be removed due to the possibility of malignant transformation. According to the medical evidence, polypectomy is required for gastric hyperplastic polyps because of the risks of complication and malignancy. These cases can be successfully treated endoscopically.

    2011-03-01

    Full Text Available Introduction: The association of acute viral hepatitis and acute pancreatitis is well described. This study was conducted to find out the frequency of pancreatic involvement in acute viral hepatitis in the Nepalese population. Methods: Consecutive patients of acute viral hepatitis presenting with severe abdominal pain between January 2005 and April 2010 were studied. Patients with history of significant alcohol consumption and gall stones were excluded. Acute viral hepatitis was diagnosed by clinical examination, liver function test, ultrasound examination and confirmed by viral serology. Pancreatitis was diagnosed by clinical presentation, biochemistry, ultrasound examination and CT scan. Results: Severe abdominal pain was present in 38 of 382 serologically-confirmed acute viral hepatitis patients. Twenty five patients were diagnosed to have acute pancreatitis. The pancreatitis was mild in 14 and severe in 11 patients. The etiology of pancreatitis was hepatitis E virus in 18 and hepatitis A virus in 7 patients. Two patients died of complications secondary to shock. The remaining patients recovered from both pancreatitis and hepatitis on conservative treatment. Conclusions: Acute pancreatitis occurred in 6.5 % of patients with acute viral hepatitis. Cholelithiasis and gastric ulcers are the other causes of severe abdominal pain. The majority of the patients recover with conservative management. Keywords: acute viral hepatitis, acute pancreatitis, pain abdomen, hepatitis E, hepatitis A, endemic zone

    Individuals infected with Helicobacter pylori, a stomach colonizing bacteria, have an increased risk of developing gastric malignancies. The risk for developing cancer relates to the physiologic and histologic changes that H. pylori infection induces in the stomach. In the last year numerous studies have been conducted in order to characterize the association between H. pylori infection and gastric cancer. These studies range from epidemiologic approaches aiming at the identification of envir...

  4. Gastric Adenocarcinoma Presenting with Gastric Outlet Obstruction in a Child

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Gastric carcinoma is extremely rare in children representing only 0.05% of all gastrointestinal malignancies. Here, we report the first pediatric case of gastric cancer presenting with gastric outlet obstruction. Upper endoscopy revealed a markedly thickened antral mucosa occluding the pylorus and a clean base ulcer 1.5 cm × 2 cm at the lesser curvature of the stomach. The narrowed antrum and pylorus underwent balloon dilation, and biopsy from the antrum showed evidence of Helicobacter pylori gastritis. The biopsy taken from the edge of the gastric ulcer demonstrated signet-ring-cell type infiltrate consistent with gastric adenocarcinoma. At laparotomy, there were metastases to the liver, head of pancreas, and mesenteric lymph nodes. Therefore, the gastric carcinoma was deemed unresectable. The patient died few months after initiation of chemotherapy due to advanced malignancy. In conclusion, this case report underscores the possibility of gastric adenocarcinoma occurring in children and presenting with gastric outlet obstruction.

    The problem is that current definitions of early gastric cancer allow the inclusion of regional lymph node metastases. The increasing use of endoscopic submucosal dissection to treat early gastric cancer is a concern because regional lymph nodes are not addressed. The aim of the study was thus to critically evaluate current evidence with regard to tumour-specific factors associated with lymph node metastases in "early gastric cancer" to develop a more precise definition and improve clinical management. A systematic and comprehensive search of major reference databases (MEDLINE, EMBASE, PubMed and the Cochrane Library) was undertaken using a combination of text words "early gastric cancer", "lymph node metastasis", "factors", "endoscopy", "surgery", "lymphadenectomy" "mucosa", "submucosa", "lymphovascular invasion", "differentiated", "undifferentiated" and "ulcer". All available publications that described tumour-related factors associated with lymph node metastases in early gastric cancer were included. The initial search yielded 1494 studies, of which 42 studies were included in the final analysis. Over time, the definition of early gastric cancer has broadened and the indications for endoscopic treatment have widened. The mean frequency of lymph node metastases increased on the basis of depth of infiltration (mucosa 6% vs. submucosa 28%), presence of lymphovascular invasion (absence 9% vs. presence 53%), tumour differentiation (differentiated 13% vs. undifferentiated 34%) and macroscopic type (elevated 13% vs. flat 26%) and tumour diameter (≤2 cm 8% vs. >2 cm 25%). There is a need to re-examine the diagnosis and staging of early gastric cancer to ensure that patients with one or more identifiable risk factor for lymph node metastases are not denied appropriate chemotherapy and surgical resection.

    Acute gastric volvulus is a rare, but potentially life-threatening, cause of upper gastrointestinal obstruction. Male of 60 years old with severe epigastric pain and abdominal distension with haematemesis on two occasions. The patient was haemodynamically stable, with abdominal distension and palpable epigastric fullness. Hematic cytology showed: haemoglobin 8.2g/dl and haematocrit 27%. Abdominal X-ray showed an elevation of left diaphragm with a hugely dilated stomach. A nasogastric tube was inserted. Endoscopy was performed. There was no active bleeding, but it was impossible to reach the duodenum due to the stomach distortion. The upper gastrointestinal X-ray study showed the appearance of an inverted stomach in the chest and an organoaxial gastric torsion. The CT scans of thorax and abdomen showed a gastric ascent into the thoracic cavity. Laparoscopic surgery was performed, finding the left hemi-diaphragm elevated, and the stomach, splenic angle of the colon, the spleen and tail of the pancreas were also raised. A linear gastrectomy (gastric sleeve) was performed. The postoperative progress was satisfactory. Oral feeding was started 72 hours after surgery, and the patient was discharged, and has remained asymptomatic during the following by 8 years. Emergency physicians must maintain a high level of suspicion in patients that present with signs and symptoms suggesting upper digestive tract occlusion. The gastric sleeve is an excellent alternative to avoid recurrence of gastric volvulus. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A. All rights reserved.

    Intrathoracic gastric volvulus is a very rare surgical emergency. Early diagnosis and treatment are of great importance to prevent gastric gangrene and perforation or gastric obstruction and dilation, which may lead to cardiorespiratory arrest. We report two infants who presented with intrathoracic gastric volvulus. This was associated with recurrent diaphragmatic hernia in one and congenital paraoesophageal hernia in the other. Aspects of diagnosis and treatment are also discussed. (orig.)

    1999-03-01

    Peptic ulcer in the excluded segment of a gastric bypass performed in the management of morbid obesity has only rarely been reported in the literature. The purpose of this study is to review our experience with the condition in a series of 4300 patients who underwent gastric-restrictive surgery between 1978 and 1997. Eleven patients presented with acute perforation of a peptic ulcer in the excluded gastric segment. Nine ulcers were duodenal, one was gastric, and one patient had both gastric and duodenal perforations. The time between primary gastric-restrictive surgery and ulcer perforation varied from 20 days to 12 years. All patients presented with upper abdominal pain. The classical radiological sign of perforated peptic ulcer, free air under the diaphragm, did not occur in any patient. Nine patients were initially treated by primary closure of the perforation with subsequent definitive ulcer therapy by vagotomy, pyloroplasty, or gastrectomy. One case, initially treated elsewhere, was managed by placement of a Malecot catheter through the duodenal perforation, gastrostomy, and peritoneal drainage. One recent case remains symptom-free on H2 blockers after simple closure. There was no mortality. Six cases were previously reported in the literature with a 33 per cent mortality rate.

  12. Postoperative management of dogs with gastric dilatation and volvulus.

    2014-09-01

    The objective of the study was to review the veterinary literature for evidence-based and common clinical practice supporting the postoperative management of dogs with gastric dilatation and volvulus (GDV). GDV involves rapid accumulation of gas in the stomach, gastric volvulus, increased intragastric pressure, and decreased venous return. GDV is characterized by relative hypovolemic-distributive and cardiogenic shock, during which the whole body may be subjected to inadequate tissue perfusion and ischemia. Intensive postoperative management of the patients with GDV is essential for survival. Therapy in the postoperative period is focused on maintaining tissue perfusion along with intensive monitoring for prevention and early identification of ischemia-reperfusion injury (IRI) and consequent potential complications such as hypotension, cardiac arrhythmias, acute kidney injury (AKI), gastric ulceration, electrolyte imbalances, and pain. In addition, early identification of patients in need for re-exploration owing to gastric necrosis, abdominal sepsis, or splenic thrombosis is crucial. Therapy with intravenous lidocaine may play a central role in combating IRI and cardiac arrhythmias. The most serious complications of GDV are associated with IRI and consequent systemic inflammatory response syndrome and multiple organ dysfunction syndrome. Other reported complications include hypotension, AKI, disseminated intravascular coagulation, gastric ulceration, and cardiac arrhythmias. Despite appropriate medical and surgical treatment, the reported mortality rate in dogs with GDV is high (10%-28%). Dogs with GDV that are affected with gastric necrosis or develop AKI have higher mortality rates. Copyright © 2014 Elsevier Inc. All rights reserved.

    Tavares, A B; Almeida, A G; Viveiros, F A; Cidade, C N; Barbosa, J M

    2011-05-10

    Epithelioid haemangioendothelioma (EHE) is a rare tumour of vascular origin, characterised by celular proliferation, endotelial, epitelioid or hystiocitoid. It may develop in any organ, but it is more common in lung and liver. Surgery is the recommended treatment; however, in case of a potentially benign situation, an expectant attitude should be adopted. The case reports a 71-year-old female who underwent a laparotomy for a colonic adenocarcinoma. During surgery, a polypoid lesion in the dependency of the gastric wall was found incidentally, which was removed. Histopathology and immunohistochemical analysis confirmed the diagnosis of EHE. Gastric vascular neoplasms represent about 0.9-3.3% of all gastric tumours. Usually have a good prognosis, but due to the borderline biological behaviour of these tumours, it is important to have a detailed clinical evaluation at follow-up of these patients.

    Gastric volvulus in children is uncommon, and characteristic radiographic findings might not be recognized. To present the spectrum of clinical and imaging findings, correlate the type of gastric volvulus with clinical outcome, and identify imaging findings to aid in early diagnosis. Medical records and imaging findings of ten children with gastric volvulus were reviewed. Imaging included abdominal radiographs, upper gastrointestinal (UGI) series, and CT. The diagnosis (organoaxial, mesenteroaxial or mixed type) was made on the UGI series (n = 9) and CT (n = 1), and confirmed surgically in seven children. Patients were classified based on presentation: four acute, four chronic, and two neonatal. All of the acute group (three mesenteroaxial and one mixed type) had abnormal radiographic findings: three spherical gastric distension, four paucity of distal gas, three elevated left hemidiaphragm, one overlapping pylorus and gastric fundus, one unusual nasogastric tube course, and one situs inversus. All underwent emergent surgery. Three had diaphragmatic abnormalities. One had heterotaxy. Patients in the chronic group (three organoaxial, one mesenteroaxial) had long-standing symptoms. Most had associated neurologic abnormalities. In the neonatal group, organoaxial volvulus was found incidentally on the UGI series. A spectrum of findings in gastric volvulus exists. Mesenteroaxial volvulus has greater morbidity and mortality. Radiographic findings of spherical gastric dilatation, paucity of distal gas and diaphragmatic elevation are suggestive of acute volvulus, particularly in patients with predisposing factors. (orig.)

    Full Text Available Summary Background The aim of this study was to test the effect of different pulse frequencies and amplitudes during gastric stimulation (GS on gastric emptying in the rat. Methods GS was performed in 2 groups of laparotomized rats: healthy control animals, and rats with acute diabetes. The effects of four pulse frequencies (0.5, 1, 10, 20 Hz and three pulse amplitudes (5, 20, 40 mA were tested. The volumes emptied from the stomach after the oro-gastric instillation of a nutrient solution were compared to those obtained in animals without GS. Intragastric pH values were assessed under basal conditions and after GS. Results In both groups, GS increased emptied volumes compared to conditions without stimulation (p Conclusions Although both pulse frequency and amplitude should be considered during GS, frequency appears to be the most critical point. The possibility of increasing gastric emptying by electrical stimulation in diabetic rats suggests potential clinical applications for this method.

  17. Gastric Perforation and Phlegmon Formation by Foreign Body Ingestion

    Directory of Open Access Journals (Sweden)

    Albert Alejandro Avila Alvarez

    2014-08-01

    Full Text Available This is a case report of foreign body ingestion in a suicide attempt resulting in gastric perforation and phlegmon formation during a subsequent 6 month period that eventually required surgical intervention. The patient had a prolonged course because she did not report a history of foreign body ingestion and the initial evaluating physicians had no suspicion about possible foreign body ingestion and may have missed important findings on physical examination. Gastric perforation by a foreign object  may have a slow course rather than presenting acute abdomen. The realization of a proper physical examination in the emergency department is key to an accurate diagnosis.

    Gastric cancer is among the most common human malignancies and the second leading cause of cancer-related death. The different epidemiologic and histopathology of subtypes of gastric cancer are associated with different genomic patterns. Data suggests that gene expression patterns of proximal, distal gastric cancers-intestinal type, and diffuse/signet cell are well separated. This review summarizes the genetic and epigenetic changes thought to drive gastric cancer and the emerging paradigm of gastric cancer as three unique disease subtypes.

    Gastric rupture after blunt abdominal trauma is a rare injury with few reports in the literature. The purpose of this study was to review our experience with blunt gastric injuries and compare outcomes with small bowel or colon injuries. All patients with hollow viscus perforations after blunt abdominal trauma from 1992 to 2005 at our level I trauma center were reviewed. Of 35,033 blunt trauma admissions, there were 268 (0.7%) patients with a total of 319 perforating hollow viscus injuries, 25 (0.07%) of which were blunt gastric injuries. When compared with the small bowel or colon injuries, the blunt gastric injury group had a higher Injury Severity Score (22 versus 17, P = 0.04), more patients with a chest Abbreviated Injury Score greater than 2 (36% versus 12%, P < 0.01), and a shorter interval from injury to laparotomy (221 versus 366 minutes, P = 0.017). Multivariate analysis identified five independent risk factors for mortality: age older than 55 years, head Abbreviated Injury Score greater than 2, chest Abbreviated Injury Score greater than 2, the presence of hypotension on admission, and Glasgow Coma Scale 8 or less. The results of this study suggest that mortality in patients with blunt hollow viscus injuries can be attributed to concurrent head and chest injuries, but not the specific hollow viscus organ that is injured.

    Gastric neuroendocrine tumours (NETs) are increasingly recognised, and management decisions may be difficult due to an incomplete understanding of aetiology, natural history and optimum therapy. This article presents a current understanding based on recent advances in epidemiology, classification, molecular profiling, and treatment. Relevant medical literature was identified from searches of PubMed and references cited in appropriate articles identified. Selection of articles was based on peer review, journal and relevance. Gastric NETs may be divided into three clinical prognostic groups: type I is associated with autoimmune atrophic gastritis and hypergastrinaemia, type II is associated with Zollinger-Ellison syndrome, and type III lesions are gastrin-independent, have the greatest metastatic potential and poorest prognosis. There has been an increased frequency of gastric NETs reported. Management approaches have evolved in parallel with advances in endoscopic staging and surgery, as well as improved understanding of the biology and natural history of NETs. Gastric NETs present a spectrum of activity from indolent tumours to metastatic malignancy. Treatment decisions for patients must be individualised and are best managed by a multidisciplinary team approach. The current evidence base is limited to small series and efforts to treat patients within clinical networks of expertise are warranted. Copyright © 2012 S. Karger AG, Basel.

    Because various mastication-related factors influence gastric activity, the functional relationship between mastication and gastric function has not been fully elucidated. To investigate the influence of mastication on gastric emptying and motility, we conducted a randomized trial to compare the effects of mastication on gastric emptying and gastric myoelectrical activity under conditions that excluded the influences of food comminution, taste, and olfaction. A (13)C-acetate breath test with electrogastrography and electrocardiography was performed in 14 healthy men who ingested a test meal with or without chewing gum. Autonomic nerve activity was evaluated by fluctuation analysis of heart rate. Gastric emptying was significantly delayed in the 'ingestion with mastication' group. Gastric myoelectrical activity was significantly suppressed during mastication and increased gradually in the post-mastication phase. A decrease in the high-frequency power of heart rate variability was observed coincidentally with gastric myoelectrical activity suppression. These findings suggest that initial gastric emptying is suppressed by mastication, and that the suppression is caused by mastication-induced inhibition of gastric activity (UMIN Clinical Trial Registration no. UMIN000005351).

    Gastric heterotopias beyond the ligament of Treitz though rare, should be thought of in the differential diagnosis of polypoid lesions presenting with gastrointestinal bleed or obstructive symptoms especially in children and in the young. Here is a 24-year-old male with multifocal jejunal gastric heterotopias causing multiple strictures and perforation peritonitis. Patient presented with acute abdomen pain and an emergency laparotomy was performed revealing jejunum with multiple strictures and perforation, followed by jejunal resection. On gross examination polypoid mucosa was noted at the stricture sites which showed heterotopic gastric mucosa on microscopy. Jejunal gastric heterotopias are extremely rare with less than ten reported cases and those presenting with multiple strictures are even rarer. To our knowledge this is the second case of jejunal gastric heterotopia presenting with multiple strictures.

While proton pump inhibitors have been widely used for blocking acid-producing enzymes, this approach can cause various adverse effects. Reported herein is a new microdevice, consisting of magnesium-based micromotors which can autonomously and temporally neutralize gastric acid through efficient chemical propulsion in the gastric fluid by rapidly depleting the localized protons. Coating these micromotors with a cargo-containing pH-responsive polymer layer leads to autonomous release of the encapsulated payload upon gastric-acid neutralization by the motors. Testing in a mouse model demonstrate that these motors can safely and rapidly neutralize gastric acid and simultaneously release payload without causing noticeable acute toxicity or affecting the stomach function, and the normal stomach pH is restored within 24 h post motor administration. © 2017 Wiley-VCH Verlag GmbH & Co.

    Full Text Available The finding of gas within the gastric wall is not a disease by itself, rather than a sign of an underlying condition which could be systemic or gastric. We present the case of a woman identified with gastric emphysema secondary to the administration of high doses of steroids, with the purpose of differentiating emphysematous gastritis versus gastric emphysema due to the divergent prognostic implications. Gastric emphysema entails a more benign course, opposed to emphysematous gastritis which often presents as an acute abdomen and carries a worse prognosis. Owing to the lack of established diagnostic criteria, computed tomography is the assessment method of choice. Currently no guidelines are available for the management of this entity, since the evidence is limited to a few case series and a considerable number of single case reports.

    Background: Survival rates after curative surgery for gastric cancer are disappointing. Therefore adjuvant therapeutic strategies are required. Aim: To analyze survival and side effects of treatment among gastric cancer patients treated with adjuvant chemoradiotherapy after curative resection of gastric adenocarcinoma. Material and methods: Retrospective review of medical records of 74 patients aged 20 to 74 years, treated with complete resection of gastric adenocarcinoma followed by adjuvant chemo radiation. Survival analysis was based on the records and information from the National Mortality Registry. Results: Five years survival fluctuated from 50% among patients in stage 1B to 25% among those is stage IV. Significant acute toxicity was observed in 23 patients (31%). No patients died due to acute toxicity. Eleven patients (16.4%) developed significant late toxicity, with two possible deaths related to treatment. Conclusions: Postoperative chemoradiotherapy is feasible in our experience. Continuos infusion of 5- fluoruracil is recommended to reduce toxicity

    Full Text Available Flos Lonicerae is one of the oldest and most commonly prescribed herbs in Eastern traditional medicine to treat various inflammatory diseases. In the present study, we investigated the effects of ethyl acetate fraction of Flos Lonicerae (GC-7101 on experimental gastric ulcer models and its mechanisms of action in gastric ulcer healing. The pharmacological activity of GC-7101 was investigated in rats on HCl/EtOH, indomethacin, water immersion restraint stress induced acute gastric ulcer, and acetic-acid-induced subchronic gastric ulcer. To determine its gastroprotective mechanisms, gastric wall mucus secretion, mucosal PGE2, mucosal NO content, nuclear translocation of NF-κB, mRNA expression of inflammatory cytokines, lipid peroxidation and glutathione content, and superoxide dismutase and catalase activities were measured. GC-7101 significantly attenuated development of acute gastric ulcer and accelerated the healing of acetic-acid-induced subchronic gastric ulcer. In HCl/EtOH-induced gastric ulcer, GC-7101 markedly enhanced gastric wall mucus content which was accompanied by increased mucosal PGE2 and NO production. Furthermore, treatment of GC-7101 exhibited anti-inflammatory and antioxidant activities as evidenced by decreased myeloperoxidase activity, NF-κB translocation, inflammatory cytokines mRNA expression, and lipid peroxidation and increased glutathione content and superoxide dismutase and catalase activities. These results demonstrated that GC-7101 possesses strong antiulcerogenic effect by modulating oxidative stress and proinflammatory mediators.

    The gastric epithelium is continuously regenerated by gastric stem cells, which give rise to various kinds of daughter cells, including parietal cells, chief cells, surface mucous cells, mucous neck cells, and enteroendocrine cells. The self-renewal and differentiation of gastric stem cells need delicate regulation to maintain the normal physiology of the stomach. Recently, it was hypothesized that cancer stem cells drive the cancer growth and metastasis. In contrast to conventional clonal ev...

    Gastric polyps are often an incidental finding on upper gastrointestinal endoscopy, with an incidence up to 5%. The majority of gastric polyps are asymptomatic, occurring secondary to inflammation. Prior reviews discussed Helicobacter pylori (H pylori)-associated singular gastric polyposis; however, we present a rare and unusual case of recurrent multiple benign gastric polyposis post H pylori eradication resulting in intermittent gastric outlet obstruction. A 70-year-old independent male, Chinese in ethnicity, with a background of diabetes mellitus, hypertension, and a simple renal cyst presented with a combination of melena, anemia, and intermittent vomiting of partially digested food after meals. Initial gastroscopy was positive for H pylori; thus he was treated with H pylori eradication and proton pump inhibitors. Serial gastroscopy demonstrated multiple sessile gastric antral polyps, the largest measuring 4 cm. Histopathologic examination confirmed a benign hyperplastic lesion. Computed tomography identified a pyloric mass with absent surrounding infiltration or metastasis. A distal gastrectomy was performed, whereby multiple small pyloric polyps were found, the largest prolapsing into the pyloric opening, thus explaining the intermittent nature of gastric outlet obstruction. Such polyps often develop from gastric ulcers and, if left untreated, may undergo neoplasia to form malignant cells. A distal gastrectomy was an effective choice of treatment, taking into account the polyp size, quantity, and potential for malignancy as opposed to an endoscopic approach, which may not guarantee a complete removal of safer margins and depth. Therefore, surgical excision is favorable for multiple large gastric polyps with risk of malignancy.

    Full Text Available Background: The aim of the study was to review the cases of all children who had gastric volvulus from 2002 to 2007 at a tertiary care centre in India and to compare the outcome of management with the reported series on gastric volvulus in a paediatric age group. Materials and Methods: This was a retrospective study of eight children with an age range between 10 days and 2 years who were managed for gastric volvulus between 2002 and 2007. The records of these patients were reviewed for clinical features, investigations, management and outcome. Results: All patients were less than 3 years of age with female preponderance (n = 5. Three patients had acute presentation and three had acute-on-chronic symptoms, while two had chronic gastric volvulus. The commonest symptom was abdominal distension. Two patients were diagnosed by barium studies and six had clinical suspicion because of their symptoms and were confirmed intra-operatively. Seven had secondary gastric volvulus of organo axial type with associated pathologies as congenital diaphragmatic hernia (n = 5, Para oesophageal hiatus hernia (n = 2, and one had primary gastric volvulus in a postoperative period in an operated case for a tracheo-oesophageal fistula (n = 1. Seven patients were symptom free at follow-up; one patient succumbed due to septicaemia in the immediate post-operative period which was not related to the pathology of gastric volvulus. Conclusion: Gastric volvulus is a rare condition in children and requires prompt diagnosis and urgent intervention in acute presentation where it mimics acute abdomen and strong clinical suspicion.

    Despite its decreasing incidence overall, gastric cancer is still a challenging disease. Therapy is based mainly upon surgical resection when the tumour remains localised in the stomach. Conventional chemotherapy may play a role in treating micrometastatic disease and is effective as palliative therapy for recurrent or advanced disease. However, the knowledge of molecular pathways implicated in gastric cancer pathogenesis is still in its infancy and the contribution of molecular biology to the development of new targeted therapies in gastric cancer is far behind other more common cancers such as breast, colon or lung. This review will focus first on the difference of two well defined types of gastric cancer: intestinal and diffuse. A discussion of the cell of origin of gastric cancer with some intriguing data implicating bone marrow derived cells will follow, and a comprehensive review of different genetic alterations detected in gastric cancer, underlining those that may have clinical, therapeutic or prognostic implications.

    Intractable vomiting in an elderly patient is an emergency condition requiring prompt diagnosis and intervention. Acute gastric outlet obstruction due to gastric volvulus through Morgagni-type diaphragmatic hernia is an exceedingly rare cause of this nonspecific complaint. Our aim was to highlight that Morgagni hernia, although rare in adults, should be suspected in the appropriate clinical setting, and that a clue toward diagnosis often comes from routine chest and abdominal x-ray studies. In addition, we emphasize the atypical radiological findings and importance of emergency surgical intervention in such a case. We describe the case of a 78-year-old woman who presented to the Emergency Department with a 4-day history of intractable vomiting, and with no definitive clue to the diagnosis on examination. Her routine chest and abdomen x-ray studies suggested abnormal air-fluid level at right hemithorax, which prompted a computed tomography (CT) scan of the abdomen and an upper gastrointestinal contrast study. Gastric volvulus through a foramen of Morgagni was diagnosed and transthoracic reduction of the contents was performed, along with repair of the defect. A symptomatic Morgagni hernia in adults, although rare, can present with a variety of symptoms ranging from nonspecific complaints of bloating and indigestion to the more severe complaint of intestinal obstruction. Gastric volvulus and obstructive features are less frequently reported as acute complications of these hernias, which need early identification and intervention. Copyright © 2013 Elsevier Inc.

    Gastric emptying of a semiliquid test meal with 5 MBq /sup 99m/Tc-sulfur colloid as a marker was measured in 97 chronic dyspeptic patients and 16 healthy subjects. A comparison of half emptying time between both showed that chronic dyspeptic patients empty semiliquid meal at a significantly (p < 0.005) slower rate (at 70 +- 33 min) than healthy controls (at 52 x 20 min). The studies indicate that gastric stasis in chronic dyspepsia is not caused by inflammatory changes in gastric or duodenal mucosa nor by different gastric acid secretion. The presence of stasis cannot be predicted sufficiently by anamnestic complaints or endoscopic findings. (author)

    Gastric Schwannoma is a rare benign intramural tumor arising from the stomach, and it accounts for only 0.1% of all the different kinds of gastric neoplasms, and it's less than 4% of all the benign gastric tumors. This tumor is very difficult to differentiate from the other mesenchymal tumors by the clinical, endoscopic and radiologic findings. In this study, we demonstrate the appearance of this tumor on endoscopic ultrasound and contrast-enhanced abdomen CT. We also show the histopathologic findings of a surgically confirmed gastric Schwannoma that was located in the proper muscle layer

    The gastroprotective mechanism of the natural diterpene ferruginol was assessed in mice and rats. The involvement of gastric prostaglandins (PGE(2)), reduced glutathione, nitric oxide or capsaicin receptors was evaluated in mice either treated or untreated with indometacin, N-ethylmaleimide (NEM), N-nitro-L-arginine methyl ester (L-NAME) or ruthenium red, respectively, and then orally treated with ferruginol or vehicle. Gastric lesions were induced by oral administration of ethanol. The effects of ferruginol on the parameters of gastric secretion were assessed in pylorus-ligated rats. Gastric PGE(2) content was determined in rats treated with ferruginol and/or indometacin. The reduction of gastric glutathione (GSH) content was determined in rats treated with ethanol after oral administration of ferruginol, lansoprazole or vehicle. Finally, the acute oral toxicity was assessed in mice. Indometacin reversed the gastroprotective effect of ferruginol (25 mg kg(-1)) but not NEM, ruthenium red or L-NAME. The diterpene (25 mg kg(-1)) increased the gastric juice volume and its pH value, and reduced the titrable acidity but was devoid of effect on the gastric mucus content. Ferruginol (25, 50 mg kg(-1)) increased gastric PGE(2) content in a dose-dependent manner and prevented the reduction in GSH observed due to ethanol-induced gastric lesions in rats. Single oral doses up to 3 g kg(-1) ferruginol did not elicit mortality or acute toxic effects in mice. Our results showed that ferruginol acted as a gastroprotective agent stimulating the gastric PGE(2) synthesis, reducing the gastric acid output and improving the antioxidant capacity of the gastric mucosa by maintaining the GSH levels.

Materials and Methods. Esophageal and gastric cancer cases, who underwent surgery between January 1, 2012, and December 31, 2013, were examined. Pathology reports of the patients and presence of Helicobacter pylori (HP were recorded. Surveys were filled by face to face meeting or telephone call. Control group was created with randomly selected individuals without any cancer diagnosis having age, gender, and socioeconomic characteristics similar to patient group. All data were analyzed using SAS.9.3 statistical programme. Results. Compared with the control group, herby cheese consumption (a component of eating habits and smoking were significantly higher in the patient group (P<0.001. Tandoor exposure is compared in terms of female gender, and significant difference was found between the groups (P=0.0013. As a result of the analysis with logistic regression more than 150 gr of herby cheese consumption per day was found to increase the cancer risk (odds ratio 1.017; 95% CI: 1.012–1.022. Conclusion. A high consumption of herby cheese, cooking bread on tandoor, and heavy smoking were seen to be important risk factors for esophageal and gastric cancers.

