Lam SK, Lau GKK. Proton pump inhibitors are not associated with fundic gland polyps - a systematic review that takes into consideration all known confounders. Eur J Gastroenterol Hepatol 2024; 36:831-844. [PMID: 38829941 PMCID: PMC11146189 DOI: 10.1097/meg.0000000000002788] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Accepted: 04/21/2024] [Indexed: 06/05/2024]
Abstract
Sporadic fundic gland polyps (FGPs) progress, albeit rarely, to dysplasia and cancer. Two meta-analyses, including 8 and 11 studies, concluded that proton pump inhibitors (PPIs) were associated with FGPs. Intervention is considered unnecessary when FGPs have a background of PPIs use. Both meta-analyses, however, disregarded known confounders: age, sex, endoscopy indications, study design (prospective or retrospective), duration of PPI use, and H. pylori infection. Confounders are known to invalidate meta-analyses. We followed PRIXMA guidelines and searched the literature for studies on FGPs in PPI-users and PPI-nonusers. In the 22 studies searched, we compared FGPs in PPI-users (n = 6534) and PPI-nonusers (n = 41 115). Heterogeneity was significant (Cochran Q = 277.8, P < 0.0001; I2 = 92.8%), annulling meta-analysis performed by blanket tallying. To offset the above confounders, we matched PPI-users and PPI-nonusers by (a) age and sex (n = 4300 and 29 307, respectively) and (b) their propensity scores derived from the confounders (n = 2950 and 4729, respectively). After both matching, FGPs were not significantly different between PPI-users and PPI-nonusers [odds ratio (OR) = 1.1, P = 0.3078; OR = 0.9, P = 0.3258, respectively]. Furthermore, FGP frequency did not correlate with increasing duration of PPI use (Pearson and Spearman correlation coefficients = 0.1162, 0.0386, P < 0.6064, 0.8646, respectively); it was not significantly different between any of the duration periods of observation, namely, <10, 10-20, 20-40, >40 months, nor was it significantly different between PPI-users and PPI-nonusers within each duration period (P > 0.05). We conclude that PPIs are not associated with FGPs, implying that a background history of PPI use is not a justification for nonintervention in the management of FGPs.

Abstract
Gastroesophageal reflux disease (GERD) is a common disease affecting millions of people worldwide. Proton pump inhibitors (PPI) are the most common drugs used to treat this acid-related disorder due to their high efficacy and fewer side effects. However, long-term use of these drugs can cause histopathological changes, including cystic dilation of gastric fundic glands. The present report describes a 53-year-old man with chronic GERD and daily use of PPIs 20 mg once a day for over 15 years. This case demonstrates the association between PPI and the development of fundic gland polyps.

Feasibility and efficacy of endoscopy with blue laser imaging for the detection and diagnosis of cardia polyps: A single-center randomized controlled study. J Dig Dis 2024; 25:191-199. [PMID: 38697920 DOI: 10.1111/1751-2980.13267] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Revised: 03/21/2024] [Accepted: 03/27/2024] [Indexed: 05/05/2024]
Abstract
OBJECTIVE To compare the detection rate and diagnostic accuracy of cardia polyps using endoscopy with blue laser imaging (BLI) and white-light imaging (WLI). METHODS Patients were randomly divided into the BLI group and WLI group according to the endoscopic procedures. BLI followed by WLI was conducted in the BLI group, whereas WLI followed by BLI examination was conducted in the WLI group. The number, size, microstructure, and microvascular patterns of cardia polyps detected were recorded. Biopsy of the polyps was then performed. RESULTS The detection rate of cardia polyps in the BLI group was higher than that in the WLI group (7.87% vs 4.22%, P = 0.018). The rate of overlooked lesions in the BLI group was lower than in the WLI group (0.64% vs 3.38%, P = 0.003). The diagnostic coincidence rate between magnifying BLI and histopathology was 88.16%. The sensitivity, specificity, positive predictive value and negative predictive value for the diagnosis of neoplastic lesions by magnifying endoscopy with BLI were 90.91%, 87.69%, 55.56%, and 98.28%, respectively. The most remarkable patterns for predicting inflammatory polyps were the prolonged and fine network patterns (sensitivity 71.43%, specificity 93.75%). Small round combined with honeycomb patterns were the most common among fundic gland polyps (sensitivity 80.00%, specificity 98.48%). Neoplastic lesions presented as villous or ridge-like combined with core vascular or unclear pattern for both microvascular and microstructure patterns. CONCLUSION BLI is more effective than WLI in the detection and diagnosis of cardia polyps, and magnifying endoscopy with BLI may help diagnose such lesions.

