Abstract
BACKGROUND/AIMS Helicobacter pylori eradication may prevent the recurrence of gastric epithelial neoplasia after endoscopic treatment. However, H. pylori eradication therapy is unlikely to prevent gastric cancer. This study determined the longterm results and clinical outcomes of patients with gastric epithelial neoplasia based on H. pylori infection status and microsatellite stability (MSS). METHODS Patients diagnosed with gastric epithelial neoplasia who underwent an endoscopic mucosal resection or submucosal dissection between 2004 and 2010 were included in this retrospective study. During the follow-up period (range, 4 to 14 years), disease recurrence was monitored, and tissue examinations were conducted for seven sets of microsatellite loci initially linked to the tumour suppressor gene locus. When H. pylori infection was identified, patients underwent eradication therapy. RESULTS The patients (n = 120) were divided into three groups: H. pylori-negative with MSS, H. pylori-positive with MSS, and microsatellite instability (MSI). After H. pylori eradication, the rate of metachronous recurrence was significantly different in the MSI (28.2%) and MSS groups (3.7%, p < 0.01). The mean duration of recurrence was 77 months (range, 24 to 139) in the MSI group. There was no recurrence after eradication therapy in patients who were positive for H. pylori in the MSS group. CONCLUSION H. pylori eradication could help prevent gastric cancer recurrence in patients with stable microsatellite loci. Careful, long-term monitoring is required in patients with unstable microsatellite loci.

Abstract
Background/Aims The rate of nonneoplastic pathology (NNP) after endoscopic resection (ER) of gastric epithelial neoplasia (GEN) has been reported to be 3%–7%. However, to date, the associations of pretreatment characteristics with NNP have not been identified. The aim of this study was to develop a predictive model for NNP after ER. Methods Among 817 patients who underwent ER for GEN, factors associated with NNP were identified by univariate and multivariate analyses. Weighted points considering the β coefficient were allocated to each variable that was significant in the multivariate analysis. The predictive score was calculated by the total points. The area under the receiver operating characteristic curve (AUROC) was calculated for the predictive score. Results The rate of NNP was 8.8%. After multivariate analysis, poor demarcation from the background, no ulceration, a flat appearance, and low-grade dysplasia were significant factors predictive of NNP. One point each was allocated for no ulcer, flat appearance, and low-grade dysplasia. Two points were allocated for poor demarcation from the background. The predictive score ranged from 0 to 5 points. Patients were categorized as being at low risk (0, 1, or 2 points) or high risk (3, 4, or 5 points) for NNP. The AUROC was 0.82 (95% confidence interval, 0.77 to 0.88; p<0.01). With a cutoff value of 2.5, the sensitivity and specificity of the score for predicting NNP were 0.72 and 0.84, respectively. Conclusions We developed a model to predict NNP after ER. Endoscopic re-biopsy or re-evaluation by pathologists is strongly recommended for the high-risk group.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) has been widely used in gastric tumor as a minimally invasive treatment. The efficacy and safety of ESD is still unclear in the elderly who have high frequency comorbidities. The aim of this study is to evaluate the efficacy and safety of ESD for gastric epithelial neoplasia in patients aged 80 years and older. METHODS Between March 2013 and July 2017, a total of 438 gastric epithelial neoplasia patients treated with ESD were analyzed. Clinical outcomes including en bloc and complete resection rates, adverse events (AE) related procedure and sedation were compared between the elderly group and the non-elderly group. RESULTS Sex, Body Mass Index, medication history and American Society of Anesthesiologists physical status did not differ between the two groups. Tumor characteristics except size of resected specimen (elderly vs. non-elderly; 36.5 ± 10.5 vs. 32.3 ± 8.7 mm, p < 0.011) did not differ. There were no significant differences in AE-related sedation. En bloc resection (elderly vs. non-elderly; 100% vs. 98.3%, p = 0.454), and complete resection rate (elderly vs. non-elderly; 93.8% vs. 96.3%, p = 0.471) did not differ significantly between the two groups. Procedure time, hospital stay, AE-related procedure and delayed bleeding were also similar between the two groups. However, procedure time of preventive hemostasis (elderly vs. non-elderly; 10.4 ± 7.7 vs. 7.4 ± 5.2 min, p = 0.040) was significantly higher in the elderly group. CONCLUSIONS ESD for gastric epithelial neoplasia is effective and safe in elderly patients ≥ 80 years as in non-elderly patients.