    Gastric varices that arise secondary to the splenic vein occlusion can result in gastrointestinal hemorrhaging. Endoscopic color Doppler ultrasonography (ECDUS) was performed in 16 patients with gastric varices secondary to splenic vein occlusion. This study retrospectively evaluated the role of ECDUS in the diagnosis of gastric varices secondary to splenic vein occlusion. Thirteen patients had co-existing pancreatic diseases: 8 with chronic pancreatitis, 4 with cancer of the pancreatic body or tail and 1 with severe acute pancreatitis. Of the remaining 3 patients, 1 had myeloproliferative disease, 1 had advanced gastric cancer, and the third had splenic vein occlusion due to an obscure cause. The endoscopic findings of gastric varices were: variceal form (F) classified as enlarged tortuous (F2) in 12 cases and large, coil-shaped (F3) in 4 cases, and positive for erosion or red color sign of the variceal surface in 4 cases and negative in 12 cases. ECDUS color flow images of gastric variceal flow clearly depicted a round fundal region at the center, with varices expanding to the curvatura ventriculi major of the gastric body in all 16 cases. The velocities of F3 type gastric varices were significantly higher than those of the F2 type. The wall thickness of varices positive for erosion or red color sign was significantly less than the negative cases. I conclude that ECDUS color flow images of gastric variceal flow depicted specific findings of gastric varices secondary to splenic vein occlusion at the round fundal region at the center, with varices expanding to the curvatura ventriculi major of the gastric body.

  10. A case report of gastric lymphocytic phlebitis, a rare mimic for malignancy

    Directory of Open Access Journals (Sweden)

    Daniel L. Chan

    Full Text Available Introduction: Lymphocytic phlebitis is a benign condition characterised by inflammation of the veins and rarely affects the gastrointestinal tract. Reported cases present as acute abdomen and involve the colon or small intestine. We report the fourth case of gastric lymphocytic phlebitis in the literature. Presentation of case: A 74-year-old female presented with eight weeks of abdominal pain. Findings at endoscopy were suggestive of a malignant ulcer on the greater curvature of antrum, while biopsies showed chronic gastritis without malignancy. Appearance at diagnostic laparoscopy was consistent with a malignant gastric ulcer with serosal changes. Due to persistent pain and the macroscopic appearance, she proceeded to have an open subtotal gastrectomy and D2 lymph node clearance. Despite macroscopic appearance, the microscopic examination demonstrated no malignancy, and was consistent with lymphocytic phlebitis with overlying ulceration. Discussion: This case was a mimic for gastric malignancy, with the benign diagnosis only being made after surgical resection. Gastric lymphocytic phlebitis is a rare differential diagnosis for gastric ulcers when biopsies are negative, although preoperative diagnosis is difficult given the lesions do not involve the mucosa. Conclusion: If clinical history and endoscopic findings are suspicious for malignancy, despite normal biopsies, an aggressive surgical resection remains reasonable given the rarity gastric lymphocytic phlebitis.

    To describe the successful management of gastric dilatation and volvulus (GDV) in a red panda. Clinical report. Red panda diagnosed with GDV. A 12-year-old male red panda (Ailurus fulgens) was evaluated for acute onset inappetence, staggering, collapse, and tachypnea. Gastric dilatation and volvulus (GDV) was diagnosed by radiography, abdominal ultrasonography, and exploratory celiotomy. Torsion of the stomach was corrected and an incisional gastropexy performed to prevent recurrence. No organs were devitalized, no other abnormalities detected, and the red panda recovered fully within 72 hours. GDV should be considered as a differential diagnosis for red pandas presenting with acute onset of unspecific signs such as collapse, inappetence, and abdominal distension. GDV in red pandas can be diagnosed and successfully treated as described in dogs. © Copyright 2014 by The American College of Veterinary Surgeons.

    Preclinical studies show that the glucagon-like peptide-1 (GLP-1) receptor antagonist, exendin (9-39), can reduce acute emesis induced by cisplatin. In the present study, we investigate the effect of exendin (9-39) (100 nmol/24 h, i.c.v), on cisplatin (5 mg/kg, i.p.)-induced acute and delayed emesis and changes indicative of 'nausea' in ferrets. Cisplatin induced 37.2 ± 2.3 and 59.0 ± 7.7 retches + vomits during the 0-24 (acute) and 24-72 h (delayed) periods, respectively. Cisplatin also increased ( P Advanced multifractal detrended fluctuation analysis revealed that the slow wave signal shape became more simplistic during delayed emesis. Cisplatin did not affect blood pressure (BP), but transiently increased heart rate, and decreased heart rate variability (HRV) during acute emesis; HRV spectral analysis indicated a shift to 'sympathetic dominance'. A hyperthermic response was seen during acute emesis, but hypothermia occurred during delayed emesis and there was also a decrease in HR. Exendin (9-39) did not improve feeding and drinking but reduced cisplatin-induced acute emesis by ~59 % ( P waves may represent a novel approach to treat the side effects of chemotherapy.

    Animal models have greatly enriched our understanding of the molecular mechanisms of numerous types of cancers. Gastric cancer is one of the most common cancers worldwide, with a poor prognosis and high incidence of drug-resistance. However, most inbred strains of mice have proven resistant to gastric carcinogenesis. To establish useful models which mimic human gastric cancer phenotypes, investigators have utilized animals infected with Helicobacter species and treated with carcinogens. In addition, by exploiting genetic engineering, a variety of transgenic and knockout mouse models of gastric cancer have emerged, such as INS-GAS mice and TFF1 knockout mice. Investigators have used the combination of carcinogens and gene alteration to accelerate gastric cancer development, but rarely do mouse models show an aggressive and metastatic gastric cancer phenotype that could be relevant to preclinical studies, which may require more specific targeting of gastric progenitor cells. Here, we review current gastric carcinogenesis mouse models and provide our future perspectives on this field. PMID:24216700

    Full Text Available Introduction: Gastric volvulus is a surgical condition that should be recognised promptly to prevent life-threatening gastric ischaemia and perforation in acute setting. There are two peak age group of incidence with children less than one year old and at fifth decade.1 The mortality rates for acute gastric volvulus remain high with reported range from 30% to 50% signifying the need of early diagnosis and treatment.2 These case series reported modified minimal invasive approach for symptomatic chronic gastric volvulus in a tertiary upper gastrointestinal unit in Singapore. Methods: Retrospective case series reviewed in single centre from 1st May 2016 to 1st May 2017 of clinical outcomes of modified minimally invasive approach and de-rotation of symptomatic chronic gastric volvulus. Results: Three symptomatic patients with evidence of gastric volvulus on CT-scan underwent minimally invasive repair with the aids of GastriSail™ Gastric positioning system. GastriSail™ was used for gastric volvulus de-rotation prior to repair definitely. Two patients had fundoplication done and one patient had gastropexy performed successfully. All patients started on blended diet post-operative day 1 and discharged well. Patient remained asymptomatic and nil recurrence at 3 months follow-up post-operation. Conclusion: Based on our experience, we advocate modified minimally invasive repair of chronic gastric volvulus as an alternative to traditional open surgical technique with acceptable good clinical outcomes.

    Iris metastasis in patients with gastric cancer is extremely rare. Herein, it is aimed to report on a patient with gastric adenocarcinoma and iris metastasis. A 65-year-old patient with the history of gastric cancer was admitted for eye pain and eye redness on his left eye. There was ciliary injection, severe +4 cells with hypopyon in the anterior chamber and a solitary, friable, yellow-white, fleshy-creamy vascularized 2 mm × 4 mm mass on the upper nasal part of the iris within the left eye. The presented patient's mass lesion in the iris fulfilled the criteria of the metastatic iris lesion's appearance. The ocular metastasis occurred during chemotherapy. Iris metastasis can masquerade as iridocyclitis with pseudohypopyon or glaucoma. In patients with a history of gastric cancer that present with an iris mass, uveitis, and high intraocular pressure, ocular metastasis of gastric cancer should be a consideration.

    Salah Termos

    Full Text Available Introduction: Gastric lipomas are unusual benign lesions and account for less than 1% of all tumours of the stomach and 5% of all gastrointestinal lipomas (Thompson et al.2003; Fernandez et al. 1983 [1,2]. Although predominantly asymptomatic and indolent; they may present with gastric outlet obstruction and upper gastrointestinal (GI bleeding owing to size and ulceration. Only a few cases have been reported, presenting large in size with massive GI bleeding (Alcalde Escribano et al. 1989; Johnson et al. 1981 [3,4]. Presentation of case: We report the case of a 62-year-old gentleman who presented to the emergency department with massive upper GI hemorrhage. He was initially resuscitated and stabilized. Later gastroscopy showed a large submucosal tumour (Fig. 1. Biopsy revealed adipose tissue. Computed tomography (CT scan of the abdomen and pelvis showed a huge well defined oval soft tissue lesion measuring about 16 × 8 × 8 cm. The mass noted a homogenous fat density arising from the posterior wall of stomach with no extramural infiltration (Fig. 2. The tumour was completely enucleated through an explorative gastrotomy incision (Fig. 4. Discussion and conclusion: Massive bleeding secondary to a giant gastric lipoma is a rare finding of a rare disease. The majority of cases in the literature result in major gastric resection. Familiarity with its radiological findings and a high index of suspicion can lead to proper diagnosis in the acute setting. If malignancy is carefully ruled out, stomach preserving surgery is an optimal treatment option. Keywords: Case report, Lipoma, Gastric lipoma, G I bleeding, Enucleation, Gastric resection

    Hyptis suaveolens is used by the traditional population in several parts of the world to treat inflammation, gastric ulcer and infection and is used as a crude drug to relieve symptoms related with gastric ulcer or gastritis in northeaster and central region of Brazil. the standardized ethanolic extract (Hs-EtOHE) and hexanic fraction (Hs-HexF) of Hyptis suaveolens (62,5, 125, 250 and 500 mg/kg) was evaluated in several models of acute gastric ulcers. The participation of NO was evaluated by pretreatment with L-NAME and non-protein sulfyhydryls by NEM in the gastroprotective effect. Hs-EtOHE and Hs-HexF markedly reduced the gastric lesions induced by all ulcerogenic agents (HCl/ethanol, ethanol, NSAIDs and hypothermic restraint-stress). Gastric ulcerations were exacerbated by administration of NEM suggesting that the gastroprotective mechanism of action of Hs-EtOHE and Hs-HexF involves sulfhydryl groups. Ours results show that an extract of Hyptis suaveolens, administered orally to rodents, present gastro protective activity in different models of acute of gastric ulcer and give some support to the reported claims on the use of this plant as a gastro protective agent. © 2013 Published by Elsevier Ireland Ltd.

    Functional neural gastrointestinal electrical stimulation (NGES) is a methodology of gastric electrical stimulation that can be applied as a possible treatment for disorders such as obesity and gastroparesis. NGES is capable of generating strong lumen-occluding local contractions that can produce retrograde or antegrade movement of gastric content. A feedback-controlled implantable NGES system has been designed, implemented and tested both in laboratory conditions and in an acute animal setting. The feedback system, based on gastric tissue impedance change, is aimed at reducing battery energy requirements and managing the phenomenon of gastric tissue accommodation. Acute animal testing was undertaken in four mongrel dogs (2 M, 2 F, weight 25.53 ± 7.3 kg) that underwent subserosal two-channel electrode implantation. Three force transducers sutured serosally along the gastric axis and a wireless signal acquisition system were utilized to record stimulation-generated contractions and tissue impedance variations respectively. Mechanically induced contractions in the stomach were utilized to indirectly generate a tissue impedance change that was detected by the feedback system. Results showed that increasing or decreasing impedance changes were detected by the implantable stimulator and that therapy can be triggered as a result. The implantable feedback system brings NGES one step closer to long term treatment of burdening gastric motility disorders in humans

    Full Text Available This study aimed to describe gastric ulcer in donkeys. 10 donkeys (Equus asinus were studied in Bodonal de la Sierra, Badajoz-Extremadura, Spain. They were referred for necropsy and dead due to non-digestive causes. 4 males and 6 females were examined. The ages were classified of 4-16 years old. The stomach and gastric mucosa was evaluated for classified Merrit, 2003. Samples of gastric tissue were collected. The samples fixed in formalin were processed by conventional histological techniques and examined by histopathology. None of the donkeys presented clinical signs for gastric ulcers syndrome. Of the 10 donkeys studied, 10% had Grade 0; 30% Grade 1; 40% Grade 2; 10% Grade 3; and 10% Grade 4. In 30% (3/10 parasites such as Gasterophilus sp. were observed. The histological slices revealed severe damage on the gastric mucosa, a loss of continuity of the gastric mucosa with corium exposure, and subchorionic edema with parakeratotic hyperkeratosis, together with a mixed lymphoplasmocytic mononuclear infiltrate. In conclusion, we reported gastric ulcers syndrome in donkeys in Spain.

    Curcumin is known to possess anti‑inflammatory properties. Despite the fact that curcumin is known to be a strong inhibitor of H+, K+‑ATPase activity, the mechanism underlying the curcumin‑induced inhibition of the transcription of the H+, K+‑ATPase α subunit in gastric mucosal parietal cells remains unclear. The present study investigated the possible mechanism by which curcumin inhibits stomach H+, K+‑ATPase activity during the acute phase of gastric ulcer disease. A rat model of stress‑induced gastric ulcers was produced, in which the anti‑ulcer effects of curcumin were examined. Curcumin‑induced inhibition of the H+, K+‑ATPase promoter via histone acetylation, was verified using a chromatin immunoprecipitation assay. The results showed that curcumin improved stress‑induced gastric ulcer disease in rats, as demonstrated by increased pH values and reduced gastric mucosal hemorrhage and ulcer index. These effects were accompanied by a significant reduction in the level of histone H3 acetylation at the site of the H+, K+‑ATPase promoter and in the expression of the gastric H+,K+‑ATPase α subunit gene and protein. In conclusion, curcumin downregulated the acetylation of histone H3 at the site of the H+, K+‑ATPase promoter gene, thereby inhibiting the transcription and expression of the H+, K+‑ATPase gene. Curcumin was shown to have a preventive and therapeutic effect in gastric ulcer disease.

    Full Text Available Total gastrectomy is an extremely rare procedure in children and experience with its replacement is very limited. We present two patients who had jejunal replacement due to total gastric necrosis. The first patient was a- 2-year-old boy who admitted with a history of caustic ingestion. He was taken operation because of gastric perforation and necrosis. Anastomosis was applied by using jejunal segments. The second patient was an 11-years-old girl who left diaphragmatic hernia and acute gastric volvulus. At laparotomy, Total gastrectomy and Hunt-Lawrence type gastroesophostomy were made. Reconstruction with jejunum is thought as a good option in total gastric necrosis according to our 2 patient experiences. [Cukurova Med J 2014; 39(2.000: 403-407

    We report a case of a 33-year-old woman with depression and suicidal ideation, treated successfully with electroconvulsive therapy (ECT) in the past. Since her previous course of ECT, she underwent gastric banding, a bariatric surgical procedure associated with increased risk of gastric regurgitation. Despite increasingly stringent measures to minimize the risk of regurgitation and aspiration during ECT, she had several episodes of regurgitation, the last of which precipitated an acute illness consistent with aspiration pneumonitis. We took additional precautions after each event, until she had no further episodes of regurgitation. We discuss the risk posed by the gastric band, the measures we implemented to minimize that risk, and our recommendations for assessment and management of post-gastric banding patients who present for ECT.

    AFP-producing gastric cancer(AFPGC) and hepatoid adenocarcinoma of the stomach (HAS) are two special subtypes of gastric cancer. There are both correlation and difference between them. AFPGC is usually identified as primary gastric cancer with serum AFP level more than 20 ng/ml or showed AFP positive staining by immunohistochemistry. The diagnosis of HAS is mainly dependent on the pathological character of hepatocellular carcinoma-like differentiation of gastric cancer. The morbidity of AFPGC and HAS are rather low, especially the incidence of HAS is about 1%. The prognoses of these two subtypes are poorer than that of common gastric adenocarcinoma, due to a high incidence rate of liver metastasis and lymph node metastasis. With the development of next-generation sequencing and other genomic technologies, gastric cancers, including these two rare subtypes, are now being investigated in more detail at the molecular level. Treatment remains the biggest challenge, early diagnosis and radical resection can dramatically improve patients'prognosis. Monitoring serum AFP and abdominal imaging examination during follow-up is important for early detection of liver metastasis. In combination with local treatment methods such as transarterial chemoembolization and radiofrequency ablation of liver may further extend patients'survival time. Targeted therapy owes a great potential value in the future.

    The incidence of gastrointestinal stromal tumours (GIST) has increased in recent years. A number of authors have attempted to define the actual nature of these tumours. Immunohistochemistry highlighting the positivity of tyrosine-kinase (CD117/c-Kit) has revealed the difference between gastrointestinal stromal tumours and other mesenchymal tumours and, therefore, the possibility of medical rather than surgical therapy. We retrospectively reviewed 19 patients affected by primary gastric GIST, who underwent surgery in recent years with subsequent follow-up. Gastroscopy and gastrointestinal tract radiography were used not only to obtain the diagnosis but also to establish the size, density, contours, ulceration, regional lymphadenopathy, mesenteric infiltration and the presence of metastases. The aim of this study was to evaluate the roles of endoscopy and radiology in this pathology and the advantages and limitations of each individual technique.

    There have been sporadic reports about synchronous as well as metachronous gastric adenocarcinoma and primary gastric lymphoma. Many reports have dealt with metachronous gastric adenocarcinoma in mucosa-associated lymphoid tissue lymphoma of stomach. But to our knowledge, there have been no reports that document the increased incidence of metachronous gastric adenocarcinoma in patients with gastric diffuse large B-cell lymphoma. This retrospective study was conducted to estimate the incidence of metachronous gastric adenocarcinoma after primary gastric lymphoma treatment, especially in diffuse large B-cell lymphoma. The retrospective cohort study of 139 primary gastric lymphoma patients treated with radiotherapy at our hospital. Mean observation period was 61.5 months (range: 3.7-124.6 months). Patients profile, characteristics of primary gastric lymphoma and metachronous gastric adenocarcinoma were retrieved from medical records. The risk of metachronous gastric adenocarcinoma was compared with the risk of gastric adenocarcinoma in Japanese population. There were 10 (7.2%) metachronous gastric adenocarcinoma patients after treatment of primary gastric lymphomas. It was quite high risk compared with the risk of gastric carcinoma in Japanese population of 54.7/100,000. Seven patients of 10 were diffuse large B-cell lymphoma and other 3 patients were mixed type of diffuse large B-cell lymphoma and mucosa associated lymphoid tissue lymphoma. Four patients of 10 metachronous gastric adenocarcinomas were signet-ring cell carcinoma and two patients died of gastric adenocarcinoma. Metachronous gastric adenocarcinoma may have a more malignant potential than sporadic gastric adenocarcinoma. Old age, Helicobacter pylori infection and gastric mucosal change of chronic gastritis and intestinal metaplasia were possible risk factors for metachronous gastric adenocarcinoma. There was an increased risk of gastric adenocarcinoma after treatment of primary gastric lymphoma

  8. Gastric Adenomyoma: The Unexpected Mimicker

    2017-01-01

    Full Text Available Gastric adenomyoma is a rare benign tumor composed of epithelial structures and smooth muscle stroma. Here, we report an unusual case of gastric adenomyoma mostly composed of smooth muscle that was incidentally found during a laparoscopic intervention. On radiology, it mimicked an acquired hypertrophic pyloric stenosis in an adult patient, and pathologically it resembled a pure smooth muscle hamartoma. Complete submission of the lesion for histology was necessary to find the epithelial component and make the right diagnosis. As a mimicker of benign and malignant entities, gastric adenomyoma is usually an unexpected finding after surgery. The aim of this report is to analyze this adenomyoma variant in the setting of an unexplained thickening of the gastric wall, with explanations concerning histogenesis and biological potential.

    627 cases of gastric cancer treated surgically during the last 5 years, at the Hospital Nacional "Edgardo Rebagliati Martins" from Instituto Peruano de Seguridad Social (Lima-Perú) were revised. 4 of the patients had been operated before of hemigastrectomy or antrectomy with pyloroplasty for peptic ulcer. The time between the first operation and diagnosis of cancer of the gastric stump was more than 20 years. 3 of these cases were able to be resected. The international incidence of cancer in the gastric stump is 1.1% to 9.2% according to different authors. The risk is higher after 15 years. In the pathogenesis are advocated the lower gastric acidity, biliary reflux, the presence of bacteria, the formation of nitrosamines, intestinal metaplasia, etc. Is necessary to perform periodic endoscopic survey in patients who were treated surgically of peptic ulcer with antrectomy or hemigastrectomy with more than 15 years of evolution.

    Cross-sectional gastric antral area (GAA) measurements by ultrasonography (US) have been proposed for preoperative assessment of gastric volume in adults but not been validated in children. This study investigates whether in children gastric volumes can be predicted by US performed in different patient positions. Gastric fluid and air volumes were examined by magnetic resonance imaging before or up to 120 min after ingestion of 7 ml·kg(-1) diluted raspberry syrup in healthy volunteers who had fasted overnight. GAA was measured with US three times each in supine (SUP), elevated 45° degree supine (E45) and right decubital (RDC) position using imaging planes defined by vascular landmarks. Correlation coefficients (Pearson) between GAA and gastric volumes were calculated and Bland-Altman analysis performed. Sixteen children aged from 6.4 to 12.8 (9.2) years were included in 23 examinations: 6 after overnight fasting, 3 directly after, and 14 with a delay of 74 ± 35 min after fluid intake. GAA was 221 ± 116, 218 ± 112, and 347 ± 188 mm(2) for SUP, E45, and RDC position, respectively. The best correlation between body weight corrected total gastric/gastric fluid volume (TGV(w)/GFV(w)) with GAA was found for RDC position (R = 0.79; P < 0.01/R = 0.78; P < 0.01). Bias and precision of calculated and measured GFV(w) was 0 ± 2.8 ml·kg(-1). Correlations between GAA and TGV(w) or GFV(w) in children are best in the RDC position, but not sufficient to predict GFV(w) with a given GAA. Interpretation of isolated GAA values may be misleading. © 2011 Blackwell Publishing Ltd.

    Abnormal gastric wall configurations in 27 cases of cause-unknown acute gastritis were studied roentgenographically with reference to their causative origins. Studies were made on roentgenograms (abnormal gastric wall configurations), endoscopic findings and extension of lesions of the subjected cases. Gastric contour showed 'staying', 'thumbprinting', 'undulate configuration' and 'squarish undulation', while 'chimney-like' finding suggestive of poor gastric wall stretch was observed in the whole antral region as well. The widened angulus ventriculi and expanded pyloric ring (insufficient constriction) were also seen. In some cases the lesion extended over to the duodenum and, as in the cases of acute gastritis, duodenal wall 'staying', 'thumbprinting' and varied duodenal wall undulation were seen in addition to edema and morphological changes of the Kerkring's folds. The lesions in the studied patients mostly extended from an epicenter of the antrum upward to the gastric corpus and downward near to Vater's papilla in the descending part of the duodenum. The affected regions were clearly distinguishable. It has been known that above-described roentgenographical findings in our studied patients were similar in part to those known in experimental studies carried out on animals with ischemic digestive tract. This strongly suggests that some of our patients had developed the disease due to ischemic causes. There were some discrepancies between roentgenographical (abnormal gastric wall configuration) and endoscopic findings in some studied patients. It has been our belief that abnormal gastric wall configuration reflects lesions in the inner part of the wall and, accordingly, roentgenographical examinations, as well as endoscopy, should be performed for the purpose of making correct diagnosis. It is also to be emphasized that angiography should be carried out on patients with relapsing acute gastritis without any specific cause. (author)

    Scrub typhus, or tsutsugamushi fever, is a zoonosis of rural Asia and the western Pacific islands. The causative organism, Orientia (formerly Rickettsia) tsutsugamushi, is transmitted to humans by the bite of a larval Leptotrombidium mite (chigger). Scrub typhus may have gastrointestinal presentations, such as acute acalculous cholecystitis, duodenal ulcer perforation, peritonitis and gastric ulceration. Acute pancreatitis with scrub typhus has been reported rarely. We report a patient of scrub typhus complicated by acute pancreatitis and acute kidney injury. © The Author(s) 2016.

    Full Text Available Gastric bezoars are rare and are usually found incidentally. They can sometimes cause severe complications, including gastric outlet obstruction (GOO or gastric pneumatosis (GP. In cases of bezoars with GP, the optimal treatment strategy has not yet been defined. We report the case of an 89-year-old man with a history of type 2 diabetes mellitus and hypertension who presented to our emergency room with a 2-day history of upper abdominal pain, nausea, and vomiting. Physical examination revealed no rebound tenderness or guarding, and laboratory values revealed no elevation of the serum lactate level. A computed tomography scan of the abdomen showed a dilated stomach with significant fluid collection, GOO, and GP due to a 42 × 40 mm mass composed of fat and air densities. Emergency esophagogastroduodenoscopy revealed two gastric bezoars, one of which was incarcerated in the pyloric region. We used various endoscopic devices to successfully break and remove the bezoars. We used endoscopic forceps and a water jet followed by an endoscopic snare to cut the bezoars into several pieces and remove them with an endoscopic net. Follow-up endoscopy confirmed that the gastric bezoar had been completely removed. As seen in this case, endoscopic treatment may be a safe and viable option for the extraction of gastric bezoars presenting with GOO and GP.

    Gastric cancer can be classified into two categories based on the absence or presence of symptoms at diagnosis. Differences in clinicopathological features and prognoses between asymptomatic gastric cancer (ACG) and symptomatic gastric cancer (SGC) can be used to inform diagnosis strategies and ultimately improve survival rates. All cases of gastric cancer (239 AGC, 323 SGC) diagnosed in our hospital between 1997 and 1999 were used in this study. ACG patients showed significantly higher frequency of males, cases of early cancer, cases found by a mass screening program, cases treated by endoscopic resection, cases treated by curative operation, cases of type 0 macroscopic finding, cases of histologically-differentiated type, and stage I cases. By contrast, SGC patients showed significantly higher numbers of cases treated by chemotherapy alone or best support care, cases of type 2, 3, and 4 macroscopic findings, cases occupying the whole stomach, and cases of stage II, III, IV. Statistically significant differences were also found for the 5-year survival rate (83.3% in AGC, 41.2% in SGC), the incidence of early cancer (90.1% in AGC, 83.7% in SGC), and for advanced cancer (38.7% in AGC, 22.7% in SGC). The higher incidence of advanced cases in SGC than in AGC (40.0% vs. 13.0%), coupled with the low 5-year survival rate of advanced SGC (22.7%), provides strong evidence of the importance of diagnosing gastric cancer during its asymptomatic period.

    After localized 300 kV X-irradiation of the rat stomach the stomach emptying time of a liquid and a solid test meal was examined with a non-invasive radiological method. In the acute period one to three weeks after irradiation with single doses between 10.7 and 21.3 Gy we observed a faster emptying of the liquid and a delayed emptying of the solid test meal. The faster emptying of the liquid test meal was treated successfully with atropin. In the chromic period we observed a delayed emptying of the liquid and of the solid test meal. These emptying disorders were treated partially successfully with the parasympathomimeticum carbachol and they were treated completeley successfully with the dopamine antagonist metoclopramide.

    Objective: To investigate the interventional therapy and its curative effect for progressing stage gastric cancer. Methods: two hundred and twelve patients with progressing stage gastric cancer were treated with arterial perfusion and arterial embolization. Gastric cardia cancer was treated through the left gastric artery and the left inferior phrenic artery or splenic artery. Cancers of lesser and greater gastric curvature was treated either through the left and right gastric arteries or common hepatic artery or through gastroduodenal artery, right gastroomental artery or splenic artery. Gastric antrum cancers were perfused through gastroduodenal artery or after the middle segmental embolization of right gastroomental artery. Results: One hundred and ninety three cases undergone interventional management were followed up. The CR + PR of gastric cardia cancer was 53.13%; gastric body cancer 44.44%; gastric antrum cancer 10%; recurrent cancer and remnant gastric cancer 0. There was no significant difference in outcome between gastric cardia cancer and gastric body cancer (P>0.05) but significant differences were shown both between gastric cardia cancer and gastric antrum cancer, and between gastric body cancer and gastric antrum cancer (P<0.05), with 1 year and 2 years survival rates of 81% and 56% respectively. Conclusion: The interventional therapeutic effect of progressing stage gastric cancers is different due to the different sites of the lesions in the gastric tissue. The curative effect of gastric cardia cancer and gastric body cancer is better than that of gastric antrum cancer, recurrent cancer and remnant gastric cancer. (authors)

    Although many genetic alterations have been reported in gastric cancer, it is not known whether all gastric tumors are capable of indefinite proliferative potential, e.g., immortality. The expression of telomerase and stabilization of telomeres are concomitant with the attainment of immortality in tumor cells; thus, the measurement of telomerase activity in clinically obtained tumor samples may provide important information useful both as a diagnostic marker to detect immortal cancer cells in clinical materials and as a prognostic indicator of patient outcome. Telomerase activity was analyzed in 66 primary gastric cancers with the use of a PCR-based assay. The majority of tumors (85%) displayed telomerase activity, but telomerase was undetectable in 10 tumors (15%), 8 of which were early stage tumors. Most of the tumors with telomerase activity were large and of advanced stages, including metastases. Survival rate of patients of tumors with detectable telomerase activity was significantly shorter than that of those without telomerase activity. Alterations of telomere length (reduced/elongated terminal restriction fragments) were detected in 14 of 66 (21%) gastric cancers, and all 14 had telomerase activity. Cellular DNA contents revealed that all 22 aneuploid tumors had detectable telomerase activity. The present results indicate that telomerase activation may be required as a critical step in the multigenetic process of tumorigenesis, and that telomerase is frequently but not always activated as a late event in gastric cancer progression.

