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 < 0.0001). When stratified by age, the prevalence was highest among young patients, and tended to decrease in patients aged 50 years or older. The anti-East-Asian CagA-specific antibody was negative in 99.4% of H. pylori-positive Mongolian patients. Chronic inflammation, neutrophil activity, glandular atrophy, and intestinal metaplasia scores were significantly lower in Mongolian compared to Japanese H. pylori-positive patients (P < 0.0001), with the exception of the intestinal metaplasia score of specimen from the greater curvature of the upper body. The type of 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

Cases of primary gastric adenocarcinoma with metastasis to the breast are extremely rare. Till now, only 38 cases have been reported in PubMed since 1908. We herein reported a race case of gastric adenocarcinoma with metastasis to the right breast. Breast biopsy showed invasive signet-ring cell breast carcinoma in the right breast. She was given a TEC regimen (docetaxel 75 mg/m(2), epirubicin 75 mg/m(2), and cyclophosphamide 600 mg/m(2) every 3 weeks) for one cycle but showed no objective response. Upper gastrointestinal endoscopy demonstrated an ulcerative mass in the gastric body. Biopsy demonstrated low-grade gastric adenocarcinoma with signet-ring features. In immunohistochemistry, mammary malignant cells were positive for cytokeratin 7, cytokeratin 20, villin, and ErbB2/HER2, but negative for gross cystic disease fluid protein-15, estrogen receptor, and progesterone receptor. The diagnosis of metastatic poorly differentiated signet-ring cell adenocarcinoma of the right breast identical to gastric primary was confirmed finally. Gastric cancer with metastasis to the breast can be diagnosed by clinical history, histological findings, and immunohistochemical markers.

In the present paper, we report a case of rare collagenous gastritis. The patient was a 25-year-old man who had experienced nausea, abdominal distention and epigastralgia since 2005. Esophagogastroduodenoscopy (EGD) carried out at initial examination by the patient's local doctor revealed an extensively discolored depression from the upper gastric body to the lower gastric body, mainly including the greater curvature, accompanied by residual mucosa with multiple islands and nodularity with a cobblestone appearance. Initial biopsies sampled from the nodules and accompanying atrophic mucosa were diagnosed as chronic gastritis. In August, 2011, the patient was referred to Tohoku University Hospital for observation and treatment. EGD at our hospital showed the same findings as those by the patient's local doctor. Pathological findings included a membranous collagen band in the superficial layer area of the gastric mucosa, which led to a diagnosis of collagenous gastritis. Collagenous gastritis is an extremely rare disease, but it is important to recognize its characteristic endoscopic findings to make a diagnosis. © 2012 The Authors.

(99m) Technetium scintigraphy ((99m) TS) is the 'gold standard' for measuring gastric emptying (GE), but it is associated with a radiation exposure. For this reason, the (13) C-octanoic acid breath test ((13) C-OBT) was developed for measuring GE of solids. The objective of this study was to determine normal values for gastric half-emptying time (t1/2 GE) of solids in healthy children. Gastric emptying of a standardized solid test meal consisting of a pancake evaluated with (99m) TS and (13) C-OBT was compared in 22 children aged between 1 and 15 years with upper gastrointestinal symptoms. Subsequently, the (13) C-OBT was used to determine normal values for GE of the same solid test meal in 120 healthy children aged between 1 and 17 years. The results showed a significant correlation (r = 0.748, p = 0.0001) between t1/2 GE measured with both techniques in the group of children with upper gastrointestinal symptoms. In the group of healthy children, mean t1/2 GE was 157.7 ± 54.0 min (range 71-415 min), but t1/2 GE decreased with age between 1 and 10 years and remained stable afterward. There was no influence of gender, weight, height, body mass index, and body surface area on t1/2 GE. Normal values for GE of solids measured with the (13) C-OBT using a standardized methodology were determined in healthy children. We propose to use this method and corresponding reference ranges to study GE of solids in children with gastrointestinal problems. © 2016 John Wiley & Sons Ltd.

To examine the effect of intra-gastric triacetin on both upper gastrointestinal motility and proximal gastric tone in conscious dogs. Three beagle dogs under sedation were surgically implanted with gastrocutaneous fistula in the gastric body and force transducers in the gastric antrum and duodenum. Beginning at week-2 after insertion, the animals were either fasted for 24 h or fed a liquid meal 2-3 h before the experiment. With the animals fully conscious, a polyethylene bag was inserted into the proximal stomach through the gastrocutaneous fistula, followed by 15 min of air inflation (minimal distending pressure of ＋2 mmHg) and then 20 mL of a low-, mid- or high-concentration triacetin solution (0.5%, 1.0% and 2.0%) or warm water (vehicle control). The proximal stomach receptive volume and gastric antral and duodenal contractions were measured over 10 min. The experiment was repeated twice per week over several months, with each animal receiving at least one infusion of the various triacetin solutions and the vehicle at different times. Intergroup differences were assessed by ANOVA and Bonferroni-Dunn post-hoc testing. Intra-gastric infusion of mid- and high-concentration triacetin induced an increase in the proximal stomach receptive volume, and the average increase induced by the high-concentration at 0-4 min after infusion was significantly greater than that induced by the vehicle control (62.4 ± 9.8 vs 18.4 ± 4.7, P < 0.01). The mid- and high-concentration triacetin also produced a temporary inhibition of the gastric antral contractions at 2 min after infusions; however, only the fasted group showed triacetin-induced antral contractile inhibition that was significantly greater than that in the vehicle control group (P < 0.05). In addition, only the fasted group showed a high-concentration triacetin-induced increase in duodenal contractions at 9-10 min that was significantly different from that in the vehicle control group (P < 0.05). Intra-gastric infusion of 1.0%-2.0% triacetin delays gastric emptying by increasing proximal stomach receptive volume, temporarily inhibiting gastric antral contractions and facilitating duodenal contractions.

RM-131, a synthetic ghrelin agonist, greatly accelerates gastric emptying of solids in patients with type 2 diabetes and delayed gastric emptying (DGE). We investigated the safety and effects of a single dose of RM-131 on gastric emptying and upper gastrointestinal (GI) symptoms in patients with type 1 diabetes and previously documented DGE. In a double-blind cross-over study, 10 patients with type 1 diabetes (age, 45.7 ± 4.4 y; body mass index, 24.1 ± 1.1 kg/m(2)) and previously documented DGE were assigned in random order to receive a single dose of RM-131 (100 μg, subcutaneously) or placebo. Thirty minutes later, they ate a radiolabeled solid-liquid meal containing EggBeaters (ConAgra Foods, Omaha, NE), and then underwent 4 hours of gastric emptying and 6 hours of colonic filling analyses by scintigraphy. Upper GI symptoms were assessed using a daily diary, gastroparesis cardinal symptom index (total GCSI-DD) and a combination of nausea, vomiting, fullness, and pain (NVFP) scores (each rated on a 0-5 scale). At screening, participants' mean level of hemoglobin A1c was 9.1% ± 0.5%; their total GCSI-DD score was 1.66 ± 0.38 (median, 1.71), and their total NVFP score was 1.73 ± 0.39 (median, 1.9). The t1/2 of solid gastric emptying was 84.9 ± 31.6 minutes when subjects were given RM-131 and 118.7 ± 26.7 when they were given a placebo. The median difference (Δ)was 33.9 minutes (interquartile range [IQR] -12, -49), or -54.7% (IQR, -21%,-110%). RM-131 decreased gastric retention of solids at 1 hour (P = .005) and 2 hours (P = .019). Numeric differences in t1/2 for gastric emptying of liquids, solid gastric emptying lag time, and colonic filling at 6 hours were not significant. Total GCSI-DD scores were 0.79 on placebo (IQR, 0.75, 2.08) and 0.17 on RM-131 (IQR, 0.00, 0.67; P = .026); NVFP scores were lower on RM-131 (P = .041). There were no significant adverse effects. RM-131 significantly accelerates gastric emptying of solids and reduces upper GI symptoms in patients with type 1 diabetes and documented DGE. Copyright © 2013 AGA Institute.

There have been no reports of primary leiomyosarcoma of the stomach treated by endoscopic submucosal dissection (ESD). We report an extremely rare case of gastric leiomyosarcoma that was successfully treated by ESD. An asymptomatic 74-year-old female underwent esophagogastroduodenoscopy for screening in December 2013. A centrally depressed submucosal tumor 10 mm in diameter was detected at the posterior wall of the upper gastric body. Follow-up esophagogastroduodenoscopy conducted 5 months later showed that the tumor diameter had increased to 15 mm. Endoscopic ultrasound revealed a hypoechoic mass located in the second to the middle of the third layer. Endoscopic ultrasound-guided fine-needle aspiration demonstrated a myogenic tumor. The tumor was completely resected by ESD without complications. Immunohistopathological diagnosis of the resected specimen was gastric leiomyosarcoma derived from the muscularis mucosae, with negative lateral and vertical margins. No local recurrence or metastasis has been detected at 36 months after ESD. This is the first report of gastric leiomyosarcoma treated by ESD in the English language literature.

Studies describing the prevalence of upper gastrointestinal (GI) Crohn disease (CD) and its histopathologic changes have been inconsistent as a result of different definitions used for upper GI involvement, diverse populations, and varying indications for endoscopy. We reviewed the literature describing endoscopic findings and histologic lesions in gastric and duodenal mucosa of patients with established CD. PubMed, EMBASE, and the Cochrane Library were searched for gastroduodenal biopsy findings in patients with CD from 1970 to 2014. We included all retrospective and prospective studies in adults. We calculated the prevalence of the most common endoscopic and histopathological findings among patients with overall CD and upper GI CD. Of the 385 articles identified, 20 eligible studies were included. A total of 2511 patients had CD and 815 had upper GI CD. In the CD group, the most common histopathological finding was nonspecific gastric inflammation in 32% of patients, followed by gastric granuloma in 7.9%. Focal gastritis was prevalent in 30.9% of patients. In the upper GI CD group, gastric inflammation was present in 84% of patients, followed by duodenal inflammation in 28.2% and gastric granuloma in 23.2%. The most common gastric endoscopic finding in patients with CD was erythema in 5.9%, followed by erosions in 3.7%. Duodenal endoscopic findings included ulcers and erythema in 5.3% and 3.0% of patients, respectively. We found a prevalence of 34% for CD involving the upper GI tract across these 20 studies. Routine upper endoscopy with biopsies of the upper GI tract in the diagnostic workup of patients with CD can correctly classify the distribution and extent of the disease.

Gastric surgery may potentiate delayed gastric emptying. Billroth I gastroduodenostomy using a circular stapler is the most preferable reconstruction method. The purpose of this study is to analyze the risk factors associated with delayed gastric emptying after radical subtotal gastrectomy with Billroth I anastomosis using a stapler for early gastric cancer. Three hundred and seventy-eight patients who underwent circular stapled Billroth I gastroduodenostomy after subtotal gastrectomy due to early gastric cancer were analyzed retrospectively. One hundred and eighty-two patients had Billroth I anastomosis using a 25 mm diameter circular stapler, and 196 patients had anastomosis with a 28 or 29 mm diameter circular stapler. Clinicopathological features and postoperative outcomes were evaluated and compared between the two groups. Delayed gastric emptying was diagnosed by symptoms and simple abdomen X-ray with or without upper gastrointestinal series or endoscopy. Postoperative delayed gastric emptying was found in 12 (3.2%) of the 378 patients. Among all the variables, distal margin and circular stapler diameter were significantly different between the cases with delayed gastric emptying and no delayed gastric emptying. There were statistically significant differences in sex, body mass index, comorbidity, complication, and operation type according to circular stapler diameter. In both univariate and multivariate logistic regression analyses, only the stapler diameter was found to be a significant factor affecting delayed gastric emptying (P = 0.040). In this study, the circular stapler diameter was one of the most significant predictable factors of delayed gastric emptying for Billroth I gastroduodenostomy. The use of a 28 or 29 mm diameter circular stapler rather than a 25 mm diameter stapler in stapled gastroduodenostomy for early gastric cancer can reduce postoperative delayed gastric emptying associated with anastomosic stenosis or edema with relative safety.

Our aim was to explore in children with functional dyspepsia the effect of hippophae rhamnoides on the levels of plasma appetite factors and on their gastrointestinal motility. A hundred and twenty children with functional dyspepsia were randomly divided into three groups: Group I (treated with hippophae rhamnoides), Group II (treated with domperidone), and Group III (treated with hippophae rhamnoides plus domperidone). The treatment lasted for eight weeks. The levels of plasma leptin (LP) and neuropeptide Y (NPY) were measured before and after treatment. All patients underwent a gastric emptying (GE) test by ultrasound (US) to measure the rate of postprandial gastric antrum residual, at 30min, 60min, 90min and 120min. The average value of subcutaneous fat, body fat percentage, upper arm girth and body mass index (BMI) were also measured. To compare the US with the radionuclide GE test 14 healthy adults volunteers were tested by both GE techniques. We found that the levels of LP and NPY in plasma were markedly higher after treatment in Groups I and III than in Group II. The postprandial gastric antrum remains at 60min, 90min and 120min in Groups I and III fell greatly and the thickness of skin fold (SF), body fat percentage and arm girth increased (P<0.05). The GE half emptying time of a mixed liquid-solid food measured by B US and by the radionuclide technique in the same individuals was similar (P>0.05). In conclusion, in children's functional dyspepsia, our study showed that hippophae rhamnoides increases the levels of appetite factors, leptin and neuropeptide Y, increases gastric emptying and gastrointestinal digestive function, children's growth and development.

BACKGROUND Many studies have reported an association between periodontal infections and some systemic diseases such as respiratory and cardiovascular diseases. Some studies found a direct association between chronic gastritis caused by Helicobacter pylori (HP) infection and poor periodontal health. METHODS In a cross-sectional study from November 2014 to December 2015 in Kerman, the largest province in southeast Iran, patients with dyspepsia who were candidate for diagnostic upper gastrointestinal (GI) endoscopy were included in our study. Decayed, Missing, and Filled Teeth (DMFT) index and Loe plaque index that are two popular indexes in dental epidemiology were used to assess the oral health by a dentist before the upper GI endoscopy. According to the Loe plaque index, score: 0= no plaque, score: 1= a film of plaque attaching to the free gingival border and near area of the tooth, score: 2= moderate reposition of deposits within the gingival pocket, score :3= plenty of soft matter within the gingival pocket±on the tooth and gingival border. Scores ≤1, 2 and 3 equal to good, moderate, and poor oral hygiene, respectively. During upper GI endoscopy a total of six biopsy samples were taken from fundus, body, and antrum. A pathologist reported these samples according to Sidney's classification into superficial gastritis, atrophic gastritis, intestinal metaplasia, and dysplasia. RESULTS According to Sidney's classification 77 (89.5%) patients had superficial gastritis, 3 (3.5%) had atrophic gastritis, and 6 (7%) had intestinal metaplasia. HP was found in 80.2% of the gastric mucosal biopsy samples. There were not statistically significant relationship between Sidney's classification, presence of HP in gastric mucosal biopsies, and hygiene indicators ( p >0.05). No relation was found between the DMFT index and superficial gastritis, atrophic gastritis, and intestinal metaplasia ( p >0.05). Gastric infection with HP was found in 70%, 75%, and 100% of patients with mild, moderate, and sever DMFT index, respectively. CONCLUSION Our study showed that there might be a relation between poor oral hygiene and gastric precancerous lesions. In addition, HP infection in gastric histopathology might be associated with periodontal disease.

Morbid obesity treatment through vertical gastroplasty Roux-en-Y gastric bypass initially used a contention ring. However, this technique may create conditions to the development of potentially malign alterations in the gastric mucosa. Although effective and previously performed in large scale, this technique needs to be better evaluated in long-term studies regarding alterations caused in the gastric mucosa. To analyze the preoperative and postoperative endoscopic, histological and cell proliferation findings in the gastric antrum and body mucosa of patients submitted to the Roux-en-Y gastric bypass with a contention ring. We retrospectively evaluated all patients submitted to Roux-en-Y gastric bypass with a contention ring with more than 60 months of postoperative follow-up. We compared the preoperative (gastric antrum and body) and postoperative (gastric pouch) gastric mucosa endoscopic findings, cell proliferation index and H. pylori prevalence. We evaluated cell proliferation through Ki-67 antibody immunohistochemical expression. In the study period, 33 patients were operated with the Roux-en-Y gastric bypass using a contention ring. We found a chronic gastritis rate of 69.7% in the preoperative period (gastric antrum and body) and 84.8% in the postoperative (gastric pouch). H. pylori was present in 18.2% of patients in the preoperative period (gastric antrum and body) and in 57.5% in the postoperative (gastric pouch). Preoperative cell proliferation index was 18.1% in the gastric antrum and 16.2% in the gastric body, and 23.8% in the postoperative gastric pouch. The postoperative cell proliferation index in the gastric pouch was significantly higher (P=0.001) than in the preoperative gastric antrum and body. Higher cell proliferation index and chronic gastritis intensity were significantly associated to H. pylori presence (P=0.001 and P=0.02, respectively). After Roux-en-Y gastric bypass with contention ring, there was a higher chronic gastritis incidence and higher cell proliferation index in the gastric pouch than in the preoperative gastric antrum and body. Mucosa inflammation intensity and cell proliferation index in the postoperative gastric pouch were associated to H. pylori presence and were higher than those found in the preoperative gastric antrum and body mucosa.

An 86-year-old man with dysphagia underwent gastrointestinal fiberscopy (GIF) and was found to have a circumferential type 3 advanced carcinoma in the upper thoracic esophagus and a type 2 tumor in the posterior wall of the gastric body. Microscopic examination of biopsy specimens of both tumors demonstrated moderately differentiated squamous cell carcinoma. He was diagnosed as having stage IVb (T3N0M1b) esophageal carcinoma with gastric wall metastasis. A total of 60 Gy in 30 fractions of three-dimensional conformal radiation therapy (3D-CRT) was first administered to the esophageal carcinoma, next to the gastric wall metastasis. Concurrent chemotherapy was not given because of the patient's refusal. No subjective morbidity was observed during the treatment. In the GIF study immediately after 3D-CRT, both esophageal and gastric wall tumors had attained a complete response. The dysphagia dissolved as the esophageal tumor shrunk. The patient has been doing well for 17 months after the start of 3D-CRT. No local recurrence was observed in either the esophagus or the stomach during follow-up GIF. Considering the dismal prognosis of esophageal carcinoma patients with intramural metastasis to the stomach, a watchful follow-up is needed.

Laparoscopy-assisted total gastrectomy (LATG) is commonly performed for early gastric cancer (EGC) in the upper stomach; however, the incidence of anastomotic complications remains high, and postoperative nutritional status is not satisfactory. This study aimed to evaluate the feasibility and nutritional impact of a novel surgical procedure, laparoscopy-assisted subtotal gastrectomy (LAsTG). This was a retrospective study of 167 patients with EGC in the upper stomach. Of these, 57 patients underwent LAsTG, while 110 patients underwent LATG. Postoperative change in body weight, and serum concentration of albumin (Alb) and total protein (TP) were compared between the LAsTG and LATG groups. Analysis of covariance (ANCOVA) was used to assess the influence of potential confounding factors. Frequency of anastomotic complications was significantly higher in the LATG group (16.3 %) than in the LAsTG group (5.3 %, P = 0.040). Postoperative recovery of body weight at 12 months after surgery was significantly better in the LAsTG group (89.8 ± 1.4 %) than in the LATG group (82.1 ± 1.0 %, P < 0.001). By ANCOVA, adjusted mean differences of Alb and TP at 12 months after surgery between the LAsTG and LATG groups were 0.226 g/dl (95 % CI 0.141-0.312; P < 0.001) and 0.380 g/dl (95 % CI 0.265-0.495; P < 0.001); thus, the surgical procedure was significantly associated with the postoperative Alb and TP levels. LAsTG could be a better choice than LATG for EGC in the upper stomach as a result of improvements in the incidence of anastomotic complications and postoperative nutritional status.

Roux-en-Y gastric bypass is a common surgical procedure used to treat patients with morbid obesity. One of the rare, but potentially fatal complications of gastric bypass is upper gastrointestinal bleeding, which can pose diagnostic and therapeutic dilemmas. This report describes a 39-year-old male with morbid obesity who underwent a Roux-en-Y gastric bypass. Three months postoperatively, he sustained repeated and severe upper attacks of upper gastrointestinal bleeding. He received multiple blood transfusions, and had repeated upper and lower endoscopies with no diagnostic yield. Finally, he underwent laparoscopic endoscopy which revealed a bleeding duodenal ulcer. About 5 ml of saline with adrenaline was injected, followed by electrocoagulation to seal the overlying cleft and blood vessel. He was also treated with a course of a proton pump inhibitor and given treatment for H pylori eradication with no further attacks of bleeding. Taking in consideration the difficulties in accessing the bypassed stomach endoscopically, laparoscopic endoscopy is a feasible and valuable diagnostic and therapeutic procedure in patients who had gastric bypass.

To propose media for simulating the intragastric environment under reduced gastric acid secretion in the fasted state at three levels of simulation of the gastric environment and evaluate their usefulness in evaluating the intragastric dissolution of salts of weak bases. To evaluate the importance of bicarbonate buffer in biorelevant in vitro dissolution testing when using Level II biorelevant media simulating the environment in the fasted upper small intestine, regardless of gastric acid secretions. Media for simulating the hypochlorhydric and achlorhydric conditions in stomach were proposed using phosphates, maleates and bicarbonates buffers. The impact of bicarbonates in Level II biorelevant media simulating the environment in upper small intestine was evaluated so that pH and bulk buffer capacity were maintained. Dissolution data were collected using two model compounds, pioglitazone hydrochloride and semifumarate cocrystal of Compound B, and the mini-paddle dissolution apparatus in biorelevant media and in human aspirates. Simulated gastric fluids proposed in this study were in line with pH, buffer capacity, pepsin content, total bile salt/lecithin content and osmolality of the fasted stomach under partial and under complete inhibition of gastric acid secretion. Fluids simulating the conditions under partial inhibition of acid secretion were useful in simulating concentrations of both model compounds in gastric aspirates. Bicarbonates in Level III biorelevant gastric media and in Level II biorelevant media simulating the composition in the upper intestinal lumen did not improve simulation of concentrations in human aspirates. Level III biorelevant media for simulating the intragastric environment under hypochlorhydric conditions were proposed and their usefulness in the evaluation of concentrations of two model salts of weak bases in gastric aspirates was shown. Level II biorelevant media for simulating the environment in upper intestinal lumen led to underestimation of concentrations in aspirates, even when bicarbonate buffer was used.

Upper gastrointestinal (GI) bleeding is a common medical emergency associated with significant morbidity and mortality. The clinical presentation depends on the amount and location of hemorrhage and the endoscopic profile varies according to different etiology. At present, there are limited epidemiological data on upper GI bleed and associated mortality from India, especially in the middle and elderly age group, which has a higher incidence and mortality from this disease. This study aims to study the clinical and endoscopic profile of middle aged and elderly patients suffering from upper GI bleed to know the etiology of the disease and outcome of the intervention. Out of a total of 1790 patients who presented to the hospital from May 2015 to August 2017 with upper GI bleed, and underwent upper GI endoscopy, data of 1270 patients, aged 40 years and above, was compiled and analyzed retrospectively. All the patients included in the study were above 40 years of age. Majority of the patients were males, with a male to female ratio of 1.6:1. The most common causes of upper GI bleed in these patients were portal hypertension-related (esophageal, gastric and duodenal varices, portal hypertensive gastropathy, and gastric antral vascular ectasia GAVE), seen in 53.62% of patients, followed by peptic ulcer disease (gastric and duodenal ulcers) seen in 17.56% of patients. Gastric erosions/gastritis accounted for 15.20%, and duodenal erosions were seen in 5.8% of upper GI bleeds. The in-hospital mortality rate in our study population was 5.83%. The present study reported portal hypertension as the most common cause of upper GI bleeding, while the most common endoscopic lesions reported were esophageal varices, followed by gastric erosion/gastritis, and duodenal ulcer.

Advances in Endoscopic submucosal dissection (ESD) technology have established ESD for early gastric cancer as a safe and stable technique. However, ESD may induce delayed gastric emptying and the cause of food residue retention in the stomach after ESD is not clear. This study aimed to clarify risk factors for delayed gastric emptying with food retention after gastric ESD. We retrospectively examined for food residue in the stomach 1 week after ESD was performed for early gastric carcinoma at Osaka Saiseikai Nakatsu Hospital from February 2008 to November 2016. Food residue was observed in 68 (6.1%) of 1114 patients who underwent gastric ESD. The percentage of lesions located on the lesser curvature of the upper third of the stomach was 45.6% (31/68) in the food residue group and 3.5% (37/1046) in the non-food residue group, which was significantly different (P < 0.01). Multivariate logistic regression analysis revealed that lesions on the lesser curvature of the upper third of the stomach (Odds ratio [OR] 23.31, 95% confidence interval [CI] 12.60-43.61, P < 0.01), post-ESD bleeding (OR 4.25, 95%CI 1.67-9.80, P < 0.01), submucosal invasion (OR 2.80, 95%CI 1.34-5.63, P < 0.01), and age over 80 years (OR 2.34, 95%CI 1.28-4.22, P < 0.01) were independent risk factors for food retention after gastric ESD. Of the 68 patients, 3 had food residue in the stomach on endoscopic examination for follow-up observation after the ESD ulcer had healed. Delayed gastric emptying with food retention after gastric ESD was associated with lesions located in the lesser curvature of the upper stomach, submucosal invasion of the lesion, age older than 80 years, and post-ESD bleeding, though it was temporary in most cases.

An association between Helicobacter pylori and upper respiratory tract disease: Fact or fiction?

PubMed Central

Kariya, Shin; Okano, Mitsuhiro; Nishizaki, Kazunori

Helicobacter pylori (H. pylori) is a major cause of chronic gastritis and gastric ulcers and considerable evidence supports the notion that infection with this bacterium is also associated with gastric malignancy in addition to various other conditions including pulmonary, vascular and autoimmune disorders. Gastric juice infected with H. pylori might play an important role in upper respiratory tract infection. Although direct and/or indirect mechanisms might be involved in the association between H. pylori and upper respiratory tract diseases, the etiological role of H. pylori in upper respiratory tract disorders has not yet been fully elucidated. Although various studies over the past two decades have suggested a relationship between H. pylori and upper respiratory tract diseases, the findings are inconsistent. The present overview describes the outcomes of recent investigations into the impact of H. pylori on upper respiratory tract and adjacent lesions. PMID:24587622

Purpose Gastric surgery may potentiate delayed gastric emptying. Billroth I gastroduodenostomy using a circular stapler is the most preferable reconstruction method. The purpose of this study is to analyze the risk factors associated with delayed gastric emptying after radical subtotal gastrectomy with Billroth I anastomosis using a stapler for early gastric cancer. Methods Three hundred and seventy-eight patients who underwent circular stapled Billroth I gastroduodenostomy after subtotal gastrectomy due to early gastric cancer were analyzed retrospectively. One hundred and eighty-two patients had Billroth I anastomosis using a 25 mm diameter circular stapler, and 196 patients had anastomosis with a 28 or 29 mm diameter circular stapler. Clinicopathological features and postoperative outcomes were evaluated and compared between the two groups. Delayed gastric emptying was diagnosed by symptoms and simple abdomen X-ray with or without upper gastrointestinal series or endoscopy. Results Postoperative delayed gastric emptying was found in 12 (3.2%) of the 378 patients. Among all the variables, distal margin and circular stapler diameter were significantly different between the cases with delayed gastric emptying and no delayed gastric emptying. There were statistically significant differences in sex, body mass index, comorbidity, complication, and operation type according to circular stapler diameter. In both univariate and multivariate logistic regression analyses, only the stapler diameter was found to be a significant factor affecting delayed gastric emptying (P = 0.040). Conclusion In this study, the circular stapler diameter was one of the most significant predictable factors of delayed gastric emptying for Billroth I gastroduodenostomy. The use of a 28 or 29 mm diameter circular stapler rather than a 25 mm diameter stapler in stapled gastroduodenostomy for early gastric cancer can reduce postoperative delayed gastric emptying associated with anastomosic stenosis or edema with relative safety.

Evidence supports that gastric cancer has an environmental etiology, of which diet appears to be the most important component. The authors examined the effect of diet on the risk of gastric cancer. A case-control study of dietary factors and gastric cancer was conducted between September 1986 and March 1989 in the Barcelona metropolitan area, Spain. One hundred seventeen cases with histologically confirmed diagnosis of gastric adenocarcinoma were matched by age, gender, and whether they possessed a telephone to 234 community controls. One hundred eighty-eight (80.3%) controls were selected by random-digit telephone dialing and 46 (19.7%) by neighborhood of residence. Information about frequency and amount of consumption of 89 food items in one year was gathered by using a questionnaire, and cases and controls were interviewed in their homes by trained interviewers. Unconditional logistic regression was used for the analysis. Gastric cancer risk rose with increasing intake of smoked and pickled foods (OR 3.67 for upper tertile) and salt (OR 2.11 for upper quartile). Intake of citrus fruits (OR 0.47 for upper tertile) and raw-green vegetables (OR 0.56 for upper quartile) appeared to be protective. Gastric cancer risk was not associated with intake of cereals, rice, total vegetables, and fruits as a whole. These data suggest that high intake of salt and smoked and pickled food may be associated with a high risk of gastric cancer, and this association could be due to intragastric formation of nitrosamines. The negative association with citric and green vegetables consumption to be associated with the inhibition of nitrosation process.

Intestinal metaplasia is a precursor lesion of gastric cancer. Infection by Helicobacter pylori is the principal cause of metaplasia. While evidence of the regression of metaplasia after treatment to eradicate this infection has been demonstrated, controversy remains with regard to this subject. The objective of this study was to determine the frequency of the regression of gastric intestinal metaplasia one year after the eradication of Helicobacter pylori. A prospective longitudinal designed study was carried out. The population studied in this research consisted of patients attending the Endoscopy Unit to undergo an upper endoscopy, in whom various symptoms indicated intestinal metaplasia associated with Helicobacter pylori, and who received standard empiric triple therapy to eradicate the bacteria. An upper endoscopy was performed in which four gastric biopsy samples were taken (two from the antrum and two from the body) before and after the eradicating treatment, with the endoscopic and histological findings studied after one year of monitoring. The statistical analysis was conducted using the Fisher's exact test and the McNemar's test. Forty-six patients were studied, of whom 20 (43.5%) were men and 26 (56.5%) were women, with an average age of 58.9 (DE 11.2). Intestinal metaplasia was found in 46 (100%) patients before treatment and in 21 (45.7%) patients post-eradication. Complete intestinal metaplasia (type I) was found in 35 patients (76.1%) before treatment and in 11 (23.9%) patients post-eradication (p = 0.000), while incomplete intestinal metaplasia (type II) was found in 10 (21.7%) patients before treatment and in 10 (21.7%) patients post-eradication. Non-atrophic chronic gastritis was found in 35 (76.1%) patients before treatment and in 32 (69.6%) patients post-eradication. In this study, gastric intestinal metaplasia associated with Helicobacter pylori infection showed a regression of 54.3% one year after the eradication of this microorganism. This treatment could modify the natural history of the development of gastric cancer.

Chronic inflammation of the gastric epithelium has been associated with the pathogenesis of gastric cancer, as it was postulated by Corea's model of gastric carcinogenesis. Helicobacter pylori (Hp) regulates this inflammatory process and promotes gastric carcinogenesis through induction of gene mutations and protein modulation. Recent data raise the cancer stem cell hypothesis, which implies a central role of multipotent cancer cells in oncogenesis of various solid tumors. This review provides a synopsis of gastric cancer initiation and promotion through Hp and stem cell signaling pathways. The expanding research field of Hp-related cancer stem cell biology may offer novel implications for future treatment of upper gastrointestinal cancer. Copyright © 2011 Elsevier Inc.

The goal of this study was to investigate the difference between the learning curves of different maneuvers in laparoscopic spleen-preserving splenic hilar lymphadenectomy for advanced upper gastric cancer. From January 2010 to April 2014, 53 consecutive patients who underwent laparoscopic spleen-preserving splenic hilar lymphadenectomy via the traditional-step maneuver (group A) and 53 consecutive patients via Huang's three-step maneuver (group B) were retrospectively analyzed. No significant difference in patient characteristics were found between the two groups. The learning curves of groups A and B were divided into phase 1 (1-43 cases and 1-30 cases, respectively) and phase 2 (44-53 cases and 31-53 cases, respectively). Compared with group A, the dissection time, bleeding loss and vascular injury were significantly decreased in group B. No significant differences in short-term outcomes were found between the two maneuvers. The multivariate analysis indicated that the body mass index, short gastric vessels, splenic artery type and maneuver were significantly associated with the dissection time in group B. No significant difference in the survival curve was found between the maneuvers. The learning curve of Huang's three-step maneuver was shorter than that of the traditional-step maneuver, and the former represents an ideal maneuver for laparoscopic spleen-preserving splenic hilar lymphadenectomy.To shorten the learning curve at the beginning of laparoscopic spleen-preserving splenic hilar lymphadenectomy, beginners should beneficially use Huang's three-step maneuver and select patients with advanced upper gastric cancer with a body mass index of less than 25 kg/m 2 and the concentrated type of splenic artery.

To discuss the application of the degree of portal systemic shunting in assessing the upper gastrointestinal bleeding in patients with hepatic schistosomiasis. Thirty-three patients with upper gastrointestinal bleeding caused by hepatic schistosomiasis (a bleeding group) and 29 schistosomiasis cirrhosis patients without bleeding (a non-bleeding group) were enrolled as investigation subjects in Jinshan Hospital. The subjects were scanned by the 128 abdominal slice spiral CT. The portal systemic shunting vessels were reconstructed by using thin slab maximum intensity projection (TSMIP) and multiplanar reconstruction (MPR). The degrees of the shunting vessels of the subjects were evaluated and compared, and the relationship between upper gastrointestinal bleeding and the degree of the shunting was analyzed. In the bleeding group, the occurrence rates of the shunting vessels were found as follows: 86.4% in left gastric varices, 68.2% in short gastric varices, 50.0% in esophageal varices, 50.0% in para-esophageal varices, 37.9% in gastric varices, 69.7% in gastric-renal varices, 51.5% in spleen-renal varices, 25.8% in abdominal wall varices, 15.2% in omentum varices, 63.6% in para-splenic varices, 34.8% in umbilical varices, 40.9% in retroperitoneal-paravertebral varices, and 36.4% in mesenteric varices. In the bleeding group, the occurrence rates and the degree of shunt were significantly higher than those in the non-bleeding group in esophageal varices, esophageal vein, left gastric vein and gastric varices (all P < 0.05). CT portal vein reconstruction can accurately display the location, degree and walking of all kinds of shunting vessels. Esophageal varices, esophageal vein, left gastric vein and gastric varices can accurately predict the risk of upper gastrointestinal bleeding in patients with hepatic schistosomiasis. The patents with higher degree of the shunting vessels have a higher risk of gastrointestinal bleeding.

Patients with familial adenomatous polyposis (FAP), an autosomal dominant cancer predisposition syndrome caused by mutations in the APC gene, develop neoplasms in both the upper and lower gastrointestinal (GI) tract. To clarify the upper GI tract lesions in FAP patients in a tertiary care setting, we reviewed specimens from 321 endoscopies in 66 patients with FAP. Tubular adenomas in the small bowel were the most common neoplasms (present in 89% of patients), although only 1 patient developed invasive carcinoma of the small bowel. Several types of gastric neoplasms were identified--65% of patients had at least 1 fundic gland polyp, and 23% of patients had at least 1 gastric foveolar-type gastric adenoma. Pyloric gland adenomas were also enriched, occurring in 6% of patients--this is a novel finding in FAP patients. Despite the high frequency of gastric neoplasms, only 1 patient developed carcinoma in the stomach. The very low frequency of carcinoma in these patients suggests that current screening procedures prevent the vast majority of upper GI tract carcinomas in patients with FAP, at least in the tertiary care setting.

The objective of this study is to evaluate the gastric emptying in patients with systemic lupus erythematosus (SLE) with gastrointestinal involvement using three-dimensional (3D) ultrasonography. The gastric emptying times at 25% (T1), 50% (T2), and 75% (T3) of SLE patients with gastrointestinal involvement (n = 40) and healthy controls (n = 80) were evaluated and compared. In addition, the correlations among the gastric wall thickness, SLE disease activity index (SLEDAI), and upper gastrointestinal symptoms were calculated. The gastric wall thickness was correlated with the SLEDAI (r = 0.928, p < 0.001) and the upper gastrointestinal symptom index (r = 0.848, p < 0.001). The emptying times T1, T2, and T3 of the SLE patients were 17.08 ± 2.65 min (mean ± standard deviation), 39.85 ± 6.54 min, and 83.58 ± 7.12 min, respectively. For healthy controls, they were 19.65 ± 5.39 min, 41.08 ± 7.51 min, and 70.34 ± 8.03 min. The T1 of the SLE patients was shorter (p < 0.01), while the T3 was longer (p < 0.001). Moreover, T3 in the SLE group had the best correlation with the upper gastrointestinal symptom index (r = 0.553, p < 0.001). T1 in the SLE group was anti-correlated with early satiety (r = -0.366, p < 0.05). Combining the emptying times T1 and T3, as well as the gastric wall thickness, the SLEDAI and the upper gastrointestinal symptoms index can provide accurate clinical diagnosis of SLE with gastric involvement.

Stricture at the gastrojejunal anastomosis after Roux-en-Y gastric bypass is a significant sequela that often requires intervention. The diagnosis of stricture is usually established by a recognized constellation of symptoms, followed by contrast radiography or endoscopy. The purpose of this report was to evaluate the accuracy of contrast swallow studies in excluding the diagnosis of gastrojejunal stricture. A retrospective analysis of the charts of 119 patients who had undergone laparoscopic Roux-en-Y gastric bypass, representing 41 upper gastrointestinal (GI) swallow studies, was conducted. Of those patients who underwent GI swallow studies, 30 then underwent definitive upper endoscopy to confirm or rule out stricture. The overall sensitivity, specificity, and negative predictive value of the swallow studies were calculated. Of the 30 patients who underwent upper endoscopic examination for symptoms of stricture after laparoscopic gastric bypass, 20 were confirmed to have a stricture. The sensitivity, specificity, and negative predictive value of the upper GI swallow study in this group was 55%, 100%, and 53%, respectively. The demographics of the patients with strictures were similar to those of the study group as a whole. The results of our study have shown that a positive upper GI swallow study is 100% specific for the presence of stricture. However, the sensitivity and negative predictive value of upper GI swallow studies were poor, making this modality unsatisfactory in definitively excluding the diagnosis of gastrojejunal stricture.

To evaluate the clinical utility of the routine use of postoperative barium swallow to diagnose postoperative complications in patients undergoing open or laparoscopic Roux-en-Y gastric bypass. A total of 417 consecutive patients undergoing Roux-en-Y gastric bypass at our institution between January 1, 2001, and December 31, 2002, were included. We performed 341 open procedures and 76 laparoscopic gastric bypasses. All patients received a limited postoperative fluoroscopic upper gastrointestinal series, except for the patients who exceeded the weight limitation of the radiologic equipment. Radiologic findings of anastomotic complications were anastomotic leak, delayed gastric emptying, gastric outlet obstruction, and gastrogastric fistula. We evaluated clinical signs and symptoms to obtain a list of criteria suggesting these complications. Patients were stratified into 2 groups: those with and those without radiographic anastomotic complications. Clinical and radiologic criteria were compared using univariate and multivariate logistic regression analysis. We noted 42 radiologic abnormalities during a routine postoperative barium swallow evaluation. Among our 417 patients, we documented 12 leaks (2.9%), 19 cases of delayed gastric emptying (4.6%), 4 gastric outlet obstructions (1.0%), and 7 gastrogastric fistulas (1.7%). The combination of fever, tachycardia, and tachypnea was the most specific indicator of a leak, at 0.99 (95% confidence limit, 0.99, 1.01). Nausea with vomiting was the most predictive indicator of delayed gastric emptying and gastric outlet obstruction, with a specificity of 0.99 (95% confidence limit, 0.98, 0.99) and 0.97 (95% confidence limit, 0.96, 0.99), respectively. Postoperative complications after Roux-en-Y gastric bypass surgery are predictable based on the patient's symptoms. The use of routine postoperative fluoroscopic upper gastrointestinal series is unnecessary in asymptomatic patients.

Osteoblast activating peptide (OBAP) was previously reported to be expressed in the rat stomach and to have a vital role in osteogenesis, but its distribution in rat stomach has not been determined. Thus, the aim of the present study was to identify the cell types expressing OBAP in the rat stomach. The stomachs of twelve 10-to-11-week-old male Jc1:SD rats were used. Samples were collected for immunohistochemistry, immunoelectron microscopy and dot blot assay. Immunohistochemical investigation revealed that OBAP was distributed mainly in parietal cells without any expression in chief cells, X/A-like cells or enterochromaffin-like cells. Moreover, OBAP-immunopositive cells were observed mainly in the upper and lower parts of the gastric gland. Significantly high optical density of immunopositive cells was observed in the upper and lower gastric gland regions. The dot blot assay confirmed that OBAP is secreted by parietal cells and that it is present in the gastric gland lumen. Immunoelectron microscopy demonstrated that OBAP was confined to the mitochondrial inner membrane within parietal cells and that the number of mitochondria in the upper and lower parts of the gastric epithelium was significantly larger than the number in the middle part of the gastric epithelium. Based on the results, it was concluded that OBAP is mainly produced by mitochondria of parietal cells in the upper and lower parts of the gastric epithelium. Moreover, the presence of OBAP in the gastric gland lumen suggests an exocrine mechanism of release. Copyright © 2015 Elsevier GmbH. All rights reserved.

The authors describe a case of a 61-year-old female patient, which presented on multidetector computed tomographic (MDCT) angiography a gastrosplenic trunk (GST) and common hepatic artery (CHA) arose independently from abdominal aorta (AA). The GST arose from the anterior wall of the AA, at the level of upper edge of the L1 vertebral body. The left gastric artery (LGA) arose from the superior wall of the GST. The splenic artery (SA) continuous the path of GST. The CHA arose from the anterior wall of the AA, at the level of upper one third of the L1 vertebral body, at 15.3 mm above the origin of superior mesenteric artery (SMA). The incidence and developmental and clinical significance of this vascular variation is discussed with a detailed review of the literature.

Double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) is the standard gastric cancer screening method in Japan. Atrophic gastritis and enlarged gastric folds are considered the two major features of Helicobacter pylori-induced chronic gastritis, but the clinical meaning of evaluating them by UGI-XR has not been elucidated. We analyzed healthy UGI-XR examinees without a history of gastrectomy, previous Helicobacter pylori eradication and usage of gastric acid suppressants. Of the 6433 subjects, 1936 (30.1 %) had atrophic gastritis and 1253 (19.5 %) had enlarged gastric folds. During the 3-year prospective observational follow-up, gastric cancer developed in seven subjects, six of whom (85.7 %) had atrophic gastritis with H. pylori infection and five of whom (71.4 %) had enlarged gastric folds with H. pylori infection. The Kaplan-Meier method with log-rank testing revealed that both UGI-XR-based atrophic gastritis (p = 0.0011) and enlarged gastric folds (p = 0.0003) are significant predictors for future gastric cancer incidence.

Acute upper gastrointestinal bleeding is a rare, but serious complication of gastric bypass surgery. The inaccessibility of the excluded stomach restrains postoperative examination and treatment of the gastric remnant and duodenum, and represents a major challenge, especially in the emergency setting. A 59-year-old patient with previous history of peptic ulcer disease had an upper gastrointestinal bleeding from a duodenal ulcer two years after having a gastric bypass procedure for morbid obesity. After negative upper endoscopy finding, he was urgently evaluated for gastrointestinal bleeding. At emergency laparotomy, the bleeding duodenal ulcer was identified by intraoperative endoscopy through gastrotomy. The patient recovered well after surgical hemostasis, excision of the duodenal ulcer and completion of the remnant gastrectomy. Every general practitioner, gastroenterologist and general surgeon should be aware of growing incidence of bariatric operations and coherently possible complications after such procedures, which modify patient's anatomy and physiology.

A 66-year-old woman was admitted to our clinic for appetite loss and abdominal distension in August 1995. Endoscopic study revealed an advanced gastric cancer in the upper body of her stomach. Abdominal CT study revealed massive ascites and para-aortic lymph nodal involvement. Cytological study of the ascites revealed class V. She was diagnosed to be in the terminal stage of gastric cancer with carcinomatosa peritonitis. Combination chemotherapy with 5-fluorouracil (5-FU) and low-dose cisplatin (CDDP) was given by continuous intravenous injection of 5-FU 500 mg/day, and intermittent intravenous injection of CDDP 30 mg/week was performed for reduction of the ascites and her complaint. Endoscopic study 6 weeks after starting chemotherapy could not find crater of the gastric cancer but only a shallow ulcerative lesion. The biopsy specimen of that lesion was group III. No ascites and over 50% reduction of the para-aortic lymph node were found by the abdominal CT study. This state persisted over 4 weeks. No myelo-suppression, renal dysfunction or any severe side effect were observed during chemotherapy. Her performance status improved from 3 to 1.

Very few data are available about Zn in gastrointestinal fluids in humans. To obtain data in one such fluid Zn was measured in plasma and gastric fluid, obtained by direct visual aspiration through an endoscope placed into the gastric fundus, in 36 subjects with normal gastrointestinal mucosa (N) and in 36 patients with the following upper gastrointestinal pathology confirmed by endoscopy: 13 with esophagitis (E), 9 with gastritis (G) and 14 with duodenal ulcer disease (DU). Plasma and gastric fluid Zn were estimated by flame atomic absorption spectrophotometry. Mean plasma Zn was significantly lower than normal in patients with Emore » (N, 87 +/- 2 ..mu..g/dl, M +/- SEM; E, 75 +/- 4, p < 0.01) but plasma values were similar to normal in the other patient groups (G, 89 +/- 4; DU, 87 +/- 2). Mean gastric fluid zinc in G was significantly higher than in normal subjects (G, 664 +/- 159 ..mu..g/L; N, 360 +/- 43, p < 0.02) but not significantly different from normal in patients with DU or E (DU, 402 +/- 76; E, 307 +/- 55). Mean gastric fluid Zn in women with DU was approximately 45% higher than in men with DU, although it was 17% lower in normal women than in normal men. Compared to other normal tissues gastric fluid Zn is about 1/3 that in serum and about 3 times that in saliva. These results indicate that Zn in plasma and gastric fluid is altered in some upper gastrointestinal diseases.« less

Differences in the molecular biology of adenocarcinoma of the esophagus, gastric cardia, and upper gastric third.

PubMed

Lehmann, Kuno; Schneider, Paul M

2010-01-01

Adenocarcinoma of the distal esophagus, gastric cardia, and upper gastric third are grouped in type I-III by the Siewert classification. This classification is based on the endoscopic localisation of the tumor center, and is the most important diagnostic tool to group these tumors. On a molecular level, there is currently no marker that would allow to differentiate the three different types. Furthermore, the Siewert classification was not uniformly used in the recent literature, making interpretation and generalization of these results difficult. However, several potential targets have been identified that may help to separate these tumors by molecular markers, and are summarized in this chapter.

Confocal endomicroscopy for in vivo microscopic analysis of upper gastrointestinal tract premalignant and malignant lesions.

2008-03-01

Confocal LASER endomicroscopy (CLE) is a new endoscopic technique which allows subsurface in vivo microscopic analysis during ongoing endoscopy, using systemically or topically administered fluorescent agents. It allows targeted biopsies to be taken, potentially improving the diagnostic rate in certain gastrointestinal diseases. Worldwide experience with CLE for upper gastrointestinal malignant and premalignant lesions is still reduced. Potential clinical applications are presented, including diagnosis of NERD, Barrett's esophagus, atrophic gatritis, gastric intestinal metaplasia and dysplasia, gastric adenomatous or hyperplastic polyps, gastric cancer.

Although recent studies have suggested that tooth loss is positively related to the risk of gastric non-cardia cancer, the underlying oral health conditions potentially responsible for the association remain unknown. We investigated whether clinical and behavioral measures of oral health are associated with the risk of gastric precancerous lesions. We conducted a cross-sectional study of 131 patients undergoing upper gastrointestinal endoscopy. Cases were defined as those with gastric precancerous lesions including intestinal metaplasia or chronic atrophic gastritis on the basis of standard biopsy review. A validated structured questionnaire was administered to obtain information on oral health behaviors. A comprehensive clinical oral health examination was performed on a subset of 91 patients to evaluate for periodontal disease and dental caries experience. A total of 41 (31%) cases of gastric precancerous lesions were identified. Compared with non-cases, cases were significantly more likely to not floss their teeth [odds ratio (OR) = 2.89, 95% confidence interval (CI): 1.09-7.64], adjusting for age, sex, race, body mass index, smoking status, educational attainment and Helicobacter pylori status in serum. Among participants who completed the oral examination, cases (n = 28) were more likely to have a higher percentage of sites with gingival bleeding than non-cases [OR = 2.63, 95% CI: 1.37-5.05 for a standard deviation increase in bleeding sites (equivalent to 19.7%)], independent of potential confounders. Our findings demonstrate that specific oral health conditions and behaviors such as gingival bleeding and tooth flossing are associated with gastric precancerous lesions.

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.

Heterotopic gastric mucosa patches are congenital gastrointestinal abnormalities and have been reported to occur anywhere along the gastrointestinal tract from mouth to anus. Complications of heterotopic gastric mucosa include dysphagia, upper gastrointestinal bleeding, upper esophageal ring stricture, adenocarcinoma and fistula formation. In this case report we describe the diagnosis and treatment of the first case of esophago-bronchial fistula due to heterotopic gastric mucosa in mid esophagus. A 40-year old former professional soccer player was referred to our department for treatment of an esophago-bronchial fistula. Microscopic examination of the biopsies taken from the esophageal fistula revealed the presence of gastric heterotopic mucosa. We decided to do a non-surgical therapeutic endoscopic procedure. A sclerotherapy catheter was inserted through which 1 mL of ready to use synthetic surgical glue was applied in the fistula and it closed the fistula opening with excellent results.

Clinical and laboratory study of postvagotomy diarrhoea

Thirty-two patients with diarrhoea, on average four years following truncal vagotomy and drainage, were studied. A comparison was made with 24 patients without postvagotomy diarrhoea. The incidence of bacterial colonization of the upper small intestine was no different in the two groups, though patients with a gastroenterostomy had a significantly higher incidence than those with a pyloroplasty. There was a higher incidence of `anaerobic colonization' in patients with diarrhoea, but statistical significance was not reached. Colonization was associated with significantly lower levels of gastric acid secretion. Though 13 patients with diarrhoea had an abnormal faecal fat excretion, no correlation could be found between this and the severity of the diarrhoea or bacterial colonization, either with an anaerobic or a coliform type flora. In patients with diarrhoea, no small intestinal mucosal abnormality was detected, the mean haematological and serum biochemistry values were within normal limits, and the body weight was similar to that before operation. Two patients with diarrhoea had abnormal haematological values five years following vagotomy and gastroenterostomy in association with `anaerobic colonization' of the upper small intestine. As the incidence of haematological abnormalities after gastric surgery increases with time, colonized patients might merit particularly close clinical observation. PMID:4608280

Effects of preoperative one week enteral nutrition (EN) support on the postoperative nutritional status, immune function and inflammatory response of gastric cancer patients were investigated. 106 cases of gastric cancer patients were randomly divided into preoperative one week EN group (trial group) and early postoperative EN group (control group), which were continuously treated with EN support until the postoperative 9th day according to different treatment protocols. All the patients were checked for their body weight, skinfold thickness, upper arm circumference, white blood cell count (WBC), albumin (ALB), prealbumin (PA), C-reactive protein (CRP), humoral immunity (IgA, IgG), T cell subsets (CD4, CD8 and CD4/CD8), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), etc. on the preoperative and the postoperative 1st and 10th day, respectively. PA and IgG levels of the experimental group were higher than those of the control group on the postoperative 10th day, whereas IL-6 level of the experimental group was lower than that of the control group. EN support for preoperative gastric cancer patients will improve the postoperative nutritional status and immune function, alleviate inflammatory response, and facilitate the recovery of patients.

Omega loop gastric bypass is a successful bariatric surgery with numerous favorable circumstances as being basic, effective on weight reduction and treatment of obesity associated metabolic disorder, the short expectation to learn and adapt, and the simplicity of correction and inversion. However, there are arguments about the possibility of biliary reflux and/or the potential danger of gastroesophageal malignancy after the procedure. Fifty patients experiencing morbid obesity with body mass index >40 or >35 kg/m 2 with two related comorbidities, for example, diabetes type II, hypertension, or dyslipidemia, underwent omega loop gastric bypass with a follow-up period up to 18 months, investigating for any symptom of reflux infection by upper gastrointestinal tract endoscopy and pH metry. Reflux esophagitis (a gastroesophageal reflux disease) was detected in 3 patients (6%); 2 cases (4%) showed (Grade A) acidic reflux esophagitis at 6 and 12 months postoperatively. Just 1 case (2%) had experienced gastroesophageal biliary reflux esophagitis (Grade A) at 12 months. No metaplasia or dysplasia was detected in the endoscopic biopsies. Omega loop gastric bypass is a safe and effective bariatric procedure with low incidence of postoperative biliary reflux, metaplasia, or dysplasia at the esophagogastric junction, confirmed 18 months after the operation.

To report 6-month safety and efficacy results of a pilot study of left gastric artery (LGA) embolization for the treatment of morbid obesity (ie, body mass index [BMI] > 40 kg/m(2)). Four white patients (three women; average age, 41 y [range, 30-54 y]; mean weight, 259.3 lbs [range, 199-296 lbs]; mean BMI, 42.4 kg/m(2) [range, 40.2-44.9 kg/m(2)]) underwent an LGA embolization procedure with 300-500-µm Bead Block particles via right common femoral or left radial artery approach. Follow-up included upper endoscopy at 3 days and 30 days if necessary and a gastric emptying study at 3 months. Tracked parameters included adverse events; weight change; ghrelin, leptin, and cholecystokinin levels; and quality of life (QOL; by Short Form 36 version 2 questionnaire). Three minor complications (superficial gastric ulcerations healed by 30 d) occurred that did not require hospitalization. There were no serious adverse events. Average body weight change at 6 months was -20.3 lbs (n = 4; range, -6 to -38 lbs), or -8.5% (range, -2.2% to -19.1%). Average excess body weight loss at 6 months was -17.2% (range, -4.2% to -38.5%). Patient 4, who had diabetes, showed an improvement in hemoglobin A1c level (7.4% to 6.3%) at 6 months. QOL measures showed a general trend toward improvement, with the average physical component score improving by 9.5 points (range, 3.2-17.2) and mental component score improving by 9.6 points (range, 0.2-19.3) at 6 months. Preliminary data support LGA embolization as a potentially safe procedure that warrants further investigation for weight loss in morbidly obese patients. Copyright © 2016 SIR.

Objective: To investigate the effect of fried food intake on the pathogenesis of gastric cancer and precancerous lesions. Methods: From 2005 to 2013, the residents aged 40-69 years from 11 counties/cities where cancer screening of upper gastrointestinal cancer were conducted in rural areas of Henan province as the subjects (82 367 cases). The information such as demography and lifestyle was collected. The residents were screened with endoscopic examination. The biopsy sampleswere diagnosed pathologically, according to pathological diagnosis criteria, the subjects with high risk were divided into the groups with different pathological degrees. The multivariate ordinal logistic regression analysis was used to analyze the relationship between the frequency of fried food intake and gastric cancer and precancerous lesions. Results: The study coverd 46 425 males and 35 942 females, with a age of (53.46±8.07)years. The study collected 6 707 cases of normal stomach, 2 325 cases of low grade intraepithelial neoplasia, 226 cases of high grade intraepithelial neoplasia and 331 cases of gastric cancer. Multivariate logistic regression analysis showed that, compared with those whoeat fried food less than one time per week, fried foods intake (<2 times/week: OR= 1.89, 95 %CI: 1.57-2.28; ≥ 2 times/week: OR= 1.91, 95 %CI: 1.66-2.20) were a risk factor for gastric cancer and precancerous lesions after adjustment for age, sex, marital status, educational level, body mass index (BMI), smoking and drinking status. Conclusion: The intake of fried food is a risk factor for gastric cancer and precancerous lesions. Therefore, reducing the intake of fried food can prevent the occurrence of gastric carcinoma and precancerous lesions.

Little is known about the development of excess skin and requests for body-contouring surgery after bariatric surgery in adolescents. Forty-seven of 86 adolescents that had undergone gastric bypass surgery answered two questionnaires regarding excess skin and requests for and performed body-contouring surgery. An objective assessment of the amount of excess skin was also performed. The results were compared to earlier results from postbariatric adults. The most common overall problem in adolescents was the feeling of having an unattractive body (91 percent). The most common locations for developing excess skin were the upper arms and thighs according to the measurements. Five of 47 adolescents had undergone body-contouring surgery, and 88 percent of the others desired one or more body-contouring operations. Correlations were found between the objectively measured excess skin and the subjectively experienced amount of excess skin. Correlations were also found between the measured excess skin and the experienced discomfort of excess skin for the abdomen, breast/chest, upper arms, and chin. The authors' results indicate that bariatric surgery in adolescents often leads to severe problems associated with excess skin in both sexes. Thus, the commonly held belief that young people do not develop excess skin to the same extent as adults is strongly questioned. Health care professionals must address the current imbalance between requests for and the performance of body-contouring surgery in adolescents. Therapeutic, IV.

Cerebral gas embolism as a result of upper gastrointestinal endoscopy is a rare complication and bares a high morbidity. A patient is presented who underwent an upper endoscopy for evaluation of a gastric-mediastinal fistula after subtotal oesophagectomy and gastric tube reconstruction because of oesophageal cancer. During the procedure, cerebral gas emboli developed resulting in an acute left-sided hemiparesis. After hyperbaric oxygen therapy, the patient recovered almost completely. The aetiology and treatment is discussed based on the reviewed literature. Once cerebral gas emboli are recognized, patient outcome can be improved by hyperbaric oxygen therapy.

We report a case of esophageal perforation caused by an explosion, but which was not diagnosed until 3 days after the injury. A 53-year-old worker sustained superficial dermal burns to his trachea, face, neck, and legs during an explosion. The burns were treated conservatively at a local hospital, but he was transferred to our hospital 3 days after the injury, when mediastinal emphysema and bilateral pleural effusion became evident. An esophagogram followed by computed tomography showed an esophageal perforation caused by the blast injury, and we performed an esophagectomy with recontruction of the gastric tube. After the operation, an X-ray showed a foreign body in the lower abdomen, which we found in the upper thoracic esophagus on the day of injury. We surmised that the patient had inadvertently swallowed a foreign body, which had been heated and scattered by the explosion, and it had melted the upper thoracic esophagus.

The effect of physiological doses of guar gum (Guarem), 5 g, and fiber-enriched wheat bran (Fiberform), 10.5 g, on gastric emptying was studied by two different methods in healthy subjects: by a simple isotope localization monitor placed over the upper part of the abdomen and by gamma camera. The fiber preparations were added to a semisolid meal consisting of wheatmeal porridge and juice, using technetium-99 DTPA as a marker. The gamma camera showed no effect of fiber on gastric emptying. The isotope localization monitor, however, indicated that Fiberform prevented a postprandial accumulation of the meal within the upper part of the stomach. The simple isotope localization monitor cannot be recommended for measurements of gastric emptying.

A 74-year-old man had an endoscopic type 0'-IIc tumor in the upper gastric body on the greater curvature and biopsy showed the tumor to be a well-differentiated adenocarcinoma (Group 5). He was referred to us for endoscopic submucosal dissection (ESD). Endoscopy revealed fold convergency, fold swelling, and fusion of the fold, indicating tumor invasion into the submucosa, which was outside the indications for ESD. In addition, there was an increase of serum bone-type alkaline phosphatase (ALP-III and ALP-IV) and urinary cross-linked N-terminal telopeptide of type I collagen (a bone metabolism marker), while (18)F-fluorodeoxyglucose positron emission tomography showed increased uptake in the left pelvis and Th10, suggesting bone metastases. We first diagnosed gastric cancer with bone metastases; however, the symptoms suggested pathological bone fracture and no bone pain. Therefore, a computed tomography-guided aspiration bone biopsy was performed to exclude the possibility of Paget's disease of bone. Biopsy specimens revealed no tumor and a mosaic pattern. No increased uptake of (18)F-FAMT (L-[3-(18)F] α-methyltyrosine) supported a diagnosis of no bone metastases from gastric cancer. We finally diagnosed gastric cancer accompanied by Paget's disease of bone and performed a laparoscopy-assisted proximal gastrectomy. The pathological diagnosis was U less 0-IIb, and U post 0-IIc ypT1a (M) N0H0P0M0 yp stage IA. In gastric cancer patients with suspected bone metastasis, we also need to consider Paget's disease of bone.

In adults, most intussusceptions develop from a lesion, usually a benign or malignant neoplasm, and can occur at any site in the gastrointestinal tract. Intussusception in the proximal gastrointestinal tract is uncommon, and gastro-gastric intussusception is extremely rare. We present a case of gastro-gastric intussusception secondary to a primary gastric lymphoma. An 82-year-old female patient presented with acute onset chest pain and vomiting. Abdominal CT revealed a gastro-gastric intussusception. We performed upper gastrointestinal endoscopy, revealing a large gastric mass invaginated into the gastric lumen and distorting the distal stomach. Uncomplicated gastric reposition was achieved with endoscopy of the distal stomach. Histological evaluation of the gastric mass revealed a diffuse large B cell lymphoma that was treated with chemotherapy.

Objective The upper gastrointestinal characteristics in Japanese familial adenomatous polyposis patients have not yet been clarified. The aim of the present study was to elucidate these characteristics in Japanese familial adenomatous polyposis patients. Methods This study was conducted by the study group for familial adenomatous polyposis in the Japanese Society for Cancer of the Colon and Rectum. Familial adenomatous polyposis patients who underwent surgical resection from 2000 to 2012 were included in the study. Results In total, 303 familial adenomatous polyposis patients were enrolled, with 265 cases of classical familial adenomatous polyposis (≥100 adenomas) and 38 cases of attenuated familial adenomatous polyposis (<100 adenomas). Fundic gland polyps were significantly more common in classical familial adenomatous polyposis than in attenuated familial adenomatous polyposis; however, gastric cancer was significantly less common in classical familial adenomatous polyposis than in attenuated familial adenomatous polyposis. Gastric cancer and duodenal adenoma were significantly more common in familial adenomatous polyposis patients with gastric adenoma than in those without gastric adenoma. Duodenal cancer was detected in 7 of 72 familial adenomatous polyposis patients with duodenal adenoma. The median tumour risk in 50-year-old familial adenomatous polyposis patients was 55.3, 21.8, 3.8, 39.2 and 7.7% for fundic gland polyp, gastric adenoma, gastric cancer, duodenal adenoma and duodenal cancer, respectively. Conclusions Upper gastrointestinal tumours/polyps were frequently found in familial adenomatous polyposis patients, and their incidences were correlated; however, the frequency of gastric cancer in Japanese familial adenomatous polyposis patients was similar to that in the general population.

This study assessed the orocecal transit time (OCTT) in a group of patients with type 1 diabetes mellitus and its relationships with gastrointestinal symptoms, glycemic control, chronic complications of diabetes, anthropometric indices, gastric emptying, small intestinal bacterial overgrowth (SIBO), and psychological distress. Twenty-eight patients with long-standing (>10 years) type 1 diabetes mellitus (22 women, six men; mean age, 39 ± 9 years) participated in the study. The lactulose hydrogen breath test was used to determine OCTT and the occurrence of SIBO. The presence of anxiety and depression was assessed by the Hospital Anxiety and Depression scale. Gastric emptying was measured by scintigraphy. Anthropometric indices included body mass index, percentage body fat, midarm circumference, and arm muscle area. There was a statistically significant increase in OCTT values in diabetes patients (79 ± 41 min) in comparison with controls (54 ± 17 min) (P=0.01). Individual analysis showed that OCTT was above the upper limit (mean+2 SD) in 30.8% of patients. All anthropometric parameters were significantly decreased (P<0.05) in patients with prolonged OCTT in comparison with those with normal OCTT. In contrast, there was no statistically significant association between prolonged OCTT and gastrointestinal symptoms, peripheral neuropathy, diabetic retinopathy, glycated hemoglobin, delayed gastric emptying, SIBO, anxiety, or depression. Small bowel transit may be delayed in about one-third of patients with long-standing type 1 diabetes mellitus. This abnormality seems to have a negative effect on nutritional status in these patients.

Total or proximal gastrectomy is usually performed for early proximal gastric carcinoma, but the optimal type of gastrectomy is still unknown. We evaluated short-term outcomes and nutritional status after laparoscopic subtotal gastrectomy (LsTG) in comparison with laparoscopic total gastrectomy (LTG) and laparoscopic proximal gastrectomy (LPG). We analyzed 113 patients who underwent LsTG (n = 38), LTG (n = 48), or LPG (n = 27) for cStage I gastric cancer located in the upper third of the stomach. Postoperative morbidities, nutritional status including body weight, serum albumin, hemoglobin, the prognostic nutritional index (PNI), and endoscopic findings at 1 year after surgery were compared between LsTG and both LTG and LPG. Operation time and intraoperative blood loss were similar among the three groups. The incidence of postoperative morbidities was lower in LsTG than in LTG. The degree of body weight loss was significantly smaller in LsTG than in LTG at 6 and 12 months. At 12 months, LsTG resulted in better serum albumin and PNI than LPG, and better hemoglobin than LTG. Endoscopic examination demonstrated that one LsTG patient and two LPG patients had reflux esophagitis. Remnant gastritis was observed more frequently in LPG than in LsTG. No LsTG patient had bile reflux, although it was observed in four LPG patients. LsTG with a very small remnant stomach had favorable short-term outcomes and nutritional status compared with LTG and LPG, so it may be a better treatment option for cStage I proximal gastric carcinoma.