Abstract
Background The emergence of endoscopic submucosal dissection (ESD) made possible en bloc resection of neoplastic gastric lesions, regardless of lesion size, with reduced rates of complications and recurrence. This technique has become the preferred method for curative resection, instead of conventional endoscopic mucosal resection and surgery, when distant metastases have negligible risk. In Western countries experience with this technique has evolved quickly, with an increasing number of case series reported in the literature. This study aims to report the short- and long-term outcomes of ESD in gastric epithelial neoplastic lesions by a single operator in a Portuguese centre. Methods A retrospective analysis of all gastric ESDs in a tertiary specialised unit during a 5-year period, between May 2012 and September 2017, was performed. Results A total of 114 ESDs of gastric epithelial lesions were performed during this period; 96.5% of them were removed en bloc and 87.6% with R0 resection. A curative treatment was achieved in 83.2% of the cases. Complications occurred in 13.2% of the procedures, including early and delayed bleeding in 12 patients (10.5%) and one perforation (0.9%). With a median follow-up period of 12 months (interquartile range [IQR] = 18), 6 cases of recurrence at the previous ESD site were diagnosed: 4 residual lesions and 2 local recurrences in previous R0 resections. Residual lesions occurred more often in patients with larger lesions (median = 40.0 mm, IQR = 26 vs. median = 20.0 mm, IQR = 15, p = 0.008) and with positive horizontal margins (HMs) after resection (50.0 vs. 0.0%, Fisher exact test, p < 0.001). The cumulative incidence of metachronous gastric lesions at 34 months was 16.1%. All new lesions were effectively treated using an endoscopic technique. The disease-specific survival at 12 months was 100%. Conclusion This study showed that ESD is an effective resection technique for gastric lesions with a good safety profile, confirming other European series. Regardless, high en bloc resection positive HM is still a problem in some specimens resected by ESD. Endoscopic surveillance can detect local recurrence and new lesions during early stages, potentially treatable by endoscopy.

Abstract
Adipophilin, a lipid droplet-associated protein that regulates lipid droplet structure and formation, is expressed in a wide variety of tumors. The aims of this study were to evaluate the frequency and distribution pattern of adipophilin expression in gastric epithelial neoplasia and to correlate these variables with clinicopathological features and the mucin phenotype. We retrospectively examined 159 cases of gastric epithelial neoplasia, which were classified according to the Vienna classification system as 52 noninvasive low-grade adenoma (category 3), 65 noninvasive high-grade neoplasia (category 4), and 42 invasive neoplasia (category 5). Immunohistochemistry for adipophilin was performed, and phenotypic marker expression was determined by immunohistostaining with MUC2, MUC5AC, CD10, MUC6, and villin. Adipophilin was expressed in 41 of the 52 (79 %) category 3 cases, in 42 of the 65 (65 %) category 4 cases, and in 23 of the 42 (55 %) category 5 cases. Expression of adipophilin was only present in lesions with complete or incomplete intestinal phenotypes. Adipophilin was expressed more frequently in the surface epithelium in category 3, whereas there was a stepwise increase in cryptal staining of adipophilin from category 3 to category 5. In conclusion, adipophilin expression is closely related to the intestinal differentiation of the tumor. The pattern of immunostaining for adipophilin might be a useful new marker for discriminating adenomas from adenocarcinomas.

Abstract
Differences in pathologic diagnosis between endoscopic forceps biopsy (EFB) and endoscopic submucosal dissection (ESD) for gastric intraepithelial neoplasia (GIN) and early gastric carcinoma (EGC) in Chinese patients remain unknown. The aim of the study was to investigate risk factors for under-diagnosed pathology in initial EFB, compared to final ESD. We reviewed endoscopic and histopathologic findings for tumor location, size, macroscopic pattern, nodularity, erythema, erosion, GIN (low and high grade), and EGC diagnosed with the WHO criteria. Differences in those features between EFB and ESD were compared and risk factors for under-diagnosis by EFB were analyzed. Although concordant in most (74.9 %) cases between EFBs and ESDs, pathological diagnoses in 57 (25.1 %) cases were upgraded in ESDs. Compared to the concordant group, the lesion size ≥2 cm, and depressed and excavated patterns were significantly more frequent in the upgraded group. Further multivariate regression analysis demonstrated the depressed pattern and lesion size ≥2 cm as independent risk factors for upgraded pathology with the odds ratio of 5.778 (95 % confidence interval 2.893-11.542) and 2.535 (95 % confidence interval 1.257-5.111), respectively. Lesion size ≥2.0 cm and the depressed pattern at initial EFB were independent risk factors for pathologic upgrade to advanced diseases in ESD. Therefore, these endoscopic characteristics should be considered together with the initial EFB diagnosis to guide the optimal clinical management of patients with GIN and EGC.

