METHODS Seventy-five gastric antral biopsy speci- mens from the patients examined by six other methods for Hp were fixed in glutaraldehyde and treated with tanin acid before OsO_4 staining than routinely prooessed for TEM studies (at least 4 semi- thin sections oriented for ultrathin sections in each sample). RESULTS The bacilli were detected by TEM within gastric mucosa in 53 of 55 patients infected with Hp. Ultrathin sections especially stained with tanin acid re- vealed clearly glycocalyx by which the bacillus was connected with the epithelium. As the bacilli grouped as colony and breed,the adjacent mucous cells degerated and characterized by erosion of the juxtalu- minal cytoplasm,vacuolation or blebs,even desqua- mation of cell. Evidence was accumulated to show that the baoilli were located in the lumen attracted neu- trophils which intended to migrate into intercellular space of epithelia or into the lumen to exert the effect of Hp phagocytosis. CONCLUSIONS The sensitivity and specificity of Hp diagnosis by TEM is respectively 96% and 95%. Tanin acid is suitable for the preservation of glycocalyx of cell. The colonized bacilli,usually with the wide periplasmic pools,contributed to the spectrum degen- eration of epithelia,including mucous neck cells. If Hp infection persists,the degeneration and regeneration of mucous neck cells alternatively carried on and ultimate- ly the generative stem cells were damaged,as the result,the chronic atrophy gastritis could occure.展开更多

Polymorphisms of these cytokine genes are associated with individual differences in gastric mucosal cytokine mRNA level, which result in differences in gastric mucosal inflammation, acid inhibition and gastroduodenal disease risk in response to H. pylori infection. Although polymorphisms of interleukin (IL)-1B, IL-1RN and TNF-A have been reported to relate well with gastric cancer and peptic ulcer risk, those of IL-2, IL-4, IL-6 and IL-8 genes are unclear. In combined analyses using data from previous studies, we found that the risk of gastric non-cardia cancer development was significantly associated with IL-4-168 C allele (OR: 0.81, 95% CI: 0.69-1.00) and IL-4-590 T allele carrier status (0.61, 0.53-0.73), and IL-6-174 G/G genotype (2<Abstract>Pro-inflammatory cytokines are produced in the gastric mucosa by inflammatory cells activated by chronic Helicobacter pylori (H. pylori) infection.

Acute toxicity of the essential oil was assessed in animal model. In vitro anti-Helicobacter pylori activity was performed through disc diffusion and minimum inhibitory concentration method. For gastroprotective assay, rats received Pistacia atlantica Desf. essential oil(25, 50 and 100 mg/kg orally) 1 h before induction of ulcer by ethanol.Macroscopic(ulcer index and protection rate) and microscopic examination were performed.RESULTS: The GC/MS analysis of the essential oil led to the identification of twenty constituents andα-pinene is predominant constituent. The essential oil was safe up to 2000 mg/kg. All Helicobacter pylori strains were susceptible to the essential oil and the MIC ranged from 275 to 1100 μg/m L. The ulcer index for treated groups was significantly reduced compared to control(P < 0.001) with EC50 value of 12.32 mg/kg. In microscopic examination, Pistacia atlantica attenuated destruction and necrosis of gastric tissue.CONCLUSION: Current study exhibited protective effect of standardized Pistacia atlantica essential oil against ethanol-induced gastric ulcer and its antibacterial activity on Helicobacter pylori. α-pinene might be the responsible agent.展开更多

METHODS： This prospective, randomized, comparative trial was conducted in a medical center. A total of 228 patients with actively bleeding ulcers （spurting or oozing） were randomly assigned to three groups with 20, 30 and 40 mL endoscopic injections of an 1：10000 solution of epinephrine. The hemostatic effects and clinical outcomes were compared between the three groups. RESULTS： There were no significant differences in all background variables between the three groups. Initial hemostasis was achieved in 97.4%, 98.7% and 100% of patients respectively in the 20, 30 and 40 mL epinephrine groups. There were no significant differences in the rate of initial hemostasis between the three groups. The rate of peptic ulcer perforation was significantly higher in the 40 mL epinephrine group than in the 20 and 30 mL epinephrine groups （P 〈 0.05）. The rate of recurrent bleeding was significantly higher in the 20 mL epinephrine group （20.3%） than in the 30 （5.3%） and 40 mL （2.8 %） epinephrine groups （P 〈 0.01）. There were no significant differences in the rates of surgical intervention, the amount of transfusion requirements, the days of hospitalization, the deaths from bleeding and 30 d mortality between the three groups. The number of patients who developed epigastric pain due to endoscopic injection, was significantly higher in the 40 mL epinephrine group （51/76） than in the 20 （2/76） and 30 mL （5/76） epinephrine groups （P 〈 0.001）. Significant elevation of systolic blood pressure after endoscopic injection was observed in the 40 mL epinephrine group （P 〈 0.01）. Significant decreasing and normalization of pulse rates after endoscopic injections were observed in the 20 mL and 30 mL epinephrine groups （P 〈 0.01）.CONCLUSION： Injection of 30 mL diluted epinephrine （1：10000） can effectively prevent recurrent bleeding with a low rate of complications. The optimal injection volume of epinephrine for endoscopic treatment of an actively bleeding ulcer （spurting or oozing） is 30 mL.展开更多