    Traditional use of gastric residual volumes (GRVs), obtained by aspiration from a nasogastric tube, is inaccurate and cannot differentiate components of the gastric contents (gastric secretion vs delivered formula). The use of refractometry and 3 mathematical equations has been proposed as a method to calculate the formula concentration, GRV, and formula volume. In this paper, we have validated these mathematical equations so that they can be implemented in clinical practice. Each of 16 patients receiving a nasogastric tube had 50 mL of water followed by 100 mL of dietary formula (Osmolite HN, Abbott Laboratories, Columbus, OH) infused into the stomach. After mixing, gastric content was aspirated for the first Brix value (BV) measurement by refractometry. Then, 50 mL of water was infused into the stomach and a second BV was measured. The procedure of infusion of dietary formula (100 mL) and then water (50 mL) was repeated and followed by subsequent BV measurement. The same procedure was performed in an in vitro experiment. Formula concentration, GRV, and formula volume were calculated from the derived mathematical equations. The formula concentrations, GRVs, and formula volumes calculated by using refractometry and the mathematical equations were close to the true values obtained from both in vivo and in vitro validation experiments. Using this method, measurement of the BV of gastric contents is simple, reproducible, and inexpensive. Refractometry and the derived mathematical equations may be used to measure formula concentration, GRV, and formula volume, and also to serve as a tool for monitoring the gastric contents of patients receiving nasogastric feeding.

    Patients. All four obese morbidly patients underwent LRYGBP and presented a gastro-jejunal fistula after acute anastomotic leakage. During follow-up endoscopy the drain was found inside the gastric pouch. It was moved into the abdominal cavity. Fistula debit reduced significantly and closed. Results. Gastric leak closure in less than 24 hours was achieved in all, with complete resolution of symptoms. These patients benefited exclusively from endoscopic treatment. Conclusions. Endoscopy is useful and technically feasible in chronic fistulas. This procedure is a less invasive alternative to traditional surgical revision. Other therapeutic strategies can be used such as clips and fibrin glue. Drains should not be placed in contact with the anastomosis or stapled lines. Drain inclusion must be suspected when fistula debit suddenly arises. If so, endoscopy is indicated for diagnostic accuracy. Under endoscopy vision, the drain is gently removed from the gastric reservoir leading to sudden and complete resolution of the fistula.

    Full Text Available Candidiasis of the gastrointestinal tract most commonly involves the esophagus and rarely involves the stomach and small bowel. The association of gastric carcinoma with candidiasis is even rare and only a very few case reports are available. We present here a 40-year-old female who presented with complaints of gastric outlet obstruction who on endoscopy showed a malignant ulcer involving the lesser curvature. The histopathological examination of biopsy from the ulcer showed adenocarcinoma intestinal type along with yeast and pseudohyphae forms of candida species.

    Lymphocytic phlebitis is a benign condition characterised by inflammation of the veins and rarely affects the gastrointestinal tract. Reported cases present as acute abdomen and involve the colon or small intestine. We report the fourth case of gastric lymphocytic phlebitis in the literature. A 74-year-old female presented with eight weeks of abdominal pain. Findings at endoscopy were suggestive of a malignant ulcer on the greater curvature of antrum, while biopsies showed chronic gastritis without malignancy. Appearance at diagnostic laparoscopy was consistent with a malignant gastric ulcer with serosal changes. Due to persistent pain and the macroscopic appearance, she proceeded to have an open subtotal gastrectomy and D2 lymph node clearance. Despite macroscopic appearance, the microscopic examination demonstrated no malignancy, and was consistent with lymphocytic phlebitis with overlying ulceration. This case was a mimic for gastric malignancy, with the benign diagnosis only being made after surgical resection. Gastric lymphocytic phlebitis is a rare differential diagnosis for gastric ulcers when biopsies are negative, although preoperative diagnosis is difficult given the lesions do not involve the mucosa. If clinical history and endoscopic findings are suspicious for malignancy, despite normal biopsies, an aggressive surgical resection remains reasonable given the rarity gastric lymphocytic phlebitis.

    Operative repair of obstructive gastric volvulus is challenging. In high-operative risk patients with obstructive gastric volvulus, we perform laparoscopic reduction of gastric volvulus and anterior abdominal wall sutured gastropexy. This case series reports our experience with this operation. We reviewed the charts of all patients who presented with obstructive gastric volvulus and underwent laparoscopic gastropexy between 2007 and 2013. Eleven patients underwent laparoscopic gastropexy. Median age was 83 years (50 to 92). Six patients presented with chronic obstruction; 5 presented with acute obstruction. Median postoperative hospitalization was 2 days (1 to 39). Two patients required reoperation for displaced gastrostomy tubes. At median follow-up of 3 months (2 weeks to 57 months), all patients remained free of gastric obstructive symptoms and recurrent episodes of volvulus. Only 1 patient received nutrition via gastrostomy tube. Laparoscopic gastropexy can treat obstructed gastric volvulus in highoperative risk patients. Because of associated morbidity, gastrostomy tubes should be placed selectively. Copyright © 2015 Elsevier Inc. All rights reserved.

    The authors devised a novel method to automate the analysis of nuclear gastric emptying studies. Many previous methods have been used to measure gastric emptying but, are cumbersome and require continuing interference by the operator to use. Two specific problems that occur are related to patient movement between images and changes in the location of the radioactive material within the stomach. Their method can be used with either dual or single phase studies. For dual phase studies the authors use In-111 labeled water and Tc-99MSC (Sulfur Colloid) labeled scrambled eggs. For single phase studies either the liquid or solid phase material is used

    The coexistence of gastric cancer with duodenal ulcer has been found empirically to be rare, but why it is rare is difficult to explain satisfactorily. To elucidate this question, we carried out a literature review of the subject. The frequency with which the two diseases coexist is 0.1-1.7%, and the main factor associated with both gastric cancer and duodenal ulcer is Helicobacter pylori infection. However, there are marked differences between the disorders of hyperchlorhydria in duodenal ulcer, and hypochlorhydria in gastric cancer. The most acceptable view of the reason for the difference may be that the acquisition of H. pylori infection occurs mainly in childhood, so that the time of acquisition of atrophic gastritis may be the most important, and if atrophic gastritis is not acquired early, high levels of gastric acid may occur, and consequently acute antral gastritis and duodenal ulcer may occur in youth, whereas, in elderly individuals, persistent H. pylori infections and the early appearance of atrophic gastritis may be the causes of low gastric acid, and consequently gastric cancer may occur. In patients with duodenal ulcer, factors such as nonsteroidal anti-inflammatory drugs (NSAIDs) and dupA-H. pylori strains may contribute to preventing the early acquisition of atrophic gastritis, while acid-suppressive therapy and vascular endothelial growth factor and other entities may inhibit atrophic gastritis. In contrast, in gastric cancer, factors such as excessive salt intake, acid-suppressive therapy, polymorphisms of inflammatory cytokines, and the homB-H. pylori strain may contribute to the early acquisition of atrophic gastritis, while factors such as NSAIDs; fruits and vegetables; vitamins A, C, and E; and good nutrition may inhibit it.

    Invasive aspergillosis is an opportunistic infection that usually occurs in immunocompromised patients. Although there are a few rare reports of isolated invasive aspergillosis affecting the small intestine, isolated or disseminated gastric invasive aspergillosis is extremely rare. Herein, we report 2 cases of gastric invasive aspergillosis in a 72 year old woman and a 43 year old man; the woman had been recovering from ruptured left posterior communicating artery aneurysm, which presented as emphysematous gastritis and the man from acute subdural haemorrhage in the intensive care unit, which presented as a pseudoaneurysm on CT imaging.

    Forty two cases of gastric cancers were reviewed. The cancer had been examined by CT and was confirmed by operation and pathology. The diagnostic results of gastric cancers obtained by CT were compared with that from GI and fibro-gastroscopy examination. The results showed that the preparation of gastrointestinal tract before CT examination was important in the CT diagnosis of gastric cancer. CT in diagnosis of focus of gastric cancer and organ invasion is better than Gl and Fibro-gastroscopy and accuracy in diagnosis of gastric cancers is near to that of GI examination

    Smooth muscle tumors of stomach are unusual tumors, accounting for 1-3% of primary gastric malignancies. Diagnosis of these tumors is important because of the more favorable prognosis of this tumor than that of gastric carcinoma. A retrospective study was made in 18 patients who had pathology-proven gastric leiomyoma and leiomyosarcoma to identify radiologic characteristics for recent 6 years from Jan. 1978 to July. 1984 at Department of Radiology, Seoul National University Hospital. The results were as follows: 1. Age of 13 cases of gastric leiomyosarcoma ranged from 36 to 70 with average of 51 and the male to female ratio was 10 ; 3. Age of 5 cases of gastric leiomyoma ranged from 24 to 67 with average of 44 and the male to female ratio was 3 : 2. 2. Clinically, gastric leiomyosarcoma had epigastric pain in 7 cases, palpable mass in 4 cases, melena in 3 cases, haematemesis in 2 cases, 5 cases of gastric leiomyoma also had above symptoms respectively. 3. Of the 13 cases of gastric leiomyosarcoma studied by upper gastrointestinal examination, 6 cases (32%) involved the fundus, 10 cases (50%) in the body, 3 cases (18%) in the antrum. Of the 5 cases of gastric leiomyoma, 4 cases were confined to the fundus and 1 case in the body. 4. The size of the 13 gastric leiomyosarcoma ranged from 5 to more than 20 cm in diameter. The size of the 5 gastric leiomyomas ranged from 3 to 9 cm in diameter. 5. The growth type of gastric leiomysarcoma was exophytic in 8 cases, endogastric in 1 case and mixed pattern in 4 cases. The growth type of gastric leiomyoma were exophytic in 1 case, endogastric in 2 cases and mixed in 2 cases. 6. Mucosal pattern of gastric leiomyosarcoma were mainly effaced pattern in 10 cases (77%), but 3 cases (23%) showed irregular destruction. 1 case of gastric leiomyoma showed mucosal irregularity. 7. Ulceration was present in 10 cases of gastric leiomyosarcoma either single or multiple. 2 cases of gastric leiomyoma showed small ulcerations. Calciflation

  3. Scintigraphic evaluation of gastric emptying and motility

    The stomach consists of two functionally distinct parts. The fundus and upper corpus mainly serve as a reservoir and exert primarily a tonic activity, which presses ingesta towards the antrum and duodenum. The phasic contractility of the lower corpus and antrum cause mechanical breakdown and mixing of the food particels. A complex regulation of these mechanisms provides a regular gastric emptying. Various disorders such as diabetes mellitus, mixed connective tissue diseases, gastritis, tumors, dyspeptic disorders but also drugs and gastric surgery may influence or impair gastric function and may cause typical symptoms such as upper abdominal discomfort, bloating, nausea and vomiting. However, the interpretation of gastrointestinal symptoms often is difficult. Radionuclide studies of gastric emptying and motility are the most physiologic tools available for studying gastric motor function. Gastric scintigraphy is non-invasive, uses physiologic meal and is quantitative. Emptying curves generated from the gastric ROI offer information whether a disorder is accompanied by a regular, fast or slow gastric emptying. Data on gastric contractions (amplitude and frequency) provide additional information to results obtained by conventional emptying studies. Depending on the underlying disorder, gastric emptying and peristalsis showed both corresponding and discrepant findings. Therefore, both parameters should be routinely assessed to further improve characterisation of gastric dysfunction by scintigraphy. (orig.) [de

    At present, biopsy specimens, cancer cell lines and tissues obtained by gastric surgery are used in the study and analysis of gastric cancer, including the molecular mechanisms and proteomics. However, fibroblasts and other tissue components may interfere with these techniques. Therefore, the present study aimed to develop a procedure for the isolation of viable human gastric epithelial cells from gastric surgical tissues. A method was developed to culture human gastric epithelial cells using fresh, surgically excised tissues and was evaluated using immunocytochemistry, periodic acid-Schiff (PAS) staining and cell viability assays. Low cell growth was observed surrounding the gastric tissue on the seventh day of tissue explant culture. Cell growth subsequently increased, and at 12 days post-explant a high number of pure epithelial cells were detected. The gastric cancer cells exhibited rapid growth with a doubling time of 13-52 h, as compared to normal cells, which had a doubling time of 20-53 h. Immunocytochemical analyses of primary gastric cells revealed positive staining for cytokeratin 18 and 19, which indicated that the culture was comprised of pure epithelial cells and contained no fibroblasts. Furthermore, PAS staining demonstrated that the cultured gastric cells produced neutral mucin. Granulin and carbohydrate antigen 724 staining confirmed the purity of gastric cancer and normal cells in culture. This method of cell culture indicated that the gastric cells in primary culture consisted of mucin-secreting gastric epithelial cells, which may be useful for the study of gastric infection with Helicobacter pylori and gastric cancer.

  5. Localization of ectopic gastric mucosa by scintigraphy

    1988-01-01

    When gastric mucosal tissue occurs outside of the confines of the stomach, it is termed ectopic or heterotopic. Ectopic gastric mucosa may be found within Meckel's diverticulum, duplications of the alimentary tract, and Barrett's esophagus. In addition, a surgeon may inadvertently leave behind antral gastric mucosa while performing a partial gastrectomy for peptic ulcer disease (i.e., retained gastric antrum). It is important to detect the presence and location of ectopic mucosa because acid and pepsin secretion may cause ulceration in the adjacent tissue resulting in serious complications. The only currently available specific diagnostic technique for detecting ectopic gastric mucosa is pertechnetate Tc 99m (TcO 4- ) scintigraphy. This chapter reviews the functional anatomy of gastric mucosa, the mechanism of TcO 4 - localization, the various entities containing ectopic gastric mucosa, and the methods and results of TcO 4 - scanning for these disorders

    European experience in endoscopic mucosal resection (EMR) for early gastric cancer is still relatively low, since early stomach cancer is diagnosed at a much lower rate in Europe than in Japan and generally operable patients are referred to surgery for radical resection. Endoscopic mucosal resection or mucosectomy was developed as a promising technology to diagnose and treat mucosal lesions in the esophagus, stomach and colon. In contrast to surgical resection, EMR allows "early cancers" to be removed with a minimal cost, morbidity and mortality. We present the case of a patient with hepatic cirrhosis incidentally diagnosed with an elevated-type IIa early gastric cancer. Echoendoscopy was performed in order to assess the depth of invasion into the gastric wall confirming the only mucosal involvement. We performed an EMR using "cup and suction" method. After the procedure, the patient experienced an acute upper gastrointestinal bleeding from the ulcer bed requiring argon plasma coagulation. The histopathological examination confirmed an early cancer, without involvement of muscularis mucosae. The patient has had an uneventful evolution being well at six months after the procedure

    Clinical results of intraoperative radiotherapy for gastric cancer were reported. One hundred and five cases of gastric cancer were treated by intraoperative radiotherapy. Whatever the stage of the patient was, 3-year survival rate was found to be better in the radiotherapy group than that of the control group (treated surgical resection only). Five year survival rate of the stages III and IV in the radiotherapy group was better than the control group. Unfavorable side effects were observed in 4 cases out of 105 cases. In one case, penetration of postoperative peptic ulcer into the irradiated aortic wall was found by autopsy. Two cases of bile duct stenosis and one case of ileus due to acutely developed peritonitis carcinomatosa were experienced. In conclusion, intraoperative radiotherapy immediately after surgical resection for the treatment of gastric cancer was found to be an effective method. The most effective application of the method appears to be to cases of stage II and III without liver metastasis and peritoneal disseminations (H/sub 0/P/sub 0/, M, A).

    In recent 5 years, we have experienced 24 cases of advanced gastric cancer associated with obstructive uropathy. Included were 19 cases of undifferentiated, 3 cases of differentiated and 2 cases of unknown histological type. Obstructive uropathy is diagnosed based on the typical radiological findings such as dilatation and delayed demonstration of the upper collecting systems. Pathologically, undifferentiated type of gastric cancer had tendency to spread infiltratively along the vessels, nerves and the lymphatics without alteration of the ordinary anatomical structures. In such cases, mucosal surface of the urinary tract tended to be spared in spite of extensive tumor invasion. It was proven that several radiological findings were characteristic of urinary tract involvement secondary to gastric cancer. Either thread-like ureteral stricture by IVU or ring-like appearance of the ureter by CT is one of those typical findings. Renal sinus involvement may occur continuously to diffuse retroperitoneal invasion and it appears as a thickened wall of renal pelvis or soft tissue mass directly extending into the fatty tissue of renal sinus by CT. In such cases IVU has less diagnostic ability because of the lack of mucosal destruction. If the urinary bladder is involved, it typically shows chestnut-bur appearance by IVU and diffuse wall thickening by CT. In cases of advanced gastric cancer, particularly in cases of histologically undifferentiated type, CT and IVU images should be carefully interpreted in consideration of the infiltrative part of tumor extention.

    The freeze-dried aqueous extract (AE) from the aerial parts of Scoparia dulcis was tested for its effects on experimental gastric hypersecretion and ulcer in rodents. Administration of AE to animals with 4h pylorus ligature potently reduced the gastric secretion with ED(50)s of 195 mg/kg (rats) and 306 mg/kg (mice). The AE also inhibited the histamine- or bethanechol-stimulated gastric secretion in pylorus-ligated mice with similar potency suggesting inhibition of the proton pump. Bio-guided purification of the AE yielded a flavonoid-rich fraction (BuF), with a specific activity 4-8 times higher than the AE in the pylorus ligature model. BuF also inhibited the hydrolysis of ATP by H(+),K(+)-ATPase with an IC(50) of 500 microg/ml, indicating that the inhibition of gastric acid secretion of Scoparia dulcis is related to the inhibition of the proton pump. Furthermore, the AE inhibited the establishment of acute gastric lesions induced in rats by indomethacin (ED(50)=313 mg/kg, p.o.) and ethanol (ED(50)=490 mg/kg, p.o.). No influence of the AE on gastrointestinal transit allowed discarding a possible CNS or a cholinergic interaction in the inhibition of gastric secretion by the AE. Collectively, the present data pharmacologically validates the popular use of Scoparia dulcis in gastric disturbances.

    Early neonatal sepsis is often due to intra-amniotic infection. The stomach of the neonate contains fluid swallowed before and during delivery. The presence of bacteria as well as neutrophils detected by culture or Gram stain of the gastric fluid during the first day of life is suggestive of exposure to bacteria or inflammation. We undertook this study to determine the relationship between gastric fluid analysis and amniotic fluid obtained by transabdominal amniocentesis in the detection of Ureaplasma species, the most frequent microorganisms responsible for intra-amniotic infection. The study population consisted of 100 singleton pregnant women who delivered preterm neonates (Ureaplasma species was performed. Intra-amniotic inflammation was defined as an elevated amniotic fluid matrix metalloproteinase-8 concentration (>23 ng/mL). (1) Ureaplasma species were detected by culture or PCR in 18% (18/100) of amniotic fluid samples and in 5% (5/100) of gastric fluid samples; (2) among the amniotic fluid cases positive for Ureaplasma species, these microorganisms were identified in 27.8% (5/18) of gastric fluid samples; (3) none of the cases negative for Ureaplasma species in the amniotic fluid were found to be positive for these microorganisms in the gastric fluid; (4) patients with amniotic fluid positive for Ureaplasma species but with gastric fluid negative for these microorganisms had a significantly higher rate of intra-amniotic inflammation, acute histologic chorioamnionitis, and neonatal death than those with both amniotic fluid and gastric fluid negative for Ureaplasma species; and (5) no significant differences were observed in the rate of intra-amniotic inflammation, acute histologic chorioamnionitis, and neonatal death between patients with amniotic fluid positive for Ureaplasma species but with gastric fluid negative for these microorganisms and those with both amniotic fluid and gastric fluid positive for Ureaplasma species.

    A 10-year-old male red panda presented acutely with symptoms of shock due to acute abdominal distress and respiratory compromise. Abdominal ultrasound confirmed a severely distended stomach for which passage of an orogastric tube for relief was unsuccessful. Intra-operatively, the stomach was found to be distended and torsed around its long axis supporting the diagnosis of Gastric dilitation-volvulus (GDV). The animal arrested and died intra-operatively and was submitted for necropsy with lesions supportive of the diagnosis of GDV. No risk factors for GDV were found to correlate between the panda and those described in domestic dogs. This case suggests that red pandas can be susceptible to this condition in captive settings.

    Gastromalacia is the acute autolytic erosion of the gastric wall. It generally occurs postmortem, and it appears as a slimy brownish black region of the wall which occurs principally in the gastric fundus. A 59-year-old woman died in the Emergency Department following a 2-day period of mild abdominal pain, vomiting, and diarrhea. A forensic autopsy was performed which revealed a rupture of the gastric fundus that had caused leakage of gastric content into the abdominal cavity. There was no macroscopic evidence of peritonitis, and the stomach wall adjacent to the rupture site showed marked thinning. The gross appearance was typical of gastromalacia. In contrast, histological observations revealed the presence of an ulcer at the site of perforation and a severe acute inflammatory reaction indicating a robust reaction with an antemortem rupture. © 2014 American Academy of Forensic Sciences.

    Full Text Available Duodenal obstruction due to duodenal atresia occurs in 1 in 10,000 live births and is the most common type of intestinal obstruction in neonates [1–3]. Gastric outlet obstruction in the newborn period from causes other than hypertrophic pyloric stenosis is very uncommon [3]. Potential etiologies include gastric volvulus, antral web, and duplication cysts. Gastric diverticula in the infant is even more rare, with only a few case reports published, and only one describes a gastric diverticulum in the presence of a duodenal atresia [4–8]. In this report, we describe the first case of a gastric outlet obstruction due to a gastric diverticulum in the presence of duodenal atresia.

    Full Text Available Abstract Background Gastric ileus is an unsolved clinical problem and current treatment is limited to supportive measures. Models of ileus using anesthetized animals, muscle strips or isolated smooth muscle cells do not adequately reproduce the clinical situation. Thus, previous studies using these techniques have not led to a clear understanding of the pathophysiology of ileus. The feasibility of using food intake and fecal output as simple, clinically relevant endpoints for monitoring ileus in a conscious mouse model was evaluated by assessing the severity and time course of various insults known to cause ileus. Methods Delayed food intake and fecal output associated with ileus was monitored after intraperitoneal injection of endotoxin, laparotomy with bowel manipulation, thermal injury or cerulein induced acute pancreatitis. The correlation of decreased food intake after endotoxin injection with gastric ileus was validated by measuring gastric emptying. The effect of endotoxin on general activity level and feeding behavior was also determined. Small bowel transit was measured using a phenol red marker. Results Each insult resulted in a transient and comparable decrease in food intake and fecal output consistent with the clinical picture of ileus. The endpoints were highly sensitive to small changes in low doses of endotoxin, the extent of bowel manipulation, and cerulein dose. The delay in food intake directly correlated with delayed gastric emptying. Changes in general activity and feeding behavior were insufficient to explain decreased food intake. Intestinal transit remained unchanged at the times measured. Conclusion Food intake and fecal output are sensitive markers of gastric dysfunction in four experimental models of ileus. In the mouse, delayed gastric emptying appears to be the major cause of the anorexic effect associated with ileus. Gastric dysfunction is more important than small bowel dysfunction in this model.

    The paper shows the potentialities of gastric study by magnetic resonance imaging (MRI). The methodic aspects of gastric study have been worked out. The MRI-semiotics of the unchanged and tumor-affected wall of the stomach and techniques in examining patients with gastric cancer of various sites are described. Using the developed procedure, MRI was performed in 199 patients, including 154 patients with gastric pathology and 45 control individuals who had no altered gastric wall. Great emphasis is placed on the role of MRI in the diagnosis of endophytic (diffuse) gastric cancer that is of priority value in its morphological structure. MRI was found to play a role in the diagnosis of the spread of a tumorous process both along the walls of the stomach and to its adjacent anatomic structures.

    Gastric and esophageal emptying were evaluated in 31 obese patients and 31 control subjects. A double-isotope techniques was used to measure gastric emptying of a mixed solid/liquid meal, and esophageal emptying was measured as the time taken for a bolus of the solid meal to enter the stomach. Gastric emptying of the solid and the liquid meal and esophageal emptying were delayed in the obese patients compared with the control subjects. There were no significant relationships among gastric emptying, esophageal emptying, and upper gastrointestinal symptoms in the obese patients alone. However, in the total group of 62 subjects there were significant correlations between body mass index and both gastric and esophageal emptying. These results indicate that delayed gastric and esophageal emptying occurs frequently in obesity and that these abnormalties relate to body weight.

    Actinodaphne sesquipedalis Hook. F. Var. Glabra (Kochummen), also known as “Medang payung” by the Malay people, belongs to the Lauraceae family. In this study, methanol leaf extract of A. sesquipedalis was investigated for their acute toxicity and gastroprotective effects to reduce ulcers in rat stomachs induced by ethanol. The rats were assigned to one of five groups: normal group (group 1), ulcer group (group 2), control positive drug group (group 3) and two experimental groups treated with 150 mg/kg (group 4) and 300 mg/kg (group 5) of leaf extract. The rats were sacrificed an hour after pretreatment with extracts, and their stomach homogenates and tissues were collected for further evaluation. Macroscopic and histological analyses showed that gastric ulcers in rats pretreated with the extract were significantly reduced to an extent that it allowed leukocytes penetration of the gastric walls compared with the ulcer group. In addition, an ulcer inhibition rate of >70% was detected in rats treated with both doses of A. sesquipedalis extract, showing a notable protection of gastric layer. Severe destruction of gastric mucosa was prevented with a high production of mucus and pH gastric contents in both omeprazole-treated and extract-treated groups. Meanwhile, an increase in glycoprotein uptake was observed in pretreated rats through accumulation of magenta color in Periodic Acid Schiff staining assay. Analysis of gastric homogenate from pretreated rats showed a reduction of malondialdehyde and elevation of nitric oxide, glutathione, prostaglandin E2, superoxide dismutase and protein concentration levels in comparison with group 2. Suppression of apoptosis in gastric tissues by upregulation of Hsp70 protein and downregulation of Bax protein was also observed in rats pretreated with extract.

    Gastric perforation is a life-threatening condition, requiring early and reliable discovery. The delay before surgical treatment is a strong determinant of poor outcome, associated complications and hospitalization costs. By using ultrasound and multi-detector computed tomography (MDCT) we can further evaluate undiagnosed cases of silent gastric perforations presenting with non-specific acute abdomen. Here we bring forth the role of a radiologist in cases of perforation which present with indirect signs involving the organs forming the stomach bed, like the spleen, pancreas and kidney. A 25-year-old male patient presented with an acute onset of severe upper abdominal pain radiating to the back and vomiting. MDCT of the abdomen was done which revealed atrophic pancreas with organized collection in the sub-capsular location indenting the superior pole of the left kidney. Spleen was not visualized. The most striking imaging finding in that case was destruction of the splenic parenchyma with protrusion of the remaining tissue into the stomach lumen. The hypothesis behind this was a cascade of events which started with gastric perforation, spillage of highly destructive gastric juice over the stomach bed and finally becoming silent with rapid sealing of the defect by the omentum and the spleen. Acute abdomen is a diagnostic challenge to a clinician and radiologist with gastric perforation being a great mimicker of other urgent abdominal pathologies. To avoid a delayed diagnosis or a misdiagnosis, familiarity with typical and atypical imaging features is essential as in our case of splenic lysis. It acted as the 2 nd policeman and provided a great clue to solve the diagnostic dilemma

    Full Text Available Abstract Background With an incidence of less than 5%, type II paraesophageal hernias are one of the less common types of hiatal hernias. We report a case of a perforated prepyloric gastric ulcer which, due to a type II hiatus hernia, drained into the mediastinum. Case presentation A 61-year old Caucasian man presented with acute abdominal pain. On a conventional x-ray of the chest a large mediastinal air-fluid collection and free intra-abdominal air was seen. Additional computed tomography revealed a large intra-thoracic air-fluid collection with a type II paraesophageal hernia. An emergency upper midline laparotomy was performed and a perforated pre-pyloric gastric ulcer was treated with an omental patch repair. The patient fully recovered after 10 days and continues to do well. Conclusion Type II paraesophageal hernia is an uncommon diagnosis. The main risk is gastric volvulus and possible gastric torsion. Intrathoracic perforation of gastric ulcers due to a type II hiatus hernia is extremely rare and can be a diagnostic and treatment challenge.