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.

Intraluminal erosion of a laparoscopic gastric band into the stomach has been reported as a complication of laparoscopic adjustable gastric banding. To our knowledge, however, intraluminal erosion of the band tubing into the duodenum has not been described. We report a 46-year-old man in whom a laparoscopic adjustable gastric band tubing eroded into the duodenal lumen, causing recurrent port-site infections. This complication was diagnosed on upper endoscopy and also, in retrospect, on an upper gastrointestinal barium study and computed tomography. The patient underwent surgical removal of the band and tubing, with a primary duodenal repair, and made a complete recovery without complications. Erosion of laparoscopic band tubing into the duodenum should be included in the differential diagnosis for recurrent port-site infections after laparoscopic adjustable gastric banding. Radiographic or endoscopic visualization of the intraluminal portion of the tubing may be required for confirmation. Definitive treatment of this complication entails surgical removal of the tubing from the duodenum.

Changes in upper gastrointestinal physiology with age.

Newton, J L

Diseases of the upper gastrointestinal tract such as peptic ulceration and gastric cancer become more common and more severe with advancing age. In the normal stomach and duodenum, there is a balance between mucosal protective mechanisms and endogenous (gastric acid and pepsin) and exogenous aggressive factors. The high incidence of gastrointestinal pathology seen in older age groups is not related to increase in the secretion of endogenous aggressive factors. Recent work suggests that gastrointestinal mucosal protective mechanisms are impaired with age. The roles in the gastrointestinal tract of molecules that have been implicated in mucosal repair, such as trefoil peptides and matrix components, are beginning to be elucidated and their study in older people is essential to ensure appropriate, efficient, cost-effective management of gastric pathology in the elderly. Strategies to improve the management of upper gastrointestinal diseases in older people will reduce mortality and improve quality of life.

Background: The incidence and characteristics of gastric cancer have been shown to vary widely across Western and Eastern countries. Our study had two aims: to evaluate long-term trends in gastric adenocarcinoma in Japan over a period of 70 years, and to anticipate the future of gastric cancer in Japan, through comparison with data from the United States. Methods: Japanese patient data for 19,306 incident cases of gastric adenocarcinoma from 1946 - 2014 were collected from the Gastric Cancer Database at the Cancer Institute Hospital, Tokyo, Japan (CIH-GCDB). U.S. patient data for 78,625 incident cases of gastric cancer from 1973 - 2012 were obtained from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database. Changes over time in patient and tumor characteristics were investigated in these two cohorts. Results: There was a marked reduction of cancer incidence in the lower third of the stomach in the CIH-GCDB; over 70% to around 30%. The incidence in the upper third has been increasing steadily over time; 3% to 19%, although the number of cardia tumors has not changed. An increase in elderly and obese patients was also noted. In the U.S. population, there was a significant difference in the primary site across races. A notable overall increase in cardia cancer was evident in the Western population during the study period, with no similar change evident in the Japanese population over the last 15 years. In the East Asian population, the proportional frequency of tumors in the cardia was lower and that of tumors in the pyloric antrum was higher. Conclusion: In Japan, cancer in the antrum or pylorus of the stomach has been declining, whereas cancer in the body has been increasing. Unlike the Western population in the United States, adenocarcinoma of esophago-gastric junction is not increasing in Japan. PMID:28819392

Heterotopic gastric mucosa in the gallbladder is an unusual entity and is usually clinically silent. We report a 75-year-old female patient who presented with intermittent upper abdomial pain radiating to the back. Abdominal imaging studies showed a sessile polypoid lesion and a gallstone in the gallbladder. Gallbladder carcinoma was suspected and cholecystectomy performed. Intraoperative frozen section examination suggested mucinous tumor, suspicious for malignancy. However, the permanent sections revealed aberrant gastric tissue consisted of gastric pyloric and fundic glands of heterotopic gastric mucosa with intestinal metaplasia in the gallbladder.

An increasing amount of attention has been paid to minimally invasive function-preserving gastrectomy, with an increase in incidence of early gastric cancer in the upper stomach. This study aimed to compare oncological outcomes, surgical stress, and nutritional status between robot-assisted proximal gastrectomy (RAPG) and laparoscopy-assisted proximal gastrectomy (LAPG). Eighty-nine patients were enrolled in this retrospective study between November 2011 and December 2013. Among them, 27 patients underwent RAPG and 62 underwent LAPG. Perioperative parameters, surgical stress, nutritional status, disease-free survival, and overall survival were compared between the 2 groups. Sex, age, and comorbidity were similar in the RAPG and LAPG groups. There were also similar perioperative outcomes regarding operation time, complications, and length of hospital stay between the groups. The reflux esophagitis rates following RAPG and LAPG were 18.5% and 14.5%, respectively ( P = .842). However, patients in the RAPG group had less blood loss ( P = .024), more harvested lymph nodes ( P = .021), and higher costs than those in the LAPG group ( P < .001). With regard to surgical stress, no significant differences were observed in C-reactive protein concentrations and white blood cell count on postoperative days 1, 3, and 7 between the groups ( Ps > .05). There appeared to be higher hemoglobin levels at 6 months ( P = .053) and a higher body mass index at 12 months ( P = .056) postoperatively in patients in the RAPG group compared with those in the LAPG group, but this difference was not significant. Similar disease-free survival and overall survival rates were observed between the groups. RAPG could be an alternative to LAPG for patients with early gastric cancer in the upper stomach with comparable oncological safety and nutritional status. Further well-designed, prospective, large-scale studies are needed to validate these results.

AIM: To investigate the outcome and effectiveness of two screening programs, National Cancer Screening Program (NCSP) and opportunistic screening (OS), for the detection of gastric cancer. METHODS: A total of 45  654 subjects underwent upper endoscopy as part of the NCSP or OS at the Chung-Ang University Healthcare System in Korea between January 2007 and December 2010. The study population was comprised of subjects over the age of 40 years. More specifically, subjects who took part in the NCSP were Medicaid recipients and beneficiaries of the National Health Insurance Corporation. Still photographs from the endoscopies diagnosed as gastric cancer were reviewed by two experienced endoscopists. RESULTS: The mean age of the screened subjects was 55 years for men and 54 years for women. A total of 126 cases (0.28%) of gastric cancer were detected from both screening programs; 100 cases (0.3%) from NCSP and in 26 cases (0.2%) from OS. The proportion of early gastric cancer (EGC) detected in NCSP was higher than that in OS (74.0% vs 53.8%, P = 0.046). Among the 34  416 screenees in NCSP, 6585 (19.1%) underwent upper endoscopy every other year as scheduled. Among the 11  238 screenees in OS, 3050 (27.1%) underwent upper endoscopy at least once every two years during the study period. The detection rate of gastric cancer was found to be significantly higher during irregular follow-up than during regular follow-up in both screening programs (0.3% vs 0.2%, P = 0.036). A higher incidence of EGC than advanced gastric cancer was observed during regular follow-up compared with irregular follow-up. CONCLUSION: Compliance to the screening program is more important than the type of screening system used. PMID:23430471

Balloon-Occluded Retrograde Transvenous Obliteration of Gastric Varices: Concept, Basic Techniques, and Outcomes

PubMed Central

Saad, Wael E. A.

2012-01-01

Patients with gastric variceal bleeding require a multidisciplinary team approach including hepatologists, endoscopists, diagnostic radiologists, and interventional radiologists. Upper gastrointestinal endoscopy is the first-line diagnostic and management tool for bleeding gastric varices, as it is in all upper gastrointestinal bleeding scenarios. In the United States when endoscopy fails to control gastric variceal bleeding, a transjugular intrahepatic portosystemic shunt (TIPS) traditionally is performed along the classic teachings of decompressing the portal circulation. However, TIPS has not shown the same effectiveness in controlling gastric variceal bleeding that it has with esophageal variceal bleeding. For the past 2 decades, the balloon-occluded retrograde transvenous obliteration (BRTO) procedure has become common practice in Asia for the management of gastric varices. BRTO is gaining popularity in the United States. It has been shown to be effective in controlling gastric variceal bleeding with low rebleed rates. BRTO has many advantages over TIPS in that it is less invasive and can be performed on patients with poor hepatic reserve and those with encephalopathy (and may even improve both). However, its by-product is occlusion of a spontaneous hepatofugal (TIPS equivalent) shunt, and thus it is contradictory to the traditional American doctrine of portal decompression. Indeed, BRTO causes an increase in portal hypertension, with potential aggravation of esophageal varices and ascites. This article discusses the concept, technique, and outcomes of BRTO within the broader management of gastric varices. PMID:23729982

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.

Background Roux-en-Y gastric bypass (RYGB) is the most effective method for the treatment of obesity and metabolic disease Roux-en-Y gastric bypass (RYGB) may reduce body weight by altering the feeding responses evoked by the short term satiety peptides. Materials and Methods Here, we measured meal size (MS, chow), intermeal interval (IMI) length and satiety ratio (SR, IMI/MS; food consumed per a unit of time) by the small and the large forms of gastrin releasing peptide (GRP) in rats, GRP-10 and GRP-29 (0, 0.1, 0.5 nmol/kg) infused in the celiac artery (CA, supplies stomach and upper duodenum) and the cranial mesenteric artery (CMA, supplies small and large intestine) in a RYGB rat model. Results GRP-10 reduced MS, prolonged the IMI and increased the SR only in the RYGB group, whereas GRP-29 evoked these responses by both routes and in both groups. Conclusion The RYGB procedure augments the feeding responses evoked by exogenous GRP, possibly by decreasing total food intake, increasing latency to the first meal, decreasing number of meals or altering the sites of action regulating MS and IMI length by the two peptides.

To selectively visualize the left gastric vein (LGV) with hepatopetal flow information by non-contrast-enhanced magnetic resonance angiography under a hypothesis that change in the LGV flow direction can predict the development of esophageal varices; and to optimize the acquisition protocol in healthy subjects. Respiratory-gated three-dimensional balanced steady-state free-precession scans were conducted on 31 healthy subjects using two methods (A and B) for visualizing the LGV with hepatopetal flow. In method A, two time-spatial labeling inversion pulses (Time-SLIP) were placed on the whole abdomen and the area from the gastric fornix to the upper body, excluding the LGV area. In method B, nonselective inversion recovery pulse was used and one Time-SLIP was placed on the esophagogastric junction. The detectability and consistency of LGV were evaluated using the two methods and ultrasonography (US). Left gastric veins by method A, B, and US were detected in 30 (97%), 24 (77%), and 23 (74%) subjects, respectively. LGV flow by US was hepatopetal in 22 subjects and stagnant in one subject. All hepatopetal LGVs by US coincided with the visualized vessels in both methods. One subject with non-visualized LGV in method A showed stagnant LGV by US. Hepatopetal LGV could be selectively visualized by method A in healthy subjects.

Inhibitory neurotransmission regulates vagal efferent activity and gastric motility

PubMed Central

McMenamin, Caitlin A; Travagli, R Alberto

2016-01-01

The gastrointestinal tract receives extrinsic innervation from both the sympathetic and parasympathetic nervous systems, which regulate and modulate the function of the intrinsic (enteric) nervous system. The stomach and upper gastrointestinal tract in particular are heavily influenced by the parasympathetic nervous system, supplied by the vagus nerve, and disruption of vagal sensory or motor functions results in disorganized motility patterns, disrupted receptive relaxation and accommodation, and delayed gastric emptying, amongst others. Studies from several laboratories have shown that the activity of vagal efferent motoneurons innervating the upper GI tract is inhibited tonically by GABAergic synaptic inputs from the adjacent nucleus tractus solitarius. Disruption of this influential central GABA input impacts vagal efferent output, hence gastric functions, significantly. The purpose of this review is to describe the development, physiology, and pathophysiology of this functionally dominant inhibitory synapse and its role in regulating vagally determined gastric functions.

The preoperative diagnosis of T stage is important in selecting limited treatments, such as laparoscopic proximal gastrectomy (LPG), which lacks the ability to palpate the tumor. Therefore, the present study examined the accuracy of preoperative diagnosis of the depth of tumor invasion in early gastric cancer from the view point of the indication for LPG. A total of 193 patients with cT1 gastric cancer underwent LPG with gastrointestinal endoscopic examinations and a series of upper gastrointestinal radiographs. The patients with pT1 were classified into the correctly diagnosed group (163 patients, 84.5%), and those with pT2 or deeper were classified into the underestimated group (30 patients, 15.5%). Factors that were associated with underestimation of tumor depth were analyzed. Tumor size in the underestimated group was significantly larger; the lesions were more frequently located in the upper third of the stomach and were more histologically diffuse, scirrhous, with infiltrative growth, and more frequent lymphatic and venous invasion. For upper third lesions, in univariate analysis, histology (diffuse type) was associated with underestimation of tumor depth. Multivariate analysis found that tumor size (≥20 mm) and histology (diffuse type) were independently associated with underestimation of tumor depth. gastric cancer in the upper third of the stomach with diffuse type histology and >20 mm needs particular attention when considering the application of LPG.

Low-dose aspirin is known to cause upper gastrointestinal complications. The mechanism by which the aspirin disrupts gastric mucosal integrity remains to be clarified. In this study we investigated the temporal association of gastric secretory parameters (acid and mucus) with aspirin-induced gastropathy. In 42 long-term low-dose aspirin-takers and the same number of sex- and age-matched controls, pentagastrin-stimulated gastric juice was collected for 10 min during endoscopic examination. The collected gastric juice was divided and half was submitted to analysis for gastric acid (mEq/10 min) and the other half was analyzed for mucin (mg hexose/10 min) output. The grade of gastric mucosal injury was assessed endoscopically according to the modified Lanza score, and a score of more than 4 was defined as the presence of severe gastropathy. While gastric acid secretion did not differ significantly between aspirin-takers and controls, gastric mucus secretion, in terms of mucin output, was significantly increased in aspirin-takers compared to controls (4.1 (SD 4.8) vs. 2.3 (1.4) mg hexose/10 min, P < 0.05). Consequently, the acid/mucin ratio was significantly decreased in aspirin-takers compared to controls (1.2 (1.0) vs. 1.7 (1.4), P < 0.05). In the subanalysis of 25 aspirin-takers without severe gastropathy, gastric mucus secretion was increased and the acid/mucus ratio was decreased compared with controls, but there was no such association in the remaining 17 aspirin-takers with severe gastropathy. Overall, gastric mucus secretion is increased in aspirin-takers, suggesting a functional adaptive response to long-term administration of the drug. However, it is possible that the adaptive response is impaired in some aspirin takers, who might be susceptible to severe upper gastrointestinal complication.

To elucidate the clinicopathological characteristics of clinically early gastric cancer in the upper-third stomach and to clarify treatment precautions. A total of 683 patients with clinical early gastric cancer were enrolled in this retrospective study, 128 of whom had gastric cancer in the upper-third stomach (U group). All patients underwent a double contrast barium examination, endoscopy, and computed tomography (CT), and were diagnosed preoperatively based on the findings obtained. The clinicopathological features of these patients were compared with those of patients with gastric cancer in the middle- and lower-third stomach (ML group). We also compared clinicopathological factors between accurate-diagnosis and under-diagnosis groups in order to identify factors affecting the accuracy of a preoperative diagnosis of tumor depth. Patients in the U group were older (P = 0.029), had a higher ratio of males to females (P = 0.015), and had more histologically differentiated tumors (P = 0.007) than patients in the ML group. A clinical under-diagnosis occurred in 57 out of 683 patients (8.3%), and was more frequent in the U group than in the ML group (16.4% vs 6.3%, P < 0.0001). Therefore, the rates of lymph node metastasis and lymphatic invasion were slightly higher in the U group than in the ML group (P = 0.071 and 0.082, respectively). An under-diagnosis was more frequent in histologically undifferentiated tumors (P = 0.094) and in those larger than 4 cm (P = 0.024). The median follow-up period after surgery was 56 mo (range, 1-186 mo). Overall, survival and disease-specific survival rates were significantly lower in the U group than in the ML group (P = 0.016 and 0.020, respectively). However, limited operation-related cancer recurrence was not detected in the U group in the present study. Clinical early gastric cancer in the upper-third stomach has distinguishable characteristics that increase the risk of a clinical under-diagnosis, especially in patients with larger or undifferentiated tumors.

Gastric stump carcinoma was initially reported by Balfore in 1922, and many reports of this disease have since been published. We herein review previous reports of gastric stump carcinoma with respect to epidemiology, carcinogenesis, Helicobacter pylori (H. pylori) infection, Epstein-Barr virus infection, clinicopathologic characteristics and endoscopic treatment. In particular, it is noteworthy that no prognostic differences are observed between gastric stump carcinoma and primary upper third gastric cancer. In addition, endoscopic submucosal dissection has recently been used to treat gastric stump carcinoma in the early stage. In contrast, many issues concerning gastric stump carcinoma remain to be clarified, including molecular biological characteristics and the carcinogenesis of H. pylori infection. We herein review the previous pertinent literature and summarize the characteristics of gastric stump carcinoma reported to date.

Lean body mass loss after surgery, which decreases the compliance of adjuvant chemotherapy, is frequently observed in gastric cancer patients who undergo gastrectomy for gastric cancer. However, the risk factors for loss of lean body mass remain unclear. The current study retrospectively examined the patients who underwent curative gastrectomy for gastric cancer between June 2010 and March 2014 at Kanagawa Cancer Center. All the patients received perioperative care for enhanced recovery after surgery. The percentage of lean body mass loss was calculated by the percentile of lean body mass 1 month after surgery to preoperative lean body mass. Severe lean body mass loss was defined as a lean body mass loss greater than 5 %. Risk factors for severe lean body mass loss were determined by both uni- and multivariate logistic regression analyses. This study examined 485 patients. The median loss of lean body mass was 4.7 %. A lean body mass loss of 5 % or more occurred for 225 patients (46.4 %). Both uni- and multivariate logistic analyses demonstrated that the significant independent risk factors for severe lean body mass loss were surgical complications with infection or fasting (odds ratio [OR] 3.576; p = 0.001), total gastrectomy (OR 2.522; p = 0.0001), and gender (OR 1.928; p = 0.001). Nutritional intervention or control of surgical invasion should be tested in future clinical trials for gastric cancer patients with these risk factors to maintain lean body mass after gastrectomy.

Gastric lipoma presenting as a giant bulging mass in an oligosymptomatic patient: a case report

PubMed Central

2012-01-01

Introduction Lipomas of the gastrointestinal tract are a rare condition. Only 5% are of gastric origin, and this corresponds to 2% to 3% of all benign tumors of the stomach and less than 1% of all gastric neoplasms. It is our purpose to report an unusual presentation of a giant gastric lipoma in an oligosymptomatic patient and highlight the importance of discussing differential diagnosis in this situation. A review of the literature has shown that this is one of the largest gastric lipomas described. Case presentation We describe a rare case of a benign gastric tumor with uncommon features in a 63-year-old Caucasian woman. She was admitted with abdominal discomfort, nausea, and upper abdominal fullness after eating. The lesion was suspicious of malignancy because of its dimension and central contrast enhancement on computed tomography. Conventional upper digestive endoscopy revealed a large bulging mass in the gastric posterior wall and three ulcerated areas. In this procedure, a technical limitation due to the location of the mass in the submucosa prevented an adequate biopsy from being obtained. The fragments obtained from the ulcers revealed nothing but necrotic mucosa. Our patient underwent a subtotal gastrectomy and D1 lymphadenectomy with a Roux-en-Y reconstruction. Macroscopic findings revealed a 12 × 8 × 6cm mass with a volume of 576cm3, and the histological pattern demonstrated well-differentiated mature adipose tissue surrounded by a fibrous capsule, confirming the diagnosis of gastric submucosal lipoma. Conclusions Gastric lipoma is a rare benign disease that eventually simulates a malignant tumor. PMID:23006791

Background and study aims Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome caused by a germline mutation in the adenomatous polyposis coli (APC) gene, characterized by the presence of more than 100 adenomatous polyps in the colorectum. The upper gastrointestinal tract is an extracolonic site for malignancy in patients with FAP. The frequency of death in Japanese patients with FAP because of gastric cancer is 2.8 % and that because of colon cancer is 60.6 %. Few studies have reported upper gastrointestinal diseases in patients with FAP. In the present study, we investigated the clinical outcomes of patients with FAP diagnosed with gastric neoplasms. Patients and methods We enrolled 80 patients with FAP who underwent esophagogastroduodenoscopy from October 1997 to December 2011. We investigated patient characteristics, endoscopic findings of gastric lesions, treatment outcomes, and long-term courses. Results Fundic gland polyposis was observed in 51 patients (64 %) and gastric neoplasms in 22 patients (28 %), including 20 with non-invasive and 2 with invasive neoplasm. Of the 26 neoplasms, 11 were treated by endoscopic resection (ER) and 4 by surgical resection. Metachronous gastric neoplasms were observed in 7 patients (15 lesions) and treated by ER, except for in 1 patient. No patients died of gastric lesions during a median follow-up period of 6.5 years (range, 0 – 14). Conclusion Because gastric lesions including gastric cancers in patients with FAP did not cause any deaths, they can be considered to have favorable prognoses. Early detection of gastric neoplasms through an appropriate follow-up interval may have contributed to these good outcomes. PMID:28271094

Upper gastrointestinal bleeding refers to bleeding that arises from the gastrointestinal tract proximal to the ligament of Treitz. The primary reason for gastrointestinal bleeding associated with hepatocellular carcinoma is rupture of a varicose vein owing to pericardial hypotension. We report a rare case of gastrointestinal bleeding with hepatocellular carcinoma in a patient who presented with recurrent gastrointestinal bleeding. The initial diagnosis was gastric cancer with metastasis to the multiple lymph nodes of the lesser curvature. The patient underwent exploratory laparotomy, which identified two lesions in the gastric wall. Total gastrectomy and hepatic local excision was then performed. Pathological results indicated that the hepatocellular carcinoma had invaded the stomach directly, which was confirmed immunohistochemically. The patient is alive with a disease-free survival of 1 year since the surgery. Hepatocellular carcinoma with gastric invasion should be considered as a rare cause of upper gastrointestinal bleeding in hepatocellular carcinoma patients, especially with lesions located in the left lateral hepatic lobe. Surgery is the best solution.

Acute upper gastrointestinal bleeding (AUGIB) in cirrhotic patients occurs mainly from esophageal and gastric varices; however, quite a large number of cirrhotic patients bleed from other sources as well. The aim of the present work is to determine the prevalence of non-variceal UGIB as well as its different causes among the cirrhotic portal hypertensive patients in Nile Delta. Emergency upper gastrointestinal (UGI) endoscopy for AUGIB was done in 650 patients. Out of these patients, 550 (84.6%) patients who were proved to have cirrhosis were the subject of the present study. From all cirrhotic portal hypertensive patients, 415 (75.5%) bled from variceal sources (esophageal and gastric) while 135 (24.5%) of them bled from non-variceal sources. Among variceal sources of bleeding, esophageal varices were much more common than gastric varices. Peptic ulcer was the most common non-variceal source of bleeding. Non-variceal bleeding in cirrhosis was not frequent, and sources included peptic ulcer, portal hypertensive gastropathy, and erosive disease of the stomach and duodenum.

[Technical points of laparoscopic splenic hilar lymph node dissection--The original intention of CLASS-04 research design].

According to Japanese gastric cancer treatment guidelines, the standard operation for locally advanced upper third gastric cancer is the total gastrectomy with D2 lymphadenectomy, which includes the dissection of the splenic hilar lymph nodes. With the development of minimally invasive ideas and surgical techniques, laparoscopic spleen-preserving splenic hilar lymph node dissection is gradually accepted. It needs high technical requirements and should be carried out by surgeons with rich experience of open operation and skilled laparoscopic techniques. Based on being familiar with the anatomy of splenic hilum, we should choose a reasonable surgical approach and standardized operating procedure. A favorable left-sided approach is used to perform the laparoscopic spleen-preserving splenic hilar lymph node dissection in Department of Gastric Surgery, Fujian Medical University Union Hospital. This means that the membrane of the pancreas is separated at the superior border of the pancreatic tail in order to reach the posterior pancreatic space, revealing the end of the splenic vessels' trunk. The short gastric vessels are severed at their roots. This enables complete removal of the splenic hilar lymph nodes and stomach. At the same time, based on the rich clinical practice of laparoscopic gastric cancer surgery, we have summarized an effective operating procedure called Huang's three-step maneuver. The first step is the dissection of the lymph nodes in the inferior pole region of the spleen. The second step is the dissection of the lymph nodes in the trunk of splenic artery region. The third step is the dissection of the lymph nodes in the superior pole region of the spleen. It simplifies the procedure, reduces the difficulty of the operation, improves the efficiency of the operation, and ensures the safety of the operation. To further explore the safety of laparoscopic spleen-preserving splenic hilar lymph node dissection for locally advanced upper third gastric cancer, in 2016, we launched a multicenter phase II( trial of safety and feasibility of laparoscopic spleen-preserving No.10 lymph node dissection for locally advanced upper third gastric cancer (CLASS-04). Through the multicenter prospective study, we try to provide scientific theoretical basis and clinical experience for the promotion and application of the operation, and also to standardize and popularize the laparoscopic spleen-preserving splenic hilar lymph node dissection to promote its development. At present, the enrollment of the study has been completed, and the preliminary results also suggested that laparoscopic spleen-preserving No.10 lymph node dissection for locally advanced upper third gastric cancer was safe and feasible. We believe that with the improvement of standardized operation training system, the progress of laparoscopic technology and the promotion of Huang's three-step maneuver, laparoscopic spleen-preserving splenic hilar lymph node dissection will also become one of the standard treatments for locally advanced upper third gastric cancer.

Probably due to caffeine-induced gastric acid secretion, negative effects of coffee upon various upper-gastrointestinal diseases have been precariously accepted, despite the inadequate epidemiological evidence. Our aim is to evaluate the effect of coffee consumption on four major acid-related diseases: gastric ulcer (GU), duodenal ulcer (DU), reflux esophagitis (RE), and non-erosive reflux disease (NERD) based on the large-scale multivariate analysis. Of the 9,517 healthy adults, GU, DU, and RE were diagnosed by endoscopy, and NERD was diagnosed by the symptoms of heartburn and regurgitation without esophageal erosion. Associations between coffee consumption and the four disorders were evaluated, together with age, gender, body mass index (BMI), Helicobacter pylori (HP) infection status, pepsinogen I/II ratio, smoking, and alcohol. We further performed meta-analysis using the random effects model to redefine the relationship between coffee intake and peptic ulcer disease. The eligible 8,013 study subjects comprised of 5,451 coffee drinkers and 2,562 non-coffee drinkers. By univariate analysis, age, BMI, pepsinogen I/II ratio, smoking, and alcohol showed significant associations with coffee consumption. By multiple logistic regression analysis, positively correlated factors with significance were HP infection, current smoking, BMI, and pepsinogen I/II ratio for GU; HP infection, pepsinogen I/II ratio, and current smoking for DU; HP non-infection, male, BMI, pepsinogen I/II ratio, smoking, age, and alcohol for RE; younger age, smoking, and female for NERD. The meta-analyses could detect any association of coffee consumption with neither GU nor DU. In conclusion, there are no significant relationship between coffee consumption and the four major acid-related upper gastrointestinal disorders.

To estimate the potential systemic events during and after retinopathy of prematurity (ROP) screening. A prospective and descriptive designed study was conducted to detect the physiologic and pathological changes 24h before, during, and 72h after ROP screening. Control blood pressure (BP), saturation, pulse rate, and body temperature were routinely taken at various time internals before and after screening. Adverse effects pertain to cardiovascular system, respiratory system, gastric system, urinary system and nervous system were retrospect 0-72h after ROP screening at a 24-hour interval. Totally 1254 prematurity babies receiving ROP screening during Jan. 1(st) 2013 to Dec. 31(th) 2013 were enrolled in our survey. Compared to control vital sign data taken before the examination, there was a fluctuation in the diastolic BP with the increased 3.03 mm Hg (P=0.04) after 3 doses of mydriatic drops. Immediately after the examination, there was a further 12.64 mm Hg (P<0.01) increase in systolic BP and a 7.24 mm Hg (P<0.01) in diastolic BP. The mean pulse rate during examination was 22.4 bpm (P<0.01) higher than the 133.3±9.0 bpm control level. The oxygen saturation shared an average drop of 5% (P<0.01) during screening. In prematurity with postconceptional age less than 31wk, the incidence of apnea (23.5%), necrotizing enterocolitis (NEC) (8.7%), gastric residual (25.4%) and upper digestive tract hemorrhage (6.4%) also demonstrated a significant rise (P<0.01). In our study sample, ROP screening was associated with NEC, gastric residual and upper digestive tract hemorrhage. These gastrointestinal side effects, along with breath activity pattern change and vital signs indicators fluctuation, may be results of additional stress responses.

Myeloid sarcomas (MS) involve extramedullary blast proliferation from one or more myeloid lineages that replace the original tissue architecture, and these neoplasias are called granulocytic sarcomas, chloromas or extramedullary myeloid tumors. Such tumors develop in lymphoid organs, bones (e.g., skulls and orbits), skin, soft tissue, various mucosae, organs, and the central nervous system. Gastrointestinal (GI) involvement is rare, while the occurrence of myeloid sarcomas in patients without leukemia is even rare. Here, we report a case of a 38-year-old man who presented with epigastric pain and progressive jaundice. An upper GI endoscopy had shown extensive multifocal hyperemic fold thickening and the spread of nodular lesions in the body of the stomach. Biopsies from the gastric lesions indicated myeloid sarcoma of the stomach. However, concurrent peripheral blood and bone marrow examinations showed no evidence of acute myeloid leukemia. For diagnosis, the immunohistochemical markers must be checked when evaluating a suspected myeloid sarcoma case. Accurate MS diagnosis determines the appropriate therapy and prognosis. PMID:25717265

To evaluate, in a group of patients with long-standing type 1 diabetes (DM1), an association of dyspepsia symptoms with: changes in the gastroduodenal mucosa, infection by Helicobacter pylori, glycemic control, and psychological and nutritional factors. A total of 32 patient with DM1 were studied (age: 38 ± 9 years; females: 25; diabetes duration: 22 ± 5 years). All patients answered a standardized questionnaire for the evaluation of gastrointestinal symptoms and underwent upper gastrointestinal endoscopy, with gastric biopsies for the evaluation of Helicobacter pylori infection. The presence of anxiety and depression was evaluated by the HAD scale. Nutritional parameters were BMI, arm and waist circumference, skinfold measurement, and body fat percentage. Upper endoscopy detected lesions in the gastric mucosa in 34.4% of the patients, with similar frequency in those with (n = 21) and without dyspepsia (n = 11). The patients with dyspepsia complaints showed greater frequency of depression (60% vs. 0%; p = 0.001), higher values for HbA1c (9.6 ± 1.7 vs. 8.2 ± 1.3%; p = 0.01) and lower values for BMI (24.3 ± 4.1 vs. 27.2 ± 2.6 kg/m2; p = 0.02), body fat percentage (26.6 ± 6.2 vs. 30.8 ± 7.7%; p = 0.04), and waist circumference (78.7 ± 8 vs. 85.8 ± 8.1 cm; p = 0.02). No association was found between the symptoms and the presence of Helicobacter pylori. Dyspepsia symptoms in patients with long-standing DM1 were associated with glycemic control and depression, and they seem to negatively influence the nutritional status of these patients.

The increasing subspecialisation of general surgeons in their elective work may result in problems for the provision of expert care for emergency cases. There is very little evidence of the impact of subspecialism on outcomes following emergency major upper gastrointestinal surgery. This prospective study investigated whether elective subspecialism of general surgeon is associated with a difference in outcome following major emergency gastric surgery. Between February 1994 and June 2010, the data from all emergency major gastric procedures (defined as patients who underwent laparotomy within 12 hours of referral to the surgical service for bleeding gastroduodenal ulcer and/or undergoing major gastric resection) was prospectively recorded. The sub-specialty interest of operating surgeon was noted and related to post-operative outcomes. Over the study period, a total of 63 major gastric procedures were performed of which 23 (37%) were performed by specialist upper gastrointestinal (UGI) consultants. Surgery performed by a specialist UGI surgeon was associated with a significantly lower surgical complication (4% vs. 28% of cases; p=0.04) and in-patient mortality rate (22% vs. 50%; p=0.03). Major emergency gastric surgery has significantly better clinical outcomes when performed by a specialist UGI surgeon. These results have important implications for provision of an emergency general surgical service. Copyright© Acta Chirurgica Belgica.

Cases of gastric fistula secondary to drainage tube penetration have rarely been reported. The current study presents a case of gastric penetration caused by misplacement of a drainage tube after a splenectomy. The patient was admitted to the Department of Hepatobiliary Surgery, (Shaoxing People's Hospital, Shaoxing Hospital of Zhejiang University, Shaoxing, Zhejiang, China) for blunt abdominal trauma due to injuries sustained in an automobile accident. A ruptured spleen was found and successfully removed surgically. On post-operative day 7, the patient complained of slight discomfort and tenderness in the left upper quadrant of the abdomen. In addition, 500 ml of bile-colored fluid with small food particles was noted in the drainage tube. Barium X-ray revealed a gastric fistula in the upper gastrointestinal tract. Gastroscopy indicated infiltration of the drainage tube into the gastric cavity. No significant peritoneal effusion was observed, as revealed by abdominal ultrasound examination. These results confirmed the diagnosis of a gastric fistula secondary to perforation by the drainage tube. Following conservative treatment with antibiotics and total parenteral nutrition, the general condition of the patient improved significantly. The drainage tube was withdrawn progressively, as the amount of fluid being discharged was decreasing. Gastroenterography confirmed perforation closure and the tube was finally removed on post-operative day 44.

Primary gastric tumors are very rare in children. Burkitt lymphoma is a common type of non-Hodgkin's lymphoma, and gastric Burkitt lymphoma usually occurs in the aged. When involving the gastrointestinal tract, primary gastric Burkitt lymphoma is very rare in younger childhood. Many gastric lymphomas including mucosa-associated lymphoid tissue lymphoma are associated with Helicobacter pylori infection or acute bleeding symptom. We report a seven-year-old boy who presented with only some vomiting and postprandial pain. His upper gastrointestinal endoscopy and biopsy revealed a large primary Burkitt lymphoma with no acute bleeding and no evidence of H. pylori infection. After chemotherapy, he remains in remission.

A 68-year-old man was admitted to another hospital because of progressive weight decrease and appetite loss. Endoscopic examination revealed type 4 advanced gastric cancer at the upper body of the stomach. In February, 2003, he patient had probe laparotomy because there was a small amount of ascites in his peritoneal cavity, and intraoperative washing cytology revealed cancer cells in ascites.Subsequently, we started chemotherapy using S-1 and CPT-11. S-1 at a dose of 100 mg/day was orally administered for 2 weeks, and CPT-11 at a dose of 90 mg/body was intravenously administered once a week for 2 weeks followed by a 2-week drug-free period as 1 course. After 7 courses of the chemotherapy, the main lesion endoscopically vanished.Subsequently, the patient underwent curative total gastrectomy together with D2 lymph node dissection. Intraoperative cytology revealed no cancer cells, and histological examination of the primary lesion showed cancer cells invading the subserosa with no metastasis to any dissected lymph nodes. This therapy induced Grade 2 effect on cancer cells.Postoperatively, only S-1 was administered to the patient, who has remained alive with no recurrence for 4 years as of January, 2007.

Confocal LASER endomicroscopy (CLE) is a newly developed endoscopic technique which allows subsurface in vivo histological assessment during ongoing endoscopy and targeted biopsies. Ultrasound endoscopy (EUS) is a useful tool in staging upper GI malignant lesions. We describe for the first time the use of both techniques during the same endoscopic session, in a pilot study, in order to increase the diagnostic yield of histological assessment and provide the staging of the gastric neoplastic lesions thus decreasing the time to therapeutic decision. CLE has been performed with the Pentax EG-3870CIK confocal endomicroscope after a 5 ml intravenous 10% fluorescein injection; EUS has been performed subsequently, during the same endoscopic Propofol sedation session, using a standard radial EUS-scope. Eleven patients have been investigated, 4 females, 7 males, mean age 59.7 +/- 12.3 years. The indication of CLE/EUS exploration was the presence of a gastric polypoid lesion in 37% of cases, atypical gastric ulcer in 27% of patients, gastric lymphoma 18%, suspicion of gastric cancer recurrence after resection 9% and infiltrating type gastric cancer 9%. Histological assessment after targeted biopsy has established the diagnosis of gastric adenocarcinoma in 55% of cases, gastric lymphoma in 18% of cases, gastric adenoma, gastric GIST and gastric foveolar hyperplasia in 9% of cases respectively. CLE has allowed targeted biopsies in 81.8% of cases. In 2 patients - one case with suspected recurrent gastric cancer after surgery and one case of gastric lymphoma, CLE has indicated normal gastric mucosa. The EUS evaluation has shown TO lesion in two cases, T1 in 3 cases, T2 in 3 cases, T3 in one case. The EUS evaluation showed in one gastric lymphoma patient a lesion interesting the mucosa and submucosa with regional adenopathy and a submucosal lesion with regional adenopathy in the other gastric lymphoma case. The therapeutic decision was surgery in 73% of cases, chemotherapy and follow-up in 18% of cases and follow-up in 9% of cases. No complications were registered during the CLE/EUS explorations. CLE and EUS can be successfully associated during the same endoscopic session, for upper GI neoplastic lesions allowing targeted biopsies for histological assessment and disease staging for optimal therapeutic decision.

To study the effect of neoadjuvant chemotherapy on nutritional status in patients with locally advanced gastric cancer. Cases inclusion criteria: (1)18-65 years old; (2) Gastric cancer confirmed by gastroscopic biopsy; (3) Preoperative TNM stage III( according to the AJCC stage 2000 standard; (4) Kamosfsky functional status score> 60 points; (5)Receiving neoadjuvant chemotherapy voluntarily and signing the informed consent form. Case exclusion criteria: (1)Having contraindications of chemotherapy and surgery; (2) Suffering from heart, liver and kidney and other underlying diseases; (3) Concurrent with malignant diseases, wasting disease or other digestive diseases. According to the above criteria, clinical data of 73 patients of stage III( gastric cancer receiving neoadjuvant chemotherapy at Weifang People's Hospital from May 2015 to March 2017 were prospectively collected. The cohort study was adopted. After removing 3 patients who did not complete the chemotherapy, a total of 70 patients who completed the chemotherapy were included in the study. All the patients received SOX chemotherapy without nutritional support during chemotherapy. Changes of body composition and nutritional indicators were analyzed before and after chemotherapy, and according to the tumor regression after chemotherapy, patients were divided into response group (complete or sub-total tumor regression) and non-response group (tumor part, with or without a small amount of retreat) for stratified analysis. Of 70 gastric cancer patients, 40 were male and 30 were female with a age of (53.8±6.4) (28 to 64) years. There were 26 cases (37.1%) of stage III(a, 35 cases (50.0%) of stage III(b and 9 cases (12.9%) of stage III(c. There were 41 cases in response group and 29 cases in non-response group. Three patients (4.3%) were complete remission (CR) and 38 patients (54.3%) were partial remission (PR) in response group, while 23 cases (32.9%) were stable disease (SD) and 6 cases (8.6%) were progressive disease (PD). After neoadjuvant chemotherapy, the extracellular fluid of the whole patients increased from (13.3±1.7) L to (13.5±1.6) L (t=-2.044, P=0.045); the intracellular fluid decreased from (21.4±2.5) L to (21.1±2.4) L (t=2.369, P=0.021); the lymphocyte count decreased from (0.31±0.10)×10 9 /L to (0.29±0.10)×10 9 /L (t=1.706, P=0.009); the other indexes were not significantly different (all P>0.05). Stratified analysis showed that after neoadjuvant chemotherapy in response group, body mass increased from (60.1±8.8) kg to (61.0±8.3) kg (t=-2.773, P=0.008); body mass index increased from (21.9±2.4) kg/m 2 to (22.3±1.9) kg/m 2 (t=-3.479, P=0.001), while above two parameters did not differ significantly in non-response group. No significant differences in body mass, body mass index, skeletal muscle, inorganic salt, extracellular fluid, body fat, protein, upper arm circumference and intracellular fluid were found between two groups before and after neoadjuvant chemotherapy(all P>0.05). Except slight decrease in hemoglobin and lymphocyte, the other nutritional indicators were slightly elevated in response group, while the differences were not statistically significant(all P>0.05). All nutritional indicators in non-response group were slightly decreased without significant differences as well (all P>0.05). Neoadjuvant chemotherapy does not aggravate malnutrition in patients with locally advanced gastric cancer.

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.

The rarity of gastric abscess may be associated with the difficulty of early diagnosis and high mortality as a result. In general, subepithelial lesions (SELs) of the stomach are incidentally detected during the course of upper endoscopy without specific clinical symptoms and signs. However, some gastric SELs present rarely as a form of hemorrhage, obstruction, perforation, and abscess. Here we report a 45-year-old man with gastric SEL presenting as a gastric abscess, which was diagnosed as an ectopic pancreas of the stomach, along with a review of the literature. Although gastric SEL presenting as an abscess is known as a serious and life-threatening lesion, the patient made a complete recovery through surgical resection as well as medical treatment.

We present the case of a patient under study due to ascites in which a mass located on the gastric wall was observed during ultrasonography. Further studies (upper endoscopy and computed tomography) confirmed this finding. After an ultrasound-guided percutaneous biopsy, diagnosis of gastric schwannoma was made as intense S-100 expression was found. Surgery was rejected due to the bad clinical situation of the patient and because the mass was an asymptomatic benign tumor.

To raise awareness for surgeons encountering bariatric patients with anatomy that deviates from the standard Roux-en-Y gastric bypass (RYGB). This is a single-institution retrospective case series over 12 years (2003-2014) involving patients who believed they received RYGBs, but actually did not. Data was obtained reviewing physician encounters, imaging, and operative reports. There were six cases with confusing clinical pictures, found to have aberrant RYGB anatomy: (1) gastric bypass with jejuno-jejunostomy only without gastrojejunostomy, (2) distal partial vertical gastrectomy without expected prosthetic band, (3) inverse vertical banded gastroplasty, (4) non-divided gastric bypass with no gastrojejunostomy, (5) 20-cm Roux limb, with gastro-gastric fistula, and (6) 200-cm bilio-pancreatic limb similar to the traditional Scopinaro procedure. There are cases of "Roux-en-Y gastric bypasses" that have no resemblance to the named procedure at all. Adjunctive upper gastrointestinal studies and upper endoscopies help surgeons make diagnoses that are incongruent with the surgical history. It is important to keep in mind that there could be anatomic or surgical variations which were born out of necessity or based on other surgeons' creativities.

The timely detection of early gastric cancer (EGC) is important in performing endoscopic submucosal dissection (ESD). We attempted to determine the location characteristics of regions where EGC is frequently detected and analyzed the EGC characteristics associated with that location. We retrospectively reviewed the medical records of patients with EGC treated by ESD between November 2008 and August 2016. We retrospectively investigated and analyzed 647 EGC lesions. The patients' mean age was 66.7 ± 10.8 years. The patient population was predominantly male (77.1%, 499/647). A well-to-moderately differentiated carcinoma was observed in 97.2% of patients. The common site of carcinoma occurrence was the lower part of the stomach (the antrum and lower third of body, 89.6%). Among the stomach hemispheres, the lesser curvature side was the most frequent site of EGC (43.9%). The posterior side of EGC was more frequent than anterior side of EGC (20.4 vs. 15.6%, respectively). Submucosal invasive EGC was more frequent in the mid-to-upper parts of stomach than lower part of stomach (odds ratio 1.919; confidence interval 1.014-3.623; p = 0.045). Most EGCs that are resectable with ESD were found in the lower part and in the lesser curvature of the stomach. The submucosal invasive EGC was more frequent in the mid-to-upper part of stomach.

The motility of the upper gut after Roux-en-Y gastric bypass (RYGBP) is underexplored. We aimed to investigate the oesophago-gastro-Roux limb motor activity during fasting and after food intake. Eighteen morbidly obese patients were examined at least 2 years after RYGBP. A high-resolution manometry catheter was positioned to straddle the oesophagogastric junction, the gastric pouch and the proximal Roux limb using transmucosal potential difference measurements. Three patients with vertical banded gastroplasty (VBG) were also studied. During the fasting state, the gastric pouch had low or no activity whereas the Roux limb exhibited regular migrating motility complexes (MMCs) being initiated just distal to gastroenteroanastomosis. Median cycle duration was 72 min, and the median propagating velocity of the phase III MMC phase was 2.7 cm/min (n = 8). When patients were asked to eat until they felt comfortably full, intraluminal pressure increased by 6 to 8 cmH₂O without any significant difference between gastric pouch and the Roux limb (n = 9). The increased intraluminal pressure following food intake correlated neither to weight loss nor to meal size or rate of eating. A successful RYGBP is associated with MMC in the Roux limb during fasting. The gastric pouch and the Roux limb behaved as a common cavity during food ingestion. Data do not support the hypothesis that the alimentary limb pressure in response to food intake influences either meal size or weight loss.

Double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) is one of the most widely conducted gastric cancer screening methods. It has been executed to find gastric cancer, but has not been usually executed to detect premalignant atrophic mucosa of stomach. To understand the meaning of UGI-XR-based atrophic gastritis, we analyzed its association with several causative factors including Helicobacter pylori (HP) infection. We evaluated 6,901 healthy adults in Japan. UGI-XR-based atrophic gastritis was diagnosed based on the irregular shape of areae gastricae and its expansion in the stomach. Of the 6,433 subjects with no history of HP eradication and free from gastric acid suppressants, 1,936 were diagnosed as UGI-XR-based atrophic gastritis (mild: 234, moderate: 822, severe: 880). These were univariately associated with serum HP IgG and serum pepsinogen I/II ratio with statistical significance. The multiple logistic analysis calculating standardized coefficients (β) and odds ratio (OR) demonstrated that serum HP IgG (β = 1.499, OR = 4.48), current smoking (β = 0.526, OR = 1.69), age (β = 0.401, OR = 1.49), low serum pepsinogen I/II ratio (β = 0.339, OR = 1.40), and male gender (β = 0.306, OR = 1.36) showed significant positive association with UGI-XR-based atrophic gastritis whereas drinking and body mass index did not. Among the age/sex/smoking/drinking-matched 227 pairs derived from chronically HP-infected and successfully HP-eradicated subjects, UGI-XR-based atrophic gastritis was detected in 99.1% of the former but in only 59.5% of the latter subjects (p<0.0001). Contrastively, UGI-XR-based atrophic gastritis was detected in 13 of 14 HP-positive proton pump inhibitor users (92.9%) and 33 of 34 HP-positive histamine H2-receptor antagonist users (97.1%), which are not significantly different from gastric acid suppressant-free subjects. The presence of UGI-XR-based atrophic gastritis is positively associated with Helicobacter pylori infection, current smoking, age, decreased serum pepsinogen I/II ratio, and male gender. Eradication of Helicobacter pylori seems to superficially improve UGI-XR-based atrophic gastritis whereas intake of gastric acid suppressants does not.

In this study, we examined the physicochemical nature of sunflower seed oil bodies (in the absence and presence of added protein) exposed to gastrointestinal conditions in vitro: crude oil bodies (COB); washed oil bodies (WOB); whey protein isolate-enriched oil bodies (WOB-WPI); and, sodium caseinate enriched-oil bodies (WOB-SC). All oil body emulsions were passed through an in vitro digestion model that mimicked the stomach and duodenal environments, and their physicochemical properties were measured before, during, and after digestion. Oil bodies had a positive charge under gastric conditions because the pH was below the isoelectric point of the adsorbed protein layer, but they had a negative charge under duodenal conditions which was attributed to changes in interfacial composition resulting from adsorption of bile salts. Oil bodies were highly susceptible to flocculation and coalescence in both gastric and duodenal conditions. SDS-PAGE analysis indicated degradation of oleosin proteins (ca. 18-21 kDa) to a greater or lesser extent (dependent on the emulsion) during the gastric phase in all emulsions tested; there is evidence that some oleosin remained intact in the crude oil body preparation during this phase of the digestion process. Measurements of protein displacement from the surface of COBs during direct exposure to bile salts, without inclusion of a gastric phase, indicated the removal of intact oleosin from native oil bodies.

The highest cancer risks in familial adenomatous polyposis (FAP) include colorectal, duodenal, and thyroid for which surveillance is recommended. Nearly all patients with FAP have gastric fundic gland polyposis (FGP), but gastric cancers are rarely reported with a similar incidence as the general population. We describe a recent, sudden increase in the incidence of gastric cancer in FAP. Seven of the ten cases were diagnosed in the last 20 months. Comparing our population to the SEER database for gastric cancer, the standardized incidence ratio is 140. All cases arose in patients with a carpeting of FGP and associated with large mounds of proximal gastric polyps. Nearly all patients were under upper endoscopic surveillance. This is a concerning observation and reflects a change in the phenotypic presentation of FAP in Western patients.

Here, we report the case of a 77-year-old male patient who was revealed to have an unsuspected case of gastric adenocarcinoma with paravertebral plasmacytoma following biopsy. Plasmacytoma may be classified into two main groups: Multiple myeloma and plasmacytoma without marrow involvement. It comprises isolated plasmacytoma of the bone and extramedullary plasmacytoma. Extramedullary plasmacytoma (EMP) accounts for 3% of all plasmacytomas; however, ~80% are located in the upper respiratory tract and upper gastrointestinal tract. It occurs extremely rarely in paravertebral areas. Case reports of EMP and other types of malignant tumor occurring at the same time have not been identified in searches of the literature. In the present study, we describe the diagnosis and treatment process of a case of gastric adenocarcinoma concurrent with paravertebral plasmacytoma. It may be helpful for early clinical diagnosis and treatment of such cases. PMID:27446469

Background Some authors have studied the relationship between the presence of polyps, adenomas and cancers of upper gastrointestinal tract (stomach and duodenum) and risk of colorectal polyps and neoplasms; however, the results are controversial, which may be due to study sample size, populations, design, clinical features, and so on. No meta-analysis, which can be generalized to a larger population and could provide a quantitative pooled risk estimate of the relationship, of this issue existed so far. Methods We performed a meta-analysis to evaluate risk of colorectal polyps or neoplasms in patients with polyps, adenomas or cancers in upper gastrointestinal tract comparing with controls. A search was conducted through PubMed, EMBASE, reference lists of potentially relevant papers, and practice guidelines up to 27 November 2013 without languages restriction. Odd ratios (ORs) were pooled using random-effects models. Results The search yielded 3 prospective and 21 retrospective case-control studies (n = 37152 participants). The principal findings included: (1) OR for colorectal polyps was 1.15 (95% CI, 1.04–1.26) in the gastric polyps group comparing with control groups; (2) Patients with gastric polyps and neoplasms have higher risk (OR, 1.31 [95% CI, 1.06–1.62], and 1.72 [95% CI, 1.42–2.09], respectively) of colorectal neoplasms comparing with their controls; and (3) Positive association was found between the presence of colorectal neoplasms and sporadic duodenal neoplasms (OR, 2.59; 95% CI, 1.64–4.11). Conclusions Findings from present meta-analysis of 24 case-control studies suggest that the prevalence of colorectal polyps was higher in patients with gastric polyps than in those without gastric polyps, and the risk of colorectal neoplasms increases significantly in patients with gastric polyps, neoplasms, and duodenal neoplasms. Therefore, screening colonoscopy should be considered for patients with upper gastrointestinal polyps and neoplasms. PMID:24637723

The aim of lymphadenectomy is to clear all the metastatic nodes achieving a complete removal of the tumor; nevertheless, its role in gastric cancer has been very much debated. The frequency of node metastasis in each lymphatic station according to the International Gastric Cancer Association, was studied in 545 patients who underwent D2 or D3 lymphadenectomy from June 1988 to December 2002. Upper third early cancers have shown an involvement of N2 celiac nodes in 25%. In advanced cancers, there was a high frequency of metastasis in the right gastroepiploic (from 10% in T2 to 50% in T4) and in the paraaortic nodes (26% in T2, 32% in T3, 38 % in T4). N3 left paracardial nodes involvement was observed in an important share of middle third tumors (17% in T3, 36% in T4). Splenic hilum nodes metastasis were common in T3 and T4 cancers located in the upper (39%) and middle (17%) stomach. N2 nodal involvement was frequent in lower third advanced cancers. Metastasis in M left paracardial and short gastric nodes were observed in a small percentage of cases. Given the nodal diffusion in our gastric cancer patients, extended lymphadenectomy is still a rationale to obtain radical resection.

Upper gastrointestinal cancers contribute significantly to cancer-related morbidity and mortality in sub-Saharan Africa, but they continue to receive limited attention. The high incidence in young adults remains unexplained, and the risk factors have not been fully described. A literature search was conducted using the electronic database PubMed. Beginning from January 1980 to February 2016, all articles evaluating biomass smoke exposure with oesophageal and gastric cancer were reviewed. Over 70% of the African population relies on biomass fuel, meaning most Africans are exposed to biomass smoke throughout their lives. Cigarette smoke is an established risk factor for upper gastrointestinal cancers, and some of its carcinogenic constituents are also present in biomass smoke. We found eight case-control studies reporting associations between exposure to biomass smoke and oesophageal cancer, and two linking biomass smoke to gastric cancer. All of these papers reported significant positive associations between exposure and cancer risk. Further research is needed in order to fully define the constituents of biomass smoke, which could each have varying specific and synergistic or independent contributions to the development of upper gastrointestinal cancers. Exposure to biomass smoke is an environmental factor influencing the development of upper gastrointestinal cancers, especially in low-resource settings.

Higher morbidity in total gastrectomy than in distal gastrectomy has been reported, but laparoscopic subtotal gastrectomy (LsTG) has been reported to be safe and feasible in early gastric cancer (GC). We determined the surgical, nutritional and oncological outcomes of LsTG for advanced gastric cancer (AGC). Of the 816 consecutive patients with GC who underwent radical gastrectomy at our institution between 2008 and 2012, 253 who underwent curative laparoscopic gastrectomy (LG) for AGC were enrolled. LsTG was indicated for patients with upper stomach third tumors, who hoped to avoid total gastrectomy, <4 cm to the esophagogastric junction and a 2-cm proximal margin with cut end negative in frozen section, whereas laparoscopic conventional distal gastrectomy (LcDG) and laparoscopic total gastrectomy (LTG) were performed otherwise. Surgical outcomes and postoperative nutritional status were primarily assessed. Of 253 patients, the morbidity (Clavien-Dindo classification grade ≥ III) was 17.0% (43 patients). The 3-year overall survival and 3-year recurrence-free survival rates were 80.2 and 73.5%, respectively. LcDG, LsTG and LTG were performed in 121, 27 and 105 patients, individually. Morbidity was strongly associated with LTG (P = 0.001). Postoperative loss of body weight was significantly greater after LTG in comparison with LcDG or LsTG (P < 0.001). No difference in morbidity and postoperative loss of body weight were observed between LcDG and LsTG group. LG for AGC was feasible and safe surgically and oncologically. LsTG for AGC may be safer than LTG from surgical and postoperative nutritional point of view.

The choice of the type of surgical treatment used in gastric cancer, in cases where it is possible to operate in relation to the extent of cancer, raises the question of whether the surgeon should perform a total exeresis of the organ, even in cases where the tumour is located in the 3rd distal of the stomach. A retrospective study was carried out on patients admitted to the Surgical Department of the University of Perugia between January 1963 and December 1988. Having rejected 123 cases because of incomplete data or insufficient follow-up, 1.140 cases were selected from a total of 1.263 patients. The sites of neoplasia were as follows: terminal esophagus: 1.76% of cases; cardia: 6.67%; fornix of the stomach: 9.37%; the body of the stomach and lesser curvature: 23.65%; body of the stomach (other portions): 10.07%; angulus: 3.63%; gastric antrum: 37.82%, pylorus: 4.45%; the remaining 2.58% showed a diffuse form involving two or more the above parts. The subdivision of the cases into stages, using the TNM classification, revealed the following groupings: 7.04% of patients were first observed at stage I, 20.70% at stage II, 42.04% at stage III and 30.20% at stage IV. From the above figures it is evident that radical surgical was indicated only in some of the patients observed. The prognostic factors examined in the comparative study of different tumour sites were: age, sex, macroscopic and histological tumour type, size, infiltration of neoplasia through gastric wall coat, lymph node and/or systemic diffusion.(ABSTRACT TRUNCATED AT 250 WORDS)

Purpose: The aim of this study was to assess the tolerance dose of gastric mucosa for single-fraction computed tomography (CT)-guided, high-dose-rate (HDR) brachytherapy of liver malignancies. Methods and Materials: A total of 33 patients treated by CT-guided HDR brachytherapy of liver malignancies in segments II and/or III were included. Dose planning was performed upon a three-dimensional CT data set acquired after percutaneous applicator positioning. All patients received gastric protection post-treatment. For further analysis, the contours of the gastric wall were defined in every CT slice using Brachyvision Software. Dose-volume histograms were calculated for each treatment and correlated with clinical datamore » derived from questionnaires assessing Common Toxicity Criteria (CTC). All patients presenting symptoms of upper GI toxicity were examined endoscopically. Results: Summarizing all patients the minimum dose applied to 1 ml of the gastric wall (D{sub 1ml}) ranged from 6.3 to 34.2 Gy; median, 14.3 Gy. Toxicity was present in 18 patients (55%). We found nausea in 16 (69%), emesis in 9 (27%), cramping in 13 (39%), weight loss in 12 (36%), gastritis in 4 (12%), and ulceration in 5 patients (15%). We found a threshold dose D{sub 1ml} of 11 Gy for general gastric toxicity and 15.5 Gy for gastric ulceration verified by an univariate analysis (p = 0.01). Conclusions: For a single fraction, small volume irradiation we found in the upper abdomen a threshold dose D{sub 1ml} of 15.5 Gy for the clinical endpoint ulceration of the gastric mucosa. This in vivo assessment is in accordance with previously published tolerance data.« less

To investigate the early upper gastrointestinal endoscopy (endoscopy) significantly reduces mortality resulting from upper gastrointestinal (GI) bleeding. Upper GI bleeding was defined as 1a, 1b, 2a, and 2b according to the Forrest classification. The hemoglobin (Hb), and C-reactive protein (CRP) were examined at around the day of endoscopy and 3 mo prior to endoscopy. The rate of change was calculated as follows: (the result of blood examination on the day of endoscopy - the results of blood examination 3 mo prior to endoscopy)/(results of blood examination 3 mo prior to endoscopy). Receiver operating characteristic curves were created to determine threshold values. Seventy-nine men and 77 women were enrolled. There were 17 patients with upper GI bleeding: 12 with a gastric ulcer, 3 with a duodenal ulcer, 1 with an acute gastric mucosal lesion, and 1 with gastric cancer. The area under the curve (AUC), threshold, sensitivity, and specificity of Hb around the day of endoscopy were 0.902, 11.7 g/dL, 94.1%, and 77.1%, respectively, while those of CRP were 0.722, 0.5 mg/dL, 70.5%, and 73%, respectively. The AUC, threshold, sensitivity, and specificity of the rate of change of Hb were 0.851, -21.3%, 76.4%, and 82.6%, respectively, while those of CRP were 0.901, 100%, 100%, and 82.5%, respectively. Predictors for upper GI bleeding were Hb < 11.7 g/dL, reduction rate in the Hb > 21.3% and an increase in the CRP > 100%, 3 mo before endoscopy.

Endoscopic hemostasis is a useful treatment modality for gastric ulcer bleeding. However, it is sometimes difficult to achieve hemostasis in cases with arterial bleeding, especially those complicated with vascular abnormalities. We describe a case with gastric ulcer bleeding from a variant left gastric artery accompanied by congenital absence of the splenic artery. A 50-year-old female was admitted to our hospital with dizziness and tarry stools. Upper gastrointestinal endoscopy revealed bleeding from a gastric ulcer, and endoscopic hemostasis by endoscopic clipping was carried out. Computed tomography and abdominal angiography revealed the variant left gastric artery running below the gastric ulcer. In spite of endoscopic hemostasis and medication, re-bleeding from the gastric ulcer occurred. A transcatheter coil embolization for the variant left gastric artery was performed and successfully achieved hemostasis. This case was accompanied by congenital absence of the splenic artery, which is an extremely rare condition. We herein describe this rare case and review previously reported cases.

The fibronectin type III domain-containing protein 5 (FNDC5) discovered in 2002 has recently gained attention due to its potential role in protecting against obesity. In rat, no data exist regarding FNDC5 production and regulation in the stomach. The aim of the present work was to determine the expression of FNDC5 in the rat stomach and its potential regulation by body composition. The present data shows FNDC5 gene expression in the gastric mucosa. Immunohistochemical studies found FNDC5 immunopositivity in chief cells of gastric tissue. By the use of three different antibodies FNDC5 was found expressed in gastric mucosa and secreted by the stomach. The rate of gastric FNDC5 secretion parallels the circulating levels of FNDC5. The body fat mass increase after intervention with high fat diet coincided with a decrease in the secretion of FNDC5 from the stomach and a diminution in the FNDC5 circulating levels. In summary, the present data shows, for the first time, the expression of FNDC5 in the stomach of rats and its regulation by body composition, suggesting a potential role of gastric FNDC5 in energy homeostasis.

We present a case of a 56-year-old man with 3 synchronous gastric tumors. The patient presented with melena, and 3 gastric abnormalities were detected on gastroduodenoscopic examination, including a small ulcerative lesion in the gastric antrum, a submucosal mass in the gastric body, and severe erosion in the fundus. Histological examination of biopsy samples yielded respective diagnoses of gastric adenocarcinoma, gastritis, and mucosa-associated lymphoid tissue (MALT) lymphoma. The patient first received medication to eradicate any underlying Helicobacter pylori infection, which might have been a cause of the MALT lymphoma. Four weeks later, after examination of repeat biopsy samples revealed that the MALT lymphoma had resolved, the patient underwent subtotal gastrectomy. Further histological examination of resected tissue confirmed the antrum lesion as adenocarcinoma and the body lesion as schwannoma. To our knowledge, this is the first reported case of synchronous triple primary gastric adenocarcinoma, MALT lymphoma, and schwannoma.

An 81-year-oldwoman with advancedgastric cancer was referredto our hospital. Preoperative contrast-enhancedCT revealeda roundcalcification of the splenic hilum with 15mm in diameter as a splenic artery aneurysm. She underwent transcatheter arterial embolization(TAE)for the splenic artery aneurysm. Celiac artery angiography showedcollateral arterial network of the spleen from left gastric artery. Surgery for the gastric cancer was performed1 4 days after TAE. We cut the right gastric andbilateral epigastric arteries. After the left gastric artery clamping, we performedintraoperative indocyanine green(ICG)fluorography. ICG fluorography confirmedthat the bloodflow of the upper thirdof the stomach andspleen were maintained. We safely performed distal gastrectomy, and the postoperative course was uneventful.

The etiology of gastric cancer is multifactorial. Marked differences in the incidence of gastric cancer among different ethnic groups living in the same geographical area have been observed. This study looked at ethnic and dietary factors in patients with gastric cancer diagnosed at a tertiary referral centre in Sikkim over a period of one year. Patients of 60 years and above were included in the study and divided into four ethnic groups : Bhutias, Lepchas, Rais and other groups. 211 cases underwent upper GI endoscopy and 32 were diagnosed to have gastric cancer. Gastric cancer incidence was highest in Bhutia ethnic group. A trend towards higher intake of smoked meats, fermented vegetables, salt tea, and H.pylori positivity in the Bhutia ethnic group was associated with higher incidence of gastric cancer as compared to other ethnic groups. The study with a referral centre bias showed that Bhutia ethnic group had a higher incidence of gastric cancer as compared to other ethnic groups.

Upper gastrointestinal bleeding (UGIB) is a common emergency medical condition that may require hospitalization and resuscitation, and results in high patient morbidity. Upper gastrointestinal endoscopy is the preferred investigative procedure for UGIB because of its accuracy, low rate of complication, and its potential for therapeutic interventions. To determine the endoscopic findings in patients presenting with UGIB and its frequency among these patients according to gender and age in Lacor hospital, northern Uganda. The study was carried out at Lacor hospital, located at northern part of Uganda. The record of 224 patients who underwent endoscopy for upper gastrointestinal bleeding over a period of 5 years between January 2006 and December 2010 were retrospectively analyzed. A total of 224 patients had endoscopy for UGIB which consisted of 113 (50.4%) males and 111 (49.6%) females, and the mean age was 42 years ± SD 15.88. The commonest cause of UGIB was esophagealvarices consisting of 40.6%, followed by esophagitis (14.7%), gastritis (12.6%) and peptic ulcer disease (duodenal and gastric ulcers) was 6.2%. The malignant conditions (gastric and esophageal cancers) contributed to 2.6%. Other less frequent causes of UGIB were hiatus hernia (1.8), duodenitis (0.9%), others-gastric polyp (0.4%). Normal endoscopic finding was 16.1% in patients who had UGIB. Esophageal varices are the commonest cause of upper gastrointestinal bleeding in this environment as compared to the west which is mainly peptic ulcer disease.