METHODS: We enrolled 348 adult patients (62 gastric adenocarcinoma, 45 PUD and 241 NUD) undergoing upper gastrointestinal endoscopy at two referral centers between September, 2002 and May, 2007. H pylori infection was diagnosed when any of the four tests (RUT, culture, histopathology and PCR) were positive. Genotyping for -765G > C polymorphism of COX-2 was performed by PCR-RFLP analysis. RESULTS: Frequency of C carrier had significantassociation with gastric adenocarcinoma as compared to NUD [77.4% vs 29%, P < 0.001, odds ratio (OR) 8.20; 95% confidence interval (95% CI), 4.08-16.47] and PUD (77.4% vs 31.1%, P < 0.001; OR 8.04; 95% CI, 3.25-19.90). Risk of gastric adenocarcinoma was significantly higher in patients having C carrier with (OR 7.83; 95% CI 3.09-19.85) and without H pylori infection (OR 7.06; 95% CI, 2.61-19.09). Patients with C carrier and H pylori infection had significant risk for the development of PUD (P < 0.001; OR 5.65; 95% CI, 2.07-15.34). CONCLUSION: -765G > C COX-2 polymorphism with or without H pylori could be a marker for genetic susceptibility to gastric adenocarcinoma. COX-2 polymorphism in presence of H pylori infection might be useful in predicting the risk of PUD.展开更多

The incidence of PUD has been estimated at around 1.5% to 3%. Perforated peptic ulcer(PPU) is a serious complication of PUD and patients with PPU often present with acute abdomen that carries high risk for morbidity and mortality. The lifetime prevalence of perforation in patients with PUD is about 5%. PPU carries a mortality ranging from 1.3% to 20%. Thirtyday mortality rate reaching 20% and 90-d mortality rate of up to 30% have been reported. In this review we have summarized the current evidence on PPU to update readers. This literature review includes the most updated information such as common causes, clinical features, diagnostic methods, non-operative and operative management, post-operative complications and different scoring systems of PPU. With the advancement of medical technology, PUD can now be treated with medications instead of elective surgery. The classic triad of sudden onset of abdominal pain, tachycardia and abdominal rigidity is the hallmark of PPU. Erect chest radiograph may miss 15% of cases with air under the diaphragm in patients with bowel perforation. Early diagnosis, prompt resuscitation and urgent surgical intervention are essential to improve outcomes. Exploratory laparotomy and omental patch repair remains the gold standard. Laparoscopic surgery should be considered when expertise is available. Gastrectomy is recommended in patients with large or malignant ulcer.展开更多

METHODS: A total of 4471 patients (48.3% female) out of 4863 attended the Samatya hospital in Istanbul (June 1999 - October 2003) were included. The records of H pylori status (CLO-test), endoscopic f indings of GU, DU and gastritis, personal habits (smoking, alcohol intake) and medication [non-steroidal anti-inflammatory drugs (NSAIDs), aspirin intake] were analyzed using multi-way frequency analysis. RESULTS: We have found that GU in the presence of H pylori had significant association with aspirin (P = 0.0001), alcohol (P = 0.0090) and NSAIDs (P = 0.0372). DU on the other hand had significant association with aspirin/ smoking/NSAIDs (P = 0.0259), aspirin/alcohol (P = 0.0002) and aspirin/smoking (P = 0.0233), also in the presence of H pylori. In the absence of H pylori GU had significant association with alcohol/NSAIDs (P = 0.0431), and NSAIDs (P = 0.0436). While DU in the absence of H pylori had significant association with smoking/alcohol/ NSAIDs (P = 0.0013), aspirin/NSAIDs (P = 0.0334), aspirin/alcohol (P = 0.0360). CONCLUSION: In the presence of H pylori, aspirin, alcohol and NSAIDs intake act as an independent risk factors that had an augmenting impact on the occurrence of GU and only together on the occurrence of DU in Turkish patients.展开更多

One hundred and fourteen patients had non-ulcer dyspepsia and 66 had peptic ulcer disease (32 with gastric ulcers and/or erosions and 34with duodenal ulcers). Each patient was tested for serum antibody to H. pylori cagA protein by enzyme immunoassay.RESULTS: The total frequency of serum positive cagA in the study group was 97.2 %. The rates in the patients with peptic ulcers and in those with non-ulcer dyspepsia were 100% and 95.6%, respectively. These results were similar to those reported in Asian studies, but higher than those that have been noted in other studies from Turkey and Western countries.CONCLUSION: The high rates of serum positive cagA in these patients with peptic ulcer disease and non-ulcer dyspepsia were similar to results reported in Asia. The fact that there was high seroum prevalence regardless of ulcer status suggests that factors other than cagA might be responsible for ulceration or other types of severe pathology in H. pylori-positive individuals.展开更多