    Equine gastric ulcer syndrome is one of the most frequently reported diseases in thoroughbred racehorses. Although several risk factors for the development of gastric ulcers have been widely studied, investigation of microbiological factors has been limited. In this study, the presence of Helicobacter spp. and the gastric microbial communities of thoroughbred racehorses having mild to severe gastric ulcers were investigated. Although Helicobacter spp. were not detected using culture and PCR techniques from 52 gastric biopsies and 52 fecal samples, the genomic sequences of H. pylori and H. ganmani were detected using nextgeneration sequencing techniques from 2 out of 10 representative gastric samples. The gastric microbiota of horses was mainly composed of Firmicutes (50.0%), Proteobacteria (18.7%), Bacteroidetes (14.4%), and Actinobacteria (9.7%), but the proportion of each phylum varied among samples. There was no major difference in microbial composition among samples having mild to severe gastric ulcers. Using phylogenetic analysis, three distinct clusters were observed, and one cluster differed from the other two clusters in the frequency of feeding, amount of water consumption, and type of bedding. To the best of our knowledge, this is the first study to investigate the gastric microbiota of thoroughbred racehorses having gastric ulcer and to evaluate the microbial diversity in relation to the severity of gastric ulcer and management factors. This study is important for further exploration of the gastric microbiota in racehorses and is ultimately applicable to improving animal and human health.

    2016-01-01

    Gut hormone secretion in response to nutrient ingestion appears to depend on membrane proteins expressed by the enteroendocrine cells. These include transporters (glucose and amino acid transporters), and, in this case, hormone secretion depends on metabolic and electrophysiological events elicited...... that determines hormone responses. It follows that operations that change intestinal exposure to and absorption of nutrients, such as gastric bypass operations, also change hormone secretion. This results in exaggerated increases in the secretion of particularly the distal small intestinal hormones, GLP-1, GLP-2......, oxyntomodulin, neurotensin and peptide YY (PYY). However, some proximal hormones also show changes probably reflecting that the distribution of these hormones is not restricted to the bypassed segments of the gut. Thus, cholecystokinin responses are increased, whereas gastric inhibitory polypeptide responses...

    1988-01-01

    Adenocarcinoma of the stomach is a moderately radioresponsive neoplasm. Attempts to treat patients with unresectable disease with external beam radiation therapy alone have generally failed because of problems with tumor localization and adequate dose delivery as well as the inherent radioresponsiveness of the gastric mucosa and the organs intimately related to the stomach. Combining external beam therapy and chemotherapy (acting as a systemic agent and as a radiosensitizer) seems to be of some (albeit limited) benefit in the management of unresectable adenocarcinoma of the stomach. Optimum combinations of radiation therapy, chemotherapy, and radiation sensitizers in this situation remain to be determined. The authors discuss strides which have been made in the treatment of gastric cancer. They also address the unanswered clinical questions which remain regarding the use of radiation therapy in the treatment of this highly lethal disease

The tumor responded markedly to radiation in 37% of 92 cases, irradiated more than 5000 rad and regressed completely in only 5% of them. Out of them, the permanent cure was achieved in 3% of T2-4 M0 cases. Serious complications, such as hemorrhagic gastritis, massive bleeding, chronic ulcer of the stomach and perforation, were also observed in a few per cent of them. It was suggested that in the treatment of inoperable gastric cancer, the combination treatment of radiation and chemotherapy should be chosen as a valuable therapeutic procedure to get a good palliation.

    Full Text Available An eight year old female dog was referred with anorexia, nervousness and emaciation. At the point of time, severe lifelessness was the only symptom. Then euthanasia was done according to the owner’s decision. As a result of postmortem examination, thin white matters were found on the gastric mucosa of the greater curvature and there were no other significant gross findings. Tissue specimens were collected from the gastric wall, esophagus, gall bladder, aorta, heart, kidneys, liver, mesenteric lymph node, lungs, urinary bladder and spleen and processed for histopathology. Microscopically, the masses of stomach were consisted of well-differentiated osteoid tissues, the compact bone-osteocytes and the matured lamellated bone with Haversian system. It was diagnosed as osteoma of the stomach. Other organs were free on such histological findings.

    Full Text Available In the present study, the ethanolic root extract of Desmodium gangeticum (L. DC., Fabaceae, (EDG, have been studied in various acute and chronic ulcer mouse models. Oral administration of root extract, significantly decrease the ulcer index and lesion number in a dose dependent manner against ethanol induced acute gastric ulcer in mice. In gastric ulcerated animal that received high dose of 150 mg/kg EDG, the mucosa showed no ulceration with slight focal congestion and the glands appeared normal. Pylorus ligated mice, pretreated with EDG showed significant decrease in ulcerous activity under chronic condition. The highest dose (150 mg/kg of the extract provoked a marked increase in protein and glutathione levels, when compare to control. Furthermore, gastric juice, free acidity and total acid output were inhibited in a dose-dependent manner at p<0.05 level. Our results indicate that the EDG possess gastroprotective activity and increasing regeneration of damaged gastric mucosa and thus safe for human use.

    Full Text Available The acute toxicity, the antioxidant activity, and the pharmacological activity on the gastrointestinal tract of rodents of the ethanolic extract (TFEE from the bark of Terminalia fagifolia Mart. & Zucc. (Combretaceae and of its aqueous (TFAqF, hydroalcoholic (TFHAF, and hexanic (TFHEXF partition fractions have been evaluated. TFEE presented low acute toxicity, antioxidant, and antiulcerogenic activity against ethanol-induced ulcers, which was partially blocked by pretreatment with L-NAME and indomethacin. It reduced the total acidity and raised the pH of gastric secretion. Additionally, TFEE delayed gastric emptying and slightly inhibited the small intestinal transit and also presented a weakly antidiarrheal activity. The antiulcerogenic and antioxidant activity were also detected in TFAqF and TFHAF but not in TFHEXF. The antisecretory and gastroprotective activity of TFEE partially involve the nitric oxide and prostaglandin participation. Nevertheless, TFEE, TFAqF, and TFHAF drastically reduced the mucus layer adhered to the gastric wall of rats treated with ethanol or indomethacin. Complementary studies are required in order to clarify the paradox of the presence of a gastroprotector activity in this plant that, at the same time, reduces the mucus layer adhered to the gastric wall.

    Full Text Available This study aimed to determine the frequency of gastric pathologies in donkeys (Equus africanus asinus in the department of Córdoba, Colombia. Stomachs of 137 donkeys (73 intact males, 16 castrated males, and 48 females, aged between 1 to 25 years, were examined, characterized and photographed post mortem. Data on sex, age and pathology were reported on the respective forms and then digitized. Of the total population (137 donkeys, stomach ulcers and associated gastritis were found in 100% of the samples, antral edema in 56.9%, parasites (Trichostrongylus axei in 10.2%, and impaction in 5.8%. Furthermore, Hemomelasma gastric was found in one stomach (0.7%. As a conclusion, 100% of the evaluated animals presented at least some kind of gastric pathology. Acute gastritis was the most frequent type (71.5%, followed in a smaller proportion by chronic gastritis (28.4%. The study showed a significant statistical dependence between age and the degree of injury to the glandular mucosa (p < 0.05. Thus, it evidenced a high incidence of gastric pathologies in donkeys in different livestock holdings in Córdoba, among which squamous ulcers are the most frequent ones, followed by acute gastritis and antral edema. For this reason, it is necessary to do more research and to raise awareness about the treatment of these pathologies in these animals.

    Although the idea that gastric problems are in some way related to mental activity dates back to the beginning of the last century, until now it has received scant attention by physiologists, general practitioners and gastroenterologists. The major breakthrough in understanding the interactions between the central nervous system and the gut was the discovery of the enteric nervous system (ENS) in the 19th century. ENS (also called 'little brain') plays a crucial role in the regulation of the physiological gut functions. Furthermore, the identification of corticotropin-releasing factor (CRF) and the development of specific CRF receptor antagonists have permitted to characterize the neurochemical basis of the stress response. The neurobiological response to stress in mammals involves three key mechanisms: (1) stress is perceived and processed by higher brain centers; (2) the brain mounts a neuroendocrine response by way of the hypothalamic-pituitary-adrenal axis (HPA) and the autonomic nervous system (ANS), and (3) the brain triggers feedback mechanisms by HPA and ANS stimulation to restore homeostasis. Various stressors such as anger, fear, painful stimuli, as well as life or social learning experiences affect both the individual's physiologic and gastric function, revealing a two-way interaction between brain and stomach. There is overwhelming experimental and clinical evidence that stress influences gastric function, thereby outlining the pathogenesis of gastric diseases such as functional dyspepsia, gastroesophageal reflux disease and peptic ulcer disease. A better understanding of the role of pathological stressors in the modulation of disease activity may have important pathogenetic and therapeutic implications. © 2014 S. Karger AG, Basel.

    To investigate whether interdigestive gastric acid secretion can be controlled by a possible memory-related cortical mechanism. To evaluate gastric secretion in rats, we used a methodology that allows gastric juice collection in rats in their habitual conditions (without any restraining) by pairing sound as the conditioning stimulus (CS) and food as the unconditioning stimulus (US). The levels of gastric acid secretion under basal conditions and under sound stimulation were recorded and the circulating gastrin levels determined. When the gastric juice was collected in the course of the conditioning procedure, the results showed that under noise stimulation a significant increase in gastric acid secretion occurred after 10 days of conditioning (p<0.01). The significance was definitively demonstrated after 13 days of conditioning (p<0.001). Basal secretions of the conditioned rats reached a significant level after 16 days of conditioning. The levels of noise-stimulated gastric acid secretion were the highest so far described in physiological experiments carried out in rats and there were no significant increases in the circulating gastrin levels. The results point to the important role played by cortical structures in the control of interdigestive gastric acid secretion in rats. If this mechanism is also present in humans, it may be involved in diseases caused by inappropriate gastric acid secretion during the interprandial periods.

    Gastric cancer is one of the most common malignant tumors in digestive tract functional MRI can represent the functional changes of the tumor. DWI not only provides a new way to diagnosis the gastric cancer, but also reflect the pathology changes of the tumor, which has great value to predict the therapeutic effect and prognosis of the tumor. MRS is the only method to test the chemical composition of tissues in live without injury, which has great value in the early diagnosis of gastric tumor and in the research of tumor mechanism. This review is mainly focused on the status and development of functional MRI in gastric cancer. (authors)

    Gastric emptying scintigraphy was introduced more than 25 years ago by Grittith and still remains the gold standard to assess gastric emptying. Test meals, radiopharmaceuticals and acquisition procedures have been refined and optimized over the years and the test procedure is now pretty well standardized. However, in its most common use, gastric emptying scintigraphy provides little information on gastric physiology. Over the last decade, modelling of the liquid and solid emptying curves have brought some insight in the complex gastric physiology. Compartmental analysis of the stomach has also provided information on the pathophysiological mechanisms of delayed gastric emptying. Over the past 5 years, the most dramatic development in gastric emptying scintigraphy has been the introduction of Digital Antral Scintigraphy (DAS). Digital Antral scintigraphy basically consists in dynamically imaging of the stomach and the use of a refined Fourier transform processing method. This new procedure allows for the visualization of antral contractions and, alike manometry, permits quantitative characterization on the frequency and amplitude of these contractions. Overall, this new procedure provides a unique, non invasive tool to characterize gastric motility, to define the pathophysiologic mechanisms of gastric motor disorders and to evaluate the effect of new gastro-kinetic compounds.

    Objective: Gastric blunt traumatic injuries are uncommon and their radiological appearance has been infrequently reported in medical literature. These injuries are difficult to diagnose preoperatively, though they require immediate recognition to minimize their otherwise high mortality and morbidity. The aim of our study is to describe the radiological appearance of blunt gastric traumatic injuries. Materials and methods: Retrospective evaluation of a 25 patients series observed between January 1997 and May 2005. Results: We observed rupture of the stomach in 20% of cases, in 44% of cases a partial lesion of the stomach, in one case a necrotic post-traumatic volvulus, five patients (20%) had benign portal pneumatosis, in three patients the stomach was secondarily involved because of a diaphragmatic hernia. The fundus resulted to be the most frequently damaged part of the stomach (80%). Conclusions: Blunt traumatic injuries need a careful and systematic approach given their economical and social relevance. For these reasons uncommon lesions require attention and may be important to search for specific findings of gastric lesions

    Obesity is a public health problem, for which the prevalence has increased worldwide at an alarming rate, affecting 1.7 billion people in the world. To describe the technique employed in incomplete penetration of gastric band where endoscopic management and/or primary closure is not feasible. Laparoscopic removal of gastric band was performed in five patients with incomplete penetrance using Foley catheterization in the perforation site that could lead to the development of a gastro-cutaneous fistula. The cases presented include a leak that required surgical lavage with satisfactory outcome, and one patient developed stenosis 3 years after surgical management, which was resolved endoscopically. In all cases, the penetration site closed spontaneously. Gastric band erosion has been reported in 3.4% of cases. The reason for inserting a catheter is to create a controlled gastro-cutaneous fistula, allowing spontaneous closure. Various techniques have been described: the totally endoscopic, hybrid techniques (endoscopic/laparoscopic) and completely laparoscopic. A technique is described here that is useful and successful in cases where the above-described treatments are not viable. Copyright © 2015. Published by Masson Doyma México S.A.

    A brachycephalic dog was presented with an acute onset of retching and abdominal discomfort. The dog had a chronic history of stertor and exercise intolerance suggestive of brachycephalic airway obstructive syndrome. Radiographs were consistent with a Type II hiatal hernia. The dog was referred and within hours of admission became acutely painful and developed tympanic abdominal distension. A right lateral abdominal radiograph confirmed gastric dilatation and volvulus with herniation of the pylorus through the hiatus. An emergency exploratory coeliotomy was performed, during which the stomach was derotated, and an incisional gastropexy, herniorrhaphy and splenectomy were performed. A staphylectomy was performed immediately following the exploratory coeliotomy. The dog recovered uneventfully. Gastric dilatation and volvulus is a potentially life-threatening complication that can occur in dogs with Type II hiatal hernia and should be considered a surgical emergency. © 2014 British Small Animal Veterinary Association.

    Perforated marginal ulcer (PMU) after laparoscopic Roux-en-Y gastric bypass (LRYGB) is a serious complication, but its incidence and etiology have rarely been investigated. Therefore, a retrospective review of all patients undergoing LRYGB at the authors' center was conducted to determine the incidence of PMU and whether any causative factors were present. A prospectively kept database of all patients at the authors' bariatric center was retrospectively reviewed. The complete records of patients with a PMU were examined individually for accuracy and analyzed for treatment, outcome, and possible underlying causes of the marginal perforation. Between April 1999 and August 2007, 1% of the patients (35/3,430) undergoing laparoscopic gastric bypass experienced one or more perforated marginal ulcers 3 to 70 months (median, 18 months) after LRYGB. The patients with and without perforation were not significantly different in terms of mean age (37 vs 41 years), weight (286 vs 287 lb), body mass index (BMI) (46 vs 47), or female gender (89% vs 83%). Of the patients with perforations, 2 (6%) were taking steroids, 10 (29%) were receiving nonsteroidal antiinflammatory drugs (NSAIDs) at the time of the perforation, 18 (51%) were actively smoking, and 6 of the smokers also were taking NSAIDs. Eleven of the patients (31%) who perforated did not have at least one of these possible risk factors, but 4 (36%) of the 11 patients in this group had been treated after bypass for a marginal ulcer. Only 7 (20%) of the 35 patients who had laparoscopic bypass, or 7 (0.2%) in the entire group of 3,430 patients, perforated without any warning. There were no deaths, but three patients reperforated. The incidence of a marginal ulcer perforating after LRYGB was significant (>1%) and appeared to be related to smoking or the use of NSAIDs or steroids. Because only 0.2% of all patients acutely perforated without some risk factor or warning, long-term ulcer prophylaxis or treatment may be necessary

    An 8-year-old crossbreed dog presented after one episode of acute collapse due to rupture of a splenic haemangiosarcoma. Following splenectomy the dog recovered well. Two days after discharge the dog re-presented because of gastric dilatation-volvulus (GDV) that eventually led to his death. Splenectomy to remove a voluminous splenic tumour may predispose to GDV and dogs may benefit from concurrent prophylactic gastropexy.

  18. The role of gastric scintigraphy in primary or post surgical disorders of gastric emptying

    1996-01-01

    Gastric scintigraphy is the gold standard for the measurement of the gastric emptying of a meal because of its reliability and its reproducibility and the respect of physiological conditions. Moreover, this technique allows to measure the emptying of solid and liquid phases simultaneously. Symptoms motivating a gastric scintigraphy, suggest either a gastric stasis (dyspepsia) or a gastric incontinence (dumping syndrome). The two most frequent clinical conditions triggering this test are motility disorders following vagotomy, a delayed emptying of solids is often associated to an accelerated emptying of liquids. Gastric scintigraphy proves quite useful in these conditions, since the diagnosis of such complex abnormalities is uneasy to establish exclusively on a clinical basis. In idiopathic dyspepsia, gastric stasis is proved only in 50 % of the patients. However, a radionuclide study of gastric emptying is seldom ordered because of the common character and good tolerance of these symptoms. In everyday practice, gastric scintigraphy is considered only when gastric or intestinal obstructive lesions have been ruled out. A suggestive clinical picture and/or absence of a deteriorated general condition allow to prescribe a symptomatic treatment. More rarely, equivocal symptoms, degradation of the general condition and unresponsiveness to symptomatic drugs call for gastric scintigraphy. (authors). 241 refs., 2 figs

    To assess gastric trocarization and orogastric tubing as a means of gastric decompression for the initial management of gastric dilatation-volvulus. Retrospective review of 116 gastric dilatation-volvulus cases from June 2001 to October 2009. Decompression was performed via orogastric tubing in 31 dogs, gastric trocarization in 39 dogs and a combination of both in 46 dogs. Tubing was successful in 59 (75·5%) dogs and unsuccessful in 18 (23·4%) dogs. Trocarization was successful in 73 (86%) dogs and unsuccessful in 12 (14%) dogs. No evidence of gastric perforation was noted at surgery in dogs undergoing either technique. One dog that underwent trocarization had a splenic laceration identified at surgery that did not require treatment. Oesophageal rupture or aspiration pneumonia was not identified in any dog during hospitalization. No statistical difference was found between the method of gastric decompression and gastric compromise requiring surgical intervention or survival to discharge. Orogastric tubing and gastric trocarization are associated with low complication and high success rates. Either technique is an acceptable method for gastric decompression in dogs with gastric dilatation-volvulus. © 2013 British Small Animal Veterinary Association.

    Gastric adenomyoma is a rare tumour-like lesion composed of glandular components and smooth muscle bundles. We report a case of gastric adenomyoma in a 1-week-old neonate who presented with gastric outlet obstruction. To the best of our knowledge, this is the youngest child reported with gastric adenomyoma and a unique case demonstrating radiological findings of gastric adenomyoma in a young infant. At US, the lesion was seen as an asymmetrical mass-like wall-thickening of the pylorus. Upper gastrointestinal series showed findings similar to those seen in a case of hypertrophic pyloric stenosis. We suggest that gastric adenomyoma should be included in the causes of gastric outlet obstruction in neonates even though it is rare in young children.

    Full Text Available BACKGROUND: Anisakiasis is a parasitic disease caused primarily by Anisakis spp. larvae in Asia and in Western countries. The aim of this study was to investigate the genotype of Anisakis larvae endoscopically removed from Middle Eastern Japanese patients and to determine whether mucosal atrophy affects the risk of penetration in gastric anisakiasis. METHODS: In this study, 57 larvae collected from 44 patients with anisakiasis (42 gastric and 2 colonic anisakiasis were analyzed retrospectively. Genotyping was confirmed by restriction fragment length polymorphism (RFLP analysis of ITS regions and by sequencing the mitochondrial small subunit (SSU region. In the cases of gastric anisakiasis, correlation analyses were conducted between the frequency of larval penetration in normal/atrophic area and the manifestation of clinical symptoms. RESULTS: Nearly all larvae were A. simplex seusu stricto (s.s. (99%, and one larva displayed a hybrid genotype. The A. simplex larvae penetrated normal mucosa more frequently than atrophic area (p = 0.005. Finally, patients with normal mucosa infection were more likely to exhibit clinical symptoms than those with atrophic mucosa infection (odds ratio, 6.96; 95% confidence interval, 1.52-31.8. CONCLUSIONS: In Japan, A. simplex s.s. is the main etiological agent of human anisakiasis and tends to penetrate normal gastric mucosa. Careful endoscopic examination of normal gastric mucosa, particularly in the greater curvature of the stomach will improve the detection of Anisakis larvae.

Oral bioavailability of P2026 was estimated from plasma concentration of diclofenac and nitrate/nitrite (NOx). Anti-inflammatory activity was evaluated in three different models of inflammation: acute (carrageenan-induced paw oedema), chronic (adjuvant-induced arthritis), and systemic (lipopolysaccharide-induced endotoxic shock). Gastric tolerability was evaluated from compound's propensity to cause gastric ulcers. P2026 exhibited dose-dependent diclofenac and NOx release. Similar to diclofenac, P2026 showed potent anti-inflammatory activity in acute and chronic model, whereas it improved activity in systemic model. Both diclofenac and P2026 inhibited gastric prostaglandin, but only diclofenac produced dose-dependent haemorrhagic ulcers. Thus, the results suggest that coupling of NO and diclofenac contribute to improved gastric tolerability while retaining the anti-inflammatory properties of diclofenac.

    Contribution of host genetic backgrounds in the development of gastric microbiota has not been clearly defined. This study was aimed to characterize the biodiversity, structure and composition of gastric microbiota among twins. A total of four pairs of twins and eight unrelated individuals were enrolled in the study. Antral biopsies were obtained during endoscopy. The bacterial 16S rRNA gene was amplified and pyrosequenced. Sequences were analyzed for the composition, structure, and α and β diversities of gastric microbiota. Proteobacteria, Firmicutes, Bacteroidetes, Actinobacteria, and Fusobacteria were the most predominant phyla of gastric microbiota. Each individual, twins as well as unrelated individuals, harbored a microbiota of distinct composition. There was no evidence of additional similarity in the richness and evenness of gastric microbiota among co-twins as compared to unrelated individuals. Calculations of θ YC and PCoA demonstrated that the structure similarity of gastric microbial community between co-twins did not increase compared to unrelated individuals. In contrast, the structure of microbiota was altered enormously by Helicobacter pylori infection. These results suggest that host genetic backgrounds had little effect in shaping the gastric microbiota. This property of gastric microbiota could facilitate the studies discerning the role of microbiota from genetic grounds in the pathogenesis.

  12. Helicobacter pylori Diversity and Gastric Cancer Risk

    2016-03-01

    Full Text Available Gastric cancer is a leading cause of cancer-related death worldwide. Helicobacter pylori infection is the strongest known risk factor for this malignancy. An important goal is to identify H. pylori-infected persons at high risk for gastric cancer, so that these individuals can be targeted for therapeutic intervention. H. pylori exhibits a high level of intraspecies genetic diversity, and over the past two decades, many studies have endeavored to identify strain-specific features of H. pylori that are linked to development of gastric cancer. One of the most prominent differences among H. pylori strains is the presence or absence of a 40-kb chromosomal region known as the cag pathogenicity island (PAI. Current evidence suggests that the risk of gastric cancer is very low among persons harboring H. pylori strains that lack the cag PAI. Among persons harboring strains that contain the cag PAI, the risk of gastric cancer is shaped by a complex interplay among multiple strain-specific bacterial factors as well as host factors. This review discusses the strain-specific properties of H. pylori that correlate with increased gastric cancer risk, focusing in particular on secreted proteins and surface-exposed proteins, and describes evidence from cell culture and animal models linking these factors to gastric cancer pathogenesis. Strain-specific features of H. pylori that may account for geographic variation in gastric cancer incidence are also discussed.

  20. The epidemiology of gastric cancer.

    Roder, David M

    2002-01-01

    Gastric cancer mortality has declined markedly around the world. In South Australia, the reduction approximated 40% over the last 20 years. Possible reasons include: better refrigeration; reduced consumption of salted, smoked, and chemically preserved foods; increased intake of fruit and vegetables; and improved living standards and a greater use of antibiotics, which may have reduced Helicobacter pylori infection. Reductions generally have been greater for intestinal than diffuse histopathologies. Gastric cancer remains the second leading cause of cancer death worldwide, probably accounting for about 10% of newly diagnosed cancers. High rates apply to Japan, China. Central and South America, Eastern Europe, and parts of the Middle East, and low rates to North America, Australia and New Zealand, Northern Europe, and India. Rates usually are higher in lower socioeconomic groups. Five-year relative survivals of around 20% or less are frequently reported. A figure of 50% or more has been cited for Japan, where there has been radiological screening, although this exceptional figure could have been affected artificially by lead-time and related effects. Male-to-female incidence ratios generally are in the 1.5-2.5 range, with higher ratios for intestinal than diffuse cancers and higher-risk populations. In South Australia, the ratio has been 1.8 to one, although higher at 4.6 to one for cardia lesions. Recent increases in cardia cancers, especially in males in populations of European extraction, often are accompanied by increases for esophageal adenocarcinoma. It is estimated that the global burden of gastric cancer could be reduced by up to 50% by dietary changes that included an increased intake of fruit and vegetables.

  1. Inactivation of Smad4 in gastric carcinomas.

    1997-10-01

    Allelic loss of chromosome 18q has been noted in intestinal type gastric adenocarcinomas. Smad4 is a gene located at 18q that was recently cloned in humans and found to be significantly altered in pancreatic cancers. We sought to determine whether Smad4 genetic alterations played a significant role in gastric tumorigenesis by studying 35 gastric adenocarcinomas of all histopathological types and pathological stages. Microdissected specimens were used for mutational analysis of Smad4 at the nucleotide level, including the entire coding region and intron/exon boundaries. Allelic imbalance was also analyzed at the Smad4 locus using two nearby microsatellite markers. One case of apparent biallelic inactivation of Smad4 was found in our study of 35 gastric carcinomas. A nonsense point mutation at codon 334 was demonstrated, which, similar to other Smad4 mutations, is predicted to truncate the conserved COOH-terminal domain of this protein. This Smad4 C to T transition mutation was proven to be somatically acquired. Allelic loss was also noted on chromosome 18q at a marker near Smad4 in this mutated gastric cancer, apparently producing complete inactivation of Smad4 in this tumor. Significant 18q allelic loss (56% of 34 informative cases) was noted in our gastric carcinomas using microsatellite markers near the Smad4 locus, regardless of histological subtype or pathological stage. Additionally, three cases of microsatellite instability were observed. Thus, Smad4 inactivation was noted in our gastric carcinomas; however, this event was rare. The frequent loss of chromosomal arm 18q observed in gastric cancers suggests the presence of other tumor suppressor genes in this region that are involved in gastric tumorigenesis. Further studies are needed to identify these other targets of inactivation during gastric cancer development.

    Prompted by the finding that the radiological incidence of small bowel ascariasis in the patient with gastric carcinoma was unexpectedly lower than the incidence in the normal population, a clinical study was performed to investigate possible relationship between gastric carcinoma and intestinal ascariasis. As a preliminary survey, we reviewed the radiological incidence of ascariasis in a total of 2,446 cases of upper GI series performed at the Department of Radiology, St Mary's Hospital Catholic Medical College. These included 1,573 normal subjects, 146 gastric carcinoma patients, 100 benign gastric ulcer and 249 duodenal ulcer patients and 378 other upper GI diseases. Following the preliminary study, a more accurate parasitologic study was conducted in another 578 normal subjects and 51 gastric carcinoma patients. The radiological incidences of ascaiasis in normal subjects and gastric carcinoma patients were 15.1% and 28.1%, respectively. The incidence of overall helminthiasis including ascaris lumbricoides, trichocephalus trichiurus and trichostrongyloides orientalis in normal subjects of the present series was 73.5%. This figure is virtually the same with 69.1% of the general population incidence reported by Kim, et al. (1971), but the incidence in gastric carcinoma patients was 94.1%. The high incidence pattern of overall helminthiasis in gastric carcinoma patients is, however, reversed as for as ascariasis is concerned. Thus, the incidence of ascariasis of gastric carcinoma patients was much lower than that of normal subjects (9.8% vs 19.4%). From the present observation, it is postulated that there can be some possible antagonistic relationship between evolution of gastric carcinoma and small bowel infestation of ascaris lumbricoides.

    Rosen, P.; Treves, S.T.

    1985-01-01

    Gastroesophageal reflux (GER) may be defined as a dysfunction of the distal esophagus causing return of gastric contents into the esophagus. GER is a rather common problem during infancy, with an incidence estimated as 1 in 500 infants. Several methods are available to diagnose and quantitate GER. These include fluoroscopy after barium feedings, in conjunction with an upper gastrointestinal series; esophageal manometry; endoscopy; pH probe monitoring, in conjunction with a Tuttle Test; and extended pH probe evaluation for a 24-h period. Gastroesophageal scintigraphy has been advocated as an alternative noninvasive study requiring no sedation. Scintigraphy offers the advantages of prolonged observation, high sensitivity, and low radiation exposure

  5. Gastritis, nitrosamines, and gastric cancer

    Energy Technology Data Exchange (ETDEWEB)

    Stemmermann, G.N.; Mower, H.

    1981-01-01

    Gastritis is associated with peptic ulcer, gastroenterostomy, pernicious anemia, and exposure to nitrosamines. Once established, the process may be self-perpetuating, resulting in atrophy, metaplasia, dysplasia, and neoplasia. This can be explained by the process of endogenous nitrosation of amines in the inflamed gastric mucosa. Evidence is presented to support this hypothesis. Several drugs given parenterally have been identified as mutagenic nitroso compounds in homogenates of human and canine antral mucosa. Nitrite for this process is apparently derived from the inflamed mucosa. Different amines appear to be nitrosated at different places in the antrum, suggesting the presence of site-specific enzymes that control these reactions.