Gastric carcinoma is a common malignant disease associated with an unfavorable prognosis in the case of late dia-gnosis. The most significant precancerous condition is chronic atrophic gastritis and intestinal metaplasia caused by Helicobacter pylori infection. These longlasting changes may lead to formation of dysplastic precancerous lesions. Upper endoscopy and histologic examination of forceps bio-psy specimens play a key role in the dia-gnosis of gastric precancerous conditions and lesions. Helicobacter pylori eradication therapy and endoscopic surveillance are main therapeutic modalities of gastric precancerous conditions. Localized precancerous lesions and early gastric neoplasia without the risk of lymphatic spread could be cured by means of endoscopic resection techniques.

Is screening and surveillance for early detection of gastric cancer needed in Korean Americans?

PubMed Central

Kim, Gwang Ha; Bang, Sung Jo; Ende, Alexander R.; Hwang, Joo Ha

2015-01-01

The incidence rate of gastric cancer in Korean Americans is over five times higher than that in non-Hispanic whites, and is similar to the incidence of colorectal cancer in the overall United States population. In Korea, the National Cancer Screening Program recommends endoscopy or upper gastrointestinal series for people aged 40 years and older every 2 years. However, the benefit of gastric cancer screening in Korean Americans has not been evaluated. Based on epidemiologic studies, Korean Americans appear to have more similar gastric cancer risk factors to Koreans as opposed to Americans of European descent, though the risk of gastric cancer appears to decrease for subsequent generations. Therefore, in accordance with recent recommendations regarding screening for gastric cancer in Korea, endoscopic screening for gastric cancer in Korean Americans should be considered, especially in those with known atrophic gastritis/intestinal metaplasia or a family history of gastric cancer. In the future, additional studies will needed to assess whether a screening program for gastric cancer in Korean Americans will result in a survival benefit. PMID:26552450

The gastric mucosa of dogs is often colonized by non-Helicobacter pylori helicobacters (NHPH), while H. pylori is the predominant gastric Helicobacter species in humans. The colonization of the human gastric mucosa by H. pylori is highly dependent on the recognition of host glycan receptors. Our goal was to define the canine gastric mucosa glycophenotype and to evaluate the capacity of different gastric Helicobacter species to adhere to the canine gastric mucosa. The glycosylation profile in body and antral compartments of the canine gastric mucosa, with focus on the expression of histo-blood group antigens was evaluated. The in vitro binding capacity of FITC-labeled H. pylori and NHPH to the canine gastric mucosa was assessed in cases representative of the canine glycosylation pattern. The canine gastric mucosa lacks expression of type 1 Lewis antigens and presents a broad expression of type 2 structures and A antigen, both in the surface and glandular epithelium. Regarding the canine antral mucosa, H. heilmannii s.s. presented the highest adhesion score whereas in the body region the SabA-positive H. pylori strain was the strain that adhered more. The canine gastric mucosa showed a glycosylation profile different from the human gastric mucosa suggesting that alternative glycan receptors may be involved in Helicobacter spp. binding. Helicobacter pylori and NHPH strains differ in their ability to adhere to canine gastric mucosa. Among the NHPH, H. heilmannii s.s. presented the highest adhesion capacity in agreement with its reported colonization of the canine stomach. © 2014 John Wiley & Sons Ltd.

AIM To systematically review the syndrome of giant gastric lipomas, report 2 new illustrative cases. METHODS Literature systematically reviewed using PubMed for publications since 1980 with following medical subject heading/keywords: (“giant lipoma”) AND (“gastric”) OR [(“lipoma”) and (“gastric”) and (“bleeding”)]. Two authors independently reviewed literature, and decided by consensus which articles to incorporate. Computerized review of pathology/endoscopy records at William Beaumont Hospitals, Royal Oak and Troy, Michigan, January 2005-December 2015, revealed 2 giant gastric lipomas among 117110 consecutive esophagogastroduodenoscopies (EGDs), which were thoroughly reviewed, including re-review of original endoscopic photographs, radiologic images, and pathologic slides. RESULTS Giant gastric lipomas are extremely rare: 32 cases reported since 1980, and 2 diagnosed among 117110 consecutive EGDs. Average patient age = 54.5 ± 17.0 years old (males = 22, females = 10). Maximal lipoma dimension averaged 7.9 cm ± 4.1 cm. Ulcerated mass occurred in 21 patients. Lipoma locations: antrum-17, body-and-antrum-4, antrum-intussuscepting-into-small-intestine-3, body-2, fundus-1, and unspecified-5. Intramural locations included submucosal-22, subserosal-2, and unspecified-8. Presentations included: acute upper gastrointestinal (UGI) bleeding-19, abdominal pain-5, nausea/vomiting-5, and asymptomatic-3. Symptoms among patients with UGI bleeding included: weakness/fatigue-6, abdominal pain-4, nausea/vomiting-4, early-satiety-3, dizziness-2, and other-1. Their hemoglobin on admission averaged 7.5 g/dL ± 2.8 g/dL. Patients with GI bleeding had significantly more frequently ulcers than other patients. EGD was extremely helpful diagnostically (n = 31 patients), based on characteristic endoscopic findings, including yellowish hue, well-demarcated margins, smooth overlying mucosa, and endoscopic cushion, tenting, or naked-fat signs. However, endoscopic mucosal biopsies were mostly non-diagnostic (11 of 12 non-diagnostic). Twenty (95%) of 21 abdominal CTs demonstrated characteristic findings of lipomas, including: well-circumscribed, submucosal, and homogeneous mass with attenuation of fat. Endoscopic-ultrasound showed characteristic findings in 4 (80%) of 5 cases: hyperechoic, well-localized, mass in gastric-wall-layer-3. Transabdominal ultrasound and UGI series were generally less helpful. All 32 patients underwent successful therapy without major complications or mortality, including: laparotomy and full-thickness gastric wall resection of tumor using various surgical reconstructions-26; laparotomy-and-enucleation-2; laparoscopic-transgastric-resection-2; endoscopic-mucosal-resection-1, and other-1. Two new illustrative patients are reported who presented with severe UGI bleeding from giant, ulcerated, gastric lipomas. CONCLUSION This systematic review may help standardize the endoscopic and radiologic evaluation and therapy of patients with this syndrome. PMID:28852321

[Acute gastric volvulus: late complication of Nissen fundoplication. Report of two cases and review of the literature].

PubMed

Reyes-Zamorano, Jesús

2014-01-01

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.

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.

The aim of this study is to evaluate the results of routine and selective postoperative upper gastrointestinal series (UGIS) after Roux-en-Y gastric bypass (RYGB) for morbid obesity in different published series to assessing its utility and cost-effectiveness. A search in PubMed's MEDLINE was performed for English-spoken articles published from January 2002 to December 2012. Keywords used were upper GI series, RYGB, and obesity. Only cases of anastomotic leaks were considered. A total of 22 studies have been evaluated, 15 recommended a selective use of postoperative UGIS. No differences in leakage detection or in clinical benefit between routine and selective approaches were found. Tachycardia and respiratory distress represent the best criteria to perform UGIS for early diagnosis of anastomotic leak after a RYGB.

Background Wireless motility capsule (WMC) findings are incompletely defined in suspected gastroparesis. We aimed to characterize regional WMC transit and contractility in relation to scintigraphy, etiology, and symptoms in patients undergoing gastric emptying testing. Methods A total of 209 patients with gastroparesis symptoms at NIDDK Gastroparesis Consortium centers underwent gastric scintigraphy and WMCs on separate days to measure regional transit and contractility. Validated questionnaires quantified symptoms. Key Results Solid scintigraphy and liquid scintigraphy were delayed in 68.8% and 34.8% of patients; WMC gastric emptying times (GET) were delayed in 40.3% and showed 52.8% agreement with scintigraphy; 15.5% and 33.5% had delayed small bowel (SBTT) and colon transit (CTT) times. Transit was delayed in ≥2 regions in 23.3%. Rapid transit was rarely observed. Diabetics had slower GET but more rapid SBTT versus idiopathics (P ≤ .02). GET delays related to greater scintigraphic retention, slower SBTT, and fewer gastric contractions (P ≤ .04). Overall gastroparesis symptoms and nausea/vomiting, early satiety/fullness, bloating/distention, and upper abdominal pain subscores showed no relation to WMC transit. Upper and lower abdominal pain scores (P ≤ .03) were greater with increased colon contractions. Constipation correlated with slower CTT and higher colon contractions (P = .03). Diarrhea scores were higher with delayed SBTT and CTT (P ≤ .04). Conclusions & Inferences Wireless motility capsules define gastric emptying delays similar but not identical to scintigraphy that are more severe in diabetics and relate to reduced gastric contractility. Extragastric transit delays occur in >40% with suspected gastroparesis. Gastroparesis symptoms show little association with WMC profiles, although lower symptoms relate to small bowel or colon abnormalities. PMID:28872760

Laparoscopic adjustable gastric banding (LAGB) effectively treats morbid obesity and yields improved quality of life with low morbidity and mortality rates. The current standard of care is to perform a postoperative gastrographin study. This study evaluated a series of patients to determine the usefulness of this routine procedure. Retrospective analysis. Texas Tech University Health Sciences Center, Lubbock. A series of 100 patients who had undergone LAGB between August 1, 2006, and February 28, 2007, were evaluated by medical record review and a blinded examination of the upper gastrointestinal tract. Laboratory test results and patient vital signs. The mean age of the patients was 42 years. The mean initial body mass index (calculated as weight in kilograms divided by height in meters squared) was 50.0. Median excess weight loss was 49.0% after 12 months. Three patients did not undergo gastrographin studies because of a history of allergic reactions to the dye. No differences between the opinion of the surgeon and that of the original radiologist were uncovered. The 97 patients who underwent gastrographin studies lacked leaks; the only radiologic abnormalities were slow passage and reflux in 23 patients. No alteration in patient care resulted. The total cost for the 97 patients was $49 470. The 95% confidence interval for 0 useful results for 97 studies is 0.00 to 0.03; at best, 3.2% of patients undergoing this expensive study would have garnered some benefit. Routine postoperative upper gastrointestinal tract studies are expensive and of limited value. Instead of relying on them to detect leaks, which are extremely rare after LAGB, reliance should be given to the presence or absence of tachypnea and tachycardia, as is currently done for Roux-en-Y gastric bypass. In this way there will be a cost savings and the potential to make LAGB a same-day procedure.

There is no consensus as to which bariatric procedure is preferred to reduce weight and improve health in patients with a body mass index higher than 50. To compare 5-year outcomes after Roux-en-Y gastric bypass (gastric bypass) and biliopancreatic diversion with duodenal switch (duodenal switch). Randomized clinical open-label trial at Oslo University Hospital, Oslo, Norway, and Sahlgrenska University Hospital, Gothenburg, Sweden. Participants were recruited between March 17, 2006, and August 20, 2007, and included 60 patients aged 20 to 50 years with a body mass index of 50 to 60. The current study provides the 5-year follow-up analyses by intent to treat, excluding one participant accepted for inclusion who declined being operated on prior to knowing to what group he was randomized. Laparoscopic gastric bypass and laparoscopic duodenal switch. Body mass index and secondary outcomes including anthropometric measures, cardiometabolic risk factors, pulmonary function, vitamin status, gastrointestinal symptoms, health-related quality of life, and adverse events. Sixty patients were randomly assigned and operated on with gastric bypass (n = 31) and duodenal switch (n = 29). Fifty-five patients (92%) completed the study. Five years after surgery, the mean reductions in body mass index were 13.6 (95% CI, 11.0-16.1) and 22.1 (95% CI, 19.5-24.7) after gastric bypass and duodenal switch, respectively. The mean between-group difference was 8.5 (95% CI, 4.9-12.2; P < .001). Remission rates of type 2 diabetes mellitus and metabolic syndrome and changes in blood pressure and lung function were similar between groups. Reductions in total cholesterol, low-density lipoprotein cholesterol, triglycerides, and fasting glucose were significantly greater after duodenal switch compared with gastric bypass. Serum concentrations of vitamin A and 25-hydroxyvitamin D were significantly reduced after duodenal switch compared with gastric bypass. Duodenal switch was associated with more gastrointestinal adverse effects. Health-related quality of life was similar between groups. Patients with duodenal switch underwent more surgical procedures related to the initial procedure (13 [44.8%] vs 3 [9.7%] patients; P = .002) and had significantly more hospital admissions compared with patients with gastric bypass. In patients with a body mass index of 50 to 60, duodenal switch resulted in greater weight loss and greater improvements in low-density lipoprotein cholesterol, triglyceride, and glucose levels 5 years after surgery compared with gastric bypass while improvements in health-related quality of life were similar. However, duodenal switch was associated with more surgical, nutritional, and gastrointestinal adverse effects. clinicaltrials.gov Identifier: NCT00327912.

We report a case of gastric bezoar-induced gastric outlet obstruction that was successfully treated with a combination of endoscopic injection and irrigation with Coca Cola. A 73-year-old diabetic woman had a history of perforated peptic ulcer and had received pyloroplasty more than 20 years previously. She had been ingesting Pho Pu Zi (Cordia dichotoma Forst. f.) as an appetizer for 1 month. She presented with epigastric pain, nausea, and vomiting. Upper gastrointestinal endoscopy, performed at a local hospital, showed 2 gastric bezoars in the stomach, and 1 of them impacted at the pylorus. She was referred to our emergency department for removal of the gastric bezoars that were suspected to be causing gastric outlet obstruction. All attempts at endoscopic removal using a polypectomy snare, biopsy forceps and Dormia basket failed. We then injected Coca Cola directly into the bezoar mass, followed by irrigation with Coca Cola. Follow-up endoscopy was performed the next day, which revealed that the gastric bezoars had dissolved spontaneously.

The aim of this study is to report our six-year experience with portal-endocrine and gastric-exocrine drainage technique of pancreatic transplantation, which was first developed and implemented at our center in 2007. In this study, the outcomes of all patients at our center who had pancreas transplantation with portal-endocrine and gastric-exocrine drainage technique were evaluated. From October 2007 to November 2013, 38 patients had pancreas transplantation with this technique - 31 simultaneous kidney pancreas and seven pancreas alone. Median duration of follow-up was 3.8 years. One-, three-, and five-year patient and graft survival rates were 94%, 87%, 70% and 83%, 65%, 49%, respectively. For pancreas allograft dysfunction evaluation, 51 upper endoscopies were performed in 14 patients; donor duodenal biopsies were successfully obtained in 45 (88%). We detected nine episodes of acute rejection (eight patients) and seven episodes of cytomegalovirus (CMV) duodenitis (six patients). No patient developed any complication due to upper endoscopy. Portal-endocrine and gastric-exocrine drainage technique of pancreas transplantation provides lifelong easy access to the transplanted duodenum for evaluation of pancreatic allograft dysfunction.

This study was performed to investigate the effect of gastric banding surgery on the improvement of glycated hemoglobin (HbA 1c ) of morbidly obese (MO) patients with type 2 diabetes mellitus (T2DM) with the consideration that obesity was associated with insulin resistance and T2DM. We retrospectively reviewed the medical records of 38 MO with T2DM patients and 50 MO patients. Pre-surgery and post-surgery data were analyzed a year later. The medical data from these patients, including sex, age, height, weight, body composition, HbA 1c , triglyceride, total cholesterol, aspartate transaminase (AST), and alanine transaminase (ALT) were measured. There were significant reductions of body weight and body mass index (BMI), body fat, body fat percentage, waist-hip ratio, visceral fat, and obesity in each group before and after gastric banding surgery. Results of AST, ALT, and HbA 1c had significant reductions in each group. For HbA 1c , treatment rate was 71% in the MO group with T2DM with significant reduction of 22.8%. It is thought that a gastric banding surgery is one of the breakthrough methods not only for weight loss but also for the prevention of complication of the obese patients with T2DM. Thus, gastric banding surgery could be effective in controlling HbA 1c in obese patients with type 2 diabetes mellitus.

AIM: To study the preoperative and postoperative role of upper esophagogastroduodenoscopy (EGD) in morbidly obese patients. METHODS: This is a multicenter retrospective study by reviewing the database of patients who underwent bariatric surgery (laparoscopic sleeve gastrectomy, laparoscopic Roux en Y gastric bypass, or laparoscopic minigastric bypass) in the period between 2001 June and 2015 August (Jahra Hospital-Kuwait, Hafr Elbatin Hospital and King Saud Medical City-KSA, and Mansoura University Hospital - Egypt). Patients with age 18-65 years, body mass index (BMI) > 40, or > 35 with comorbidities after failure of many dietetic regimen and acceptable levels of surgical risk were included in the study after having an informed signed consent. We retrospectively reviewed the medical charts of all morbidly obese patients. The patients’ preoperative data included clinical history including upper digestive symptoms and preoperative full workup including EGD. Only patients whose charts revealed weather they were symptomatic or not were studied. We categorized patients accordingly into two groups; with (group A) or without (group B) upper digestive symptoms. The endoscopic findings were categorized into 4 groups based on predetermined criteria. The medical record of patients who developed stricture, leak or bleeding after bariatric surgery was reviewed. Logestic regression analysis was used to identify preoperative predictors that might be associated with abnormal endoscopic findings. RESULTS: Three thousand, two hundred and nineteen patients in the study period underwent bariatric surgery (75% LSG, 10% LRYDB, and 15% MGB). Mean BMI was 43 ± 13, mean age 37 ± 9 years, 79% were female. Twenty eight percent had presented with upper digestive symptoms (group A). EGD was considered normal in 2414 (75%) patients (9% group A vs 66% group B, P = 0.001). The abnormal endoscopic findings were found high in those patients with upper digestive symptoms. Abnormal findings (one or more) were found in 805 (25%) patients (19% group A vs 6% group B, P = 0.001). Seven patients had critical events during conscious sedation due to severe hypoxemia (< 60%). Rate of stricture in our study was 2.6%. Success rate of endoscopic dilation was 100%. One point nine percent patients with gastric leak were identified with 75% success rate of endoscopic therapy. Three point seven percent patients developed acute upper bleeding. Seventy-eight point two percent patients were treated by conservative therapy and EGD was performed in 21.8% with 100% success and 0% complications. CONCLUSION: Our results support the performance of EGD only in patients with upper gastrointestinal symptoms. Endoscopy also offers safe effective tool for anastomotic complications after bariatric surgery. PMID:27247708

Helicobacter pylori ( Hp ) is the primary cause of gastric cancer but we know little of its relative abundance and other microbes in the stomach, especially at the time of gastric cancer diagnosis. Here we characterized the taxonomic and derived functional profiles of gastric microbiota in two different sets of gastric cancer patients, and compared them with microbial profiles in other body sites. Paired non-malignant and tumor tissues were sampled from 160 gastric cancer patients with 80 from China and 80 from Mexico. The 16S rRNA gene V3-V4 region was sequenced using MiSeq platform for taxonomic profiles. PICRUSt was used to predict functional profiles. Human Microbiome Project was used for comparison. We showed that Hp is the most abundant member of gastric microbiota in both Chinese and Mexican samples (51 and 24%, respectively), followed by oral-associated bacteria. Taxonomic (phylum-level) profiles of stomach microbiota resembled oral microbiota, especially when the Helicobacter reads were removed. The functional profiles of stomach microbiota, however, were distinct from those found in other body sites and had higher inter-subject dissimilarity. Gastric microbiota composition did not differ by Hp colonization status or stomach anatomic sites, but did differ between paired non-malignant and tumor tissues in either Chinese or Mexican samples. Our study showed that Hp is the dominant member of the non-malignant gastric tissue microbiota in many gastric cancer patients. Our results provide insights on the gastric microbiota composition and function in gastric cancer patients, which may have important clinical implications.

When performing a laparoscopic assisted gastrectomy, a function-preserving gastrectomy is performed depending on the location of the primary gastric cancer. This study examined the incidence of lymph node metastasis by the lymph node station number by tumor location to determine the optimal extent of the lymph node dissection. The subjects consisted of 1,510 patients diagnosed with gastric cancer who underwent a gastrectomy between 1996 and 2005. The patients were divided into three groups: upper, middle and lower third, depending on the location of the primary tumor. The lymph node metastasis patterns were analyzed in the total and early gastric cancer patients. In all patients, lymph node station numbers 1, 2, 3, 7, 10 and 11 metastases were dominant in the cancer originating in the upper third, whereas station numbers 4, 5, 6 and 8 were dominant in the lower third. In early gastric cancer patients, the station number of lymph nodes with a metastasis did not show a significant difference in stage pT1a disease. On the other hand, a metastasis in lymph node station number 6 was dominant in stage pT1b disease that originated in the lower third of the stomach. When performing a laparoscopic-assisted gastrectomy for early gastric cancer, a limited lymphadenectomy is considered adequate during a function-preserving gastrectomy in mucosal (T1a) cancer. On the other hand, for submucosal (T1b) cancer, a number 6 node dissection should be performed when performing a pylorus preserving gastrectomy.

Gastric cancer remains the second leading cause of cancer death worldwide. About half of the incidence of gastric cancer is observed in East Asian countries, which show a higher mortality than other countries. The effectiveness of 3 new gastric cancer screening techniques, namely, upper gastrointestinal endoscopy, serological testing, and “screen and treat” method were extensively reviewed. Moreover, the phases of development for cancer screening were analyzed on the basis of the biomarker development road map. Several observational studies have reported the effectiveness of endoscopic screening in reducing mortality from gastric cancer. On the other hand, serologic testing has mainly been used for targeting the high-risk group for gastric cancer. To date, the effectiveness of new techniques for gastric cancer screening has remained limited. However, endoscopic screening is presently in the last trial phase of development before their introduction to population-based screening. To effectively introduce new techniques for gastric cancer screening in a community, incidence and mortality reduction from gastric cancer must be initially and thoroughly evaluated by conducting reliable studies. In addition to effectiveness evaluation, the balance of benefits and harms must be carefully assessed before introducing these new techniques for population-based screening. PMID:25320514

A 51-year-old postmenopausal woman was diagnosed as having adenocarcinoma (gastric cancer type 4) from gastric biopsy by upper endoscopy. Her chief complaint was abdominal dilatation. Meanwhile, a breast CT suggested tumor in her left breast and was diagnosed as an invasive lobular carcinoma based on a core needle biopsy. After gastric biopsy, tissues are stained by ER and PgR in immunohistochemistry. The diagnosis was modified from gastric cancer to T2N1M1, stage IV left breast cancer, accompanied by a treatment. Chemotherapy with EC 6 course consisted of a weekly PTX 4 course (epirubicin, cyclophosphamide-weekly paclitaxel) was performed. After the chemotherapy, breast mass, ascites and tumor marker were dramatically improved. Then hormonal therapy was administered. She passed away 2 and 1/2 years after her first visit to the hospital. Metastatic gastric tumors simulating type 4 advanced gastric cancer (MGTS type 4) and invasive lobular carcinoma are known to have an unfavorable prognosis. There is no doubt, however, that the multidisciplinary treatments have brought a satisfaction to her and family. We should keep in mind a possibility of gastric metastasis of breast cancer, when consulting a female patient with gastric cancer type 4.

A 39-year-old woman visited our hospital because of epigastric pain. Gastrointestinal endoscopy revealed a gastric submucosal tumor, 30mm in size, with ulcer locating near to the esophagogastric junction, and it was diagnosed with GIST by the endoscopic ultrasonography-guided fine needle aspiration. Then, she underwent laparoscopic surgery for the removal of gastric GIST. After peeling around the upper stomach, the local resection of the stomach was performed with linear staplers in the minor axis direction under the vision of the endoscope and laparoscope. Histopathological examinations confirmed that the tumor was GIST with an intermediate risk, and all surgical margins were free of GIST cells. Local resection with the laparoscopy endoscopy cooperative surgery(LECS)technique is a very useful way of the removal of gastric GISTs locating near to the esophagogastric junction in terms of the remnant gastric functions. Meanwhile, because the standard LECS requires the opening of the gastric lumen, there remains concerns about the intraperitoneal tumor dissemination for the gastric GIST with ulcer. We herein reported a case of laparoscopic local resection for a gastric GIST with ulcer locating near to the esophagogastric junction without gastric opening.

Gastric air contrast: useful adjunct to hepatic artery scintigraphy

Wahl, R.L.; Ziessman, H.A.; Juni, J.

The utility of scintigraphic views obtained after administration of sodium bicarbonate-citric acid-simethicone crystals (E-Z-GAS) for the determination of gastric extrahepatic perfusion was evaluated in 20 technetium-99m macroaggregated albumin hepatic arterial perfusion studies performed in 19 patients. These crystals produce carbon dioxide gas, distend the stomach, and allow better delineation of gastric activity (extrahepatic perfusion to the stomach). Conversely, a lack of change in activity in the left upper quadrant after the effervescent crystals have been ingested suggests no gastric activity (and no extrahepatic perfusion to the stomach). These air-contrast views added useful information in 16 of 20 studies. Air contrastmore » views of the stomach can be extremely helpful in verifying or excluding the diagnosis of gastric extrahepatic perfusion on technetium-99m macroaggregated albumin hepatic arterial perfusion studies.« less

The aims of this study were to describe the histology in gastroparesis, specifically to relate histopathology to etiology of gastroparesis (idiopathic and diabetic gastroparesis), gastric emptying, and clinical response to gastric electric stimulation. Full thickness gastric body sections obtained during insertion of gastric stimulator in gastroparetics were stained with Hematoxylin & Eosin, Masson Trichrome and immunohistochemical stains for Neuron-Specific Enolase and c-Kit. In all, 145 gastroparetics (71 diabetics, 71 idiopathic, 2 post-surgical, and 1 chronic intestinal pseudo-obstruction) had full thickness gastric body biopsies. A lymphocytic infiltrate was seen in the intermyenteric plexus in 22 diabetic and 23 idiopathic gastroparesis patients. Fibrosis was present in the inner circular layer in 13 diabetic and 15 idiopathics and in the outer longitudinal layer in 46 diabetic and 51 idiopathics. Diabetic gastroparesis had less ganglion cells (3.27±1.82 vs 4.81±2.81/hpf; P<.01) and less ganglia (0.90±0.44 vs 1.10±0.50/hpf; P=.01) than idiopathic gastroparesis. Interstitial cells of Cajal (ICC) count was slightly lower in the inner circular layer in diabetic than idiopathics (2.77±1.47 vs 3.18±1.34/hpf; P=.08). Delayed gastric emptying was associated with reduced ICCs in the myenteric plexus. Global therapeutic response to gastric electric stimulation was inversely related to ganglia/hpf (R=-.22; P=.008). In diabetics, improvements in nausea, vomiting, and abdominal pain were inversely related to fibrosis. Histologic assessment of full thickness gastric biopsy specimens allows correlation of histopathology to the gastroparesis disease process, its etiology, gastric emptying, and response to gastric electric stimulation treatment. © 2017 John Wiley & Sons Ltd.

The adipokine plasminogen activator inhibitor (PAI)-1 is increased in plasma of obese individuals and exhibits increased expression in the stomachs of individuals infected with Helicobacter. To investigate the relevance of gastric PAI-1, we used 1.1 kb of the H+/K+β subunit promoter to overexpress PAI-1 specifically in mouse gastric parietal cells (PAI-1-H/Kβ mice). We studied the physiological, biochemical, and behavioral characteristics of these and mice null for PAI-1 or a putative receptor, urokinase plasminogen activator receptor (uPAR). PAI-1-H/Kβ mice had increased plasma concentrations of PAI-1 and increased body mass, adiposity, and hyperphagia compared with wild-type mice. In the latter, food intake was inhibited by cholecystokinin (CCK)8s, but PAI-1-H/Kβ mice were insensitive to the satiating effects of CCK8s. PAI-1-H/Kβ mice also had significantly reduced expression of c-fos in the nucleus tractus solitarius in response to CCK8s and refeeding compared with wild-type mice. Exogenous PAI-1 reversed the effects of CCK8s on food intake and c-fos levels in the nucleus tractus solitarius of wild-type mice, but not uPAR-null mice. Infection of C57BL/6 mice with Helicobacter felis increased gastric abundance of PAI-1 and reduced the satiating effects of CCK8s, whereas the response to CCK8s was maintained in infected PAI-1–null mice. In cultured vagal afferent neurons, PAI-1 inhibited stimulation of neuropeptide Y type 2 receptor (Y2R) expression by CCK8s. Thus, gastric expression of PAI-1 is associated with hyperphagia, moderate obesity, and resistance to the satiating effects of CCK indicating a new role in suppressing signals from the upper gut that inhibit food intake.

Theory of gastric CO2 ventilation and its control during respiratory acidosis: implications for central chemosensitivity, pH regulation, and diseases causing chronic CO2 retention.

PubMed

Dean, Jay B

2011-02-15

The theory of gastric CO(2) ventilation describes a previously unrecognized reflex mechanism controlled by neurons in the caudal solitary complex (cSC) for non-alveolar elimination of systemic CO(2) during respiratory acidosis. Neurons in the cSC, which is a site of CO(2) chemosensitivity for cardiorespiratory control, also control various gastroesophageal reflexes that remove CO(2) from blood. CO(2) is consumed in the production of gastric acid and bicarbonate in the gastric epithelium and then reconstituted as CO(2) in the stomach lumen from the reaction between H(+) and HCO(3)(-). Respiratory acidosis and gastric CO(2) distension induce cSC/vagovagal mediated transient relaxations of the lower esophageal sphincter to vent gastric CO(2) upwards by bulk flow along an abdominal-to-esophageal (=intrapleural) pressure gradient the magnitude of which increases during abdominal (gastric) compression caused by increased contractions of respiratory muscles. Esophageal distension induces cSC/nucleus ambiguus/vagovagal reflex relaxation of the upper esophageal sphincter and CO(2) is vented into the pharynx and mixed with pulmonary gas during expiration or, alternatively, during eructation. It is proposed that gastric CO(2) ventilation provides explanations for (1) the postprandial increase in expired CO(2) and (2) the negative P(blood - expired)CO₂difference that occurs with increased inspired CO(2). Furthermore, it is postulated that gastric CO(2) ventilation and alveolar CO(2) ventilation are coordinated under dual control by CO(2) chemosensitive neurons in the cSC. This new theory, therefore, presupposes a level of neural control and coordination between two previously presumed dissimilar organ systems and supports the notion that different sites of CO(2) chemosensitivity address different aspects of whole body pH regulation. Consequently, not all sites of central chemosensitivity are equal regarding the mechanism(s) activated for CO(2) elimination. A distributed CO(2) chemosensitive network-at least nine different areas in the CNS, including the cSC, have been reported to date-may reflect the complexity and dynamic nature of the fundamental neural circuitry required to achieve CO(2)/pH regulation across multiple organ systems under various states of arousal, oxygenation, pH status, and redox state. Moreover, coordination of respiratory and digestive control networks through the cSC could also account for the frequent co-expression of pulmonary diseases that cause chronic respiratory acidosis (and overstimulation of cSC neurons) with peptic ulcer disease or gastroesophageal reflux disease.

Beeskow, Anne Bettina; Meyer, Hans-Jonas; Schierle, Katrin; Surov, Alexey

2018-01-01

Abstract Background: Heterotopic gastric tissue can be found in the entire gastrointestinal tract. It is usually located in the upper intestine. Rarely, it can be found in the gallbladder. This study describes several clinically, imaging features as well as histopathology findings of heterotopic gastric tissue in gallbladder (HGM). Methods: The radiologic database of 1 tertiary university hospital was retrospectively screened for HGM. Additionally, a systemic review of the Medline database was conducted to identify previously published cases reports. In all cases clinical, imaging as well as histopathology features were retrieved from the papers. Results: In our databases, 1 patient with HGM was identified. Additionally, the systemic review yielded 32 suitable papers with 34 patients. Clinically, most of the patients suffered from abdominal discomfort. Most of the lesions were located in the lower gallbladder, especially (n = 14, 40%) in the gallbladder neck. On sonography, in 20.7% a broad-based mass was described. In 10.3% a sessile polyp was identified. In 5 cases, the mass was characterized as hyperechoic (55.5%), as isoechoic in 3 (33.3%) cases, and hypoechoic in 1 (11.1%). On computed tomography (CT), the lesions were most frequently hyperdense and all of them showed a slightly enhancement after application of contrast medium. On histopathology, most cases revealed heterotopic gastric mucosa of body-fundic type (60%) with chief and parietal cells, followed by pyloric type glands (20%). Every patient was treated with cholecystectomy and all had an uneventful recovery. Conclusion: HGM is a rare disorder with several differential diagnoses. Typically features were described to identify HGM in clinical routine and rule out malignant diseases like gallbladder carcinoma. PMID:29517663

A rapid image-guided Raman endoscopy system integrated with on-line diagnostic scheme is developed for in vivo Raman tissue diagnosis (optical biopsy) in the upper GI during clinical gastrointestinal endoscopy under multimodal wide-field imaging guidance. The real-time Raman endoscopy technique was tested prospectively on new gastric patients (n=4) and could identify dysplasia in vivo with sensitivity of 81.5% (22/27) and specificity of 87.9% (29/33). This study realizes for the first time the novel image-guided Raman endoscopy as a screening tool for real-time, online diagnosis of gastric cancer and precancer in vivo at endoscopy.

Prevalence of upper gastrointestinal symptoms and their influence on nutritional state and performance status in patients with different primary tumors receiving palliative care.

The aim of this study was to investigate the relationship between gastrointestinal symptoms, nutritional balance, and performance status in patients receiving palliative care for advanced cancers originating in different sites. We studied a total of 105 patients. Upper gastrointestinal symptoms, Eastern Cooperative Oncology Group Performance Status score (ECOG-PS), dietary intakes, anthropometric measures, and some serum proteins were determined. Unintentional weight loss, alterations in anthropometric measures, and highest number of symptoms were greater in patients with lung and stomach cancer. No differences were found in ECOG-PS according to cancer site. Patients with gastric or lung cancer have most evidence of protein-calorie malnutrition and a higher prevalence of upper gastrointestinal symptoms. The performance status is not affected by tumor site. Early nutritional support should be planned for all patients with cancer, especially for patients with gastric or lung cancer.

Aim: The objective of the study was to obtain and compare the two-dimensional (2D) and three-dimensional (3D) ultrasonographic images of pathological conditions of the stomach in dogs in clinical cases. Materials and Methods: In our study, 12 clinical conditions of the stomach were recorded using ultrasonography. The ultrasound machine used for this study was 3D ultrasound machine (Nemio-XG: Toshiba, Japan) having four-dimensional volumetric transducer. Results: Present study was done to compare 2D and 3D ultrasonographic images in different gastric affections in dogs. In case of uremic gastropathy due to inflammatory response, the wall of the stomach was 0.6 cm thick and hyperechoic and gastric folds were also hyperechoic indicative of gastritis. In second, third, and fourth case of gastritis the wall of the stomach was 0.7, 0.6, and 0.55 cm, respectively thick and hyperechoic. In fifth and sixth case of gastritis, inflammatory response due to ingestion of polythene and sand led to gastritis and ultrasonographically, the wall of the stomach was 0.6 cm and 0.7 cm thick, respectively, and hyperechoic. In case of gastric ulcer, ultrasonographically, there was a disruption of gastric mucosal layer. In cases of gastric dilatation, anechoic content indicating fluid was seen in stomach area and due to dilatation boundary of the stomach was not clear and the increase in the lumen of the stomach was observed. In case of foreign body, ultrasonographically the wall of the stomach was 0.55 cm thick and hyperechoic. In the middle of the stomach, multiple hyperechoic shadows of the foreign bodies i.e. leather and bunch of straw of grass were observed. In case of pyloric stenosis ultrasonographically, anechoic lumen of the pylorus surrounded by 0.5 cm hypoechoic thickened muscle. In some cases, 3D ultrasonography was not diagnostic i.e. gastric foreign bodies and gastric dilatation. These conditions were better visualized on the 2D sonogram. Conclusion: The appearance of clinical conditions of the stomach such as gastritis and pyloric stenosis were more distinct on 3D ultrasonogram than 2D ultrasonogram. The 3D ultrasonography was not diagnostic in cases of gastric foreign bodies and gastric dilatation. PMID:27065634

The effects of prolonged administration of genistein, a tyrosine-kinase inhibitor, on sodium-chloride-enhanced induction of gastric carcinogenesis induced by N-methyl-N'-nitro-N-nitrosoguanidine, and the labeling and apoptotic indices and vessel counts in the gastric mucosa and gastric cancers, were investigated in Wistar rats. After 25 weeks of the carcinogen treatment, rats were fed chow pellets containing 10% sodium chloride and were given s.c. injections of genistein at dosages of 15 mg/kg or 30 mg/kg body weight every other day. In week 52, the incidence of gastric cancers was significantly greater in rats fed sodium chloride than in untreated control rats. Prolonged administration of genistein at a dosage of 30 mg/kg, but not 15 mg/kg, body weight significantly reduced the incidence of gastric cancers, which was increased by oral treatment with sodium chloride. Genistein at the higher dose significantly decreased the labeling index and vessel counts of the antral mucosa and the gastric cancers (which were increased by treatment with sodium chloride) and significantly increased the apoptotic index of the antral mucosa and the cancers (which was lowered by the treatment with sodium chloride). These findings suggest that genistein attenuates gastric carcinogenesis promoted by sodium chloride, by inducing increased apoptosis and lower cell proliferation and angiogenesis of antral mucosa and gastric cancers.

To investigate the nutritional status, and provide evidence for nutritional treatment option. A total of 452 patients with gastrointestinal cancer were selected, including 156 gastric cancer,117 colon cancer, and 180 rectal cancer. The nutritional risk screening 2002(NRS2002) was applied to grade the nutritional risk. A multi-frequency bioelectrical impedance analysis was used to measure the patients' body composition. Albumin (Alb), prealbumin(PA), transferring(Tf), retinol binding protein(RBP), red blood cell(RBC), hemoglobin (Hb), haematocrit(Hct) were measured after fasting. The rate of patients with NRS2002 score more than 3 was 70.5%(110/156) for gastric cancer, 53.8%(63/117) for colon cancer, and 46.7%(86/180) for rectal cancer. The score for impaired nutritional status more than 1 for gastric cancer was higher than that for colorectal cancer(P<0.05), while patients with disease score more than 2 was less for gastric cancer(P<0.05). Body mass index(BMI), obesity degree, fat content, fat percentage, and arm circumference were lower in gastric cancer patients as compared to colorectal cancer patients(P<0.05); but protein percentage, muscle percentage, ratio of muscles of arm, and cell mass percentage were higher in gastric cancer patients(P<0.05). The proportions of patients with low Alb, PA, Tf, BC, Hb, Hct were higher for gastric cancer and colon cancer(P<0.05). Patients with gastric cancer are prone to fat loss and therefore have a higher nutritional risk and malnutrition than those with colorectal cancer. Combination of body composition analysis and laboratory examination may achieve comprehensive evaluation of the nutritional status of patients, and provide the evidence of nutritional therapy by being combined with NRS2002 score.

Postnatally diagnosed congenital diaphragmatic hernias (CDH) are rare and have a better prognosis than those diagnosed prenatally. Postnatal symptoms can be respiratory, digestive, or mixed. Gastric volvulus can reveal CDH. Symptoms are pain, abdominal distension, and/or vomiting. Upper gastrointestinal barium X-ray radiography provides the diagnosis. Prognosis is related to early surgical management in complicated forms with intestinal occlusion or sub-occlusion. We report on an infant who presented with vomiting, which revealed gastric volvulus associated with a CDH. Progression was favorable after surgical treatment. Copyright © 2017 Elsevier Masson SAS.

ABSTRACT Purpose Diaphragm and abdominal muscles are susceptible to contractile fatigue in response to high-intensity, whole-body exercise. This study assessed whether the ventilatory and mechanical loads imposed by high-intensity, upper-body exercise would be sufficient to elicit respiratory muscle fatigue. Methods Seven healthy men (mean ± SD; age = 24 ± 4 yr, peak O2 uptake [V˙O2peak] = 31.9 ± 5.3 mL·kg−1·min−1) performed asynchronous arm-crank exercise to exhaustion at work rates equivalent to 30% (heavy) and 60% (severe) of the difference between gas exchange threshold and V˙O2peak. Contractile fatigue of the diaphragm and abdominal muscles was assessed by measuring pre- to postexercise changes in potentiated transdiaphragmatic and gastric twitch pressures (Pdi,tw and Pga,tw) evoked by supramaximal magnetic stimulation of the cervical and thoracic nerves, respectively. Results Exercise time was 24.5 ± 5.8 min for heavy exercise and 9.8 ± 1.8 min for severe exercise. Ventilation over the final minute of heavy exercise was 73 ± 20 L·min−1 (39% ± 11% maximum voluntary ventilation) and 99 ± 19 L·min−1 (53% ± 11% maximum voluntary ventilation) for severe exercise. Mean Pdi,tw did not differ pre- to postexercise at either intensity (P > 0.05). Immediately (5–15 min) after severe exercise, mean Pga,tw was significantly lower than pre-exercise values (41 ± 13 vs 53 ± 15 cm H2O, P < 0.05), with the difference no longer significant after 25–35 min. Abdominal muscle fatigue (defined as ≥15% reduction in Pga,tw) occurred in 1/7 subjects after heavy exercise and 5/7 subjects after severe exercise. Conclusions High-intensity, upper-body exercise elicits significant abdominal, but not diaphragm, muscle fatigue in healthy men. The increased magnitude and prevalence of fatigue during severe-intensity exercise is likely due to additional (nonrespiratory) loading of the thorax. PMID:28288012

Peptide YY (PYY) levels are reported to be decreased in obesity. The relation between gastric functions, satiation, and gut hormones in obesity is incompletely understood. The aim of this study was to compare gastric volumes, emptying, maximum tolerated volumes, postchallenge symptoms, and selected gut hormones in normal, overweight, or obese healthy volunteers. In 73 nonbulimic normal, overweight, or obese participants weighing less than 137 kg, we measured gastric emptying of solids and liquids by scintigraphy (gastric emptying half-time [GE t(1/2)]); gastric volumes by single-photon emission computed tomography; maximum tolerated volumes and symptoms by satiation test; and plasma leptin, ghrelin, insulin, glucagon-like peptide 1, and PYY levels. Groups were compared using 1-way analysis of covariance adjusted for sex. Univariate associations among measured responses were assessed using Spearman correlations. Multiple linear regression models, adjusting for weight and sex, assessed the independent ability of gastric functions and hormones to predict satiation volume. Obese and overweight subjects had significantly lower postprandial gastric volumes, higher fasting and postprandial insulin and leptin levels, and lower fasting ghrelin and lower postprandial reduction in ghrelin levels. PYY levels were not different in obese or overweight subjects compared with controls. The GE t(1/2) was correlated inversely with postprandial PYY; increased body weight was associated with faster GE t(1/2) of solids (r(s) = 0.33, P = .005) and liquids (r(s) = 0.24, P = .04). Postprandial changes in gastric volume and PYY were independent predictors of satiation (both P = .01). Overweight or obesity are associated with lower postprandial gastric volumes and normal PYY levels. Gastric emptying influences postprandial PYY levels. Postprandial PYY and gastric volume independently predict satiation volume in nonbulimic people across a wide body mass index range.

The study aimed to evaluate whether ranitidine and pantoprazole are able to maintain gastric pH >or=4 in septic patients. Twenty intensive care unit patients from a university teaching hospital with sepsis were included in this study. Ten patients received ranitidine (50 mg as an intermittent bolus 3 times a day) and 10 received pantoprazole (40 mg as an intermittent bolus twice a day). Gastric pH was measured continuously for 48 hours. Endoscopy of the upper digestive tract, gastric biopsy, and investigation for Helicobacter pylori were carried out before and at the end of the study. pH values >or=4 were maintained for 46.27% +/- 38.21% and 81.57% +/- 19.65% of study time in the ranitidine and pantoprazole groups, respectively (P = .04). Intravenous ranitidine was unable to maintain gastric pH above 4 in septic patients. All cases in the ranitidine group in whom pH remained above 4 had gastric hypotrophy or atrophy. Pantoprazole successfully maintained pH levels above 4.

Staple line and anastomotic leakages are life-threatening complications after bariatric surgery. Upper gastrointestinal (GI) tract X-ray examination with oral administration of a water-soluble contrast agent can be used to detect leaks. The aim of this study was to evaluate the impact of routine upper GI tract fluoroscopy after primary bariatric surgery. Between January 2009 and December 2014 a total of 658 bariatric interventions were carried out of which 442 were primary bariatric operations. Included in this single center study were 307 sleeve gastrectomies and 135 Roux-en-Y gastric bypasses. Up to December 2012 upper GI tract fluoroscopy was performed routinely between the first and third postoperative days and the detection of leakages was evaluated. In the investigation period 8 leakages (2.6 %) after sleeve gastrectomy, 1 anastomotic leakage in gastrojejunostomy and 1 in jejunojejunostomy after Roux-en-Y gastric bypass occurred. All patients developed clinical symptoms, such as abdominal pain, tachycardia or fever. In one case the leakage was detected by upper GI fluoroscopy and in nine cases radiological findings were unremarkable. No leakages were detected in asymptomatic patients. Routine upper GI fluoroscopy is not recommended for uneventful postoperative courses after primary bariatric surgery.

Medical and Endoscopic Management of Gastric Varices

In the past 20 years, our understanding of the pathophysiology and management options among patients with gastric varices (GV) has changed significantly. GV are the most common cause of upper gastrointestinal bleeding in patients with portal hypertension after esophageal varices (EV) and generally have more severe bleeding than EV. In the United States, the majority of GV patients have underlying portal hypertension rather than splenic vein thrombosis. The widely used classifications are the Sarin Endoscopic Classification and the Japanese Vascular Classifications. The former is based on the endoscopic appearance and location of the varices, while the Japanese classification is based on the underlying vascular anatomy. In this article, the authors address the current concepts of classification, epidemiology, pathophysiology, and emerging management options of gastric varices. They describe the stepwise approach to patients with gastric varices, including the different available modalities, and the pearls, pitfalls, and stop-gap measures useful in managing patients with gastric variceal bleed.

Helicobacter pylori Infection, Chronic Inflammation, and Genomic Transformations in Gastric MALT Lymphoma

PubMed Central

Witkowska, Magdalena; Smolewski, Piotr

2013-01-01

Nowadays, it is believed that the main role in the development of gastric mucosa-associated lymphoid tissue (MALT) lymphoma plays Helicobacter pylori infection. This world-wide distributed bacteria is in charge of most cases of not only upper gastrointestinal tract disorders but also some of extragastric problems. Constant stimulation of the immune system causes a B-lymphocytes proliferation, which is considered to be responsible for the neoplastic transformation. On the other hand, there are 10%–20% of patients who do not respond to Helicobacter pylori eradication treatment. This group has often a chromosome translocation, which suggests that there is another unknown, so far, pathogenetic mechanism of MALT lymphoma. Majority of genetic abnormalities are connected with nuclear factor-κB (NF-κB) pathway, which activates the uncontrolled proliferation of neoplastic cells. Translocations already described in studies are t(11;18)(q21;q21), which is the most common, t(14;18)(q32;q21), t(14;18)(q32;q21), and t(3;14)(p14.1;q32). This non-Hodgkin's lymphoma is an indolent type originated outside lymph nodes. In more than 50% of cases, it occurs in the stomach. Occasionally, it can be found in salivary and thyroid gland, lung, breast, bladder, skin, or any other place in the human body. This paper is a review of the current knowledge on etiology, pathogenesis, treatment, and follow-up of gastric MALT lymphoma. PMID:23606792

γ-aminobutyric acid (GABA) receptors, responding to GABA positive allosteric modulators, are present in the freshwater polyp Hydra vulgaris (Cnidaria, Hydrozoa), one of the most primitive metazoans to develop a nervous system. We examined the occurrence and distribution of GABA A receptor subunits in Hydra tissues by western blot and immunohistochemistry. Antibodies against different GABA A receptor subunits were used in Hydra membrane preparations. Unique protein bands, inhibited by the specific peptide, appeared at 35, 60, ∼50 and ∼52 kDa in membranes incubated with α3, β1, γ3 or δ antibodies, respectively. Immunohistochemical screening of whole mount Hydra preparations revealed diffuse immunoreactivity to α3, β1 or γ3 antibodies in tentacles, hypostome, and upper part of the gastric region; immunoreactive fibers were also present in the lower peduncle. By contrast, δ antibodies revealed a strong labeling in the lower gastric region and peduncle, as well as in tentacles. Double labeling showed colocalization of α3/β1, α3/γ3 and α3/δ immunoreactivity in granules or cells in tentacles and gastric region. In the peduncle, colocalization of both α3/β1 and α3/γ3 immunoreactivity was found in fibers running horizontally above the foot. These data indicate that specific GABA A receptor subunits are present and differentially distributed in Hydra body regions. Subunit colocalization suggests that Hydra GABA receptors are heterologous multimers, possibly sub-serving different physiological activities.

AIM: To investigate the prevalence and risk factors of asymptomatic peptic ulcer disease (PUD) in a general Taiwanese population. METHODS: From January to August 2008, consecutive asymptomatic subjects undergoing a routine health check-up were evaluated by upper gastrointestinal endoscopy. Gastroduodenal mucosal breaks were carefully assessed, and a complete medical history and demographic data were obtained from each patient. Logistic regression analysis was conducted to identify independent risk factors for asymptomatic PUD. RESULTS: Of the 572 asymptomatic subjects, 54 (9.4%) were diagnosed as having PUD. The prevalence of gastric ulcer, duodenal ulcer and both gastric and duodenal ulcers were 4.7%, 3.9%, and 0.9%, respectively. Multivariate analysis revealed that prior history of PUD [odds ratio (OR), 2.0, 95% CI: 1.3-2.9], high body mass index [body mass index (BMI) 25-30: OR, 1.5, 95% CI: 1.0-2.2; BMI > 30 kg/m2: OR, 3.6, 95% CI: 1.5-8.7] and current smoker (OR, 2.6, 95% CI: 1.6-4.4) were independent predictors of asymptomatic PUD. In contrast, high education level was a negative predictor of PUD (years of education 10-12: OR, 0.5, 95% CI: 0.3-0.8; years of education > 12: OR, 0.6, 95% CI: 0.3-0.9). CONCLUSION: The prevalence of PUD in asymptomatic subjects is 9.4% in Taiwan. Prior history of PUD, low education level, a high BMI and current smoker are independent risk factors for developing asymptomatic PUD. PMID:21448426

Solubility of indium-tin oxide in simulated lung and gastric fluids: Pathways for human intake.

2017-02-01

From being a metal with very limited natural distribution, indium (In) has recently become disseminated throughout the human society. Little is known of how In compounds behave in the natural environment, but recent medical studies link exposure to In compounds to elevated risk of respiratory disorders. Animal tests suggest that exposure may lead to more widespread damage in the body, notably the liver, kidneys and spleen. In this paper, we investigate the solubility of the most widely used In compound, indium-tin oxide (ITO) in simulated lung and gastric fluids in order to better understand the potential pathways for metals to be introduced into the bloodstream. Our results show significant potential for release of In and tin (Sn) in the deep parts of the lungs (artificial lysosomal fluid) and digestive tract, while the solubility in the upper parts of the lungs (the respiratory tract or tracheobronchial tree) is very low. Our study confirms that ITO is likely to remain as solid particles in the upper parts of the lungs, but that particles are likely to slowly dissolve in the deep lungs. Considering the prolonged residence time of inhaled particles in the deep lung, this environment is likely to provide the major route for uptake of In and Sn from inhaled ITO nano- and microparticles. Although dissolution through digestion may also lead to some uptake, the much shorter residence time is likely to lead to much lower risk of uptake. Copyright © 2016 The Authors.

To evaluate potential differences between 2 devices used to perform laparoscopic adjustable gastric bandings (the Swedish adjustable gastric band and the Lap-Band). The following groups were considered eligible: (1) patients with a body mass index (calculated as weight in kilograms divided by height in meters squared) of greater than 40; (2) patients with a body mass index between 35 and 40, with associated comorbidities; and (3) patients with a body mass index of greater than 60 who could not undergo derivative procedures. We recruited 400 patients. The mean +/- SD body mass index decreased to 40.6 +/- 3.0 after the first year and to 35.2 +/- 7.0 after 2 years. The average excess weight loss reduction was 48.2% after 1 year and 56.0% after 2 years. The excess weight loss reduction was inversely related to the initial weight: patients with an estimated weight excess of 50 kg or less (108 patients [27.0%]) had an excess weight loss reduction of 55% after 2 years; those with a weight excess of greater than 50 kg (292 patients [73.0%]) had an excess weight loss reduction of 44% (P = .004). We recorded 1 death (0.2%). Transient gastric occlusions (24 patients [6.0%]) and slippages (12 patients [3.0%]) were the most common complications. The devices used (Swedish adjustable gastric band and Lap-Band) were similar in terms of correction of obesity and morbidity. Laparoscopic adjustable gastric banding is a safe and feasible technique with specific indications in moderately obese patients and, secondarily, in highly obese patients who are unfit for more invasive techniques. No differences were found among the devices examined. isrctn.org Identifier: ISRCTN22839090.

Dutch national guidelines on the diagnosis and treatment of gastric cancer recommend the use of perioperative chemotherapy in patients with resectable gastric cancer. However, adjuvant chemotherapy is often not administered. The aim of this study was to evaluate hospital variation on the probability to receive adjuvant chemotherapy and to identify associated factors with special attention to postoperative complications. All patients who received neoadjuvant chemotherapy and underwent an elective surgical resection for stage IB-IVa (M0) gastric adenocarcinoma between 2011 and 2015 were identified from a national database (Dutch Upper GI Cancer Audit). A multivariable linear mixed model was used to evaluate case-mix adjusted hospital variation and to identify factors associated with adjuvant therapy. Of all surgically treated gastric cancer patients who received neoadjuvant chemotherapy (n = 882), 68% received adjuvant chemo(radio)therapy. After adjusting for case-mix and random variation, a large hospital variation in the administration rates for adjuvant was observed (OR range 0.31-7.1). In multivariable analysis, weight loss, a poor health status and failure of neoadjuvant chemotherapy completion were strongly associated with an increased likelihood of adjuvant therapy omission. Patients with severe postoperative complications had a threefold increased likelihood of adjuvant therapy omission (OR 3.07 95% CI 2.04-4.65). Despite national guidelines, considerable hospital variation was observed in the probability of receiving adjuvant chemo(radio)therapy. Postoperative complications were strongly associated with adjuvant chemo(radio)therapy omission, underlining the need to further reduce perioperative morbidity in gastric cancer surgery.

Gastric involvement is unusual in primary mediastinal large B-cell lymphoma (PMLBCL), which has not yet been adequately studied. The aim of this retrospective study was to investigate the frequency of gastric involvement in 204 consecutive patients with PMLBCL that presented at 23 hospitals in Greece. Two out of 204 patients (1.0%) had gastric involvement at presentation. The first patient had symptomatic gastric disease manifested as upper gastrointestinal (GI) hemorrhage, which was the presenting symptom (first case reported in the literature). The second patient underwent positron emission tomography/computed tomography (PET/CT) at baseline staging which revealed abnormal gastric uptake. Histological examination revealed discordant lymphomatous involvement (MALT lymphoma, in a 33-year old female). The estimated frequency of gastric involvement by conventional staging was 1/204 (0.49%), but no cases were identified among asymptomatic patients. Among asymptomatic patients who underwent PET/CT at baseline staging, the PET/CT-based frequency of gastric involvement was 7.1%, but lymphomatous gastric involvement was discordant. Finally, the frequency of gastric involvement in primary progressive or relapsed disease was 2.2%. Our study shows that gastric involvement is uncommon but can be seen in different clinical settings at presentation or at progression/relapse of PMLBCL. PET/CT-based staging may provide more accurate information regarding the true incidence of sub-clinical gastric involvement in this entity, but histological confirmation is essential in order to confirm the diagnosis.

Objective To investigate the protective effect of the combination of turmeric (Curcuma domestica), cardamom pods (Amomum compactum) and sembung leaf (Blumea balsamifera) on gastric mucosa in aspirin-induced gastric ulcer model rats. Methods Thirty male Wistar rats weighing 150-200 g were divided into 6 groups. Four groups were administered with the hot water extracts combination consisted of cardamom pods 36.6 mg/200 g body weight and sembung leaf 91.5 mg/200 g body weight (fixed doses). The herbal extracts combination were also consisted of turmeric in various doses i.e. 10 mg/200 g body weight in the second group, 30 mg/200 g body weight in the first and third groups, and 50 mg/200 g body weight in the fourth group. The fifth group rats received sucralfate 72 mg /200 g body weight. Ten minutes after receiving herbal extracts combinations or sucralfate, the rats were induced with aspirin 90 mg/200 g body weight except the first group. Another group (sixth group) only received aspirin without any protective agent. All treatments were adsministered orally for seven days. The number and area of the gastric ulcers were counted and measured macroscopically. Score of mucosal damage and the number of eosinophils as well as the number of mast cells were observed in paraffin sections stained with hematoxylin eosin and toluidine blue, respectively. Results The groups receiving herbal infuse combination exhibited less number and smaller area of gastric ulcers as well as smaller score of mucosal damage in comparison to those of aspirin group (P<0.05). The number of mast cells and eosinophil of herbal groups were also smaller than that of aspirin group. Conclusions The herbal extracts combination of turmeric (Curcuma domestica), cardamom pods (Amomum compactum) and sembung leaf (Blumea balsamifera) has potential gastroprotective effects.

Glomus tumour (GT) is a rare mesenchymal tumour of the stomach with Gastrointestinal Stromal Tumour (GIST), leiomyoma and schwannoma being far more common and comprising more than 90% of all gastric mesenchymal tumours. As glomus bodies are located in the peripheral parts of the human body, these tumours are peripherally located, classically the subungual region, hands, feet and trunk. While being evaluated for renal problems, a middle aged lady was incidentally found to have a gastric tumour. This was submucosal in location and was excised by a wedge resection and reported elsewhere as carcinoid tumour. The patient came to our hospital for further management. The biopsy was reviewed here and the modified diagnosis given was GT, confirmed by panel of immunohistochemistry. Two years after regular clinical follow up the patient is free of disease or any distant metastasis. In this paper the authors discuss the potential pitfalls, differential diagnoses and diagnostic clues that help in diagnosing this gastric tumour.

Helicobacter pylori (H. pylori) infection and eradication therapy have been known to influence gastric ghrelin and leptin secretion, which may lead to weight gain. However, the exact relationship between plasma ghrelin/leptin levels and H. pylori infection has remained controversial. The aim of this study was to investigate plasma ghrelin and leptin levels in H. pylori-positive and -negative patients, to compare the two levels of the hormones before and after H. pylori eradication, and to examine the correlation between body mass index (BMI) and active ghrelin or leptin levels, as well as that between atrophic pattern and active ghrelin or leptin levels. Seventy-two H. pylori-positive patients who underwent upper gastrointestinal endoscopy, 46 diagnosed as having peptic ulcer and 26 as atrophic gastritis, were enrolled. Control samples were obtained from 15 healthy H. pylori-negative volunteers. The extent of atrophic change of the gastric mucosa was assessed endoscopically. Body weight was measured and blood was collected before and 12 weeks after H. pylori eradication therapy. Blood samples were taken between 8 and 10 AM after an overnight fast. Plasma ghrelin levels were significantly lower in H. pylori-positive patients than in H. pylori-negative patients. In particular, plasma active ghrelin levels were significantly lower in patients with gastritis compared with patients with peptic ulcer. Plasma ghrelin levels decreased after H. pylori eradication in both peptic ulcer and gastritis patients, while plasma leptin levels increased only in peptic ulcer patients. Plasma leptin levels and BMI were positively correlated, and active ghrelin levels and atrophic pattern were weakly negatively correlated in peptic ulcer patients. H. pylori infection and eradication therapy may affect circulating ghrelin/leptin levels. This finding suggests a relationship between gastric mucosal injury induced by H. pylori infection and changes in plasma ghrelin and leptin levels.

Air pollution has been classified as carcinogenic to humans. However, to date little is known about the relevance for cancers of the stomach and upper aerodigestive tract (UADT). We investigated the association of long-term exposure to ambient air pollution with incidence of gastric and UADT cancer in 11 European cohorts. Air pollution exposure was assigned by land-use regression models for particulate matter (PM) below 10 µm (PM 10 ), below 2.5 µm (PM 2.5 ), between 2.5 and 10 µm (PM coarse ), PM 2.5 absorbance and nitrogen oxides (NO 2 and NO X ) as well as approximated by traffic indicators. Cox regression models with adjustment for potential confounders were used for cohort-specific analyses. Combined estimates were determined with random effects meta-analyses. During average follow-up of 14.1 years of 305 551 individuals, 744 incident cases of gastric cancer and 933 of UADT cancer occurred. The hazard ratio for an increase of 5 µg/m 3 of PM 2.5 was 1.38 (95%-CI 0.99;1.92) for gastric and 1.05 (95%-CI 0.62;1.77) for UADT cancers. No associations were found for any of the other exposures considered. Adjustment for additional confounders and restriction to study participants with stable addresses did not influence markedly the effect estimate for PM 2.5 and gastric cancer. Higher estimated risks of gastric cancer associated with PM 2.5 was found in men (HR 1.98 (1.30;3.01)) as compared to women (HR 0.85 (0.5;1.45)). This large multicentre cohort study shows an association between long-term exposure to PM 2.5 and gastric cancer, but not UADT cancers, suggesting that air pollution may contribute to gastric cancer risk.

Breast carcinoma metastasis to the gastrointestinal tract is rare and more frequently associated with lobular than ductal carcinoma (Borst and Ingold, Surg 114(4):637-641 [1]). The purpose of this article is to present a case based review of a unique gastrointestinal metastasis and literature review. A 46 year old lady with metastatic invasive ductal breast cancer was admitted to A&E with sudden onset of epigastric and left shoulder pain. She completed the first cycle of capecitabine/vinorelbine 1 week previously. Clinical examination revealed a tender epigastrium with rigidity in the upper abdomen. Free air under the diaphragm and a positive Rigler's sign was radiologically identified. A laparoscopy demonstrated a fibrinous exudate in the left upper quadrant consistent with a walled off lesser curvature gastric perforation. A subsequent oesophagogastroduodenoscopy (OGD) demonstrated a healed gastric ulcer of benign appearance; however the pathology confirmed metastatic breast carcinoma. Literature review confirmed no previously reported cases of vinorelbine induced gastric perforation. Four cases of metastatic breast cancer with gastric metastasis presenting with perforation were identified; three of these cases (Fra et al., Presse Med 25(26):1215 (1996) [2], Solis-Caxaj et al., Gastroenterol Clin Biol 28(1):91-92 (2004) [3], Ghosn et al., Bull Cancer 78(11):1071-1073 (1991) [4]), were in the French medical literature, including one male patient (Fra et al., Presse Med 25(26):1215 (1996) [2]) and at least one ductal breast carcinoma (Solis-Caxaj et al., Gastroenterol Clin Biol 28(1):91-92 (2004) [3]). The fourth case (van Geel et al., Ned Tijdschr Geneeskd 144(37):1761-1763 (2000) [5]), was in the Dutch medical literature and a lobular breast carcinoma. This case represents a rare complication of breast cancer chemotherapy, the subsequent significant benefit the patient received from treatment is consistent with the chemosensitivity to therapy that also resulted in gastric perforation. Five years after gastric perforation she resumed palliative chemotherapy after progression on sequential hormonal therapies.

Delayed gastric emptying (DGE) is a specific, worrisome complication after pancreaticoduodenectomy (PPPD), whereas subtotal stomach-preserving pancreaticoduodenectomy (SSPPD) that excises the pylorus ring seems to be effective in reducing DGE. This study compared gastric emptying and nutritional status between PPPD and SSPPD over 1 year. From June 2003 to December 2007, 41 patients (PPPD: 33, SSPPD: 8) were enrolled in this study to evaluate differences in gastric emptying and nutritional status at 1, 3, 6, 9 and 12 months after pancreaticoduodenectomy. Gastric emptying was evaluated by 13C-acetate breath test. Nutritional status (body weight, serum levels of total protein, albumin and total cholesterol) was similarly assessed. At 1 month, gastric emptying evaluated at T1/2 (half-emptying time) was significantly prolonged in the PPPD but not in the SSPPD compared to the preoperative level. Thereafter, T1/2 was decreased and showed function significantly better preserved at 3, 6 and 12 months after PPPD than after SSPPD. Body weight recovery was significantly better at 6 and 12 months after PPPD than after SSPPD. Other nutritional parameters were better preserved in the PPPD during 1-year follow-up. PPPD seems to be a more suitable surgical procedure than SSPPD in regard to gastric emptying and nutritional status.

Effect of anthocyanins on expression of matrix metalloproteinase-2 in naproxen-induced gastric ulcers.

Non-steroidal anti-inflammatory drugs cause gastric ulceration through a number of mechanisms including inhibition of PG synthesis, generation of reactive oxygen species (ROS) and induction of apoptosis. Recently, matrix metalloproteinases (MMP) have been suggested to play a crucial role in these mechanisms. The present study investigated the protective effect of anthocyanins isolated from black rice bran (Heugjinjubyeo) against naproxen-induced gastric mucosal injury in rats. The oral administration of anthocyanins (5, 25 or 50 mg/kg body weight) showed significant protection against naproxen (80 mg/kg body weight)-induced gastric ulcer and inhibited lipid peroxidation in the gastric mucosa. In addition, pretreatment with anthocyanins resulted in a significant increase in the activities of radical-scavenging enzymes such as superoxide dismutase, catalase and glutathione peroxidase. Also biochemical and zymographic analyses suggested that the administration of anthocyanins gives a significant protection against naproxen-induced gastric antral ulcer through scavenging ROS and regulation of matrix metalloproteinase-2 (MMP-2) activity. The results of intracellular radical activation show that anthocyanins suppress the generation of intracellular ROS and attenuate the suppression of MMP-2 activity by naproxen. These results suggest that anthocyanins extracted from black rice may offer potential remedy of gastric antral ulceration.