Socio-economic factors and medical conditions affecting regular stomach cancer screening in Korea: a retrospective longitudinal study using national public health data for 11 years. Public Health 2024; 227:70-77. [PMID: 38128357 DOI: 10.1016/j.puhe.2023.11.029] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 11/03/2023] [Accepted: 11/15/2023] [Indexed: 12/23/2023]
Abstract
OBJECTIVE This study aimed to explore socio-economic factors and medical conditions that affect regular stomach cancer (SC) screening among Korean adults. STUDY DESIGN This was a retrospective observational study. METHODS Study subjects were 5545 adults aged ≥40 years who participated in the 2007-2012 Korean National Health and Nutrition Examination Survey and were followed up to year 2017 based on data linking to the Korean National Health Insurance Service and Korean Health Insurance Review and Assessment. Socio-economic factors included sex, age, residential area, education, occupation, marital status, disability, public and private health insurance, service through local public health organizations, history of cancer except for SC, and family history of SC. Medical factors included six gastric lesions with the possibility of facilitating SC screening, including benign gastric neoplasm, chronic atrophic gastritis, gastric polyp, Helicobacter pylori infection, intestinal metaplasia, and peptic ulcers. The outcome was adherence to SC screening, which was divided into non-adherence, irregular adherence, and regular adherence. RESULTS After adjusting for the effects of socio-economic factors, multivariate ordinal logistic regression revealed that participants with a history of four types of gastric lesions were more likely to regularly participate in SC screening: chronic atrophic gastritis (odds ratio [OR] 1.567; 95% confidence interval [CI] = 1.276-1.923), gastric polyps (OR 1.565; 95% CI = 1.223-2.003), H. pylori infection (OR 1.637; 95% CI = 1.338-2.003), and peptic ulcer (OR 2.226; 95% CI 1.750-2.831). CONCLUSIONS To improve participation in SC screening, it is necessary to implement personalized strategies for individuals at risk for gastric cancer in addition to population-based strategies for vulnerable groups.

Abstract
OBJECTIVE In this study we aimed to compare the need for further examination with conventional gastroscopy within 1 year after magnetically assisted capsule endoscopy (MCCE) examination between patients with gastrointestinal (GI) symptoms and asymptomatic individuals. METHODS After propensity score matching analysis, 372 patients with GI symptoms and 372 asymptomatic individuals who had undergone MCCE at the First Affiliated Hospital of Sun Yat-sen University from January 1, 2019 to December 30, 2020 were retrospectively enrolled. Demographic and clinical characteristics of the participants and their MCCE and gastroscopic findings (performed within 1 year after MCCE) were analyzed. RESULTS Fifty-one (6.85%) patients underwent further examination with conventional gastroscopy within 1 year after MCCE. Those with GI symptoms were more likely to undergo conventional gastroscopy than those without (9.95% vs 3.76%, P < 0.001). Polyps were the most common finding of MCCE. The rate of conventional gastroscopy in patients with focal lesions was significantly higher than that in those without focal lesions (P < 0.05). However, such rate did not differ in the different age groups (P = 0.106). CONCLUSIONS MCCE is an optimal alternative for gastric examination, especially for large-scale screening of asymptomatic individuals. Patients with GI symptoms or focal lesions detected by MCCE are more likely to seek further examination with conventional gastroscopy for biopsy or endoscopic treatment than those without.

Abstract
BACKGROUND Gastric polyps represent an abnormal proliferation of the gastric mucosa. Chronic atrophic autoimmune gastritis (CAAG) targets parietal cells and results in hypo-achlorhydria and hypergastrinemia, which exerts a proliferative effect on the gastric mucosa. AIMS We investigate the incidence of gastric polyps in CAAG patients. METHODS This is a single-center retrospective study examining patients with confirmed CAAG from January 1990 until June 2022. Demographic, clinical, biochemical, and serological data were collected for each included patient. The histopathological characteristics of the detected polyps were recorded. RESULTS A total of 176 CAAG patients were included. Eighty-nine (50.5%) had 163 incidental polyps. Seventy-six patients (85%) had 130 non-endocrine lesions, among which 118 (90.7%) were inflammatory, 6 (4.6%) adenomatous, and 4 (3%) fundic; 33 patients (37%) had gastric neuroendocrine neoplasms (gNENs), and 21 (23.6%) both; one had MALToma and one gastric adenocarcinoma. Higher circulating levels of gastrin and chromogranin A were observed among patients with polyps (median 668 vs 893 pg/ml p = 0.0237, 146 vs 207 ng/ml p = 0.0027, respectively). CONCLUSION CAAG implies a high incidence of gNENs and exocrine lesions. Gastrin plays a possible trophic role on the mucosa. Further evidence is needed to validate its predictive role for increased polyp risk in CAAG.