METHODS:A multicenter prospective cohort study was conducted between November 2000 and December 2007 in Yamagata Prefecture,Japan.The study included patients with H pylori-positive peptic ulcer who decided themselves whether to receive H pylori eradication(eradication group)or conventional antacid therapy(non-eradication group).Incidence of gastric cancer in the two groups was determined based on the results of annual endoscopy and questionnaire surveys,as well as Yamagata Prefectural Cancer Registry data,and was compared between the two groups and by results of H pylori therapy.RESULTS:A total of 4133 patients aged between 13 and 91 years(mean 52.9 years)were registered,and 56 cases of gastric cancer were identified over a mean follow-up of 5.6 years.The sex-and age-adjusted incidence ratio of gastric cancer in the eradication group, as compared with the non-eradication group,was 0.58 (95%CI:0.28-1.19)and ratios by follow-up period(<1 year,1-3 years,>3 years)were 1.16(0.27-5.00),0.50 (0.17-1.49),and 0.34(0.09-1.28),respectively.Longer follow-up tended to be associated with better prevention of gastric cancer,although not to a significant extent.No significant difference in incidence of gastric cancer was observed between patients with successful eradication therapy(32/2451 patients,1.31%)and those with treatment failure(11/639 patients,1.72%).Among patients with duodenal ulcer,which is known to be more prevalent in younger individuals,the incidence of gastric cancer was significantly less in those with successful eradication therapy(2/845 patients,0.24%)than in those with treatment failure(3/216 patients,1.39%). CONCLUSION:H pylori eradication therapy for peptic ulcer patients with a mean age of 52.9 years at registration did not significantly decrease the incidence of gastric cancer.展开更多

The endoscopic findings were classified according to the Lanza score, and the scores were compared between groups categorized according to the concomitant use of anti-ulcer drugs and the types of drugs used. In another study, 31 hemorrhagic peptic ulcer patients who had been receiving low-dose aspirin were enrolled. The patients were randomly classified into the proton pump inhibitor （PPI）-treated group and the H2 receptor antagonist （H2RA）-treated group. The administration of low-dose aspirin was continued concomitantly, and endoscopic examinations were performed 8 wk later.RESULTS： The Lanza scores （mean ± SD） of the gastro-mucosal lesions were 1.0 ± 1.9 and 1.9 ± 2.3 in 8 and 16 patients receiving prevention therapy with a PPI and an H2RA, respectively. Both scores were significantly smaller than the scores in 34 patients who were not receiving prevention therapy （4.7 ± 1.0） and in 10 patients receiving cytoprotective anti-ulcer drugs （4.3± 1.6）. In the prospective study, 18 and 13 patients received a PPI and an H2RA, respectively. Endoscopic examinations revealed that the tissue in the region of the gastro-mucosal lesions had reverted to normal in all patients in the PPI-treated group and in 12 patients （92%） in the H2RA-treated group; no significant differences were observed between the groups.CONCLUSION： H2RA therapy was effective for both the prevention and treatment of low-dose aspirin-induced peptic ulcer, similar to the effects of PPIs, while cytoprotective anti-ulcer drugs were ineffective in preventing ulceration.展开更多

METHODS All clinical data of peptic ulcer patients treated from January 1, 2009 to January 1, 2014 were retrospectively collected and analyzed. Patients were divided into either a continuing group to continue taking antithrombotic drugs after ulcer bleeding or a discontinuing group to discontinue antithrombotic drugs. The primary outcome of follow-up in peptic ulcer bleeding patients was recurrent bleeding, and secondary outcome was death or acute cardiovascular disease occurrence. The final date of follow-up was December 31, 2014. Basic demographic data, complications, and disease classifications were analyzed and compared by t- or χ2-test. The number of patients that achieved various outcomes was counted and analyzed statistically. A survival curve was drawn using the Kaplan-Meier method, and the differencewas compared using the log-rank test. COX regression multivariate analysis was applied to analyze risk factors for the prognosis of peptic ulcer patients. RESULTS A total of 167 patients were enrolled into this study. As for the baseline information, differences in age, smoking, alcohol abuse, and acute cardiovascular diseases were statistically significant between the continuing and discontinuing groups(70.8 ± 11.4 vs 62.4 ± 12.0, P < 0.001; 8(8.2%) vs 15(21.7%), P < 0.05; 65(66.3%) vs 13(18.8%), P < 0.001). At the end of the study, 18 patients had recurrent bleeding and three patients died or had acute cardiovascular disease in the continuing group, while four patients had recurrent bleeding and 15 patients died or had acute cardiovascular disease in the discontinuing group. The differences in these results were statistically significant(P = 0.022, P = 0.000). The Kaplan-Meier survival curve indicated that the incidence of recurrent bleeding was higher in patients in the continuing group, and the risk of death and developing acute cardiovascular disease was higher in patients in the discontinuing group(log-rank test, P = 0.000 for both). Furthermore, COX regression multivariate analysis revealed that the hazard ratio(HR) for recurrent bleeding was 2.986(95%CI: 067-8.356, P = 0.015) in the continuing group, while HR for death or acute cardiovascular disease was 5.216(95%CI: 1.035-26.278, P = 0.028).CONCLUSION After the occurrence of peptic ulcer bleeding, continuing antithrombotics increases the risk of recurrent bleeding events, while discontinuing antithrombotics would increase the risk of death and developing cardiovascular disease. This suggests that clinicians should comprehensively consider the use of antithrombotics after peptic ulcer bleeding.展开更多