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.

In this case report, we describe two patients who showed a diffusely whitish mucosa in the posterior wall and the lesser curvature of the gastric body. The patients were serologically- and histopathologically-negative for Helicobacter pylori. Random biopsy specimens from the stomach revealed no regenerative changes, intestinal metaplasia, and/or foveolar hyperplasia in either of the patients. Although lanthanum deposition in the gastric mucosa has been reported to occur in close association with H. pylori-associated gastritis, our patients tested negative for H. pylori. These cases suggest that lanthanum deposition presents as whitish lesions in the gastric body in H. pylori-negative patients.

We report here the case of a 65-year-old woman who suffered intraperitoneal sclerosant leakage after endoscopic injection sclerotherapy for bleeding gastric varices. In total, 3 ml of N-butyl-2-cyanoacrylate and Lipiodol mixture was injected. The patient developed mild fever and pain over the left upper quadrant and flank after the procedure. In addition to a Lipiodol-filled gastric varix, the imaging studies disclosed a wide spread of Lipiodol over the left peritoneal cavity. The patient was kept fasting with parenteral antibiotics and nutrition. She responded well to the treatment, and all of the symptoms had subsided 6 days later.

Background Recent guidelines from NICE have proposed that open access gastroscopy is largely limited to patients with “alarm” symptoms. Aims and methods This study reviewed the outcome of all our patients with verified oesophageal or gastric carcinoma who presented with uncomplicated dyspepsia to see if endoscopic investigation is warranted in this group. All patients with histologically verified upper gastrointestinal (GI) cancers who presented over a period from 1998 to 2002 were identified. Their presenting symptoms, treatment, and outcome were analysed. Results 228 upper GI cancers (119 oesophageal, 109 gastric; mean age 72 years (29–99 years); 130 male, 82 female) were identified in 11 145 endoscopies performed. Only 14 patients (6.2%) presented without alarm symptoms; three patients were under 55 years of age and all had gastric carcinoma—one of these had chronic diarrhoea only. Eleven had dyspepsia or reflux symptoms only, and two were under surveillance for Barrett's oesophagus. Only five patients had a curative surgical resection and are still alive two—six years from diagnosis. A sixth patient had a curative operation but died of a cerebrovascular accident one year later. The remaining eight patients unfortunately had either metastatic disease or comorbidity, which precluded surgery. All of these died within two years of diagnosis, mean survival 10 months. Conclusion Only five patients with dyspepsia and no alarm symptoms had resectable upper GI malignancies over a four year period. Limiting open access gastroscopy to those with alarm features only would “miss” a small number of patients who have curable upper GI malignancy. PMID:16397081

Background and study aims: Endoscopic submucosal dissection (ESD) using insulation-tipped knives (IT knives) to treat gastric lesions located on the greater curvature of the gastric body remains technically challenging because of the associated bleeding, control of which can be difficult and time consuming. To eliminate these difficulties, we developed a novel strategy which we have called the “near-side approach method” and assessed its utility. Patients and methods: We reviewed patients who underwent ESD for solitary early gastric cancer located on the greater curvature of the gastric body from January 2003 to September 2014. The technical results of ESD were compared between the group treated with the novel near-side approach method and the group treated with the conventional method. Results: This study included 238 patients with 238 lesions, 118 of which were removed using the near-side approach method and 120 of which were removed using the conventional method. The median procedure time was 92 minutes for the near-side approach method and 120 minutes for the conventional method. The procedure time was significantly shorter in the near-side approach method arm. Although, the procedure time required by an experienced endoscopist was not significantly different between the two groups (100 vs. 110 minutes), the near-side approach group showed significantly shorter procedure time for a less-experienced endoscopist (90 vs. 120 minutes). Conclusions: The near-side approach method appears to require less time to complete gastric ESD than the conventional method using IT knives for technically challenging lesions located on the greater curvature of the gastric body, especially if the procedure is performed by less-experienced endoscopists.

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.

The vascularization of a gastric tube as a substitute for the esophagus is affected by its diameter.

The stomach is used for reconstruction of the upper gastrointestinal tract after esophageal resection for cancer. The whole stomach can be used, but also a wide or narrow gastric tube can be constructed. Short-term functional results are superior after use of a narrow tube. Healing of the cervical esophagogastrostomy can be impaired, leading to leakage and stricture. The decreased vascularization at the site of the anastomosis may be one reason. It was hypothesized that the quality of the vascularization of the gastric tube, used as a substitute for the oesophagus after esophagectomy, depends on its diameter. The vascularization of postmortem specimens was studied using angiography. Whole stomachs (3), wide (3) and narrow gastric tubes (3) were constructed. In a patient with an anastomotic stricture of a narrow tube with a cervical esophagogastrostomy vascularisation was evaluated by angiography. After infusion of contrast through the supplying arteries, the whole stomachs and wide gastric tubes showed adequate vascularization, whereas the narrow gastric tube showed poor vascularization especially at the site of the anastomosis. In narrow gastric tubes, the right gastroepiploic artery was the only feeding artery. In the patient's angiography, a limited contrast visualization of the proximal end of the gastric tube could be demonstrated. Although a narrow gastric tube is favoured by some surgeons, the use of whole stomach or a type of gastric tube with preservation of the right gastric artery may lead to a better anastomotic healing.

In the normal acid-secreting stomach, luminally generated nitric oxide, which contributes to carcinogenesis in the proximal stomach, is associated with the concentration of nitrate plus nitrite (nitrate/nitrite) in gastric juice. We investigated whether the serum nitrate/nitrite concentration is associated with that of gastric juice and whether it can be used as a serum marker. Serum and gastric juice nitrate/nitrite concentration, Helicobacter pylori antibody, and gastric pH were measured in 176 patients undergoing upper endoscopy. Multiple regression analysis revealed that serum nitrate/nitrite concentration was the best independent predictor of gastric juice nitrate/nitrite concentration. On single regression analysis, serum and gastric juice nitrate/nitrite concentration were significantly correlated, according to the following equation: gastric juice nitrate/nitrite concentration (μmol/l) = 3.93 - 0.54 × serum nitrate/nitrite concentration (μmol/l; correlation coefficient = 0.429, p < 0.001). In analyses confined to subjects with gastric pH less than 2.0, and in those with serum markers suggesting normal acid secretion (pepsinogen-I >30 ng/ml and negative H. pylori antibody), the serum nitrate/nitrite concentration was an independent predictor of the gastric juice nitrate/nitrite concentration (p < 0.001). Measuring the serum nitrate/nitrite concentration has potential in estimating the gastric juice nitrate/nitrite concentration. The serum nitrate/nitrite concentration could be useful as a marker for mutagenesis in the proximal stomach. Copyright © 2011 S. Karger AG, Basel.

Digestive volvulus affects the stomach, small bowel and mobile segments of the colon and often has a developmental cause. Reference radiologic examinations include upper gastrointestinal contrast series for gastric volvulus, possibly with ultrasonography for small-bowel volvulus, and contrast enema for colonic volvulus. Treatment is usually surgical. This pictorial essay describes the embryological development and discusses the clinical and radiologic presentation of volvulus, depending on location, and details the appropriate radiologic examinations.

Gastric dysrhythmias and the current status of electrogastrography

Myoelectrical activity recorded simultaneously from mucosal, serosal, and cutaneous electrodes has confirmed that the 3-cpm signal from such electrodes reflects gastric slow-wave activity. Now, the observation that patients with unexplained nausea and vomiting may have very rapid slow-wave frequencies (tachygastrias) and very slow, slow-wave frequencies (bradygastrias) suggests that electrogastrography, a reliable and noninvasive technique, may be useful in the diagnosis and management of patients with upper abdominal symptoms and gastroparesis.

In the last three decades, numerous polysaccharides and polysaccharide-protein complexes have been isolated from plant or animal and used as a promising source of therapeutic agents for cancer. In this study, we examined the effects of Purslane polysaccharides (PPs) on the oxidative injury and immune status in N-methyl-N'-nitro-N-nitrosoguanidine (MNNG)-induced gastric cancer rats. PPs administration (200, 400 or 800mg/kg body weight) could not only increase the body weight, peripheral white blood cells (WBC) count, thymus and spleen indexes, but also remarkably promote splenocytes proliferation of gastric cancer rats. Furthermore, the production of serum cytokines in gastric cancer rats, such as interleukin-2 (IL-2), interleukin-4 (IL-4) and tumor necrosis factor-alpha (TNF-α) was enhanced by PPs treatment. Besides, treatment with PPs was found to provide a dose-dependent protection against MNNG-induced oxidative injury by enhancing SOD, CAT, GSH-Px activities of gastric cancer rats. Taken together, we concluded that enhancement of antioxidants and immune response might be responsible for the anticancer effect of PPs in gastric cancer. Copyright © 2014 Elsevier B.V.

Using digital photo technology to improve visualization of gastric lumen CT images

2006-12-01

In order to evaluate the gastric lumen CT images better, a new method is being applied to images using an Image Processing software. During a 12-month period, 69 patients with various gastric symptoms and 20 normal (as far as it concerns the upper gastrointestinal system) volunteers underwent computed tomography of the upper gastrointestinal system. Just before the examination the patients and the normal volunteers underwent preparation with 40 ml soda water and 10 ml gastrografin. All the CT images were digitized with an Olympus 3.2 Mpixel digital camera and further processed with an Image Processing software. The administration per os of gastrografin and soda water resulted in the distension of the stomach and consequently better visualization of all the anatomic parts. By using an Image Processing software in a PC, all the pathological and normal images of the stomach were better diagnostically estimated. We believe that the photo digital technology improves the diagnostic capacity not only of the CT image but also in MRI and probably many other imaging methods.

Development of a gastroretentive pulsatile drug delivery platform.

PubMed

Thitinan, Sumalee; McConville, Jason T

2012-04-01

To develop a novel gastroretentive pulsatile drug delivery platform by combining the advantages of floating dosage forms for the stomach and pulsatile drug delivery systems. A gastric fluid impermeable capsule body was used as a vessel to contain one or more drug layer(s) as well as one or more lag-time controlling layer(s). A controlled amount of air was sealed in the innermost portion of the capsule body to reduce the overall density of the drug delivery platform, enabling gastric floatation. An optimal mass fill inside the gastric fluid impermeable capsule body enabled buoyancy in a vertical orientation to provide a constant surface area for controlled erosion of the lag-time controlling layer. The lag-time controlling layer consisted of a swellable polymer, which rapidly formed a gel to seal the mouth of capsule body and act as a barrier to gastric fluid ingress. By varying the composition of the lag-time controlling layer, it was possible to selectively program the onset of the pulsatile delivery of a drug. This new delivery platform offers a new method of delivery for a variety of suitable drugs targeted in chronopharmaceutical therapy. This strategy could ultimately improve drug efficacy and patient compliance, and reduce harmful side effects by scaling back doses of drug administered. © 2012 The Authors.

We present the case of a 52 years old man, with significant familial history, diagnosed with familial adenomatous polyposis-attenuated form, with no clinical and endoscopic surveillance until 2001 when he was admitted for an upper gastrointestinal haemorrhage episode. Upper gastrointestinal scopy revealed duodenal adenomatous polyps and gastric hyperplastic polyps. The patient underwent duodenopancreatectomy with total gastrectomy. The histopathological exam revealed duodenal G2 adenocarcinoma pT3N0, and gastric hyperplastic polyps with no signs of dysplasia. The surgical procedure was followed by chemotherapy. In 2002 the patient was admitted for rectal bleeding and colonoscopy showed 2 sigmoid polyps, appropriate for endoscopic removal and a poly-lobate polyp in the transverse colon. The patient underwent transverse colectomy (the histopathological exam--in situ carcinoma). March 2003--the patient underwent endoscopic removal for a rectal polyp (histopathological exam: moderate dysplasia). In 2005 was noted a pulmonary nodule, located in the postero-apical segment of upper left lobe, for which left superior lobe resection was performed (the histopathological exam: metastatic adenocarcinoma). In May 2006 was performed an exploratory laparotomy. Intraoperatively were noted: peritoneal carcinomatosis and multiple liver metastasis. The surgical procedure recommended in patients with attenuated form of familial adenomatous polyposis and suspect periampullary lesions is duodenopancreatectomy. The particularity of the case is the association of total gastrectomy for gastric hyperplastic polyps.

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.

Calcium carbasalate is a therapeutically active salicylate which seems to cause less gastroduodenal mucosal damage than aspirin in laboratory animals. This endoscopist-blinded, randomised, cross over trial aimed to compare acute gastric mucosal damage in 20 healthy volunteers treated with acetyl salicylic acid (ASA) (650 mg three times daily) and effervescent calcium carbasalate (ECC) (826.8 mg three times daily) bioequivalent to 650 mg ASA over a five day period. Endoscopy was performed immediately before treatment and on day 5 of each treatment. Serum salicylate, thromboxane B2, and gastric mucosal prostaglandin E2 (PGE2) concentrations were measured after endoscopy. ECC caused fewer gastric mucosal erosions than ASA. The total number of gastric erosions was 23.8 (16.1) in the ASA treated subjects compared with 9.1 (8.7) in ECC treated subjects (p = 0.004). Differences between ASA and ECC were significant for both the gastric antrum and body, and for both haemorrhagic and non-haemorrhagic erosions. The mean gastric body Lanza score for mucosal damage was lower after ECC than ASA (p = 0.003). The visual analogue score for gastric body damage was lower for ECC (16.9 mm (15.9)) than for ASA (32.7 mm (20.8)), p = 0.008. Serum salicylate concentrations were similar after both preparations (ASA: 66 (23) mg/l, versus ECC: 58 (17) mg/l, NS). Serum thromboxane B2 was similarly reduced using both preparations-97.2 (3.5)% inhibition with ASA, 95.2 (5.5)% inhibition with calcium carbasalate (NS). Suppression of gastric mucosal PGE2 synthesis was similar with both preparations (ASA: 83.4 (17.1)%; ECC 84.3 (12.9)%; NS). It is concluded that ECC causes significantly less gastroduodenal mucosal damage than ASA administered at bioequivalent doses as judged by serum salicylate, serum thromboxane, and mucosal PGE2 values. ECC may therefore be a less harmful alternative treatment to plain ASA. PMID:8566836

Combination chemotherapy with S-1 and cisplatin(S-1/CDDP)has become the standard treatment for gastric cancer, but the effect for hepatocellular carcinoma has not become clear. We experienced a case with advanced gastric cancer and hepatocellular carcinoma at the same time. We used S-1/CDDP as neoadjuvant chemotherapy for the case and performed surgical resection of the gastric cancer and hepatocellular carcinoma. From histological examination of the resected specimen, we may be able to prove that the S-1/CDDP chemotherapy for the hepatocellular carcinoma was also effective. A 57-year-old man visited our hospital with epigastralgia. Further examinations revealed a type-3 advanced gastric cancer with bulky N2 and hepatocellular carcinoma at segment 5. The gastric cancer was thought to be too advanced for initial surgery, so we performed S-1/CDDP chemotherapy(S-1 100 mg/body/day, CDDP 20 mg/body twice/week for 2 weeks)as preoperative therapy. After remarkable shrinkage of the gastric cancer was obtained, we performed distal gastrectomy, D2+a lymph node excision, liver S5 segmentectomy and cholecystectomy. The histological examination showed remarkable denaturation and necrosis as grade 2 effectiveness in over two-thirds of the hepatocellular carcinoma area and grade 1b in gastric cancer according to the Japanese classification of gastric carcinoma. This result suggests that S-1/CDDP chemotherapy might therefore be effective as systemic therapy for patients with hepatocellular carcinoma. However, further clinical trials are required.

Gastric bypass results in greater weight loss than Vertical banded gastroplasty (VBG), but the underlying mechanisms remain unclear. In addition to effects on energy intake the two bariatric techniques may differentially influence energy expenditure (EE). Gastric bypass in rats increases postprandial EE enough to result in elevated EE over 24 hours. This study aimed to investigate alterations in postprandial EE after gastric bypass and VBG in humans. Fourteen women from a randomized clinical trial between gastric bypass (n = 7) and VBG (n = 7) were included. Nine years postoperatively and at weight stability patients were assessed for body composition and calorie intake. EE was measured using indirect calorimetry in a respiratory chamber over 24 hours and focused on the periods surrounding meals and sleep. Blood samples were analysed for postprandial gut hormone responses. Groups did not differ regarding body composition or food intake either preoperatively or at study visit. Gastric bypass patients had higher EE postprandially (p = 0.018) and over 24 hours (p = 0.048) compared to VBG patients. Postprandial peptide YY (PYY) and glucagon like peptide 1 (GLP-1) levels were higher after gastric bypass (both p<0.001). Gastric bypass patients have greater meal induced EE and total 24 hours EE compared to VBG patients when assessed 9 years postoperatively. Postprandial satiety gut hormone responses were exaggerated after gastric bypass compared to VBG. Long-term weight loss maintenance may require significant changes in several physiological mechanisms which will be important to understand if non-surgical approaches are to mimic the effects of bariatric surgery.

Urea breath test (UBT) using an infrared spectral analyzer is widely used for non-invasive and rapid detection of gastric Helicobacter spp. in human, but not veterinary medicine. The main purposes of this study were to determine the reference range of the UBT in dogs and to evaluate its clinical usefulness. To address the first aim, 6 healthy laboratory beagles were subjected to UBT and upper gastrointestinal endoscopy. Gastric endoscopic biopsy samples from the antrum, corpus and fundus were examined for Helicobacter spp. by polymerase chain reaction (PCR) testing, rapid urease test (RUT), histology and cytology. Amoxicillin, metronidazole and omeprazole were given to infected dogs for 14 days, and dogs that became Helicobacter-negative were used to determine the reference range for UBT. To address the second aim, 32 canine patients underwent UBT before upper gastrointestinal endoscopy, and the sensitivity and specificity of UBT were calculated based on our newly determined reference range using PCR as the gold standard for detection of Helicobacter spp. Initially, all 6 laboratory beagles were infected in all gastric regions and became uninfected after eradication. The mean ± 2 SD UBT value after eradication was 0.6 ± 1.8‰, and the reference range for UBT was determined to be less than 2.5‰. UBT was completed successfully in 27 patients. Using our reference range, UBT displayed 89% (16/18) sensitivity and 89% (8/9) specificity, indicating that UBT was quite useful for the detection of gastric Helicobacter spp. infection in dogs.

The development of gastric dysplasia and neoplasia in patients with pernicious anaemia has been evaluated in a prospective clinical and endoscopic follow up study. After initial screening of 80 patients between 1978 and 1980, one patient underwent total gastrectomy for a gastric malignancy and 12 were kept under surveillance and underwent endoscopy at a mean interval of 14 months. In the remaining 67 patients further investigation was attempted six to seven years after the initial investigation. The continuous follow up study identified carcinoids in one patient and an adenoma with severe dysplasia in a further patient. The grade and site of mucosal dysplasia differed from one investigation to the next, but no overall progression was observed. Of the 79 patients, eight had died by the time of the reinvestigation, two of unknown cause and six of causes unrelated to pernicious anaemia. In 38 of the remaining 71 patients, clinical data only were available, with no evidence of new gastric malignancy. In 27 patients it was possible to perform an upper gastrointestinal endoscopy, when no change in the degree of dysplasia was detected. In six patients no follow up information was obtainable. In conclusion, patients with pernicious anaemia should be investigated by upper gastrointestinal endoscopy soon after diagnosis. Polyps should be removed wherever possible. In the presence of severe mucosal dysplasia or polyps that are not removed, frequent reinvestigation should be performed, provided the patient is eligible for gastric surgery. In the remaining patients, follow up endoscopies at about five year intervals would seem sufficient. PMID:2083855

One hundred and seventy-six students free of gastrointestinal disease were studied to establish normal acid secretion values for healthy male and female students by the augmented histamine test and to re-examine the relationship between gastric acid secretion and ABO blood groups, body weight, fat-free body mass, height, degree of ectomorphy and mesomorphy, the number of cigarettes smoked per day, and serum cholesterol. A prospective study was then carried out on gastric acid secretion and the subsequent development after 10 years of duodenal ulcers or dyspepsia. Young, healthy medical students have a fairly high mean basal and maximal acid output. There was very little difference in the mean acid outputs of the various ABO blood groups. A significant correlation was shown between acid output and body weight and fat-free body mass, but not with the other measurements of body build. Basal acid output was also related to the number of cigarettes smoked per day. Three students who subsequently developed duodenal ulcers all had a preexistent high level of acid secretion. The acid output was, however, similar in the groups who developed significant or minor dyspepsia or who remained asymptomatic. PMID:4696532

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. PMID:29430223

A 69-year-old man was admitted to our hospital with complaints of loss of appetite, fatigue and dysphasia. Upper gastroscopy revealed advanced gastric cancer. Abdominal CT suggested liver metastases. At first we thought the liver metastases has been completely resected, but we found multiple liver metastases unexpectedly. So only total gastric resection and liver biopsy were performed. The pathological diagnosis was metastatic carcinoma. Paclitaxel (PTX) and S-1 combination chemotherapy was started after operation and was continued for 42 courses. A CT scan showed a complete response, and he has been well without tumor re-growth ever since. The combination of PTX and S-1 not only may be an effective regimen for gastric cancer with liver metastases, but also can be used without side effects for a long time.

A 56-year-old woman with recurrent gastric cancer treated with PMU therapy, combined CDDP 75 mg/m2 i.v. MMC 10 mg/body i.v. and UFT 400mg/body/2 alpha/day p.o., was reported. She was admitted because of cervical lymph node swelling and abdominal tumor (para-aorta lymph node swelling). She was treated two times with this therapy and induced into complete remission. The serum CEA level, more than 500 ng/ml before the treatment, was reduced to 6.7 ng/ml after treatment. She has currently been free of disease for more than four weeks. We conclude that this PMU therapy is extremely effective for indurable gastric cancer.

A 76-year-old man was admitted to our hospital for treatment of gastric tube cancer(cT2N0M0, cStage II A)detected by a screening upper gastrointestinal endoscopy. Seven years previously, he had undergone subtotal esophagectomy for esophageal cancer with gastric pull-up via the retrosternal route. At that time, he experienced cardiopulmonary arrest due to ventric- ular tachycardia. He was in a state of poor nutrition(BMI 15 kg/m2). Therefore, reducing operative stress as much as possible, minimizing complications after surgery, and aiming for a satisfactory postoperative course are all important goals. Based on his past history, we performed distal gastrectomy(resection of the distal part of the gastric tube)without excision of the right gastroepiploic artery. The postoperative course was uneventful. He was discharged 40 days after surgery. By considering the risks of surgery due to cardiac dysfunction and malnutrition, we were able to provide effective and safe therapy for the patient.

Clinical features of gastroduodenal injury associated with long-term low-dose aspirin therapy

Low-dose aspirin (LDA) is clinically used for the prevention of cardiovascular and cerebrovascular events with the advent of an aging society. On the other hand, a very low dose of aspirin (10 mg daily) decreases the gastric mucosal prostaglandin levels and causes significant gastric mucosal damage. The incidence of LDA-induced gastrointestinal mucosal injury and bleeding has increased. It has been noticed that the incidence of LDA-induced gastrointestinal hemorrhage has increased more than that of non-aspirin non-steroidal anti-inflammatory drug (NSAID)-induced lesions. The pathogenesis related to inhibition of cyclooxygenase (COX)-1 includes reduced mucosal flow, reduced mucus and bicarbonate secretion, and impaired platelet aggregation. The pathogenesis related to inhibition of COX-2 involves reduced angiogenesis and increased leukocyte adherence. The pathogenic mechanisms related to direct epithelial damage are acid back diffusion and impaired platelet aggregation. The factors associated with an increased risk of upper gastrointestinal (GI) complications in subjects taking LDA are aspirin dose, history of ulcer or upper GI bleeding, age > 70 years, concomitant use of non-aspirin NSAIDs including COX-2-selective NSAIDs, and Helicobacter pylori (H. pylori) infection. Moreover, no significant differences have been found between ulcer and non-ulcer groups in the frequency and severity of symptoms such as nausea, acid regurgitation, heartburn, and bloating. It has been shown that the ratios of ulcers located in the body, fundus and cardia are significantly higher in bleeding patients than the ratio of gastroduodenal ulcers in patients taking LDA. Proton pump inhibitors reduce the risk of developing gastric and duodenal ulcers. In contrast to NSAID-induced gastrointestinal ulcers, a well-tolerated histamine H2-receptor antagonist is reportedly effective in prevention of LDA-induced gastrointestinal ulcers. The eradication of H. pylori is equivalent to treatment with omeprazole in preventing recurrent bleeding. Continuous aspirin therapy for patients with gastrointestinal bleeding may increase the risk of recurrent bleeding but potentially reduces the mortality rates, as stopping aspirin therapy is associated with higher mortality rates. It is very important to prevent LDA-induced gastroduodenal ulcer complications including bleeding, and every effort should be exercised to prevent the bleeding complications. PMID:23555156

Epidemiological data on green/jasmine tea and esophageal as well as gastric cancer are limited and inconclusive. In order to study the effect of jasmine tea in upper gastrointestinal (UGI) cancers, we evaluated 600 esophageal squamous cell carcinoma (ESCC), 598 gastric cardia cancer (GCA), and 316 gastric non-cardia cancer (GNCA) cases and 1,514 age-, gender-, and neighborhood-matched controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated from logistic regression adjusted for matching factors and potential confounders. Among controls, 35% of males and 8% of females reported consumption of jasmine tea; other tea consumption was rare. Consumption of jasmine tea (ever vs. never) was not associated with risk of ESCC (OR = 1.15, 95% CI 0.92–1.44), GCA (OR = 1.14, 95% CI 0.88–1.37), or GNCA (OR = 0.85, 95% CI 0.64–1.15) in males and females combined. Among males, cumulative lifetime consumption showed a significant positive dose–response relation with ESCC risk, but not for GCA and GNCA. In exploratory analyses, occupation affected the relation between tea and ESCC such that consumption in males was associated with increased risk only in non-office workers. Overall, we found no evidence for a protective effect of tea in esophageal or gastric cancer. Further studies of the potential effects of thermal damage, tea quality, and water quality on UGI cancers are suggested.

The effect of palm vitamin E on the healing of ethanol-induced gastric lesion was compared with ranitidine. Fifty-six male rats of Sprague-Dawley species (200–250 g of weight) were randomly divided into three groups (N = 14). Gastric mucosal injury was induced by orogastric tube administration of 0.5 ml 100% ethanol. Immediately after induction, Group I (k) rats was fed with a normal diet (control), group II (p) was fed palm vitamin E enriched diet (150 mg/kg food), Group III(r) was treated with ranitidine 30 mg/kg body weight intraperitoneally and Group IV (p + r) was fed with palm vitamin E and treated with ranitidine 30 mg/kg body weight intraperitoneally of the same dose. The rats were killed at the end of 1 week and 3 weeks of treatment or feeding. The rate of gastric healing was faster in palm vitamin E treated group compared to control and ranitidine treated groups as shown by a lower mean ulcer index. The effect was seen as early as the first week of treatment whereas ranitidine did not show any healing effect even after 3 weeks of therapy. Neither gastric acidity nor gastric mucus production are involved in gastroprotective effect of palm vitamin E. The most probable mechanism is via reducing lipid peroxidation process as shown by a significant decrease in gastric MDA PMID:10607016

Previous studies describe a relationship between pannus mass and panniculectomy-related complication rates. Patient management may be improved by elucidating the key factors influencing pannus formation. A retrospective review was conducted of 135 patients who had undergone laparoscopic Roux-en-Y gastric bypass from 1996 to 2010 and subsequent panniculectomy. Outcome measures included age, sex, body mass index, time of surgery, resected pannus mass, comorbidities, and panniculectomy-related complications. Nonparametric continuous and nominal variables were assessed using Spearman rank-correlation and Mann-Whitney U tests, respectively. One hundred thirty-five patients (123 women and 12 men; mean age, 44.7 years) were included in analysis. All patients had body contouring surgery more than 1 year after bariatric surgery (median time interval, 2.1 years). Median body mass index at the time of bypass, 1 year after bypass, and at the time of body contouring surgery was 48.7, 30.0, and 29.4 kg/m, respectively. Median pannus mass was 2.2 kg. Larger pannus mass was associated with greater age at gastric bypass surgery (p = 0.034), higher pre-gastric bypass body mass index (p = 0.031), higher prepanniculectomy body mass index (p < 0.001), and longer time interval between gastric bypass and panniculectomy (p = 0.046). Female patients requiring blood transfusions had a significantly larger pannus mass than those who did not (p = 0.048). Performing bariatric surgery on patients at a younger age or having patients reduce body mass index as much as possible before bariatric surgery may be useful for minimizing symptomatic pannus formation and in turn may decrease rates of panniculectomy-related complications.

No gastric mill in sauropod dinosaurs: new evidence from analysis of gastrolith mass and function in ostriches

PubMed Central

Wings, Oliver; Sander, P. Martin

2006-01-01

Polished pebbles occasionally found within skeletons of giant herbivorous sauropod dinosaurs are very likely to be gastroliths (stomach stones). Here, we show that based on feeding experiments with ostriches and comparative data for relative gastrolith mass in birds, sauropod gastroliths do not represent the remains of an avian-style gastric mill. Feeding experiments with farm ostriches showed that bird gastroliths experience fast abrasion in the gizzard and do not develop a polish. Relative gastrolith mass in sauropods (gastrolith mass much less than 0.1% of body mass) is at least an order of magnitude less than that in ostriches and other herbivorous birds (gastrolith mass approximates 1% of body mass), also arguing against the presence of a gastric mill in sauropods. Sauropod dinosaurs possibly compensated for their limited oral processing and gastric trituration capabilities by greatly increasing food retention time in the digestive system. Gastrolith clusters of some derived theropod dinosaurs (oviraptorosaurs and ornithomimosaurs) compare well with those of birds, suggesting that the gastric mill evolved in the avian stem lineage.

Microbiota in human alimentary tract plays important roles for homeostatic maintenance of the body. Compositional difference of gut microbiota is tightly associated with susceptibility of many diseases, including inflammatory diseases, obesity, diabetes mellitus, cancer, and atherosclerosis. "Dysbiosis" refers to a state of imbalance among the colonies of microorganisms within the body, which brings abnormal increase of specific minor components and decrease in the normally dominant species. Since stomach secrets strong acid for its digestive role, this organ has long been thought a sterile organ. However, the discovery of Helicobacter pylori (H. pylori) has changed the concept. This bacterium has proven to cause gastritis, peptic ulcer, and gastric cancer. However, recent cross-sectional studies revealed that H. pylori carriers had a decreased risk of developing immunological diseases, such as asthma. H. pylori coinfection also suppresses inflammatory bowel diseases. This review describes human gastric microbiota by discussing its mutual interaction and pathogenic enrollment. Gastric "dysbiosis" may affect host inflammatory response and play important role for gastric pathogenesis. We will topically discuss enrollment of dysbiosis for genesis of gastric cancer as well as for disruption of immunological homeostasis affecting oncogenic resistance.

The effect of Helicobacter mustelae infection on gastric epithelial proliferation was studied in ferrets colonized with H.mustelae and specific pathogen-free (SPF) ferrets not infected with H.mustelae. Thirteen H. mustelae-infected ferrets between the ages of 13 and 32 months and 16 SPF ferrets between 6 and 18 months were analyzed. Bacterial cultures, urease tests and Warthin-Starry stains were used to identify H.mustelae. Tissues obtained from the antrum and the body regions of the stomach were assayed by proliferating cell nuclear antigen (PCNA) immunohistochemistry and measured using a computerized color image analysis system. PCNA-expressing gastric epithelia in the antrum and the body regions were significantly increased in the H.mustelae-infected ferrets versus the SPF ferrets (P < 0.001). PCNA positivity in the antrum regions of both the H.mustelae-infected ferrets and SPF ferrets was significantly higher than that of the body regions (P < 0.001). Comparison of the histopathology of infected ferrets indicated that PCNA positivity correlated with the histological severity of gastritis. This study suggests that cell proliferation in ferret gastric mucosa increases with H.mustelae infection and provides evidence that PCNA is a useful biomarker for studying the changes in cell kinetics in the ferret stomach. The data also further support the use of the H.mustelae-infected ferret as an animal model for studying the pathogenesis of Helicobacter pylori-induced gastric diseases of humans.

Acute upper gastrointestinal (GI) bleeding is a common medical emergency. A common risk factor of upper GI bleeding is cirrhosis of liver, which can lead to variceal haemorrhage. 30-40% of cirrhotic patients who bleed may have non-variceal upper GI bleeding and it is frequently caused by peptic ulcers, portal gastropathy, Mallory-Weiss tear, and gastroduodenal erosions. The objective of this study was to determine the frequency of upper gastrointestinal endoscopic findings among patients presenting with upper gastrointestinal bleeding with liver cirrhosis. This descriptive cross-sectional study was carried out in Gastroenterology & Hepatology Department of Ayub Teaching Hospital, Abbottabad from February 2012 to June 2013. 252 patients diagnosed with cirrhosis, presenting with upper GI bleed, age 50 years of either gender, and were included in the study. Non-probability consecutive sampling was used, Endoscopy was performed on each patient and the findings documented. The mean age was 57.84 +/- 6.29 years. There were 158 (62.7%) males and 94 (37.3%) females. The most common endoscopic finding was oesophageal varices (92.9%, n=234) followed by portal hypertensive gastropathy (38.9%, n=98) with almost equal distribution among males and females. Gastric varices were found in 33.3% of patients (n=84). Among other non-variceal lesions, peptic ulcer disease was seen in 26 patients (10.3%) while gastric erosions were found in 8 patients (3.2%). In patients with acute upper GI bleeding and liver cirrhosis, the most common endoscopic finding is oesophageal varices, with a substantially higher value in our part of the country, apart from other non-variceal causes.

Hyperventilation and aerophagia: a negative report.

Folgering, H; Sistermans, H

Aerophagia is described as a frequent symptom in the hyperventilation syndrome. However, this has never been substantiated. In this study the extent of air swallowing was estimated from the size of the gastric air-bubble on the chest X-ray, in a group of 62 hyperventilators and in a group of 62 normals. No differences were found between the mean amounts of gastric air in the two groups. Women in both groups seemed to swallow more air than men. The amount of air was not related to the time of the day (meals). In 15 hyperventilators the subjective complaints of upper abdominal discomfort and of chest pain were quantified: no correlation was found with the amount of gastric air.

Whether gastrointestinal motor and sensory function is primary cause or secondary effect of abnormal body weight is uncertain. Moreover, studies relating continuous postprandial sensations of satiation to measurable pathology are scarce. This work assessed postprandial gastrointestinal function and concurrent sensations of satiation across a wide range of body weight and after weight change. Patients with anorexia nervosa (AN) and obesity (OB) were investigated in reference to normal weight controls (HC). AN were additionally investigated longitudinally. Gastric emptying, antral contractions and oro-cecal transit after ingestion of a solid meal were investigated by MRI and 13 C-lactose-ureide breath test. The dependency of self-reported sensations of satiation on the varying degree of stomach filling during gastric emptying was compared between groups. 24 AN (BMI 14.4 (11.9-16.0) kg/m 2 ), 16 OB (34.9 (29.6-41.5) kg/m 2 ) and 20 HC (21.9 (18.9-24.9) kg/m 2 ) were studied. Gastric half-emptying time (t 50 ) was slower in AN than HC (p = 0.016) and OB (p = 0.007), and a negative association between t 50 and BMI was observed between BMI 12 and 25 kg/m 2 (p = 0.007). Antral contractions and oro-cecal transit were not different. For any given gastric content volume, self-reported postprandial fullness was greater in AN than in HC or OB (p < 0.001). After weight rehabilitation, t 50 in AN tended to become shorter (p = 0.09) and postprandial fullness was less marked (p < 0.01). A relationship between body weight and gastric emptying as well as self-reported feelings of satiation is present. AN have slower gastric emptying and heightened visceral perception compared to HC and OB. Longitudinal follow-up after weight rehabilitation in AN suggests these abnormalities are not a primary feature, but secondary to other factors that determine abnormal body weight.

To clarify the usefulness of (18)F-FDG PET/CT for detecting primary gastric cancer via gastric distention using a mixture of milk and Diatrizoate Meglumine. A total of 68 patients (male: 47, female: 21; age: 41-87 years) suspected of gastric carcinoma underwent (18)F-FDG PET/CT imaging. After whole-body PET/CT imaging in a fasting state, the patients drank a measured amount of milk with Diatrizoate Meglumine. Local gastric district PET/CT imaging was performed 30 min later. The imaging was analyzed by semi-quantitative analysis, standardized uptake value (SUV) of the primary tumor was measured in a region of interest. The diagnosis results were confirmed by gastroscopy, pathology, and follow-up results. Of the 68 patients, 56 malignant gastric neoplasm patients (male: 37, female: 19) were conformed. The sensitivity, specificity, positive predictive value and negative predictive value of fasting whole-body PET/CT imaging for a primary malignant tumor were 92.9%, 75.0%, 94.5%, and 69.0%, respectively. The values for distension with a mixture of milk and Diatrizoate Meglumine were 91.1%, 91.7%, 98.1%, and 68.8%, respectively. The area under the curve was 0.919 ± 0.033 and 0.883 ± 0.066 for the diagnosis of gastric cancer with SUVmax in a fasting state and after intake of mixture respectively, the differences were not statistically significant (P=0.359). Using gastric distension with a mixture of milk and Diatrizoate Meglumine, the mean ratio of the lesion's SUVmax to the adjacent gastric wall SUVmax increased significantly from 3.30 ± 3.05 to 13.50 ± 15.05, which was statistically significant (P<0.001). (18)F-FDG PET/CT imaging is highly accurate for the diagnosis of primary gastric carcinoma. Gastric distention can display the lesions more clearly, however, it cannot significantly improve diagnostic accuracy. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

This article reviews the sex differences in upper gastrointestinal (GI) motility for both healthy and common dysmotility conditions. It focuses on gastroesophageal reflux disease and other esophageal motor disorders for the esophagus and on gastroparesis and accelerated gastric emptying for the stomach. It also describes differences in upper GI motility signs and symptoms during each female hormonal stage (ie, menstrual cycle, pregnancy, perimenopause, menopause) for both healthy participants and those suffering from one of the aforementioned upper GI dysmotility conditions. More research still needs to be conducted to better understand sex differences in upper GI motility. Copyright © 2016 Elsevier Inc. All rights reserved.

Background and Aims Gastric bypass results in greater weight loss than Vertical banded gastroplasty (VBG), but the underlying mechanisms remain unclear. In addition to effects on energy intake the two bariatric techniques may differentially influence energy expenditure (EE). Gastric bypass in rats increases postprandial EE enough to result in elevated EE over 24 hours. This study aimed to investigate alterations in postprandial EE after gastric bypass and VBG in humans. Methods Fourteen women from a randomized clinical trial between gastric bypass (n = 7) and VBG (n = 7) were included. Nine years postoperatively and at weight stability patients were assessed for body composition and calorie intake. EE was measured using indirect calorimetry in a respiratory chamber over 24 hours and focused on the periods surrounding meals and sleep. Blood samples were analysed for postprandial gut hormone responses. Results Groups did not differ regarding body composition or food intake either preoperatively or at study visit. Gastric bypass patients had higher EE postprandially (p = 0.018) and over 24 hours (p = 0.048) compared to VBG patients. Postprandial peptide YY (PYY) and glucagon like peptide 1 (GLP-1) levels were higher after gastric bypass (both p<0.001). Conclusions Gastric bypass patients have greater meal induced EE and total 24 hours EE compared to VBG patients when assessed 9 years postoperatively. Postprandial satiety gut hormone responses were exaggerated after gastric bypass compared to VBG. Long-term weight loss maintenance may require significant changes in several physiological mechanisms which will be important to understand if non-surgical approaches are to mimic the effects of bariatric surgery.

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 < 0.001), and median percent retention at 2 h was 63.8 versus 20.2 (p < 0.001). In multivariate analysis, parameters that affected gastric emptying T ½ time were found as serum gastrin level (OR 1.002, 95 % CI 1.001-1.004, p < 0.001, chronic inflammation (OR 3.689, 95 % CI 1.44-9.39, p < 0.001), and increase in the degree of the atrophy of the gastric mucosa (OR 8.96, 95 % CI 2.98-26.93, p < 0.001). In patients with autoimmune 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.

Although hypo- and hyperthyroid patients have different symptoms in the gastrointestinal tract, the mechanism of thyroid action on the gut remains poorly understood. Thus the aim of this study was to investigate the effect of hypo- and hyperthyroidism on gastric myoelectrical activity, gastric emptying, dyspeptic symptoms. Twenty-two hyperthyroid (median age 45, 15 females) and 11 hypothyroid (median age 42, 10 females) patients were included into the study. Dyspepsia score, hypo- and hyperthyroid symptom scale, abdominal ultrasonography and upper gastrointestinal endoscopy were performed. Gastric myoelectrical activity was measured by electrogastrograpy (EGG) before and after therapy both preprandially and postprandially and compared with age, gender, and body-matched controls (12 for hypothyroid, 15 for hyperthyroid patients). Radionuclide gastric emptying studies were performed with a solid meal. Hypothyroid patients revealed a significant increase in preprandial tachygastria as compared with controls (12.3% vs 4.8%). The percentage of preprandial normal slow waves (2.4-3.7 cpm) was below 70% (dysmotility) in 7 of 11 hypothyroid patients versus 2 of 12 controls (P < 0.05). Hyperthyroid patients revealed a significantly higher preprandial (3.1 vs 2.8) and postprandial (3.4 vs 3) DF when compared with the controls (P < 0.05). A higher percentage of postprandial taschygastria (7.9 vs 0) was present in hyperthyroid patients than in the controls (P < 0.05). The decrease on postprandial EGG power (power ratio < 1) was observed in 7 patients the in hyperthyroid group and 1 in controls (P < 0.05). The percentage of postprandial normal slow waves was below 70% in 10 of 20 hyperthyroid patients vs 1 of 15 controls (P < 0.05). After therapy these differences disappeared in the euthyroid state. The hypo- and hyperthyroid symptom scale correlated to dyspepsia score. Dyspepsia score in hyperthyroidism correlated to power ratios in hyperthyroid patients. We detected some correlations between serum levels of fT3 or fT4 and some EGG parameters in hypo- and hyperthyroidism. Dyspepsia score and hypo- and hyperthyroid symptom scale were improved significantly after therapy in the euthyroid state. In conclusions, we showed gastric dysrhythmia by EGG in both hypo- and hyperthyroid patients. Dyspeptic symptoms correlated to the activity of thyroid disease. After therapy, these findings and dyspeptic symptoms improved in the euthyroid state. Abnormalities of power ratios may be responsible of dyspeptic symptoms in hyperthyroid patients. EGG may be a useful and noninvasive tool for detecting gastric disturbances during hypo- and hyperthyroidism.

Heterotopic gastric mucosa (HGM) of the esophagus is a congenital anomaly consisting of ectopic gastric mucosa. It may be connected with disorders of the upper gastrointestinal tract, exacerbated by Helicobacter pylori. The diagnosis of HGM is confirmed via endoscopy with biopsy. Histopathology provides the definitive diagnosis by demonstrating gastric mucosa adjacent to normal esophageal mucosa. HGM located in the distal esophagus needs differentiation from Barrett's esophagus. Barrett's esophagus is a well-known premalignant injury for adenocarcinoma of the esophagus. Malignant progression of HGM occurs in a stepwise pattern, following the metaplasia-dysplasia-adenocarcinoma sequence.We present a rare case of a teenage girl with HGM located in the distal esophagus, associated with chronic gastritis and biliary duodenogastric reflux. Endoscopy combined with biopsies is a mandatory method in clinical evaluation of metaplastic and nonmetaplastic changes within HGM of the esophagus.

Esophagogastroduodenoscopy (EGD) is a commonly used, safe diagnostic modality for evaluation of epigastric pain and rarely its major complications include perforation, haemorrhage, dysrhythmias and death. Gastric volvulus has been reported to complicate percutaneous endoscopic gastrostomy but its occurrence after diagnostic EGD has not yet been reported in literature. The successful management relies on prompt diagnosis and gastric untwisting, decompression and gastropexy or gastrectomy in full thickness necrosis of the stomach wall. A 38-year-old woman presented with epigastric pain and EGD showed pangastritis. Immediately after EGD she developed increased severity of pain, vomiting and abdominal distension. Emergency laparotomy carried out for peritoneal signs revealed eventration of left hemidiaphragm with the stomach twisted anticlockwise in the longitudinal axis. After gastric decompression and untwisting of volvulus, anterior gastropexy and gastrostomy was carried out. Hence, we report this rare complication of diagnostic endoscopy and review the existing literature on the management.

Corrosive-induced gastric outlet obstruction without oesphageal involvement: a case report.

The objective of this paper is to report an unusual case of isolated gastric outlet obstruction following corrosive ingestion. A case report of a 28-year old female seen by the authors. The literature on gastric outlet obstruction following ingestion of corrosives is reviewed briefly. Features of worsening gastric outlet obstruction were found in this 28-year old female five months after ingestion of hydrochloric acid. There was an antecedent history of depressive illness. The upper gastrointestinal barium contrast radiographs showed a normal oesophagus and proximal stomach. The distal stomach was however scarred, contracted with severe antropyloric stenosis. She underwent nutritional rehabilitation with high protein diet and made an uneventful recovery after a gastrojejunostomy. This case suggests a relative resistance of the oesophagus to corrosive acids as reported in the literature. The stomach, however, is more susceptible to acids causing burns with subsequent cicatrisation around the antrum and pylorus.

Acute bleeding from the upper gastrointestinal system is a medical emergency which is followed by high mortality rate, ranging from 6 to 15% in spite of modern diagnostic methods and treatment. Bleeding from the upper gastrointestinal system may be caused by gastrointestinal stromal tumors of the stomach, which are mainly characterized by occult bleeding, while profuse bleeding rarely occurs accompanied by hemorrhagic shock. Gastrointestinal stromal tumors of stomach are the most common mesenchimal tumors of the gastrointestinal tract. In our study we showed a 60-year-old female patient with profuse bleeding from the stomach and the clinical picture of severe hemorrhagic shock, caused by gastrointestinal stromal tumor. An ovoid junction, raised towards the lumen, covered with ulcerated mucosa in several places and followed by massive arterial bleeding was found intraoperatively, after the performed gastrotomy. Histopathological examination with immunohistochemical analysis confirmed that this was a gastrointestinal stromal tumor of the stomach. Acute bleeding from the digestive system is a sudden and serious condition of the body. Urgent esophagogastroduodenoscopy is a sensitive and specific diagnostic and therapeutic method of choice. Massive bleeding from the upper gastrointestinal tract is very rarely caused by gastrointestinal stromal tumors, whose clinical picture is very heterogeneous and depends on tumor size and location. Abundant bleeding from the tumor is an indication for urgent surgical intervention. According to the literature massive hemorrhage of the upper digestive system can rarely be caused by gastrointestinal stromal tumor of the stomach. It is shown that abundant hemorrhage of the upper digestive tract can be caused with gastric gastrointestinal stromal tumor. Surgical resection is the main form of treatment of gastrointestinal stromal tumors of the digestive system and bleeding from these tumors caused by failure of endoscopic hemostasis.

Our aim was to determine the EPIYA-cagA Phosphorylation sites and dupA gene in H. pylori isolates among patients with upper gastrointestinal diseases. Pathogenicity of the cagA-positive Helicobacter pylori is associated with EPIYA motifs and higher number of EPIYA-C segments is a risk factor of gastric cancer, while duodenal ulcer-promoting gene (dupA) is determined as a protective factor against gastric cancer. A total of 280 non-repeated gastric biopsies obtained from patients undergoing endoscopy from January 2013 till July 2013. Samples were cultured on selective horse blood agar and incubated in microaerophilic atmosphere. The isolated organisms were identified as H. pylori by Gram staining and positive oxidase, catalase, and urease tests. Various motif types of cagA and the prevalence of dupA were determined by PCR method. Out of 280 specimens, 128 (54.7%) isolated organisms were identified as H. pylori. Of 120 H. pylori isolates, 35.9% were dupA positive and 56.26% were cagA positive, while cagA with ABC and ABCC motifs were 55.5% and 44.5%, respectively. Fifty six percent of the isolates with the ABCC motif have had dupA genes. We also found a significant association between strains with genotypes of dupA-ABC and duodenal ulcer disease (p = 0.007). The results of this study showed that the prevalence of cagA-positive H. pylori in Shiraz was as high as in western countries and higher numbers of EPIYA-C segments were seen in gastric cancer patients. We may also use dupA as a prognostic and pathogenic marker for duodenal ulcer disease and cagA with the segment C for gastric cancer and gastric ulcer disease in this region.

Endoscopic submucosal dissection (ESD) is useful as a minimally invasive treatment option for early gastric cancer. ESD is also used in the management of postoperative remnant gastric cancers in the stomach and gastric tube cancers. Perforation and delayed bleeding have been the main complications of ESD reported in the management of gastric tube cancer. However, in the current literature, there is no description of precordial skin burns caused by electrical coagulation. While we treated 22 patients with gastric tube cancers by ESD from 2005 to 2014, we experienced five skin burns in four patients after ESD. We retrospectively analyzed clinical characteristics of precordial skin burn as a complication of ESD. All skin burns occurred in patients reconstructed using a presternal route, whose incidence of precordial skin burn was 55.6%. In all cases, lesions were located in the upper or middle third of gastric tubes irrespective of their direction. Skin burn developed on postoperative day (POD) 1 or POD 2, taking 4-7 days to heal and was accompanied by high fever in 60% of cases. The present study suggests that when carrying out ESD for gastric tube cancer using the presternal route, it is necessary to consider the occurrence of a precordial skin burn as a possible complication. © 2015 The Authors.

To evaluate the efficacy of 5 mL simethicone solution in decreasing gastric foam if given at least 30 min before gastroscopy. This was a randomized, placebo controlled, endoscopist blinded study performed at Changi General Hospital. Patients were at least 21 years old, had no prior surgical resection of the upper gastrointestinal tract, and scheduled for elective diagnostic gastroscopies. The primary outcome was the total mucosal visibility score (TMVS) which was evaluated using McNally score. The sample size was calculated to be 24 per group (SD 2.4, 80% power, P < 0.05, 2-sample t test). Fifty-four patients were randomised to receive either simethicone [1 mL liquid simethicone (100 mg) in 5 mL of water] or placebo (5 mL of water) at least 30 min before their gastroscopy. Six accredited consultants conducted the gastroscopy, and the interobserver agreement of scoring TMVS was good with a Kappa statistic of 0.73. The simethicone group had significantly better mean TMVS compared to placebo (5.78 ± SD 1.65 vs 8.89 ± SD 1.97, P < 0.001). The improvement was statistically significant for the duodenum and the gastric antrum, angularis, body, and fundus. Percent 51.9 of patients in the simethicone group had a TMVS of 4 (no bubbles at all) to 5 (only 1 area with minimal bubbles), while in the placebo group 3.7% of patients had TMVS of 4 or 5. The number needed to treat was 2.1 to avoid a TMVS of 6 and more. The simethicone group also had a significantly shorter procedure time with less volume of additional flushes required during gastroscopy to clear away obscuring gastric foam. With a premedication time of at least 30 min, 5 mL simethicone can significantly decrease gastric foam, decrease the volume of additional flushes, and shorten gastroscopy time.

To evaluate whether the presence of a gastric foreign body (gFB) is a significant risk factor for gastric dilatation and volvulus (GDV) in dogs and to quantify the change in likelihood of developing GDV associated with the presence of a gFB. Retrospective case-control study. 118 large- or giant-breed dogs treated surgically for an episode of GDV and 342 large- or giant-breed dogs (> 12 months old) that underwent abdominal surgery for reasons other than GDV. During exploratory celiotomy, all dogs underwent palpation and visual examination of the entire gastrointestinal tract. A foreign body was defined as nondigestible or slowly digestible material palpated during gastrointestinal tract examination that was causing clinical signs or was > 10 cm in length or > 2 cm in width. The incidence of gFBs was significantly higher in the group of dogs with GDV. The presence of a gFB, age, weight, and purebred status were significant risk factors for GDV. Odds ratios were calculated for gFB (OR, 4.920), age (OR, 1.157), weight (OR, 0.958) and purebred status (OR, 4.836). Gastric foreign body was found to be a significant risk factor for GDV in dogs. The study findings suggested that a large- or giant-breed dog with a gFB was approximately 5 times as likely to develop GDV as a similar dog with no gFB. Results indicated that there was a strong correlation between gFB and GDV in dogs. However, further cohort studies are needed to determine whether there is a causal relationship between the presence of a gFB and the development of GDV in dogs.

to evaluate the thickness of the gastric wall at the time of intra gastric balloon (IGB) placement, at the time of its withdrawal and one month after withdrawal. fifteen morbidly obese patients underwent the introduction of IGB under general anesthesia. In all patients, there was infusion of 500ml of distilled water in the balloon for the test. Measurements of the thickness of the gastric wall were made in the antrum, body and proximal body, using a radial echoendoscope with a frequency of 12MHz and maximum zoom, and its own balloon inflated with 5ml of distilled water. the presence of IGB led to increased wall thickness of the gastric body by expanding the muscle layer. These changes were apparently transient, since 30 days after the balloon withdrawal there was a tendency to return of the wall thickness values ​​observed before the balloon insertion. the use of intragastric balloon for the treatment of obesity determines transient increase in the wall thickness of the gastric body caused by expanded muscle layer. A preocupação com a melhoria dos resultados estéticos e funcionais sem comprometimento dos resultados oncológicos na cirurgia de cabeça e pescoço tem aumentado significativamente. Os procedimentos minimamente invasivos e principalmente aqueles que utilizam a tecnologia robótica permitiram o desenvolvimento de novas abordagens, incluindo o acesso retroauricular, que agora é usado rotineiramente, especialmente na Coréia do Sul. A presente nota irá ilustrar a técnica e a experiência inicial na América Latina, demonstrando que esta abordagem é viável, segura e eficaz oncologicamente, podendo ser utilizada em casos selecionados com um benefício estético evidente.

Gastric erosion is widespread side effect of nonsteroidal anti-inflammatory drugs. To examine the complexity of the brain-gut axis regulation, indomethacin-induced gastric erosion formation was studied in connection with somatic and behavioral changes. During a constant telemetric recording of heart rate, body temperature, and locomotion of male rats we examined the effects of 24 h fasting, indomethacin (35 mg/kg s.c.) injection, and refeeding at 4 h. Behavior was analyzed on elevated plus maze (EPM) at 24 h and somatic changes at 72 h. Gastric erosion developed 4 h after indomethacin injection, healed 72 h later contrasted by large injury in the small intestine. As classical signs of chronic stress, body and thymus weight were reduced while adrenal weight was enhanced 72 h after indomethacin injection. Fasting by itself changed all telemetrically recorded parameters with most prominent decrease in heart rate. Indomethacin induced similar diminishing effects with earliest and strongest temperature decrease. As a sign of more anxious phenotype locomotion reducing effect of indomethacin injection was detected on EPM. The EPM-induced temperature elevation was missing in indomethacin-treated animals. Fasting by itself induce somatic changes, which can make the animals more vulnerable to ulcerogenic stimuli. Development of indomethacin-induced gastrointestinal lesions happened in parallel with disturbances of heart rate, core body temperature, and chronic stress-like somatic changes as well as anxiety-like behavior. We have to be more aware of the existence of the brain-gut axis and should study changes in the whole body rather than focusing on a specific organ. elevated plus maze.

This video demonstrates laparoscopic band-separated one anastomosis gastric bypass-combining the advantages of banding and gastric bypass without stapler and cutter use. This is basically a gastrojejunal loop bypass above an obstructive band in the upper stomach. An adjustable low pressure "Medsil" gastric band was introduced in the abdomen and retracted through the retrogastric tunnel. The front wall of the stomach below the band was displaced in the upward direction through the ring band, increasing the size of the anterior portion of the stomach pouch so that a gastroenteroanastomosis could be created at this point. Gastro-gastric sutures were placed to create a gastro-gastric plication around the band and hold it in position. The band tubing was exteriorized and connected to a special port, which was secured to the abdominal wall fascia. A jejunal loop was created about 200 cm from the ligament of Treitz and anastomosed to the gastric pouch by hand using Vicryl 2/0 sutures. Between November 2015 and February 2016, the study was performed on 10 patients. The average operating time for all cases was 75 min (range 63-87). There was no morbidity or mortality. No complications were observed, including band erosion and band infection. Operation costs were about $2000 lower with this method than with standard gastric bypass surgery. Postop the patients lost weight by 3-4 kg per month. Preliminary results show that laparoscopic band-separated one anastomosis gastric bypass have feasibility, safety, efficacy, and reduced operating costs.

The Spigelman classification stratifies cancer risk in familial adenomatous polyposis (FAP) patients with duodenal adenomatosis. High-resolution endoscopy (HRE) and narrow-band imaging (NBI) may identify lesions at high risk. To compare HRE and NBI for the detection of duodenal and gastric polyps and to characterize duodenal adenomas harboring advanced histology with HRE and NBI. Prospective, nonrandomized, comparative study. Retrospective image evaluation study. Tertiary-care center. Thirty-seven FAP patients undergoing surveillance upper endoscopies. HRE endoscopy was followed by NBI. The number of gastric polyps and Spigelman staging were compared. Duodenal polyp images were systematically reviewed in a learning and validation phase. Number of gastric and duodenal polyps detected by HRE and NBI and prevalence of specific endoscopic features in duodenal adenomas with advanced histology. NBI did not identify additional gastric polyps but detected more duodenal adenomas in 16 examinations, resulting in upgrades of the Spigelman stage in 2 cases (4.4%). Pictures of 168 duodenal adenomas (44% advanced histology) were assessed. In the learning phase, 3 endoscopic features were associated with advanced histology: white color, enlarged villi, and size ≥1 cm. Only size ≥1 cm was confirmed in the validation phase (odds ratio 3.0; 95% confidence interval, 1.2-7.4). Nonrandomized study, scant number of high-grade dysplasia adenomas. Inspection with NBI did not lead to a clinically relevant upgrade in the Spigelman classification and did not improve the detection of gastric polyps in comparison with HRE. The only endoscopic feature that predicted advanced histology of a duodenal adenoma was size ≥1 cm. Copyright © 2013 American Society for Gastrointestinal Endoscopy. Published by Mosby, Inc.

Acotiamide is a first-in-class prokinetic drug approved in Japan for the treatment of functional dyspepsia. Given that acotiamide enhances gastric motility in conscious dogs and rats, we assessed the in vitro effects of this drug on the contraction of guinea pig stomach strips and on acetylcholinesterase (AChE) activity in stomach homogenate following fundus removal. We also investigated the serotonin 5-HT4 receptor agonist mosapride, dopamine D2 receptor and AChE inhibitor itopride, and representative AChE inhibitor neostigmine. Acotiamide (0.3 and 1 μM) and itopride (1 and 3 μM) significantly enhanced the contraction of gastric body strips induced by electrical field stimulation (EFS), but mosapride (1 and 10 μM) did not. Acotiamide and itopride significantly enhanced the contraction of gastric body and antrum strips induced by acetylcholine (ACh), but not that induced by carbachol (CCh). Neostigmine also significantly enhanced the contraction of gastric body strips induced by ACh, but not that by CCh. In contrast, mosapride failed to enhance contractions induced by either ACh or CCh in gastric antrum strips. Acotiamide exerted mixed inhibition of AChE, and the percentage inhibition of acotiamide (100 μM) against AChE activity was markedly reduced after the reaction mixture was dialyzed. In contrast, itopride exerted noncompetitive inhibition on AChE activity. These results indicate that acotiamide enhances ACh-dependent contraction in gastric strips of guinea pigs via the inhibition of AChE activity, and that it exerts mixed and reversible inhibition of AChE derived from guinea pig stomach. © Georg Thieme Verlag KG Stuttgart · New York.

Splenic artery aneurysm is rare and its diagnosis is challenging due to the nonspecific nature of the clinical presentation. We report a case of a splenic artery aneurysm in which the patient presented with chronic dyspepsia and multiple episodes of minor intragastric bleeding. A 60-year-old, previously healthy Sri Lankan man presented with four episodes of hematemesis and severe dyspeptic symptoms over a period of 6 months. The results of two initial upper gastrointestinal endoscopies and an abdominal ultrasound scan were unremarkable. A third upper gastrointestinal endoscopy detected a pulsatile bulge at the posterior wall of the gastric antrum. A contrast-enhanced computed tomogram of his abdomen detected a splenic artery aneurysm measuring 3 × 3 × 2.5 cm. While awaiting routine surgery, he developed a torrential upper gastrointestinal bleeding and shock, leading to emergency laparotomy. Splenectomy and en bloc resection of the aneurysm with the posterior stomach wall were performed. Histology revealed evidence for a true aneurysm without overt, acute, or chronic inflammation of the surrounding gastric mucosa. He became completely asymptomatic 2 weeks after the surgery. Splenic artery aneurysms can result in recurrent upper gastrointestinal bleeding. The possibility of impending catastrophic bleeding should be remembered when managing patients with splenic artery aneurysms after a minor bleeding. Negative endoscopy and ultrasonography should require contrast-enhanced computed tomography to look for the cause of recurrent upper gastrointestinal bleeding.

A 25-year-old male presented with hematemesis, epigastric pain, and melena. He had dyspepsia with significant weight loss for 3 months period. On clinical examination, he was pale with no organomegaly or lymphadenopathy. The X-ray chest was normal, and ultrasound abdomen was normal. Upper GI endoscopy revealed nodularity and ulceration along proximal part of lesser curvature of the stomach. CT scan abdomen showed thickening of lesser curvature just below gastro-esophageal junction. The biopsies were negative for malignancy. Repeat upper GI endoscopy showed a nonhealing ulcer, on repeat well biopsies taken from the base of ulcer primary gastric tuberculosis was diagnosed. It showed many epithelioid cell granulomas and multinucleated giant cells with caseous necrosis on histology. Acid-fast bacilli on Zeil Neelsen staining and TB PCR were positive for Mycobacterium tuberculosis. He was put on four-drug anti-tuberculous treatment. On follow-up, the patient gradually improved and regained weight. Repeat upper GI endoscopy done after 8 weeks showed healing of the ulcer with decrease in nodularity.

We report the clinical observation of a 58-year old patient who presented with upper abdominal pain and a small ecchymosis located in the umbilical area. Personal history of the patient revealed ischemic heart disease and chronic atrial fibrillation. He was under treatment with oral anticoagulants (coumarins). The clinical data and especially the imaging investigations led to a diagnosis of gastric wall hematoma, possibly occurring post-traumatically in a patient under anticoagulant treatment. A conservative therapeutic approach was adopted and ultrasound surveillance. After 6 months the gastric parietal collection manifested complete resorption, spontaneously. In relation to the case presentation, we also discuss some issues on the frequency, diagnosis and therapeutic attitude in this rare complication of anticoagulant therapy.

Helicobacter pylori infection, non-steroidal anti-inflammatory drugs and peptic ulcer are considered as the major factors for upper gastrointestinal system bleeding. The objective of the study was to determine the sociodemographic and etiologic factors, management and outcome of patients with non-variceal upper gastrointestinal system bleeding in Turkey. Patients who admitted to hospitals with upper gastrointestinal system bleeding and in whom upper gastrointestinal endoscopy was performed were enrolled in this retrospective study. The detailed data of medical history, comorbid diseases, medications, admission to intensive care units, Helicobacter pylori infection, blood transfusion, upper gastrointestinal endoscopy, and treatment outcome were documented. The most frequent causes of bleeding (%) were duodenal ulcer (49.4), gastric ulcer (22.8), erosion (9.6), and cancer (2.2) among 1,711 lesions in endoscopic appearances of 1,339 patients from six centers. Seven hundred and four patients were evaluated for Helicobacter pylori infection and the test was positive in 45.6% of those patients. Comorbid diseases were present in 59.2% of the patients. The percentage of patients using acetylsalicylic acid and/or other non-steroidal anti-inflammatory drug was 54.3%. Bleeding was stopped with medical therapy in 66.9%. Only 3.7% of the patients underwent emergency surgery, and a 1.1% mortality rate was determined. Patients with upper gastrointestinal system bleeding were significantly older, more likely to be male, and more likely to use non-steroidal anti-inflammatory drugs. Though most of the patients were using gastro-protective agents, duodenal and gastric ulcers were the contributing factors in more than 70% of the upper gastrointestinal bleeding. The extensive use of non-steroidal anti-inflammatory drug is a hazardous health issue considering the use of these drugs in half of the patients.

Although the Vienna Classification recommends endoscopic resection for gastric high-grade dysplasia (HGD), many resected lesions are diagnosed as gastric cancer after endoscopic resection. This study aims to evaluate the clinical outcomes of gastric HGD identified by endoscopic forceps biopsy (EFB) after endoscopic submucosal dissection (ESD) and factors associated with discrepant results. From December 2008 to July 2015, a total of 427 lesions diagnosed as initial HGD by EFB were enrolled. The rate of early gastric cancer (EGC) and factors predicting diagnosis upgrade were analyzed retrospectively. Tumors ranged between 2 and 65 mm in size (median 12.59). En bloc and complete resection rates were 97.4 and 95.3%, respectively. The diagnostic discrepancy rate was 76.3%. Upgrade and downgrade rates of pathological diagnoses were 66.5 and 9.8%, respectively. Central depression (OR 4.151), nodular surface (OR 5.582), surface redness (OR 2.926), lesion location (upper third of the stomach) (OR 3.894), and tumor size ≥10 mm (OR 2.287) were significantly associated with EGC. Nodular surface (OR 2.746), submucosal fibrosis (OR 3.958), lesion location (upper third of the stomach) (OR 6.652), and tumor size ≥10 mm (OR 4.935) significantly predicted invasive submucosal cancer. Central depression, nodular surface, surface redness, lesion location, large tumor size, and submucosal fibrosis were associated with EGC or submucosal cancer. Caution must be used in treating lesions with these features with ESD.