    Various embolic agents have been used for embolization of acute gastrointestinal (GI) arterial bleeding. N-butyl cyanoacrylate (NBCA) is not easy to handle, but it is a useful embolic agent. In this retrospective study, we describe our experience with NBCA embolization of acute gastroduodenal ulcer bleeding. NBCA embolization was performed in seven patients with acute upper GI arterial bleeding; they had five gastric ulcers and two duodenal ulcers. NBCA embolization was done in the left gastric artery (n = 3), right gastric artery (n = 2), gastroduodenal artery (n = 1) and pancreaticoduodenal artery (n = 1). Coil was used along with NBCA in a gastric bleeding patient because of difficulty in selecting a feeding artery. NBCA was mixed with Lipiodol at the ratio of 1:1 to 1:2. The blood pressure and heart rate around the time of embolization, the serial hemoglobin and hematocrit levels and the transfusion requirements were reviewed to evaluate hemostasis and rebleeding. Technical success was achieved in all the cases. Two procedure-related complications happened; embolism of the NBCA mixture to the common hepatic artery occurred in a case with embolization of the left gastric artery, and reflux of the NBCA mixture occurred into the adjacent gastric tissue, but these did not cause any clinical problems. Four of seven patients did not present with rebleeding, but two had rebleeding 10 and 16 days, respectively, after embolization and they died of cardiac arrest at 2 months and 37 days, respectively. One other patient died of sepsis and respiratory failure within 24 hours without rebleeding. NBCA embolization with or without other embolic agents could be safe and effective for treating acute gastroduodenal ulcer bleeding.

    To investigate the causes of gastric wall shortening in early gastric cancer, upper gastrointestinal study was correlated with pathologic findings. We evaluated 41 cases (M:F = 1.7:1, average age = 49) of early gastric cancer, retrospectively. The gastric wall shortening were classified as Grade I; none, Grade II; intermediate, and Grade III; prominent. Pathologic findings such as size of lesions, depth of tumor invasion, degree of the submucosal fibrosis, degree of thickness of the submucosa and muscularis propria, and morphologic patterns of lesions including conversing mucosal folds were correlated with the degree of gastric wall shortening on upper gastrointestinal series. Submucosal fibrosis was present in 4 cases in Grade I (n = 21), 4 cases in Grade II (n = 6) and 8 cases in Grade III (n = 10). Positive conversing mucosal folds were seen in 5 cases in Grade I (n = 17), 0 case in Grade II (n = 2) and 9 cases in Grade III (n = 9). Gastric wall shortening was significantly associated with submucosal fibrosis and conversing mucosal folds of early gastric cancer. (ρ = 0.0001, and ρ = 0.02, respectively) Upper gastrointestinal finding of gastric wall protrusion in patients with early gastric cancer should not misinterprete as advanced gastric cancer since the finding could be a result of submucosal fibrosis

    2002-01-01

    Background: The 5-year survival of patients with completely resected node-positive gastric cancer ranges from 15% to 25%. We explored the feasibility of a chemoradiation regime consisting of concomitant hyperfractionated radiotherapy and 5-fluorouracil protracted venous infusion (5-FU PVI). Materials and Methods: Forty patients received a total or partial gastrectomy operation and D2 nodal resection for Stage III gastric cancer; they were then irradiated by linac with 6-15-MV photons. The target included the gastric bed, the anastomosis, stumps, and regional nodes. A total dose of 55 Gy was given in 50 fractions using 1.1 Gy b.i.d. All patients received a concomitant 200 mg/m2/day 5-FU PVI. Patients were examined during the follow-up period as programmed. Toxicity was recorded according to RTOG criteria. Results: After a median follow-up of 75.6 months (range: 22-136 months), 24 (60%) patients had died, and 16 (40%) were alive and free of disease. The 5-year actuarial incidence of relapse was 39%, 22%, and 2% for distant metastases, out-field peritoneal seeding, and in-field local regional recurrences, respectively. The 5-year actuarial cause-specific survival was 43%. Three patients survived more than 11 years. Acute ≥ Grade 3 toxicity consisted of hematologic (22.5%) and gastrointestinal toxicity (nausea and vomiting 22.5%, diarrhea 2.8%, and abdominal pain 2.6%). No late toxicity was observed. Conclusion: This regime of concomitant 5-FU PVI and hyperfractionated radiotherapy was well tolerated and resulted in successful locoregional control and satisfactory survival

    This case control study presents data on the concentrations of nitrite and nitrate and a variety of pro-inflammatory cytokines such as interleukin-1 beta (IL-1 beta), interleukin-2R (IL-2R), interleukin-6 (IL-6), interleukin-8 (IL-8) and tumor necrosis factor TNF-alpha in gastric fluid and serum. Patients with gastritis, gastric ulcer and gastric cancer are studied and grouped according to infection by Helicobacter pylori. The 208 patients who underwent upper gastrointestinal endoscopic examination were classified as follows; H. pylori-positive gastritis (n = 32), H. pylori-negative gastritis (n = 32), H. pylori-positive ulcers (n = 34), H. pylori-negative ulcers (n = 34), 43 patients with H. pylori-positive gastric cancer in addition to 33 H. pylori-negative healthy control individuals. Gastric fluids and blood samples were taken concomitantly. Cytokines and nitrite and nitrate determinations were attempted as soon as possible after collection of the samples. Nitrite and nitrate levels of serum and gastric fluids of H. pylori-positive gastritis and ulcers were higher than H. pylori-negative gastritis and ulcers. The concentrations of total nitrite and nitrate and cytokines (TNF-alpha, IL-2R, IL-6, and IL-8) in gastric fluids and sera of H. pylori-positive gastric cancer patients were higher than H. pylori-negative control groups. IL-1 beta level was significantly elevated in gastric fluid of infected cancer patients but not in serum. Taken together, the results suggest that an increase in cytokine-NO combination in gastric mucosa previously reported by many studies is not restricted to local infected gastric tissue but also detected in gastric fluid and sera of H. pylori-positive subjects and may have an important role in the pathogenesis and development of common gastric diseases.

    The major objective of the study was to evaluate the gastroprotective property of andrographolide, a chief component of the leaves of Andrographis paniculata in terms of the ulcer preventive effect in rats. An acute toxicity test was conducted with different concentrations of andrographolide to determine the LD(50) value. The dose responsive study was conducted in rats pretreated with andrographolide (1, 3 and 5 mg/kg) for a period of 30 days, prior to ulcer induction by administering ethanol, aspirin or by pyloric ligation. The ulcer protective efficacy was tested by determining the ulcer score, pH, pepsin, titrable acidity, gastric mucin, lipid peroxides, reduced glutathione, and enzymatic antioxidants superoxide dismutase, catalase and glutathione peroxidase in gastric tissue. The activities of H(+)-K(+) ATPase and myeloperoxidase were also determined in gastric tissue. The LD(50) value was found to be 48 mg/kg b. wt and the effective dose was found to be 3 mg/kg. We have observed a significant reduction in the ulcer score in rats pretreated with 3 mg of andrographolide/kg body weight. A favourable increase in the pH and decrease in titrable acidity were observed in the gastric fluid of rats pretreated with the test drug. The gastric tissue H(+)-K(+) ATPase and myeloperoxidase activities were elevated in ulcer-induced animals. The elevation in the enzyme activity was significantly minimized in the andrographolide received animals. The antioxidants and mucin levels were significantly maintained in the gastric tissue of drug-pretreated animals. Andrographolide did not produce any toxic effects in normal rats. This study reveals that the ulcer preventive efficacy of andrographolide may probably due to its antioxidant, cytoprotective and antiacid secretory effects.

    Combining restraint with cold temperature (4°C) consistently induces gastric ulceration in rats after 3.5 h. The cold restraint-stress (CRS) method provides a suitable model for acute ulcer investigations. This study compares the antiulcer activities of lansoprazole (a proton pump inhibitor), PD-136450 (CCK(2)/gastrin receptor antagonist) and ranitidine (histamine H(2) receptor antagonist) on CRS-induced gastric ulcers in rats. The results have shown that lansoprazole, which is a potent anti-secretory agent, provides complete protection in this model of ulcer formation. The use of indomethacin pretreatment to inhibit the prostaglandin (PG) synthesis and N(G)-nitro L-arginine methyl ester (L-NAME) pretreatment to inhibit nitric oxide synthase did not alter the lansoprazole-induced inhibition of ulcer index obtained in the untreated Wistar rats indicating that these two systems were not involved in the activation of lansoprazole. PD-136450, an effective anti-secretory agent against gastrin- but not dimaprit-induced stimulation, evoked a dose-dependent inhibition of CRS-induced gastric ulcers. The results show that both PG and nitric oxide pathways can influence the inhibitory effect of PD-136450 against CRS-induced gastric ulcer. The antiulcer activities of both lansoprazole and PD-136450 were compared to that of ranitidine. The results showed that ranitidine was more potent than lansoprazole and PD-136450 in inhibiting CRS-induced gastric ulcers and its effect was shown to be influenced by PG as well as nitric oxide synthase. The results of this study have demonstrated that although lansoprazole, PD-136450 and ranitidine were protective against CRS-induced gastric ulcers, the antiulcer activities of PD-136450 and ranitidine involved both PG and nitric oxide pathways, while lansoprazole acted independently of these two systems during CRS.

    Objective: To study the changes of CEA and IL-6 contents in blood and gastric juice in patients with gastric cancer and gastritis. Methods: CEA and IL-6 contents in blood and gastric juice were measured with RIA in 60 patients and 30 controls. Results: Gastric juice CEA and IL-6 contents in patients with gastric carcinoma were significantly higher than those in the controls (p < 0.001), however, CEA and IL-6 contents in patients with gastritis and controls were not much different. Conclusion: Gastric juice CEA and IL-6 assay is of diagnostic significance in patients with gastric malignant tumor

  15. Gastric cancer stem cells: A novel therapeutic target

    2013-01-01

    Gastric cancer remains one of the leading causes of global cancer mortality. Multipotent gastric stem cells have been identified in both mouse and human stomachs, and they play an essential role in the self-renewal and homeostasis of gastric mucosa. There are several environmental and genetic factors known to promote gastric cancer. In recent years, numerous in vitro and in vivo studies suggest that gastric cancer may originate from normal stem cells or bone marrow–derived mesenchymal cells, and that gastric tumors contain cancer stem cells. Cancer stem cells are believed to share a common microenvironment with normal niche, which play an important role in gastric cancer and tumor growth. This mini-review presents a brief overview of the recent developments in gastric cancer stem cell research. The knowledge gained by studying cancer stem cells in gastric mucosa will support the development of novel therapeutic strategies for gastric cancer. PMID:23583679

    Pythiosis is caused by the agent Pythium insidiosum, an aquatic oomycete of the kingdom Stramenopila. To describe the symptoms, pathological changes and diagnosis methods of gastric pythiosis in dogs. A three-year-old female German shepherd, with access to wetlands, was attended due to vomiting and recurrent diarrhea of 30 days of duration. A palpable mass in the abdomen filling the left epigastric region was identified in the clinical examination. Simple and contrasted radiological examination and ultrasound of abdominal cavity were performed. The animal was referred for exploratory laparotomy for the removal of the mass. The extent of the mass prevented from the excision and the animal was euthanized. Samples of the tumor mass were collected and sent for morphological study and immunohistochemistry. The changes observed in imaging studies were consistent with gastric pythiosis. In cytology and histopathology, non-septate hyphae were identified, and in immunohistochemistry a strong positivity of anti-Pythium antibodies was observed, confirming the diagnosis of pythiosis. Pythiosis in dogs is diagnosed late and tends to evolve in the animal's death. The definitive diagnosis is by cytology, histology and immunohistochemistry.

    The present work has the objective to review the importance of the images in the preoperating stage of the gastric cancer. It has been emphasized in the modalities of transabdominal ultrasound as much as endoscopic and TAC since they are most valuable in the stage. Certainly the importance of conventional radiology (gastroduodenal series) is also valuable in the stage of the tumor, specially in considering the depth of the same one. In order to make this overhaul, the recent bibliography was consulted but, specially the published one by Japaneses since they follow a classification and methodology different from the used one in most of the countries that belong to the World-wide Organization of the Health. They made an overhaul of approximately 200 cases of patients who have been diagnosed and treated in the Center of Detection of Gastric Cancer of Cartago. In each case review the file, radiological, sonographic and pathological studies, and the cases were chosen that better illustrated the exposed subjects. (Author) [es

    We have studied bone scintigrams in 60 patients with gastric cancer. Of these 60 patients, bone metastases were found in 15 patients (25 %). There were no evidence of bone metastases in polypoid lesions, cancers of the antrum, carcinomas in situ, advanced cancers without invasion to serosa, cancer with N 0 or N 1 regional lymph node metastases, highly deferenciated adenocarcinomas and papillary adenocarcinomas. On the contrary, high rates of bone metastases were seen in cancers of the corpus, advanced cancers with invasion to neighbouring structures and tubular adenocarcinomas. Of these 15 patients with bone metastasis, 3 patients showed very similar clinical features and the findings of ''diffuse bone metastases on bone scintigrams.'' Cancer of the antrum showed high rates of liver metastases, while cancers of the corpus showed high rates of bone stastases. Sixty percent of the patients with bone metastases did not have liver metastases and there seemed to be no significant relationship between liver metastases and bone metastases. From these results we suppose that non-portal tract through the vertebral venous plexus instead of portal tract may be the other route of bone metastases from gastric cancer. (author)

    A comprehensive literature review was made of the methods of screening (pepsinogen test, gastrin-17, anti HP, SGD and Endoscopy). The review and descriptive study of the scientific literature related to the subject was conducted in the scientific databases: Pud Med, MD Consult and Medscape, from August 2013 to March 2014. 65 articles were found related to the topic. The review has included 47 items, assigned according to the criteria of inclusion and exclusion. Available methods were defined of high cost, difficult to spread, little sensitive, little specific and invasive. Endoscopy has had limitations of cost, quality, morbidity, mortality and availability. Pepsinogen tests and helicobacter pylori have helped identify the population at risk for later sift with endoscopy; but it is a very sensitive method. Endoscopy is recommended every two years in the population at risk (patients between 50 and 70 years with a family history of gastric cancer, chronic atrophic gastritis, Helicobacter pylori infection, intestinal metaplasia and dysplasia, patients with symptomatology of dyspepsia and with positive pepsinogen test) is a higher method than SGD in cost, sensitivity and specificity similar to invasive level. The training of the endoscopists should be strengthened in early gastric cancer detection since the detection depends on the quality of endoscopy [es

    Gastric leiomyosarcoma is a rare tumor. Its clinical symptoms are non specific, its diagnosis during preoperative is generaly difficult. Surgery is the main therapeutic pillar because neither radiation nor chemical therapy have proven to be effective.Even though its prognosis taken globally is more favorable than of adenocarcinoma, its biologic behavior is hi gly and depends on various factors. In this paper the author conduct a retrospective analysis of seven cases of gastric leiomyosarcoma s treated in health care centers throughout Uruguay, not only in Montevideo but in other towns as well, during the period extending as from 1992 through 2001. In no case was diagnosis made in the pre or intra operative; in 43% of cases there occurred tumor involvement of the surgical resection margins. Local resections were the most frequent procedures employed, there being no operative mortality, survivals being 5 and 9 years and in 2 others survival extended to 10 years.The three remaining ones have not as yet completed the first year

    Radix Codonopsis has been used in traditional Chinese medicine for strengthening the immune system, improving poor gastrointestinal function, treating gastric ulcers and chronic gastritis and so on. In the present study, an inulin-type fructan CP-A was obtained from the roots of Codonopsis pilosula (Franch.) Nannf. and its structure was confirmed by MS and NMR as (2 → 1) linked-β-d-fructofuranose. The protective effects of CP-A against ethanol-induced acute gastric ulcer in rats were intensively investigated. A Lacy assay demonstrated that CP-A-treated group (50 mg/kg) showed the gastric damage level 1, which was similar to the positive control group, while the model group exhibited the gastric damage level 3. The Guth assay demonstrated that the mucosa ulcer index for CP-A groups at the doses of 50 mg/kg and 25 mg/kg significantly decreased compared with that in the model group ( p CP-A significantly increased the activities of SOD and GSH-Px, and decreased the contents of MDA and NO, and the activity of MPO in gastric tissue in a dose-dependent manner ( p CP-A were likely the potential component in Radix Codonopsis for treatment of acute gastric ulcers.

    Patients with cancer are at high risk for thrombotic events, which are known collectively as Trousseau's syndrome. Herein, we report a 66-year-old male patient who was diagnosed with terminal stage gastric cancer and liver metastasis and who had an initial clinical presentation of upper gastrointestinal bleeding. Acute ischemia of the left lower leg that resulted in gangrenous changes occurred during admission. Subsequent angiography of the left lower limb was then performed. This procedure revealed arterial thrombosis of the left common iliac artery with extension to the external iliac artery, the left common iliac artery, the posterior tibial artery, and the peroneal artery, which were occluded by thrombi. Aspiration of the thrombi demonstrated that these were not tumor thrombi. The interesting aspect of our case was that the disease it presented as arterial thrombotic events, which may correlate with gastric adenocarcinoma. In summary, we suggested that the unexplained thrombotic events might be one of the initial presentations of occult malignancy and that thromboprophylaxis should always be considered.

    Gastric lipomas are rare tumors, accounting for 2%-3% of all benign gastric tumors. They are of submucosal or extremely rare subserosal origin. Although most gastric lipomas are usually detected incidentally, they can cause abdominal pain, dyspeptic disorders, obstruction, invagination, and hemorrhages. Subserosal gastric lipomas are rarely symptomatic. There is no report on treatment of subserosal gastric lipomas in the English literature. We present a case of a 50-year-old male with symptom...

    THE HCI in the mammalian stomach is concentrated enough to digest the stomach itself, yet the gastric epithelium remains undamaged. One protective factor is gastric mucus, which forms a protective layer over the surface epithelium1-4 and acts as a diffusion barrier5,6 Bicarbonate ions secreted by the gastric epithelium7 are trapped in the mucus gel, establishing a gradient from pH 1-2 at the lumen to pH 6-7 at the cell surface8-10. How does HCI, secreted at the base of gastric glands by parietal cells, traverse the mucus layer without acidifying it? Here we demonstrate that injection of HCI through solutions of pig gastric mucin produces viscous fingering patterns11-18 dependent on pH, mucin concentration and acid flow rate. Above pH 4, discrete fingers are observed, whereas below pH 4, HCI neither penetrates the mucin solution nor forms fingers. Our in vitro results suggest that HCI secreted by the gastric gland can penetrate the mucus gel layer (pH 5-7) through narrow fingers, whereas HC1 in the lumen (pH 2) is prevented from diffusing back to the epithelium by the high viscosity of gastric mucus gel on the luminal side.

    Pepsinogen I and Pepsinogen II (PG I and PG II) were purified from human gastric mucosa using DE-52 anion exchange chromatography, Gel filtration HPLC and Q-2 anion exchange fast pressure chromatography. The antiserums against at both PG I and PG II were established respectively by preparing 125 I-PG I and 125 I-PG II using the chloramine-T method. Serum Pepsinogen I and II levels were measured by RIA in 190 healthy controls and other gastric diseases. The results were analyzed by statistics method. Compared with healthy controls, the serum PG I levels of duodenal ulcer patients and gastric ulcer were significantly higher. The serum PG I levels of gastritis patients were significantly lower and the serum PG I levels and PG I/PG II ratio of gastric cancer patients were much more lower. After total gastrectomy, the serum PG I and PG II levels of patients with recurrence of gastric cancer were significantly higher than those without recurrence. The changes of serum PG I and PG II levels are valuable for the diagnosis of gastric cancer and detecting the recurrence of gastric cancer after total gastrectomy

A trend of steady decline in gastric cancer incidence rates is the effect of the increased standards of hygiene, conscious nutrition, and Helicobacter pylori eradication, which together constitute primary prevention. Avoidance of gastric cancer remains a priority. However, patients with higher risk should be screened for early detection and chemoprevention. Surgical resection enhanced by standardized lymphadenectomy remains the gold standard in gastric cancer therapy. This review briefly summarizes the most important aspects of gastric cancers, which include epidemiology, risk factors, classification, diagnosis, prevention, and treatment. The paper is mostly addressed to physicians who are interested in updating the state of art concerning gastric carcinoma from easily accessible and credible source.

  8. Gastric angiogenesis and Helicobacter pylori infection

    Directory of Open Access Journals (Sweden)

    I. D. Pousa

    Full Text Available The formation of new blood vessels seen in conditions commonly associated with Helicobacter pylori (H. pylori infection, including gastritis, peptic ulcer, and gastric carcinoma, prompts consideration of a potential relationship between mucosal colonization by this organism and the angiogenic process. H. pylori directly or indirectly damages endothelial cells, which induces a number of changes in the microvasculature of the gastric mucosa. In H. pylori-associated conditions, that is, in gastritis, peptic ulcer and gastric carcinoma, there is an increased concentration of angiogenic factors, and subsequently a formation of new blood vessels. However, this early angiogenesis -which is activated to repair the gastric mucosa- is subsequently inhibited in patients with peptic ulcer, and ulcer healing is thus delayed. This may be due to the antiproliferative action of this organism on endothelial cells. While the angiogenic process becomes inhibited in infected patients with peptic ulcer, it remains seemingly active in those with gastritis or gastric cancer. This fact is in support of the notion suggested by various studies that peptic ulcer and gastric cancer are mutually excluding conditions. In the case of gastric cancer, neoangiogenesis would enhance nutrient and oxygen supply to cancer cells, and thus tumor growth and metastatic spread.

    To investigate the possibility that an abnormality of gastric emptying exists in duodenal ulcer and to determine if such an abnormality persists after ulcer healing, scintigraphic gastric emptying measurements were undertaken in 16 duodenal ulcer patients before, during, and after therapy with cimetidine; in 12 patients with pernicious anemia, and in 12 control subjects. No difference was detected in the rate or pattern of gastric emptying in duodenal ulcer patients before and after ulcer healing with cimetidine compared with controls, but emptying of the solid component of the test meal was more rapid during treatment with the drug. Comparison of emptying patterns obtained in duodenal ulcer subjects during and after cimetidine treatment with those obtained in pernicious anemia patients and controls revealed a similar relationship that was characterized by a tendency for reduction in the normal differentiation between the emptying of solid and liquid from the stomach. The similarity in emptying patterns in these groups of subjects suggests that gastric emptying of solids may be influenced by changes in the volume of gastric secretion. The failure to detect an abnormality of gastric emptying in duodenal ulcer subjects before and after ulcer healing calls into question the widespread belief that abnormally rapid gastric emptying is a feature with pathogenetic significance in duodenal ulcer disease.

    The prodromal syndrome of radiation sickness is characterized by nausea and vomiting but the pathophysiology and the treatment of this entity is largely unknown. The authors investigated this problem by determining the effects of ionizing radiation on gastric function with and without administration of the dopamine antagonist domperidone. They measured gastric electrical control activity (waves per minute), fractional emptying rate (percent per minute), acid output (microequivalents per minute), and plasma levels of immunoreactive beta-endorphin. Twelve conscious, chair-adapted rhesus monkeys were studied twice before, once immediately after, and once 2 days after a single 800-cGy (800 rads) /sup 60/Co total body irradiation. In addition to causing vomiting, total body irradiation transiently suppressed gastric electrical control activity, gastric emptying and gastric secretion, while increasing plasma levels of immunoreactive beta-endorphin. Domperidone had no effect on vomiting or gastric function either before or after irradiation, but it significantly increased plasma immunoreactive beta-endorphin.

    Full Text Available Ectopic breast tissue has the ability to undergo all the pathological changes of the normal breast, including breast cancer. Gastrointestinal metastasis of breast cancer is rarely observed and it is very difficult to differentiate gastric metastases from primary gastric cancer. We present a case of 52-year-old female, who suffered from abdominal pain. Physical examination showed a palpable mass in the left anterior axilla and computerized tomography revealed gastric wall thickening with linitis plastica. When gastroscopic biopsy showed no signs of malignancy, excisional biopsy was performed in the left axilla. Histological examination revealed invasive lobular carcinoma of the breast, consistent with ectopic breast cancer. Further gastroscopic submucosal biopsies and immunohistochemical studies revealed gastric metastases of invasive lobular carcinoma. Axillary ectopic breast tissue carcinomas can mimic axillary lymphadenopathies. Additionally, gastric metastasis of breast cancer is an uncommon but possible condition. To the best of our knowledge, this is the first report of ectopic breast cancer with gastric metastasis.

  15. Do calories or osmolality determine gastric emptying

    Recent animal studies suggest that gastric emptying is dependent on the caloric and osmotic content of the ingested food. These studies have involved intubation with infusion of liquid meals into the stomach. Scintigraphic methods, which are non-invasive and do not alter normal physiology, are now available for precise quantitation of gastric emptying. To study the role of calories and osmolality on gastric emptying, the authors employed a standardized /sup 99m/Tc-scrambled egg meal washed with 50 cc tap water in 10 normal human volunteers. A variety of simple and complex sugars, non-absorbable complex carbohydrate (polycose), medium chain fatty acid (MCFA) and gluten were dissolved in water and ingested with the test meal. Each subject acted as his own control. Coefficient of variation in control tests in each subject 12 weeks apart was 9.9%. Results showed that incremental glucose (25-66 gm) produced a linear increase in gastric emptying (T/2 control 50 +- 3, 25 gm 60 +- 3, 50 gm 79 +- 3 and 66 gm 102 +- 3 minutes). 25 gm fructose (T/2 59 +- 3 minutes) and 25 gm polycose (T/2 59 +- 3 minutes) had similar effects to glucose. 25 gm sucrose and 25 gm gluten did not significantly differ from controls. MCFA had an effect similar to 50 gm glucose - suggesting that calories are important in gastric emptying. However, 25 gm xylose markedly prolonged gastric emptying to 80 +- 5 minutes. The rank order for osmolality for substances tested MCFA = gluten < polycose < polycose < fructose < sucrose = glucose < xylose defined no relationship to gastric emptying. The authors' results suggest that neither calories nor osmolality alone determine gastric emptying. A specific food does not necessarily have the same effect on gastric emptying in different individuals

Results showed that incremental glucose (25-66 gm) produced a linear increase in gastric emptying (T/2 control 50 +- 3, 25 gm 60 +- 3, 50 gm 79 +- 3 and 66 gm 102 +- 3 minutes). 25 gm fructose (T/2 59 +- 3 minutes) and 25 gm polycose (T/2 59 +- 3 minutes) had similar effects to glucose. 25 gm sucrose and 25 gm gluten did not significantly differ from controls. MCFA had an effect similar to 50 gm glucose - suggesting that calories are important in gastric emptying. However, 25 gm xylose markedly prolonged gastric emptying to 80 +- 5 minutes. The rank order for osmolality for substances tested MCFA = gluten < polycose < polycose < fructose < sucrose = glucose < xylose defined no relationship to gastric emptying. The authors' results suggest that neither calories nor osmolality alone determine gastric emptying. A specific food does not necessarily have the same effect on gastric emptying in different individuals.

    2004-01-01

    Retrospectively, 243 dogs with radiographic evidence of gastric dilatation-volvulus (GDV) were studied for radiographic signs of pneumatosis (intramural gas), pneumoperitoneum, splenomegaly, and severity of gastric distention. The sensitivity, specificity, and predictive value of these imaging signs as predictors of gastric wall necrosis, as determined by visual inspection at surgery or necropsy, were determined. The sensitivity and specificity of gastric pneumatosis were 14.1% and 92.7%, respectively. The prevalence of gastric wall necrosis was 26.6%. The positive and negative predictive values of gastric pneumatosis for predicting gastric necrosis were 40.9% and 74.9%, respectively. Gastric pneumatosis and pneumoperitoneum were identified together in four dogs. Pneumoperitoneum, either alone or in conjunction with pneumatosis, yielded similar results as a test for gastric necrosis. Splenomegaly and severity of gastric distention were insensitive and nonspecific for gastric wall necrosis. Splenomegaly did not predict the need for splenectomy at surgery. Although pneumatosis and pneumoperitoneum are relatively specific signs of gastric wall necrosis, the utility of these signs as a test for gastric necrosis is limited in clinical practice. The significance of pneumatosis should be taken into consideration with previous treatments for gastric decompression, as percutaneous gastric trocharization or orogastric intubation may increase the number of false-positive results.

    2017-06-01

    Gastric dilatation volvulus (GDV) was identified in six adult maned wolves ( Chrysocyon brachyurus ) housed at the Smithsonian Conservation Biology Institute in Front Royal, Virginia, and the Dickerson Park Zoo in Springfield, Missouri. Four individuals were found dead in their enclosures, and GDV was diagnosed postmortem based on radiographic and necropsy findings. Two individuals were diagnosed with GDV antemortem, with one wolf surviving following surgical intervention and supportive management. A concurrent splenic torsion was identified in three of six cases. Although GDV has been well documented in domestic dogs and is known to occur in maned wolves, objective, detailed case descriptions have been limited in this species. This report represents the first description of a surviving case of GDV in the maned wolf. Thorough species-specific documentation of any acutely fatal condition, such as GDV, is imperative for proper case recognition and medical management, with profound implications for species recovery efforts.