文摘Peptic ulcer(PU)is characterized by inflammation,necrosis,and erosion of the gastrointestinal mucosa caused by various pathogenic factors,leading to ulcer formation.The stomach and duodenum are the most commonly affected sites.Bletilla striata,a traditional Chinese medicinal herb,contains diverse chemical constituents and exhibits multiple pharmacological effects.As a key component in various traditional Chinese medicine compound formulations,it has demonstrated notable clinical efficacy.Moreover,it has a solid research foundation and broad application prospects in the treatment of gastrointestinal diseases.This paper systematically elaborates on the clinical efficacy and mechanisms of action of Bletilla striata in the treatment of PUs,drawing from ancient medical literature and traditional formula applications to provide support for clinical use.
文摘BACKGROUND The use of proton pump inhibitors(PPIs)with the intent of reducing gastric acidity to the desired therapeutic level for treating bleeding peptic ulcer still has several limitations.AIM To compare intravenous PPIs and oral potassium competitive acid blockers(PCABs)administered prior to endoscopic treatment of bleeding peptic ulcers.METHODS This retrospective study involved 105 consecutive patients with non-variceal upper gastrointestinal bleeding(treated August 2023 to February 2024).Prior to emergency endoscopy,patients received either intravenous PPI(pantoprazole 80 mg bolus)or oral PCAB(tegoprazan 50 mg single-dose).Severity of bleeding was assessed using the Glasgow-Blatchford,Rockall,and AIMS65 scoring systems.Patients with severe comorbidities were excluded.Primary outcomes included need for therapeutic endoscopic intervention and occurrence of re-bleeding.Multivariate logistic regression was performed to adjust for potential confounding factors.RESULTS Total of the 105 patients,61 received intravenous PPI injection and 44 received oral PCAB prior to emergency endoscopy.To minimize selection bias,bleeding severity was assessed using the Glasgow-Blatchford,Rockall and AIMS65 scores,with no statistically significant differences observed between the two groups.During emergency endoscopy performed within 48 hours,ulcer bed status was classified according to the Forrest classification.The proportion of lesions graded IIa or higher was significantly lower in the PCAB group(P<0.001),as was the frequency of therapeutic endoscopy intervention(odds ratio=0.272,95%confidence interval:0.111-0.665,P=0.004).The frequency of re-bleeding events was statistically significantly higher in the PPI group(odds ratio=0.141,95%confidence interval:0.024-0.844,P=0.032).CONCLUSION Pre-endoscopic PCAB administration is more effective than PPI injection for upper gastrointestinal bleeding and may reduce ulcer bleeding mortality.
文摘BACKGROUND Nonoperative management(NOM)is a promising therapeutic modality for patients with perforated peptic ulcer(PPU).However,the risk factors for poor efficacy and adverse events of NOM are a concern.AIM To investigate the factors predictive of poor efficacy and adverse events in patients with PPU treated by NOM.METHODS This retrospective case-control study enrolled 272 patients who were diagnosed with PPU and initially managed nonoperatively from January 2014 to December 2018.Of these 272 patients,50 converted to emergency surgery due to a lack of improvement(surgical group)and 222 patients were included in the NOM group.The clinical data of these patients were collected.Baseline patient characteristics and adverse outcomes were compared between the two groups.Logistic regression analysis and receiver operating characteristic curve analyses were conducted to investigate the factors predictive of poor efficacy of NOM and adverse outcomes in patients with PPU.RESULTS Adverse outcomes were observed in 71 patients(32.0%).Multivariate analyses revealed that low serum albumin level was an independent predictor for poor efficacy of NOM and adverse outcomes in patients with PPU.CONCLUSION Low serum albumin level may be used as an indicator to help predict the poor efficacy of NOM and adverse outcomes,and can be used for risk stratification in patients with PPU.

文摘AIMS The relationship between Helicobacter pylori (Hp) and gastric epithelia in chronic gastritis and in petic ulcer was studied by transmission electron mi- croscopy (TEM). METHODS Seventy-five gastric antral biopsy speci- mens from the patients examined by six other methods for Hp were fixed in glutaraldehyde and treated with tanin acid before OsO_4 staining than routinely prooessed for TEM studies (at least 4 semi- thin sections oriented for ultrathin sections in each sample). RESULTS The bacilli were detected by TEM within gastric mucosa in 53 of 55 patients infected with Hp. Ultrathin sections especially stained with tanin acid re- vealed clearly glycocalyx by which the bacillus was connected with the epithelium. As the bacilli grouped as colony and breed,the adjacent mucous cells degerated and characterized by erosion of the juxtalu- minal cytoplasm,vacuolation or blebs,even desqua- mation of cell. Evidence was accumulated to show that the baoilli were located in the lumen attracted neu- trophils which intended to migrate into intercellular space of epithelia or into the lumen to exert the effect of Hp phagocytosis. CONCLUSIONS The sensitivity and specificity of Hp diagnosis by TEM is respectively 96% and 95%. Tanin acid is suitable for the preservation of glycocalyx of cell. The colonized bacilli,usually with the wide periplasmic pools,contributed to the spectrum degen- eration of epithelia,including mucous neck cells. If Hp infection persists,the degeneration and regeneration of mucous neck cells alternatively carried on and ultimate- ly the generative stem cells were damaged,as the result,the chronic atrophy gastritis could occure.
文摘Pro-inflammatory cytokines are produced in the gastric mucosa by inflammatory cells activated by chronic Helicobacter pylori (H. pylori) infection. Polymorphisms of these cytokine genes are associated with individual differences in gastric mucosal cytokine mRNA level, which result in differences in gastric mucosal inflammation, acid inhibition and gastroduodenal disease risk in response to H. pylori infection. Although polymorphisms of interleukin (IL)-1B, IL-1RN and TNF-A have been reported to relate well with gastric cancer and peptic ulcer risk, those of IL-2, IL-4, IL-6 and IL-8 genes are unclear. In combined analyses using data from previous studies, we found that the risk of gastric non-cardia cancer development was significantly associated with IL-4-168 C allele (OR: 0.81, 95% CI: 0.69-1.00) and IL-4-590 T allele carrier status (0.61, 0.53-0.73), and IL-6-174 G/G genotype (2<Abstract>Pro-inflammatory cytokines are produced in the gastric mucosa by inflammatory cells activated by chronic Helicobacter pylori (H. pylori) infection.