It is often difficult to differentiate gastric mucosa-associated lymphoid tissue (MALT) lymphoma from Helicobacter pylori-associated follicular gastritis, and thus, it becomes unclear how to manage these diseases. This study aimed to explore the management strategy for and the long-term outcomes of suspicious gastric MALT lymphoma detected by forceps biopsy during screening upper endoscopy. Between October 2003 and May 2013, consecutive subjects who were diagnosed with suspicious gastric MALT lymphomas by screening endoscopy in a health checkup program in Korea were retrospectively enrolled. Suspicious MALT lymphoma was defined as a Wotherspoon score of 3 or 4 upon pathological evaluation of the biopsy specimen. Of 105,164 subjects who underwent screening endoscopies, 49 patients with suspicious MALT lymphomas who underwent subsequent endoscopy were enrolled. Eight patients received a subsequent endoscopy without H. pylori eradication (subsequent endoscopy only group), and 41 patients received H. pylori eradication first followed by endoscopy (eradication first group). MALT lymphoma development was significantly lower in the eradication first group (2/41, 4.9%) than in the subsequent endoscopy only group (3/8, 37.5%, P = 0.026). Notably, among 35 patients with successful H. pylori eradication, there was only one MALT lymphoma patient (2.9%) in whom complete remission was achieved, and there was no recurrence during a median 45 months of endoscopic follow-up. H. pylori eradication with subsequent endoscopy would be a practical management option for suspicious MALT lymphoma detected in a forceps biopsy specimen obtained during screening upper endoscopy.

The authors investigated the relationship between hot tea, iced tea, coffee and carbonated soft drinks consumption and upper gastrointestinal tract cancers risk in the NIH-AARP Study. During 2,584,953 person-years of follow-up on 481,563 subjects, 392 oral cavity, 178 pharynx, 307 larynx, 231 gastric cardia, 224 gastric non-cardia cancer, 123 Oesophageal Squamous Cell Carcinoma (ESCC) and 305 Oesophageal Adenocarcinoma (EADC) cases were accrued. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were calculated by multivariate-adjusted Cox regression. Compared to non-drinking, the hazard ratio for hot tea intake of > or =1 cup/day was 0.37 (95% CI: 0.20, 0.70) for pharyngeal cancer. The authors also observed a significant association between coffee drinking and risk of gastric cardia cancer (compared to <1 cup/day, the hazard ratio for drinking >3 cups/day was 1.57 (95% CI: 1.03, 2.39)), and an inverse association between coffee drinking and EADC for the cases occurring in the last 3 years of follow-up (compared to <1 cup/day, the hazard ratio for drinking >3 cups/day was 0.54 (95% CI: 0.31, 0.92)), but no association in earlier follow-up. In summary, hot tea intake was inversely associated with pharyngeal cancer, and coffee was directly associated with gastric cardia cancer, but was inversely associated with EADC during some follow-up periods.

Effectiveness of splenectomy for advanced gastric cancers occupying the upper and/or the middle third of the stomach is still in debate. The aim of the present study is to elucidate the impact of splenectomy on patient survival by investigating the pathological characteristics and prognostic significance of splenic hilar lymph node metastasis. Clinicopathologic and prognostic data of 265 patients with gastric cancer in the upper and/or the middle third of the stomach who underwent the operation of en bloc resection of primary cancer and D2/D3 lymphadenectomy combined with splenectomy were retrospectively reviewed. Multivariate analysis revealed pT category, pN category, and distant lymph node metastasis independently correlated with the presence of splenic hilar lymph node metastasis. Prognoses of patients with positive splenic hilar lymph nodes were significantly poorer than that of patients with negative splenic hilar lymph nodes for the entire study population and for those who underwent R0 resection, but not for those who underwent R1-2 resection. There was no significant difference in survival between patients who underwent R0 resection with positive splenic hilar lymph nodes and those who underwent R1-2 resection. Splenic hilar lymph node metastasis was one of independent indicators predicting worse prognosis and the presence of distant metastasis after surgery. Subset analysis according to the TNM stage revealed there were significant differences in survival between patients with and without splenic hilar lymph node metastasis. Splenic hilar lymph node metastasis should be considered as one of incurable factors. Consequently, the efficiency of splenectomy aiming at prolonging survival for patients with high risk of splenic hilar lymph nodes metastasis should be questioned, although resection of invasive organs form gastric cancers has been recommended if R0 surgery could be achieved.

Gastric metastases from renal cell carcinoma (RCC) are rare with few cases described in the literature. We report the history of a 77-year-old male patient who underwent a right radical nephrectomy because of RCC. Two years after the diagnosis, he presented with abdominal pain and evidence of upper gastrointestinal bleeding. Esophagogastroduodenoscopy revealed a 3 cm, ulcerated, pedunculated polypoid mass in the stomach that was removed with a diathermic snare. Histology with immunohistochemistry confirmed the diagnosis of metastatic RCC. Three months of follow-up revealed no further episode of rebleeding. We identified (using the PubMed database) 44 cases of gastric metastasis of RCC in the literature; the majority were male patients, with mean age at presentation of 67.2 years and average time from nephrectomy to presentation of gastric metastases of 6.9 years. Our results suggest that endoscopy may have an important role in the treatment of these patients for controlling the complications and/or improving mean survival time. Gastric metastases of RCC are rare but should be considered even many years after diagnosis and treatment of RCC, particularly in patients with gastrointestinal symptoms.

Background Roux-en-Y gastric bypass increases circulating bile acid concentrations, known mediators of postprandial suppression of markers of bone resorption. Long-term data, however, indicate that Roux-en-Y gastric bypass confers an increased risk of bone loss on recipients. Methods Thirty-six obese individuals, median age 44 (26-64) with median body mass index at baseline of 42.5 (40.4-46) were studied before and 15 months after Roux-en-Y gastric bypass. After an overnight fast, patients received a 400 kcal mixed meal. Blood samples were collected premeal then at 30-min periods for 120 min. Pre and postmeal samples were analysed for total bile acids, parathyroid hormone and C-terminal telopeptide. Results Body weight loss post Roux-en-Y gastric bypass was associated with a median 4.9-fold increase in peak postprandial total bile acid concentration, and a median 2.4-fold increase in cumulative food evoked bile acid response. Median fasting parathyroid hormone, postprandial reduction in parathyroid hormone and total parathyroid hormone release over 120 min remained unchanged after surgery. After surgery, median fasting C-terminal telopeptide increased 2.3-fold, peak postprandial concentrations increased 3.8-fold and total release was increased 1.9-fold. Conclusions Fasting and postprandial total bile acids and C-terminal telopeptide are increased above reference range after Roux-en-Y gastric bypass. These changes occur in spite of improved vitamin D status with supplementation. These results suggest that post-Roux-en-Y gastric bypass increases in total bile acids do not effectively oppose an ongoing resorptive signal operative along the gut-bone axis. Serial measurement of C-terminal telopeptide may be of value as a risk marker for long-term skeletal pathology in patients post Roux-en-Y gastric bypass.

Massive weight loss following bariatric surgery leads to excess skin with functional and aesthetic impairments. Surplus skin can then contribute to problems with additional weight loss or gain. The aims of the current study were to evaluate the frequency of massive soft tissue development in gastric bypass patients, to determine whether males and females experience similar post-bypass body changes, and to learn about the expectations and impairments related to body contouring surgery. A questionnaire addressing information on the satisfaction of body image, quality of life, and expectation of body contouring surgery following massive weight loss was mailed to 425 patients who had undergone gastric bypass surgery between 2003 and 2009. Of these 425 individuals, 252 (59%) patients completed the survey. Ninety percent of women and 88% of men surveyed rated their appearance following massive weight loss as satisfactory, good, or very good. However, 96% of all patients developed surplus skin, which caused intertriginous dermatitis and itching. In addition, patients reported problems with physical activity (playing sports) and finding clothing that fit appropriately. Moreover, 75% of female and 68% of male patients reported desiring body contouring surgery. The most important expectation of body contouring surgery was improved appearance, followed by improved self-confidence and quality of life. Surplus skin resulting from gastric bypass surgery is a common issue that causes functional and aesthetic impairments in patients. Consequently, this increases the desire for body contouring surgery with high expectations for the aesthetic outcome as well as improved life satisfaction.

[Surgical treatment for morbid obesity].

Obesity has become a serious public health problem in Mexico and at present time and the best treatment for morbid obesity is surgery. Recently, laparoscopic techniques have become available for treatment of this disease. Surgery is indicated in patients with body mass index (BMI) >35 kg/m2, and with comorbidity. Restrictive procedures such as adjustable gastric banding and vertical banded gastroplasty have less incidence of postoperative complications; however efficacy in terms of weight loss is not as good as in malabsorptive or mixed procedures. Patients who undergo these malabsorptive or mixed procedures (gastric bypass, biliopancreatic diversion) are at higher risk for postoperative complication. To date, gastric bypass is considered the care standard for treatment of morbid obesity; it confers an approximately 70% of body-weight-loss excess, with an acceptable rate of complications.

Helicobacter pylori is a known contributor to ulcerogenesis and nonvariceal acute upper gastrointestinal hemorrhage. Its incidence in operatively managed patients with upper gastrointestinal hemorrhage is ill defined. Patients undergoing surgery for upper gastrointestinal hemorrhage secondary to gastroduodenal ulceration between 1993 and 1998 at the University of Tennessee were retrospectively reviewed. Factors examined included age, nonsteroidal drug use, endoscopic intervention, urgency of operation, and H. pylori status confirmed by histologic examination. Forty-two patients had surgery with three excluded because of a lack of histologic evaluation. The site of bleeding was gastric in 23 and duodenal in 14. H. pylori infection was present in nine (39.1%) gastric and 11 (68.7%) duodenal ulcers. The incidence of H. pylori infection was reduced in those over 60 years of age (28.6%). Endoscopy was performed in all patients, but only two had biopsies for assessment of H. pylori. Operative morbidity was 17.9% and mortality was 5.1%. No patient had rebleeding following surgery. The incidence of H. pylori in this population is less than that reported in uncomplicated ulcer disease. Those older than 60 tended to be H. pylori negative. Endoscopic assessment for H. pylori was infrequent. Traditional indications for surgical intervention in ulcer hemorrhage should not be altered based on H. pylori status.

The effects of administering a single dose of (200 mg to 50 mg/kg body weight) aspirin or an equimolar mixture of aspirin (200 mg/kg body wt) with sodium bicarbonate on the fine structure of the rat gastric mucosa were investigated in order to establish the role of particles of the drug in the development of gastric damage. The sequence of cellular events involved in the development of a lesion and the influence of short-term starvation were also investigated. Aspirin-bicarbonate solutions produced much less damage in starved rats than aspirin suspensions given at low (50 mg/kg body weight) or high therapeutic doses (200 mg/kg body weight). Also, when non-starved rats were given 200 mg/kg aspirin, only slight damage was observed. The presence of particles of the drug in intimate contact with the mucosa is thus important in the development of gastric damage. A sequence of events with time involving direct physical exfoliation of mucosal cells and selective structural damage to parietal cells followed by structural damage indicative of a disturbance to oxidative and biosynthetic functions in cells near the developing erosion was observed. The implications of these results on the development of aspirin-induced lesions are discussed. Images Fig 3a Fig 3b Fig 1a Fig 1b Fig 1c Fig 2a Fig 2b Fig 4 Fig 5 PMID:1158188

We examined the effects of surgical and gastric transmitter implantation techniques on the growth, general physiology and behavior of 230 subyearling chinook salmon (Oncorhynchus tshawytscha, Walbaum) (100 mm-154 mm fork length). The transmitter weighed 1.3 g in air (0.9 g in water) and comprised, on average, 6% of the body weight of the fish (in air). Individuals were randomly assigned to an experimental group (control, surgical or gastric) and a sampling period (day 5 or day 21). Relative growth rate was expressed as% body weight gained/day. General condition was assessed by necropsy. Physiological response variables included hematocrit, leucocrit and plasma protein concentration. The mean relative growth rates of control, surgical and gastric fish were not significantly different at day 5. By day 21, the gastric group had a significantly lower relative growth rate (1.3%) as compared to the surgical group (1.8%) and the control group (1.9%) (P = 0.0001). Mean hematocrit values were significantly lower in the surgical (41.8%) and gastric (42.2%) groups as compared to controls (47.3%) at day 5 (P = 0.01), but all were within normal range for salmonids. No significant differences in hematocrit values were detected at day 21. Leucocrit values for all groups were ??? 1% in 99% of the fish. Both tagged groups had significantly lower mean plasma protein levels as compared to controls at day 5 (P = 0.001) and day 21 (P = 0.0001). At day 21 the gastric group (64.4 g 100 m1-1) had significantly lower mean plasma protein levels than the surgical group (68.8 g 100 ml-1) (P = 0.0001). Necropsies showed decreasing condition of gastrically tagged fish over time, and increasing condition of surgical fish. Paired releases of surgically and gastrically implanted yearling chinook salmon in the lower Columbia River in spring, 1996 revealed few significant differences in migration behavior through two reservoirs. We conclude that gastrically implanted fish show decreased growth and condition over a 21 d period. We recommend a surgical implantation method for long-term studies of juvenile salmonids, however, gastric implantation may be suitable for short-term studies.

Bulimia nervosa remains a common eating disorder in young women. Little is known about upper gastrointestinal symptoms or gastric motility in patients with bulimia nervosa. The aim of this study was to measure gastric myoelectrical activity and hunger/satiety and stomach emptiness/fullness before and after a non-nutrient water load and solid-phase gastric emptying in hospitalized patients with bulimia nervosa (n = 12) and in healthy women (n = 13). Gastric myoelectrical activity was measured by means of cutaneous electrodes; visual analogue scales were used to measure perceptions of hunger/satiety and stomach emptiness/fullness. Before and after a standard water load the bulimia patients reported significantly greater stomach fullness and satiety compared with control subjects (P < 0.01). The percentage of gastric myoelectrical power in the normal 3 cpm range was significantly less in bulimics compared with controls. Power in the 1-2 cpm bradygastria range was significantly greater in bulimia patients before and after the water load compared with the control subjects (P < 0.05). Solid-phase gastric emptying studies using radio-isotope-labelled scrambled eggs showed the lag phase was shortened in the bulimic patients (16 +/- 4 min vs 31 +/- 4 min in controls, P < 0.01), but the percentage of meal emptied at 2 h was similar to control values. bulimia patients had exaggerated perceptions of stomach fullness and satiety in response to water; and abnormal gastric myoelectrical activity and accelerated lag phase of gastric emptying were objective stomach abnormalities detected in hospitalized patients with bulimia nervosa.

Background Physical or psychological stress causes functional disorders in the upper gastrointestinal tract. This study aims to elucidate the ameliorating effect of exogenous acylated ghrelin or rikkunshito, a Kampo medicine which acts as a ghrelin enhancer, on gastric dysfunction during acute restraint stress in mice. Methods Fasted and postprandial motor function of the gastric antrum was wirelessly measured using a strain gauge force transducer and solid gastric emptying was detected in mice exposed to restraint stress. Plasma corticosterone and ghrelin levels were also measured. To clarify the role of ghrelin on gastrointestinal dysfunction in mice exposed to stress, exogenous acylated ghrelin or rikkunshito was administered, then the mice were subjected to restraint stress. Key Results Mice exposed to restraint stress for 60 min exhibited delayed gastric emptying and increased plasma corticosterone levels. Gastric motility was decreased in mice exposed to restraint stress in both fasting and postprandial states. Restraint stress did not cause any change in plasma acylated ghrelin levels, but it significantly increased the plasma des-acyl ghrelin levels. Administration of acylated ghrelin or rikkunshito improved the restraint stress-induced delayed gastric emptying and decreased antral motility. Ameliorating effects of rikkunshito on stress-induced gastric dysfunction were abolished by simultaneous administration of a ghrelin receptor antagonist. Conclusions & Inferences Plasma acylated/des-acyl ghrelin imbalance was observed in acute restraint stress. Supplementation of exogenous acylated ghrelin or enhancement of endogenous ghrelin signaling may be useful in the treatment of decreased gastric function caused by stress. PMID:24684160

Reflux of gastroduodenal contents and delayed gastric emptying are the most common and serious problems after esophagectomy with gastric reconstruction. However, attempts to reduce the above symptoms, surgically as well as non-surgically, had no or limited effect. To address this issue, we performed retrosternal gastric reconstruction with duodenal diversion plus Roux-en-Y anastomosis (RY) in eight patients with thoracic esophageal cancer and compared the outcomes with control patients who underwent standard reconstruction. The procedure is simple, safe, and not associated with any postoperative complications. The pancreatic amylase concentrations in the gastric juice samples on postoperative day 2 were slightly lower in the non-RY group than in the RY group (1884 ± 2152 vs. 25,790 ± 23,542IU/mL, respectively, P= 0.07). Postoperative endoscopic examination showed neither reflux esophagitis nor residual gastric content in the RY group. Quality of life assessed by the Dysfunction After Upper Gastrointestinal Surgery-32 questionnaire postoperatively was significantly better in the RY group than in the non-RY group for 'decreased physical activity,''symptoms of reflux,''nausea and vomiting,' and 'pain.' The results of this pilot study suggest that gastric reconstruction with duodenal diversion plus RY seems effective in improving both the reflux and delayed gastric emptying. The benefits of this procedure need to be further assessed in a large-scale, randomized controlled trial. © 2011 Copyright the Authors.

Primary gastric lymphoma is defined as the malignant lymphoproliferative disease with initial symptoms located in the stomach, or tumor mass located in the stomach. This paper aims to present the macroscopic, histopathological and immunohistochemical aspects encountered in a group of patients with primary gastric lymphoma, diagnosed between 2005 and 2010 in the Hematology Clinic of Craiova and the Hematology Clinic of "Fundeni" Institute in Bucharest. This study was performed on a group of 65 patients diagnosed with primary gastric lymphoma. The positive diagnosis in primary gastric lymphoma is established by the histopathological and immunohistochemical analysis of gastric biopsies, taken during the upper gastrointestinal endoscopy, or of gastric resection samples. We used the monoclonal antibodies CD20, CD10, CD5, k light chain, PCNA (proliferating cell nuclear antigen) and Ki67. The average age of the patients enrolled in the study was 52.55 years. The most common macroscopic feature encountered was the mixed ulcerative-vegetative one. We found two histological types, represented by diffuse large B-cell lymphoma (with or without MALT component), and marginal zone lymphoma (MALT type). Both the MALT type lymphoma and the diffuse large B-cell lymphoma revealed B-cell phenotype. A correct diagnosis is very important in terms of therapeutic approach. The characteristics of the group of patients were: a higher number of the aggressive histological type; an excessive use of gastric resection; none of the cases was a T-lymphoproliferation.

Metastases to the gastrointestinal tract rarely occur in breast cancer except in invasive lobular carcinoma. The present study reports a rare case of metastatic gastric cancer from invasive ductal carcinoma (IDC) of the breast mimicking primary gastric linitis plastica. A 51-year-old premenopausal female, who had a history of partial mastectomy for right breast cancer at the age of 40, was referred to Toyama City Hospital (Toyoma, Japan) for an endoscopic diagnosis of gastric linitis plastica. Abdominal computed tomography (CT) revealed left hydronephrosis, while peritoneal metastasis and malignant ascites were not detected. Chest CT detected a left lung tumor, which had invaded the left upper bronchus. Biopsy specimens were obtained and the histopathological findings on both the gastric tumor and lung tumor demonstrated poorly differentiated adenocarcinoma, whereas the histology of the original breast cancer was IDC with a solid-tubular type. Immunohistochemistry revealed that the biopsied specimens of the gastric and lung tumors were positive for estrogen receptor (ER), progesterone receptor (PgR) and negative for human epithelial growth factor receptor-2 (HER2). These molecular characteristics indicated the case was metastatic gastric carcinoma from the breast cancer with lung metastasis, since the statuses of ER, PgR and HER2 were concordant with those of the original breast cancer. However, the possibility of primary gastric cancer could not be completely ruled out. Therefore, a total gastrectomy was performed for the purpose of both diagnosis and treatment. Pathological examination of the resected specimen provided a definite diagnosis of multiple metastatic gastric carcinomas from the breast. To the best of our knowledge, metastatic gastric cancer derived from the breast presenting as linitis plastica 11 years following the surgical removal of IDC has not been described previously.

Abdominal pain is a frequent occurrence among the pediatric population and can be a diagnostic challenge. Trichobezoar is a differential diagnosis that is often neglected. Different from previously reported cases, we present a 3-year-old girl with sickle cell disease with complaints of acute abdominal pain, suspecting sickle cell splenic sequestration. The child presented to the emergency department with sharp epigastric pain and an associated palpable upper abdominal mass. This case illustrates a large obstructing gastric trichobezoar and summarizes both the diagnostic modalities and treatment.

In Japan, distal gastrectomy is the most common operation performed to treat gastric cancer. However, this procedure often leads to postoperative problems such as weight loss. We assessed the changes of nutritional status early after operation and the associations of the postoperative body weight (as a percentage of the preoperative weight) and background factors in patients who underwent distal gastrectomy. We measured the changes of nutritional indices (mean body weight, TSF, AMC and Alb) and nutrition intake on the day before operation (before operation), before postoperative resumption of oral intake (before oral intake), and on the fifth day of a soft rice porridge diet (after soft rice). Background factors included gender, age, preoperative BMI and preoperative exercise. Mean body weight, TSF, and AMC significantly decreased from before operation, to the day before oral intake and to the day after soft rice. The postoperative body weight was not associated with the gender, age, or preoperative BMI. The frequency of regular preoperative exercise was associated with the postoperative body weight. The total daily calorie intake was 1,664 kcal (before operation), 398 kcal (before oral intake), and 949 kcal (after soft rice). To conclude, nutritional status changes significantly after distal gastrectomy. Early nutrition intervention may be needed in patients who undergo distal gastrectomy for gastric cancer.

One anastomosis gastric bypass (OAGB) demonstrated results similar to traditional Roux-en-Y procedures [1-3], in terms of weight loss and resolution of obesity-related comorbidities. The main controversy regarding OAGB is the concern for an association between biliary alkaline gastritis and esophageal or gastric cancer raised by some studies [4]. We present the case of a 51-year-old woman with a BMI of 41 kg/m2 who underwent a laparoscopic OAGB in 2014. One year later, she consulted for recurrent heartburns. An upper GI endoscopy showed pouchitis and bile reflux in the esophagus. Medical treatment of gastroesophageal reflux disease was ineffective. We decided to convert the OAGB to a Roux-en-Y gastric bypass (RYGB). In this video, we show how to revise an OAGB to treat chronic bile reflux, by converting the procedure to a standard RYGB. The intervention starts by restoring the normal anatomy of the small bowel, with the resection of the gastrojejunal anastomosis, which was located at 250-cm du Treitz's ligament. Then, the gastric pouch is created. A standard Roux-en-Y gastric bypass is performed. The resection of the gastrojejunal anastomosis allows fashioning the Roux-en-Y limb with the classical measures. This technique allows a conversion to a standard RYGB and is effective in treating the biliary reflux.

Spontaneous gastric perforation is a rare complication of gastric lymphoma that is potentially life threatening since it can progress to sepsis and multi-organ failure. Morbidity also increases due to prolonged hospitalization and delay in initiating chemotherapy. Therefore prompt diagnosis and appropriate treatment is critical to improve prognosis. A 64-year-old man presented to the emergency department with severe abdominal pain. Chest X-ray showed free air below the right diaphragm. Abdominal CT scan also demonstrated free air in the peritoneal cavity with large wall defect in the lesser curvature of gastric lower body. Therefore, the patient underwent emergency operation and primary closure was done. Pathologic specimen obtained during surgery was compatible to diffuse large B cell lymphoma. Fifteen days after primary closure, the patient received subtotal gastrectomy and chemotherapy was initiated after recovery. Patient is currently being followed-up at outpatient department without any particular complications. Herein, we report a rare case of gastric lymphoma that initially presented as peritonitis because of spontaneous gastric perforation.

In up to 4% of laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures, anastomotic leaks occur. Early detection of gastrointestinal leakage is important for successful treatment. Consequently, many centers advocate routine postoperative upper gastrointestinal (UGI) series. The aim of this study was to determine the utility of this practice after LRYGB. Eight hundred four consecutive patients undergoing LRYGB from June 2000 to April 2010 were analyzed prospectively. The first 382 patients received routine UGI series between the third and fifth postoperative days (group A). Thereafter, the test was only performed when clinical findings (tachycardia, fever, and drainage content) were suspicious for a leak of the gastrointestinal anastomosis (group B; n = 422). Overall, nine of 804 (1.1%) patients suffered from leaks at the gastroenterostomy. In group A, four of 382 (1%) patients had a leak, but only two were detected by the routine UGI series. This corresponds to a sensitivity of 50%. In group B, the sensitivity was higher with 80%. Specificities were comparable with 97% and 91%, respectively. Routine UGI series cost only 1.6% of the overall costs of a non-complicated gastric bypass procedure. With this leak rate and sensitivity, US $86,800 would have to be spent on 200 routine UGI series to find one leak which is not justified. This study shows that routine UGI series have a low sensitivity for the detection of anastomotic leaks after LRYGB. In most cases, the diagnosis is initiated by clinical findings. Therefore, routine upper gastrointestinal series are of limited value for the diagnosis of a leak.

Horses lose considerably more electrolytes through sweating during prolonged exercise than can be readily replaced through feeds. The present study tested an oral electrolyte supplement (ES) designed to replace sweat electrolyte losses. We measured gastric emptying of 3 litres of ES (using gamma imaging of (99)Tc-sulfide colloid), the absorption of Na(+) and K(+) from the gastrointestinal tract using (24)Na(+) and (42)K(+), and the distribution of these ions in the body by measuring radioactivity within plasma and sweat during exercise. Three litres of ES emptied from the stomach as fast as water, with a half-time of 47 min, and appeared in plasma by 10 min after administration (n = 4 horses). Peak values of plasma (24)Na(+) and (42)K(+) radioactivity occurred at 20-40 min, and a more rapid disappearance of K(+) radioactivity from plasma was indicative of movement of K(+) into cells (n = 3 horses). In a randomized crossover experiment (n = 4 horses), 1 h after administration of placebo (water), 1 or 3 litres of ES containing (24)Na(+), horses exercised on a treadmill at 30% of peak oxygen uptake until voluntary fatigue. The (24)Na(+) appeared in sweat at 10 min of exercise, and when horses received 3 litres of ES the duration to voluntary fatigue was increased in all horses by 33 ± 10%. It is concluded that an oral ES designed to replace sweat ion losses was rapidly emptied from the gastrointestinal tract, rapidly absorbed in the upper intestinal tract and rapidly distributed within the body. The ES clearly served as a reservoir to replace sweat ion losses during exercise, and administration of ES prior to exercise resulted in increased duration of submaximal exercise.

Itopride, a dopamine D2 antagonist and acetylcholinesterase inhibitor, significantly improved symptoms in patients with functional dyspepsia in one phase II randomized trial. However, the mechanisms by which itopride may improve symptoms are unknown. We aimed to compare the effects of two doses of itopride and placebo on gastric volumes, gastric emptying, small bowel transit and satiation in female and male healthy volunteers. Randomized, double-blind, placebo-controlled study evaluated gastric function before and after 7 days of itopride 100 mg (n = 16) or 200 mg (n = 15) or placebo (n = 15) t.i.d. Validated methods were used to study gastric accommodation (single photon emission computed tomography), gastric emptying and orocecal transit and satiation postnutrient challenge. The three arms were comparable with regard to age, gender and body mass index. There were no statistically significant effects of itopride on gastric emptying, orocecal transit, fasting gastric volume, maximum tolerated volume or aggregate symptom score with nutrient drink challenge. Postprandial (PP) change in gastric volume differed in the three groups (P = 0.019): 625[+/-28 (SEM)], 555(+/-26) and 512(+/-33) in placebo, itopride 100 and 200 mg groups, respectively. In healthy subjects, itopride reduced total PP gastric volume without accelerating gastric emptying or significantly altering gastric motor and sensory function in healthy individuals.

Introduction Vertical-banded gastroplasty, a technique that is commonly performed in the treatment of morbid obesity, represents a nonadjustable restrictive procedure which reduces the volume of the upper stomach by a vertical stapler line. In addition, a textile or silicone band restricts food passage through the stomach. Case presentation A 71-year-old woman presented with a severe gastric stenosis 11 years after vertical gastroplasty. We describe a side-to-side gastrogastrostomy as a safe surgical procedure to restore the physiological gastric passage after failed vertical-banded gastroplasty. Conclusion Occasionally, restrictive procedures for morbid obesity cannot be converted into an alternative bariatric procedure to maintain weight control. This report demonstrates that a side-to-side gastrogastrostomy is a feasible and safe procedure. PMID:18513454

Neurologically impaired children (NIC) have a high risk of recurrence of gastroesophageal reflux (GER) following fundoplication. A postpyloric feeding tube may be useful when gastric emptying disorders occur; however, dislocation and difficulty in feeding management often require more aggressive procedures. Total esophagogastric dissociation (Bianchi's TEGD) is an alternative to the classic fundoplication procedure, whereas laparoscopic gastric bypass is a frequently performed procedure in morbid obesity, improving gastric outlet. The aim of this paper is to present a preliminary experience on the laparoscopic Roux-en-Y gastrojejunal bypass, associated with Nissen fundoplication and gastrostomy, to treat and prevent GER in NIC with gastric emptying disorders. Eight neurologically impaired children underwent surgical treatment because of feeding problems and pulmonary complications. The procedure included: 1) hiatoplasty, 2) Nissen fundoplication, 3) 20-cm Roux-en-Y gastrojejunal anastomosis and jejuno-jejunal anastomosis, and 4) gastrostomy. All cases were fed on postoperative day 3 without any intraoperative complications. One case developed an obstruction of the distal anastomosis due to adhesion and needed reoperation. Outcome was clinically evaluated with serial upper gastrointestinal contrast studies and endoscopies. Laparoscopic proximal Roux-en-Y gastrojejunal diversion, without gastric resection, is a safe, feasible procedure that improves gastric emptying and reduces the risk of GER recurrence. Yet, long-term results still have to be evaluated.

Extramedullary plasmacytoma is a plasma cell neoplasm that presents as a solitary lesion in soft tissue. Most extramedullary plasmacytomas involve the nasopharynx or upper respiratory tract. Primary plasmacytoma of the stomach is extremely rare. A 78-year-old Korean woman presented with epigastric pain for 3 months. She had a history of an intractable gastric ulcer despite repeated endoscopic biopsies and appropriate medical therapy for the ulcer. She underwent another endoscopy and a biopsy was performed for multiple large and deep specimens. Ultimately, primary gastric plasmacytoma was confirmed. However, she and her attendant refused standard local radiotherapy or surgical resection. She came to our emergency room 3 months later with hematemesis due to a large gastric ulcer, despite management with medication for over 3 months at a local clinic. We again recommended local radiation or surgical resection. However, as she was willing to undergo only medical therapy, she was prescribed high-dose dexamethasone. Surprisingly, her ulcer completely regressed and remission was maintained for over 1 year. We report successful treatment of a rare primary gastric plasmacytoma mimicking intractable ulcer by using high-dose dexamethasone. To the best of our knowledge, this is the first reported case successfully treated with only high-dose dexamethasone.

AIM: To determine clinical characteristics and treatment outcome of gastric lymphoma after chemotherapy and immuno-chemotherapy. METHODS: Thirty four patients with primary gastric mucosa associated lymphoid tissue (MALT) lymphoma (Ann Arbor stages I to IV) were enrolled. All had upper gastric endoscopy, abdominal ultrasonography, CT and H pylori status assessment (histology and serology). After anti-H pylori treatment and initial chemotherapy, patients were re-examined every 4 mo. RESULTS: Histological regression of the lymphoma was complete in 22/34 (64.7%) and partial in 9 (26.5%) patients. Median follow up time for these 31 responders was 60 mo (range 48-120). No regression was noted in 3 patients. Among the 25 (73.5%) H pylori positive patients, the eradication rate was 100%. CONCLUSION: Using univariate analysis, predictive factors for overall survival were international prognostic index (IPI) score, hemoglobin level, erythrocyte sedimentation rate (ESR), and platelet numbers (P < 0.005). In addition to this, Cox proportion hazard model differentiate IPI score, ESR, and platelets as predictors of survival. PMID:18416467

The present report describes a rare case of a tumor composed of early gastric cancer and a duodenal neuroendocrine tumor (NET). A 78-year-old woman underwent esophagogastroduodenoscopy at a local institution for screening of the upper gastrointestinal tract which revealed a protruded tumor through the pyloric ring from the pyloric antrum. The tumor was too large to treat at the facility; consequently, she was referred to our hospital for further management. Esophagogastroduodenoscopy with tumor biopsy of the lesion revealed the diagnosis of early gastric cancer. Endoscopic submucosal dissection was performed with sufficient free margins in both vertical and horizontal directions. Histopathological findings showed NET confined to the submucosal layer and covered by well-differentiated adenocarcinoma. Immunohistochemical stainings showed that the two lesions existed continuously. While the possibility of a collision cancer was considered, it was suggested that the two lesions existed continuously. Finally, the tumor was diagnosed as gastric cancer composed of duodenal NET G1, with a lymphatic invasion of NET component. PMID:27688667

Diagnosis and management of pernicious anemia.

Annibale, Bruno; Lahner, Edith; Fave, Gianfranco Delle

2011-12-01

Pernicious anemia is a macrocytic anemia due to cobalamin deficiency, which is the result of intrinsic factor deficiency. Pernicious anemia is associated with atrophic body gastritis, whose diagnostic criteria are based on the histologic evidence of gastric body atrophy associated with hypochlorhydria. Serological markers suggesting the presence of oxyntic mucosa damage are increased levels of fasting gastrin and decreased levels of Pepsinogen I. Without the now obsolete Schilling's test, intrinsic factor deficiency may not be proven, and gastric intrinsic factor output after pentagastric stimulation has been proposed. Intrinsic factor autoantibodies are useful surrogate markers of pernicious anemia. The management of patients with pernicious anemia should focus on the life-long replacement treatment with cobalamin and the monitoring to early diagnose an eventual onset of iron deficiency. Moreover, these patients should be advised about possible gastrointestinal long-term consequences, such as gastric cancer and carcinoids.

To investigate the expression of tumor necrosis factor-like weak inducer of apoptosis (TWEAK) in the serum and the rectus abdominis muscle in patients with gastric cancer and its relationship with the nutritional status. Method Clinical data of 102 patients with gastric cancer (gastric cancer group) and 53 patients with benign abdominal disease (control group) who were admitted to Zhejiang Province People's Hospital from January 2008 to October 2013 were analyzed retrospectively. Enzyme-linked immunosorbent assay(ELISA) was used to detect the serum expression of TWEAK. Reverse transcription polymerase chain reaction (RT-PCR) and Western blot were used to detect the mRNA and protein expression of TWEAK in the rectus abdominis muscle. Relationship between TWEAK expression and nutritional status of gastric cancer patients was examined. The relative expression level of TWEAK protein in serum of gastric cancer group and control group was 0.403±0.065 and 0.148±0.036 respectively. The relative expression of TWEAK mRNA in the rectus abdominis muscle tissue was 0.313±0.089 (gastric cancer group) and 0.118±0.005 (control group). The relative expression of TWEAK protein in the rectus abdominis muscle tissue was 0.197±0.064 (gastric cancer group) and 0.066±0.014 (control group), and the differences were statistically significant (both P=0.000). The high expression of TWEAK (high than median) in rectus abdominis muscle of gastric cancer patients was related to the percentage of more than 10% decline in body weight (P=0.000), the small percentage of ideal body weight at the time of admission (P=0.000), BMI<20 kg/m 2 (P=0.023), higher NRS2002 nutritional risk screening score (P=0.000), lower prognostic nutrition index (P=0.000) and serum albumin <35 g/L (P=0.000). The expression of TWEAK in serum and rectus abdominis muscle of gastric cancer patients up-regulates compared to non-tumor patients. The expression level of TWEAK in the rectus abdominis muscle of gastric cancer patients is closely related to poor nutritional status, suggesting that TWEAK may play a key role in the process of cachexia of gastric cancer patients.

Fifteen healthy old people mean age 84 years (range 80-91 years), were examined to assess the effect of advanced age on the microecology of the upper gastrointestinal tract. Twelve of 15 (80%) were hypochlorhydric with pH 6.6 (0.3) (mean (SEM) and a mean bacterial count of 10(8) colony forming units (CFU) per ml (range 10(5)-10(10)) in fasting gastric aspirate. Normochlorhydric subjects had low counts (< or = 10(1) CFU/ml). The microbial flora was dominated by viridans streptococci, coagulase negative staphylococci, and Haemophilus sp. Only one subject harboured significant concentrations of Gram negative bacilli with Escherichia coli (10(4-5) CFU/ml) and Klebsiella (10(4-5)). Strict anaerobes were not found. The total concentration of short chain fatty acids in gastric aspirate was 10.6 (2.9) mmol/l (mean (SEM). Absence of significant, intraluminal fermentation of xylose to CO2 was shown by the 14C-d Xylose breath test, and ambulatory manometry showed preserved fasting motility pattern of the small intestine. Serum immunoglobulins were normal. Advanced age is accompanied by fasting hypochlorhydria and colonisation with mainly Gram positive flora in the upper gut. Other factors than old age and fasting hypochlorhydria are required for colonisation with Gram negative bacilli. PMID:1446855

The aim of this study was to demonstrate epidemiological, clinical and endoscopic characteristics of acute upper gastrointestinal bleeding (UGIB) with special reference to peptic ulcer bleeding (PUB). The study included 2198 consecutive patients referred to our emergency department due to acute UGIB from January 2008 to December 2012. All patients underwent urgent upper GI endoscopy within 24 hours of admission, and 842 patients diagnosed with PUB were enrolled and prospectively followed-up. The cumulative incidence of UGIB was 126/100,000 in the 5-year period. Two out of five patients had a bleeding peptic ulcer; in total, 440 (52.3%) had bleeding gastric ulcer, 356 (42.3%) had bleeding duodenal ulcer, 17 (2%) had both bleeding gastric and duodenal ulcers, and 29 (3.5%) patients had bleeding ulcers on gastroenteric anastomoses. PUB was more common in men. The mean patient age was 65.9 years. The majority of patients (57%) with PUB were taking agents that attenuate the cytoprotective function of gastric and duodenal mucosa. Rebleeding occurred in 77 (9.7%) patients and 47 (5.9%) patients required surgical intervention. The 30-day morality was 5.2% and 10% of patients died from uncontrolled bleeding and concomitant diseases. In conclusion, PUB is the main cause of UGIB, characterized by a significant rebleeding rate and mortality.

Management of a postbulbar duodenal ulcer and stricture causing gastric outlet obstruction: A case report.

Peptic ulcer disease has significantly decreased over the past several decades making the need for definitive surgical intervention an infrequent occurrence. A 44-year-old Caucasian female was sent to the emergency department by her primary care physician for right upper quadrant abdominal pain which had been intermittent for the past two months but acutely worsened over the last five days. During this time, she was unable to tolerate oral intake with intractable nausea and vomiting. Upper GI endoscopy revealed a tight stricture in the second part of the duodenum and antral biopsy was Helicobacter pylori negative. Patient underwent two rounds of balloon dilation with short lived symptomatic relief. An open pylorus-preserving duodenal stricturoplasty using a Heineke-Mikulicz technique was then performed. The operation was successful and the patient has had no reoccurrence of her symptoms. Gastric outlet obstruction is an uncommon complication of peptic ulcer disease in respect to chronic nonsteroidal anti-inflammatory drug use. The unique location of the patient's stricture and her desire to minimize post-operative GI alterations demanded a review of surgical options and identified the benefits of maintaining the patient's original anatomy versus choosing an extra-anatomic approach. This case presented a unique challenge and demonstrated the need for definitive surgical interventions in the treatment of peptic ulcer induced gastric outlet obstruction. This case adds support for the direct anatomic treatment of duodenal strictures when conservative measures fail and perhaps promotes further development of laparoscopic management of gastric outlet obstruction in the future.

Amplification of proto-oncogenes associated with their over-expression is one of the critical carcinogenic events identified in human cancer cells. In many cases of human gastric cancer, a proto-oncogene ERBB-2 is co-amplified with CAB1 genes physically linked to ERBB-2, and both genes are over-expressed. The amplified region containing ERBB-2 and CAB1 was named 17q12 amplicon from its chromosomal location. The syntenic region corresponding to the 17q12 amplicon is well conserved in mouse. In this study we isolated and characterized a novel mouse gene that locates telomeric to the mouse syntenic region. Northern blot analysis using the mouse cDNA and a cloned partial cDNA of human homolog disclosed a unique expression pattern of the genes. They are expressed predominantly in the gastrointestinal (GI) tract and in the skin at a lower level. Moreover, in the GI tract, the expression is highly restricted to the esophagus and stomach. Thus, we named the mouse gene Gasdermin (Gsdm). This is the first report of a mammalian gene whose expression is restricted to both upper GI tract and skin. Interestingly, in spite of its expression in normal stomach, no transcript was detected by Northern blot analysis in human gastric cancer cells. These data suggest that the loss of the expression of the human homolog is required for the carcinogenesis of gastric tissue and that the gene has an activity adverse to malignant transformation of cells.

To evaluate the impact of dosage form relevant levels of a polymeric precipitation inhibitor and of lipid excipients on supersaturation of upper gastrointestinal contents with albendazole, a lipophilic weak base. Albendazole concentrations in stomach and in duodenum were evaluated after administration of 1) a suspension in water (Susp-Control), 2) a suspension in water in which hydroxyprolylmethylcellulose E5 (HPMC E5) had been pre-dissolved (Susp-HPMC), and 3) and 4) two contrasting designs of lipid based suspensions dispersed in water (Susp-IIIA and Susp-IV), on a cross-over basis to fasted healthy adults. Limited, but statistically significant supersaturation of duodenal contents was observed after Susp-HPMC, Susp-IIIA, and Susp-IV; supersaturation was more consistent after Susp-HPMC administration. Based on total albendazole amount per volume, gastric secretions did not significantly alter volumes of bulk gastric contents during the first 40min post administration of a glass of non-caloric water-based fluid. Αlbendazole gastric concentrations were higher than in the administered suspensions, but similar for all four formulations. Gastric emptying of albendazole after administration of Susp-Control or Susp-HPMC was slower than after administration of Susp-IIIA or Susp-IV. Small amounts of HPMC E5 were as effective as lipid excipients in achieving supersaturation of duodenal contents with albendazole, a fast precipitating weak base, in fasted adults. However, compared with the effect of HPMC E5 the effect of lipid excipients was delayed and variable. Copyright © 2016 Elsevier B.V. All rights reserved.

Gastric juice plays a crucial role in the physiology of the stomach. The aim of this study is to evaluate associations among the pH of gastric juice, atrophic gastritis (AG), intestinal metaplasia (IM), pepsinogen, and Helicobacter pylori infection. Gastric biopsies and juice were collected from 46 subjects who underwent endoscopies at Seoul National University Bundang Hospital between November 2011 and March 2013. H. pylori , AG and IM were evaluated, and pepsinogen I or II, I/II ratio, and interleukin (IL)-1β levels were measured. The mean pH of gastric juice was higher in the H. pylori -positive group (n=17) than that in the H. pylori -negative group (n=29) (4.54 vs 2.46, p=0.002). When patients were divided into pH ＜3 (n=28) and pH ≥3 (n=18) groups, H. pylori was lower in the pH ＜3 group (21.4%) than in the pH ≥3 group (61.1%) (p=0.007). The pH ≥3 group demonstrated AG and IM more frequently than the pH ＜3 group in the body (p=0.047 and p=0.051, respectively) but not in the antrum. There were no differences in pepsinogen I or II, I/II ratio, and IL-1β levels between the two groups. There is a relationship between chronic H. pylori infection and gastric juice pH ≥3, which may originate from AG and IM in the body.

Here we report an autopsy case of asphyxia due to aspiration of a salmon egg (ikura) into the airway. The patient was a 19-month-old girl. During breakfast, she put salmon eggs into her mouth, and began to walk. She slipped, fell down, and collapsed. She was pronounced dead following 2 h of resuscitation. The body was autopsied 28 h after death. The gastric contents consisted of rice, orange sections, and white salmon eggs. The lungs were deeply congested and over-inflated. In the right lung, areas of atelectasis in the upper and middle lobes were seen. A yellow salmon egg (8 mm in diameter) was found in the trachea. Although fish eggs are consumed throughout the world, reports of this sort are limited. The aspiration of fish eggs is under-acknowledged and underreported. The importance of preventive measures needs to be emphasized to parents and caregivers. © 2016 Japan Pediatric Society.

A 40-year-old previously healthy white man presented to the emergency department at American University of Beirut Medical Center, Beirut, Lebanon, with severe upper abdominal pain of 36-hour duration. The pain started a few hours after the intake of a single tablet of tiaprofenic acid and became more intense after the intake of another tablet 24 hours later. He had no other symptoms. He had no prior upper gastrointestinal (GI) symptoms, ulcer disease, steroidal or nonsteroidal anti-inflammatory drug use, or ethanol intake. Physical examination revealed mild upper abdominal tenderness. Complete blood count, amylase, lipase, and liver function tests were unremarkable. Computed tomography of the abdomen showed marked thickening of the duodenal wall with surrounding mesenteric streaking. Upper GI endoscopy revealed extensive ulceration involving the duodenal bulb, apex, and proximal D2, as well as a few gastric erosions. Histopathologic examination of duodenal biopsy samples showed extensive epithelial cell necrosis and infiltration of the lamina propria with neutrophils and eosinophils. The patient responded well to rabeprazole 20 mg BID and remains well 5 months later. We performed a literature search of PubMed for all English-language articles published between January 1970 and present (June 2007) using the key words tiaprofenic acid, nonsteroidal anti-inflammatory drugs, NSAID, duodenitis, duodenal erosion, duodenal ulcer, gastritis, gastric erosion, gastric ulcer, or peptic ulcer. We reviewed all randomized controlled trials involving NSAIDs found using PubMed, with a focus on their GI adverse effects. Based on the PubMed search, there were no published reports of acute transmural duodenitis and complicated duodenal ulcers associated with short-term exposure to tiaprofenic acid or other NSAIDs. The Naranjo adverse drug reaction (ADR) probability scale was used and a score of 6 was obtained, indicating a probable ADR from tiaprofenic acid use. We report a patient who developed symptomatic severe transmural duodenitis and periduodenal mesenteric streaking, consistent with a complicated ulcer, probably associated with very short-term exposure to tiaprofenic acid.

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.

To determine gastric emptying, blood pressure, mesenteric artery blood flow, and blood glucose responses to oral glucose in Parkinson's disease. Twenty-one subjects (13 M, 8 F; age 64.2 ± 1.6 years) with mild to moderate Parkinson's disease (Hoehn and Yahr score 1.4 ± 0.1, duration of known disease 6.3 ± 0.9 years) consumed a 75 g glucose drink, labelled with 20 MBq (99m)Tc-calcium phytate. Gastric emptying was quantified with scintigraphy, blood pressure and heart rate with an automated device, superior mesenteric artery blood flow by Doppler ultrasonography and blood glucose by glucometer for 180 min. Autonomic nerve function was evaluated with cardiovascular reflex tests and upper gastrointestinal symptoms by questionnaire. The mean gastric half-emptying time was 106 ± 9.1 min, gastric emptying was abnormally delayed in 3 subjects (14%). Systolic and diastolic blood pressure fell (P < 0.001) and mesenteric blood flow and blood glucose (P < 0.001 for both) increased, following the drink. Three subjects (14%) had definite autonomic neuropathy and 8 (38%) had postprandial hypotension. There were no significant relationships between changes in blood pressure, heart rate or mesenteric artery blood flow with gastric emptying. Gastric emptying was related to the score for autonomic nerve function (R = 0.55, P < 0.01). There was an inverse relationship between the blood glucose at t = 30 min (R = -0.52, P < 0.05), while the blood glucose at t = 180 min was related directly (R = 0.49, P < 0.05), with gastric emptying. In mild to moderate Parkinson's disease, gastric emptying is related to autonomic dysfunction and a determinant of the glycaemic response to oral glucose.

Improving early detection of gastric cancer: a novel systematic alphanumeric-coded endoscopic approach.

Despite extensive worldwide use of standard esophagogastroduodenoscopy (EGD) examinations, gastric cancer (GC) is one of the most common forms of cancer and ranks as the most common malignant tumor in East Asia, Eastern Europe and parts of Latin America. Current limitations of using non systematic examination during standard EGD could be at least partially responsible for the low incidence of early GC diagnosis in countries with a high prevalence of the disease. Originally proposed by Emura et al., systematic alphanumeric-coded endoscopy (SACE) is a novel method that facilitates complete examination of the upper GI tract based on sequential systematic overlapping photo-documentation using an endoluminal alphanumeric-coded nomenclature comprised of eight regions and 28 areas covering the entire surface upper GI surface. For precise localization or normal or abnormal areas, SACE incorporates a simple coordinate system based on the identification of certain natural axes, walls, curvatures and anatomical endoluminal landmarks. Efectiveness of SACE was recently demonstrated in a screening study that diagnosed early GC at a frequency of 0.30% (2/650) in healthy, average-risk volunteer subjects. Such a novel approach, if uniformly implemented worldwide, could significantly change the way we practice upper endoscopy in our lifetimes.

Mucormycosis is a rare fungal infection of the mucorales order, which affects mostly immunocompromised patients. The association with emphysematous gastritis is rare and often fatal produced by gas -forming bacteria. We report the case of a trauma patient with type 1 diabetes mellitus, and diabetic ketoacidosis complicated with gastric mucormycosis associated with emphysematous gastritis. A male aged 32 who is involved in a car accident, who suffered head trauma, is admitted to the Intensive Care Unit, presenting diabetic ketoacidosis and upper gastrointestinal bleeding. An endoscopy was performed and an erosive esophagitis Class C, ischemia and gastric necrosis was found. A computed tomography scan showed emphysematous gastritis and gastric necrosis. He underwent total gastrectomy with a histopathology report of gastric mucormycosis. After the surgical procedure the patient died because of sepsis secondary to pulmonary mucormycosis Mucormycosis is a rare fungical disease which infrequently affects the gastrointestinal tract, being the stomach the most affected site. The mortality is high if the diagnosis is not done promptly and appropriate treatment is given. Suspecting its existence is necessary in patients with immunocompromised status to diagnose and provide timely treatment to increase survival, because of its high mortality. Copyright © 2015.

A case-control study of dietary factors and gastric cancer was conducted between September 1986 and March 1989 in the Barcelona metropolitan area, Spain. In all 117 cases with histologically confirmed diagnosis of gastric adenocarcinoma were matched on sex, age and possession of a telephone to 234 population controls. Of the controls 188 (80.3%) were selected by random digit telephone dialing and 46 (19.7%) by neighbourhood of residence. Information about frequency and amount of consumption of 89 alimentary items was gathered by questionnaire, and cases and controls were interviewed in their homes by trained interviewers. The gastric cancer risk decreased in proportion to vitamin C intake. In multivariate analysis adjusting for major covariables, energy and vitamin A intake, the estimated odds ratio (OR) for the upper quartile of vitamin C intake was 0.3 (95% confidence interval [CI]: 0.1-0.8). After adjustment for major covariables, calories and vitamin C intake, vitamin A did not show significant association with the gastric cancer risk. Our findings are consistent with previous case-control studies and with the hypothesis that vitamin C may inhibit the intragastric nitrosation process.

Lubiprostone is effective for patients with chronic constipation. This agent sometimes causes upper gastrointestinal symptoms, such as nausea, which is one of the chief reasons for discontinuation. However, the etiology of and strategy against bothersome gastrointestinal symptoms of lubiprostone remain unclear. The goal of this study was to investigate the influence of lubiprostone on the gastric-emptying profile of healthy adults. The effect of domperidone on gastric emptying and gastrointestinal symptoms after lubiprostone administration were also assessed. 80 healthy male participants underwent ¹³C acetate breath testing to evaluate gastric emptying. The test meal comprised 200 kcal of a standard liquid nutrient. Each participant underwent 3 random breath tests with: 1) no premedication; 2) 24 µg of lubiprostone 30 minutes prior to the study; and 3) 24 µg of lubiprostone plus 10 mg of domperidone 30 minutes prior to the study. Gastrointestinal symptoms (heartburn, regurgitation, epigastric pain, fullness, distress feeling) during testing were evaluated using a 7-point scoring system. Gastric emptying was significantly delayed by the administration of lubiprostone. Among all 8 subjects, 4 reported heartburn after taking lubiprostone, whereas this symptom was not found when subjects received concomitant domperidone. However, gastric emptying showed little change between lubiprostone alone and lubiprostone plus domperidone. Lubiprostone delayed gastric emptying of liquid in healthy adults, which could be associated with the gastrointestinal symptoms caused by the agent. Domperidone seemed effective against such gastrointestinal symptoms after administration of lubiprostone. This effect seemed unrelated to gastric motility.

the paper presents a rare case of metachronous gastric metastasis of uterine cervix cancer, clinically manifested through severe pyloric stenosis. 49-year-old patient, operated on in January 2009, with uterine cervix cancer (Squamous cell carcinoma T2bN1M0), is hospitalized in August 2011 with pyloric stenosis: epigastric pains, abundant, stasis, late postprandial emesis, significant weight loss, stomach form visible upon abdomen inspection. Endoscopy: antral stenosis with intact gastric mucosa, and CT-scan: circumferential intramural gastric tumor, stomach dilated in the upper part, lack of cleavage between the tumor and the liver bed of the gall bladder. CEA increased to 13,78 (below 5), CA 19-9 slightly increased 29.9 (below 27). The case is considered as a second neoplasia and a D2 subtotal gastrectomy was performed, with 1 positive ganglion out of 27 on block with atypical hepatectomy of segments 4-5 for liver invasion, the final mounting being Y Roux. The histopathological examination shows a gastric metastasis of squamous carcinoma, of uterine cervix origin, the invaded perigastric ganglion having the same aspect of uterine cervix carcinoma. The post-surgery evolution was favorable, under chemo radiotherapy the patient being alive without relapse at 9 months post-surgery. In the literature there are 2 more cases of gastric metastasis of uterine cervix carcinoma, and 4 of uterine carcinoma without topographic indication, but without the histological documentation of the tumor filiation, without data related to resecability or follow-up, the case at hand being, from this perspective, the first documented resectable metachronous gastric metastasis from a cervix uteri carcinoma.

Autoimmune gastritis (AIG) is a gastric pathologic condition affecting the mucosa of the fundus and the body and eventually leading to hypo-achlorhydria. We report our clinical and pathological experience with AIG. Data from patients with a diagnosis of AIG seen in the period January 2002-December 2012 were retrieved. Only patients with complete sets of biopsies were analyzed. Data from 138 patients were available for analysis. Pernicious anemia was present in 25% of patients, iron deficiency anemia was found in 29.7% of patients, hypothyroidism in 23% of patients, type 1 diabetes in 7.9% of patients, and vitiligo in 2.8% of patients. Parietal cell antibodies were positive in 65% of patients, and no patient had serology positive for celiac disease. All gastric biopsies showed glandular atrophy associated with enterochromaffin-like (ECL)-cells hyperplasia, features limited to the mucosa of the fundus and body, and focal glandular intestinal metaplasia. Helicobacter pylori was negative in all cases. AIG was strongly associated with anemia; atrophy, intestinal metaplasia and ECL hyperplasia in the gastric fundus and body are hallmarks of this condition.

The following is a case report of moderately differentiated tubular adenocarcinoma of the stomach with widespread thrombosis of the portal vein, for which chemotherapy proved effective. A 75-year-old man presented to the clinic with a new onset ofmalaise. The patient had anemia, elevation ofliver and biliary enzymes, and significantly elevated CA19-9 levels at 43,581 U/mL and CEA levels at 2,560 ng/mL. An upper endoscopy revealed a mass lesion extending from the fundus to the pylorus as well as to the duodenum along the smaller curvature of the stomach. A biopsy revealed moderately differentiated tubular adenocarcinoma. Abdominal CT showed a mass lesion extending from the body of the stomach and penetrating through the gastric wall, and extensive lymphadenopathy in the surrounding areas. In addition, multiple thromboses were identified in the portal vein and its tributaries, including the inferior mesenteric vein, splenic vein, and intrahepatic capillaries. The patient subsequently received a single round ofS -1 and CDDP. The tumor demonstrated a marked response; the tumor size and lymphadenopathy showed a significant improvement and the CA19-9 level decreased. Because the patient's condition deteriorated, this chemotherapy regimen was discontinued. The patient was switched to S-1 monotherapy and is still alive today, 2 years 10 months after the initial diagnosis.

Long-term follow-up was performed 16 to 26 years after conservative (group I, n = 18) and operative (group II, n = 38) treatment of 56 patients who had infantile hypertrophic pyloric stenosis (IHPS). The study encompassed the scintigraphic determination of gastric emptying rates for solids and liquids, an interview to obtain medical history and ascertain whether a current disorder of the upper gastrointestinal tract was present, and a clinical examination. Gastric emptying rates were measured on two different days for solids and liquids. The standard solid meal consisted of two scrambled eggs, two slices of toast, and 20 g of margarine. The gastric emptying rate for liquids was measured using 300 mL of apple juice. The scrambled eggs and apple juice were each marked with 2.2 MBq technetium 99m-sulphur-colloid. Two control collectives were used in this study; one group (physicians) served to create a reference curve for gastric emptying, and the other group, with the same age and gender distributions as those of the patients, served to evaluate the frequency of gastrointestinal complaints, by means of a questionnaire. There was no significant rate difference for gastric emptying between the patients treated conservatively or surgically and the controls. No association could be construed between the frequency of gastrointestinal symptoms or disorders and the gastric emptying rates for solids and liquids. The results presented here substantiate that clinically relevant disturbances of stomach motility after IHPS appear to be rare.

Gastric bezoars are a rare condition associated with situations of gastric dysmotility and prior gastric surgery, though sometimes they can present without any risk factor. We describe the first successful treatment in medical literature of a large gastric bezoar in the outpatient setting through endoscopic fragmentation. A 76-year-old man was referred to our outpatient endoscopy clinic because of dyspepsia and epigastric pain. Upper GI endoscopy with a standard endoscope revealed a 10-cm-diameter gastric phytobezoar with necrotic pressure ulcer of the angulus. We fragmentized the bezoar into smaller pieces, with complete dissolution and without any complication. The patient was then promptly discharged home with a medical therapy. Follow-up endoscopy at 6 months showed the total disappearance of any residual fibers. Different types of bezoars are described in literature, of which phyto- and trychobezoars are the most frequent. They can be absolutely asymptomatic or can arise with epigastric pain, pressure ulcer bleeding, gastrointestinal perforation or small bowel obstruction. The treatment is debated though endoscopic removal or fragmentation with the help of Coca-Cola lavages has showed the best success rate. The main experiences in literature concern hospitalized patients or describe treatment techniques which require overnight stays. An effective and rapid treatment in the outpatient setting is described in our experience, without short- or long-term complications. The endoscopic fragmentation of large gastric bezoars in the outpatient setting is safe with a good clinical course. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

The metabolic syndrome (MS) is a complex disorder characterized by a number of cardiovascular risk factors usually associated with central fat deposition and insulin resistance. Many different medical treatments are available for MS, including bariatric surgery, which improves all risk factors. The present study aimed to evaluate, at the Clinic of Gastroenterology and Obesity Surgery (Brazil), the accuracy of different anthropometric indexes and their correlation with improvement of the MS factors in the postoperative (6-month) period. This was a retrospective study of 140 patients who had undergone gastric bypass. Most of the patients were women (79.3%). The mean body mass index was 44.17 kg/m(2). We evaluated the weight of the subjects, the presence of diabetes mellitus and hypertension as co-morbidities, and the biochemical parameters. The anthropometric indexes tested included the percentage of excess weight loss, amount lost in kilograms, difference in the body mass index, percentage of initial weight lost, percentage of excess body mass index lost (%EBL), and percentage of initial fat mass lost. The %EBL had a Spearman's correlation coefficient of 0.55 (P <.0001) for the difference between the MS factors before and after Roux-en-Y gastric bypass. The receiver operating characteristic curve for the %EBL resulted in an area under the curve of 0.846 (P = 0.0001) and a sensitivity and specificity of 100% and 61.29%, respectively, for a cutoff value of 64.55%. The %EBL was the best method to report weight loss and the improvement in MS in morbidly obese subjects after Roux-en-Y gastric bypass.

Enzymatically synthesized glycogen (ESG) has high solubility and its solution has low osmotic pressure. Therefore ESG solution could be rapidly absorbed and could be adequate for water rehydration and carbohydrate supplementation during exercise. The object of this study was to evaluate the gastric emptying time and plasma glucose elevation after an administration of ESG solution in comparison with another carbohydrate solution by using a laboratory animal. Male BALB/c mice were administered 10% w/v solution of glucose, maltodextrin, starch, naturally synthesized glycogen (NSG) and ESG at a dose of 20 µL/g body weight for the measurement of gastric emptying rate (Experiment 1) and 10 µL/g body weight for the measurement of plasma glucose elevation (Experiment 2). The osmolarity of gastric content was lower in the ESG and maltodextrin group than the other carbohydrate group. Weight of gastric fluid was significantly lower in the ESG and water group than the glucose group (p<0.01). Plasma glucose level was significantly lower in the ESG group than the glucose group from 0 to 60 min after administration (p<0.01), whereas plasma glucose level was same from 60 to 120 min for the ESG and glucose group (p=0.948). In Experiment 3, BALB/c mice ran on a treadmill for 2 h and were administered 8% of ESG or glucose solution (1.75, 3.5 or 7.0 µL/g body weight) every 20 min during running. There was no difference in post-exercise muscle glycogen level. These data suggest that 1) ESG beverage does not disturb water absorption because of its short gastric emptying time and 2) ESG slowly elevates plasma glucose level and maintains it for a prolonged time compared to the glucose solution.

Morgagni hernia is considered to be the rarest form of all diaphragmatic hernias. It develops through a congenital defect in the retrosternal area. Usually asymptomatic, this entity can lead to life-threatening complications such as incarceration, strangulation or volvulus of the herniated viscus. We hereby report a rare case of organoaxial gastric volvulus producing through the foramen of Morgagni in a 78-year-old woman. The full diagnosis was made by upper gastro-intestinal series and multidetector computed tomography (MDCT). The basic anatomy, physiopathology, diagnostic methods, complications and surgical treatment of Morgagni hernia are briefly reviewed.

Gastric bypass is increasingly used in morbidly obese patients to achieve significant reduction of body weight and fat mass and concurrent improvement in co-morbidities. We report the case of a 53-year-old male patient (141 kg, BMI 50 kg/m2), successfully treated by amiodarone for supraventricular arrythmia, who underwent Roux-en-Y gastric bypass (RYGBP). 6 months after surgery, he had lost 45% of his preoperative weight (44.8% of weight loss was lean mass) and developed amiodarone-induced subclinical hyperthyroidism. We hypothesize the following sequence of events: weight loss after RYGBP, therefore fat loss, decrease in distribution volume of amiodarone inducing iodine overload and hyperthyroidism, reinforcing weight loss and particularly loss of lean mass. This report emphasizes the importance of careful monitoring of weight and body composition changes after RYGBP. In this situation, checking thyroid status is recommended, especially when there is a history of thyroid disease or potentially toxic thyroid medication.

Metastatic disease to the stomach or duodenum is an infrequent diagnosis, and head and neck squamous cell carcinoma (HNSCC) is one of the least common primary malignancies that lead to gastric or duodenal metastases. We report the case of a 65-year-old man with human immunodeficiency virus infection and previously diagnosed HNSCC who presented with melena. The patient had a percutaneous endoscopic gastrostomy tube placed 3 months prior to his presentation. Laboratory testing was significant for normocytic anemia and a digital rectal examination was positive for melena. Esophagogastroduodenoscopy revealed numerous cratered nodules with contact bleeding in the stomach as well as the duodenum that appeared malignant. Biopsies of the gastric and duodenal nodules were positive for p40 and CK 5/6, consistent with metastatic squamous cell carcinoma.

A 60-year-old woman underwent upper gastrointestinal endoscopy for an abnormality identified during routine examination. The lower gastric corpus showed a type 0-I elevated lesion with a faded mucosa and an area of converging mucosal folds in contact with the lesion. Biopsy indicated the former to be a high-grade adenoma and the latter to be a mucosa-associated lymphoid tissue (MALT) lymphoma. At the same time, Helicobacter pylori infection was diagnosed. Eradication therapy was administered to manage the MALT lymphoma; this resulted in improvement after 3 months. Endoscopic submucosal dissection was performed for the elevated lesion, and subsequent histopathology showed contact between the MALT lymphoma and gastric cancer. Therefore, the patient was diagnosed with a collision tumor. Concurrent cancers are increasingly reported and should be considered during examination.