Abstract
Gastric adenocarcinoma is one of the most frequent and deadly cancers worldwide. However, its incidence is variable, being higher in eastern countries where screening the general population is recommended. On the other hand, in low to intermediate-risk countries, screening the general population may not be cost-effective, and therefore, it is necessary to be aware of high-risk populations that may benefit from adequate screening and surveillance. It is not always easy to identify these individuals, leading to a late diagnosis of gastric adenocarcinoma. In this review, the authors intend to summarize the data required to identify the population at risk of sporadic or familial gastric adenocarcinoma and the beginning of screening and its surveillance, with the final aim of increasing early detection of gastric adenocarcinoma and decreasing morbimortality. The authors highlight the importance to be aware of the several hereditary syndromes and MAPS recommendations and apply screen and surveillance protocols. The high-risk syndromes to gastric adenocarcinoma are gastric adenocarcinoma and proximal polyposis of the stomach, hereditary diffuse gastric cancer, and familial intestinal gastric cancer.

Abstract
BACKGROUND/AIMS Little is known about the effect of Helicobacter pylori eradication on the recurrence of gastric hyperplastic polyps after endoscopic resection. Thus, we evaluated the recurrence rate of gastric hyperplastic polyps based on H. pylori eradication following endoscopic resection. METHODS We retrospectively reviewed the medical records of 201 patients with H. pylori infection who underwent endoscopic resection for gastric hyperplastic polyps at six medical centers. H. pylori status was assessed by histological analysis and a rapid urease test. A total of 149 patients underwent successful H. pylori eradication (eradication group), whereas 52 patients had persistent H. pylori infections (non-eradication group). The recurrence rate of gastric hyperplastic polyps and the risk factors according to H. pylori status were analyzed. RESULTS During the mean follow-up period of 18.3 months, recurrent gastric polyps developed after endoscopic resection in 10 patients (19.2% [10/52]) in the non-eradication group and 12 patients (8.1% [12/149]) in the eradication group. The cumulative incidence of recurrent gastric hyperplastic polyps was significantly higher in the non-eradication group than in the eradication group (p = 0.041, log-rank test). In the adjusted analysis, H. pylori eradication reduced the recurrence of gastric hyperplastic polyps (hazard ratio [HR], 0.42; 95% confidence interval [CI], 0.18 to 0.99), whereas anticoagulation therapy increased the risk of recurrence of gastric hyperplastic polyps (HR, 4.91; 95% CI, 1.39 to 17.28). CONCLUSION Successful eradication of H. pylori may reduce the recurrence of gastric hyperplastic polyps in patients after endoscopic mucosal resection.

Image-enhanced endoscopy for real-time differentiation between hyperplastic and fundic gland polyps in the stomach. Indian J Gastroenterol 2022; 41:599-609. [PMID: 36562941 DOI: 10.1007/s12664-022-01278-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Accepted: 06/25/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Fundic gland polyps (FGP) of stomach are benign, while some hyperplastic polyps (HP) may harbor dysplasia or malignancy. Conventional white light endoscopy (WLE) cannot reliably distinguish FGP from HP. We investigated the role of image-enhanced endoscopy in differentiating FGP from HP. METHODS Patients with gastric polyps were recruited prospectively. The characteristics of the polyps were assessed using WLE and magnification narrow band imaging (mNBI). The microsurface, intervening space (IS), and microvascular (V) features of polyps were evaluated on mNBI. The pattern characteristic of FGP and HP were determined. Histopathology of polyps was the gold standard for diagnosis. Finally, in the validation phase, five endoscopists applied the characteristic features identified in this study to predict the type of gastric polyp and their performance was assessed. RESULTS Forty-five patients with a total of 70 gastric polyps (HP-46, FGP-24) were included in this study. On mNBI, the pattern characteristic of HP included peripheral curved type of white structures forming large circular/villous loops (microsurface), enlarged intervening space, and microvessels appearing as dark patches in the intervening space (p<0.001 vs. FGP). These were noted in 95.7% HP. In contrast, 95.8% FGP had a pattern characterized by dotted/elliptical/tubular white structures (microsurface), normal width of intervening space, and microvessels surrounding the white structures in a network pattern. This IS-V pattern classification had an accuracy of >90% in the validation phase with intra-class correlation coefficient of 0.95. The accuracy of mNBI was higher than WLE (97.1% vs. 67%) in predicting the type of gastric polyp. CONCLUSIONS Image-enhanced endoscopy with mNBI (IS-V pattern) performs very well in differentiating HP from FGP.

Abstract
Gastric cancer (GC) has a good prognosis, if detected at an early stage. The intestinal subtype of GC follows a stepwise progression to carcinoma, which is treatable with early detection and intervention using high-quality endoscopy. Premalignant lesions and gastric epithelial polyps are commonly encountered in clinical practice. Surveillance of patients with premalignant gastric lesions may aid in early diagnosis of GC, and thus improve chances of survival. An expert professional workgroup was formed to summarise the current evidence and provide recommendations on the management of patients with gastric premalignant lesions in Singapore. Twenty-five recommendations were made to address screening and surveillance, strategies for detection and management of gastric premalignant lesions, management of gastric epithelial polyps, and pathological reporting of gastric premalignant lesions.