文摘OBJECTIVE: To evaluate the efficacy of Pistacia atlantica Desf. oleoresin essential oil on peptic ulcer(PU) and its antibacterial effect on metronidazole-resistant Helicobacter pylori, as well as chemi-cal composition of the essential oil.METHODS: The essential oil was standardized using gas chromatography mass spectrometry(GC/MS) analysis. Acute toxicity of the essential oil was assessed in animal model. In vitro anti-Helicobacter pylori activity was performed through disc diffusion and minimum inhibitory concentration method. For gastroprotective assay, rats received Pistacia atlantica Desf. essential oil(25, 50 and 100 mg/kg orally) 1 h before induction of ulcer by ethanol.Macroscopic(ulcer index and protection rate) and microscopic examination were performed.RESULTS: The GC/MS analysis of the essential oil led to the identification of twenty constituents andα-pinene is predominant constituent. The essential oil was safe up to 2000 mg/kg. All Helicobacter pylori strains were susceptible to the essential oil and the MIC ranged from 275 to 1100 μg/m L. The ulcer index for treated groups was significantly reduced compared to control(P < 0.001) with EC50 value of 12.32 mg/kg. In microscopic examination, Pistacia atlantica attenuated destruction and necrosis of gastric tissue.CONCLUSION: Current study exhibited protective effect of standardized Pistacia atlantica essential oil against ethanol-induced gastric ulcer and its antibacterial activity on Helicobacter pylori. α-pinene might be the responsible agent.
文摘AIM:To assess the risk factors and the eff icacy of medications of patients with gastric and duodenal ulcers among Chinese patients in Taiwan.METHODS:Patients with peptic ulcers,diagnosed by upper endoscopy,were retrospectively collected between January 2008 and December 2008.The differences were compared.RESULTS:Among all 448 cases,254(56.6%) and 194(43.4%) patients had gastric ulcers and duodenal ulcers respectively.Patients with gastric ulcers were younger than those with duodenal ulcers.Although more men existed,there was a female predominance in middle-aged cases.Patients with duodenal ulcers had a higher rate of Helicobacter pylori(H.pylori) infection(62.4% vs 43.3%,P = 0.001),and those with gastric ulcers owned a significantly higher amount of aspirin and nonsteroidal anti-inflammatory drug(NSAID) use(7.5% vs 1.5%,6.7% vs 2.1%,P = 0.001).Tobacco smoking and alcohol drinking had no different impact between these two groups.Proton-pump inhibitors and H2-receptor antagonists(H2RA) were effective,but significantly less so in cases with duodenal ulcers receiving H2RAs,or in those with H.pylori infection and a history of NSAID use.CONCLUSION:Patients with gastric ulcers had lower H.pylori infection but more aspirin or NSAID use.Antisecretory therapy was ineffective in gastric ulcers underwent H2RA treatment,and cases combined H.pylori infection and NSAID use.
文摘AIM： To define the optimal injection volume of epinephrine with high efficacy for hemostasis and low complication rate in patients with actively bleeding ulcers. METHODS： This prospective, randomized, comparative trial was conducted in a medical center. A total of 228 patients with actively bleeding ulcers （spurting or oozing） were randomly assigned to three groups with 20, 30 and 40 mL endoscopic injections of an 1：10000 solution of epinephrine. The hemostatic effects and clinical outcomes were compared between the three groups. RESULTS： There were no significant differences in all background variables between the three groups. Initial hemostasis was achieved in 97.4%, 98.7% and 100% of patients respectively in the 20, 30 and 40 mL epinephrine groups. There were no significant differences in the rate of initial hemostasis between the three groups. The rate of peptic ulcer perforation was significantly higher in the 40 mL epinephrine group than in the 20 and 30 mL epinephrine groups （P 〈 0.05）. The rate of recurrent bleeding was significantly higher in the 20 mL epinephrine group （20.3%） than in the 30 （5.3%） and 40 mL （2.8 %） epinephrine groups （P 〈 0.01）. There were no significant differences in the rates of surgical intervention, the amount of transfusion requirements, the days of hospitalization, the deaths from bleeding and 30 d mortality between the three groups. The number of patients who developed epigastric pain due to endoscopic injection, was significantly higher in the 40 mL epinephrine group （51/76） than in the 20 （2/76） and 30 mL （5/76） epinephrine groups （P 〈 0.001）. Significant elevation of systolic blood pressure after endoscopic injection was observed in the 40 mL epinephrine group （P 〈 0.01）. Significant decreasing and normalization of pulse rates after endoscopic injections were observed in the 20 mL and 30 mL epinephrine groups （P 〈 0.01）.CONCLUSION： Injection of 30 mL diluted epinephrine （1：10000） can effectively prevent recurrent bleeding with a low rate of complications. The optimal injection volume of epinephrine for endoscopic treatment of an actively bleeding ulcer （spurting or oozing） is 30 mL.