    Full Text Available Herbal medicines appeared promising in prevention of many diseases. This study was conducted to investigate the gastroprotective effect of Curcuma xanthorrhiza leaf in the rats induced gastric ulcer by ethanol. Normal and ulcer control received carboxymethycellulose (5 mL/kg orally, positive control was administered with 20 mg/kg omeprazole (reference drug and 2 groups were received 250 mg/kg and 500 mg/kg of the leaf extract, respectively. To induce of gastric ulcers formation, ethanol (5 mL/kg was given orally to all groups except normal control. Gross ulcer areas, histology, and amount of prostaglandin E2, superoxide dismutase and malondialdehyde were assessed to determine the potentiality of extract in prevention against gastric ulcers. Oral administration of extract showed significant gastric protection effect as the ulcer areas was remarkably decreased. Histology observation showed less edema and leucocytes infiltration as compared with the ulcer control which exhibited severe gastric mucosa injury. Furthermore, the leaf extract elevated the mucus weight, level of prostaglandin E2 and superoxide dismutase. The extract also reduced malondialdehyde amount significantly. Results showed leaf extract of Curcuma xanthorrhiza can enhanced the gastric protection and sustained the integrity of gastric mucosa structure. Acute toxicity test did not showed any sign of toxicity (2 g/kg and 5 g/kg.

    Background/Aims: Helicobacter pylori gastritis is a risk factor for the development of gastric cancer. The results of several studies indicate that gastric adenomas, which are considered premalignant lesions, may also be associated with H pylori gastritis. However, it is not clear whether there are different patterns of gastritis in these patients compared with patients with gastric cancer or patients with H pylori gastritis alone. Therefore, this study was designed to investigate the pattern...

    This study was designed to investigate the role of PDGF-DD secreted by gastric cancer-derived mesenchymal stem cells (GC-MSCs) in human gastric cancer progression. Gastric cancer cells were indirectly co-cultured with GC-MSCs in a transwell system. The growth and migration of gastric cancer cells were evaluated by cell colony formation assay and transwell migration assay, respectively. The production of PDGF-DD in GC-MSCs was determined by using Luminex and ELISA. Neutralization of PDGFR-β by su16f and siRNA interference of PDGF-DD in GC-MSCs was used to demonstrate the role of PDGF-DD produced by GC-MSCs in gastric cancer progression. GC-MSC conditioned medium promoted gastric cancer cell proliferation and migration in vitro and in vivo. Co-culture with GC-MSCs increased the phosphorylation of PDGFR-β in SGC-7901 cells. Neutralization of PDGFR-β by su16f blocked the promoting role of GC-MSC conditioned medium in gastric cancer cell proliferation and migration. Recombinant PDGF-DD duplicated the effects of GC-MSC conditioned medium on gastric cancer cells. Knockdown of PDGF-DD in GC-MSCs abolished its effects on gastric cancer cells in vitro and in vivo. PDGF-DD secreted by GC-MSCs is capable of promoting gastric cancer cell progression in vitro and in vivo. Targeting the PDGF-DD/PDGFR-β interaction between MSCs and gastric cancer cells may represent a novel strategy for gastric cancer therapy.

    Atrophic gastritus or intestinal metaplasia is the precursor to many gastric carcinomas that arise in a dysplatic epithelium. The authors retrospectively reviewed the radiographic features of the gastric mucosa in 30 patients with the pathologic diagnosis of intestinal metaplasia (27) or atrophic gastritus (3). In 12 patients (40%) the area gastricae were enlarged to 5 mm or greater. In these 12 patients and in an additional 11 (total of 23, or 76%), a polypoid-nodular gastric mucosal pattern was seen. These findings and patterns are illustrated, and the differential diagnosis and clinical implications are discussed

    2016-10-01

    Intrathoracic stomach is a rare and serious congenital abnormality. The anomaly may be complicated by gastric volvulus and can lead to ischemic gastric infarction in the neonate. If diagnosed antenatally, neonatal management can be planned in advance so as to reduce morbidity. This anomaly must be differentiated from the more common congenital diaphragmatic hernia, as associated pulmonary hypoplasia is common in the latter and rare with gastric herniation. We report a case of intrathoracic stomach in a neonate without volvulus, fortunately a rare entity which was managed operatively, and the child has been under regular follow-up.

  6. Gastric carcinoma: when is palliative gastrectomy justified?

    2011-12-01

    Full Text Available Gastric carcinoma is frequently diagnosed with an advanced stage of non-curable tumor growth characterized by infiltration of the gastric serosa, peritoneal tumor spread and/or metastases within lymph nodes and liver. Currently, there is a controversy on the value of palliative resection with regard to the safety and benefit to the patient outcome. Based on the available literature, this overview summarizes the various aspects and interprets the limited data on the palliative resection of gastric carcinoma. It turns out that the available study results may indicate potential for an improved quality of life and a prolongation of survival if an acceptable morbidity and mortality are present.

    Full Text Available The common acid related diseases of the upper gastrointestinal tract could be considered as primarily due to the defect in barrier function either of the gastric mucosal or duodenal epithelium leading to the formation of gastric or duodenal ulcers. An attempt was made in this review to discuss the classification, pathophysiology, diagnosis and treatment of gastric ulcer in dogs. Early surgical advances in the management of peptic ulcers are emphasized that were then subsequently replaced by pharmacological treatment (histamine H2-receptor antagonists, proton pump inhibitors and considered as the major strategy against the acid disorders.

    Full Text Available Gastric cancer remains a major cause of cancer mortality in the world. However, in the past 10 decades, the view of gastric cancer has been changing. This includes the unexplained decline in the incidence of the cancer, the proximal shift of the cancer in the stomach, the identification of Helicobacter pylori as an etiological agent, rapid development in molecular tumour biology, new treatment modalities and the adoption of mass screening for prevention. This article reviews the changing views of gastric cancer and the latest developments.

  9. Does remnant gastric cancer really differ from primary gastric cancer? A systematic review of the literature by the Task Force of Japanese Gastric Cancer Association.

    Remnant gastric cancer, most frequently defined as cancer detected in the remnant stomach after distal gastrectomy for benign disease and those cases after surgery of gastric cancer at least 5 years after the primary surgery, is often reported as a tumor with poor prognosis. The Task Force of Japanese Gastric Cancer Association for Research Promotion evaluated the clinical impact of remnant gastric cancer by systematically reviewing publications focusing on molecular carcinogenesis, lymph node status, patient survival, and surgical complications. A systematic literature search was performed using PubMed/MEDLINE with the keywords "remnant," "stomach," and "cancer," revealing 1154 relevant reports published up to the end of December 2014. The mean interval between the initial surgery and the diagnosis of remnant gastric cancer ranged from 10 to 30 years. The incidence of lymph node metastases at the splenic hilum for remnant gastric cancer is not significantly higher than that for primary proximal gastric cancer. Lymph node involvement in the jejunal mesentery is a phenomenon peculiar to remnant gastric cancer after Billroth II reconstruction. Prognosis and postoperative morbidity and mortality rates seem to be comparable to those for primary proximal gastric cancer. The crude 5-year mortality for remnant gastric cancer was 1.08 times higher than that for primary proximal gastric cancer, but this difference was not statistically significant. In conclusion, although no prospective cohort study has yet evaluated the clinical significance of remnant gastric cancer, our literature review suggests that remnant gastric cancer does not adversely affect patient prognosis and postoperative course.

    1. We investigated the effect of the haemostatic agent ethamsylate on aspirin-induced gastric mucosal bleeding. 2. Eighteen healthy subjects were studied three times: at the end of 48 h periods of treatment with (a) placebo, (b) aspirin 600 mg four times daily, (9 doses) and (c) aspirin 600 mg four times daily with each dose preceded by ethamsylate 500 mg. 3. At the end of each treatment period gastric mucosal bleeding into timed gastric washings was quantified using the orthotolidine reaction. 4. Aspirin increased bleeding from a rate on placebo of 1.2 microliters 10 min-1 geometric mean (95% confidence limits) (0.7-1.8) microliters 10 min-1 to 20.0 (11.6-34.2) microliters 10 min-1, (P less than 0.01). The rate of bleeding after aspirin preceded by ethamsylate [14.1 (8.5-23.4) microliters 10 min-1] was not significantly different from that after aspirin alone. 5. We conclude that ethamsylate does not reduce acute aspirin-induced gastric mucosal bleeding in healthy humans.

    2016-05-31

    Gastric volvulus is a clinically significant cause of acute or recurrent abdominal pain and chronic vomiting in children. Since related clinical symptoms are nonspecific, clinicians often refer to radiologists for a diagnostic evaluation. Early diagnosis is crucial to prevent life-threatening complications of prolonged volvulus, such as intestinal ischemia, infarction, strangulation, necrosis, and perforation that may require immediate surgical treatment. In this report, we describe clinical and radiological criteria for diagnosis of gastric volvulus in children. We describe two pediatric clinical cases. A 16-month-old female Caucasian child was admitted to our hospital for recurrent postprandial vomiting episodes, which started at 11 months old, associated with failure to thrive. A 9-month-old term-born baby boy was admitted for chronic, recurrent, postprandial vomiting, which started at 7 months of age, with progressive failure to thrive. A barium study allowed definitive diagnosis of chronic organoaxial gastric volvulus. Gastric volvulus is an extremely rare disorder in the pediatric population. It can be considered a complex clinical condition with regard to the etiology and the management. A nonoperative approach is advisable in the absence of warning signs.

  12. Ablation of capsaicin sensitive afferent nerves impairs defence but not rapid repair of rat gastric mucosa.

    Capsaicin sensitive afferent neurones have previously been reported to play a part in gastric mucosal protection. The aim of this study was to investigate whether these nociceptive neurones strengthen mucosal defence against injury or promote rapid repair of the damaged mucosa, or both. This hypothesis was examined in anaesthetised rats whose stomachs were perfused with ethanol (25 or 50% in saline, wt/wt) for 30 minutes. The gastric mucosa was inspected 0 and 180 minutes after ethanol had been given at the macroscopic, light, and scanning electron microscopic level. Rapid repair of the ethanol injured gastric mucosa (reduction of deep injury, partial re-epithelialisation of the denuded surface) took place in rats anaesthetised with phenobarbital, but not in those anaesthetised with urethane. Afferent nerve ablation as a result of treating rats with a neurotoxic dose of capsaicin before the experiment significantly aggravated ethanol induced damage as shown by an increase in the area and depth of mucosal erosions. Rapid repair of the injured mucosa, however, as seen in rats anesthetised with phenobarbital 180 minutes after ethanol was given, was similar in capsaicin and vehicle pretreated animals. Ablation of capsaicin sensitive afferent neurones was verified by a depletion of calcitonin gene related peptide from the gastric corpus wall. These findings indicate that nociceptive neurones control mechanisms of defence against acute injury but are not required for rapid repair of injured mucosa.

    Despite the decreasing popularity of gastric banding, a large number of patients still have a band in situ. Although immediate postoperative complications are relatively rare, long-term complications of gastric banding are more common but are not reported to occur after band removal. We report a case of gastric volvulus and subsequent ischaemic perforation in a patient shortly after band removal, resulting in emergency laparotomy and total gastrectomy. Severe continuing pain persisting after band deflation and even gastric band removal should be treated as an emergency and urgent investigation should not be delayed.

    Acetylcholinesterase inhibition by organophosphorus pesticides or organophosphate nerve agents can cause acute parasympathetic system dysfunction, muscle weakness, seizures, coma, and respiratory failure. Prognosis depends on the dose and relative toxicity of the specific compound, as well as pharmacokinetic factors. We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute organophosphorus poisoning? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 62 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: activated charcoal (single or multiple doses), alpha(2) adrenergic receptor agonists, atropine, benzodiazepines, butyrylcholinesterase replacement therapy, cathartics, extracorporeal clearance, gastric lavage, glycopyrronium bromide (glycopyrrolate), ipecacuanha (ipecac), magnesium sulphate, milk or other home remedy immediately after ingestion, N-methyl-D-aspartate receptor antagonists, organophosphorus hydrolases, oximes, removing contaminated clothes and washing the poisoned person, and sodium bicarbonate.

    Diverse colony morphologies are a hallmark of Burkholderia pseudomallei recovered from infected patients. We observed that stresses that inhibit aerobic respiration shifted populations of B. pseudomallei from the canonical white colony morphotype toward two distinct, reversible, yet relatively stable yellow colony variants (YA and YB). As accumulating evidence supports the importance of B. pseudomallei enteric infection and gastric colonization, we tested the response of yellow variants to hypoxia, acidity, and stomach colonization. Yellow variants exhibited a competitive advantage under hypoxic and acidic conditions and alkalized culture media. The YB variant, although highly attenuated in acute virulence, was the only form capable of colonization and persistence in the murine stomach. The accumulation of extracellular DNA (eDNA) was a characteristic of YB as observed by 4',6-diamidino-2-phenylindole (DAPI) staining of gastric tissues, as well as in an in vitro stomach model where large amounts of eDNA were produced without cell lysis. Transposon mutagenesis identified a transcriptional regulator (BPSL1887, designated YelR) that when overexpressed produced the yellow phenotype. Deletion of yelR blocked a shift from white to the yellow forms. These data demonstrate that YB is a unique B. pseudomallei pathovariant controlled by YelR that is specifically adapted to the harsh gastric environment and necessary for persistent stomach colonization. Seemingly uniform populations of bacteria often contain subpopulations that are genetically identical but display unique characteristics which offer advantages when the population is faced with infrequent but predictable stresses. The pathogen Burkholderia pseudomallei is capable of forming several reversible colony types, and it interconverted between one white type and two yellow types under certain environmental stresses. The two yellow forms exhibited distinct advantages in low-oxygen and acidic environments. One yellow

    An ethanolic extract of Parsley, Petroselinum crispum (Mill.) Nym.ex A.W. Hill (Umbelliferae), was tested for its ability to inhibit gastric secretion and to protect gastric mucosa against the injuries caused by pyloric ligation, hypothermic restraint stress, indomethacin and cytodestructive agents (80% ethanol, 0.2 M NaOH and 25% NaCl) in rats. The extract in doses of 1 and 2 g/kg body weight had a significant antiulcerogenic activity on the models used. Besides, ethanol-induced depleted gastric wall mucus and non-protein sulfhydryl contents were replenished by pretreatment with Parsley extract. Acute toxicity tests showed a large margin of safety for the extract. The phytochemical screening of Parsley leaves revealed the presence of tannins, flavonoids, sterols and/or triterpenes.

    Gastric ulceration properties (gastrointestinal toxicity) of the sodium salt of 4-(0-β-D-glucopyranosyloxy) benzoic acid, a new nonsteroidal anti-inflammatory drug (NSAID) intended for the treatment of chronic inflammatory diseases of the kidney and urinary tract, have been tested on laboratory animals. Acute NSAID-induced gastropathy was induced in rats by oral administration of indomethacin, nimesulide, diclofenac, acetylsalicylic acid and the new drug. Test animals were killed by instantaneous decapitation 4 h after treatment and their gastrointestinal tracts were studied by pathomorphological methods on micropreparations and histological sections of gastric mucosa. It was established that the new drug, in contrast to reference NSAIDS, did not exhibit gastropathic action on the gastric mucosa.

  19. Gastric Adenocarcinoma: A Multimodal Approach

    Directory of Open Access Journals (Sweden)

    Humair S. Quadri

    2017-08-01

    Full Text Available Despite its declining incidence, gastric cancer (GC remains a leading cause of cancer-related deaths worldwide. A multimodal approach to GC is critical to ensure optimal patient outcomes. Pretherapy fine resolution contrast-enhanced cross-sectional imaging, endoscopic ultrasound and staging laparoscopy play an important role in patients with newly diagnosed ostensibly operable GC to avoid unnecessary non-therapeutic laparotomies. Currently, margin negative gastrectomy and adequate lymphadenectomy performed at high volume hospitals remain the backbone of GC treatment. Importantly, adequate GC surgery should be integrated in the setting of a multimodal treatment approach. Treatment for advanced GC continues to expand with the emergence of additional lines of systemic and targeted therapies.

    We present a case of giant gastric trichobezoar retrieved through a long gastrotomy in a 40 years old married women from rural Sindh with unreported psychological disturbance. Trichobezoar almost exclusively occur in females with an underlying psychiatric disorder. It has an insidious development of symptoms which accounts for its delayed presentation and large size at the time of diagnosis. They are associated with trichophagia (habit of compulsive hair eating) and are usually diagnosed on CT Scans or upper GI Endoscopy. They can give rise to complications like gastro-duodenal ulceration, haemorrhage, perforation, peritonitis or obstruction with a high rate of mortality. The treatment is endoscopic, laparoscopic or surgical removal and usually followed by psychiatric opinion. (author)

  4. Gastric varicella: two cases in cancer patients

    Directory of Open Access Journals (Sweden)

    Violeta María Sastre-Lozano

    Full Text Available Gastric involvement with the varicella-zoster virus is an uncommon clinical condition where early suspicion and diagnosis are important to prevent the consequences deriving from its high morbidity and mortality, which in immunocompromised patients oscillate between 9% and 41% according to the various series. Two cases of gastric involvement with the varicella-zoster virus (VZV in two patients with blood cancer are reported below. Gastric lesions are usually preceded by typical papulovesicular skin lesions. When gastric involvement is the first symptom of the disease its diagnosis and management may be delayed, which may entail severe consequences for immunocompromised patients. It is therefore that we suggest its inclusion in the algorithm for immunocompromised patients with abdominal pain and ulcer-like endoscopic lesions.

    Cytomegalovirus (CMV) sometimes causes gastritis, especially in immunocompromised patients, but whether CMV gastritis promotes the development of gastric cancer is unknown. Here, we report a case of gastric cancer that developed in the presence of CMV gastritis, which had been present for at least 4 years and was refractory to treatment. An 80-year-old woman had noted epigastric discomfort and appetite loss. Esophagogastroduodenoscopy revealed a shallow geographical ulcer extending from the upper body to the pylorus. Histological findings of the biopsy and serology were suggestive of CMV gastritis. Serum anti-Helicobacter pylori antibody test was positive, suggesting co-infection with CMV and H. pylori. Her gastritis was unimproved with repeated antiviral therapy and eradication of H. pylori. Thirty months later, wide-spread gastric cancer had developed. We suggest the possibility that the addition of chronic inflammation of CMV infection to H. pylori-induced gastritis facilitated the development of gastric cancer.

    Full Text Available Primary gastric masses are rare in childhood, and a gastric ganglioneuroma has not been reported in the pediatric population. In this report, we describe a 12-year-old female who presented with iron deficiency anemia and melena. Endoscopy was performed to elucidate the source of her symptoms, and revealed a gastric mass with overlying ulceration. Following resection and pathologic examination, the mass was diagnosed as a solitary polypoid ganglioneuroma. A solitary polypoid ganglioneuroma is an uncommon, benign tumor of neural crest cell origin. They are most often asymptomatic and found incidentally, but can present with rectal bleeding, obstruction, pain, and changes in bowel function. Complete resection is the therapy of choice to prevent progression of symptoms or rare transformation into a malignant neuroblastic tumor, like neuroblastoma. As of the patient's last post-operative appointment, she was healthy with resolution of her anemia. Keywords: Ganglioneuroma, Pediatric, Gastric mass, Anemia, Neuroblastic tumor

    One thousand-four hundred and twenty-four cases of gastric cancer registered at the Nagasaki Tumor Registry between 1973 and 1977 were studied. The incidence of gastric cancer tended to be higher in persons exposed to the atomic bomb within 2.0 km from the hypocenter, especially in young persons, than in non-exposed individuals, but the difference was not statistically significant. Compared with the nonexposed, the corrected relative risk of gastric cancer in persons exposed within 2.0 km from the hypocenter was 1.28 in males and 1.11 in females. In terms of histologic type or location, the incidence of gastric cancer showed no statistically significant difference between the exposed and nonexposed persons. (author)

  8. Isthmus Stem Cells Are the Origins of Metaplasia in the Gastric Corpus

    Directory of Open Access Journals (Sweden)

    Yoku Hayakawa MD,, PhD

    2017-07-01

    Full Text Available The acquisition of genetic/epigenetic mutations in long-lived gastrointestinal stem cells leads to the development of cancer, as well as precancerous lesions such as metaplasia and dysplasia. In the proximal stomach corpus, this model of progression from stem cells has been supported by studies in mice and human beings, showing abundant proliferation in the isthmus and clonal expansion of mutated cells from the stem cell region. An alternative theory proposes that gastric metaplasia arises from mature differentiated chief cells. Despite reports of low levels of proliferation in chief cells in acute injury models, there is little evidence for reprogramming of chief cells into long-lived stem cells that continuously supply progeny over time. Critical flaws in the chief cell transdifferentiation theory include the definition of acute SPEM, the chief cell-damaging effect of chemical reagents, and the specificity of chief cell lineage tracing. In contrast, there is now strong evidence regarding the stem cell origins of gastric metaplasia that refutes the transdifferentiation theory. Here, we briefly review the history and definition of gastric metaplasia, and outline in detail the evidence that supports the stem cell origin of metaplasia.

    In this study Fourier analysis was applied to condensed images of gastric emptying with the aim of evaluating the amplitude and frequency of gastric contractions as well as gastric emptying in patients with various well-defined disorders. In 15 controls, 65 patients with progressive systemic sclerosis (PSS), 41 patients with diabetes mellitus type I (DM), 12 patients with pyloric stenosis and 9 patients who had undergone gastric surgery, gastric emptying was determined after ingestion of a semi-solid test meal. In addition, condensed images were generated to evaluate the amplitude and frequency of gastric contractions by means of Fourier analysis. In PSS and DM patients, gastric emptying and contraction amplitudes were significantly reduced (P<0.01). Patients with pyloric stenosis displayed regular peristalsis but significantly delayed emptying (P<0.01). Patients who had undergone gastric surgery showed normal or rapid gastric emptying associated with decreased amplitudes (P<0.01). The frequency of gastric contractions in the patient groups was not different from that in controls. This study showed Fourier analysis of condensed images to be a rapid and feasible approach for the evaluation of gastric contractions. Depending on the underlying disorder, gastric emptying and peristalsis showed both corresponding and discrepant findings. Data on gastric contractions provided additional information compared with results obtained by conventional emptying studies. Therefore, both parameters should be routinely assessed to further improve characterisation of gastric dysfunction by scintigraphy. (orig.)

    Our main objective was to study gastritis associated to duodeno-gastric reflux. It is about a longitudinal study case/witness, paired according to the sex and the age. It was unrolled from February 2005 to January 2006 in the digestive diseases department of the hospital Gabriél Touré, and endoscopic centers of Promenade des Angevins, and clinique Farako. The patients profited from an upper digestive endoscopy to appreciate endoscopic aspect of gastritis associated to bile in the stomach mucus lake. The gastric biopsies were systematic. This study included 50 patients having gastritis associated to bile in gastric mucus lake compared to 50 patients having gastritis associated to clearly gastric mucus lake. The sex-ratio was 1.26 in favour of men. The average age of the patients was of 41.30 +/- 15.43 years. On the symptomatic hand, fetid breath was significantly met in duodeno-gastric reflux (p = 0.013). Potash consumption in the "tô" (millet cake) was significantly reported in gastritis associated to bile in gastric mucus lake (p = 0.042). The endoscopic aspects were comparable. Histological aspects of nonatrophic chronic gastritis were significantly mint in witnesses as well into the antrum as into the fundus (p = 0.0001 and p = 0.00023). The reactional gastritis aspect was the prerogative of duodenogastric reflux (p ranging between 10(-6) and 3.10 (-6). Helicobacter pylori infection was found comparable in the two groups (p = 0.297). Dysplasia although rare was found only in gastritis associated to duodeno-gastric reflux. Gastritis associated to bile in gastric mucus does not se,nm to have specific clinical, endoscopic and histological presentation. However the presence of dysplasia must have an attentive monitoring.

    Minimally invasive surgery for gastric cancer is a relatively new research field, with convincing results mostly stemming from Asian countries. The use of the robotic surgery platform, thus far assessed as a safe procedure, which is also easier to learn, sets the background for a wider spread of minimally invasive technique in the treatment of gastric cancer. This review will cover the literature published so far, analyzing the pros and cons of robotic surgery and highlighting the remaining study questions. PMID:26798433

    Gastric ischemia is a rare condition associated with poor prognosis. Our study aim was to highlight the clinical features and outcomes of patients with gastric ischemia. A retrospective review of patients diagnosed with isolated gastric ischemia at our institution from January 1, 2000, to May 5, 2016, was performed. Demographic, clinical, endoscopic, radiologic, and outcome variables were abstracted for analysis. Seventeen patients (65% men) with mean age of 69.3 ± 11.3 years and body mass index of 28.8 ± 11.1 were identified. The etiologies for gastric ischemia included local vascular causes (n = 8), systemic hypoperfusion (n = 4), and mechanical obstruction (n = 5). The most common presenting symptoms were abdominal pain (65%), gastrointestinal bleeding (47%), and altered mental status (23%). The typical endoscopic appearance was mucosal congestion and erythema with or without ulceration. Gastric pneumatosis and portal venous air were more commonly seen on CT imaging. Radiologic and/or surgical intervention was needed in 9 patients, while the remaining 8 patients were managed conservatively with acid suppression, antibiotics, and nasogastric tube decompression. The median duration of hospital stay was 15 days (range 1-36 days). There were no cases of rebleeding and the mortality rate as a direct result of gastric ischemia was 24% within 6 months of diagnosis. Although uncommon, gastric ischemia is associated with significant mortality. Endoscopy and CT imaging play an important role in its diagnosis. The management of gastric ischemia is dictated by its severity and associated comorbidities.

    To compare on the basis of helical CT findings gastric wall thickening of peptic gastric ulcer with that of gastric adenocarcinoma with ulcer. Thirty-eight patients with pathologically proven gastric lesion (17 cases of peptic ulcer and 21 cases of ulcerative or ulceroinfiltrative gastric cancer (Borrman type II, III) underwent helical CT, and the findings were retrospectively reviewed in terms of maximum abnormal wall thickness, preservation of the inner enhancing layer, the presence three discriminate layers of gastric wall, and enhancement pattern. The enhancement pattern of abnormally thick wall was compared with that of the portal phase of back muscle, and was defined as low, iso, or high. The Chi-square test and Student t test were used for statistical analysis. In cases of peptic ulcer and gastric cancer with ulceration, maximum abnormal wall thickness was 7-30 (mean, 16.1)mm, and 11-33 (mean, 21.8)mm, respectively. The inner enhancing layer was preserved in 15 of 17 patients (88.2%) and one of 21 (4.8%); three discriminate layers of gastric wall were observed in 8 of 17 patients (47.0%), and one of 21 (4.8%). The enhancement pattern was low in 12 of 17 patients (70.5%), and 3 of 21 (14.3%); iso in 4 of 17 (23.5%), and 4 of 21 (19.0%), and high in one of 17 (5.9%), and 14 of 21 (66.7%). All figures refer, respectively, to the two distinct conditions. In terms of preservation of the inner enhancing layer, three discriminate layers of gastric wall, and a low enhancement pattern, there were statistically significant differences between peptic ulcer and gastric adenocarcinoma with ulcer. Where the enhancement was high, however, the statistically significant difference between the two conditions was even greater. There was no statistically significant difference in terms of gastric wall thickness or iso-attenuation of thickened gastric.

    To study the effect of itopride on gastric accommodation, gastric emptying and drinking capacity in functional dyspepsia (FD). Randomized controlled trial was conducted to check the effect of itopride on gastric accommodation, gastric emptying, capacity of tolerating nutrient liquid and symptoms of FD. We recruited a total of 31 patients having FD on the basis of ROME III criteria. After randomization, itopride was received by 15 patients while 16 patients received placebo. Gastric accommodation was determined using Gastric Scintigraphy. 13 C labeled octanoic breadth test was performed to assess gastric emptying. Capacity of tolerating nutrient liquid drink was checked using satiety drinking capacity test. The intervention group comprised of 150 mg itopride. Patients in both arms were followed for 4 wk. Mean age of the recruited participant 33 years (SD = 7.6) and most of the recruited individuals, i.e ., 21 (67.7%) were males. We found that there was no effect of itopride on gastric accommodation as measured at different in volumes in the itopride and control group with the empty stomach ( P = 0.14), at 20 min ( P = 0.38), 30 min ( P = 0.30), 40 min ( P = 0.43), 50 min ( P = 0.50), 60 min ( P = 0.81), 90 min ( P = 0.25) and 120 min ( P = 0.67). Gastric emptying done on a sub sample ( n = 11) showed no significant difference ( P = 0.58) between itopride and placebo group. There was no significant improvement in the capacity to tolerate liquid in the itopride group as compared to placebo ( P = 0.51). Similarly there was no significant improvement of symptoms as assessed through a composite symptom score ( P = 0.74). The change in QT interval in itopride group was not significantly different from placebo (0.10). Our study found no effect of itopride on gastric accommodation, gastric emptying and maximum tolerated volume in patients with FD.