Abstract
Objective: Gastric polyps are gastric mucosal protrusions that are usually asymptomatic and detected incidentally during upper gastrointestinal system endoscopy. In this study, the incidence, location and general characteristics of gastric polyps were evaluated.
Materials and methods: Upper gastrointestinal system endoscopies performed in a tertiary hospital for a period of ten years were evaluated retrospectively. Demographic characteristics of the patients, gastroscopy indications, morphological and histological characteristics of polyps were recorded.
Results: Gastric polyps were found in 347 (1.4%) of a total of 25230 gastroscopy patients. The mean age of the patients was 61.04 ± 15.05 and 64.3% were female. 124 (35.7%) of the patients were male and 223 (64.3%) were female. The most common endoscopic indication (74.1%) of the patients with polyps was dyspepsia. Most of the polyps (55.3%) were smaller than 5 mm and the most common site was the antrum. Hyperplastic polyp (44.4%) was detected the most. 42.9% of the patients with polyps were positive for Helicobacter pylori. In addition, 58% of adenomatous polyps were accompanied by dysplasia.
Conclusion: Hyperplastic polyps were the most common polyp type in our population. Full excision of polyps over 5 mm (especially adenomatous polyps) is recommended instead of biopsy, as they may contain dysplasia foci. In addition, it was thought that taking polyps smaller than 5 mm into endoscopic follow-up without excision was more cost-effective.

Abstract
Portal hypertension (PH) is one of the most severe complications of chronic liver diseases. It is defined as an increase in pressure in the portal venous system which results in a portosystemic gradient >5 mmHg. In the western world, cirrhosis is the most frequent cause of PH, mainly due to nonalcoholic fatty liver disease and alcoholic liver disease. Patients with PH have esophageal varices in 68-73% of cases, portal hypertensive gastropathy in 51-73% and hyperplastic polyps (HPs) in 0.9-2%. Recent studies have shown that HPs found in PH patients are different from classical HPs. They constitute a new entity called portal hypertensive polyps (PHPs). The main difference between sporadic HPs and PHP is the presence of larger and more numerous vascular capillaries in the lamina propria. The clinical course of PHPs is unknown. Their physiopathology seems different from HPs: the increased congestion caused by higher portal pressure in the stomach may induce capillaries proliferation and neoangiogenesis. PHPs may be responsible for symptoms, such as pyloric obstruction, iron deficiency and anemia. Their prevalence in portal hypertensive and cirrhotic patients is from 1% to 8%. PHPs can be single or numerous, in the antrum or the gastric corpus. Their size ranges from 2 to 3 cm. PHPs seem to disappear or shrink with the treatment of PH. They should be resected in case of symptom and if >10 mm, after Helicobacter pylori eradication if present. However, their recurrence is frequent (40-79%), thus surveillance endoscopy is mandatory, at the same time as esophageal varices.

Abstract
The most common histological type of gastric cancer (GC) is gastric adenocarcinoma arising from the gastric epithelium. Less common variants include mesenchymal, lymphoproliferative and neuroendocrine neoplasms. The Lauren scheme classifies GC into intestinal type, diffuse type and mixed type. The WHO classification includes papillary, tubular, mucinous, poorly cohesive and mixed GC. Chronic atrophic gastritis (CAG) and intestinal metaplasia are recommended as common precancerous conditions. No definite precancerous condition of diffuse/poorly/undifferentiated type is recommended. Chronic superficial inflammation and hyperplasia of foveolar cells may be the focus. Presently, the management of early GC and precancerous conditions mainly relies on endoscopy including diagnosis, treatment and surveillance. Management of precancerous conditions promotes the early detection and treatment of early GC, and even prevent the occurrence of GC. In the review, precancerous conditions including CAG, metaplasia, foveolar hyperplasia and gastric hyperplastic polyps derived from the gastric epithelium have been concluded, based on the overview of gastric epithelial histological organization and its renewal.