Abstract
AIM: To evaluate the efficacy and safety of grasper type scissors (GTS) for endoscopic submucosal dissection (ESD) of gastric epithelial neoplasia.
METHODS: The study was performed by 4 endoscopists in 4 institutions affiliated to The Catholic University of Korea. ESD was performed in 76 consecutive patients with gastric epithelial neoplasia by using the GTS (37 patients) or the hook knife plus coagrasper (HKC) (39 patients). The complete resection rate, complication rate, total time elapsed and elapsed time per square centimeter of the dissected specimen were analyzed between the GTS and HKC group.
RESULTS: The mean age of the GTS group was 62.3 ± 11.4 years and mean age of the HKC group was 65.6 ± 10.1 years. Differentiated adenocarcinoma was found in 32.4% in the GTS group and 33.3% in the HKC group. The procedures were performed without interruption in every case in both groups. The en bloc resection rates of both groups were 100%. The total time elapsed during the procedure was 44.54 ± 21.72 min in the GTS group and 43.77 ± 21.84 min in the HKC group (P = 0.88) and the time elapsed per square centimeter of the resected lesion was 7.53 ± 6.35 min/cm2 in the GTS group and 6.92 ± 5.93 min/cm2 in the HKC group (P = 0.66). The overall complication rate was not significantly different between the two groups.
CONCLUSION: GTS is a safe and effective device for ESD compared with HKC. ESD can be performed with GTS alone, which can reduce the costs for ESD.

Abstract
Endoscopic submucosal dissection (ESD), an endoscopic procedure for the treatment of gastric epithelial neoplasia without lymph node metastases, spread rapidly, primarily in Japan, starting in the late 1990s. ESD enables en bloc resection of lesions that are difficult to resect using conventional endoscopic mucosal resection (EMR). However, in comparison to EMR, ESD requires a high level of endoscopic competence and a longer resection time. Thus, ESD is associated with a higher risk of adverse events, including intraoperative and postoperative bleeding and gastrointestinal perforation. In particular, because of a higher incidence of intraoperative bleeding with mucosal incision and submucosal dissection, which are distinctive endoscopic procedures in ESD, a strategy for endoscopic hemostasis, mainly by thermo-coagulation hemostasis using hemostatic forceps, is important. In addition, because of iatrogenic artificial ulcers that always form after ESD, endoscopic hemostasis and appropriate pharmacotherapy during the healing process are essential.

Abstract
BACKGROUND/AIMS The aim of this study was to determine the structural chromosomal aberrations, such as loss of heterozygosity (LOH) and microsatellite instability (MSI), at multiple tumor suppressor gene loci in gastric epithelial neoplasia categorized by the revised Vienna classification. METHODS All tissue samples were excised by endoscopic mucosal resection. Sixty category 3 (low-grade adenoma) tissue samples and 51 category 4 samples (high-grade adenoma and intramucosal carcinoma with adenoma) were examined at the 7 sets of microsatellite loci linked to the tumor suppressor gene locus. RESULTS For category 3 and 4 tissue samples, there were no differences in the frequencies of LOH-positive chromosomes or the extent of chromosomal loss. The Helicobacter-pylori (H. pylori)-positive rate was significantly higher in MSI-positive category 4 samples than in category 3 samples (p=0.04). The frequency of MSI positivity was significantly higher in category 4 samples than in category 3 samples (p=0.003). CONCLUSIONS H. pylori infection is associated with genetic instability of the premalignant lesion. MSI occurs in the early stages of gastric carcinogenesis and its occurrence increases during malignant transformation. Detection of MSI in premalignant gastric lesions may be a surveillant of risk of malignant transformation.