The purpose of this study was to investigate the gastroprotective effects of bovine milk on an acidified ethanol (HCl-ethanol) mixture that induced gastric ulcers in a mouse model. Mice received different doses of commercial fresh bovine milk (5, 10, and 20 mL/kg of body weight) by oral gavage once a day for 14 d. One hour after the last oral administration of bovine milk, the HCl-ethanol mixture was orally intubated to provoke severe gastric damage. Our results showed that pretreatment with bovine milk significantly suppressed the formation of gastric mucosa lesions. Pretreatment lowered gastric myeloperoxidase and increased gastric mucus contents and antioxidant enzymes catalase and superoxide dismutase. Administration of bovine milk increased nitrate/nitrite levels and decreased the malondialdehyde levels and the expression of proinflammatory genes, including transcription factor nuclear factor-κB, cyclooxygenase-2, and inducible nitric oxide synthase in the stomach of mice. These results suggest that bovine milk can prevent the development of gastric ulcer caused by acid and alcohol in mice. Copyright © 2018 American Dairy Science Association. Published by Elsevier Inc.

2004-07-01

Gynostemma pentaphyllum is an oriental medicinal herb reputed to have broad-spectrum activities. The plant's principal saponin components are structurally similar to those found in ginseng plants and this similarity is assumed to be responsible for the claimed activities. The present study was undertaken to evaluate a G. pentaphyllum butanol fraction (GPB) for its anti-gastric ulcer activity using experimental models. Oral administration of the GPB at 200 and 400 mg/kg body wt. significantly inhibited gastric ulcer formation induced by indomethacin, HCl/EtOH and water-immersion restraint stress in rats. In pylorus-ligated rats, pretreatment with the GPB had no effect on gastric volume, pH or acidity output, thus indicating a lack of anti-secretory effect. In ethanol-induced ulcerated rats, gastric wall mucus and hexosamine content were markedly preserved by GPB pretreatment. The findings indicate that the butanol fraction of G. pentaphyllum possesses gastroprotective potential related to the preservation of gastric mucus synthesis and secretion.

To investigate whether omeprazole has improved morbidity-mortality among patients with upper gastrointestinal bleeding of non-variceal origin in comparison with ranitidine. Prospective, randomized and open study. We study 519 consecutive patients admitted to our Service between June 1991 and January 1993 for upper gastrointestinal bleeding of peptic origin, dividing the patients into two randomized groups that were homogeneous in terms of age, sex, previous history of gastric disease and upper gastrointestinal bleeding, intake of non-steroidal antiinflammatory drugs, and the severity of bleeding on admittance. Thus, Group A consisted of 252 patients treated immediately upon arrival at the emergency ward with 50 mg intravenous ranitidine, followed by a further 50 mg every 6 hours. Group B in turn consisted of 267 patients initially given a bolus dose of 80 mg omeprazole intravenously, followed by an additional 40 mg every 8 hours for 48 hours. Forty mg were subsequently administered every 12 hours until hospital discharge. Endoscopy was performed in all cases within the first 24 hours following admittance, those patients with active upper gastrointestinal bleeding resulted from Forrest-type ulcer of subjected to endoscopic sclerotherapy were excluded. Duodenal ulcer was the most common cause of bleeding, followed by gastric ulcer and acute lesions of the mucosa. Emphasis should be placed on the high incidence of previous non-steroidal antiinflammatory drug intake in our series (54.5%). We encountered no statistically significant differences between the two groups on comparing bleeding stigmata, transfusion requirements, recurrences, emergency surgery, the duration of hospital stay, and mortality. Both drugs were found to possess a similar efficacy in treating upper gastrointestinal bleeding of peptic origin.

Fat digestion by lingual lipase: mechanism of lipolysis in the stomach and upper small intestine.

Liao, T H; Hamosh, P; Hamosh, M

Ten to 30% of dietary fat is hydrolyzed in the stomach by lingual lipase, an enzyme secreted from lingual serous glands. We investigated the substrate specificity of this enzyme as well as the potential of lingual lipase to act in the upper small intestine i.e., in the presence of bile salts and lecithin. The data presented show that partially purified preparations of rat lingual lipase and the lipase in gastric aspirates of newborn infants have identical substrate specificity: medium-chain triglycerides were hydrolyzed at rates 5-8-fold higher than long-chain triglycerides; the rat and human enzymes do not hydrolyze the ester bond of lecithin or cholesteryl-ester. In contrast to pancreatic lipase, the hydrolysis of triglycerides by lingual lipase is not inhibited by lecithin. But, similar to pancreatic lipase the activity of lingual lipase is inhibited by bile salts, the extent of inhibition varying with its nature and concentration. This inactivation is not prevented by colipase but is partially averted by lipids and protein, suggesting that lingual lipase can remain active in the duodenum. The pH optimum of the enzyme (2.2-6.5 in the rat and 3.5-6.0 in human gastric aspirates) is compatible with continued activity in the upper small intestine, especially during the neonatal period, when the luminal pH is under 6.5. The marked variation in lipase activity levels in gastric aspirates of newborn infants is probably due to individual variations in enzyme amounts. The characteristics of the lipase are however identical in infants with low, intermediate or high activity levels.(ABSTRACT TRUNCATED AT 250 WORDS)

To determine the long-term effect of argon plasma coagulation (APC) of gastric inlet patches in the cervical esophagus for patients suffering from globus sensation. We intended to follow up all patients between 2004 and 2011 (n = 49) who received argon plasma ablation of gastric inlet patches for globus sensation at our clinic. Symptoms were assessed by a visual analogue scale (VAS) in 31 of 49 patients. Follow-up endoscopy of the upper gastrointestinal tract was performed to confirm residual or relapsed cervical inlet patches. After a median period of 27 months, APC was assessed as a successful therapy in 23 of 31 patients (74%). VAS scores decreased significantly from 7.6 to 4.0 in the long term. Twenty-two of 31 patients were willing to undergo follow-up endoscopy. Endoscopy revealed recurrent/residual gastric inlet patches after APC in 11 of 22 cases. These patients suffered from a significant relapse of symptoms in the postinterventional period (p < 0.001). This retrospective study indicates that APC of gastric inlet patches for the treatment of globus sensation might be a sufficient therapy option. Recurrences or residual heterotopic gastric mucosa are possible and seem to be associated with a relapse of symptoms. Therefore, endoscopic follow-up and retreatment might be necessary if globus sensation is not sufficiently eliminated. © 2013 S. Karger AG, Basel.

Pernicious anemia (also known as Biermer disease or anemia, Addison or Addisonian anemia, and Addison-Biermer anemia) is an autoimmune atrophic gastritis responsible for vitamin B12 malabsorption due to a deficiency of intrinsic factor. We report eight cases of pernicious anemia in Burkina Faso, collected over a 44-month period. The three criteria for diagnosis of pernicious anemia were: vitamin B12 deficiency, gastric disease (gastric histology) with presence of anti-intrinsic factor, and/or anti-gastric parietal cell antibodies in serum. All patients had anemia, with a mean hemoglobin level of 8.75 g/100 mL. The average mean corpuscular volume (MCV) was 122.1 fL the average mean corpuscular hemoglobin (MCH) 39.3 pg, the mean reticulocyte count 12.069 10(9)/L reticulocytes, and the mean rate of megaloblast marrow cells 17.2%. The serum vitamin B12 level ranged from 35 to 71 pmol/L. Antibodies against intrinsic factor were found in all eight patients. All ABO blood groups were present with a predominance (4 cases) of group O. Endoscopy found a normal fundic mucosa in three patients. Histology showed gastric atrophy and intestinal metaplasia for six patients (85.7%). Under B12 vitamin therapy, the course was favorable in all patients; seven patients also had 10 days of iron therapy. We recommend a gastric biopsy even in the absence of macroscopic gastric lesions on the upper gastrointestinal endoscopy.

Background/Aims Gastric juice plays a crucial role in the physiology of the stomach. The aim of this study is to evaluate associations among the pH of gastric juice, atrophic gastritis (AG), intestinal metaplasia (IM), pepsinogen, and Helicobacter pylori infection. Methods Gastric biopsies and juice were collected from 46 subjects who underwent endoscopies at Seoul National University Bundang Hospital between November 2011 and March 2013. H. pylori, AG and IM were evaluated, and pepsinogen I or II, I/II ratio, and interleukin (IL)-1β levels were measured. Results The mean pH of gastric juice was higher in the H. pylori-positive group (n=17) than that in the H. pylori-negative group (n=29) (4.54 vs 2.46, p=0.002). When patients were divided into pH <3 (n=28) and pH ≥3 (n=18) groups, H. pylori was lower in the pH <3 group (21.4%) than in the pH ≥3 group (61.1%) (p=0.007). The pH ≥3 group demonstrated AG and IM more frequently than the pH <3 group in the body (p=0.047 and p=0.051, respectively) but not in the antrum. There were no differences in pepsinogen I or II, I/II ratio, and IL-1β levels between the two groups. Conclusions There is a relationship between chronic H. pylori infection and gastric juice pH ≥3, which may originate from AG and IM in the body. PMID:28918609

The purpose of this study was to examine the gastric emptying and rehydration effects of hypotonic and hypertonic glucose-electrolyte drinks after exercise-induced dehydration. Eight healthy males lost ~1.8% body mass by intermittent cycling and rehydrated (150% of body mass loss) with a hypotonic 2% (2% trial) or a hypertonic 10% (10% trial) glucose-electrolyte drink over 60 min. Blood and urine samples were taken at preexercise, postexercise, and 60, 120, 180, and 240 min postexercise. Gastric and test drink volume were determined 15, 30, 45, 60, 90, and 120 min postexercise. At the end of the gastric sampling period 0.3% (2% trial) and 42.1% (10% trial; p < .001) of the drinks remained in the stomach. Plasma volume was lower (p < .01) and serum osmolality was greater (p < .001) at 60 and 120 min during the 10% trial. At 240 min, 52% (2% trial) and 64% (10% trial; p < .001) of the drinks were retained. Net fluid balance was greater from 120 min during the 10% trial (p < .001). When net fluid balance was corrected for the volume of fluid in the stomach, it was greater at 60 and 120 min during the 2% trial (p < .001). These results suggest that the reduced urine output following ingestion of a hypertonic rehydration drink might be mediated by a slower rate of gastric emptying, but the slow gastric emptying of such solutions makes rehydration efficiency difficult to determine in the hours immediately after drinking, compromising the calculation of net fluid balance.

As medidas da espessura da parede gástrica foram feitas no antro, corpo e corpo alto utilizando-se um ecoendoscópio radial com frequência de 12MHz e zoom máximo. a presença do BIG levou ao aumento da espessura da parede do corpo gástrico pelo aumento de espessura da sua camada muscular. Estas alterações são aparentemente transitórias já que após 30 dias da retirada do balão existiu uma tendência de retorno da espessura da parede aos valores observados antes do seu posicionamento. a utilização do balão intragástrico para tratamento da obesidade determina aumento transitório da espessura da parede do corpo gástrico causado pelo aumento da camada muscular.

Roux-en-Y Gastric Bypass Operation in Rats

Currently, the most effective therapy for the treatment of morbid obesity to induce significant and maintained body weight loss with a proven mortality benefit is bariatric surgery1,2. Consequently, there has been a steady rise in the number of bariatric operations done worldwide in recent years with the Roux-en-Y gastric bypass (gastric bypass) being the most commonly performed operation3. Against this background, it is important to understand the physiological mechanisms by which gastric bypass induces and maintains body weight loss. These mechanisms are yet not fully understood, but may include reduced hunger and increased satiation4,5, increased energy expenditure6,7, altered preference for food high in fat and sugar8,9, altered salt and water handling of the kidney10 as well as alterations in gut microbiota11. Such changes seen after gastric bypass may at least partly stem from how the surgery alters the hormonal milieu because gastric bypass increases the postprandial release of peptide-YY (PYY) and glucagon-like-peptide-1 (GLP-1), hormones that are released by the gut in the presence of nutrients and that reduce eating12. During the last two decades numerous studies using rats have been carried out to further investigate physiological changes after gastric bypass. The gastric bypass rat model has proven to be a valuable experimental tool not least as it closely mimics the time profile and magnitude of human weight loss, but also allows researchers to control and manipulate critical anatomic and physiologic factors including the use of appropriate controls. Consequently, there is a wide array of rat gastric bypass models available in the literature reviewed elsewhere in more detail 13-15. The description of the exact surgical technique of these models varies widely and differs e.g. in terms of pouch size, limb lengths, and the preservation of the vagal nerve. If reported, mortality rates seem to range from 0 to 35%15. Furthermore, surgery has been carried out almost exclusively in male rats of different strains and ages. Pre- and postoperative diets also varied significantly. Technical and experimental variations in published gastric bypass rat models complicate the comparison and identification of potential physiological mechanisms involved in gastric bypass. There is no clear evidence that any of these models is superior, but there is an emerging need for standardization of the procedure to achieve consistent and comparable data. This article therefore aims to summarize and discuss technical and experimental details of our previously validated and published gastric bypass rat model. PMID:22710348

A rhamnogalacturonan (RGal) isolated from Acmella oleracea (L.) R.K. Jansen administered by oral route showed gastroprotective activity against acute lesions induced by ethanol. In this study, we investigated the gastric ulcer healing effect of RGal and its mechanisms of action. Intraperitoneal treatment of animals with RGal protected the gastric mucosa against acute lesions induced by ethanol, with participation of gastric mucus. Furthermore, in the chronic ulcer model, oral administration of RGal accelerates the gastric ulcer healing, accompanied by increasing of cellular proliferation and gastric mucus content, reducing inflammatory parameters and oxidative stress. In addition, the repeated 7 days-treatment of animals with RGal did not show alterations of clinical and behavioral symptoms, body and organs weights or plasmatic biochemical parameters. Collectively, these results showed that RGal has an interesting antiulcerogenic activity and could constitute an attractive molecule of interest for the development of new antiulcer agents.

This study investigated the in vivo protective effect of cyanidin 3-glucoside (C3G) against ethanol-induced gastric lesions in rats. The experimental rats were treated with 80% ethanol after pretreatment with various doses of C3G (4 and 8 mg/kg of body weight), and the control rats received only 80% ethanol. Oral pretreatment with C3G significantly inhibited the formation of ethanol-induced gastric lesions and the elevation of the lipid peroxide level. In addition, pretreatment with C3G significantly increased the level of glutathione and the activities of radical scavenging enzymes, such as superoxide dismutase, catalase, and glutathione peroxidase, in gastric tissues. These results suggest that the gastroprotective effect of C3G removes the ethanol-induced lipid peroxides and free radicals and that it may offer a potential remedy for the treatment of gastric lesions.

The current study presents a rare case of cellular schwannoma originating from the gastric wall. Computed tomography revealed a 5.6×5.3×4.0-cm 3 solid mass located in the posterior wall of the stomach. Open laparotomy confirmed its mesenchymal origin. Microscopically, the tissue was composed of spindle-shaped and fascicularly-arranged cells, but mitotic figures were rare. Immunohistochemical staining showed that the tumor was negative for cluster of differentiation (CD)117, CD34, smooth muscle actin and desmin, but positive for S-100 and Ki67. The patient presented no evidence of recurrence and metastasis during follow-up. Gastric cellular schwannomas may be diagnosed by clinical characteristics, histological observations and immunohistochemical markers.

There is considerable information on the methylation of the promoter regions of different genes involved in gastric carcinogenesis. However, there is a lack of information on how this epigenetic process differs in tumors originating at different sites in the stomach. The aim of this study is to assess the methylation profiles of the MLH1, MGMT, and DAPK-1 genes in cancerous tissues from different stomach sites. Samples were acquired from 81 patients suffering stomach adenocarcinoma who underwent surgery for gastric cancer in the Lithuanian University of Health Sciences Hospital Kaunas Clinics in 2009-2012. Gene methylation was investigated with methylation-specific PCR. The study was approved by the Lithuanian Biomedical Research Ethics Committee. The frequencies of methylation in cancerous tissues from the upper, middle, and lower thirds of the stomach were 11.1, 23.1, and 45.4%, respectively, for MLH1; 22.2, 30.8, and 57.6%, respectively, for MGMT; and 44.4, 48.7, and 51.5%, respectively, for DAPK-1. MLH1 and MGMT methylation was observed more often in the lower third of the stomach than in the upper third (p < 0.05). In the middle third, DAPK-1 promoter methylation was related to more-advanced disease in the lymph nodes (N2-3 compared with N0-1 [p = 0.02]) and advanced tumor stage (stage III rather than stages I-II [p = 0.05]). MLH1 and MGMT methylation correlated inversely when the tumor was located in the lower third of the stomach (coefficient, -0.48; p = 0.01). DAPK-1 and MLH1 methylation correlated inversely in tumors in the middle-third of the stomach (coefficient, -0.41; p = 0.01). Gene promoter methylation depends on the gastric tumor location.

Development and analytical validation of an enzyme linked immunosorbent assay for the measurement of canine gastric lipase immunoreactivity in serum

PubMed Central

2004-01-01

Abstract The objective of this study was to develop and analytically validate an enzyme linked immunosorbent assay (ELISA) for measurement of canine gastric lipase immunoreactivity (cGLI). A sandwich ELISA was developed using canine gastric lipase (cGL) purified from canine stomachs and polyclonal antibodies directed against cGL, raised in rabbits and purified by affinity chromatography. The assay was validated by determination of sensitivity, working range, linearity, accuracy, precision, reproducibility, and the upper limit of the control range by determining the 97.5th percentile of serum cGLI concentration in 74 healthy canines. Sensitivity and working range in serum were 200 ng/L and 200 to 39 160 ng/L, respectively. Observed to expected ratios for dilutional parallelism for 3 serum samples and 3 dilutions ranged from 86.1% to 244.2% (mean ± standard deviation [s]; 125.4% ± 48.2%). Observed to expected ratios for spiking recoveries for 3 serum samples and 6 spiking concentrations ranged from 66.4% to 152.5% (mean ± s; 104.5% ± 22.9%). Intra-assay and interassay variabilities for 3 different serum samples were 25.5%, 9.4%, and 13.4% and 26.0%, 17.2%, and 14.4%, respectively. The upper limit of the control range for serum cGLI was 662 ng/L. We concluded that the ELISA for cGLI described here is highly sensitive and shows a wide working range. However, the validation characteristics for this assay are suboptimal and below values of approximately 2.000 ng/L the assay is more semiquantitative in nature. Despite its limitations, whether this assay is useful for the diagnosis of canine gastric disorders remains to be determined. PMID:15352539

A 25-year-old Hispanic female with a history of anemia, schizoaffective disorder, and psychosis was admitted for anemia associated with fatigue, weakness, shortness of breath, night sweats, weight loss, and abdominal and lower back pain for the past two months. On routine management, she was found to have a positive serum b-HCG of 80.4 (0–5 mIU/mL) but the patient denied any sexual activity in her life. During her admission, U/S of the pelvis was noncontributory. CT angiogram of the chest was significant for prominent mediastinal and hilar lymph nodes, diffusely thickened stomach suggesting gastric malignancy with multiple hypoenhancing lesions in the liver and diffuse lytic lesions in the spine and sacrum suspicious for metastatic disease. The MRI of the abdomen confirmed the CT angiogram findings. After these findings, EGD was performed which showed lesions in the antrum, body of the stomach, fundus, and cardia on the lesser curvature of the stomach body correlating with carcinoma. The biopsy was positive for Her2, b-HCG producing poorly differentiated gastric adenocarcinoma. Patient underwent one successful round of chemotherapy with Taxotene, Cisplatin, and 5-FU for Stage IV gastric adenocarcinoma. PMID:25349615

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

In the last 6 years, we have experienced 20 cancer patients who received home parenteral nutrition for terminal stage. The patients had 13 gastric cancers, 3 esophageal cancers and 5 others. The prognosis of upper G-I cancer is known to be poorer than that of colon cancer. The home care of our cases, the gastric cancer lasted 25 days on average, which was shorter than others. So the home care for patients in the terminal stage of gastric cancer is very short. Therefore we decide the home care for the terminal stage of gastric cancer as soon as possible. We conducted a questionnaire survey of our cases and family. We finally found that the most important thing is the safety of patient for the maintenance of home care. Our home care system is made up of a 3-way relationship among the patient, support system and doctor. The doctor is on call for the problems of the patient for 24 hours. Therefore, we believe that this system is comfortable for both the patient and family.

Pressure-sensitive dosage forms have been developed that are intended for pulsatile delivery of drugs to the proximal small intestine. The novel dosage forms are composed of insoluble shell and either a hard fat W32 or polyethylene glycol (PEG) 1000 core that are both liquidizing at body temperature. The release is triggered by predominant pressure waves such as contractions of the pylorus causing rupture of the shell and an immediate emptying of the liquefied filling containing the active ingredient. In consequence immediately after the trigger has been effective the total amount of the drug is intended to be available for absorption in the upper small intestine. Both core types were coated with a cellulose acetate film that creates a pressure-sensitive shell in which mechanical resistance is depending on the coating thickness. Results of the texture analysis confirmed a correlation between the polymer load of the coating and the mechanical resistance. The dissolution test performed under conditions of physiological meaningful mechanical stress showed that the drug release is triggered by pressure waves of ⩾300 mbar which are representing the maximal pressure occurring during the gastric emptying.

Endosonography was performed in diagnosing and staging pancreatic body and tail carcinoma in two patients. In the first case endoscopy, abdominal ultrasound, and computed tomography were nondiagnostic in diagnosing the origin of submucosal gastric abnormalities. Endosonography diagnosed a pancreatic tail carcinoma with submucosal gastric involvement, and this was confirmed by endosonographic-guided cytology. Fundus varices due to segmented splenic vein involvement were found. Surgery was not recommended due to the advanced disease. In the second case pancreatic body carcinoma was diagnosed by ERCP and computed tomography. Transcutaneous ultrasonographic-guided cytological puncture confirmed the diagnosis. Endosonography revealed additional information of segmental portal hypertensionmore » with fundic varices due to splenic vein involvement.

A group of 133 patients treated for bleeding peptic ulcer in our Department, is reviewed. Within several hours of admission, all patients underwent upper gastrointestinal tract gastroscopy and obliteration of the bleeding ulcer. Bleeding gastric ulcers were found in 41 patients, and duodenal ulcers in 92 patients. Patients were classified according to the Forrest scale: IA – 11 patients, IB – 49 patients, IIA – 35 patients, lIB – 40 patients. In 126 (94.7%) patients the bleeding was stopped, and 7 required urgent surgery: 3 patients with gastric ulcer underwent gastrectomy, and 4 with duodenal ulcer – truncal vagotomy with pyloroplasty and had the bleeding site underpinned. Fifty-five patients underwent elective surgery: gastrectomy and vagotomy (18 patients with gastric ulcer), highly selective vagotomy (25 patients with duodenal ulcer) and truncal vagotomy and pyloroplasty (12 patients with duodenal ulcer). None of the patients was observed to have recurrent bleeding. PMID:18493453

Preserving gastric function and improving quality of life (QOL) is the tendency of surgery for early gastric cancer. Function preserving gastrectomy (FPG) is applied to modify the extent of surgery and to achieve better quality of life at the premise of radical resection. Pylorus-preserving gastrectomy is the most favorable approach of FPG with oncological safety, which can improve nutritional status and QOL via preserving pylorus and vagal nerve. Proximal gastrectomy is widely accepted as FPG for early upper 1/3 gastric cancer. However, the most optimal way of anastomosis is not yet solved. Sentinel node navigation is currently the most accurate approach for intraoperative diagnosis of lymph node metastasis, which stimulates the development of many kinds of FPG procedures for individual treatment. Nevertheless, more efforts should be made to reduce false negative rate of sentinel node biopsy. Herein we discuss the valuation and prospect of FPG.

Several studies have reported an association between gastric atrophy and upper gastrointestinal cancers. Our aim was to summarise the available information and calculate the relative risks (RRs) associated with gastric atrophy for gastric cardia adenocarcinoma (GCA), oesophageal squamous cell carcinoma (OSCC), and oesophageal adenocarcinoma (OAC) by conducting a systematic review and meta-analysis. We searched the PubMed and ISI-Web of Science databases, as well as the reference lists of the relevant articles. Summary RRs and 95% confidence intervals (95% CI) were calculated using random-effects models for the association between gastric atrophy, defined histologically or by serum pepsinogen markers, and OSCC, OAC, and GCA. Eighteen articles were included in the meta-analysis; 13, 7, and 3 studies reported on GCA, OSCC, and OAC, respectively. The overall RRs (95% CI) for the three cancer types were: GCA, 2.89 (2.09-3.98); OSCC, 1.94 (1.48-2.55); OAC, 0.51 (0.19-1.37). Several subgroup analyses showed the robustness of the results. In the majority of the analyses, there was low to moderate heterogeneity. This study found two- to threefold increased risk of OSCC and GCA but a possible reduced risk of OAC in people with gastric atrophy. Further studies are needed to establish the association with OAC and causal association with OSCC, and mechanisms of the increased risk need to be investigated for GCA. © The Author 2010.

We assessed whether adherent gastric mucous to biopsy forceps instead of biopsy samples was suitable for the diagnosis of H. pylori infection. We confirmed the PCR methods to improve the diagnosis of H. pylori infection and clarithromycin (CAM) susceptibility. Gastric mucous was obtained by gently scraping gastric mucosa using biopsy forceps in patients undergoing upper gastrointestinal (GI) endoscopy for PCR and rapid urease test (RUT). DNA was extracted from gastric mucous present within the gel of RUT. H. pylori status and CAM susceptibility were evaluated using H. pylori-specific PCR amplification for 23S rRNA using 4 different primer sets and 16S rRNA. H. pylori positive was defined as two of the three tests (serum antibody, histology, and RUT or PCR) were positive. CAM susceptibility was evaluated by point mutations (A 2142G and A 2143G of 23S rRNA). Samples taken from 494 subjects were evaluated: 300 H. pylori-positive patients and 194 negative patients. The results of PCR using DNA extracted from gastric mucous present within the RUT gel were consistent with those within water. The accuracy of 23S rRNA PCR for H. pylori detection using RUT samples was superior to the other tests. The frequency of CAM resistance was 38.9%, and eradication rate was 91.3% in the patients with wild-type and 47.0% in the patients with the mutant strains. Adherent gastric mucous to biopsy forceps in RUT gel can be used for molecular testing to confirm the diagnosis of H. pylori infection and for CAM susceptibility. © 2016 John Wiley & Sons Ltd.

Laparoscopic single anastomosis gastric bypass (SAGB) is increasingly performed for morbidly obese patients. This pilot study aims primarily at evaluating the incidence of bile gastritis after SAGB. The occurrence of reflux oesophagitis and reflux symptoms were also assessed. This study included 20 patients having no reflux symptoms. All patients underwent a SAGB as a primary bariatric procedure by a single surgeon. Patients included consented to have an upper GI endoscopy done at 6 months postoperatively. Gastric aspirate was sent for bilirubin level assessment. Gastric and esophageal biopsies were submitted for histopathology and campylobacter-like organism (CLO) test. In our study, the rate of bile gastritis was 30%. In 18 patients, the level of bilirubin in gastric aspirate seems to be related to the degree of mucosal inflammation. The remaining two patients had microscopic moderate to severe gastritis with normal aspirate bilirubin level. Two patients with bilirubin level in aspirate more than 20 mg/dl had severe oesophagitis, gastritis with erosions, and metaplasia. Relationship between bilirubin level and histopathological findings of gastric biopsy examination was statistically significant with a P value of 0.001. The incidence of bile gastritis in this cohort is higher than reported in the literature, and this may be worrying. The correlation between endoscopic findings and patients' symptoms is poor. Bilirubin level and pH in aspirate might be useful tools to confirm alkaline reflux. Its level might help to choose candidates for revision surgery after SAGB. This needs further validation with larger sample size.

We have previously shown promising results 2 years after Roux-en-Y gastric bypass surgery, within the Adolescence Morbid Obesity Surgery study (AMOS). The aim of the current study was to describe the 2-year outcome in cardiorespiratory fitness, body composition, and functional capacity in the Stockholm subset of the AMOS study. Forty-one adolescents (10 male, 31 female, age 14-18 years, body mass index 35-69 kg·m -2 ) were included. In addition to anthropometric measurements, participants performed a submaximal bicycle test, 6-min walk test, dual-energy X-ray absorptiometry, and a short interview at baseline, 1 and 2 years after surgery. Relative improvements in maximal oxygen consumption (VO 2 max) per kilogram body mass (+62 %) and per kilogram fat-free mass (+21 %), as well as walking distance (+13 %) were observed after 1 year, and persisted 2 years after surgery. Despite a reduction of fat-free mass (-15 %), absolute VO 2 max was maintained across the full group (+8 %, p = ns) and significantly increased in non-smokers. Body mass and fat mass were significantly decreased (-45.4 and -33.3 kg, respectively). Self-reported physical activity was significantly increased, and pain associated with movement was reduced. In adolescents with obesity, Roux-en-Y gastric bypass improved VO 2 max more than could be explained by fat mass loss alone. In combination with improved functional capacity and body composition, these results suggest that surgery in adolescence might add specific benefits of importance for future health.

Human gastric diseases have shown significant changes in the activity and expression of superoxide dismutase (SOD) isoforms. The aim of this study was to detect Mn-SOD activity and expression in the tissue of gastric mucosa, primarily in chronic gastritis (immunohistochemical Helicobacter pylori-negative gastritis, without other pathohistological changes) and to evaluate their possible connection with pathohistological diagnosis. We examined 51 consecutive outpatients undergoing endoscopy for upper gastrointestinal symptoms. Patients were classified based on their histopathological examinations and divided into three groups: 51 patients (archive samples between 2004-2009) with chronic immunohistochemical Helicobacter pylori-negative gastritis (mononuclear cells infiltration were graded as absent, moderate, severe) divided into three groups. Severity of gastritis was graded according to the updated Sydney system. Gastric tissue samples were used to determine the expression of Mn-SOD with anti-Mn-SOD Ab immunohistochemically. The Mn-SOD expression was more frequently present in specimens with severe and moderate inflammation of gastric mucosa than in those with normal mucosa. In patients with normal histological finding, positive immunoreactivity of Mn-SOD was not found. Our results determine the changes in Mn-SOD expression occurring in the normal gastric mucosa that had undergone changes in the intensity of chronic inflammatory infiltrates in the lamina propria. © 2016 APMIS.

To evaluate gastric emptying in anorexia nervosa patients, 26 patients (17 females, two males, ranging in age from 13 to 40 yr) with upper GI symptoms ingested 150-200 microCi (/sup 99m/Tc)triethelenetetraamine polysterene resin in cereal and were imaged in the supine position. Data were accumulated at 5 min intervals to obtain the gastric emptying time (GET). The results of the studies were divided into three categories: prolonged, 13 patients; rapid, 11; and normal 3. Twelve of 13 patients with prolonged GET were given 10 mg metoclopramide i.v. injections; nine of the 12 patients had a good response and three hadmore » no response. Five of the nine patients underwent metoclopramide therapy and four of the patients showed benefit from the therapy. One patient discontinued metoclopramide therapy because of somnolence. Although all patients had subjective symptoms of gastric dysfunction, our results indicated only 50% had objectively prolonged GET, and another 50% showed normal or even rapid GET. Therefore, this radionuclide study enables quantitatively objective documentation of gastric emptying, separation of those patients with rapid or normal GET from those with prolonged GET, thereby avoiding the possible side effects from metoclopramide medication, and prediction of effectiveness of metoclopramide therapy in patients with prolonged GET.« less

A Combined Methodology to Eliminate Artifacts in Multichannel Electrogastrogram Based on Independent Component Analysis and Ensemble Empirical Mode Decomposition.

Cutaneous measurements of electrogastrogram (EGG) signals are heavily contaminated by artifacts due to cardiac activity, breathing, motion artifacts, and electrode drifts whose effective elimination remains an open problem. A common methodology is proposed by combining independent component analysis (ICA) and ensemble empirical mode decomposition (EEMD) to denoise gastric slow-wave signals in multichannel EGG data. Sixteen electrodes are fixed over the upper abdomen to measure the EGG signals under three gastric conditions, namely, preprandial, postprandial immediately, and postprandial 2 h after food for three healthy subjects and a subject with a gastric disorder. Instantaneous frequencies of intrinsic mode functions that are obtained by applying the EEMD technique are analyzed to individually identify and remove each of the artifacts. A critical investigation on the proposed ICA-EEMD method reveals its ability to provide a higher attenuation of artifacts and lower distortion than those obtained by the ICA-EMD method and conventional techniques, like bandpass and adaptive filtering. Characteristic changes in the slow-wave frequencies across the three gastric conditions could be determined from the denoised signals for all the cases. The results therefore encourage the use of the EEMD-based technique for denoising gastric signals to be used in clinical practice.

Gastric bypass leads to the remission of type 2 diabetes independently of weight loss. Our hypothesis is that changes in bile flow due to the altered anatomy may partly explain the metabolic outcomes of the operation. We prospectively studied 12 patients undergoing gastric bypass and six patients undergoing gastric banding over a 6-wk period. Plasma fibroblast growth factor (FGF)19, stimulated by bile acid absorption in the terminal ileum, and plasma bile acids were measured. In canine and rodent models, we investigated changes in the gut hormone response after altered bile flow. FGF19 and total plasma bile acids levels increased after gastric bypass compared with no change after gastric banding. In the canine model, both food and bile, on their own, stimulated satiety gut hormone responses. However, when combined, the response was doubled. In rats, drainage of endogenous bile into the terminal ileum was associated with an enhanced satiety gut hormone response, reduced food intake, and lower body weight. In conclusion, after gastric bypass, bile flow is altered, leading to increased plasma bile acids, FGF19, incretin. and satiety gut hormone concentrations. Elucidating the mechanism of action of gastric bypass surgery may lead to novel treatments for type 2 diabetes. PMID:22673227

The effect of prolonged administration of all-trans-retinoic acid (RA) on sodium chloride-enhanced gastric carcinogenesis induced by N-methyl-N'-nitro-N-nitrosoguanidine, and the labelling and apoptotic indices and immunoreactivity of transforming growth factor (TGF) alpha in the gastric cancers was investigated in Wistar rats. After 25 weeks of carcinogen treatment, the rats were given chow pellets containing 10% sodium chloride and subcutaneous injections of RA at doses of 0.75 or 1.5 mg kg(-1) body weight every other day. In week 52, oral supplementation with sodium chloride significantly increased the incidence of gastric cancers compared with the untreated controls. Long-term administration of RA at both doses significantly reduced the incidence of gastric cancers, which was enhanced by oral administration of sodium chloride. RA at both doses significantly decreased the labelling index and TGF-alpha immunoreactivity of gastric cancers, which were enhanced by administration of sodium chloride, and significantly increased the apoptotic index of cancers, which was lowered by administration of sodium chloride. These findings suggest that RA attenuates gastric carcinogenesis, enhanced by sodium chloride, by increasing apoptosis, decreasing DNA synthesis, and reducing TGF-alpha expression in gastric cancers.

Advances in molecular biomarkers for gastric cancer: miRNAs as emerging novel cancer markers.

Carcinoma of the stomach is one of the most prevalent cancer types in the world. Although the incidence of gastric cancer is declining, the outcomes of gastric cancer patients remain dismal because of the lack of effective biomarkers to detect early gastric cancer. Modern biomedical research has explored many potential gastric cancer biomarker genes by utilising serum protein antigens, oncogenic genes or gene families through improving molecular biological technologies, such as microarray, RNA-Seq and the like. Recently, the small noncoding microRNAs (miRNAs) have been suggested to be critical regulators in the oncogenesis pathways and to serve as useful clinical biomarkers. This new class of biomarkers is emerging as a novel molecule for cancer diagnosis and prognosis, including gastric cancer. By translational suppression of target genes, miRNAs play a significant role in the gastric cancer cell physiology and tumour progression. There are potential implications of previously discovered gastric cancer molecular biomarkers and their expression modulations by respective miRNAs. Therefore, many miRNAs are found to play oncogenic roles or tumour-suppressing functions in human cancers. With the surprising stability of miRNAs in tissues, serum or other body fluids, miRNAs have emerged as a new type of cancer biomarker with immeasurable clinical potential.

Effect of pre-treatment with hot water extract of marine brown alga Sargassum polycystum C.Ag. (100 mg/kg body wt, orally for period of 15 days) on HCl-ethanol (150 mM of HCl-ethanol mixture containing 0.15 N HCl in 70% v/v ethanol given orally) induced gastric mucosal injury in rats was examined with respect to lipid peroxides, antioxidant enzyme status, acid/pepsin and glycoproteins in the gastric mucosa. The levels of lipid peroxides of gastric mucosa and volume, acidity of the gastric juice were increased with decreased levels of antioxidant enzymes and glycoproteins were observed in HCl-ethanol induced rats. The rats pre-treated with seaweed extract prior to HCl-ethanol induction reversed the depleted levels of antioxidant enzymes and reduced the elevated levels of lipid peroxides when compared with HCl-ethanol induced rats. The levels of glycoproteins and alterations in the gastric juice were also maintained at near normal levels in rats pre-treated with seaweed extract. The rats given seaweed extract alone did not show any toxicity, which was confirmed by histopathological studies. These results suggest that the seaweed extract contains some anti-ulcer agents, which may maintain the volume/acidity of gastric juice and improve the gastric mucosa antioxidant defense system against HCl-ethanol induced gastric mucosal injury in rats.

A 4 yr old, castrated male dachshund was presented for lethargy, restlessness, a "hunched" posture, and a painful abdomen. A gastric foreign body had been surgically removed 24 mo previously. Exploratory celiotomy revealed a devitalized segment of jejunum with twisted mesentery. Several adhesions and fibrous bands were present within the abdomen, presumptively from the previous gastric foreign body surgery. Histopathology determined that a fibrous tissue band caused entrapment of the segment of intestine and its mesentery resulting in volvulus and ischemic necrosis of the intestine. This case is unique because it involved a focal area of the jejunum that was incarcerated in fibrous adhesions.

A 63-year-old woman was referred to our hospital for further examination because of an incidental finding of early gastric cancer. Endoscopic submucosal dissection (ESD) was successfully performed for complete resection of the tumor. On the first post-ESD day, the patient suddenly complained of abdominal pain after an episode of vomiting. Abdominal computed tomography (CT) showed delayed perforation after ESD. The patient was conservatively treated with an intravenous proton pump inhibitor and antibiotics. On the fifth post-ESD day, CT revealed a gastric wall abscess in the gastric body. Gastroscopy revealed a gastric fistula at the edge of the post-ESD ulcer, and pus was found flowing into the stomach. An intradrainage stent and an extradrainage nasocystic catheter were successfully inserted into the abscess for endoscopic transgastric drainage. After the procedure, the clinical symptoms and laboratory test results improved quickly. Two months later, a follow-up CT scan showed no collection of pus. Consequently, the intradrainage stent was removed. Although the gastric wall abscess recurred 2 wk after stent removal, it recovered soon after endoscopic transgastric drainage. Finally, after stent removal and oral antibiotic treatment for 1 mo, no recurrence of the gastric wall abscess was found. PMID:24574787

Background The psychological symptoms associated with binge eating disorder (BED) have been well documented. However, the physical symptoms associated with BED have not been explored. Gastrointestinal (GI) symptoms such as heartburn and diarrhea are more prevalent in obese adults, but the associations remain unexplained. Patients with bulimia have increased gastric capacity. The objective of the study was to examine if the severity of binge eating episodes would be associated with upper and lower GI symptoms. Methods Population-based survey of community residents through a mailed questionnaire measuring GI symptoms, frequency of binge eating episodes and physical activity level. The association of GI symptoms with frequency of binge eating episodes was assessed using logistic regression models adjusting for age, gender, body mass index (BMI) and physical activity level. Results In 4096 subjects, BED was present in 6.1%. After adjusting for BMI, age, gender, race, diabetes mellitus, socioeconomic status and physical activity level, BED was independently associated with the following upper GI symptoms: acid regurgitation (P < 0.001), heartburn (P < 0.001), dysphagia (P < 0.001), bloating (P < 0.001) and upper abdominal pain (P < 0.001). BED was also associated with the following lower GI symptoms: diarrhea (P < 0.001), urgency (P < 0.001), constipation (P < 0.01) and feeling of anal blockage (P = 0.001). Conclusion BED appears to be associated with the experience of both upper and lower GI symptoms in the general population, independent of the level of obesity. The relationship between increased GI symptoms and physiological responses to increased volume and calorie loads, nutritional selections and rapidity of food ingestion in individuals with BED deserves further study.

Gastroduodenal tuberculosis is a rare location of abdominal tuberculosis. It usually occurs secondary to pulmonary tuberculosis. We report a case of a 63-year-old woman admitted to the referral center for symptoms of upper gastrointestinal obstruction caused by ulcerohypertrophic antroduodenal tuberculosis. The lesion was misdiagnosed as malignancy at endoscopy. Even at surgery, the lesion was considered gastric cancer and imposed an oncologic resection. The diagnosis was established in the presence of giant-cell granulomas with caseating necrosis in the surgical resected specimens. In our case, the rare gastroduodenal location of abdominal tuberculosis occurred as primary tuberculosis, in the absence of other identifiable locations.

Although preoperative fluid intake 2 hours before anesthesia is generally considered safe, there are concerns about delayed gastric emptying in obese subjects. In this study, the gastric fluid volume (GFV) change in morbidly obese subjects was investigated after ingesting an oral rehydration solution (ORS) and then compared with that in nonobese subjects. GFV change over time after the ingestion of 500 mL of ORS containing 2.5% carbohydrate (OS-1) was measured in 10 morbidly obese subjects (body mass index [BMI], >35) scheduled for bariatric surgery and 10 nonobese (BMI, 19-24) using magnetic resonance imaging. After 9 hours of fasting, magnetic resonance imaging scans were performed at preingestion, 0 min (just after ingestion), and every 30 minutes up to 120 minutes. GFV values were compared between morbidly obese and control groups and also between preingestion and postingestion time points. The morbidly obese group had a significantly higher body weight and BMI than the control group (mean body weight and BMI in morbidly obese, 129.6 kg and 46.3 kg/m, respectively; control, 59.5 kg and 21.6 kg/m, respectively). GFV was significantly higher in the morbidly obese subjects compared with the control group at preingestion (73 ± 30.8 mL vs 31 ± 19.9 mL, P = .001) and at 0 minutes after ingestion (561 ± 30.8 mL vs 486 ± 42.8 mL; P < .001). GFV declined rapidly in both groups and reached fasting baseline levels by 120 minutes (morbidly obese, 50 ± 29.5 mL; control, 30 ± 11.6 mL). A significant correlation was observed between preingestion residual GFV and body weight (r = .66; P = .001). Morbidly obese subjects have a higher residual gastric volume after 9 hours of fasting compared with subjects with a normal BMI. However, no differences were observed in gastric emptying after ORS ingestion in the 2 populations, and GFVs reached baseline within 2 hours after ORS ingestion. Further studies are required to confirm whether the preoperative fasting and fluid management that are recommended for nonobese patients could also be applied to morbidly obese patients.

Several studies concerning the relationships between gastroesophageal reflux (GOR), gastric emptying and esophageal motility are available. So far, results have been contradictory. The purpose of this work was to study gastric emptying in patients with GOR; to search for simultaneous esophageal motility disorders and to specify their type and frequency; to establish a potential relationship between motor disorders of the esophagus and the stomach in these patients. Thirty-two consecutive patients were selected according to clinical criteria, i.e. presence of at least two of the three characteristic symptoms of GOR, and the data of a three-hour post-prandial pH-metry. Gastric stasis related clinical manifestations (nausea, post-prandial vomiting, sensation of abdominal distension or of post-prandial epigastric fullness) were also searched for in all patients. A gastroscopy allowed to score esophagitis in each case. All patients, including adult controls underwent an esophageal manometry as well as a radionuclide determination of gastric emptying, after isotopic labelling of the solid (S) and liquid (L) phases of a test meal. The results showed that there was no significant modification of gastric emptying of the S and L phases of the meal in the group of patients with GOR whatever the intensity of the reflux, judged on the pH-metry results and the endoscopic data. Thus the average time of gastric half-emptying of S and L was respectively 115 and 52 min for the patients vs 111 and 51 min for the control group. As well, no correlation was found between the gastric emptying parameters and the presence or absence of clinical signs of gastric stasis or the amplitude of esophageal contraction waves. On an individual basis, two patients showed a significant decrease in gastric emptying of either the S or L phases without any attendant modification in the kinetics of the other. These results suggest that, in the adult, gastric emptying cannot be considered to be a determining factor of GOR and there are no diffuse motility disorders of the upper digestive tract during this illness.

Limited data are available on the relative pharmacokinetics and pharmacodynamics of different omeprazole formulations. To compare pharmacokinetic and pharmacodynamic effects of a novel omeprazole formulation against a currently registered product. Masked 2 period, 2 treatment crossover. Twelve clinically healthy horses were studied over two 6-day treatment periods. Horses were randomly assigned to receive a novel omeprazole paste (Ulcershield: ULS) or a currently registered reference omeprazole product (OMO). Gastric pH was measured continuously for 10 h on the day prior to commencing treatment (Day -1) and after 6 days of oral treatment (Day 5) using in situ antimony pH probes within an indwelling nasogastric tube. Plasma pharmacokinetics were determined on Days 0 and 6. Treatment significantly (P<0.005) increased gastric pH on Day 5, compared to results obtained prior to treatment (Day -1) and there was no significant difference between products (P = 0.773). Similarly, comparison of median hourly gastric pH (P = 0.593), mean gastric pH (P = 0.154), percentage time pH<4 (P = 0.259) and area under the time-gastric pH response curve (P = 0.734) did not discriminate between products. Both treatments resulted in significantly lower gastric ulcer severity scores (both P = 0.004), with no difference between treatments (P = 0.688). Comparison of mean log area under time-plasma concentration curves demonstrated that, although the lower limit of the 90% confidence interval was within the -20% limit for bioequivalence, the upper limit was exceeded, suggesting that the test product could have greater bioavailability than the reference product. The small sample size, large interhorse plasma omeprazole concentrations, and low bioavailability of omeprazole impacted the sensitivity of the bioequivalence analysis. ULS matched or slightly exceeded OMO plasma concentrations. Both products resulted in equivalent increases in gastric pH, gastric pH profiles and decrease in gastric ulcer scores. Thus, ULS was pharmacodynamically equivalent to OMO and was associated with an equivalent beneficial effect on gastric squamous mucosal ulceration. © 2017 EVJ Ltd.

To validate veterans affairs (VA) administrative data for the diagnosis of nonsteroidal anti-inflammatory drug (NSAID)-related upper gastrointestinal events (UGIE) and to develop a diagnostic algorithm. A retrospective study of veterans prescribed an NSAID as identified from the national pharmacy database merged with in-patient and out-patient data, followed by primary chart abstraction. Contingency tables were constructed to allow comparison with a random sample of patients prescribed an NSAID, but without UGIE. Multivariable logistic regression analysis was used to derive a predictive algorithm. Once derived, the algorithm was validated in a separate cohort of veterans. Of 906 patients, 606 had a diagnostic code for UGIE; 300 were a random subsample of 11 744 patients (control). Only 161 had a confirmed UGIE. The positive predictive value (PPV) of diagnostic codes was poor, but improved from 27% to 51% with the addition of endoscopic procedural codes. The strongest predictors of UGIE were an in-patient ICD-9 code for gastric ulcer, duodenal ulcer and haemorrhage combined with upper endoscopy. This algorithm had a PPV of 73% when limited to patients >or=65 years (c-statistic 0.79). Validation of the algorithm revealed a PPV of 80% among patients with an overlapping NSAID prescription. NSAID-related UGIE can be assessed using VA administrative data. The optimal algorithm includes an in-patient ICD-9 code for gastric or duodenal ulcer and gastrointestinal bleeding combined with a procedural code for upper endoscopy.

The aim was to assess the incidence of endoscopic findings based on the indication of the procedures in upper/lower endoscopies, and measuring quality indicators of colonoscopies at the 1st Department of Medicine, Semmelweis University, Budapest. Data of 2987 patients (male/female:1361/1626, mean age: 60.7 years(y), SD: 16.7y) between 01.01.2010 and 31.12.2011 were analyzed. Both inpatient and outpatient records were collected. Incidence of peptic ulcer disease, esophageal varices, gastric polyps and gastric cancer were 10.8%, 4.5%, 6.1%, 2.9% in upper endoscopies, respectively. In colonoscopies colorectal polyps, diverticulosis, colorectal cancer and IBD were found in 29.9%, 22.4%, 6.9%, 9.7%, respectively. In patients having upper endoscopy with GI bleeding indication, older age (p<0.001), male gender (p<0.001, OR: 1.64), acenocoumarol/heparin use (p<0,001, peptic ulcers and esophageal varices were more frequent (p<0.001, OR: 2.83 and p<0.001, OR: 2.79), while in colonoscopies colorectal cancer had higher incidence (p<0.001, OR:3.27). 81% of colonoscopies were complete. Causes of incomplete procedures were ineffective bowel preparation (38.2%), technical difficulties (25.1%) and strictures (20.5%). The endoscopic findings and quality indicators (adenoma detection rate, coecal intubation rate) were in line with that reported in published series. Orv. Hetil., 2016, 157(52), 2074-2081.

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.

Purpose: The present study investigated the effects of high-intensity intermittent training (HIIT) on lower- and upper-body graded exercise and high-intensity intermittent exercise (HIIE, four Wingate bouts) performance, and on physiological and muscle damage markers responses in judo athletes. Methods: Thirty-five subjects were randomly allocated to a control group (n = 8) or to one of the following HIIT groups (n = 9 for each) and tested pre- and post-four weeks (2 training d·wk−1): (1) lower-body cycle-ergometer; (2) upper-body cycle-ergometer; (3) uchi-komi (judo technique entrance). All HIIT were constituted by two blocks of 10 sets of 20 s of all out effort interspersed by 10 s set intervals and 5-min between blocks. Results: For the upper-body group there was an increase in maximal aerobic power in graded upper-body exercise test (12.3%). The lower-body group increased power at onset blood lactate in graded upper-body exercise test (22.1%). The uchi-komi group increased peak power in upper- (16.7%) and lower-body (8.5%), while the lower-body group increased lower-body mean power (14.2%) during the HIIE. There was a decrease in the delta blood lactate for the uchi-komi training group and in the third and fourth bouts for the upper-body training group. Training induced testosterone-cortisol ratio increased in the lower-body HIIE for the lower-body (14.9%) and uchi-komi (61.4%) training groups. Conclusion: Thus, short-duration low-volume HIIT added to regular judo training was able to increase upper-body aerobic power, lower- and upper-body HIIE performance. PMID:27445856

To evaluate the long-term remission rates of type 2 diabetes mellitus and associated comorbidities after gastric bypass surgery in a complete cohort, in a real-life clinic setting. A retrospective study of all consecutive patients with type 2 diabetes mellitus who underwent gastric bypass at a Veterans Affairs Medical Center from 2003 to 2010. The main outcome was remission of type 2 diabetes mellitus defined as HbA1c <6.5% (49 mmol/mol) without diabetic medication usage. Secondary outcomes were remission of hypertension and hyperlipidemia, weight loss, and long-term complications four years post-gastric bypass. Eighty-four patients with type 2 diabetes mellitus underwent gastric bypass. Four-year follow-up data were available for 92% (77/84) of patients. The patients (73% male; mean age 54 years) had a mean body mass index of 49 kg/m 2  ± 8.3. Hypertension and hyperlipidemia prevalence were 92% and 85%, respectively. The mean total body weight decrease over four years was 35 kg ± 21. Remission of type 2 diabetes mellitus occurred in 15% at 6 months and 49% four years after surgery. Diabetes remission was more likely (OR 3.2; 95% confidence interval 1.2-9.7) in patients not using insulin at baseline. Remission rates were 12% (9/74) for hypertension and 16% (11/68) for hyperlipidemia. Long-term surgical complications included reoperation (11%), incisional hernia (10%) and anastomotic ulcer (10%). Forty-four percent of patients had one or more nutritional complications. The metabolic effects of gastric bypass are significant and durable for at least four years, even in a predominantly male cohort and real-life clinical setting. Published by Elsevier B.V.

Patients with symptoms suggestive of gastroparesis exhibit several symptoms, such as epigastric pain, postprandial fullness, bloating and regurgitation. It is uncertain if such symptoms reflect underlying oesophageal motor disorder. To examine whether patients with epigastric pain and postprandial distress syndrome suggestive of functional dyspepsia and/or gastroparesis also have concomitant oesophageal motility abnormalities and, if so, whether there are any associations between these disturbances. In this retrospective cohort study, consecutive patients with functional gastrointestinal symptoms suggestive of gastric neuromuscular dysfunction (gastroparesis or functional dyspepsia) underwent clinical assessment, gastric scintigraphy, oesophageal high-resolution manometry and ambulatory pH monitoring using standard protocols. We studied 61 patients with various functional upper gastrointestinal symptoms who underwent gastric scintigraphy, oesophageal high-resolution manometry and ambulatory pH monitoring. Forty-four patients exhibited gastroparesis by gastric scintigraphy. Oesophageal motility disorders were found in 68% and 42% of patients with or without scintigraphic evidence of gastroparesis respectively, suggesting of overlapping gastric and oesophageal neuromuscular disorder. Forty-three per cent of patients with gastroparesis had abnormal oesophageal acid exposure with mean % pH <4.0 of 7.5 in contrast to 38% of those symptomatic controls with normal gastric emptying, with mean %pH <4.0 of 5.4 (NS). Symptoms of epigastric pain, heartburn/regurgitation, bloating, nausea, vomiting, dysphagia, belching and weight loss could not distinguish patients with or without gastroparesis, although weight loss was significantly more prevalent and severe (p<0.002) in patients with gastroparesis. There was no relationship between oesophageal symptoms and motor or pH abnormalities in either groups. Irrespective of gastric emptying delay by scintigraphy, patients with symptoms suggestive of gastric neuromuscular dysfunction have a high prevalence of oesophageal motor disorder and pathological oesophageal acid exposure that may contribute to their symptoms and may require therapy. High-resolution oesophageal manometry and pH monitoring are non-invasive and potentially useful in the assessment and management of these patients.

To find out the recurrence of esophageal varices, evolution of gastric varices, portal hypertensive gastropathy (PHG) and risk of rebleeding following esophageal variceal eradication. Between 1992 and 2002, children with extrahepatic portal venous obstruction (EHPVO) and bleeding from esophageal varices received endoscopic injection sclerotherapy until eradication. Surveillance endoscopy was performed initially at 3 months and subsequently at intervals of 6 months to one year to detect esophageal and gastric varices, and PHG. Gastric varices were classified as gastroesophageal (GOV) or isolated gastric varices (IGV). Gastroesophageal varices included types GOV1 and GOV2 that extend along lesser and greater curvatures respectively. Patients who had recurrence of bleeding were evaluated by emergency upper gastrointestinal endoscopy. 163 of 183 children who achieved esophageal variceal eradication were evaluated. Esophageal varices recurred in 40% cases. Primary gastric varices (before sclerotherapy) were seen in 61% cases [GOV 98% (83% GOV1, 15% GOV2) and IGV 2%] and secondary (after sclerotherapy) in 28% [GOV 71% (47% GOV1, 24% GOV2) and IGV 29%]. Secondary gastric varices were distributed as 20% GOV1, 42% GOV2 and 87% IGV. Frequency of gastric varices before sclerotherapy and at the last follow up showed decrease in GOV1 from 82 to 56 (P = 0.02), increase in GOV2 from 15 to 23 and increase in IGV from 2 to 15 (P < 0.001). PHG increased in frequency from 12% to 41% (P < 0.001) and severity from one patient to 12 (P < 0.001). Eleven cases had rebleeding from gastric varices (5 GOV1, 4 GOV2 and 2 IGV). Following esophageal variceal eradication in children with EHPVO a significant decrease in GOV1, increase in IGV and increased frequency and severity of PHG takes place. Small rebleeding risk persists from gastric varices irrespective of the type.

Antithrombotic drugs, such as low-dose aspirin (LDA) and clopidogrel, can cause upper gastrointestinal complications. The goal of the present study was to investigate whether a mucosal-protective agent, rebamipide, could prevent gastric mucosal injuries induced by LDA with or without clopidogrel in healthy subjects. A randomized, double-blind, placebo-controlled trial was performed with 32 healthy male volunteers. Subjects were randomly assigned to a 14-day course of one of the following regimens: group A, placebo (tid) + LDA; group B, rebamipide (100 mg tid) + LDA (100 mg once-daily); group C, placebo + LDA + clopidogrel (75 mg once-daily); or group D, rebamipide + LDA + clopidogrel. The grade of gastric mucosal injuries was evaluated by esophagogastroduodenoscopy before and after dosing (on day 0 and day 14), and the grade of gastric mucosal injury was assessed according to the modified Lanza score. Subjective symptoms were assessed using the Gastrointestinal Symptom Rating Scale (GSRS). A rapid urease test was performed on day 0, and blood tests were performed on day 0 and day 14. Rebamipide significantly inhibited gastric mucosal injury induced by LDA alone or by LDA plus clopidogrel when compared with placebo in healthy subjects. GSRS score and hemoglobin level were not significantly different among the four groups. Rebamipide is useful for the primary prevention of gastric mucosal injury induced by LDA alone or by LDA plus clopidogrel in healthy subjects.

Background/Aims There are no available data about the relationship between ghrelin gene genotypes and early phase of gastric emptying in functional dyspepsia (FD) as defined by Rome III classification. Methods We enrolled 74 patients presenting with typical symptoms of FD and 64 healthy volunteers. Gastric motility was evaluated using the 13C-acetate breath test. We used Rome III criteria to evaluate upper abdominal symptoms and self-rating questionnaires for depression (SRQ-D) scores to determine status of depression. The Arg51Gln (346G>A), preproghrelin (3056T>C), Leu72Met (408C>A), Gln90Leu (3412T>A) and G-protein β3 (825C>T) polymorphisms were analyzed in the DNA from blood samples of enrolled subjects. Genotyping was performed by polymerase chain reaction. Results There was a significant relationship between the Gln90Leu3412 genotype and SRQ-D score in FD patients (P = 0.009). Area under the curve at 15 minutes (AUC15) value was significantly associated with the Leu72Met408 genotype (P = 0.015) but not with entire gastric emptying. Conclusions The Leu72Met (408C>A) single nucleotide polymorphism was significantly associated with early phase of gastric emptying in FD patients. Further studies will be necessary to clarify the association between ghrelin gene single nucleotide polymorphisms and early phase of gastric emptying in FD patients. PMID:25540946

Studies assessing the effect and mechanism of probiotics on diseases of the upper gastrointestinal tract (GI) including gastric ulcers are limited despite extensive work and promising results of this therapeutic option for other GI diseases. In this study, we investigated the mechanisms by which the probiotic mixture VSL#3 (a mixture of eight probiotic bacteria including Lactobacilli, Bifidobacteria and Streptococcus species) heals acetic acid induced gastric ulcer in rats. VSL#3 was administered orally at low (6×109 bacteria) or high (1.2×1010 bacteria) dosages from day 3 after ulcer induction for 14 consecutive days. VSL#3 treatments significantly enhanced gastric ulcer healing in a dose-dependent manner. To assess the mechanism(s) whereby VSL#3 exerted its protective effects, we quantified the gene expression of several pro-inflammatory cytokines, protein and expression of stomach mucin-Muc5ac, regulatory cytokine-IL-10, COX-2 and various growth factors. Of all the components examined, only expression and protein production of VEGF was increased 332-fold on day 7 in the ulcerated tissues of animals treated with VSL#3. Predictably, animals treated with VEGF neutralizing antibody significantly delayed gastric ulcer healing in VSL#3 treated animals. This is the first report to demonstrate high efficacy of the probiotic mixture VSL#3 in enhancing gastric ulcer healing. Probiotic efficacy was effective at higher concentrations of VSL#3 by specifically increasing the expression and production of angiogenesis promoting growth factors, primarily VEGF. PMID:23484048

To evaluate influence of laparoscopic gastric banding (LGB) on quality of life (QOL) in patients with morbid obesity. Laparoscopic adjustable gastric banding is a popular bariatric operation in Europe. The objectives of surgical therapy in patients with morbid obesity are reduction of body weight, and a positive influence on the obesity-related comorbidity as well the concomitant psychologic and social restrictions of these patients. In a prospective clinical trial, development of the individual patient QOL was analyzed, after LGB in patients with morbid obesity. From October 1999 to January 2001, 152 patients [119 women, 33 men, mean age 38.4 y (range 24 to 62), mean body mass index 44.3 (range 38 to 63)] underwent evaluation for LGB according the following protocol: history of obesity; concise counseling of patients and relative on nonsurgical treatment alternatives, risk of surgery, psychologic testing, questionnaire for eating habits, necessity of lifestyle change after surgery; medical evaluation including endocrinologic and nutritionist work-up, upper GI endoscopy, evaluation of QOL using the Gastro Intestinal Quality of Life Index (GIQLI). Decision for surgery was a multidisciplinary consensus. This group was follow-up at least 2 years, focusing on weight loss and QOL. Mean operative time was 82 minutes; mean hospital stay was 2.3 days and the mean follow-up period was 34 months. The BMI dropped from 44.3 to 29.6 kg/m and all comorbid conditions improved markedly: diabetes melitus resolved in 71% of the patients, hypertension in 33%, and sleep apnea in 90%. However, 26 patients (17%) had late complications requiring reoperation. Preoperative global GIQLI score was 95 (range 56 to 140), significant different of the healthy volunteers score (120) (70 to 140) P < 0.001. Correlated with weight loss (percentage loss of overweight and BMI), the global score of the group increased to 100 at 3 months, 104 at 6, 111 at 1 year to reach 119 at 2 years which is no significant different of healthy patients. Analyzing the subscale, physical condition, emotional status, and social integration increased significantly (P < 0.001) from preoperative to end of follow-up. Digestive symptoms were not modified. In case of failure of the procedure (10.5%) global Giqli score is not modified. Patients who have required successful revisional surgery for late complications (6.5%) have an excellent QOL outcome that are not different from the whole group. Together with a satisfactory reduction of the excess overweight, laparoscopic gastric banding may lead in a carefully selected population of patients with morbid obesity to a significant improvement of patient QOL, in at least 2 years follow-up.

Portal annular pancreas is a rare anatomic variation, where the uncinated process of the pancreas connects with the dorsal pancreas and the pancreas tissue encases the portal vein (PV), superior mesenteric vein (SMV) or splenic vein (SV). Malignancies are quite uncommon in the patients, who have an annular pancreas especially portal annular pancreas. Ectopic common hepatic artery and absence of the celiac trunk (CT) are the other infrequent abnormalities. A 74-year-old man suffered from upper abdominal and back pain. Contrast enhanced computed tomography indicated a low-density mass in the body of the pancreas. Pathological report showed adenocarcinoma of the body of pancreas after radical antegrade modular pancreatosplenectomy (RAMPS). In the operation, we found the superior vein and portal vein was surrounded by the pancreatic tissue. The left gastric artery and splenic artery originated respectively from abdominal aorta, and celiac trunk was not viewed. In addition, the common hepatic artery was a branch from the superior mesenteric artery. In general, this is a novel clinical case of pancreatic carcinoma happening in the portal annular pancreas which was accompanied with aberrant hepatic artery and absence of the celiac trunk at the same time. Confronted with the pancreatic neoplasms, the possibility of coexistent annular pancreas and arterial variations should be considered.

Background Patients with malignant tumours of the upper gastrointestinal tract tumours exhibit important alarm symptoms such as dysphagia that warrant clinical investigations. An endoscopic examination of the upper gastrointestinal tract will be required in most cases. This study evaluates the diagnostic potential of index endoscopy in a random population of patients with dysphagia. Methods This is a retrospective analysis of prospectively collected data over 10 years. Patients with previous endoscopic evaluation or upper gastrointestinal pathology were excluded from the study. Data was analysed to see the number and frequency of abnormal findings in upper gastrointestinal tract, and their significance in relation to the presenting symptoms. Results Total number of index endoscopies was 13, 881. 913 patients were included in the study including 465 males (age range: 17–92 years, median: 55 years) and 448 females (age range: 18–100, median: 59 years), with male to female ratio of 1.04: 1. Oesophagus was abnormal in 678 cases (74%) and biopsies were taken in 428 patients (47%). Superficial oesophagitis, Barrett's oesophagus, oesophageal cancer, and oesophageal ulcer were main histological findings. Age more than 50 years and weight loss were significant predictors of oesophageal cancer (p < 0.0001). Male gender, heartburn, epigastric pain, weight loss and vomiting were significantly related to Barrett's oesophagus. A total of 486 gastric and 56 duodenal biopsies were also taken. There were 20 cases of gastric adenocarcinoma. Conclusion OGD is an effective initial investigation to assess patients with dysphagia, especially males above the age of 50 years. Patients may be started on treatment or referred for further investigations, for example, a barium meal in the absence of any anatomical abnormality. PMID:18034883

Henoch-Schönlein purpura (HSP) is the most common vascular disease of childhood. It is a multisystem disease most commonly affecting the skin,joints, gastrointestinal tract, and kidneys, but other organs may be affected, too. Gastrointestinal involvement occurs in approximately 65-90% of patients, ranging from mild symptoms such as abdominal pain, nausea, and vomiting, to more severe manifestations such as gastrointestinal bleeding and intussusception. In most cases, HSP spontaneously resolves without treatment. The use of corticosteroids is controversial and usually reserved for severe systemic manifestations. Some authors suggest that the abdominal pain and gastrointestinal hemorrhage of HSP may respond to steroids, with some suggesting that there is a benefit in their use and describing a regimen. This is a case report of HSP in a fourteen-year-old boy with abdominal pain and hematemesis. Upper endoscopy showed an edematous and erythematous change in the body of the stomach and purpuric lesions in the duodenum, while multiple erosions were found in the antral area. Parenteral corticosteroid therapy with gastric acid secretion inhibitor administration led to regression of gastrointestinal symptoms on the seventh day, with relapses on the fourth and sixth day. Peroral administration of corticosteroids and gradual decrease of daily doses started on the eighth day of abdominal symptoms. New purpuric skin rashes appeared during six weeks. Corticosteroid therapy with gastric acid secretion inhibitors showed a positive effect in our patient with a severe form of HSP accompanied by abdominal pain and gastrointestinal hemorrhage.