Abstract
OBJECTIVE To investigate the endoscopic and pathological characteristics of gastric adenomatous polyps and to assess the potential risk factors for canceration of gastric adenomatous polyps. METHODS The endoscopic and pathological characteristics of the patients with gastric adenomatous polyps from January 1, 2005 to December 31, 2019 were summarized retrospectively, and the risk factors of canceration were analyzed. RESULTS A total of 125 patients with gastric adenomatous polyps were included, 51.20% of whom were females. The average age was (66.7±12.3) years. 64.80% of patients with gastric adenomatous polyps equal or more than 65 years old, and only 5.60% of the patients less than 45 years old. Adenomatous polyps were mostly distributed in the corpus and antrum with 40.80% and 32.80%, respectively. The majority of them were single (90.40%) and sessile (76.81%). 65.4% of adenomatous polyps were no more than 1.0 cm in diameter, and 23.20% of patients with adenomatous polyps were combined with hyperplastic polyps and/or fundus glandular polyps, and 1.60% had both pathological types of polyps. 58.62% (17/29) patients with hyperplastic polyps and/or fundus glandular polyps had multiple polyps. 1.60% (2/125) of the patients had gastric neuroendocrine tumor of G1 stage. Synchronous gastric cancer was detected in 13.60% (17/125) of the patients with adenomatous polyps, and the proportion of low-grade intraepithelial neoplasia was 18.40% (23/125). The main types of synchronous gastric cancer were progressive (70.59%) and undifferentiated (66.67%). Chronic atrophic gastritis with intestinal metaplasia was found in 52.80% of the patients, and autoimmune gastritis accounted for 11.20%. The positive rate of Helicobacter pylori was 21.60%. The canceration rate of gastric adenomatous polyps was 20.80%. The cancer was mainly differentiated, but there was sigmoid ring cell carcinoma as well. Diameter of >1.0 cm (OR=5.092, 95%CI: 1.447-17.923, P=0.011), uneven surface morphology and erosion (OR=13.749, 95%CI: 1.072-176.339, P=0.044) were independent risk factors of adenomatous polyps. CONCLUSION The synchronous gastric cancer is common and the canceration of gastric adenomatous polyps is high with diameter and surface morphology as independent risk factors. We should pay attention to the identification of the pathological types of polyps and the evaluation of the whole gastric mucosa during the endoscopic examination.

Abstract
The application value of image mosaic algorithm (IMA) based CT imaging technology in the analysis of pathological characteristics of gastric polyp (GP) patients was explored in this work. 588 cases of GP patients in the hospital were selected as the research objects, and CT images based on IMA were adopted for examination. The patient's basic information, image performance, and gastroscopy results were recorded. The results showed that the absolute mean bright error (AMBE) index and information entropy of the IMA are 0.0625 and 7.0385, respectively. The clinical symptoms of patients were mostly abdominal pain (21.4%), abdominal distension (15.6%), and sour regurgitation (17.8%). The common size of GP was no more than 0.5 cm, and the common type was Yamada type II. There were notable differences between single and multiple GPs of different pathological types (P < 0.05). Proliferative polyps were mostly found in the stomach and antrum, while fundus gland polyps were mostly in the stomach and fundus. There was significant difference between the growth location of the hyperplastic polyp and basal gland polyp (P < 0.05). In summary, the CT images of IMA proposed in this paper can not only realize image splicing effectively but also were superior to the traditional SIFT method in the quality of splicing image and were conducive to the analysis of the pathological characteristics of GP patients, which had significant clinical promotion value.

Abstract
Objectives: The paper uses image stitching algorithm to understand the clinical and pathological characteristics of gastric polyps under gastroscope, and provides objective basis for the clinical diagnosis and treatment of gastric polyps and nursing intervention. Methods: The endoscopic, pathological data and surgical conditions of 111 patients with gastric polyps detected in the hospital from January 2017 to August 2019 were retrospectively analyzed. Results: The elderly patients (≥60 years old) in this group were those with high incidence of gastric polyps (56.8%); 80 patients with single polyps (72.1%), 31 patients with multiple polyps (27.9%); polyps were mainly located in the stomach (53.2%); polyps diameter ≤0.5cm are more common (69.4%); polyps are mainly hyperplastic polyps (40.5%) and inflammatory polyps in 37 cases (33.3%). Polyps were removed by biopsy forceps in 30 cases, endoscopic submucosal injection of 0.9% NaCl solution combined with high-frequency electrosurgical removal of 54 cases, endoscopic mucosal resection (EMR) in 6 cases, and endoscopic submucosal dissection (ESD) in treatment of the 4 cases, the remaining 17 cases were treated with surgery, and 12 patients were followed up, 2 of whom relapsed. Conclusion: Gastric polyps are small in diameter and mostly single; polyps are mainly located in the stomach body, mainly hyperplastic polyps; treatment methods are mostly endoscopic resection, and there is a possibility of recurrence after polypectomy, and follow-up should be strengthened. Full preparation before the operation, close cooperation during the operation, and careful postoperative care are important links to ensure the safety of the operation and reduce complications such as upper gastrointestinal bleeding.