文摘AIM: To investigate -765G > C COX-2 polymorphism and H pylori infection in patients with gastric adenocarcinoma, peptic ulcer disease (PUD) and non- ulcer dyspepsia (NUD). METHODS: We enrolled 348 adult patients (62 gastric adenocarcinoma, 45 PUD and 241 NUD) undergoing upper gastrointestinal endoscopy at two referral centers between September, 2002 and May, 2007. H pylori infection was diagnosed when any of the four tests (RUT, culture, histopathology and PCR) were positive. Genotyping for -765G > C polymorphism of COX-2 was performed by PCR-RFLP analysis. RESULTS: Frequency of C carrier had significantassociation with gastric adenocarcinoma as compared to NUD [77.4% vs 29%, P < 0.001, odds ratio (OR) 8.20; 95% confidence interval (95% CI), 4.08-16.47] and PUD (77.4% vs 31.1%, P < 0.001; OR 8.04; 95% CI, 3.25-19.90). Risk of gastric adenocarcinoma was significantly higher in patients having C carrier with (OR 7.83; 95% CI 3.09-19.85) and without H pylori infection (OR 7.06; 95% CI, 2.61-19.09). Patients with C carrier and H pylori infection had significant risk for the development of PUD (P < 0.001; OR 5.65; 95% CI, 2.07-15.34). CONCLUSION: -765G > C COX-2 polymorphism with or without H pylori could be a marker for genetic susceptibility to gastric adenocarcinoma. COX-2 polymorphism in presence of H pylori infection might be useful in predicting the risk of PUD.