The majority of swallowed foreign bodies are thrown spontaneously without causing complications in the digestive system. Multiple number of foreign bodies may be swallowed by psychiatric patients which delay diagnosis and increase the complication rate. Long and hard objects cannot pass through the pylorus, and may cause obstruction, ulceration, bleeding and perforation. Endoscopy is used as an effective method in such cases. An exploratory laparatomy was performed after unsuccessful endoscopic foreign object removal in a 28-year-old schizophrenic patient with gastric outlet obstruction due to multiple cigarette lighter swallowing. Ten lighters were removed from the stomach through gastrotomy and one more lighter was removed from the descending colon by milking through the anus. The aim of this paper is to discuss encountered difficulties in psychiatric patients who underwent surgery due to intake of foreign bodies.

To investigate the value of preoperative barium contrast examination for the diagnosis and operative planning in gastric cancer. Clinical data of 229 gastric cancer patients were analyzed retrospectively. Lesions were divided into three parts: the cardiac, the body, and the antrum. The diagnostic accuracy of localization and the extent of tumor between gastroscopy alone and gastroscopy plus barium contrast were compared with the results of surgical findings. The diagnostic accuracy of localization and the extent of tumor for gastroscopy in the cardiac, the body and the antrum cancers were 100% and 78.4%, 94.6% and 86.5%, 98.1% and 84.6%, respectively, while for gastroscopy plus barium contrast were 100% and 84.8%, 100% and 91.9%, 99.0% and 90.4%, respectively. The diagnostic accuracy of both the localization and the extent of tumor were not significantly different between gastroscopy alone and gastroscopy plus barium contrast (P>0.05). Diagnostic accuracy of the length of esophagus infiltrated by cardiac cancer in gastroscopy was 60.6%, while in gastroscopy plus barium contrast was 90.9%, which was significantly different (P<0.05). Gastroscopy plus barium contrast was more accurate in predicting the possibility of thoracotomy in cardiac cancer infiltrating the lower esophagus. It is necessary to perform preoperative barium contrast examination in cardiac cancer patients, so as to identify whether the lower esophagus is infiltrated and to measure the length of lesion, which can provide evidences for making a decision of thoracotomy. For gastric body and antrum cancer, there is no indication for barium contrast examination if gastroscopy findings are satisfied.

Antihyperglycemic and antinociceptive activity studies were carried out with methanolic extract of whole plants of Bacopa monnieri, respectively, through oral glucose tolerance test and gastric pain model induced by acetic acid in Swiss albino mice. In OGTT (oral glucose tolerance tests) conducted with glucose-challenged mice, the extract, administered at four doses of 50, 100, 200 and 400mg per kg body weight, dose-dependently and significantly inhibited the increase in serum glucose concentrations, respectively, by 33.3, 34.2, 42.1 and 44.2%. A standard antihyperglycemic drug, glibenclamide, when administered at a dose of 10mg per kg body weight, inhibited increase in serum glucose concentration by 50.7%. From the results, it can be concluded that the methanolic extract of the plant possess significant antihyperglycemic potential. In antinociceptive activity tests, administration of the extract at the aforementioned four doses also significantly and dose-dependently reduced the number of acetic acid-induced gastric constrictions in mice. The percent inhibitions in gastric constrictions were, respectively, 43.4, 46.6, 50.0, and 53.4 at the above four doses. A reference antinociceptive drug, aspirin, when administered at a dose of 200 mg per kg body weight, reduced the number of gastric constrictions by 40.0%. Thus the extract at even the lowest dose of 50 mg, demonstrated antinociceptive activity better than that of aspirin, and which activity was much more than aspirin at the other three higher doses tested. The results demonstrate that the plant can be an excellent candidate for further studies towards isolation of antihyperglycemic and pain-killing compounds.

Heterotopic gastric mucosa has been described at various locations of the body; however, the polyp composed of heterotopic gastric mucosa in the small intestine is rare. A 15-year-old boy visited us for investigation of recurrent episodes of melena. Capsule endoscopy (CE) revealed a polypoid tumor in the ileum, with an active nearby hemorrhage. Contrast-enhanced computed tomography (CECT) showed a tumor in the right quadrant of the abdomen, with a diameter of about 18 × 14 mm. The patient was diagnosed with polypoid gastric heterotopia. We performed an operation to resect the lesion. The patient recovered smoothly after surgery and was discharged on postoperative day 7 and followed up for 3 months. He has not experienced gastrointestinal intestinal (GI) symptoms up to now. Giant polypoid gastric heterotopia in the small intestine is extremely rare, which can express as an occasional finding with or without symptoms. Surgical resection is the preferred therapy when symptoms appear.

An 82-year-old male presented with a chief complaint of upper abdominal pain. Subsequently, a bezoar and a gastric ulcer were detected by upper gastrointestinal endoscopy. The bezoar was dark green in color and extremely hard, having a major axis of 7 cm. After hospitalization, 500-1000 ml/day of Coca-Cola was orally administered continuously for 3 weeks. Thereafter, the bezoar decreased in size to a major axis of 4 cm and showed a softening trend. Therefore, lithotripsy was thereafter carried out under endoscopy using forceps.

We studied the effects of enteral nutrition (EN) support initiated 1 week before surgery on postoperative nutritional status, immune function, and inflammatory response in gastric cancer patients. A total of 200 gastric cancer patients were randomly divided into two groups: EN starting 1 week before surgery (study group) and EN starting early after surgery (control group). The two groups received EN support, following different therapeutic schedules, until the 9th day after operation. In the patients, body weight, skinfold thickness, upper-arm circumference, white blood cell count, albumin, prealbumin, C-reactive protein, peripheral immunoglobulins (IgA, IgG, and IgM), T lymphocyte subsets, interleukin-6, and tumor necrosis factor-α were measured 10 days before and after surgery and on the first day after surgery. There was no statistically significant difference in the results of recovery time of passage of gas by anus, abdominal distension, stomachache, blood glucose, hepatic and renal functions, and electrolytes between the two groups of patients (P > 0. 05). Adverse reactions occurred to both groups at 1 and 2 days after operation. Such conditions was improved after the intravenous drip rate was adjusted. The albumin and prealbumin levels of the patients in both groups decreased at 1 day after operation (P < 0. 05). The levels rose when the research was finished (P < 0. 05). The prealbumin level of the study group was higher than that of the control group at 10 days after operation (P < 0. 05). The IgG level of the study group was higher than that of the control group at 10 days after operation (P < 0. 05). The two groups of inflammatory reaction indicators of the study group were lower than those of the control group at 10 days after operation (P < 0. 05). This study indicates that appropriate preoperative EN support for gastric cancer patients can improve their postoperative nutritional status and immune function, can reduce inflammatory response, and is more conducive to the recovery of patients.

Systemic sclerosis (scleroderma) is frequently associated with both gastroesophageal reflux disease (GERD) and simultaneous esophageal dysmotility. Anti-reflux procedures in this patient population must account for the existing physiology of each patient and likely disease progression. We aim to compare perioperative and intermediate outcomes of fundoplication versus gastric bypass for the treatment of GERD. After IRB approval, patients with systemic sclerosis undergoing fundoplication or gastric bypass for the treatment of GERD from 2004 to 2016 were identified. Demographics, perioperative data, immediate complications, and symptom improvement were retrieved and analyzed. Fourteen patients with systemic sclerosis underwent surgical treatment of GERD during the defined study period. Average body mass index was 26 kg/m 2 . Seven fundoplications (2 Nissens, 4 Toupets, and 1 Dor) and 7 Roux-en-Y gastric bypasses (RYGB) were performed. No 30-day mortality was observed in either group. Median follow-up was 97 months for the fundoplication group (range 28-204 months), and 19 months for the RYGB group (range 1-164 months). Preoperatively, dysphagia, heartburn, and regurgitation were present in 71% (n = 10), 86% (n = 12), and 64% (n = 9) of patients, respectively. Eleven patients had pH study prior to surgical intervention, and 91% of them had abnormal acid exposure. Esophagitis was evident in 85% (n = 11) of patients during preoperative upper endoscopy, and two patients had Barrett's esophagus. Impaired esophageal motility was present in all RYGB patients and 71% of fundoplication patients. Of the patients who had assessment of their GERD symptoms at follow-up, all five patients in the RYGB group and only 3 (50%) patients in the fundoplication group reported symptom improvement or resolution. Laparoscopic RYGB as an anti-reflux procedure is safe and may provide an alternative to fundoplication in the treatment of GERD for systemic sclerosis patients with esophageal dysmotility.

Abstract To investigate the learning curve of the application of Huang 3-step maneuver, which was summarized and proposed by our center for the treatment of advanced upper gastric cancer. From April 2012 to March 2013, 130 consecutive patients who underwent a laparoscopic spleen-preserving splenic hilar lymphadenectomy (LSPL) by a single surgeon who performed Huang 3-step maneuver were retrospectively analyzed. The learning curve was analyzed based on the moving average (MA) method and the cumulative sum method (CUSUM). Surgical outcomes, short-term outcomes, and follow-up results before and after learning curve were contrastively analyzed. A stepwise multivariate logistic regression was used for a multivariable analysis to determine the factors that affect the operative time using Huang 3-step maneuver. Based on the CUSUM, the learning curve for Huang 3-step maneuver was divided into phase 1 (cases 1–40) and phase 2 (cases 41–130). The dissection time (DT) (P < 0.001), blood loss (BL) (P < 0.001), and number of vessels injured in phase 2 were significantly less than those in phase 1. There were no significant differences in the clinicopathological characteristics, short-term outcomes, or major postoperative complications between the learning curve phases. Univariate and multivariate analyses revealed that body mass index (BMI), short gastric vessels (SGVs), splenic hilar artery (SpA) type, and learning curve phase were significantly associated with DT. In the entire group, 124 patients were followed for a median time of 23.0 months (range, 3–30 months). There was no significant difference in the survival curve between phases. AUGC patients with a BMI less than 25 kg/m2, a small number of SGVs, and a concentrated type of SpA are ideal candidates for surgeons who are in phase 1 of the learning curve. PMID:27043698

Acute upper gastrointestinal bleeding (UGIB) - initial evaluation and management.

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.

Complex surgical procedures such as esophagectomy and gastrectomy for cancer are associated with substantial morbidity and mortality. The purpose of this study was to evaluate trends in postoperative morbidity, mortality, and associated failure-to-rescue (FTR), in patients who underwent a potentially curative resection for esophageal or gastric cancer in the Netherlands, and to investigate differences between the two groups. All patients with esophageal or gastric cancer who underwent a potentially curative resection, registered in the Dutch Upper GI Cancer Audit (DUCA) between 2011 and 2014, were included. Primary outcomes were (major) postoperative complications, postoperative mortality and FTR. To investigate groups' effect on the outcomes of interest a mixed model was used. Overall, 2644 patients with esophageal cancer and 1584 patients with gastric cancer were included in this study. In patients with gastric cancer, postoperative mortality (7.7% in 2011 vs. 3.8% in 2014) and FTR (38% in 2011 and 19% in 2014) decreased significantly over the years. The adjusted risk of developing a major postoperative complication was lower (OR 0.54; 95% CI 0.42-0.70), but the risk of FTR was higher (OR 1.85; 95% CI 1.05-3.27) in patients with gastric cancer compared to patients with esophageal cancer. Once a postoperative complication occurred, patients with gastric cancer were more likely to die compared to patients with esophageal cancer. Underlying mechanisms like patient selection, and differences in structure and organization of care should be investigated. Next to morbidity and mortality, failure-to-rescue should be considered as an important outcome measure after esophagogastric cancer resections.

2012-09-01

Purpose: Radiation-induced gastric bleeding has been poorly understood. In this study, we described dosimetric predictors for gastric bleeding after fractionated radiation therapy. Methods and Materials: The records of 139 sequential patients treated with 3-dimensional conformal radiation therapy (3D-CRT) for intrahepatic malignancies were reviewed. Median follow-up was 7.4 months. The parameters of a Lyman normal tissue complication probability (NTCP) model for the occurrence of {>=}grade 3 gastric bleed, adjusted for cirrhosis, were fitted to the data. The principle of maximum likelihood was used to estimate parameters for NTCP models. Results: Sixteen of 116 evaluable patients (14%) developed gastric bleeds at amore » median time of 4.0 months (mean, 6.5 months; range, 2.1-28.3 months) following completion of RT. The median and mean maximum doses to the stomach were 61 and 63 Gy (range, 46-86 Gy), respectively, after biocorrection of each part of the 3D dose distributions to equivalent 2-Gy daily fractions. The Lyman NTCP model with parameters adjusted for cirrhosis predicted gastric bleed. Best-fit Lyman NTCP model parameters were n=0.10 and m=0.21 and with TD{sub 50} (normal) = 56 Gy and TD{sub 50} (cirrhosis) = 22 Gy. The low n value is consistent with the importance of maximum dose; a lower TD{sub 50} value for the cirrhosis patients points out their greater sensitivity. Conclusions: This study demonstrates that the Lyman NTCP model has utility for predicting gastric bleeding and that the presence of cirrhosis greatly increases this risk. These findings should facilitate the design of future clinical trials involving high-dose upper abdominal radiation.« less

Helicobacter pylori is a Gram-negative bacterium which has a serious effect on the up to half of the world's population and has been related to different gastric diseases. The goal of this study was to assess the frequency of babA, cagE and cagA genotypes among H. pylori strains isolated from gastric biopsies of endoscopic patients in the north of Iran. The present study was performed on 90 strains of H. pylori isolated from patients with gastric diseases (Gastric ulcer (GU), Duodenal ulcer (DU), Gastritis (G), Non-ulcer dyspepsia (NUD) and Gastric adenocarcinoma (GC)). DNA was extracted from all isolated strains and PCR method was performed to detect the prevalence of babA, cagE and cagA genes using specific primers. Among 90 samples of H. pylori, babA, cagE, and cagA genes were detected in 42.2%, 30% and 82.2% of strains respectively. The statistical analysis showed that the prevalence of cagA gene in GU, G, DU, and NUD was significantly higher than other genes. Moreover, cagA, and babA2 genes was significantly more prevalent in GC patients compared to cagE gene. Our isolates exhibited 8 distinct arrangements of virulence patterns. The occurrence of cagA (35.6%) was the most prevalent pattern followed by cagA/babA2 (20%), and cagA/babA2/cagE (14.4%). In summary, as first report from Guilan province in the north of Iran, we showed significant association between the presence of babA2, cagE, and cagA genes in different types of gastric disorders.

In the current study, we evaluated the impact of exercise intensity on gender differences in upper-body poling among cross-country skiers, as well as the associated differences in aerobic capacity, maximal strength, body composition, technique and extent of training. Eight male and eight female elite skiers, gender-matched for level of performance by FIS points, carried out a 4-min submaximal, and a 3-min and 30-sec maximal all-out test of isolated upper-body double poling on a Concept2 ski ergometer. Maximal upper-body power and strength (1RM) were determined with a pull-down exercise. In addition, body composition was assessed with a DXA scan and training during the previous six months quantified from diaries. Relative to the corresponding female values (defined as 100%), the power output produced by the men was 88%, 95% and 108% higher during the submaximal, 3-min and 30-sec tests, respectively, and peak power in the pull-down strength exercise was 118% higher (all P<0.001). During the ergometer tests the work performed per cycle by the men was 97%, 102% and 91% greater, respectively, and the men elevated their cycle rate to a greater extent at higher intensities (both P<0.01). Furthermore, men had a 61% higher VO2peak, 58% higher 1RM, relatively larger upper-body mass (61% vs 56%) and reported considerably more upper-body strength and endurance training (all P<0.05). In conclusion, gender differences in upper-body power among cross-country skiers augmented as the intensity of exercise increased. The gender differences observed here are greater than those reported previously for both lower- and whole-body sports and coincided with greater peak aerobic capacity and maximal upper-body strength, relatively more muscle mass in the upper-body, and more extensive training of upper-body strength and endurance among the male skiers.

Prerequisite for tracing nervous system evolution is understanding of the body plan, feeding behaviour and locomotion of the first animals in which neurons evolved. Here, a comprehensive scenario is presented for the diversification of cell types in early metazoans, which enhanced feeding efficiency and led to the emergence of larger animals that were able to move. Starting from cup-shaped, gastraea-like animals with outer and inner choanoflagellate-like cells, two major innovations are discussed that set the stage for nervous system evolution. First, the invention of a mucociliary sole entailed a switch from intra- to extracellular digestion and increased the concentration of nutrients flowing into the gastric cavity. In these animals, an initial nerve net may have evolved via division of labour from mechanosensory-contractile cells in the lateral body wall, enabling coordinated movement of the growing body that involved both mucociliary creeping and changes of body shape. Second, the inner surface of the animals folded into metameric series of gastric pouches, which optimized nutrient resorption and allowed larger body sizes. The concomitant acquisition of bilateral symmetry may have allowed more directed locomotion and, with more demanding coordinative tasks, triggered the evolution of specialized nervous subsystems. Animals of this organizational state would have resembled Ediacarian fossils such as Dickinsonia and may have been close to the cnidarian–bilaterian ancestor. In the bilaterian lineage, the mucociliary sole was used mostly for creeping, or frequently lost. One possible remnant is the enigmatic Reissner's fibre in the ventral neural tube of cephalochordates and vertebrates. PMID:26554050

Metastases in the stomach are rare. The increased use of esophagogastroduodenoscopy (EGD), associated with better treatment results for malignancies, requires them to be acknowledged. The aim of this study was to describe a series of cases of metastasis to the stomach, their primary sites, clinical and endoscopic features, treatment, and results. Twenty cases were diagnosed between December 1999 and January 2004. Their analysis included symptomatology, macroscopic presentation, time from diagnosis of the primary tumor to the detection of the gastric metastasis, treatment approach, and survival. The primary sites were the esophagus, skin, lung, cervix, breast, sigmoid colon, and testis. The symptom most frequently requiring EGD was upper gastrointestinal bleeding. Ten patients showed concomitant metastases to other organs. The mean time between diagnosis of the primary tumor and diagnosis of gastric metastasis was 16 months (range, 0 to 56 months). Only seven patients were given some form of treatment after diagnosis of the gastric metastasis. The median survival was 4.75 months. Overall survival during the first year was 20% and survival was nil at 2 years. Gastric metastasis marks advanced disease and the prognosis is poor. New advances in diagnosis and treatment are required for better results.

Raman spectroscopy is a vibrational analytic technique sensitive to the changes in biomolecular composition and conformations occurring in tissue. With our most recent development of near-infrared (NIR) Raman endoscopy integrated with diagnostic algorithms, in vivo real-time Raman diagnostics has been realized under multimodal wide-field imaging (i.e., white- light reflectance (WLR), narrow-band imaging (NBI), autofluorescence imaging (AFI)) modalities. A selection of 177 patients who previously underwent Raman endoscopy (n=2510 spectra) was used to render two robust models based on partial least squares - discriminant analysis (PLS-DA) for esophageal and gastric cancer diagnosis. The Raman endoscopy technique was validated prospectively on 4 new gastric and esophageal patients for in vivo tissue diagnosis. The Raman endoscopic technique could identify esophageal cancer in vivo with a sensitivity of 88.9% (8/9) and specificity of 100.0% (11/11) and gastric cancers with a sensitivity of 77.8% (14/18) and specificity of 100.0% (13/13). This study realizes for the first time the image-guided Raman endoscopy for real-time in vivo diagnosis of malignancies in the esophagus and gastric at the biomolecular level.

To compare proximal gastrectomy (PG) with total gastrectomy (TG) for proximal gastric carcinoma, through the 5-year survival rate, recurrence rate, postoperative complications, and long-term life quality. The meta-analysis was carried out in the General Surgery Department of the Second Affiliated Hospital of Soochow University, Suzhou, Jiangsu Province, China. We searched Medline, EMBASE, and the Cochrane Library from June to November 2012. The literature searches were carried out using medical subject headings and free-text word: `proximal gastrectomy` `total gastrectomy` `partial gastrectomy` `stomach neoplasms` and `gastric cancer`. Two different reviewers carried out the search and evaluated studies independently. Two randomized controlled trials and 9 retrospective studies were included. A total of 1364 patients were included in our study. Our analysis showed that there is no statistically significant difference in 5-year survival rate between PG and TG (60.9% versus 64.4%). But, the recurrence is higher in the PG group than the TG (38.7% versus 24.4%). The anastomotic stenosis rate is also higher in the PG than the TG (27.4% versus 7.4%). Proximal gastrectomy is an option for upper third gastric cancer in terms of safety. However, it is associated with high risk of reflux symptoms and anastomotic stenosis. Therefore, TG should be the first choice for proximal gastric cancer to prevent reflux symptoms.

The improvement of quality of life is of great importance in managing patients with far-advanced gastric cancer. We report a new cure and less invasive method of creating a stomach-partitioning gastrojejunostomy in reduced-port laparoscopic surgery for unresectable gastric cancers with gastric outlet obstruction. A 2.5-cm vertical intraumbilical incision was made, and EZ Access (Hakko Co., Ltd., Tokyo, Japan) was placed. After pneumoperitoneum was created, an additional 5-mm trocar was inserted in the right upper abdomen. A gastrojejunostomy was performed in the form of an antiperistaltic side-to-side anastomosis, in which the jejunal loop was elevated in the antecolic route and anastomosed to the greater curvature of the stomach using an endoscopic linear stapler. The jejunal loop together with the stomach was dissected with additional linear staplers just proximal to the common entry hole so that a functional end-to-end gastrojejunostomy was completed. At the same time, the stomach was partitioned using a linear stapler to leave a 2-cm-wide lumen in the lesser curvature. Subsequently, jejunojejunostomy was performed 30 cm distal to the gastrojejunostomy, and the stomach-partitioning gastrojejunostomy resembling Roux-en Y anastomosis was completed. All patients resumed oral intake on the day of operation. Neither anastomotic leakage nor anastomotic stricture was observed. Our less invasive palliative operation offers the utmost priority to improve quality of life for patients with unresectable gastric cancer.

Obesity in women of reproductive age is a serious concern regarding reproductive health. In many cases of infertility in obese women, reduction of body weight may lead to spontaneous pregnancy, without the need for more specific methods of treatment. Bariatric surgery is safe and is the most effective method for body weight reduction in obese and very obese patients. In practice there are two bariatric techniques; gastric banding, which leads to weight loss through intake restriction, and gastric bypass, leads to weight loss through food malabsorption. Gastric bypass surgery (the more frequently performed procedure), in most cases, leads to changes in eating habits and may result in vomiting, diarrhea and rapid body mass reduction. There are reliable data describing the continuous increase in the number of women who are trying to conceive, or are already pregnant, following bariatric surgery. Most medical specialists advise women to avoid pregnancy within 12-18 months after bariatric surgery. This allows for time to recover sufficiency from the decreased absorption of nutrients caused by the bariatric surgery. During this period there is a need for the use of reliable contraception. As there is a risk for malabsorption of hormones taken orally, the combined and progestogen-only pills are contraindicated, and displaced by non-oral hormonal contraception or non-hormonal methods, including intrauterine devices and condoms.

The physiology underlying Roux-en-Y gastric bypass: a status report

Obesity and its related comorbidities can be detrimental for the affected individual and challenge public health systems worldwide. Currently, the only available treatment options leading to clinically significant and maintained body weight loss and reduction in obesity-related morbidity and mortality are based on surgical interventions. This review will focus on two main clinical effects of Roux-en-Y gastric bypass (RYGB), namely body weight loss and change in eating behavior. Animal experiments designed to understand the underlying physiological mechanisms of these post-gastric bypass effects will be discussed. Where appropriate, reference will also be made to vertical sleeve gastrectomy. While caloric malabsorption and mechanical restriction seem not to be major factors in this respect, alterations in gut hormone levels are invariably found after RYGB. However, their causal role in RYGB effects on eating and body weight has recently been challenged. Other potential factors contributing to the RYGB effects include increased bile acid concentrations and an altered composition of gut microbiota. RYGB is further associated with remarkable changes in preference for different dietary components, such as a decrease in the preference for high fat or sugar. It needs to be noted, however, that in many cases, the question about the necessity of these alterations for the success of bariatric surgery procedures remains unanswered. PMID:25253084

Abstract Background Aside from Helicobacter pylori, another cause for the development or worsening of gastrointestinal ulcers is scrub typhus, an acute febrile disease caused by Orientia tsutsugamushi. We aimed to compare the endoscopic characteristics of peptic ulcers caused by these infectious agents. Methods This retrospective case–control study involved patients who underwent upper gastrointestinal endoscopy at Chosun University Hospital in Korea. Results In total, 141 patients with peptic ulcer were included in the study. Compared with patients with O. tsutsugamushi infection (n = 62; age, 63.8 ± 12.1 years; male sex, 42%), those with H. pylori infection (n = 79; age, 53.0 ± 14.8 years; male sex, 81%) were younger and more likely to be male (P < 0.001 for both). Patients with O. tsutsugamushi infection were more likely to have multiple lesions (40/62, 64.5% vs. 37/79, 46.8%; P = 0.042) and irregular-shaped lesions (27/62, 43.6% vs. 20/79, 25.3%; 
P = 0.031). Patients with H. pylori infection had higher incidence of hemorrhagic ulcers (26/79, 32.9% vs. 8/62, 12.9%; P = 0.007), and lesions occurred most often in the duodenum (43.0%), followed by the antrum (36.7%), body (34.2%), and angle (12.7%) of the stomach. In patients with O. tsutsugamushi infection, lesions occurred most often in the antrum (70.97%) of the stomach. In both groups, gastric ulcer lesions occurred most often in the antrum, followed by the body and angle of the stomach (36.7% vs. 70.97%, 34.2% vs. 22.6%, and 12.7% vs. 14.5% for gastric ulcers associated with H. pylori and O. tsutsugamushi infection, respectively). Patients with O. tsutsugamushiinfection had significantly higher incidence of ulcers on the antrum (70.97% vs. 36.7%, P < 0.001) and the greater curvature (45.2% vs. 24.0%, P = 0.012). Finally, 35.5% of patients with gastric ulcer caused by scrub typhus also had duodenal ulcer. Conclusion This is the first study to compare endoscopic features of peptic ulcers caused by H. pylori and O. tsutsugamushi. Peptic ulcers in patients with H. pylori infection occurred predominantly in the antrum/body/lesser curvature and presented with single, round/oval lesions, while ulcers in patients with scrub typhus occurred predominantly in the antrum/greater curvature and presented with multiple, irregular lesions. Scrub typhus should be considered as a cause of duodenal ulcer in scrub typhus-endemic areas. Disclosures All authors: No reported disclosures.

Purpose: To evaluate the effects of left gastric artery embolization (LGAE) on plasma ghrelin levels, abdominal fat, and body weight in beagles. Methods: The institutional animal care and use committee approved this study. Fifteen healthy adult beagles (12 male and three female animals) were randomly divided into three experimental groups: LGAE was proceeded with mixed emulsion of bleomycin A{sub 5} hydrochloride and lipiodol (group A), and polyvinyl alcohol particles (group B). Transcatheter saline injections in the left gastric artery were performed as a control. Weight and fasting plasma ghrelin levels were obtained at baseline and at weekly intervals for 8more » weeks after the procedure in all animals. All animals were scanned and measured by multidetector computed tomography at baseline and at week 8 for evaluation of abdominal fat. Results: In LGAE-treated animals, plasma ghrelin and body weight significantly decreased compared to control animals (group A: P = 0.007 and P = 0.000; group B: P = 0.004 and P = 0.000, respectively). Subcutaneous fat size was also significantly reduced (P = 0.011 and P = 0.027 for groups A and B, respectively). The decreasing percentage in ghrelin levels at week 6 (peak of recovery) of LGAE-treated animals were negatively correlated with the size of area supplied by left gastric artery (r = -0.693, P = 0.026). Conclusion: LGAE could suppress the plasma concentration of ghrelin, which results in subcutaneous fat size reduction and weight loss. Compensatory ghrelin production might occur in the remnant gastric fundus after LGAE.« less

Background : Endoscopic submucosal dissection carries an increased risk of bleeding and perforation. The creation of a long lasting submucosal cushion is essential for the safe and complete removal of the lesion. There is not a suitable experimental model for evaluation of the durability of the cushioning effect of different solutions. Aim : To describe an improved experimental model to evaluate submucosal injection solutions. Methods : A total of four domestic pigs were employed to evaluate two different submucosal fluid solutions in the gastric submucosa. After midline laparotomy, the anterior gastric wall was incised from the gastric body to the antrum and its mucosal surface was exposed by flipping inside out the incised gastric wall. Two different solutions (10% mannitol and normal saline) were injected in the submucosa of the anterior wall of the distal gastric body. All submucosal cushions were injected until they reach the same size, standardized as 1.0 cm in height and 2.0 cm in diameter. A caliper and a ruler were employed to guarantee accuracy of the measurements. Results : All four animal experiments were completed. All submucosal cushions had the exact same size measured with caliper and a ruler. By using the mannitol solution, the mean duration of the submucosal cushion was longer than the saline solution: 20 and 22 min (mean, 21 min) vs 5 and 6 min (mean, 5.5 min) Conclusions : This experimental model is simple and evaluate the duration, size, and effect of the submucosal cushion, making it more reliable than other models that employ resected porcine stomachs or endoscopic images in live porcine models.

During the past 10 years efforts have been made to develop a radioisotope test for gastric malignancy. Phosphorus-32 was used by intracavity procedures (gastric tube-detector; autoradiography) but the procedures were difficult. In 1961 the first scintillographic assays with scanners and then with scintillation cameras were performed. Iodine-131 was used at first and since 1965 /sup 99m/Tc, which is superior from a physical point of view. It was established that a cold space-occupying lesion in the gastroscan indicates malignancy and that a foggy scan, general or local, may also indicate a neoplastic lesion. All other conditions, including peptic ulcer and gastritis,more » give a normal scan. In the dog, injection of /sup 99m/Tc indicated a turnover of the isotope in the body, and that it is concentrated in the gastric mucosa and excreted in the gastric juice. A gastroscintillographic study in 220 patients showed that 54 of them had stomach malignancies (51 carcinoma and 3 sarcoma). Only neoplasms at least 2 cm in diameter were visualized. In all the patients, clinical, radiological, and biochemical examinations were performed and in most, pathological examinations as well. There was correspondence with the final diagnosis in 80% of the scintillographed cancers and in 92% of those studied roentgenologically. The false scinttllographic diagnosed conclusions were mostly in diffurent patients than in those with false roentgenological diagnoses. It can therefore be concluded that the two methods are complementary. The radiological exposure due to /sup 99m/Tc scintivisualization is low, 200 mrad to the stomach and l5 mrad to the whole body.

Little information from prospective clinical trials is available on the influences of surgical approaches on postoperative body compositions and nutritional status. We designed a prospective non-randomized trial to compare postoperative chronological changes in body composition and nutritional status between laparoscopic and open distal gastrectomy for stage I gastric cancer (GC). Body compositions and nutritional indicators in blood tests were measured at the baseline and at the 1st, 3rd, 6th, and 12th postoperative months (POM). The primary end point was the decrease relative to the baseline in the body muscle mass at POM 6. Ninety-six patients for the laparoscopic group and 52 for the open group were eligible for data analysis. No significant differences were found in any baseline demographics, body compositions, and nutritional indicators between the groups. The changes of body muscle mass at POM 6 were similar in both groups. Overall, no significant differences between the groups were observed in any of the body composition and nutritional indicators during the first year after surgery. Postoperative body compositions and nutritional status were not affected by surgical approaches during the first 12 months after surgery in patients who underwent distal gastrectomy for stage I GC. © 2017 S.

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 it is a safe and effective procedure with lower invasiveness.

The gastroprotective effect of esculin was investigated in a mouse model of ethanol-induced gastric lesion. Administration of esculin at doses of 5, 10, and 20 mg/kg body weight prior to ethanol ingestion led to significant gastroprotection compared with untreated mice. Gastric mucosal lesions were evaluated by macroscopic and histopathological alterations, lesion index, and myeloperoxidase (MPO) activity. Pretreatment with esculin significantly reduced macroscopic and histopathological damage, gastric lesion index, and MPO activity in a dose-dependent manner. Moreover, esculin significantly reduced nitric oxide (NO) production, inducible NO synthase (iNOS) levels, and nuclear factor-kappa B (NF-κB) p65 protein expression in gastric tissues after ethanol challenge. Analysis of inflammatory cytokines indicated that esculin pretreatment markedly suppressed the increased expression of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in ethanol-treated mice. The results demonstrate a protective effect of esculin against gastric injury and suggest that the underlying mechanism might be associated with inhibition of NF-κB activation, which subsequently reduces expression of iNOS, TNF-α, and IL-6. © 2016 Société Française de Pharmacologie et de Thérapeutique.

Hericium erinaceus is a culinary-medicinal mushroom that is used in traditional medicine, in folk medicine, and as medicinal cuisine in Asian countries such as China, Japan, and Korea. H. erinaceus exhibits various pharmacological properties, such as anti-cancer, immunomodulation, anti-dementia, and anti-gastric ulcer effects. The extracts of the fruiting body of H. erinaceus demonstrate anti-gastritis activity. However, the active principle in the extract, as well as the mechanism to treat gastric ulcers, remains uncertain. The current study aims to identify the active component, with anti-gastric ulcer function, from the extracts of the H. erinaceus mycelium culture. In the experiment, anti-gastric ulcer activity was evaluated using an ethanol-induced ulcer model in mice and with an 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay using MC cell lines. The results suggest that the polysaccharide fraction can significantly decrease the ulcerated area compared with the control group and the effect is fairly dose dependent, irrespective of animal or cell experiments. These results indicate that the polysaccharide fraction is the active component of the H. erinaceus mycelium culture, which protects against gastric ulcers.

This study investigated the variation in incidence of all, and six subgroups of, oesophageal and gastric cancer between ethnic groups. Data on all oesophageal and gastric cancer patients diagnosed between 2001 and 2007 in England were analysed. Self-assigned ethnicity from the Hospital Episode Statistics dataset was used. Male and female age-standardised incidence rate ratios (IRRs) were calculated for each ethnic group, using White groups as the references. Ethnicity information was available for 83% of patients (76 130/92 205). White men had a higher incidence of oesophageal cancer, with IRR for the other ethnic groups ranging from 0.17 95% confidence interval (CI) (0.15-0.20) (Pakistani men) to 0.58 95% CI (0.50-0.67) (Black Caribbean men). Compared with White women, Bangladeshi women (IRR 2.02 (1.24-3.29)) had a higher incidence of oesophageal cancer. For gastric cancer, Black Caribbean men (1.39 (1.22-1.60)) and women (1.57 (1.28-1.92)) had a higher incidence compared with their White counterparts. In the subgroup analysis, White men had a higher incidence of lower oesophageal and gastric cardia cancer compared with the other ethnic groups studied. Bangladeshi women (3.10 (1.60-6.00)) had a higher incidence of upper and middle oesophageal cancer compared with White women. Substantial ethnic differences in the incidence of oesophageal and gastric cancer were found. Further research into differences in exposures to risk factors between ethnic groups could elucidate why the observed variation in incidence exists.

To provide endoscopic screening nationwide, we estimated the proportion of increase in the number of endoscopic examinations with the introduction of endoscopic screening, based on a national survey. The total number of endoscopic examinations has increased, particularly in clinics. Based on the national survey, the total number of participants in gastric cancer screening was 3 784 967. If 30% of the participants are switched from radiographic screening to endoscopic screening, approximately 1 million additional endoscopic examinations are needed. In Japan, the participation rates in gastric cancer screening and the number of hospitals and clinics offering upper gastrointestinal endoscopy vary among the 47 prefectures. If the participation rates are high and the numbers of hospitals and clinics are small, the proportion of increase becomes larger. Based on the same assumption, 50% of big cities can provide endoscopic screening with a 5% increase in the total number of endoscopic examinations. However, 16.7% of the medical districts are available for endoscopic screening within a 5% increase in the total number of endoscopic examinations. Despite the Japanese government's decision to introduce endoscopic screening for gastric cancer nationwide, its immediate introduction remains difficult because of insufficient medical resources in rural areas. This implies that endoscopic screening will be initially introduced to big cities. To promote endoscopic screening for gastric cancer nationwide, the disparity of medical resources must first be resolved. © 2016 The Authors.

Maker, Ajay V

The majority of gastrointestinal stromal tumors (GISTs) are located in the stomach. With greater experience in minimally invasive oncologic surgery, gastric GISTs are being increasingly approached laparoscopically. Posterior proximally located endophytic gastric GISTs can be challenging to approach laparoscopically and excise with an adequate margin without an anterior or posterior gastrotomy, or intragastric ports. The gastrocolic and gastrosplenic ligaments are divided up to the gastroesophageal junction. The left lateral segment of the liver is mobilized to allow anterior reflection of the gastric fundus. Intraoperative ultrasound confirms the location and extent of the tumor base. Upper endoscopy is performed to trans-illuminate, confirm tumor location, and search for multifocality. Traction sutures are placed around the tumor to distract endophytic lesions. With organo-axial rotation of the stomach using the stay sutures, an endoGIA stapler approximates the posterior fundic wall under the base of the lesion ensuring an adequate margin and eliminating the risk of gastric spillage. Appropriate stapler placement and margins are assisted real-time endoscopically with picture-in-picture. The stapleline is tested for leaks and inspected for hemostasis laparoendoscopically. Complete resection of GISTs with adequate margins is performed with sound oncologic principles and demonstrated in tumors of varying sizes and locations in the proximal posterior stomach, including near the GE junction. This video demonstrates a simple laparoendoscopic technique to quickly localize even small tumors, visually confirm adequate margins, and excise gastric GISTs without spillage or gastrotomy that are located in a typically difficult area of the stomach to approach laparoscopically.

Marked epidemiological changes in upper gastrointestinal diseases and Helicobacter pylori infection have taken place in the Asian Pacific region. In particular, differences with respect to race in the multiracial Asian population in Malaysia have been important and interesting. A time trend study of upper gastrointestinal disease and H. pylori infection in three time periods: 1989-1990, 1999-2000 and 2009-2010 spanning a period of 20 years was carried out. Consecutive first time gastroscopies carried out on patients attending the University of Malaya Medical Center were studied. Diagnoses and H. pylori infection status were carefully recorded. A steady decline in prevalence of duodenal ulcer (DU) and gastric ulcer (GU) from 21.1% to 9.5% to 5.0% and from 11.9% to 9.4% to 9.9% while an increase in erosive oesophagitis (EO) from 2.0% to 8.4% to 9.5% (chi-square for trend; P < 0.001) for the periods 1989-1990, 1999-200 and 2009-2010 were observed. The overall prevalence of H. pylori had also decreased from 51.7% to 30.3% to 11.1% for the same periods of time. The proportion of H. pylori positive ulcers had also decreased: DU (90.1%-69.8%-28.9%) and GU (86.6-56.8%-18.9%) (P < 0.001). This was observed in Malays, Chinese and Indians but the difference over time was most marked in Malays. There was a steady decline in the proportion of patients with gastric and oesophageal cancers. Peptic ulcers have declined significantly over a 20-year period together with a decline in H. pylori infection. In contrast, a steady increase in erosive oesophagitis was observed. Gastric and oesophageal squamous cell cancers have declined to low levels. © 2016 John Wiley & Sons Ltd.

To validate laser doppler flowmetry (LDF) for measurement of blood flow in the stomach wall of dogs with gastric dilatation-volvulus (GDV). Six purpose-bred dogs and 24 dogs with naturally occurring GDV. Experimental and clinical. Capillary blood flow in the body of the stomach and pyloric antrum was measured with LDF (tissue perfusion unit (TPU) before and after induction of portal hypertension (PH) and after PH plus gastric ischemia (GI; PH + GI) and compared with flow measured by colored microsphere technique. Capillary flow was measured by LDF in the stomach wall of dogs with GDV. PH and PH+GI induced a significant reduction in blood flow in the body of the stomach (P = .019). A significant positive correlation was present between percent changes in capillary blood flow measured by LDF and colored microspheres after induction of PH + GI in the body of the stomach (r = 0.94, P = .014) and in the pyloric antrum (r = 0.95, P = .049). Capillary blood flow measured in the body of the stomach of 6 dogs that required partial gastrectomy (5.00+/-3.30 TPU) was significantly lower than in dogs that did not (28.00+/-14.40 TPU, P = .013). LDF can detect variations in blood flow in the stomach wall of dogs. LDF may have application for evaluation of stomach wall viability during surgery in dogs with GDV.

Recent studies suggest that in addition to movements between ankle and hip joints, movements of the upper body, in particular of the arms, also significantly contribute to postural control. In line with these suggestions, we analyzed regulatory movements of upper and lower body joints supporting dynamic balance regulation during challenged locomotion. The participants walked over three beams of varying width and under three different verbally conveyed restrictions of arm posture, to control the potential influence of arm movements on the performance: The participants walked (1) with their arms stretched out perpendicularly in the frontal plane, (2) spontaneously, i.e., without restrictions to the arm movements, and (3) with their hands on their thighs. After applying an inverse-dynamics analysis to the measured joint kinematics, we investigated the contribution of upper and lower body joints to balance regulation in terms of torque amplitude and variation. On the condition with the hands on the thighs, the contribution of the upper body remains significantly lower than the contribution of the lower body irrespective of beam widths. For spontaneous arm movements and for outstretched arms we find that the upper body (including the arms) contributes to the balancing to a similar extent as the lower body. Moreover, when the task becomes more difficult, i.e., for narrower beam widths, the contribution of the upper body increases, while the contribution of the lower body remains nearly constant. These findings lend further support to the hypothetical existence of an “upper body strategy” complementing the ankle and hip strategies especially during challenging dynamic balance tasks.

Gastric volvulus is an abnormal rotation of all or a part of the stomach around one of its axes. It is a rare cause of intestinal obstruction in children. This anomaly can be primary, due to abnormalities of the gastric ligaments, or secondary to other congenital malformations. We report on the cases of five children treated between January 1994 and December 2011, four boys and one girl, with a medium age of 7 months. Diagnosis was based on clinical features, particularly in the upper gastrointestinal Rx contrast study, which confirmed the diagnosis. Four out of the five children underwent laparoscopic surgery with fixation of the stomach. A diaphragmatic hernia was associated in one case. Antireflux surgery was performed in three cases, and a diaphragmatic defect was closed in one case. The follow-up was uneventful after a medium period of 7 years. good knowledge of this anomaly is the guarantee of early diagnosis and optimum treatment to ameliorate the prognosis.

Intrauterine devices (IUD) are the most common contraceptive methods all over the world. Besides many advantages, there are also some complications of this method. The most important complication of IUD is uterine perforation. The reported incidence of IUD perforation ranges from 0.2 to 9.6 per thousand insertions. In this article we would like to report a case that has an IUD migrated to the gastric serosa. A 41 years-old Turkish woman presented with abdominal pain. Plain X-ray of the abdomen demonstrated two IUDs, one in the upper quadrant of the abdomen, the other in the pelvic area and determined in the endometrium by TV-USG (transvaginal ultrasonography). Laparascopy was performed and the IUD, lying over the omentum of stomach was removed. This report demonstrates the first case in the literature that has an IUD embedded in the gastric serosa and also a second IUD in uterine cavity. The management was performed laparoscopically. No complication was observed during and after operation.

We have studied 80 patients with pernicious anaemia. Upper gastrointestinal endoscopy (with biopsy and cytology) showed no lesion other than atrophic gastritis in 34 patients. Thirty three patients, however, had varying degrees of gastric mucosal dysplasia, which was detected more frequently by histology than by cytology. The endoscopic appearance of the mucosa was abnormal in four of the six patients with moderate dysplasia, and in all three patients with severe dysplasia. One patient was found to have a small carcinoma in the gastric antrum, and underwent total gastrectomy; 18 patients had polyps (often multiple); four of these were treated by endoscopic polypectomy. One of the patients with polyps had multiple carcinoid tumours, and an asymptomatic parathyroid adenoma. Seventeen of the patients also underwent barium meal examination; abnormalities were revealed in only three of the seven patients with lesions visible at endoscopy. Our results justify further endoscopic studies in patients with pernicious anaemia, and sequential examinations to establish the natural history of gastric dysplasia.

Type I gastric carcinoid tumors result from hypergastrinemia in 1%-7% of patients with pernicious anemia. We diagnosed pernicious anemia in a 48-year-old female patient with complaint of fatigue for three months. She had no gastrointestinal symptoms. Endoscopic examination ot the upper gastrointestinal tract revealed atrophic gastritis and a polypoid lesion in the corpus of 3-4 mm in size. Endoscopic polypectomy was performed. Histopathological examination of the specimen revealed positive chromogranin A and synaptophysin stainings compatible with the diagnosis of a carcinoid tumor. Serum gastrin level was increased, urinary 5-hydroxyindoleacetic acid was within the normal range. There was no other symptom, sign, or laboratory finding of a carcinoid syndrome in the patient. No metastasis was found with indium-111 octreotide scan, computed tomographies of abdomen and thorax. Type I gastric carcinoid tumors are only rarely solitary and patients with tumors < 1 cm in size may benefit from endoscopic polypectomy. PMID:16830392

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.

A 55-year-woman presented with abdominal fullness. An abdominal MRI disclosed ovarian and uterine tumors. Under the pathological diagnosis of Kruckenberg tumor, total hysterectomy and bilateral adenexectomy were performed. Gastrointestinal endoscopy disclosed type 3 on the greater curvature and anterior wall of the middle gastric body. The gastric cancer had a similar histology, which suggested the tumor origin and led to the diagnosis of c-stage IV. She received 6 courses of SOX chemotherapy. Staging laparoscopy revealed no peritoneal metastasis and negative cytodiagnosis of ascites. She underwent total gastrectomy with D2 lymphadenectomy. In May 2017, after S-1 chemotherapy, no metastasis to other organs was observed.

In clinical trials, acotiamide hydrochloride (acotiamide: Z-338) has been reported to be useful in the treatment of functional dyspepsia. Here, we investigated the effects of acotiamide on gastric contraction and emptying activities in rats in comparison with itopride hydrochloride (itopride) and mosapride citrate (mosapride). We also examined in vitro the compound's inhibitory effect on acetylcholinesterase (AChE) activity derived from rat stomach. In in vivo studies, acotiamide (30 and 100mg/kg s.c.) and itopride (100mg/kg s.c.) markedly enhanced normal gastric antral motility in rats. In gastric motility dysfunction models, acotiamide (100mg/kg s.c.) and itopride (100mg/kg s.c.) improved both gastric antral hypomotility and the delayed gastric emptying induced by clonidine, an α(2)-adrenoceptor agonist. In contrast, mosapride (10mg/kg s.c.) had no effect on these models. Like the AChE inhibitors itopride (30 mg/kg s.c.) and neostigmine (10 μg/kg s.c.), acotiamide (10mg/kg s.c.) also clearly enhanced gastric body contractions induced by electrical stimulation of the vagus, which were abolished by atropine and hexamethonium, whereas mosapride (3 and 10mg/kg s.c.) did not. In in vitro studies, acotiamide concentration-dependently inhibited rat stomach-derived AChE activity (IC(50)=2.3 μmol/l). In addition, stomach tissue concentrations of acotiamide after administration at 10mg/kg s.c. were sufficient to produce inhibition of AChE activity in rat stomach. These results suggest that acotiamide stimulates gastric motility and improves gastric motility dysfunction in rats by inhibiting AChE activity, and may suggest a role for acotiamide in improving gastric motility dysfunction in patients with functional dyspepsia.

Effect of surfactants, gastric emptying, and dosage form on supersaturation of dipyridamole in an in vitro model simulating the stomach and duodenum.

PubMed

Mitra, A; Fadda, H M

2014-08-04

The purpose of this study was to investigate the influence of gastric emptying patterns, surfactants, and dosage form on the supersaturation of a poorly soluble weakly basic drug, dipyridamole, using an in vitro model mimicking the dynamic environment of the upper gastrointestinal tract, and, furthermore, to evaluate the usefulness of this model in establishing correlations to in vivo bioavailability for drugs with solubility/dissolution limited absorption. A simulated stomach duodenum model comprising four compartments was used to assess supersaturation and precipitation kinetics as a function of time. It integrates physiologically relevant fluid volumes, fluid transfer rates, and pH changes of the upper GI tract. Monoexponential gastric emptying patterns simulating the fasted state were compared to linear gastric emptying patterns simulating the fed state. The effect of different surfactants commonly used in oral preparations, specifically, sodium lauryl sulfate (SLS), poloxamer-188, and polysorbate-80, on dipyridamole supersaturation was investigated while maintaining surface tension of the simulated gastric fluids at physiological levels and without obtaining artificial micellar solubilization of the drug. The supersaturation behavior of different dose strengths of dipyridamole was explored. Significant levels of dipyridamole supersaturation were observed in the duodenal compartment under all the different in vivo relevant conditions explored. Dipyridamole supersaturation ratios of up to 11-fold have been observed, and supersaturation has been maintained for up to 120 min. Lower duodenal concentrations of dipyridamole were observed under linear gastric emptying patterns compared to mononexponential gastric emptying. The mean duodenal area under concentration-time curves (AUC60min) for the dipyridamole concentration profile in the duodenal compartment is significantly different for all the surfactants explored (P < 0.05). Our investigations with the different surfactants and comparison of dosage form (solution versus suspension) on the precipitation of dipyridamole revealed that crystal growth, rather than nucleation, is the rate-limiting step for the precipitation of dipyridamole. A linear dose-response relationship was found for the mean in vitro duodenal area under concentration-time curves (AUC∞) in the dose range of 25 mg to 100 mg (R(2) = 0.886). This is in agreement with the pharmacokinetic data of dipyridamole reported in the literature. The simulated stomach duodenum model can provide a reliable and discriminative screening tool for exploring the effect of different physiological variables or formulations on the supersaturation/precipitation kinetics of weakly basic drugs with solubility limited absorption. The amount of drug in solution in the duodenal compartment of the SSD correlates to bioavailability for the weakly basic drug, dipyridamole, which has solubility limited absorption and undergoes supersaturation/precipitation.

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.

Bariatric surgery is effective in reducing all-cause and cause-specific long-term mortality. Whether the long-term mortality benefit of surgery applies to all ages at which surgery is performed is not known. To examine whether gastric bypass surgery is equally effective in reducing mortality in groups undergoing surgery at different ages. All-cause and cause-specific mortality rates and hazard ratios (HRs) were estimated from a retrospective cohort within 4 categories defined by age at surgery: younger than 35 years, 35 through 44 years, 45 through 54 years, and 55 through 74 years. Mean follow-up was 7.2 years. Patients undergoing gastric bypass surgery seen at a private surgical practice from January 1, 1984, through December 31, 2002, were studied. Data analysis was performed from June 12, 2013, to September 6, 2015. A cohort of 7925 patients undergoing gastric bypass surgery and 7925 group-matched, severely obese individuals who did not undergo surgery were identified through driver license records. Matching criteria included year of surgery to year of driver license application, sex, 5-year age groups, and 3 body mass index categories. Roux-en-Y gastric bypass surgery. All-cause and cause-specific mortality compared between those undergoing and not undergoing gastric bypass surgery using HRs. Among the 7925 patients who underwent gastric bypass surgery, the mean (SD) age at surgery was 39.5 (10.5) years, and the mean (SD) presurgical body mass index was 45.3 (7.4). Compared with 7925 matched individuals not undergoing surgery, adjusted all-cause mortality after gastric bypass surgery was significantly lower for patients 35 through 44 years old (HR, 0.54; 95% CI, 0.38-0.77), 45 through 54 years old (HR, 0.43; 95% CI, 0.30-0.62), and 55 through 74 years old (HR, 0.50; 95% CI, 0.31-0.79; P < .003 for all) but was not lower for those younger than 35 years (HR, 1.22; 95% CI, 0.82-1.81; P = .34). The lack of mortality benefit in those undergoing gastric bypass surgery at ages younger than 35 years primarily derived from a significantly higher number of externally caused deaths (HR, 2.53; 95% CI, 1.27-5.07; P = .009), particularly among women (HR, 3.08; 95% CI, 1.4-6.7; P = .005). Patients undergoing gastric bypass surgery had a significantly lower age-related increase in mortality than severely obese individuals not undergoing surgery (P = .001). Gastric bypass surgery was associated with improved long-term survival for all patients undergoing surgery at ages older than 35 years, with externally caused deaths only elevated in younger women. Gastric bypass surgery is protective against mortality even for older patients and also reduces the age-related increase in mortality observed in severely obese individuals not undergoing surgery.

We present a case of emergent thoracoscopic management of volvulus of the gastric conduit following minimally invasive Ivor-Lewis esophagectomy. The patient is a 69-year-old Caucasian male with a history of adenocarcinoma of the lower third of the esophagus. Initial presentation was dysphagia with solid foods, which progressed in severity until he was unable to swallow anything. EUS demonstrated a partially obstructing mass at 33 cm; biopsy revealed poorly differentiated adenocarcinoma, stage T3N2Mx. PET scan did not reveal any metastatic disease. Preoperative management included neo-adjuvant chemoradiation therapy (5-FU and cisplatin) and early placement of a jejunal feeding tube. Intra-operative leak test was performed as a matter of routine following completion of the esophagogastric anastomosis. A nasogastric tube was placed intra-operatively and removed on POD2 according to our standard pathway. Postoperatively, the patient progressed without difficulty to POD4, when we routinely obtain an upper GI swallow study. This demonstrated a lack of transit of contrast through the distal neo-esophagus. Follow-up endoscopy revealed volvulus of the gastric conduit with obliteration of the lumen. We immediately took the patient to the OR for thoracoscopic detorsion, which we accomplished successfully by entering the existing trochar sites and using blunt dissection.␣Upon entering the thoracic cavity, the staple line that had been oriented anteriorly was now posterior. Attachments were gently teased away from the chest wall and the conduit was detorsed and anchored to the chest wall in the correct orientation with silk suture. Intra-operative endoscopy demonstrated a patent conduit. Postoperative upper GI fluoroscopy now showed good transit of contrast. The patient continued to improve and was eventually advanced to mechanical soft diet and discharged on postoperative day 9. Early intervention is indicated in cases of volvulus of the gastric conduit following Ivor-Lewis esophagectomy.

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.

Burkitt's lymphoma (BL) is an uncommon cause of non-Hodgkin lymphoma in adults and accounts for only 0.1-0.5% of all malignant tumors of the colon and rectum. Very few cases of rectosigmoid and stomach BL have been reported in adults. A 51-year-old Hispanic woman presented with a 1-month history of hematochezia, associated with a foreign-body sensation in the rectum and 7 kg weight loss. Initial laboratory workup showed normocytic anemia and positive fecal occult blood. Computed tomography of the abdomen revealed an asymmetric appearance of the stomach and pylorus with nodularity of the mucosa and thickening of the posterior wall, and a 10.8-cm rectal mass. Esophagogastroduodenoscopy and colonoscopy were performed and biopsies of the stomach and rectum were obtained; histopathology demonstrated involvement by Burkitt's lymphoma in the gastric body nodule and rectal mass. After 4 cycles of chemotherapy, a follow-up abdominal CT demonstrated complete resolution of the mural thickening of the rectum and no intra-abdominal lymphadenopathy. Our case illustrates the importance of considering BL in the extensive differential diagnosis of rectal bleeding, change in bowel habits, and other lower and upper GI symptoms, since the rapidly growing nature of this rare malignancy requires a prompt diagnosis and initiation of appropriate therapy.

Despite the fact that ∼85% of bariatric operations are performed in women, the effects of the reproductive axis function on outcome of bariatric surgery remain to be determined. Here we developed the first published model of Roux-en-Y gastric bypass (RYGB) in female rats. We show in ovariectomized rats receiving estradiol or control treatment that (1) RYGB-induced body weight loss and (2) the satiating efficacy of endogenous glucagon-like peptide-1 and cholecystokinin satiation were significantly increased in estradiol-treated rats. These data are relevant to the care of obese women, in particular perimenopausal women, undergoing bariatric surgery. Copyright © 2012 AGA Institute. Published by Elsevier Inc. All rights reserved.

Background Patients with symptoms suggestive of gastroparesis exhibit several symptoms, such as epigastric pain, postprandial fullness, bloating and regurgitation. It is uncertain if such symptoms reflect underlying oesophageal motor disorder. Aims To examine whether patients with epigastric pain and postprandial distress syndrome suggestive of functional dyspepsia and/or gastroparesis also have concomitant oesophageal motility abnormalities and, if so, whether there are any associations between these disturbances. Methods In this retrospective cohort study, consecutive patients with functional gastrointestinal symptoms suggestive of gastric neuromuscular dysfunction (gastroparesis or functional dyspepsia) underwent clinical assessment, gastric scintigraphy, oesophageal high-resolution manometry and ambulatory pH monitoring using standard protocols. Results We studied 61 patients with various functional upper gastrointestinal symptoms who underwent gastric scintigraphy, oesophageal high-resolution manometry and ambulatory pH monitoring. Forty-four patients exhibited gastroparesis by gastric scintigraphy. Oesophageal motility disorders were found in 68% and 42% of patients with or without scintigraphic evidence of gastroparesis respectively, suggesting of overlapping gastric and oesophageal neuromuscular disorder. Forty-three per cent of patients with gastroparesis had abnormal oesophageal acid exposure with mean % pH <4.0 of 7.5 in contrast to 38% of those symptomatic controls with normal gastric emptying, with mean %pH <4.0 of 5.4 (NS). Symptoms of epigastric pain, heartburn/regurgitation, bloating, nausea, vomiting, dysphagia, belching and weight loss could not distinguish patients with or without gastroparesis, although weight loss was significantly more prevalent and severe (p<0.002) in patients with gastroparesis. There was no relationship between oesophageal symptoms and motor or pH abnormalities in either groups. Conclusions Irrespective of gastric emptying delay by scintigraphy, patients with symptoms suggestive of gastric neuromuscular dysfunction have a high prevalence of oesophageal motor disorder and pathological oesophageal acid exposure that may contribute to their symptoms and may require therapy. High-resolution oesophageal manometry and pH monitoring are non-invasive and potentially useful in the assessment and management of these patients. PMID:29177065

Background An 82-year-old male presented with a chief complaint of upper abdominal pain. Subsequently, a bezoar and a gastric ulcer were detected by upper gastrointestinal endoscopy. Case presentation The bezoar was dark green in color and extremely hard, having a major axis of 7 cm. After hospitalization, 500–1000 ml/day of Coca-Cola was orally administered continuously for 3 weeks. Conclusion Thereafter, the bezoar decreased in size to a major axis of 4 cm and showed a softening trend. Therefore, lithotripsy was thereafter carried out under endoscopy using forceps.

Rhus tripartitum (sumac) is an Anacardiaceae tree with a wide phytotherapeutic application including the use of its roots in the management of gastric ulcer. In the present study the Rhus tripartitum root barks extract (RTE) was phytochemical studied, in vitro tested for their potential antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and reducing power assay and in vivo evaluated for its ability to prevent ethanol-induced gastric ulcer in rats. The RTE was rich in phenolics, flavonoids, tannins and polysaccharide contents and exhibited a low but not weak in vitro antioxidant activity when compared with (+)-catechin. Pre-treatment with RTE at oral doses 50, 200 and 400 mg/kg body weight was found to provide a dose-dependent protection against ethanol-induced ulcer by averting the deep ulcer lesions of the gastric epithelium, by reducing gastric juice and acid output, by enhancing gastric mucus production by preserving normal antioxidant enzymes activities, and inhibiting the lipid peroxidation. The antiulcerogenic activity of RTE might be due to a possible synergistic antioxidant and antisecretory effects.

The aim of this study was to assess the role of transabdominal ultrasound with cellulose-based oral contrast agent (TUS-OCCA) in the detection and surveillance of gastric ulcer. The study was approved by the institutional review board at Shengjing Hospital of China Medical University. A total of 124 consecutive patients with benign gastric ulcer diagnosed by gastroscopy and biopsy were enrolled. Serial TUS-OCCA (approximately 1 exam every 2 wk) was performed to monitor the effects of treatment, and additional interventions were planned according to the results. TUS-OCCA detected gastric ulcer in 76% of patients (94 of 124). The detection rates for lesions of ≤5 mm, lesions of 5-10 mm, lesions of 10-15 mm and lesions >15 mm were 32% (10 of 31), 77% (27 of 35), 96% (25 of 26) and 100% (32 of 32), respectively. The detection rates for lesions located in the antrum, angle and body were 70%, 84% and 85%, respectively. Among 30 undetected lesions, which ranged 2-13 mm in size, 11 were at the antrum, 9 at the angle, 3 in the body, 6 at the cardia and 1 at the fundus. During the follow-up period, patients underwent a mean of 3.8 TUS-OCCA examinations (range 2-7), and ulcers were healed after 8 wk (range 2-12 wk) of standard therapy in 76 patients. Eighteen patients who did not show improvement after standard therapy underwent repeat gastroscopy with biopsy. Repeat biopsy was positive for gastric cancer in 4 of these: 2 of the remaining 14 were diagnosed with gastric cancer at gastrectomy, and 12 were diagnosed with chronic benign ulcer. These results indicate that serial TUS-OCCA can be used for close monitoring during routine treatment of gastric ulcers that are detectable by TUS-OCCA and that monitoring by TUS-OCCA can guide additional interventions. A non-invasive follow-up program based on TUS-OCCA can also help to detect gastric cancers that have been misdiagnosed as benign ulcers at the initial endoscopic biopsy. Copyright © 2017 The Authors.

Bile acids have been proposed as key mediators of the metabolic effects after bariatric surgery. Currently no reports on bile acid profiles after duodenal switch exist, and long-term data after gastric bypass are lacking. To investigate bile acid profiles up to 5 years after Roux-en-Y gastric bypass and biliopancreatic diversion with duodenal switch and to explore the relationship among bile acids and weight loss, lipid profile, and glucose metabolism. Two Scandinavian University Hospitals. We present data from a randomized clinical trial of 60 patients with body mass index 50-60 kg/m 2 operated with gastric bypass or duodenal switch. Repeated measurements of total and individual bile acids from fasting serum during 5 years after surgery were performed. Mean concentrations of total bile acids increased from 2.3 µmol/L (95% confidence interval [CI], -.1 to 4.7) at baseline to 5.9 µmol/L (3.5-8.3) 5 years after gastric bypass and from 1.0 µmol/L (95% CI, -1.4 to 3.5) to 9.5 µmol/L (95% CI, 7.1-11.9) after duodenal switch; mean between-group difference was -4.8 µmol/L (95% CI, -9.3 to -.3), P = .036. Mean concentrations of primary bile acids increased more after duodenal switch, whereas secondary bile acids increased proportionally across the groups. Higher levels of total bile acids at 5 years were associated with lower body mass index, greater weight loss, and lower total cholesterol. Total bile acid concentrations increased substantially over 5 years after both gastric bypass and duodenal switch, with greater increases in total and primary bile acids after duodenal switch.

The value of aesthetic dentistry has precipitated several developments in the investigation of dental materials related to this field. The free marketing of these products is a problem and it is subject to various interpretations regarding its legality. There are several techniques for tooth whitening, the most used one being the external bleaching. It is the later version of such technique that poses the greatest danger of ingesting the product. The present study analysed the systemic effect of these products when they are swallowed. This experimental study aimed to observe the effects of a tooth whitening product, whose active agent is 6% hydrogen peroxide, on the gastric mucosa of healthy and non-tumour gastric pathology animals. Fifty Wistar-Han rats were used and then distributed into 5 groups, one for control and four test groups in which the bleaching product was administered in animals with and without non-tumour gastric pathology (induced by the administration of 1 sample of 50% ethanol and 5% of drinking water during 6 days) at different times of study by gavage. There was a decrease in body weight in animals of groups handled during the study period, which was most pronounced in IV and VA groups. Changes in spleen weight relative to body weight revealed no statistically significant changes. An analysis of the frequency was performed on the results of macroscopic observation of the gastric mucosa. The gastric mucosa revealed lesions in all manipulated groups, being more frequent in groups III and IV. It appears that there is a synergism when using hydrogen peroxide and 50% ethanol in the same group. Therefore, it seems that there are some signs of toxicity 3 to 4 days after administration of 6% hydrogen peroxide. The prescription of these therapies must be controlled by the clinician and the risks must be minimized.

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.

Gastric cancer is one of the most common malignancies and remains the second leading cause of cancer-related death worldwide. Over 70% of new cases and deaths occur in developing countries. In the early years of the molecular biology revolution, cancer research mainly focuses on genetic alterations, including gastric cancer. Epigenetic mechanisms are essential for normal development and maintenance of tissue-specific gene expression patterns in mammals. Disruption of epigenetic processes can lead to altered gene function and malignant cellular transformation. Recent advancements in the rapidly evolving field of cancer epigenetics have shown extensive reprogramming of every component of the epigenetic machinery in cancer, including DNA methylation, histone modifications, nucleosome positioning, noncoding RNAs, and microRNAs. Aberrant DNA methylation in the promoter regions of gene, which leads to inactivation of tumor suppressor and other cancer-related genes in cancer cells, is the most well-defined epigenetic hallmark in gastric cancer. The advantages of gene methylation as a target for detection and diagnosis of cancer in biopsy specimens and non-invasive body fluids such as serum and gastric washes have led to many studies of application in gastric cancer. This review focuses on the most common and important phenomenon of epigenetics, DNA methylation, in gastric cancer and illustrates the impact epigenetics has had on this field.