Abstract
Introduction Hyperplastic polyps represent 30-93% of all gastric epithelial polyps. They are generally detected as innocuous incidental findings; however, they have a risk of neoplastic transformation and recurrence. Frequency and risk factors for neoplastic transformation and recurrence are not well established and are fields of ongoing interest. This study aims to evaluate the frequency of and identify the risk factors for recurrence and neoplastic change of gastric hyperplastic polyps (GHP). Methods A single-centre retrospective cohort study including consecutive patients who underwent endoscopic resection of GHP from January 2009 to June 2020. Demographic, endoscopic, and histopathologic data was retrieved from the electronic medical records. Results A total of 195 patients were included (56% women; median age 67 [35-87] years). The median size of GHP was 10 (3-50) mm, 62% (n = 120) were sessile, 61% (n = 119) were located in the antrum, and 36% (n = 71) had synchronous lesions. Recurrence rate after endoscopic resection was 23% (n = 26). In multivariate analysis, antrum location was the only risk factor for recurrence (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.1-8.1). Overall, 5.1% (n = 10) GHP showed neoplastic transformation, with low-grade dysplasia in 5, high-grade dysplasia in 4, and adenocarcinoma in 1. In multivariate analysis, a size >25 mm (OR 84; 95% CI 7.4-954) and the presence of intestinal metaplasia (OR 7.6; 95% CI 1.0-55) and dysplasia (OR 86; 95% CI 10-741) in adjacent mucosa were associated with an increased risk of neoplastic transformation. Recurrence was not associated with neoplastic transformation (OR 1.1; 95% CI 0.2-5.9). Discussion Our results confirmed the risk of recurrence and neoplastic transformation of GHP. Antrum location was a predictor of recurrence. The risk of neoplastic change was increased in large lesions and with intestinal metaplasia and dysplasia in adjacent mucosa. More frequent endoscopic surveillance may be required in these subgroups of GHP.

Abstract
BACKGROUND There is increasing evidence that the eradication of Helicobacter pylori leads to the regression of gastric hyperplastic polyps (GHPs). We performed a systematic review with a meta-analysis of randomized controlled trials and observational studies that assessed the effects of eradication. MATERIALS AND METHODS We searched the PubMed, Embase, and Cochrane Central Register of Controlled Trials databases for relevant studies with a combination of the terms "Helicobacter pylori" and "polyps." The risk ratio was used to compare the effect of H. pylori eradication/treatment on GHP. We also calculated the pooled disappearance rate of GHP in the H. pylori eradication/treatment group and persistent infection group. RESULTS We analyzed data from 6 studies, including 3 RCTs. A total of 58/394 patients were included in the H. pylori treatment/successful eradication group, and 57/302 patients were included in the H. pylori untreated/persistent infection group. The pooled rate of GHP elimination after H. pylori treatment/successful eradication was 59% (95% CI, 43%-75%)/79% (95% CI, 72%-86%). H. pylori treatment/successful eradication significantly increased the GHP elimination rate [ITT: (pooled rate: 58% vs. 0%, RR =22.24, 95% CI, 4.51- 109.78, p = 0.0001), PP: (pooled rate: 65% vs. 0%, RR =22.25, 95% CI, 4.52- 109.37, p = 0.0001)/(pooled rate: 79% vs. 9%, RR =26.87, 95% CI, 1.34-540.5, p = 0.03)]. CONCLUSIONS Our meta-analysis showed that after the eradication of H. pylori, most GHPs are eliminated. Moreover, the treatment/successful eradication of H. pylori increased the GHP elimination rate by more than 20 times that in the control group.

Abstract
INTRODUCTION The aim of this study was to study the relationship between the formation of gastric fundic gland polyp and gastric hyperplastic polyp (HP) and the changes of gastric juice microenvironment. METHODS The proton-pump inhibitor (PPI) applications to patients were recorded. Gastric juices and biopsy polyps were collected for pathological examination, H. pylori tests, biomarkers, and MUC1, MUC2, MUC5AC expression measurement. RESULTS Among 34,892 patients, the detection rate of gastric fundic gland polyps was significantly higher than that of gastric HPs (p < 0.01). The incidence rate of gastric fundic gland polyp and gastric HP in PPI users (n = 3,886) was higher than that of non-PPI users (p < 0.01). The occurrence of polyp was positively related to the duration of PPI application and the H. pylori-positive rate. The bile reflux rate between fundic gland polys group (17.61%) and HPs (28.67%) was significantly different (p < 0.01). The levels of gastric juice Gastrin-17, epidermal growth factor (EGF) and MUC2 from patients with gastric fundic gland polyps and gastric HPs were higher than those in the control group (p < 0.01). However, patients with gastric fundic gland polyps and HPs had significantly lower gastric juice PGE2 and MUC5AC (p < 0.01). CONCLUSION PPI application, H. pylori infection, and bile reflux are the potential risk factors for formation of fundic gland polyps and HPs. The potential mechanism of polyps' formation can be related to the levels of Gastrin-17, EGF, MUC2, PGE2, and MUC5AC in gastric juice.