文摘BACKGROUND The incidence of peptic ulcer disease has decreased during the last few decades,but the incidence of reported peptic ulcer complications has not decreased.Perforating peptic ulcer(PPU)is a severe form of the disease.AIM To assess trends in the incidence,presentation,and outcome of PPU over a period of 40 years.METHODS This was a single-centre,retrospective,cohort study of all patients admitted to Levanger Hospital,Norway,with PPU from 1978 to 2017.The patients were identified in the Patient Administrative System of the hospital using International Classification of Diseases(ICD),revision 8,ICD-9,and ICD-10 codes for perforated gastric and duodenal ulcers.We reviewed the medical records of the patients to retrieve data.Vital statistics were available for all patients.The incidence of PPU was analysed using Poisson regression with perforated ulcer as the dependent variable,and sex,age,and calendar year from 1978 to 2017 as covariates.Relative survival analysis was performed to compare long-term survival over the four decades.RESULTS Two hundred and nine patients were evaluated,including 113(54%)men.Fortysix(22%)patients were older than 80 years.Median age increased from the first to the last decade(from 63 to 72 years).The incidence rate increased with increasing age,but we measured a decline in recent decades for both sexes.A significant increase in the use of acetylsalicylic acid,from 5%(2/38)to 18%(8/45),was observed during the study period.Comorbidity increased significantly over the 40 years of the study,with 22%(10/45)of the patients having an American Society of Anaesthesiologists(ASA)score 4-5 in the last decade,compared to 5%(2/38)in the first decade.Thirty-nine percent(81/209)of the patients had one or more postoperative complications.Both 100-day mortality and long-term survival were associated with ASA score,without significant variations between the decades.CONCLUSION Declining incidence rates occurred in recent years,but the patients were older and had more comorbidity.The ASA score was associated with both short-term mortality and long-term survival.
文摘Peptic ulcer disease(PUD) affects 4 million people worldwide annually. The incidence of PUD has been estimated at around 1.5% to 3%. Perforated peptic ulcer(PPU) is a serious complication of PUD and patients with PPU often present with acute abdomen that carries high risk for morbidity and mortality. The lifetime prevalence of perforation in patients with PUD is about 5%. PPU carries a mortality ranging from 1.3% to 20%. Thirtyday mortality rate reaching 20% and 90-d mortality rate of up to 30% have been reported. In this review we have summarized the current evidence on PPU to update readers. This literature review includes the most updated information such as common causes, clinical features, diagnostic methods, non-operative and operative management, post-operative complications and different scoring systems of PPU. With the advancement of medical technology, PUD can now be treated with medications instead of elective surgery. The classic triad of sudden onset of abdominal pain, tachycardia and abdominal rigidity is the hallmark of PPU. Erect chest radiograph may miss 15% of cases with air under the diaphragm in patients with bowel perforation. Early diagnosis, prompt resuscitation and urgent surgical intervention are essential to improve outcomes. Exploratory laparotomy and omental patch repair remains the gold standard. Laparoscopic surgery should be considered when expertise is available. Gastrectomy is recommended in patients with large or malignant ulcer.
文摘AIM: To identify and evaluate the relative impact of H pylori infection and other risk factors on the occurrence of gastric ulcer (GU), duodenal ulcer (DU) and gastritis in Turkish patients. METHODS: A total of 4471 patients (48.3% female) out of 4863 attended the Samatya hospital in Istanbul (June 1999 - October 2003) were included. The records of H pylori status (CLO-test), endoscopic f indings of GU, DU and gastritis, personal habits (smoking, alcohol intake) and medication [non-steroidal anti-inflammatory drugs (NSAIDs), aspirin intake] were analyzed using multi-way frequency analysis. RESULTS: We have found that GU in the presence of H pylori had significant association with aspirin (P = 0.0001), alcohol (P = 0.0090) and NSAIDs (P = 0.0372). DU on the other hand had significant association with aspirin/ smoking/NSAIDs (P = 0.0259), aspirin/alcohol (P = 0.0002) and aspirin/smoking (P = 0.0233), also in the presence of H pylori. In the absence of H pylori GU had significant association with alcohol/NSAIDs (P = 0.0431), and NSAIDs (P = 0.0436). While DU in the absence of H pylori had significant association with smoking/alcohol/ NSAIDs (P = 0.0013), aspirin/NSAIDs (P = 0.0334), aspirin/alcohol (P = 0.0360). CONCLUSION: In the presence of H pylori, aspirin, alcohol and NSAIDs intake act as an independent risk factors that had an augmenting impact on the occurrence of GU and only together on the occurrence of DU in Turkish patients.
文摘AIM: To investigate and compare frequencies of serum positive cagA in patients from two separate regions of Turkey who were grouped according to the presence of peptic ulcer disease or non-ulcer dyspepsia.METHODS: One hundred and eighty Helicobacter pyloripositive patients with peptic ulcer disease or non-ulcer dyspepsia were included in the study. One hundred and fourteen patients had non-ulcer dyspepsia and 66 had peptic ulcer disease (32 with gastric ulcers and/or erosions and 34with duodenal ulcers). Each patient was tested for serum antibody to H. pylori cagA protein by enzyme immunoassay.RESULTS: The total frequency of serum positive cagA in the study group was 97.2 %. The rates in the patients with peptic ulcers and in those with non-ulcer dyspepsia were 100% and 95.6%, respectively. These results were similar to those reported in Asian studies, but higher than those that have been noted in other studies from Turkey and Western countries.CONCLUSION: The high rates of serum positive cagA in these patients with peptic ulcer disease and non-ulcer dyspepsia were similar to results reported in Asia. The fact that there was high seroum prevalence regardless of ulcer status suggests that factors other than cagA might be responsible for ulceration or other types of severe pathology in H. pylori-positive individuals.
文摘AIM:To investigate the effects of Helicobacter pylori (H pylori)eradication therapy for treatment of peptic ulcer on the incidence of gastric cancer. METHODS:A multicenter prospective cohort study was conducted between November 2000 and December 2007 in Yamagata Prefecture,Japan.The study included patients with H pylori-positive peptic ulcer who decided themselves whether to receive H pylori eradication(eradication group)or conventional antacid therapy(non-eradication group).Incidence of gastric cancer in the two groups was determined based on the results of annual endoscopy and questionnaire surveys,as well as Yamagata Prefectural Cancer Registry data,and was compared between the two groups and by results of H pylori therapy.RESULTS:A total of 4133 patients aged between 13 and 91 years(mean 52.9 years)were registered,and 56 cases of gastric cancer were identified over a mean follow-up of 5.6 years.The sex-and age-adjusted incidence ratio of gastric cancer in the eradication group, as compared with the non-eradication group,was 0.58 (95%CI:0.28-1.19)and ratios by follow-up period(<1 year,1-3 years,>3 years)were 1.16(0.27-5.00),0.50 (0.17-1.49),and 0.34(0.09-1.28),respectively.Longer follow-up tended to be associated with better prevention of gastric cancer,although not to a significant extent.No significant difference in incidence of gastric cancer was observed between patients with successful eradication therapy(32/2451 patients,1.31%)and those with treatment failure(11/639 patients,1.72%).Among patients with duodenal ulcer,which is known to be more prevalent in younger individuals,the incidence of gastric cancer was significantly less in those with successful eradication therapy(2/845 patients,0.24%)than in those with treatment failure(3/216 patients,1.39%). CONCLUSION:H pylori eradication therapy for peptic ulcer patients with a mean age of 52.9 years at registration did not significantly decrease the incidence of gastric cancer.
文摘AIM： To investigate the usefulness of anti-ulcer drugs for the prevention and treatment of low-dose aspirin-induced peptic ulcer.METHODS： Upper gastrointestinal endoscopy was performed in 68 patients receiving daily low-dose aspirin （81 or 100 rag/day）. The endoscopic findings were classified according to the Lanza score, and the scores were compared between groups categorized according to the concomitant use of anti-ulcer drugs and the types of drugs used. In another study, 31 hemorrhagic peptic ulcer patients who had been receiving low-dose aspirin were enrolled. The patients were randomly classified into the proton pump inhibitor （PPI）-treated group and the H2 receptor antagonist （H2RA）-treated group. The administration of low-dose aspirin was continued concomitantly, and endoscopic examinations were performed 8 wk later.RESULTS： The Lanza scores （mean ± SD） of the gastro-mucosal lesions were 1.0 ± 1.9 and 1.9 ± 2.3 in 8 and 16 patients receiving prevention therapy with a PPI and an H2RA, respectively. Both scores were significantly smaller than the scores in 34 patients who were not receiving prevention therapy （4.7 ± 1.0） and in 10 patients receiving cytoprotective anti-ulcer drugs （4.3± 1.6）. In the prospective study, 18 and 13 patients received a PPI and an H2RA, respectively. Endoscopic examinations revealed that the tissue in the region of the gastro-mucosal lesions had reverted to normal in all patients in the PPI-treated group and in 12 patients （92%） in the H2RA-treated group; no significant differences were observed between the groups.CONCLUSION： H2RA therapy was effective for both the prevention and treatment of low-dose aspirin-induced peptic ulcer, similar to the effects of PPIs, while cytoprotective anti-ulcer drugs were ineffective in preventing ulceration.