Gastric cancer incidence rates are consistently lower in women than men in both high and low-risk regions worldwide. Sex hormones, such as progesterone and estrogen, may protect women against gastric cancer. To investigate the association of menstrual and reproductive factors and gastric cancer risk. These associations were prospectively investigated in 73 442 Shanghai women. After 419 260 person-years of follow-up, 154 women were diagnosed with gastric cancer. Hazard ratios (HR) and 95% confidence intervals (CI) were calculated using Cox proportional hazards models adjusted for age, body mass index, education, income, and cigarette use. No associations were observed between gastric cancer risk and age of menarche, number of children, breast feeding, or oral contraceptive use. In contrast, associations were observed with age of menopause (HR 0.80 per five-year increase in menopausal age, 95% CI 0.66-0.97), years of fertility (participants with less than 30 years of fertility were at increased risk compared with those with 30-36 years of fertility, HR 1.90, 95% CI 1.25-2.90), years since menopause (HR 1.26 per five years, 95% CI 1.03-1.53), and intrauterine device use (HR for users 1.61, 95% CI 1.08-2.39). These results support the hypothesis that female hormones play a protective role in gastric cancer risk.

Force direction patterns promote whole body stability even in hip-flexed walking, but not upper body stability in human upright walking

Directing the ground reaction forces to a focal point above the centre of mass of the whole body promotes whole body stability in human and animal gaits similar to a physical pendulum. Here we show that this is the case in human hip-flexed walking as well. For all upper body orientations (upright, 25°, 50°, maximum), the focal point was well above the centre of mass of the whole body, suggesting its general relevance for walking. Deviations of the forces' lines of action from the focal point increased with upper body inclination from 25 to 43 mm root mean square deviation (RMSD). With respect to the upper body in upright gait, the resulting force also passed near a focal point (17 mm RMSD between the net forces' lines of action and focal point), but this point was 18 cm below its centre of mass. While this behaviour mimics an unstable inverted pendulum, it leads to resulting torques of alternating sign in accordance with periodic upper body motion and probably provides for low metabolic cost of upright gait by keeping hip torques small. Stabilization of the upper body is a consequence of other mechanisms, e.g. hip reflexes or muscle preflexes.

Forced-air warming with upper body blankets has gained high acceptance as a measure for the prevention of intraoperative hypothermia. However, data on heat transfer with upper body blankets are not yet available. This study was conducted to determine the heat transfer efficacy of eight complete upper body warming systems and to gain more insight into the principles of forced-air warming. Heat transfer of forced-air warmers can be described as follows: Qdot;=h. DeltaT. A, where Qdot;= heat flux [W], h=heat exchange coefficient [W m-2 degrees C-1], DeltaT=temperature gradient between the blanket and surface [ degrees C], and A=covered area [m2]. We tested eight different forced-air warming systems: (1) Bair Hugger and upper body blanket (Augustine Medical Inc. Eden Prairie, MN); (2) Thermacare and upper body blanket (Gaymar Industries, Orchard Park, NY); (3) Thermacare (Gaymar Industries) with reusable Optisan upper body blanket (Willy Rüsch AG, Kernen, Germany); (4) WarmAir and upper body blanket (Cincinnati Sub-Zero Products, Cincinnati, OH); (5) Warm-Gard and single use upper body blanket (Luis Gibeck AB, Upplands Väsby, Sweden); (6) Warm-Gard and reusable upper body blanket (Luis Gibeck AB); (7) WarmTouch and CareDrape upper body blanket (Mallinckrodt Medical Inc., St. Luis, MO); and (8) WarmTouch and reusable MultiCover trade mark upper body blanket (Mallinckrodt Medical Inc.) on a previously validated copper manikin of the human body. Heat flux and surface temperature were measured with 11 calibrated heat flux transducers. Blanket temperature was measured using 11 thermocouples. The temperature gradient between the blanket and surface (DeltaT) was varied between -8 and +8 degrees C, and h was determined by linear regression analysis as the slope of DeltaT vs. heat flux. Mean DeltaT was determined for surface temperatures between 36 and 38 degrees C, as similar mean skin surface temperatures have been found in volunteers. The covered area was estimated to be 0.35 m2. Total heat flow from the blanket to the manikin was different for surface temperatures between 36 and 38 degrees C. At a surface temperature of 36 degrees C the heat flows were higher (4-26.6 W) than at surface temperatures of 38 degrees C (2.6-18.1 W). The highest total heat flow was delivered by the WarmTouch trade mark system with the CareDrape trade mark upper body blanket (18.1-26.6 W). The lowest total heat flow was delivered by the Warm-Gard system with the single use upper body blanket (2.6-4 W). The heat exchange coefficient varied between 15.1 and 36.2 W m-2 degrees C-1, and mean DeltaT varied between 0.5 and 3.3 degrees C. We found total heat flows of 2.6-26.6 W by forced-air warming systems with upper body blankets. However, the changes in heat balance by forced-air warming systems with upper body blankets are larger, as these systems are not only transferring heat to the body but are also reducing heat losses from the covered area to zero. Converting heat losses of approximately 37.8 W to heat gain, results in a 40.4-64.4 W change in heat balance. The differences between the systems result from different heat exchange coefficients and different mean temperature gradients. However, the combination of a high heat exchange coefficient with a high mean temperature gradient is rare. This fact offers some possibility to improve these systems.

Dyspepsia in childhood and adolescence: insights and treatment considerations.

Functional dyspepsia (FD) is common in children, with as many as 80% of those being evaluated for chronic abdominal pain reporting symptoms of epigastric discomfort, nausea, or fullness. It is known that patients with persistent complaints have increased comorbidities such as depression and anxiety. The interaction with psychopathologic variables has been found to mediate the association between upper abdominal pain and gastric hypersensitivity. These observations suggest that abnormal central nervous system processing of gastric stimuli may be a relevant pathophysiologic mechanism in FD. Despite increased understanding, no specific therapy has emerged; however, recent nonpharmacological-based options such as hypnosis may be effective. Novel approaches, including dietary manipulation and use of nutraceuticals such as ginger and Iberogast (Medical Futures Inc., Ontario, Canada), may also be considered.

A diospyrobezoar is a type of phytobezoar that is considered to be harder than any other types of phytobezoars. Here, we describe a new treatment modality, which effectively and easily disrupted huge gastric diospyrobezoars. A 41-year-old man with a history of diabetes mellitus was admitted with lower abdominal pain and vomiting. Upper gastrointestinal endoscopy revealed three huge, round diospyrobezoars in the stomach. He was made to drink two cans of Coca-Cola every 6 h. At endoscopy the next day, the bezoars were partially dissolved and turned to be softened. We performed direct endoscopic injection of Coca-Cola into each bezoar. At repeated endoscopy the next day, the bezoars were completely dissolved.

Abstract Rationale: Portal annular pancreas is a rare anatomic variation, where the uncinated process of the pancreas connects with the dorsal pancreas and the pancreas tissue encases the portal vein (PV), superior mesenteric vein (SMV) or splenic vein (SV). Malignancies are quite uncommon in the patients, who have an annular pancreas especially portal annular pancreas. Ectopic common hepatic artery and absence of the celiac trunk (CT) are the other infrequent abnormalities. Patient concerns: A 74-year-old man suffered from upper abdominal and back pain. Diagnoses and Interventions: Contrast enhanced computed tomography indicated a low-density mass in the body of the pancreas. Pathological report showed adenocarcinoma of the body of pancreas after radical antegrade modular pancreatosplenectomy (RAMPS). Outcomes: In the operation, we found the superior vein and portal vein was surrounded by the pancreatic tissue. The left gastric artery and splenic artery originated respectively from abdominal aorta, and celiac trunk was not viewed. In addition, the common hepatic artery was a branch from the superior mesenteric artery. Lessons: In general, this is a novel clinical case of pancreatic carcinoma happening in the portal annular pancreas which was accompanied with aberrant hepatic artery and absence of the celiac trunk at the same time. Confronted with the pancreatic neoplasms, the possibility of coexistent annular pancreas and arterial variations should be considered. PMID:29310347

Circular RNAs (circRNAs) are a new class of noncoding RNAs. However, the expression profile and clinical significance of circRNAs in human gastric cancer is unclear. The global circRNA expression profile in human gastric cancer was measured by circRNA microarray. Hsa_circ_0014717, one of the most downregulated circRNAs in microarray, was selected as a targeted circRNA to explore its levels in gastric tissues and gastric juice. Freeze-thaw experiment and incubation experiment confirmed the stability of gastric juice circRNAs. A total of 308 circRNAs, including 107 (34.74%) upregulated and 201 (65.26%) downregulated circRNAs, were found significantly aberrantly expressed in gastric cancer tissues. The top ten upregulated in gastric cancer tissues were hsa_circ_0035445, hsa_circ_0003789, hsa_circ_0063809, hsa_circ_0074362, hsa_circ_0006282, hsa_circ_0011107, hsa_circ_0084606, hsa_circ_0005556, hsa_circ_0050547, and hsa_circ_0006470, while the top ten downregulated ones were hsa_circ_0007099, hsa_circ_0001897, hsa_circ_0007707, hsa_circ_0008832, hsa_circ_0001546, hsa_circ_0002089, hsa_circ_0004680, hsa_circ_0000154, hsa_circ_0004458, and hsa_circ_0008394. The hot-point chromosomes were chr1, chr2, chr3, chr9, and chr17. Hsa_circ_0014717 was significantly downregulated in 77.2% (74/96) gastric cancer tissues. Its levels in gastric cancer tissues were related to tumor stage (P = 0.037), distal metastasis (P = 0.048), tissue carcinoembryonic antigen (P = 0.001), and carbohydrate antigen 19-9 expression (P = 0.021). More importantly, hsa_circ_0014717 can stably exist in human gastric juice; and its nature meets the requirements of clinical detection. Our study uncovered the circRNA expression profile in human gastric cancer. Moreover, some circRNAs can stably exist in human body fluid, and has the potential to be used as novel biomarkers for the screening of high-risk gastric cancer patients. © 2017 The Authors.

Delayed gastric emptying is one of the reasons why functional dyspepsia (FD) occurs. The 13C-acetate breath test is widely used to evaluate gastric emptying. Nevertheless, the standard value of 13C-acetate breath test has not taken into account the gender difference of gastric emptying among healthy individuals. The main aim of this study was to readjust the standard value of 13C-acetate breath test in the light of gender differences. In addition, we clarified the prevalence and clinical characteristics of delayed gastric emptying in patients with FD using the modified standard values of 13C-acetate breath test. Fifty-two healthy individuals and 126 patients with patients with FD were enrolled. Gastric emptying was evaluated by the 13C-acetate breath test. The cut-off points of Tmax for the diagnosis of delayed gastric emptying were determined on the basis of results from healthy individuals making a distinction of genders. Gastroesophageal reflux symptoms, dyspeptic symptoms, scores of anxiety and depression, age, body mass index (BMI), smoking and alcohol consumption were compared between the delayed gastric emptying group and the non-delayed gastric emptying group. Since gastric emptying was delayed in healthy women compared with that in healthy men (Tmax, 53.6 ± 19.3 vs. 42.7 ± 16.9 min, p = 0.04), we set the cut-off points of Tmax at 60 min in men and at 75 min in women. In patients with FD, the prevalence of delayed gastric emptying was not different between men and women with the modified standard values of 13C-acetate breath test. (31.0 vs. 27.4%, p = 0.68). BMI was lower in the delayed gastric emptying group than in the non-delayed group among the male patients. Reflux symptoms were more severe in delayed gastric emptying group than in the non-delayed group among the female patients. The standard values of 13C-acetate breath test should be modified bearing the gender difference in mind. It provides us more appropriate information to understand the mechanisms of FD. © 2016 S.

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.

To develop an indirect enzyme-linked immunosorbent assay (ELISA) for measuring class-pi glutathione S-transferase (GST) in plasma, and tissue biopsies obtained from upper gastrointestinal cancer (UGI Ca) patients. GST activity and GST-pi concentration were detected in normal human squamous esophageal epithelium, normal gastric cardia and their corresponding malignant tumor biopsies. Plasma GST was significantly higher (p < 0.05) in UGI Ca patients as compared to those obtained from normal individuals. Plasma GST-pi concentration in normal subjects was 6.6 +/- 1.9 ng/mg protein, whereas it was higher in UGI Ca patients (esophageal, 10.0 +/- 1.8; gastric, 10.7 +/- 1.7 ng/mL, p

Background Whether and how sex and age affect bariatric-surgery outcome is poorly understood. Estrogens regulate body composition in women and animals and increased weight loss in a rodent model of gastric bypass, suggesting that premenopausal women may lose more weight following bariatric surgery. Methods 1,356 female gastric-bypass or gastric-banding patients were retrospectively grouped as 20-45 y old (presumptively premenopausal; n = 1199) and 55-65 y old (presumptively postmenopausal; n = 157). Mixed-model ANCOVA followed by Bonferroni-corrected t-tests were used to categorically test the effect of age on percent excess body weight loss (%EBWL) at 1 and 2 y post-surgery, controlling for preoperative EBW and surgery type. Age effects were also tested dimensionally in all women and in 289 male patients. Results 20-45 y-old women showed greater %EBWL 1 and 2 y post-surgery than 55-65 y-old women (p’s < 0.0005). No age effect was detected in 20-25 vs. 30-35, 30-35 vs. 40-45, or 20-25 vs. 40-45 y-old women (p’s > 0.2) This age effect was detected only after gastric banding, with 20-45 y-old women losing ~7 kg more than 55-65 y-old women after 2 y. Dimensional analysis confirmed a significant inverse effect of age on bariatric surgery outcome in women, but did not detect any effect in men. Conclusions Results indicate that 55-65 y-old women lose less weight than 20-45 y-old women in the initial 2 y after bariatric surgery, especially gastric banding; this may be mediated by age- or menopause-associated changes in physical activity, energy expenditure, or energy intake.

A reproducible Roux-en-Y gastric bypass (RYGB) model in mice is needed to study the physiological alterations after surgery. Male C57BL6 mice weighing 29.0 ± 0.8 g underwent either RYGB (n = 14) or sham operations (n = 6). RYGB surgery consisted of a small gastric pouch (~2 % of the initial stomach size), a biliopancreatic and alimentary limb of 10 cm each and a common channel of 15 cm. Animals had free access to standard chow in the postoperative period. Body mass and food intake were recorded for 60 days. Bomb calorimetry was used for faecal analysis. Anatomical rearrangement was assessed using planar X-ray fluoroscopy and computed tomography (CT) after oral Gastrografin® injection. RYGB surgery led to a sustained reduction in body weight compared to sham-operated mice (postoperative week 1: sham 27.8 ± 0.7 g vs. RYGB 26.5 ± 1.0 g, p = 0.008; postoperative week 8: sham 30.7 ± 0.8 g vs. RYGB 28.4 ± 1.1 g, p = 0.003). RYGB mice ate less compared to shams (sham 4.6 ± 0.2 g/day vs. RYGB 4.3 ± 0.4 g/day, p < 0.001). There were no differences in faecal mass (p = 0.13) and faecal energy content (p = 0.44) between RYGB and shams. CT scan demonstrated the expected anatomical rearrangement without leakage or stenosis. Fluoroscopy revealed rapid pouch emptying. RYGB with a small gastric pouch is technically feasible in mice. With this model in place, genetically manipulated mouse models could be used to study the physiological mechanisms involved with metabolic changes after gastric bypass.

Anastomotic stenosis presents as one of the most common late complications in the postoperative period after bariatric surgery. It is often diagnosed by upper gastrointestinal series (UGIS) and/or upper endoscopy (UE). The aim of this study was to determine whether a correlation exists between the Gastrografin UGIS and UE findings in the determination of gastrojejunal anastomotic strictures after Roux-en-Y gastric bypass (RYGB). Between July 2001 and October 2003, all medical records of patients who underwent RYGB at our institution were retrospectively reviewed. The medical records of patients who underwent UE because of symptoms suggestive of gastric outlet obstruction and those of patients who were initially evaluated by Gastrografin UGIS before UE were evaluated further. Of 535 morbidly obese patients who underwent RYGB, 52 (9.7%) had UE and were included in this study. The mean number of UEs performed per patient was 2.67. Of these 52 patients, 30 underwent Gastrografin UGIS before UE. The mean diameter of the anastomosis on the first UE was 5.97 mm and on Gastrografin UGIS was 6.83 mm. A good correlation was found between the Gastrografin UGIS and UE findings using Pearson's correlation coefficient (0.44, P = .02) and single linear regression analysis using the endoscopic diameter as the outcome and radiographic findings as the predictor (beta = 0.27, P = .025, 95% confidence interval 0.30-0.49). In our study, the Gastrografin UGIS findings correlated positively with the endoscopic gastrojejunal anastomosis findings in patients with anastomotic stricture who had undergone RYGB.

To evaluate 30-day safety and efficacy of superselective embolization for arterial upper gastrointestinal bleeding (UGIB) using N-butyl cyanoacrylate (NBCA). This single-center retrospective 10-year study included 152 consecutive patients with UGIB (gastric, n = 74; duodenal, n = 78) who underwent embolization with NBCA for angiographically positive arterial bleeding. The primary endpoint was clinical success rate defined as achievement of hemostasis without rebleeding or UGIB-related mortality within 30 days after embolization. Mean systolic blood pressure and heart rate were 121.2 mm Hg ± 27.4 and 97.9 beats/minute ± 22.5; 31.1% of patients needed intravenous inotropes, and 36.6% had coagulopathy. The etiology of bleeding was ulcer (80.3%) or iatrogenic injury (19.7%). Statistical analysis was performed to identify predictive factors for outcomes. Technical success rate was 100%. Clinical success, 1-month mortality, and major complication rates were 70.4%, 22.4%, and 0.7%. There were significant differences in the clinical success rates between gastric and duodenal bleeding (79.4% vs 62.2%; P = .025). The need for intravenous inotropes at the time of embolization was a significant negative predictive factor in both gastric (odds ratio [OR] = 0.091, P = .004) and duodenal (OR = 0.156, P = .002) bleeding. The use of a microcatheter with a smaller tip (2 F) was associated with better outcomes in duodenal bleeding (OR = 7.389, P = .005). Superselective embolization using NBCA is safe and effective for angiographically positive arterial UGIB. Copyright © 2017 SIR. Published by Elsevier Inc. All rights reserved.

Helicobacter pylori (HP)-associated chronic gastritis can cause mucosal atrophy and intestinal metaplasia, both of which increase the risk of gastric cancer. The accurate diagnosis of HP infection during routine medical checks is important. We aimed to develop a convolutional neural network (CNN), which is a machine-learning algorithm similar to deep learning, capable of recognizing specific features of gastric endoscopy images. The goal behind developing such a system was to detect HP infection early, thus preventing gastric cancer.  For the development of the CNN, we used 179 upper gastrointestinal endoscopy images obtained from 139 patients (65 were HP-positive: ≥ 10 U/mL and 74 were HP-negative: < 3 U/mL on HP IgG antibody assessment). Of the 179 images, 149 were used as training images, and the remaining 30 (15 from HP-negative patients and 15 from HP-positive patients) were set aside to be used as test images. The 149 training images were subjected to data augmentation, which yielded 596 images. We used the CNN to create a learning tool that would recognize HP infection and assessed the decision accuracy of the CNN with the 30 test images by calculating the sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve (AUC).  The sensitivity and specificity of the CNN for the detection of HP infection were 86.7 % and 86.7 %, respectively, and the AUC was 0.956.  CNN-aided diagnosis of HP infection seems feasible and is expected to facilitate and improve diagnosis during health check-ups.

In this paper we are reporting one case of exsanguinating upper gastrointestinal tract (GIT) bleed requiring massive blood transfusion and immediate life saving surgery. A 30 years old female, 12 weeks pregnant was referred to our hospital from the earth-quake affected area of Kashmir with history of upper abdominal pain, haematemesis and melaena for one week. After stabilizing the patient, upper gastro-intestinal endoscopy was performed. It revealed gastric ulcer just distal to the gastro-esophageal junction on the lesser curvature. Biopsy from the ulcer edge led to profuse spurting of the blood and patient went into state of shock. Immediate resuscitation led to rebleeding and recurrence of post haemorrahagic shock. The patient was immediately explored and total gastrectectomy with splenectomy concluded as life saving procedure. A review of literature was conducted to make this report possible.

Morbid obesity is a serious health problem associated to a significant reduction in life expectancy. To evaluate the anthropometric and metabolic changes observed in obese patients, 3, 6 and 12 months after laparoscopic Roux-en-Y gastric bypass surgery and the complications associated with the procedure. Retrospective study that included 128 consecutive obese patients submitted for bariatric surgery at the INCMNSZ (2004-2006). Their mean age was 38 +/- 10 years, 83% were women with a BMI of 48 +/- 6 Kg/m2. 65% were hypertensives, 55% had hypertriglyceridemia and 34% diabetes. A year after surgery all patients had at least reduced 20% their body weight and the percentage of excess body weight loss was 73%. The prevalence of hypertension, hypertrigliceridemia and diabetes was reduced to 24%, 17% and 12%, respectively (p < 0.001). Four patients died (3%), all of them had a leak of the anastomosis and intra-abdominal abscess. One died because pulmonary embolism, another with a myocardial infarction (after surgical reinterventions) and the other two with sepsis. Laparoscopic Roux-en-Y gastric bypass surgery in morbid obese patients favors significant reductions in body weight and associated co morbidities. This surgery is not free of complications and mortality, reason why it must be done only by surgical and interdisciplinary groups with experience in these procedures.

Althaea officinalis Linn. (Malvaideae) flower is commonly used in folk medicine in Lebanon and neighboring countries. Although most of the studies have been conducted on the mucilage-rich roots, little is known about the flower. This study investigates the potential role of aqueous extract of Althaea officinalis flower in lipemia, gastric ulcer, inflammation, and platelet aggregation using the rat model. Blood lipid profile and liver function were assessed after 1 month of extract intake via drinking water. Anti-inflammatory activity was tested against acute and chronic inflammation induced by carrageenan and formalin, respectively. Antiulcer activity was evaluated using ethanol-induced gastric ulcer. Antiplatelet activity was investigated in vitro using the adenosine 5'-diphosphate (ADP)-induced platelet aggregation bioassay. The 50 mg/kg body weight dose resulted in significant increase in serum HDL cholesterol level with no effects on stool cholesterol and triacylglycerol. Increasing the dose to 500 mg/kg body weight caused a significant decrease in stool water content. No adverse effect on liver enzymes was observed. Significant anti-inflammatory (acute and chronic inflammation) and antiulcerogenic activities were observed at all used doses (50, 100, and 250 mg/kg body). Time-dependent inhibition of platelet aggregation was demonstrated at 500 µg/ml concentration. The aqueous extract of Althaea officinalis flower demonstrated potential benefits in lipemia, inflammation, gastric ulcer, and platelet aggregation with no visible adverse effect.

DNA methylation is associated with "field defect" in the gastric mucosa. To characterize "field defect" morphologically, we examined DNA methylation of non-neoplastic gastric mucosa in relation to their morphology seen by narrow-band imaging (NBI) with magnifying endoscopy. Magnifying NBI of non-neoplastic gastric body was classified as follows: normal-small and round pits with uniform subepithelial capillary networks; type 1-a little enlarged round pits with indistinct subepithelial capillary networks; type 2-remarkably enlarged pits with irregular vessels; and type 3-clearly demarcated oval or tubulovillous pits with bulky coiled or wavy vessels. Methylation of nine candidate genes (MYOD1, SLC16A12, GDNF, IGF2, MIR 124A1, CDH1, PRDM5, RORA and MLF1) were determined by bisulfite pyrosequencing. Infinium HumanMethylation450 array was used to characterize the methylation of >450,000 CpG sites. Mean Z score methylation of nine genes positively correlated with the changes of mucosal patterns from normal to types 1, 2, and 3 (P < 0.0001). Genome-wide analysis showed that development of mucosal patterns correlated with methylation accumulation especially at CpG islands. Genes with promoter CpG islands that were gradually methylated with the development of mucosal patterns significantly enriched the genes involved in zinc-related pathways. The results indicates that gastric mucosal morphology predicts a "field defect" in this tissue type. Accumulation of DNA methylation is associated with "field defect" in the non-neoplastic gastric mucosa. Endoscopic identification of "field defect" has important implications for preventing gastric cancer. Our results suggest that magnifying NBI of gastric mucosal morphology predicts a "field defect" in the gastric mucosa.

Chronic gastritis frequently progresses into precancerous intestinal metaplasia and intraepithelial neoplasia lesions. Rebamipide is a free radical scavenger and we assessed its efficacy on clinical symptoms, gastric mucosal lesions, pathologic grade, and immunohistochemistry in chronic gastritis patients. 178 eligible patients were randomized into treatment and control groups. Both groups followed an optimized lifestyle for 26 weeks, but the treatment group was additionally medicated with rebamipide 0.1 g three times per day. Upper gastrointestinal endoscopy was performed in all patients to evaluate the severity of gastritis by the Modified Lanza Scoring (MLS) and histological changes were evaluated by the Updated Sydney System Score (USSS). Gastric mucosa immunohistochemistry in the treatment group was performed using the intestinal metaplasia markers caudal type homeobox transcription factor 2 (CDX2) and trefoil factor 3 (TFF3) detection. There were significant outcome differences between the treatment and control groups regarding the clinical symptom scores (2.62 ± 1.86 vs. 1.55 ± 1.61, P = 0.0001), gastric mucosal lesion scores (0.57 ± 1.05 vs. 0.16 ± 0.90, P = 0.002), and inflammation (P < 0.05). Only in the treated patients were the rates of intestinal metaplasia (P = 0.017 vs. P = 0.123) and low-grade intraepithelial neoplasia (P = 0.005 vs. P = 0.226) significantly reduced after 26 weeks. The percentages of CDX2 (31.5 vs. 15.7%, P = 0.021) and TFF3 (44.9 vs. 25.8%, P = 0.012) expressing gastric mucosa cells were significantly lower after rebamipide medication than pre-treatment values. Rebamipide improved the clinical symptoms, gastric mucosal lesions, and pathological grades of chronic gastritis patients and decreased the expression rates of CDX2 and TFF3 in gastric cells.

This study was conducted to assess the relationship between occurrence of gastric cancer and peptic ulcer, and the presence of H. pylori cagA gene and anti-CagA IgG, and to estimate the value of these antibodies in detecting infection by cagA gene-positive H. pylori strains in Saudi patients. The study included 180 patients who were subjected to upper gastrointestinal endoscopy in Taif province and Western region of Saudi Arabia (60 gastric cancer, 60 peptic ulcer, and 60 with non-ulcer dyspepsia). Gastric biopsy specimens were obtained and tested for H. pylori infection by rapid urease test and culture. PCR was performed on the isolated strains and biopsy specimens for detection of the cagA gene. Blood samples were collected and tested for CagA IgG by ELISA. H. pylori infection was detected among 72.8% of patients. The cagA gene and anti-CagA IgG were found in 63.4% and 61.8% of H. pylori-infected patients, respectively. They were significantly (p < 0.01) higher in patients with gastric cancer and peptic ulcer compared with those with non-ulcer dyspepsia. Detection of the CagA IgG was 91.6% sensitive, 89.6% specific, and 90.8% accurate compared with detection of the cagA gene. Its positive and negative predictive values were 93.8% and 86%, respectively. The study showed a significant association between the presence of the cagA gene and gastric cancer and peptic ulcer disease, and between anti-CagA IgG and the cagA gene in Saudi patients. However, a further larger study is required to confirm this finding.

Helicobacter pylori (H. pylori) infection causes chronic gastritis and is a major risk factor for duodenal and gastric ulceration, gastric adenocarcinoma, and primary gastric lymphoma. Increased gastric bacterial density may lead to increased levels of inflammation and epithelial injury. 1) To study the effect of H. pylori density by histological changes in stomach. 2) To study the effect of H. pylori density on the efficacy of standard triple drug eradication treatment. 3) To study the effect of H. pylori density on the complication related to H. pylori. All the patients visiting gastroenterology OPD with the symptoms of dyspepsia not responding to proton pump inhibitor or having alarm symptoms were subjected to upper GI endoscopy and biopsy. If H. pylori was present they were included in the study. The patients were given standard 14 day triple antibiotic combination for H. pylori eradication. H. pylori eradication was confirmed by urea breath test after six weeks of completion of treatment. Out of 250 patients screened, 120 patients enrolled in the study. On clinical history 41.5% patients had symptoms of heart burn where as 63.3% patients had dyspeptic symptoms. Success rate of anti H. pylori triple drug therapy was 80%. Rate of eradication was significantly lower among the patients with higher H. pylori density (p < 0.05) on histopathology by Sydney classification. Duodenal ulcer, Gastric ulcer and gastric erosion were noted in higher frequencies among the patients with higher H. pylori density (p < 0.05). H. pylori density by histopathology correlates with the complication related to H. pylori i.e. duodenal ulcer, reflux esophagitis and antral erosions. It also correlates with the success of the standard triple drug eradication treatment.

Background and study aims  Screening for esophageal and gastric varices is indicated for patients with portal hypertension or cirrhosis. Typically, conventional endoscopy is used; however, the need for sedation increases the costs and risks, especially in cirrhotic patients. Use of transnasal endoscopy with an ultrathin endoscope enables study of the upper gastrointestinal tract without the need for sedation. The objective of this study is to evaluate the feasibility of transnasal endoscopy in screening for esophageal and gastric varices in patients with chronic liver disease. Patients and methods  This was a prospective study in which transnasal endoscopy was carried out in patients with cirrhosis or portal hypertension who had indications for screening of esophageal and gastric varices. The following variables were evaluated: demographical data, duration of procedure, patient tolerance and acceptance, adverse events (AEs), endoscopic findings and interobserver agreement related to portal hypertension alterations ( kappa index). Results  A total of 50 patients entered the study. The most common cause of liver disease was chronic viral hepatitis (66 %). Among the cirrhotic patients, most of the patients were Child-Pugh A (74 %). In 5 patients (10 %), nasal intubation was not possible. Two patients (4 %) experienced minor epistaxis. Tolerance was excellent or good in 92 % according with a visual analogic scale. In 16 patients (32 %), esophageal varices were detected and in 2 patients (4 %) gastric varices were detected. The mean duration of the procedure was 7 minutes. Conclusions  Transnasal endoscopy is feasible, effective and well tolerated for screening of esophageal and gastric varices in patients with chronic liver disease. It can be performed in outpatient clinics safely and without the use of sedation. PMID:28691048

Peptic ulcer disease is a frequent pathological condition. In the last few years there have been reports describing changes in its epidemiology and its association with Helicobacter pylori infection. To describe epidemiological characteristics of peptic ulcers during the study period from January 2000 through December 2005 in Hospital Daniel Carrion. Cross sectional analitical study. All patients with an endoscopic diagnosis of peptic ulcer were included. Patients with gastric cancer or previous surgery were excluded. Data were processed using the SPSS 9.0 software. We reviewed 10,819 endoscopy reports with 899 peptic ulcer cases diagnosed during the study period. 67.8% were male, age average 54 years. Age was higher in females (59.8 y), as was in those with gastric and pyloric ulcers (68.7 y). Most frequent endoscopic indications were upper gastrointestinal bleeding (53.3%) and dyspepsia (43.8%). Duodenal location was the most frequent (49.5%) although in recent years gastric ulcers have become more prevalent. Gastric ulcers were more commonly located in the antrum lesser curvature, while duodenal ulcers were located in the anterior wall of the duodenal bulb. Gastric ulcers were larger in size and more in number than duodenal ones. Helicobacter pylori was present in 65.3% of all ulcers, 74.3% for duodenal and 55.4% for gastric ulcers. Prevalence of peptic ulcers during the study period was 83.09 cases per 1,000 endoscopies. Duodenal ulcers were the most frequent although there is a decline in the last years. There is also a decrease in the frequency of Helicobacter pylori infection as compared to what is usually described.

Duodenogastric reflux in Chagas' disease

Increased duodenogastric reflux has been recognized as a cause of gastric mucosa damage. The frequent finding of bile-stained gastric juice and a suggested higher frequency of lesions of the gastric mucosa in patients with Chagas' disease, which is characterized by a marked reduction of myenteric neurons, suggest that impairment of intrinsic innervation of the gut might be associated with increased duodenogastric reflux. Duodenogastric bile reflux was quantified after intravenous injection of 99mtechnetium-HIDA, in 18 patients with chronic Chagas' disease, 12 controls, and 7 patients with Billroth II gastrectomy. All but one of the chagasic patients were submitted to upper digestivemore » tract endoscopy. High reflux values (greater than or equal to 10%) were detected both in chagasic patients and in the controls, but the values for both groups were significantly lower (P less than 0.01) than those obtained for Billroth II patients (median: 55.79%; range: 12.58-87.22%). Reflux values tended to be higher in the Chagas' disease group (median: 8.20%; range: 0.0-29.40%) than in the control group (median: 3.20%; range: 0.0-30.64%), with no statistical difference between the two groups (P greater than 0.10). Chronic gastritis was detected by endoscopy in 12 chagasic patients, benign gastric ulcer in 2 patients, and a pool of bile in the stomach in 11 patients. However, neither the occurrence of gastric lesions nor the finding of bile-stained gastric juice was associated with high reflux values after (99mTc)HIDA injection. This study suggests that lesions of the intramural nervous system of the gut in Chagas' disease do not appear to be associated with abnormally increased duodenogastric reflux.« less

The aim of this study was to detect the presence of Helicobacter pylori and its virulent cagA genes in the oral cavity of individuals with upper gastric diseases. Sixty-two individuals (42+/-2.3 years) with dispepsy symptoms, referred for gastroscopy and who were H. pylori positive in the gastric biopsy, were recruited and separated in two groups: case group-individuals with gastric disease (n = 30); control group-individuals with no gastric disease (n = 32); saliva, dental plaque and biopsy samples were collected from all individuals. Oral and biopsy samples were analyzed by PCR using specific primers for H. pylori 16S ribosomal and cagA genes. PCR products were sequenced for DNA homology confirmation. H. pylori was detected neither in dental plaque nor in saliva in the control group. In the case group H. pylori DNA was detected in 16/30 (53.3%) saliva samples and in 11/30 (36.6%) dental plaque samples. The cagA gene was detected in 13/30 (43.3%) gastric biopsies, in 7/16 (43.8%) saliva samples, and in 3/11 (27.3%) dental plaque samples. Eighteen (60.0%) individuals in the case group were H. pylori positive both in oral and biopsy samples, and 8 (26.6%) of those were positive for cagA-H. pylori DNA. H. pylori and its virulent clone showed a higher prevalence in the oral cavity of individuals in the case group than in the control group (p < 0.05). Our results suggest that dental plaque and saliva may serve as temporary reservoir for H. pylori and its virulent cagA variant in individuals with gastric disease.

The metastasis of malignant tumors to the spleen is rare, and only a small percentage of cases can be treated surgically, as splenic metastases generally occur in the context of multivisceral metastatic cancer at a terminal stage. We report a rare case of metachronous solitary splenic metastasis arising from early gastric cancer. A 75-year-old man was initially referred to our hospital for examination of gastric cancer, diagnosed at a medical check-up. Esophagogastroduodenoscopy showed a slightly elevated lesion with a central irregular depression in the upper-third of the stomach. Biopsy specimens of the lesion showed a moderately-differentiated adenocarcinoma, and abdominal computed tomography showed no evidence of distant metastases. Endoscopic submucosal dissection was performed, with histological confirmation of a moderately-differentiated adenocarcinoma invading the submucosal layer. The patient subsequently underwent laparoscopic total gastrectomy with regional lymph node dissection, resulting in no residual carcinoma and no lymph node metastasis. Computed tomography, 28 months later, showed a well-defined mass measuring 4.2 cm in diameter in the spleen, and the patient underwent a splenectomy, since there was no evidence of further metastatic lesions in any other organs. Histological examination confirmed the diagnosis of a poorly-differentiated adenocarcinoma originating from the previous gastric cancer. The patient was alive 2 months after surgical resection of the splenic metastasis without any recurrence. To the best of our knowledge, this is only the second case of a solitary splenic metastasis from early gastric cancer to be reported in the English literature. The present case suggests surgical resection may be the preferred treatment of choice for patients with a solitary splenic metastasis from gastric cancer.

Neuroendocrine tumors are relatively rare neoplasms arising from neuroendocrine cells that are distributed throughout the body and are predominant in the gastrointestinal tract. This report describes benign, well-differentiated gastric neuroendocrine tumors in three captive snow leopards (Panthera uncia). All tumors were well circumscribed, were within the gastric mucosa or submucosa, and had histologic and immunohistochemical features of neuroendocrine tumors. Histologic features included packeted cuboidal to columnar epithelial cells that were arranged in palisades or pseudorosettes and contained finely granular cellular cytoplasm with centrally placed, round nuclei. Cytoplasmic granules of neoplastic cells strongly expressed chromogranin A, variably expressed neuron-specific enolase, and did not express synaptophysin or gastrin. Each leopard died or was euthanatized for reasons unrelated to its tumor.

It has been shown that metastases to the thyroid from extrathyroidal malignancies occur as solitary or multiple nodules, or may involve the whole thyroid gland diffusely. However, diffuse metastasis of gastric cancer to the thyroid is extremely rare. Here, we report a case of a 74-year-old woman with diffuse infiltration of gastric adenocarcinoma (signet-ring-cell carcinoma/poorly differentiated adenocarcinoma) cells in the thyroid. The pathological diagnosis was made based on upper gastrointestinal endoscopy with biopsy and fine-needle aspiration cytology of the thyroid. An 18F-FDG PET/CT revealed multiple lesions with increased uptake, including the bilateral thyroid gland. On thyroid ultrasound examination, diffuse enlargement with internal heterogeneity and hypoechoic reticular lines was observed. On color Doppler imaging, a blood-flow signal was not detected in these hypoechoic lines. These findings were similar to those of diffuse metastases caused by other primary cancers, such as lung cancer, as reported earlier. Therefore, the presence of hypoechoic reticular lines without blood-flow signals is probably common to diffuse thyroid metastasis from any origin and an important diagnostic finding. This is the first report to show detailed ultrasound findings of diffuse gastric cancer metastasis to the thyroid gland using color Doppler.

We report the rare case of a 72-year-old man with double cancers (gastric adenocarcinoma and Hodgkin's lymphoma) with collision between gastric adenocarcinoma and Hodgkin's lymphoma. Abdominal computed tomography showed increased wall thickness in the fundus region of the stomach and multiple lymph node swellings in the lesser curvature, periceliac and left cardial regions. Upper gastrointestinal endoscopy showed an ulcer approximately 5 cm in diameter with a malignant appearance in the fundus region of the stomach. On histopathologic examination, two completely different tumors were recognized in the stomach. One tumor was a poorly differentiated adenocarcinoma characterized by poorly developed tubular structures associated with prominent lymphoid infiltration of the stroma. The other tumor was found to have proliferated in the wall of the stomach, with diffuse granulomatous lesions and bordering the adenocarcinoma. Large atypical lymphoid cells with prominent nucleoli and enlarged mononuclei or multinuclei were seen in the latter tumor. Hodgkin's lymphoma was also found in the swollen lesser curvature lymph nodes. As a result, gastric adenocarcinoma and metastasis of Hodgkin's lymphoma were collided in the stomach. In conclusion, this case might be helpful in exploring the occurrence mechanism of tumor collision between lymphoma and carcinoma.

AIM: To evaluate the relationship of Helicobacter pylori infection to reflux esophagitis (RE), Barrett’s esophagus (BE) and gastric intestinal metaplasia (IM). METHODS: RE, BE and gastric IM were determined by upper endoscopy. Patients were divided into 2 groups; those with squamocolumnar junction (SCJ) beyond gastroesophageal junction (GEJ) ≥ 3 cm (group A), and those with SCJ beyond GEJ < 3 cm (group B). Biopsy specimens were obtained endoscopically from just below the SCJ, gastric antrum along the greater and lesser curvature. Pathological changes and H pylori infection were determined by HE staining, Alcian blue staining and Giemsa staining. RESULTS: The prevalence of H pylori infection was 46.93%. There was no difference in the prevalence between males and females. The prevalence of H pylori infection decreased stepwise significantly from RE grade I to III. There was no difference in the prevalence between the two groups, and between long-segment and short-segment BE. In distal stomach, prevalence of H pylori infection was significantly higher in patients with IM than those without IM. CONCLUSION: There is a protective role of H pylori infection to GERD. There may be no relationship between H pylori infection of stomach and BE. H pylori infection is associated with the development of IM in the distal stomach. PMID:14991936

Patients with chronic calorie insufficiency commonly suffer from upper gastrointestinal dysfunction and consequent dyspeptic symptoms, which may interfere with their nutritional rehabilitation. To investigate the relationship between gastric dysfunction and feeding behavior, we exposed mice to chronic caloric restriction and demonstrated gastric motor abnormalities in them. Gastric dysmotility is typically associated with dyspeptic symptoms but sensations cannot be directly assessed in animal models. Therefore, as an initial step toward establishing measurable correlates of postprandial symptoms in small animals, we have attempted to characterize central responses to food intake by positron emission tomography-computerized microtomography (PET-CT) in normal and calorically restricted mice. Animals consumed a standard test meal after an overnight fast before receiving 2-deoxy-2[18F]fluoro-D-glucose tracer. The same mice were also scanned in the fasting state on a separate day. We were able to bring the fed and fasting PET volume images into spatial registration with each other and with an MR-derived atlas of the mouse brain, so that the differences in uptake between the two states could be mapped quantitatively against the neuroanatomic regions of the atlas. Our approach is suitable for studying the effects of gastric dysmotilities on central responses to feeding.

Gastric emptying of cold beverages in humans: effect of transportable carbohydrates.

Eight healthy subjects, aged 39.0 ¿ 2.4 years, consumed four 6% carbohydrate-electrolyte solutions containing either one (glucose or fructose) or two transportable carbohydrates in single (glucose + fructose) or bound (sucrose) forms. Solution osmolalities ranged from 250 to 434 mOsm/kg H2O. The test solutions were ingested at rest in the amount of 6 ml/kg of body weight at a temperature of 12 ¿C. Gastric emptying rate was measured by repeated aspirations via a nasogastric tube using the modified George double-sampling technique. The intragastric temperature was determined by a temperature probe attached to the nasogastric tube. There were no significant differences in gastric emptying rates and gastric volumes among the solutions. Intragastric temperature dropped from 36.5 ¿C to 23.3 ¿ 3 ¿C immediately after beverage ingestion but recovered to above 30 ¿C within 5 min. These data suggest that the gastric emptying rate of the specified beverages is not affected by the number and type of carbohydrates or by solution osmolalities within the tested range. Within 5 min after ingestion, cold beverages are warmed to above 30 C in the stomach. This infers that the effect of cold solution temperature on gastric emptying rate is likely to be small and transitory.

We examined the effects of surgically and gastrically implanted radio transmitters (representing 2.3-5.5% of body weight) on the growth and feeding behavior of 192 juvenile chinook salmon Oncorhynchus tshawytscha (114-159 mm in fork length). Throughout the 54-d study, the 48 fish with transmitters in their stomachs (gastric fish) consistently grew more slowly than fish with surgically implanted transmitters (surgery fish), fish with surgery but no implanted transmitter (sham-surgery fish), or fish exposed only to handling (control fish). Growth rates of surgery fish were also slightly impaired at day 21, but by day 54 they were growing at rates comparable with those of control fish. Despite differences in growth, overall health was similar among all test fish. However, movement of the transmitter antenna caused abrasions at the corner of the mouth in all gastric fish, whereas only 22% of the surgery fish had inflammation around the antenna exit wound. Feeding activity was similar among groups, but gastric fish exhibited a coughing behavior and appeared to have difficulty retaining swallowed food. Because growth and feeding behavior were less affected by the presence of surgically implanted transmitters than by gastric implants, we recommend surgically implanting transmitters for biotelemetry studies of juvenile chinook salmon between 114 and 159 mm fork length.

In this chapter, we describe a method for the induction of stomach organoids from mouse embryonic stem (ES) cells. We used an embryoid body-based differentiation method to induce gastric primordial epithelium covered with mesenchyme and further differentiate it in Matrigel by 3D culture. The differentiated organoid contains both corpus- and antrum-specific mature gastric tissue cells. This protocol may be useful for a variety of studies in developmental biology and disease modeling of the stomach.

The incidence of gastric cancer (GC) arising in the upper third of the stomach, including the cardia or gastroesophageal junction (GEJ), has increased in the last decades due to established etiological risk factors such as diet, obesity, and gastroesophageal reflux. We conducted a systematic review and meta-analysis to determine the prognostic role of site of origin in patients with proximal versus distal GC. We conducted a search of the PubMed, Cochrane Library, SCOPUS, Web of Science, EMBASE, Google Scholar, LILACS, and CINAHL databases from inception to September 2016. Studies reporting data on the independent prognostic effect of site in GC and comparing overall survival (OS) in proximal versus distal tumors were eligible. Data were pooled using OS hazard ratios (HRs) of proximal versus distal GC according to fixed- or random-effect model. Overall, 50 studies including 128,268 patients were identified. Cancers located in the upper third of the stomach were associated with a significantly increased risk of all-cause mortality (HR 1.31, 95% confidence interval [CI] 1.17-1.46, p < 0.001, I 2  = 91%). After exclusion of GEJ tumors, prognosis was worse for pure cardia location (HR 1.39, 95% CI 1.22-1.58, p < 0.001, I 2  = 61%) compared with proximal or upper-third GCs without a specific subsite definition (HR 1.18, 95% CI 1.01-1.37, p = 0.04, I 2  = 91%). Location of the primary GC in the upper third of the stomach, particularly at the GEJ/cardia, should be acknowledged as an important prognostic factor. Based on these results, more effective treatment strategies for proximal GCs are needed.

Passive video capsule endoscopy is the criterion standard for small-bowel exploration but cannot be used for the large gastric cavity. We report the first blinded comparative clinical trial in humans comparing a magnetically guided capsule endoscope (MGCE) and a conventional high-definition gastroscope. To assess the potential of gastric examination with a guided capsule. Blinded, nonrandomized comparative study. Single endoscopy center. The trial involved 61 patients included in a blinded capsule and gastroscopy comparative study. MGCE examination was performed 24 hours after patients had undergone gastroscopy. To remove food residue or mucus, patients drank 900 mL of water in 2 portions. Then to provide the air-water interface required by the guidance system, they drank 400 mL of water at 35°C. Visualization of the gastric pylorus, antrum, body, fundus, and cardia was evaluated as complete in 88.5%, 86.9%, 93.4%, 85.2%, and 88.5% of patients, respectively. Of gastric lesions, 58.3% were detected by both gastroscopy and MGCE at immediate assessment and review of recorded data. Capsule examination missed 14 findings and gastroscopy missed 31 findings seen with MGCE. Overall diagnostic yield was similar for both modalities. Pilot study. Diagnostic results were similar for the 2 methods. After some technical difficulties related to gastric expansion or presence of mucus had been overcome, this study opened a new field for noninvasive gastric examination in countries where high gastric cancer incidence demands a screening tool.

Self-expandable metal stents (SEMSs) can be used for the palliation of malignant obstruction in the upper gastrointestinal tract. This study assessed the feasibility and efficacy of endoscopically inserted SEMSs for the palliation of malignant obstruction in the stomach and duodenum. Between January 2011 and April 2014, 220 patients with gastric or duodenal obstruction due to malignancy underwent endoscopic SEMS insertion at Asan Medical Center. The associations of technical/clinical outcomes and complications with the type of stent and site of obstruction were analyzed. The 220 patients included 125 men (56.8 %) and 95 women (43.2 %); median patient age was 63 years. Fully covered, partially covered, and uncovered SEMSs were inserted into 16, 77, and 120 patients, respectively. Obstructions were located in the gastric outlet, including the duodenal bulb, in 106 patients, and in the duodenal second and third portions in 114 patients. Technical success was achieved in 213 of 220 patients (96.8 %) and clinical success in 184 of 213 (86.4 %). Clinical success rates were similar to the type of stent, but were significantly greater for gastric outlet (95/104, 91.3 %) than for duodenal (89/109, 81.7 %) obstructions (p = 0.039). Stent migration was observed in 20 patients (9.1 %) and stent obstruction in 51 (23.2 %). Rates of stent migration were significantly higher for fully covered (6/16, 37.5 %) than for partially covered (7/77, 9.1 %) and uncovered (7/120, 5.8 %) SEMSs (p < 0.001) and were significantly higher for gastric outlet (16/104, 15.4 %) than for duodenal (4/109, 1.2 %) obstructions (p = 0.003). Rates of stent obstruction were similar for fully covered (2/16, 12.5 %), partially covered (17/77, 22.1 %), and uncovered (32/120, 26.7 %) SEMSs (p = 0.409) and in patients with gastric outlet (26/104, 25.0 %) and duodenal (25/109, 22.9 %) obstruction (p = 0.724). SEMS selection for malignant obstruction of the upper gastrointestinal tract depends on the site of obstruction.

Bevacizumab improves survival in several solid tumor malignancies when combined with chemotherapy. We evaluated the efficacy and safety of the addition of bevacizumab to chemotherapy in the treatment of gastric and gastroesophageal junction (GEJ) adenocarcinoma. Forty-seven patients with metastatic or unresectable gastric/GEJ adenocarcinoma were treated with bevacizumab 15 mg/kg on day 1, irinotecan 65 mg/m2, and cisplatin 30 mg/m2 on days 1 and 8, every 21 days. The primary end point was to demonstrate a 50% improvement in time to progression over historical values. Secondary end points included safety, response, and survival. Patient characteristics were as follows: median age 59 years (range, 25 to 75); Karnofsky performance status 90% (70% to 100%); male:female, 34:13; and gastric/GEJ, 24:23. With a median follow-up of 12.2 months, median time to progression was 8.3 months (95% CI, 5.5 to 9.9 months). In 34 patients with measurable disease, the overall response rate was 65% (95% CI, 46% to 80%). Median survival was 12.3 months (95% CI, 11.3 to 17.2 months). We observed no increase in chemotherapy related toxicity. Possible bevacizumab-related toxicity included a 28% incidence of grade 3 hypertension, two patients with a gastric perforation and one patient with a near perforation (6%), and one patient with a myocardial infarction (2%). Grade 3 to 4 thromboembolic events occurred in 25% of patients. Although the primary tumor was unresected in 40 patients, we observed only one patient with a significant upper gastrointestinal bleed. Bevacizumab can be safely given with chemotherapy even with primary gastric and GEJ tumors in place. The response rate, time to disease progression (TTP), and overall survival are encouraging, with TTP improved over historical controls by 75%. Further development of bevacizumab in gastric and GEJ cancers is warranted.

Considering the poor prognosis of patients with gastric cancer, molecular diagnostic and prognostic markers for this cancer should be established. The aims of our study were to assess the correlations between PTEN, HER2/neu, and Ki67 expressions and clinicopathological factors of gastric cancer patients in upper Egypt, as well as their influence on OS and DFS. In this descriptive-analytic study, 42 patients with gastric carcinoma treated by postioerative chemoradiation between 2004 and 2014. Pathological review was done. Immunohistochemical staining and evaluation were performed. All the studied markers were significantly correlated with increased TNM stage. Her2/neu overexpression and positive Ki67 expression were significantly associated with histological grade. High percentage of positive Her2/neu and Ki67expression was found in gastric carcinoma tissue samples which lack PTEN expression. The one-year OS rate for the entire group (n=42) was 77.4%, whereas the DFS rate was 45%. Pathological T stage PTEN status significantly affected both OS (p=0.029 and 0.027 respectively) and DFS (p=0.006 and 0.012 respectively) rates. Multivariate Cox analyses showed that only pathological T stage was an independent prognostic factor affecting OS (P=0. 007, HR: 2.02; 95% CI: 1.2-3.38)and DFS(P<0.0001, HR: 2.69; 95% CI: 1.54-4.69). All the studied molecular markers, was significantly correlated with pathological T stage that significantly affected both OS and DFS rates. These findings indicate that these markers have an important role in gastric cancer growth and dissemination so these markers can be used as a prognostic biomarker. In addition, therapies targeting Her2 and PTEN may help develop novel therapeutics for gastric cancer. Copyright © 2017 Elsevier B.V. All rights reserved.

The purpose of our investigative work has been to determine whether there can be therapeutic roles in the administration of sildenafil citrate, heparin and several neuropeptides on an animal model where gastric ulcers were induced with acetic acid, and to compare their efficacy. The animals were divided into 13 groups, with 4 animals in each. Gastric ulcers was induced in the animals of 12 groups with one untreated group being left as the control (Group I - control; given normal saline (NS)). The other groups were: Group II (ulcer+NS); Group III (5mg/kg sildenafil citrate, low dose); Group IV (10mg/kg sildenafil citrate, high dose); Group V (0.6mg/kg heparin, low dose); Group VI (6mg/kg heparin, high dose); Group VII (20nmol/kg des-acyl ghrelin); Group VIII (40nmol/kg des-acyl ghrelin); Group IX (4nmol/kg acyl ghrelin); Group X (8nmol/kg acly ghrelin); Group XI (20pmol/kg Nesfatin-1); Group XII (15nmol/kg Obestatin) and Group XIII (5nmol/kg Neuropeptide Y). Gastric neuropeptide expression was measured using an immunohistochemical method, and the amount in circulation was detected using ELISA. To compare with no treatment, the controls and other treatment groups, we recorded loss of the surface epithelium of the stomach, erosion, bleeding and inflammatory cell infiltration in the upper halves of the gastric glands. The muscularis and the layers beneath it were, however, apparently normal. The gastric mucosa healed with little or no inflammation when sildenafil citrate, low dose heparin, ghrelin, NUCB2/Nesfatin-1, obestatin, Neuropeptide Y were administered. Overall the data indicate that low dose heparin, and especially sildenafil citrate and neuropeptides, can be used clinically as an alternative approach in the treatment of the gastric ulcer.

A 43-year-old female patient presented with a chief complaint of upper abdominal pain. As her complaints had lasted for 1 month, an upper gastrointestinal system endoscopy was performed and discovered a bezoar in the stomach. The bezoar was quite hard and light green-yellow in color. Pathological examination revealed phytobezoar. The patient was hospitalized and given oral Coca-Cola(®) Zero for seven days at a dose of 500 mL three times daily. The upper gastrointestinal system endoscopy performed at the end of 7 days showed that the phytobezoar had softened and become smaller. The phytobezoar was broken into pieces with biopsy forceps and washing was applied, so the phytobezoar pieces could pass through the pylorus. The patient was discharged after the procedure without problem.

Autoimmune gastritis is often suspected for its hematologic findings, and rarely the diagnosis is made for the presence of gastrointestinal symptoms. Aims of this cross-sectional study were to assess in a large cohort of patients affected by autoimmune gastritis the occurrence and the pattern of gastrointestinal symptoms and to evaluate whether symptomatic patients are characterized by specific clinical features.Gastrointestinal symptoms of 379 consecutive autoimmune gastritis patients were systematically assessed and classified following Rome III Criteria. Association between symptoms and anemia pattern, positivity to gastric autoantibodies, Helicobacter pylori infection, and concomitant autoimmune disease were evaluated.In total, 70.2% of patients were female, median age 55 years (range 17-83). Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present. However, 56.7% of patients complained of gastrointestinal symptoms, 69.8% of them had exclusively upper symptoms, 15.8% only lower and 14.4% concomitant upper and lower symptoms. Dyspepsia, subtype postprandial distress syndrome was the most represented, being present in 60.2% of symptomatic patients. Univariate and multivariate analyses showed that age <55 years (OR 1.6 [CI:1-2.5]), absence of smoking habit (OR 2.2 [CI:1.2-4]), and absence of anemia (OR 3.1 [CI:1.5-6.4]) were independent factors associated to dyspepsia.Autoimmune gastritis is associated in almost 60% of cases with gastrointestinal symptoms, in particular dyspepsia. Dyspepsia is strictly related to younger age, no smoking, and absence of anemia.

Sleeve gastrectomy is increasingly used in the treatment of morbid obesity, but its long-term outcome vs the standard Roux-en-Y gastric bypass procedure is unknown. To determine whether there are differences between sleeve gastrectomy and Roux-en-Y gastric bypass in terms of weight loss, changes in comorbidities, increase in quality of life, and adverse events. The Swiss Multicenter Bypass or Sleeve Study (SM-BOSS), a 2-group randomized trial, was conducted from January 2007 until November 2011 (last follow-up in March 2017). Of 3971 morbidly obese patients evaluated for bariatric surgery at 4 Swiss bariatric centers, 217 patients were enrolled and randomly assigned to sleeve gastrectomy or Roux-en-Y gastric bypass with a 5-year follow-up period. Patients were randomly assigned to undergo laparoscopic sleeve gastrectomy (n = 107) or laparoscopic Roux-en-Y gastric bypass (n = 110). The primary end point was weight loss, expressed as percentage excess body mass index (BMI) loss. Exploratory end points were changes in comorbidities and adverse events. Among the 217 patients (mean age, 45.5 years; 72% women; mean BMI, 43.9) 205 (94.5%) completed the trial. Excess BMI loss was not significantly different at 5 years: for sleeve gastrectomy, 61.1%, vs Roux-en-Y gastric bypass, 68.3% (absolute difference, -7.18%; 95% CI, -14.30% to -0.06%; P = .22 after adjustment for multiple comparisons). Gastric reflux remission was observed more frequently after Roux-en-Y gastric bypass (60.4%) than after sleeve gastrectomy (25.0%). Gastric reflux worsened (more symptoms or increase in therapy) more often after sleeve gastrectomy (31.8%) than after Roux-en-Y gastric bypass (6.3%). The number of patients with reoperations or interventions was 16/101 (15.8%) after sleeve gastrectomy and 23/104 (22.1%) after Roux-en-Y gastric bypass. Among patients with morbid obesity, there was no significant difference in excess BMI loss between laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass at 5 years of follow-up after surgery. clinicaltrials.gov Identifier: NCT00356213.

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.

'Marjoram,' Origanum majorana L., a culinary aromatic medicinal herb is known to possess various therapeutic properties. We evaluated the antiulcerogenic activity of the ethanol extract in hypothermic restraint stress-, indomethacin-, necrotizing agents- (80% ethanol, 25% NaCl and 0.2 M NaOH) induced ulcers and basal gastric acid secretion using pylorus ligated Shay rat-model. Marjoram at doses of 250 and 500 mg/kg of body weight, significantly decreased the incidence of ulcers, basal gastric secretion and acid output. Furthermore, the extract replenished the ethanol-induced depleted gastric wall mucus and nonprotein sulfhydryls (NP-SH) contents and significantly lowered the increase in the concentration of malondialdehyde (MDA). Ulcer preventing potential was further confirmed by histopathological assessment. An acute toxicity test showed a large margin of safety of the extract in mice. The phytochemical screening of aerial parts of marjoram revealed the presence of volatile oil, flavonoids, tannins, sterols and/or triterpenes.

Wittmers, L.E. Jr.; Anderson, L.A.; Fall, M.M.

In an attempt to find a method of gastric mucosal damage assessment that yields consistent results, the experiments presented here employed the measurement of the movement of inulin out of the gastric contents into the stomach wall and vascular compartment as an estimate of mucosal damage. Anesthetized male Sprague-Dawley rats were functionally nephrectomized and were administered a control or test solution containing 3H-inulin. The test solutions contained one of three doses of aspirin. Blood samples were taken at 15-min intervals over a 90-min exposure period. The stomach was removed from the animal and full-thickness tissue samples taken for measurement ofmore » 3H-inulin content. When the gastric mucosa was exposed to the test agents, there was a significantly greater accumulation of inulin in the body and antrum as well as in the plasma when compared to controls. We conclude that intragastric inulin can be employed to estimate gastric mucosal damage.« less

Bariatric surgery using laparoscopic techniques is the most effective treatment for morbid obesity. The objective of the study is to assess the safety and efficacy of a novel laparoscopic reversible gastric restrictive (RGR) device in a group of obese dogs. An implant was also performed in a cadaver to assess implant feasibility in a human. Four obese mongrel dogs were subjected to RGR implantation for 3 months followed by recovery for an additional 6 weeks after device removal. Food intake, body weight, radiographic barium imaging, and gastric endoscopy were used to monitor RGR performance before implant, after implant, and implant removal. An additional RGR laparoscopic implantation procedure was performed in a human cadaver. The implanted obese dogs exhibited a significant decrease in food intake and body weight over 3 months with the RGR device. The reduction of food intake was sustained at an average of 46 % after implant and the excess weight loss reached an average of 75 % at the end of 12 weeks with recovery to approximately 78 % of baseline after 6 weeks of implant removal. Barium imaging and gastric endoscopy both confirmed passage for food through the restrictive device channel in the stomach. The RGR device was successfully implanted laparoscopically on the cadaver stomach in less than an hour. The RGR device is laparoscopically deliverable and removable with effective and sustainable weight loss over a 12-week period in an obese dog model. The implant is also technically feasible in man.

There are many available drugs for treating gastric ulcer, but they have various side effects. Ginger is a folk, herbal medicine, which is used for treatment of various diseases including gastric ulcer. This study investigates the possible mechanism of the protective effect of ginger on aspirin induced gastric ulcer. Forty adult male albino rats were randomized into four groups (10 animal per each group) and orally received the followings once daily for 5 days: Group I: 3 ml of 1% carboxymethyl cellulose; Group II: ginger powder (200 mg/kg body weight) suspended in 3 mL of 1% carboxymethylcellulose; Group III: aspirin (400 mg/kg body weight) suspended in 3 ml of 1% carboxymethylcellulose in water. Group IV: ginger and 30 minutes later, received aspirin suspended in 1% carboxymethylcellulose, in similar doses as received in groups II and III. On day 6, rats were sacrificed. The animals were anesthetized and the stomach was removed for the macroscopic, histological (Haematoxylin & Eosin and Periodic Acid Shiff) and immunohistochemical investigations (Bax, inducible nitric oxide synthase and heat shock protein 70). Aspirin induced a significant increase of the macroscopic ulcer score, shed and disrupted epithelium, mucosal hemorrhage, submucosal edema and leukocyte infiltration, loss of the mucus of the mucosal surface significantly increased expression of apoptosis regulator Bax, inducible nitric oxide synthase (iNOS) and heat shock protein 70 (HSP70). Ginger ameliorated the histological changes by reducing Bax and iNOS and increasing HSP70 expressions.

Our objective was to evaluate the long-term results of laparoscopic Roux-en-Y gastric bypass on excess weight loss, remission of the metabolic syndrome, and complications in Indian patients with uncontrolled type 2 diabetes mellitus (T2DM) with a body mass index of 30-35 kg/m(2). The setting was a corporate hospital in Mumbai, India. The present prospective observational study was begun in January 2006. A total of 52 patients with uncontrolled T2DM and a body mass index of 30-35 kg/m(2) elected to undergo laparoscopic Roux-en-Y gastric bypass. The duration of T2DM was 3.5-14.5 years (median 8.4). Of the 52 patients, 61.5% had hypertension and 59.6% had dyslipidemia. Remission of T2DM and other components of the metabolic syndrome were assessed. All patients were followed up for 5 years. The median percentage of excess weight loss was 72.2% at 1 year and 67.8% at 5 years. Of the 52 patients, 84.6% had achieved euglycemia and 73.1% had achieved complete remission, 23.1% partial remission, and 3.84% no remission at 1 year. Weight regain occurred in 8 patients. They required antihypertensive drugs and statins, decreasing the complete remission rate to 57.7% and partial remission rate to 38.5% at 5 years. However, 96.2% improvement in metabolic status was found at the end of 5 years. Laparoscopic Roux-en-Y gastric bypass is a safe, efficacious, and cost-effective treatment for uncontrolled T2DM in patients with a body mass index of 30-35 kg/m(2). Early-onset T2DM, better weight loss, and greater C-peptide levels were predictors of success after surgery. The improvement after surgery in hyperglycemia, hypertension, and dyslipidemia could help in controlling the occurrence of micro- and macrovascular complications and decrease the morbidity and mortality associated with T2DM.

The Ballistic Six exercise program includes commonly used upper-body exercises, and the program is recommended for overhead throwing athletes. The purpose of the current study was to investigate the effects of a 12-week the Ballistic Six upper-extremity plyometric training program on upper-body explosive power, endurance, and reaction time in pediatric overhead athletes. Twenty-eight female pediatric volleyball players participated in the study. The participants were randomly divided into 2 study groups: an intervention group (upper-extremity plyometric training in addition to the volleyball training; n = 14) and a control group (the volleyball training only; n = 14). All the participants were assessed before and after a 12-week training program for upper-body power, strength and endurance, and reaction time. Statistical comparison was performed using an analysis of variance test. Comparisons showed that after a 12-week training program, the Ballistic Six upper-body plyometric training program resulted in more improvements in an overhead medicine ball throwing distance and a push-up performance, as well as greater improvements in the reaction time in the nonthrowing arm when compared with control training. In addition, a 12-week training program was found to be effective in achieving improvements in the reaction time in the throwing arm for both groups similarly. Compared with regular training, upper-body plyometric training resulted in additional improvements in upper-body power and strength and endurance among pediatric volleyball players. The findings of the study provide a basis for developing training protocols for pediatric volleyball players.