Abstract
OBJECTIVE: In our study, we aimed to evaluate the endoscopic features such as prevalence and localization of polypoid lesions determined by us using esophagogastroduodenoscopy and histopathological characteristics of biopsy specimens taken in detail. METHODS: The data of 19,560 patients undergoing upper gastrointestinal endoscopy for any reason between 2009 and 2015 in our endoscopy unit were screened retrospectively and endoscopic and histopathological findings were analyzed in detail. RESULTS: In our study, the polypoid lesion was detected in 1.60% (n=313) of 19,560 patients. The most common localization of the polypoid lesions was determined to be gastric localization (n=301, 96.2%) and antrum with a rate of 33.5% (n=105). When 272 patients in whom biopsy specimen could be taken was investigated, the most frequently seen lesion was polyp (n=115, 43.4%). Hyperplastic polyps (n=81, 29.8%) were the most frequently seen type among all polyps. In histopathological evaluation of the lesions, the prevalence rates of intestinal metaplasia (IM), surrounding tissue IM, atrophy, dysplasia, and neoplasia (adenocarcinoma, squamous cell carcinoma, gastrointestinal stromal tumor, neuroendocrine tumor, and metastatic tumor) among premalignant lesions were determined to be 16.9%, 11.2%, 4.1%, 1.1%, and 3.7%, respectively. CONCLUSION: Polypoid lesions can be seen in endoscopic investigations. In histopathological investigations, while the vast majority of these lesions are benign polyps, some of them are diagnosed as premalignant or malignant lesions. In our study, we determined malignant lesions higher than the similar studies in the literature. This condition shows how effective endoscopic procedure and histopathological evaluation are of vital importance.

Abstract
Sedation esophagogastroduodenoscopy (EGD) has become more prevalent in many countries. However, owing to the limitation of health insurance payment for sedation EGD in Taiwan, non-sedation EGD still accounts for the majority of cases. This study was aimed to explore the differences between the sedation and non-sedation groups in terms of endoscopic findings, such as detection rate of gastric polyp of any size, number of detected gastric polyps, and location of the gastric polyps detected.We enrolled 10,940 patients who underwent EGD between January 1, 2016 and December 31, 2016 at the Tri-Service General Hospital; among the patients, 1900 received intravenous sedation (IVS) and 9040 did not. The data reviewed included demographics, parameters of the polyp (number, size, and location), and pathology.Compared with the non-sedation group, the sedation group had a higher overall polyp detection rate (P < .001); a greater number of detected polyps (Odds ratio 1.50, P = .007); and a higher detection rate of smaller polyps, such as fundic gland polyp, and hyperplastic polyp (P < .001). Among the pathological findings, gastric neuroendocrine tumor (NET) was detected using EGD in 2 cases and manifested as small polyps (<0.05 cm), and it showed significantly better detection rates in the sedation EGD group than in the non-sedation EGD group (P = .002).Sedation EGD could enhance a patients willingness and cooperation during EGD. Furthermore, sedation EGD increased the detection rates of small gastric polyps and was more likely to enable identification of unusual findings, such as gastric NET.

Abstract
This review provides an overview of different types of gastric epithelial polyps. The polyps are classified based on their cell or epithelial compartment of origin. Some of these polyps can be considered reactive or nonneoplastic, whereas others are neoplastic in origin, are sometimes associated with a hereditary polyposis/cancer syndrome, and may have malignant potential. The aim of this review is to provide a pragmatic overview for the practicing pathologist about how to correctly diagnose and deal with gastric epithelial polyps and when (not) to ponder, and when (not) to panic.

Abstract
INTRODUCTION Gastric polypoid lesions (GPL) are endoscopic findings whose histological nature is difficult to determine with white-light endoscopy. Hyperplastic polyps (HP), type-1 gastric carcinoids (T1-GC) and adenomas are the most frequent GPL needing different management. Narrow-band imaging (NBI) has high accuracy for gastric malignant lesions but few studies assessed whether GPL display specific NBI characteristics. We aimed to investigate the endoscopic NBI appearances of GPL. MATERIALS AND METHODS During gastroscopies, images of GPL were recorded, and lesions were removed for histological evaluation. Two endoscopists blindly reviewed the digital images and registered the endoscopic NBI appearances on a specific check-list. GPL were categorized in HP, adenomas and T1-GC using histology as gold standard. RESULTS Overall 52 GPL, observed in 40 patients [F55%; age 63 (36-85) years], were included: 29 (55.8%) HP; 18 (34.6%) T1-GC; 5 (9.6%) adenomas. The median size was seven (2-35) mm. A regular circular mucosal pattern was more frequently observed in HP and T1-GC compared to adenomas (P < 0.001). T1-GC showed a central erosion in 77.8% (P < 0.001 versus HP) with a clear demarcation line in 33.3%. Adenomas had tubule-villous mucosal pattern in 80% (P = 0.01 versus other lesions). CONCLUSION NBI analysis of the mucosal pattern seems to be effective to endoscopically discriminate between adenomas and HP while the main characteristic of T1-GC seems to be the presence of a central erosion, sometimes with demarcation line. The endoscopic NBI characterization of GPL may contribute to optimize the management of these lesions.