文摘AIM To investigate the long-term prognosis in peptic ulcer patients continuing taking antithrombotics after ulcer bleeding, and to determine the risk factors that influence the prognosis. METHODS All clinical data of peptic ulcer patients treated from January 1, 2009 to January 1, 2014 were retrospectively collected and analyzed. Patients were divided into either a continuing group to continue taking antithrombotic drugs after ulcer bleeding or a discontinuing group to discontinue antithrombotic drugs. The primary outcome of follow-up in peptic ulcer bleeding patients was recurrent bleeding, and secondary outcome was death or acute cardiovascular disease occurrence. The final date of follow-up was December 31, 2014. Basic demographic data, complications, and disease classifications were analyzed and compared by t- or χ2-test. The number of patients that achieved various outcomes was counted and analyzed statistically. A survival curve was drawn using the Kaplan-Meier method, and the differencewas compared using the log-rank test. COX regression multivariate analysis was applied to analyze risk factors for the prognosis of peptic ulcer patients. RESULTS A total of 167 patients were enrolled into this study. As for the baseline information, differences in age, smoking, alcohol abuse, and acute cardiovascular diseases were statistically significant between the continuing and discontinuing groups(70.8 ± 11.4 vs 62.4 ± 12.0, P < 0.001; 8(8.2%) vs 15(21.7%), P < 0.05; 65(66.3%) vs 13(18.8%), P < 0.001). At the end of the study, 18 patients had recurrent bleeding and three patients died or had acute cardiovascular disease in the continuing group, while four patients had recurrent bleeding and 15 patients died or had acute cardiovascular disease in the discontinuing group. The differences in these results were statistically significant(P = 0.022, P = 0.000). The Kaplan-Meier survival curve indicated that the incidence of recurrent bleeding was higher in patients in the continuing group, and the risk of death and developing acute cardiovascular disease was higher in patients in the discontinuing group(log-rank test, P = 0.000 for both). Furthermore, COX regression multivariate analysis revealed that the hazard ratio(HR) for recurrent bleeding was 2.986(95%CI: 067-8.356, P = 0.015) in the continuing group, while HR for death or acute cardiovascular disease was 5.216(95%CI: 1.035-26.278, P = 0.028).CONCLUSION After the occurrence of peptic ulcer bleeding, continuing antithrombotics increases the risk of recurrent bleeding events, while discontinuing antithrombotics would increase the risk of death and developing cardiovascular disease. This suggests that clinicians should comprehensively consider the use of antithrombotics after peptic ulcer bleeding.

文摘AIM:To evaluate the applicability of AIMS65 scores in predicting outcomes of peptic ulcer bleeding.METHODS:This was a retrospective study in a single center between January 2006 and December 2011.We enrolled 522 patients with upper gastrointestinal haemorrhage who visited the emergency room.Highrisk patients were regarded as those who had rebleeding within 30 d from the first endoscopy as well as those who died within 30 d of visiting the Emergency room.A total of 149 patients with peptic ulcer bleeding were analysed,and the AIMS65 score was used to retrospectively predict the high-risk patients.RESULTS:A total of 149 patients with peptic ulcer bleeding were analysed.The poor outcome group comprised 28 patients[male:23(82.1%)vs female:5(10.7%)]while the good outcome group included 121patients[male:93(76.9%)vs female:28(23.1%)].The mean age in each group was not significantly different.The mean serum albumin levels in the poor outcome group were slightly lower than those in the good outcome group(P=0.072).For the prediction of poor outcome,the AIMS65 score had a sensitivity of35.5%(95%CI:27.0-44.8)and a specificity of 82.1%(95%CI:63.1-93.9)at a score of 0.The AIMS65 score was insufficient for predicting outcomes in peptic ulcer bleeding(area under curve=0.571;95%CI:0.49-0.65).CONCLUSION:The AIMS65 score may therefore not be suitable for predicting clinical outcomes in peptic ulcer bleeding.Low albumin levels may be a risk factor associated with high mortality in peptic ulcer bleeding.