    Objective: The relationship between gastroesophageal reflux disease (GERD) and gastric emptying rate was investigated. Results of endoscopy, 24-hour esophageal pH monitoring were also evaluated. Methods: 15 patients were evaluated with endoscopy, pH monitoring and radionuclide gastric emptying. The results were compared with that of 17 control subjects. Correlations of gastric emptying rate and esophagitis, 24-hour pH monitoring between GERD patients and control subjects were also analyzed. Results: Liquid gastric emptying rate of GERD patients was significantly lower than that of control subjects at 15 and 30 min (P 0.05), but there exhibited a linear correlation between 50% solid emptying time and esophagus pH total score (r=0.643, P<0.05). Conclusions: The results indicate a delayed liquid and solid gastric emptying in GERD patients. There is a linear correlation between 50% solid emptying time and esophagus pH total score. Delayed gastric emptying may be an important factor in the pathogenesis of GERD

    The Epstein-Barr virus (EBV) is detected in about 10% of gastric carcinoma cases throughout the world. In EBV-associated gastric carcinoma, all tumor cells harbor the clonal EBV genome. Gastric carcinoma associated with EBV has distinct clinicopathological features, occurs predominately in men and in younger-aged individuals, and presents a generally diffuse histological type. Most cases of EBV-associated gastric carcinoma exhibit a histology rich in lymphocyte infiltration. The immunological reactiveness in the host may represent a relatively preferable prognosis in EBV-positive cases. This fact highlights the important role of EBV in the development of EBV-associated gastric carcinoma. We have clearly proved direct infection of human gastric epithelialcells by EBV. The infection was achieved by using a recombinant EBV. Promotion of growth by EBV infection was observed in the cells. Considerable data suggest that EBV may directly contribute to the development of EBV-associated GC. This tumor-promoting effect seems to involve multiple mechanisms, because EBV affects several host proteins and pathways that normally promote apoptosis and regulate cell proliferation.

    During 22 years from 1968 through 1989, 538 A-bomb survivors were operated on for gastric cancer, accounting for 30.9% of 1,741 surgical cases of gastric cancer during that period. To determine whether age at the time of exposure to A-bombing might influenced the occurrrence of gastric cancer, these A-bomb survivors were compared with 1,138 other non-exposed gastric cancer patients. According to age at the time of exposure, the 538 A-bomb survivors were divided into those under the age of 19 (118), those in their twenties (134), those in their thirties (178), and those over the age of 40 (108). The largest number of gastric cancer was those in their thirties at the time of exposure, followed by the twenties, 19 years or less, and 40 years or more in the exposed group. The younger A-bomb survivors were at the time of exposure, the earlier gastric cancer occurred. These findings were common to the non-exposed group. Postoperative 5-year survival rate was 72.0% in A-bomb survivors aged 19 years or less at the time of exposure, which was better than the other age groups. This may be explained by active participation in health examination for A-bomb survivors. (N.K.)

    To investigate the protective effect of compound bismuth and magnesium granules on aspirin-induced gastric mucosal injury in rats and its possible mechanism. Acute gastric mucosal injury model was developed with intraperitoneal injection of aspirin in Wistar rats. The rats were divided into normal control group, injury group, sucralfate protection group, compound bismuth and magnesium granules protection group and its herbal components protection group(each group 12 rats). In the protection groups, drugs as mentioned above were administered by gavage before treated with intraperitoneal injection of aspirin. To evaluate the extent of gastric mucosal injury and the protective effect of drugs, gastric mucosal lesion index, gastric mucosal blood flow, content of gastric mucosal hexosamine, prostaglandins (PG), nitric oxide(NO), tumor necrosis factor (TNF), and interleukin (IL) -1, 2, 8 were measured in each group, and histological changes were observed by gross as well as under microscope and electron microscope. Contents of hexosamine, NO, and PG in all the protection groups were significantly higher than those in the injury group (all Pcompound bismuth and magnesium granules group was significantly higher than that in the sucralfate group ((11.29±0.51) vs(10.80±0.36)nmol/ml, Pcompound bismuth and magnesium granules group were significantly lower than those in the sucralfate group ((328.17±6.56) vs(340.23±8.05)pg/ml, PCompound bismuth and magnesium granules and its herbal components may have significant protective effect on aspirin-induced gastric mucosal injury.

    Purpose: The goal of this study was to evaluate dosimetric parameters, acute toxicity, pathologic response, and local control in patients treated with preoperative intensity-modulated radiation therapy (IMRT) and concurrent chemotherapy for localized gastric adenocarcinoma. Methods: Between November 2007 and April 2010, 25 patients with localized gastric adenocarcinoma were treated with induction chemotherapy, followed by preoperative IMRT and concurrent chemotherapy and, finally, surgical resection. The median radiation therapy dose was 45 Gy. Concurrent chemotherapy was 5-fluorouracil and oxaliplatin in 18 patients, capecitabine in 3, and other regimens in 4. Subsequently, resection was performed with total gastrectomy in 13 patients, subtotal gastrectomy in 7, and other surgeries in 5. Results: Target coverage, expressed as the ratio of the minimum dose received by 99% of the planning target volume to the prescribed dose, was a median of 0.97 (range, 0.92-1.01). The median V{sub 30} (percentage of volume receiving at least 30 Gy) for the liver was 26%; the median V{sub 20} (percentage of volume receiving at least 20 Gy) for the right and left kidneys was 14% and 24%, respectively; and the median V{sub 40} (percentage of volume receiving at least 40 Gy) for the heart was 18%. Grade 3 acute toxicity developed in 14 patients (56%), including dehydration in 10, nausea in 8, and anorexia in 5. Grade 4 acute toxicity did not develop in any patient. There were no significant differences in the rates of acute toxicity, hospitalization, or feeding tube use in comparison to those in a group of 50 patients treated with preoperative three-dimensional conformal radiation therapy with concurrent chemotherapy.

    Purpose: The goal of this study was to evaluate dosimetric parameters, acute toxicity, pathologic response, and local control in patients treated with preoperative intensity-modulated radiation therapy (IMRT) and concurrent chemotherapy for localized gastric adenocarcinoma. Methods: Between November 2007 and April 2010, 25 patients with localized gastric adenocarcinoma were treated with induction chemotherapy, followed by preoperative IMRT and concurrent chemotherapy and, finally, surgical resection. The median radiation therapy dose was 45 Gy. Concurrent chemotherapy was 5-fluorouracil and oxaliplatin in 18 patients, capecitabine in 3, and other regimens in 4. Subsequently, resection was performed with total gastrectomy in 13 patients, subtotal gastrectomy in 7, and other surgeries in 5. Results: Target coverage, expressed as the ratio of the minimum dose received by 99% of the planning target volume to the prescribed dose, was a median of 0.97 (range, 0.92–1.01). The median V 30 (percentage of volume receiving at least 30 Gy) for the liver was 26%; the median V 20 (percentage of volume receiving at least 20 Gy) for the right and left kidneys was 14% and 24%, respectively; and the median V 40 (percentage of volume receiving at least 40 Gy) for the heart was 18%. Grade 3 acute toxicity developed in 14 patients (56%), including dehydration in 10, nausea in 8, and anorexia in 5. Grade 4 acute toxicity did not develop in any patient. There were no significant differences in the rates of acute toxicity, hospitalization, or feeding tube use in comparison to those in a group of 50 patients treated with preoperative three-dimensional conformal radiation therapy with concurrent chemotherapy. R0 resection was obtained in 20 patients (80%), and pathologic complete response occurred in 5 (20%). Conclusions: Preoperative IMRT for gastric adenocarcinoma was well tolerated, accomplished excellent target coverage and normal structure sparing, and led to appropriate pathologic

    1. No general consensus has been reached on the treatment of acute gastric lesions. The aims of the present study were to clarify the effects of sucralfate, cimetidine and rabeprazole monotherapies and combination therapies on acute gastric lesions from the viewpoint of connective tissue regeneration. 2. Gastric lesions were experimentally created by the oral administration of 50% ethanol-0.15 mol/L HCl to rats. After 30 min, the anti-ulcer agents sucralfate (100 mg/kg), cimetidine (20 mg/kg) and rabeprazole (2 mg/kg) were administered separately or in combination and the stomach was excised at different times to measure the level of hydroxyproline in the gastric mucosa and determine lesion index. Immunostaining against prolylhydroxylase was performed on some specimens. 3. In the control group, lesion index decreased linearly from 30 min after ethanol-HCl administration and the level of mucosal hydroxyproline peaked between 2 and 4 h later. Although sucralfate significantly promoted lesion healing, it had no effect on mucosal hydroxyproline level. Cimetidine suppressed increases in mucosal hydroxyproline and prolonged lesion healing, but these findings were reversed by combining cimetidine and sucralfate. Rabeprazole had no significant effect on lesion healing, but promoted lesion healing in combination with sucralfate. Immunohistochemical analysis showed that prolylhydroxylase was expressed in spindle cells that lined the glandular cells in a boundary area between normal and injured tissues. 4. Under conditions in which the effects of intragastric pH are minimal, sucralfate is superior to antisecretory agents in promoting the healing of acute gastric lesions.

    Gastric metastasis from invasive lobular breast cancer is relatively rare, commonly presented among multiple metastases, several years after primary diagnosis of breast cancer. Importantly, gastric cancer that is synchronously presented with lobular breast cancer can be misdiagnosed as primary gastric cancer; therefore, accurate differential diagnosis is required. A 39-year-old woman was visited to our hospital because of right breast mass and progressive dyspepsia. Invasive lobular carcinoma of breast was diagnosed on core needle biopsy. Gastroscopy revealed a diffuse scirrhous mass at the prepyloric antrum and diagnosed as poorly differentiated adenocarcinoma on biopsy. Synchronous double primary breast and gastric cancers were considered. Detailed pathological analysis focused on immunohistochemical studies of selected antibodies, including those of estrogen receptors, gross cystic disease fluid protein-15, and caudal-type homeobox transcription factor 2, were studied. As a result, gastric lesion was diagnosed as metastatic gastric cancer originating from breast. Right breast conserving surgery was performed, and duodenal stent was inserted under endoscopic guidance to relieve the patient's symptoms. Systemic chemotherapy with combined administration of paclitaxel and trastuzumab was initiated. Forty-one months after the diagnosis, the patient is still undergoing the same therapy. No recurrent lesion has been identified in the breast and evidence of a partial remission of gastric wall thickening has been observed on follow-up studies without new metastatic lesions. Clinical suspicion, repeat endoscopic biopsy, and detailed histological analysis, including immunohistochemistry, are necessary for diagnosis of metastatic gastric cancer from the breast.

    The characteristics of gastric secretion following acute γ exposure (1,500 rd) were studied in pigs with a small Pavlov stomach. Spontaneous secretion was practically inhibited when the animals were taken out of the irradiation cell. It slowly recovered in the following hours and its pH, first neutral, turned acid again. However, till the third day, it did not recover normal characteristics. The excretion of sodium ions was much increased. Under histaminic stimulation, the responses of irradiated pigs and controls were much similar. The secretory capacities of the gastric mucosa were retained but without spontaneous manifestations. As a conclusion, the early troubles following overexposure must be the consequences of regulation disorders rather than of the direct action of radiation on the stomach. (orig.) [de

The hormone is not hypersecreted after the purely restrictive bariatric procedure gastric banding and no case reports exist on improvement in psoriasis......, both a direct anti-inflammatory effect of GLP-1 as well as an indirect effect through weight loss could contribute to improvement in psoriasis. A potential involvement of GLP-1 in the remission of psoriasis observed after bariatric surgery offers exciting possibilities for research and eventually...... bypass surgery in patients with psoriasis may result in complete remission of the disease. A substantial weight loss is achieved in the months following surgery, which is likely to reduce psoriasis symptoms and risk of comorbidities.

    Serum pepsinogens I and II (PGI, PGII) levels were determined by PGI and PGII-RIA kits in 84 healthy controls and 128 patients of gastric diseases including 42 patients with gastric cancer. The results showed peptic ulcer cases had elevated PGI and PGII levels. The atrophic gastritis cases had low PGI levels and the gastric cancer cases had low PGI and low PGI/PGII ratio. Using the cut-off values of PGI<35 μg/L and PGI/PGII<1.5 for clinical purpose, the sensitivity and specificity of the test for gastric cancer was 73% and 78%, respectively. Combined with endoscope examination, the serum PGI and PGII levels are valuable for the early diagnosis of gastric cancer

    To evaluate the feasibility, safety, and clinical outcomes of plug-assisted retrograde transvenous obliteration (PARTO) to treat gastric variceal hemorrhage in patients with portal hypertension. From May 2012 to June 2014, 19 patients (11 men and 8 women, median age; 61, with history of gastric variceal hemorrhage; 17, active bleeding; 2) who underwent PARTO using a vascular plug and a gelfoam pledget were retrospectively analyzed. Clinical and laboratory data were examined to evaluate primary (technical and clinical success, complications) and secondary (worsening of esophageal varix [EV], change in liver function) end points. Median follow-up duration was 11 months, from 6.5 to 18 months. The Wilcoxon signed-rank test was used to compare laboratory data before and after the procedure. Technical success (complete occlusion of the efferent shunt and complete filling of gastric varix [GV] with a gelfoam slurry) was achieved in 18 of 19 (94.7%) patients. The embolic materials could not reach the GV in 1 patient who had endoscopic glue injection before our procedure. The clinical success rate (no recurrence of gastric variceal bleeding) was the same because the technically failed patient showed recurrent bleeding later. Acute complications included fever (n = 2), fever and hypotension (n = 2; one diagnosed adrenal insufficiency), and transient microscopic hematuria (n = 3). Ten patients underwent follow-up endoscopy; all exhibited GV improvement, except 2 without endoscopic change. Five patients exhibited aggravated EV, and 2 of them had a bleeding event. Laboratory findings were significantly improved after PARTO. PARTO is technically feasible, safe, and effective for gastric variceal hemorrhage in patients with portal hypertension

    To evaluate gastric motility using electrical bio-impedance (EBI) and gastric changes as a result of stress induced by psychological tests. A group of 57 healthy women, aged 40-60 years, was recruited, and a clinical history and physical examination were performed. The women were free from severe anxiety, chronic or acute stress, severe depression, mental diseases and conditions that affect gastric activity. The women were evaluated under fasting conditions, and using a four-electrode configuration, the gastric signals were obtained through a BIOPAC MP-150 system. The volunteers were evaluated using the following paradigm: basal state, recording during the Stroop Test, intermediate resting period, recording during the Raven Test, and a final resting period. We analyzed the relative areas of the frequency spectrum: A1 (1-2 cpm), A2 (2-4 cpm), A3 (4-8 cpm), and A4 (8-12 cpm), as well as the median of area A2 + A3. The data were analyzed by an autoregressive method using a Butterworth filter with MatLab and Origin. Analysis of variance (ANOVA) and Friedman ANOVA (for nonparametric variables) were performed; in addition, pairs of groups were compared using the T dependent and Wilcoxon T tests. The results of the main values of area A2 were not significantly different comparing the five steps of the experimental paradigm. Nevertheless, there was a tendency of this A2 region to decrease during the stress tests, with recuperation at the final resting step. When an extended gastric region was considered (1-4 cpm), significant differences with the psychological stress tests were present (F = 3.85, P = 0.005). The A3 region also showed significant changes when the stress psychological tests were administered (F = 7.25, P stress test showed significant changes (F = 5.5, P stress test (P stress can be evaluated by short-term EBI.

    2012-08-01

    Full Text Available Abstract Introduction Amyloidosis most often manifests as a systemic involvement of multiple tissues and organs, and an amyloidal deposit confined to the stomach is extremely rare. It is sometimes difficult to provide a definitive diagnosis of localized gastric amyloidosis by biopsy specimen and diagnosis of amyloidosis in some cases has been finalized only after surgical resection of the stomach. Case presentation A 76-year-old Japanese woman with epigastric discomfort underwent an esophagogastroduodenoscopy procedure. The esophagogastroduodenoscopy revealed gastric wall thickening, suggesting scirrhous gastric carcinoma, at the greater curvature from the upper to the lower part of the gastric corpus. A biopsy specimen revealed amyloid deposits in the submucosal layer with no malignant findings. We resected a representative portion of the lesion by endoscopic mucosal resection using the strip biopsy method to obtain sufficient tissue specimens, and then conducted a detailed histological evaluation of the samples. The resected specimens revealed deposition of amyloidal materials in the gastric mucosa and submucosa without any malignant findings. Congo red staining results were positive for amyloidal protein and exhibited green birefringence under polarized light. Congo red staining with prior potassium permanganate incubation confirmed the light chain (AL amyloid protein type. Based on these results, gastric malignancy, systemic amyloidosis and amyloid deposits induced by inflammatory disease were excluded and this lesion was consequently diagnosed as localized gastric amyloidosis. Our patient was an older woman and there were no findings relative to an increase in gastrointestinal symptoms or anemia, so no further treatment was performed. She continued to be in good condition without any finding of disease progression six years after verification of our diagnosis. Conclusions We report an unusual case of primary amyloidosis of the stomach

  1. History of Helicobacter pylori, duodenal ulcer, gastric ulcer and gastric cancer.

    Science.gov (United States)

    2014-05-14

    Helicobacter pylori (H. pylori) infection underlies gastric ulcer disease, gastric cancer and duodenal ulcer disease. The disease expression reflects the pattern and extent of gastritis/gastric atrophy (i.e., duodenal ulcer with non-atrophic and gastric ulcer and gastric cancer with atrophic gastritis). Gastric and duodenal ulcers and gastric cancer have been known for thousands of years. Ulcers are generally non-fatal and until the 20th century were difficult to diagnose. However, the presence and pattern of gastritis in past civilizations can be deduced based on the diseases present. It has been suggested that gastric ulcer and duodenal ulcer both arose or became more frequent in Europe in the 19th century. Here, we show that gastric cancer and gastric ulcer were present throughout the 17th to 19th centuries consistent with atrophic gastritis being the predominant pattern, as it proved to be when it could be examined directly in the late 19th century. The environment before the 20th century favored acquisition of H. pylori infection and atrophic gastritis (e.g., poor sanitation and standards of living, seasonal diets poor in fresh fruits and vegetables, especially in winter, vitamin deficiencies, and frequent febrile infections in childhood). The latter part of the 19th century saw improvements in standards of living, sanitation, and diets with a corresponding decrease in rate of development of atrophic gastritis allowing duodenal ulcers to become more prominent. In the early 20th century physician's believed they could diagnose ulcers clinically and that the diagnosis required hospitalization for "surgical disease" or for "Sippy" diets. We show that while H. pylori remained common and virulent in Europe and the United States, environmental changes resulted in changes of the pattern of gastritis producing a change in the manifestations of H. pylori infections and subsequently to a rapid decline in transmission and a rapid decline in all H. pylori-related diseases.

PCO2 in both samples was measured using a blood gas analyzer (AVL 945; AVL List GMBH, Gratz, Austria). These measurements were taken at various time points in each patient, and under various haemodynamic and oxygen transport conditions, All measurements were performed with the patient fasted. Correlation between the two measurements was examined using the Bland-Altman technique. We also performed an in vitro study to quantify the precision and bias for the AVL 945. For this purpose, a stable PCO2 in saline solution was achieved by bubbling 5% carbon dioxide calibration gas. Results: We performed 112 pairs of measurements in 15 patients. Table 1 shows clinical data and the first values of arterial, tonometered and gastric juice PCO2 for each patient.

In the basal trial it was found that geronts gastric emptying is delayed more than controls (112 and 89 minutes). The activity of Clebopride revealed a significant decrease in both groups, being more important in geronts. This findings suggests the clinic usefulness in different pathological situations, where its useful to accelerate the time of gastric evacuation (gastric esofagic reflux, gastric ulcer) and in the geront with dispeptic symptoms and chronic gastritis related to age, as the only gastric pathology.

  12. Gastric tumors on chest radiographs

    1978-04-01

    Gastric neoplasms of three patients protruded into their gas-containing fornices and were first visualized on plain chest radiographs. Endoscopy and/or surgery confirmed these to be a polyp, a leiomyoma, and an adenocarcinoma. The polyp, 1.3 cm in diameter, was the smallest of these three, but smaller lesions may be detectable under suitable conditions. Adequate technique and positioning, sufficiently large lesions in the upper portion of the stomach, a central beam tangential to the tumor, sufficient gas in the stomach, and careful scrutiny by the observer are required. Lesions may be more readily visualized during chest radiography when oral sodium bicarbonate is used to distend the stomach. In chest radiography, exposure limited to the lung fields has been advocated for economy and dose reduction. However, too small an exposure field may result in loss of information potentially beneficial to the patient. Using the smaller of two popular film sizes (35 x 43 cm and 35 x 35 cm), the saving in surface and bone marrow doses is negligible, and the saving in gonad dose may be nil over that when shielding is used. The interest of the observer may be absorbed by a concomitant cardiac or pulmonary lesion. Careful scrutiny of the entire radiograph is therefore essential. (author)

    Gastric cancer is the fifth most common cancer worldwide. In "Western" countries, most people are either diagnosed at an advanced stage, or develop a relapse after surgery with curative intent. In people with advanced disease, significant benefits from targeted therapies are currently limited to HER-2 positive disease treated with trastuzumab, in combination with chemotherapy, in first-line. In second-line, ramucirumab, alone or in combination with paclitaxel, demonstrated significant survival benefits. Thus, systemic chemotherapy remains the mainstay of treatment for advanced gastric cancer. Uncertainty remains regarding the choice of the regimen. To assess the efficacy of chemotherapy versus best supportive care (BSC), combination versus single-agent chemotherapy and different chemotherapy combinations in advanced gastric cancer. We searched the Cochrane Central Register of Controlled Trials, MEDLINE and Embase up to June 2016, reference lists of studies, and contacted pharmaceutical companies and experts to identify randomised controlled trials (RCTs). We considered only RCTs on systemic, intravenous or oral chemotherapy versus BSC, combination versus single-agent chemotherapy and different chemotherapy regimens in advanced gastric cancer. Two review authors independently identified studies and extracted data. A third investigator was consulted in case of disagreements. We contacted study authors to obtain missing information. We included 64 RCTs, of which 60 RCTs (11,698 participants) provided data for the meta-analysis of overall survival. We found chemotherapy extends overall survival (OS) by approximately 6.7 months more than BSC (hazard ratio (HR) 0.3, 95% confidence intervals (CI) 0.24 to 0.55, 184 participants, three studies, moderate-quality evidence). Combination chemotherapy extends OS slightly (by an additional month) versus single-agent chemotherapy (HR 0.84, 95% CI 0.79 to 0.89, 4447 participants, 23 studies, moderate-quality evidence), which is

    Gastric cancer is the second cause of cancer-related deaths worldwide. Helicobacter pylori is the major risk factor for gastric cancer. As for any type of cancer, T cells are crucial for recognition and elimination of gastric tumor cells. Unfortunately T cells, instead of protecting from the onset of cancer, can contribute to oncogenesis. Herein we review the different types, “friend or foe”, of T-cell response in gastric cancer.

    To evaluate the radiologic findings of gastric MALToma, and to correlate these with its pathologic findings. We retrospectively reviewed the pathologic slides of gastrectomy and gastroscopic biopsy specimens obtained between 1982 and 1996, and collected nine cases of gastric MALToma. Eight of these had been surgically confirmed, and one had been diagnosed by gastroscopic biopsy. A gastrointestinal series comprised eight cases; five involved sonography and five, CT. The lesions were located at the body in five cases, at the antrum in one, and at the body and antrum in three cases. Pathologic diagnosis was low grade MALToma in four cases, and mixed high and low grade MALToma in five cases. Initial radiologic diagnosis was gastric lymphoma in four cases, early gastric carcinoma in three, and advanced gastric carcinoma in two cases. On retrospective analysis, radiologic diagnosis was changed to lymphoma in both cases initially diagnosed as advanced gastric carcinomas. One case showed marked thickening of the gastric wall, with poor enhancement on CT, and the other case showed a very small and shallow ulcer in comparison to diffuse infiltration of tumor in the upper gastrointestinal series. The final radiologic diagnosis was gastric lymphoma in six cases, and early carcinoma in three. Radiologic findings of gastric MALToma were EGC II c-like lesion in three cases, marked gastric wall thickening in two, multiple discrete lesions in two, hyperugosity of gastric folds with discrete lesions in one, and diffuse infiltrative lesion with small ulcer in one case. The pathologic diagnosis of gastric MALToma was made by the presence of lymphoepithelial lesions, centrocyte-like cells, reactive follicles, plasma cell infiltration, and follicular colonization. There were no significant correlations between radiologic findings and pathologic results such as depth of tumor invasion, low grade MALToma or mixed high and low grade MALToma. There are no specific radiologic characteristics

    Gastric diseases, including peptic ulcer disease and gastric cancer, are highly prevalent in human beings. Despite this, the cellular biology of the stomach remains poorly understood relative to other gastrointestinal organs such as the liver, intestine, and colon. In particular, little is known about the molecular basis of stomach development and the differentiation of gastric lineages. Although animal models are useful for studying gastric development, function, and disease, there are major...

    The gastric microbiome has been proposed as an etiological factor in gastric carcinogenesis. We compared the gastric microbiota in subjects presenting with gastric cancer (GC, n = 12) and controls (functional dyspepsia (FD), n = 20) from a high GC risk population in Singapore and Malaysia. cDNA from 16S rRNA transcripts were amplified (515F-806R) and sequenced using Illumina MiSeq 2 × 250 bp chemistry. Increased richness and phylogenetic diversity but not Shannon's diversity was found in GC as compared to controls. nMDS clustered GC and FD subjects separately, with PERMANOVA confirming a significant difference between the groups. H. pylori serological status had a significant impact on gastric microbiome α-diversity and composition. Several bacterial taxa were enriched in GC, including Lactococcus, Veilonella, and Fusobacteriaceae (Fusobacterium and Leptotrichia). Prediction of bacterial metabolic contribution indicated that serological status had a significant impact on metabolic function, while carbohydrate digestion and pathways were enriched in GC. Our findings highlight three mechanisms of interest in GC, including enrichment of pro-inflammatory oral bacterial species, increased abundance of lactic acid producing bacteria, and enrichment of short chain fatty acid production pathways.

    A condensed imaging technique was applied to gastric emptying studies to investigate (a) whether different types of motility disorders may be distinguished by characteristic image patterns and (b) whether the findings obtained provide additional information compared to standard quantitative measurements. Condensed images and quantitative data of gastric emptying were evaluated in 75 consecutive patients with normal function and various disorders such as peptic ulcer, postvagotomy, pyloric obstruction, dumping syndrome, gastoparesis etc. Condensed images were generated from a gastric region of interest. They display the distribution and behaviour of a radioactive test meal in a space-time matrix, whose horizontal and vertical dimensions are temporal and spatial, respectively. As shown in a series of representative examples condensed images disclose a variety of well-defined image patterns reflecting different pathophysiological mechanisms. This qualitative characterization of gastric emptying patterns provided in 34 of the 75 patients (45%) important new information compared to quantitative data. The application of condensed imaging techniques to gastric emptying studies (complementary to quantitative measurements) may, therefore, enhance the diagnostic value of scintigraphic techniques.

    Scintigraphic measurement of gastric emptying time has been reported to be influenced by the variation in depth of radionuclide within the stomach. This study was designed to clarify whether a part of the variability in gastric emptying could be ascribed to a relationship between anterior image, the total anteroposterior image and the tissue attenuation correction(geometric mean). A dual-head scintillation camera(ADAC, USA) was used to investigate effect of such changes. We were performed 16 normal subject gastric emptying studies with 99 mTC labelled scramble egg, milk and solid meal(610 Kcal, 300 g). The results are as follows; On anterior image, T 1/2 emptying time was delayed by 5 min, 6.5%(range : 3 ∼ 18 min, 5∼31.4%) compared with the geometric mean. But there was no different gastric emptying time between the total anteroposterior image and geometric mean. Therefore, if will be useful to use the method of geometric mean or the total anteroposterior image to evaluate the gastric emptying time accurately

    Objective was to present a histopathologic and immunohistochemical analysis of primary gastric lymphomas that was reclassified according to the new World Health Organization classification of lymphoid neoplasms. We reviewed the morphological and immunohistochemical features of 28 patients with gastric lymphomas, diagnosed in the Department of pathology at the University Hospital of Tishreen University, Lattakia, Syria, during the period 1994-2003. Specimens were obtained from endoscopic and surgical biopsies. The immunohistochemical study was performed to analyze the immunophenotype of these lymphomas. Patients were aged 17-71 years. There was a slight predominance of females (male to female ratio, 13:15). Seventeen of the patients had tumors mainly located in the gastric antrum. Histologically, the most common lymphoma was of mucosa-associated lymphoid tissue (MALT) type (20 patients), also with diffuse large B-cell lymphoma (7 patients) and anaplastic large cell lymphoma (one patient). Our study demonstrates the different patterns of gastric lymphomas in Lattakia, Syria during a 10-year period in 28 Syrian patients, and reveals that the most primary gastric lymphomas are B-cell MALT lymphomas.

    Full Text Available Gastric dilatation and volvulus syndrome (GDV in dogs is an abnormal accumulation of gastric gas (dilatation, which may be complicated by rotation of the stomach (volvulus about its mesentric axis. A number of factors, both environmental and host have been implicated in GDV. This syndrome has a variety of effects on the cardiovascular, respiratory, gastrointestinal, metabolic, haemolymphatic-immune, renal and central nervous systems. Clinical signs include distended, painful, tympanic abdomen, retching, unproductive vomiting, hypersalivation, respiratory distress accompanied by varying degrees of shock. Treatment of GDV includes medical and fluid therapy at shock dosages to initially stabilize the patient followed by gastric decompression. Surgical procedure comprises of gastric derotation followed by partial gastrectomy or spleenectomy depending upon gastric or spleenic viability and lastly, permanent right sided gastropexy. Post surgical considerations include frequent small meals instead of one large meal, avoiding vigorous activity immediately after meals and not allowing animal to gorge on water after meals or activities.