Abstract
Autoimmune metaplastic atrophic gastritis (AMAG) previously called type A chronic gastritis is an immune-mediated chronic inflammatory disease characterized by the immune-mediated destruction of gastric parietal cells in the fundus and body of the stomach. AMAG is an uncommon disease that often presents with hematological manifestations and may lead to the development of gastric carcinoids. AMAG can be reliably diagnosed by antibody assays, functional serology, and histology. The understanding of the disease process is essential for the detection and management of hematological complications and gastric lesions. The prevalence of AMAG is on the rise and subsequently gastric carcinoids. However, this association is not well recognized in clinical practice, and management and diagnosis of AMAG and gastric carcinoids remain suboptimal. In the current review, we will discuss the pathophysiology, diagnosis and management of AMAG. A special focus is given to the association between AMAG and gastric carcinoids. We will also review the management options of type 1 gastric carcinoids.

Abstract
Hyperplastic polyps are the most frequent benign epithelial gastric polyps. Although they are considered nonneoplastic, some cases have been reported with focal adenocarcinoma. We present the case of a 59-year-old woman with a sessile lesion of 15 mm on the distal gastric body associated with an extensive atrophic gastritis. Magnifying endoscopy with Fuji Intelligent Color Enhancement (FICE) revealed an irregular microsurface pattern at the apex, suggesting malignancy. A mucosectomy was performed. The histopathology revealed that the base corresponded to a hyperplastic polyp, where a tubular adenoma with high-grade dysplasia was established, with focal well-differentiated intramucosal tubular adenocarcinoma.

Abstract
BACKGROUND AND AIMS Gastric cancer (GC) is the fourth most common cancer and the fourth leading cause of cancer death worldwide. In some Asian countries, screening EGD has greatly improved the survival rate. However, patients' discomfort and the need for sedation may limit adherence to screening programs. Previous studies have shown good tolerance and good agreement of magnetically controlled capsule gastroscopy (MCCG) with EGD. This study was designed to assess the application of MCCG in GC detection in an asymptomatic population. METHODS In this observational cohort study, 3182 asymptomatic individuals undergoing MCCG in 99 participating medical examination centers from April to December 2016 were enrolled. Patients with ulcers and suspected malignancies were referred for gastroscopy and biopsy. The detection rate of GC and focal lesions were used to explore the application of MCCG in asymptomatic individuals. RESULTS Seven patients (0.22%) were diagnosed with GC among the enrolled 3182 individuals, accounting for 0.74% (7/948) in patients over 50 years. No gender disparity was observed. EGD and biopsy confirmed adenocarcinoma in all cases of suspected malignancy. Benign polyps, gastric ulcers, and submucosal tumors were found in 10.4%, 4.9%, and 3.6% of patients, respectively. There was a trend for the prevalence of focal lesions to increase with age. MCCG examination proved to be safe. CONCLUSIONS MCCG can detect cancer and benign lesions and is safe and clinically feasible in a large population. Studies of its role in a screening program should be considered.

Abstract
The subject of Helicobacter pylori continues to elicit worldwide interest in many research fields. Epidemiological data suggest that the prevalence of the infection is decreasing in Western/developed countries and even in some developing regions, but this is masked by the high prevalence in the most populous regions. Chronic gastritis, caused invariably by the bacterium, was again classified in Kyoto and Helicobacter pylori-associated gastritis was included as a distinct entity. The prevalence of peptic ulcers is decreasing, but bleeding ulcers are a challenging problem, with stable mortality levels even in the endoscopic era. With the extended use of endoscopy, gastric polyps (GP) have become more prevalent: some are associated with the infection, some are not. Autoimmune and Helicobacter-induced gastritis can share common pathogenetic mechanisms. Gastric cancer (GC) is ranked highly on mortality lists worldwide. Its surgical treatment has registered some progress though. Little, if any improvement has been achieved in the medical treatment of advanced GC. With proper organization, GC seems a preventable disease. In spite of many guidelines, the Pan-European registry of Helicobacter pylori management shows that eradication rates obtained in many places are suboptimal. A new therapeutic regimen was compiled with promising pilot results. The results obtained with vonaprazan are limited to Asia. New avenues of both antibiotic and non-antibiotic treatments are expected to accelerate the eradication of this ulcerogenic and carcinogenic bacterium.