    Gastric dilatation-volvulus (GDV) is a disease in which there is gross distension of the stomach with fluid or gas and gastric malpositioning. It causes pathology of multiple organ systems and is rapidly fatal. It is common in large- and giant-breed dogs. The disease appears to have a familial predisposition. Thoracic depth/width ratio also appears to predispose dogs to GDV. Implicated dietary factors include dietary particle size, frequency of feeding, speed of eating, aerophagia and an elevated feed bowl. A fearful temperament and stressful events may also predispose dogs to GDV. Abdominal distension, non-productive retching, restlessness, signs of shock, tachypnoea and dyspnoea are possible clinical signs. Initial treatment includes treatment of shock and gastric decompression. Surgical treatment should be performed promptly. There are no studies comparing the use of different anaesthetic agents in the anaesthetic management of GDV. Pre-medication with an opioid/benzodiazepine combination has been recommended. Induction agents that cause minimal cardiovascular changes such as opioids, neuroactive steroidal agents and etomidate are recommended. Anaesthesia should be maintained with an inhalational agent. Surgical therapy involves decompression, correction of gastric malpositioning, debridement of necrotic tissue, and gastropexy. Options for gastropexy include incisional, tube, circumcostal, belt-loop, incorporating, and laparoscopic gastropexy. Expected mortality with surgical therapy is 15-24%. Prognostic factors include mental status on presentation, presence of gastric necrosis, presence of cardiac arrhythmia and plasma lactate levels. Prophylactic gastropexy should be considered in dogs identified as being at high risk.

    Obesity surgery includes various gastrointestinal procedures. Roux-en-Y gastric bypass is the prototype of mixed procedures being the most practiced worldwide. A similar and novel technique has been adopted by Dr. Almino Cardoso Ramos and Dr. Manoel Galvao called "simplified bypass," which has been accepted due to the greater ease and very similar results to the conventional technique. The aim of this study is to describe the results of the simplified gastric bypass for treatment of morbid obesity in our institution. We performed a descriptive, retrospective study of all patients undergoing simplified gastric bypass from January 2008 to July 2012 in the obesity clinic of a private hospital in Mexico City. A total of 90 patients diagnosed with morbid obesity underwent simplified gastric bypass. Complications occurred in 10% of patients; these were more frequent bleeding and internal hernia. Mortality in the study period was 0%. The average weight loss at 12 months was 72.7%. Simplified gastric bypass surgery is safe with good mid-term results and a loss of adequate weight in 71% of cases.

  6. Sox2 Suppresses Gastric Tumorigenesis in Mice

    2016-08-01

    Full Text Available Sox2 expression marks gastric stem and progenitor cells, raising important questions regarding the genes regulated by Sox2 and the role of Sox2 itself during stomach homeostasis and disease. By using ChIP-seq analysis, we have found that the majority of Sox2 targets in gastric epithelial cells are tissue specific and related to functions such as endoderm development, Wnt signaling, and gastric cancer. Unexpectedly, we found that Sox2 itself is dispensable for gastric stem cell and epithelial self-renewal, yet Sox2+ cells are highly susceptible to tumorigenesis in an Apc/Wnt-driven mouse model. Moreover, Sox2 loss enhances, rather than impairs, tumor formation in Apc-deficient gastric cells in vivo and in vitro by inducing Tcf/Lef-dependent transcription and upregulating intestinal metaplasia-associated genes, providing a mechanistic basis for the observed phenotype. Together, these data identify Sox2 as a context-dependent tumor suppressor protein that is dispensable for normal tissue regeneration but restrains stomach adenoma formation through modulation of Wnt-responsive and intestinal genes.

    Full Text Available Abstract Background Most of gastric adenocarcinoma can be simply diagnosed by microscopic examination of biopsy specimen. Rarely the structural and cellular atypia of tumor cells is too insignificant to discriminate from benign foveolar epithelium. Case presentation A 67-year-old male presented with a gastric mass incidentally found on the abdominal computed tomography (CT for routine medical examination. Gastric endoscopic examination revealed a huge fungating mass at the cardia and mucosal biopsy was performed. Microscopically the biopsy specimen showed proliferation of bland looking foveolar epithelia in the inflammatory background and diagnosed as foveolar epithelial hyperplasia. Because the clinical and endoscopic features of this patient were strongly suggestive of malignancy, the patient underwent radical total gastrectomy. The resected stomach revealed a huge fungating tumor at the cardia. The cut surface of the tumor was whitish gelatinous. Microscopically the tumor was sharply demarcated from surrounding mucosa and composed of very well formed glandular structures without significant cellular atypia, which invaded into the whole layer of the gastric wall. Tumor glands were occasionally complicated or dilated, and glandular lumina were filled with abundant mucin. Immunohistochemically the tumor cells revealed no overexpression of p53 protein but high Ki-67 labeling index. The tumor cells and intraluminal mucin were diffusely expressed MUC1 and MUC5AC and only focally expressed MUC2. On abdominal CT taken after 12 months demonstrated peritoneal carcinomatosis and multiple metastatic foci in the lung. Conclusion The clinicopathologic profiles of gastric extremely well differentiated adenocarcinoma of gastric phenotype include cardiac location, fungating gross type, very similar histology to foveolar epithelial hyperplasia, foveolar mucin phenotype, lack of p53 overexpressoin and high proliferative index.

    Endoscopic placement of self-expandable metallic stents is reportedly effective for gastric outlet obstructions due to advanced gastric cancer, and is less invasive than gastrojejunostomy. For patients who have good performance status, we administer chemotherapy after stent placement, although the safety and feasibility of this chemotherapy have not yet been discussed in full. Between 2011 and 2015, 15 patients at our institution underwent endoscopic gastroduodenal stent placement for gastric outlet obstruction due to gastric cancer. Eleven of these patients were administered chemotherapy after stent placement. In our case series, we did not observe any specific adverse event caused by stent placement plus chemotherapy. Adverse events after chemotherapy included anemia of CTCAE Grade 3 in 7 patients. Stent-in-stent placement was needed in 2 patients. Neither stent migration nor perforation was observed. Therefore, chemotherapy after stent placement for gastric outlet obstruction due to gastric cancer was considered safe and feasible. Stent placement is useful not only as palliative care for patients with terminal-stage disease, but also as one of the multimodal therapeutic strategies for gastric cancer.

    Full Text Available Background. Recently, endoscopic submucosal dissection (ESD has become a standard treatment method for early gastric cancer and concurrent stomach preservation. However, metachronous recurrences have become a major problem. We evaluated the incidence and clinicopathologic features of and examined the risk factors for metachronous gastric tumors. Methods. A total of 357 patients who underwent ESD for gastric tumors (245 early gastric cancers and 112 adenomas and were followed up for more than 12 months without recurrence within the first 12 months were enrolled. We investigated the incidence and clinicopathologic features of metachronous tumors after ESD. We also analyzed the potential risk factors for metachronous tumors using the Kaplan-Meier method and Cox’s proportional hazards model. Results. The annual incidence of metachronous tumors after ESD was 2.4%. The median period until discovery after initial ESD was 26.0 months, and the median observation period was 52.6 months. Male patients developed metachronous tumors more frequently (P=0.04, and the hazard ratio of female to male patients was 0.36 (95% confidence interval: 0.11–0.89. Conclusions. Patients with a previous history of gastric tumors have a high risk of subsequent gastric tumor development and male patients should be carefully followed up after ESD for gastric tumor.

    Full Text Available Abstract Background Overall gastric cancer survival remains poor mainly because there are no reliable methods for identifying highly curable early stage disease. Multi-protein profiling of gastric fluids, obtained from the anatomic site of pathology, could reveal diagnostic proteomic fingerprints. Methods Protein profiles were generated from gastric fluid samples of 19 gastric cancer and 36 benign gastritides patients undergoing elective, clinically-indicated gastroscopy using surface-enhanced laser desorption/ionization time-of-flight mass spectrometry on multiple ProteinChip arrays. Proteomic features were compared by significance analysis of microarray algorithm and two-way hierarchical clustering. A second blinded sample set (24 gastric cancers and 29 clinically benign gastritides was used for validation. Results By significance analysyis of microarray, 60 proteomic features were up-regulated and 46 were down-regulated in gastric cancer samples (p Conclusion This simple and reproducible multimarker proteomic assay could supplement clinical gastroscopic evaluation of symptomatic patients to enhance diagnostic accuracy for gastric cancer and pre-malignant lesions.

    Objective: To measure and define the distribution of left gastric lymph nodes. Methods: From Jan. 2004 to Apr. 2005, silver clips were set around the root of the left gastric artery in 124 patients with esophageal and gastric cardia carcinoma, X-ray films at 0 degree and 90 degree simulator gantry in the radio- therapeutic position were taken. Then, the data of the superior, lower, left, right, anterior and posterior bor- der in each patient was recorded. With SAS 8.02 software, data of minimum area which covered the left gastric lymph node in different incidences were obtained. Results: According to the analysis of Shapiro-Wilk, Kolmogorov-Smimov, Cramervon Mises and Anderson-Darling tests, each border' was of normal distribution, with equal frequency in the male and female, despite the actual results in different genders. Pearson Correlation Coefficients analysis did not suggest a significant relationship between the border and height, weight and size of vertebrae, which formed the minimum area covering the left gastric area at frequency of 100%, 95%, 90% and 85%, which were drawn out through the calculation. Conclusions: Aiming at completely identifying the normal distribution of the left gastric lymph node, more patients are required to be in the pool. For the time being, location in the left gastric area can be obtained from details of the results in the present study. (authors)

    Optimal endoscopic treatment of gastric varices is still not standardized nowadays. Actively bleeding varices may prohibit a successful endoscopic injection therapy of Histoacryl® (N-butyl-2-cyanoacrylate). Since 2006, we have treated gastric varices by standardized endoscopic ultrasound (EUS) guided Histoacryl injection therapy without severe adverse events. We present a large single-center cohort over 7 years with a standardized EUS-guided sclerotherapy of all patients with gastric varices. Application was controlled by fluoroscopy to immediately detect any glue embolization. Only perforating veins located within the gastric wall were treated. In the follow up, we repeated this treatment until varices were eradicated. Utmost patients (36 of 40) were treated during or within 24 h of active bleeding. About 32.5% of patients were treated while visible bleeding. Histoacryl injection was always technically successful and only two patients suffered a minor complication. Acute bleeding was stopped in all patients. About 15% (6 of 40) of patients needed an alternative rescue treatment in the longer course. Three patients got a transjugular portosystemic shunt and another three underwent an orthotopic liver transplantation. Mean long-term survival of 60 months was excellent. Active bleeding of gastric varices can be treated successfully without the necessity of gastric rinsing with EUS-guided injection of Histoacryl.

    Symptoms of patients with autoimmune gastritis are not specific, and some patients may present symptoms suggestive of delayed gastric emptying. This study aims to investigate whether any delay in gastric emptying of solid food exists in patients with autoimmune gastritis and, if so, to identify the factors that might affect delayed gastric emptying. A total of 165 patients (106 women) diagnosed as having autoimmune gastritis were analyzed by means of a gastric emptying test. All patients underwent a standardized scintigraphic gastric emptying study. Patients with delayed gastric emptying and normal gastric emptying tests were then compared by means of factors that might affect gastric emptying. Also 65 patients with functional dyspepsia who had a gastric emptying study constituted the control group. The median gastric emptying T ½ time was 127.43 min (min-max 50-953) for patients with AIG and 81 min (min-max 21-121.6) for functional dyspepsia patients (p gastritis, gastric emptying is generally delayed. Autoimmune gastritis is an important etiology to explain the finding of delayed gastric emptying on a radionuclide test. This new finding is likely to be relevant to clinicians when evaluating and initiating appropriate medical treatment for patients with autoimmune gastritis manifesting upper gastrointestinal symptoms.

    The aim of this study was to determine the antiulcer and antioxidant activities of Centaurium erythraea L (small centaury) in aspirin (ASA) induced acute gastric ulcer model. The gastroprotective effect of the 50% aqueous-ethanolic small centaury (SC) extract was investigated in rats at a dose of ASA 200 mg/kg body weight. Twenty-one Sprague-Dawley albino rats were divided into three groups of seven rats each as follows: (1) control group; (2) acute ASA-treated group and (3) ASA plus SC group. At the end of the 4-h drug administration, ulcer index, oxidant and antioxidant levels were measured and compared between the groups. The percentage of lesion area to total gastric surface area (ulcer index) was significantly reduced (77%) in ASA plus SC group as compared with acute ASA-treated group. The oral administration of ASA decreased catalase (CAT), reduced glutathione (GSH), and increased lipid peroxidation (LPO) levels. Although myeloperoxidase (MPO) activity was increased by ASA, it was found to be lower in the ASA plus SC group. GSH and Vitamin A levels were determined higher in the ASA plus SC group compared with ASA group. These results suggest that SC extract protects against ASA-induced damage due to its antioxidizing activity.

    This is the first report of anisakiasis in a Croatian patient, evidenced from an archival paraffin-embedded and hematoxylin-eosin stained tissue section. Anisakiasis has been only suspected in the country based on previously detected anti-Anisakis IgE seroprevalence in the healthy coastal population, as well as an acute case where pathohistological and serological findings suggested the diseases, but the migrating larva has not been retrieved. Seventy years-old female, operated in 1998 for pulmonary carcinoma, was admitted to the General hospital Šibenik, Croatia in 2003, because of gastric pain and nausea that lasted for couple of days. She was showing good general condition, full mobility and lucidity, subfebrile status. Abdominal palpation inferred acute pain in paraumbilical and ileocecal region. Exploratory right pararectal laparotomy revealed a hardened, 5 cm-long structure, located intraluminally in the sigmoid colon, not perforating colon serosa. The process has been dissected and sent for patohistological diagnosis. Results showed a 2 mm-long whitish nematode spiralised in muscular layer of colon mucosa surrounded by granulomatous inflammation. After genomic DNA isolation of the nematode from the histological section, and amplification at the mitochondrial cytochrome oxidase 2 locus, etiological agent has been identified as Anisakis pegreffii. Used methodology suggests that screening of archival suspicious sections is feasible in order to study epidemiology of this zoonotic disease poorly recognised in Croatia.

    Full Text Available The effect of H. pylori eradication in gastric cancer prevention can be attributed to the improvement of atrophic gastritis, which is a known risk of gastric cancer. However, gastric cancer has also been diagnosed after long-term H. pylori eradication. This study aimed to clarify the association between gastric atrophy and gastric cancer after H. pylori eradication, including its clinicopathological features.A total of 55 consecutive patients with 64 early gastric cancers (EGCs diagnosed after H. pylori eradication were enrolled. The degree of endoscopic atrophy and the histological degrees of mononuclear cell infiltration, atrophy, and metaplasia in the corpus and adjacent mucosa of the EGCs were determined and scored.The majority of EGCs (63/64 were located within the endoscopically assessed atrophic mucosa or along the atrophic border. The adjacent mucosa of the EGCs presented significantly higher degrees of all histological parameters than in the corpus (mononuclear cell infiltration, 0.86+/-0.09 vs. 0.51+/-0.11, P = 0.016; atrophy, 1.77+/-0.13 vs. 0.65+/-0.14, P<0.0001; metaplasia, 1.68+/-0.13 vs. 0.48+/-0.1, P<0.0001. The degree of endoscopic atrophy improved in the patients with longer post-H. pylori eradication periods; however, this trend was not observed for the histological parameters, and high degrees of atrophy and metaplasia were observed in the adjacent mucosa of the EGCs compared with the corpus during all periods (all P<0.05. The histological degrees of atrophy and metaplasia in the adjacent mucosa were particularly higher in the patients who underwent eradication due to gastric ulcers.Severe gastric atrophy remained in the adjacent mucosa of the EGCs after H. pylori eradication, which may be linked to gastric carcinogenesis.

    Gastric intestinal metaplasia, an intermediate lesion in the development of intestinal-type gastric cancer, is observed in the milieu of long standing non-atrophic gastritis and atrophic gastritis. Most patients with intestinal metaplasia remain asymptomatic unless cobalamin deficiency occurs secondary to loss of glands (that produce intrinsic factor and acid). Genetic events that predispose to development of gastric intestinal metaplasia remains an enigma. Mechanisms leading to the progression of atrophy to metaplasia still needs to be comprehensively explored. Many studies in the literature describe a positive effect of typing intestinal metaplasia and concluded that intestinal metaplasia type III carries the highest risk for developing gastric cancer while others refute it. It is well established that Helicobacter pylori infection is the most important factor for the development of chronic gastritis, gastric intestinal metaplasia as well as gastric cancer. Countries with a higher prevalence of Helicobacter pylori infection and gastric cancer also have a high tendency of being prevalent for intestinal metaplasia. However, it remains elusive whether eradication of Helicobacter pylori infection tends to regress gastric intestinal metaplasia or reduce the subsequent risk of cancer development. Putting together, more prospective cohort studies should be designed to identify factors (antioxidants; anti-inflammatory drugs; food therapy) that may contribute in the regression of intestinal metaplasia, when used simultaneously with eradication therapy. Furthermore, molecular markers for evaluation of intestinal metaplasia, and the potential point-of-no-return should be further investigated. Consensus is also required to advocate a timeframe for surveillance of patients with gastric intestinal metaplasia. (author)

    AIM: To investigate the characteristics of gastric cancer and gastric mucosa in a Mongolian population by comparison with a Japanese population. METHODS: A total of 484 Mongolian patients with gastric cancer were enrolled to study gastric cancer characteristics in Mongolians. In addition, a total of 208 Mongolian and 3205 Japanese consecutive outpatients who underwent endoscopy, had abdominal complaints, no history of gastric operation or Helicobacter pylori eradication treatment, and no use of gastric secretion inhibitors such as histamine H2-receptor antagonists or proton pump inhibitors were enrolled. This study was conducted with the approval of the ethics committees of all hospitals. The triple-site biopsy method was used for the histologic diagnosis of gastritis and H. pylori infection in all Mongolian and Japanese cases. The infection rate of H. pylori and the status of gastric mucosa in H. pylori-infected patients were compared between Mongolian and Japanese subjects. Age (± 5 years), sex, and endoscopic diagnosis were matched between the two countries. RESULTS: Approximately 70% of Mongolian patients with gastric cancer were 50-79 years of age, and approximately half of the cancers were located in the upper part of the stomach. Histologically, 65.7% of early cancers exhibited differentiated adenocarcinoma, whereas 73.9% of advanced cancers displayed undifferentiated adenocarcinoma. The infection rate of H. pylori was higher in Mongolian than Japanese patients (75.9% vs 48.3%, P gastritis changed from antrum-predominant gastritis to corpus-predominant gastritis with age in both populations. CONCLUSION: Gastric cancer was located in the upper part of the stomach in half of the Mongolian patients; Mongolian patients were infected with non-East-Asian-type H. pylori. PMID:26217093

    Laparoscopic gastric devascularization(Lap GDS) and splenectomy (SPL) for gastric varices is technically challenging because of highly developed collateral vessels and bleeding tendency. We investigated the feasibility of customization of Lap GDS and SPL based on CT vascular anatomy. We analyzed 61 cirrhotic patients with gastric varices who underwent Lap GDS and SPL between 2006 and 2014. Lap GDS was customized according to the afferent feeding veins (left gastric vein (LGV) and/or posterior gastric vein (PGV)/short gastric vein (SGV)) and efferent drainage veins (gastrorenal shunt and/or gastrophrenic shunt, or numerous retroperitoneal veins) based on CT imaging. Thirty-four patients with efferent drainage veins suitable for balloon-occluded retrograde transvenous obliteration (B-RTO) underwent B-RTO instead of surgical GDS, with subsequent Lap SPL. Among 27 patients with gastric varices unsuitable for B-RTO, 15 patients with PGV/SGV underwent Lap GDS of the greater curvature and SPL, and 12 patients with LGV or LGV/PGV/SGV underwent Lap GDS of the greater and lesser curvature and SPL. The mean operation time was 294 min and mean blood loss was 198 g. There was no mortality or severe morbidity. Gastric varices were eradicated in all 61 patients, with no bleeding or recurrence during a mean follow-up of 55.9 months. The cumulative 3-, 5-, and 7-year survival rates were 92, 82, and 64%, respectively. Lap GDS and SPL customized based on CT vascular anatomy is a safe and effective procedure for treating gastric varices.

    To evaluate the gastric emptying time of pharmaceutical dosage forms in a clinical setting, a relatively simple dual-radionuclide technique was developed. Placebo tablets of six different combinations of shape and size were labeled with indium-111 DTPA and enteric coated. Six volunteers participated in a single-blind and crossover study. Tablets were given in the morning of a fasting stomach with 6 oz of water containing /sup 99m/Tc pertechnetate and continuously observed with a gamma camera. A scintigraph was obtained each minute. The results suggested that the size, shape, or volume of the tablet used in this study had no significant effect in the rate of gastric emptying. The tablets emptied erratically and unpredictably, depending upon their time of arrival in the stomach in relation to the occurrence of interdigestive myoelectric contractions. The method described is a relatively simple and accurate technique to allow one to follow the gastric emptying of tablets

    It is well known that gastric ulcers are most often found at anglus and upper corpus in the elderly. The number of gastric ulcer found at upper corpus hold half of all cases in the elderly patients with bleeding ulcer. Sixty percent of the elderly patients with bleeding ulcer took NSAIDs including low-dose aspirin in authors' hospital. Now it is easy to treat and cure bleeding ulcers due to development of endoscopic hemostasis and antiulcer drugs such as proton pump inhibitor(PPI). However, the elderly patients sometimes result in fatal outcome on bleeding from gastric ulcer. Therefore, it is important to prevent ulcer complications by PPI for the high-risk group such as elderly patients taking NSAIDs.

  10. Is It Barrett's Esophagus or Gastric Heterotopia

    Full Text Available Columnar epithelium in the distal part of the esophagus is generally related to Barrett's esophagus. Barrett's esophagus is a well-known premalignant lesion for adenocarcinoma of the esophagus. Therefore, its diagnosis and surveillance are important. Columnar epithelium in the esophagus other than Barrett's esophagus can be gastric heterotopia, which generally takes place in the upper part of the esophagus and is named inlet patch. The presence of gastric metaplasia in the distal part of the esophagus is rare and can cause misdiagnosis. Therefore, its differentiation from Barrett's esophagus is important. Here we present a case of gastric heterotopia located in the distal part of the esophagus that caused reflux-like symptoms and needed differentiation from Barrett's esophagus.

    Both sodium selenite and selenium yeast were chosen to block the MNNG mutagenesis. The inhibition rates were 66.5% and 37.9% respectively. The selenium levels in hair, serum and gastric juice, and the contents of nitrosamine in gastric juice were also determined. The results showed that the selenium levels were SG > CAG and Dys > GC (p CAG, Dyas and GC (p < 0.05). 19 cases of CAG patients treated with selenium yeast and 16 cases of the control were observed. After 10 weeks, the selenium levels in serum for the treated group were significantly increased. The symptoms of CAG patients seemed to be alleviated

    Full Text Available Osteogenesis imperfecta (OI is a rare, inherited skeletal disorder characterized by abnormalities of type 1 collagen. Malignancy is rarely reported in patients with OI and it was suggested that this disease can protect against cancer. Here, we report a 41-year-old woman with symptoms of achalasia where repeated treatment of pneumatic dilation and stent replacement was unsuccessful; therefore, surgery was performed. Pathology showed gastric adenocarcinoma unexpectedly. Chemotherapy was given after assessing dihydropyrimidine dehydrogenase (DPD enzyme activity, which can be deficient in OI patients. This is the first report of gastric cancer mimicking achalasia in a patient with OI.

    Equine gastric ulcer syndrome (EGUS) is an umbrella term used to describe ulcers in the nonglandular squamous and glandular mucosa, terminal esophagus, and proximal duodenum. Gastric ulcers in the squamous and glandular regions occur more often than esophageal or duodenal ulcers and likely have a different pathogenesis. At present, omeprazole is accepted globally as the best pharmacologic therapy for both regions of the stomach; however, the addition of coating agents and synthetic prostaglandins could add to its effectiveness in treatment of EGUS. Dietary and environmental management are necessary for prevention of recurrence. Copyright © 2016 Elsevier Inc. All rights reserved.

    Between 2000 and 2007, 17 patients with localized gastric lymphoma (10 mucosa-associated lymphoid tissue lymphomas and 7 diffuse large B-cell lymphomas) were treated with radiotherapy alone or doxorubicin-based chemotherapy followed by radiotherapy. Radiation dose of mucosa-associated lymphoid tissue (MALT) lymphoma was 30 Gy with a daily fraction size of 1.5 Gy. Sixteen patients achieved complete remission and the 5-year overall survival of MALT lymphoma and diffuse large B-cell lymphoma (DLBCL) were 100% and 87%, respectively. No gastric perforation and hemorrhage were noticed. Using AP/LR 2-port radiotherapy markedly decreased the liver dose. (author)

  16. Acute poisoning with emamectin benzoate.

    Emamectin benzoate is the 4'-deoxy-4'-epi-methyl-amino benzoate salt of avermectin B1 (abamectin), which is similar structurally to natural fermentation products of Streptomyces avermitilis. Emamectin benzoate is being developed as a newer broad-spectrum insecticide for vegetables and has a very low application rate. The mechanism of action involves stimulation of high-affinity GABA receptors and a consequent increase in membrane chloride ion permeability. Animal studies indicate a wide margin of safety because mammalian species are much less sensitive due to lower GABA receptor affinities and relative impermeability of the blood-brain barrier. Notably, the literature has not reported human exposure resulting in toxicity. This paper describes a case of acute poisoning with Proclaim insecticide (Syngenta, Taiwan), consisting of 2.15% w/w emamectin benzoate in 2, 6-bis (1, 1-dimethylethyl)-4-methyl-phenol and 1-hexanol. The clinical manifestation was transient gastrointestinal upset with endoscopy-proven gastric erosion and superficial gastritis, mild central nervous system depression, and aspiration pneumonia. No specific antidote exists for emamectin benzoate intoxication; this patient was treated successfully with gastric lavage, administration of activated charcoal, and empiric antibiotics. Drugs that enhance GABA activity such as barbiturates and benzodiazepines were avoided.

    Full Text Available Diaphragmatic hernia may be congenital or traumatic in origin. Diaphragmatic hernias are more common in adult and occur as a result of penetrating injuries are more common than from blunt injuries. Traumatic diaphragmatic hernia may manifest immediately or without any findings that several months/years after the incident. Early diagnosis is difficult, and it is usually made intraoperatively. Frequently during the early phase of traumatic diaphragmatic hernias, abdominal organ injury can be seen, such as stomach, colon and liver. In this study, we presented a case with acute gastric strangulation and perforation in the diaphragmatic injury occurred as a result of penetrating thoracic trauma.

    Full Text Available Gastric volvulus is a rare medical entity that requires high index of suspicion for diagnosis and treatment as it has different implications in terms of clinical presentation, diagnosis, imaging support, pathological behavior, and evaluation. When it presents acutely, it may be easily detected. However, in patients with subacute presentation, symptoms are vague due to episodic twisting and untwisting. Definite preoperative diagnosis can be established if imaging is performed during symptomatic interval. The main aim of this report was to stress on the need for keeping high index of suspicion for this medical condition and for imaging the patient during symptomatic interval.

    2012-01-01

    Full Text Available This paper, based on relevant literature articles and the authors' clinical experience, presents a goal-oriented respiratory management for critically ill patients with acute respiratory distress syndrome (ARDS that can help improve clinicians' ability to care for these patients. Early recognition of ARDS modified risk factors and avoidance of aggravating factors during hospital stay such as nonprotective mechanical ventilation, multiple blood products transfusions, positive fluid balance, ventilator-associated pneumonia, and gastric aspiration can help decrease its incidence. An early extensive clinical, laboratory, and imaging evaluation of “at risk patients” allows a correct diagnosis of ARDS, assessment of comorbidities, and calculation of prognostic indices, so that a careful treatment can be planned. Rapid administration of antibiotics and resuscitative measures in case of sepsis and septic shock associated with protective ventilatory strategies and early short-term paralysis associated with differential ventilatory techniques (recruitment maneuvers with adequate positive end-expiratory pressure titration, prone position, and new extracorporeal membrane oxygenation techniques in severe ARDS can help improve its prognosis. Revaluation of ARDS patients on the third day of evolution (Sequential Organ Failure Assessment (SOFA, biomarkers and response to infection therapy allows changes in the initial treatment plans and can help decrease ARDS mortality.

    2013-10-01

    Acute upper gastrointestinal bleeding (UGIB) is the most common reason that the 'on-call' gastroenterologist is consulted. Despite the diagnostic and therapeutic capabilities of upper endoscopy, there is still significant associated morbidity and mortality in patients experiencing acute UGIB, thus this is a true GI emergency. Acute UGIB is divided into non-variceal and variceal causes. The most common type of acute UGIB is 'non-variceal' and includes diagnoses such as peptic ulcer (gastric and duodenal), gastroduodenal erosions, Mallory-Weiss tears, erosive oesophagitis, arterio-venous malformations, Dieulafoy's lesion, and upper GI tract tumours and malignancies. This article focuses exclusively on initial management strategies for acute upper GI bleeding. We discuss up to date and evidence-based strategies for patient risk stratification, initial patient management prior to endoscopy, potential causes of UGIB, role of proton pump inhibitors, prokinetic agents, prophylactic antibiotics, vasoactive pharmacotherapies, and timing of endoscopy.
