Efficacy and safety of polaprezinc in the treatment of gastric ulcer: A multicenter, randomized, double-blind, double-dummy, positive-controlled clinical trial. Med Eng Phys 2022; 110:103860. [PMID: 35999163 DOI: 10.1016/j.medengphy.2022.103860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 07/05/2022] [Accepted: 07/26/2022] [Indexed: 02/07/2023]
Abstract
OBJECTIVE To investigate the clinical efficacy and safety of polaprezinc compared with rebamipide in the treatment of gastric ulcers (GU). METHODS GU patients (n = 224) from 10 clinical centers were prospectively enrolled and randomly divided into a control (n = 113) or test (n = 111) group. The control group was treated with rebamipide tablets, while the test group was treated with polaprezinc. The primary endpoint was the effective treatment rate, which was confirmed by gastroscopy after 8 weeks of treatment. The secondary efficacy endpoint was the improvement rate of gastrointestinal symptoms after 4 and 8 weeks of treatment. RESULTS The basic characteristics of the two groups were well balanced. For the primary efficacy endpoint, the effective rates confirmed by gastroscopy, after treatment for the test and control groups were 81.48% and 74.31% (P = 0.1557), respectively. After 4 and 8 weeks of treatments, both treatment groups had comparable improvements rates in gastrointestinal symptoms (test vs. control: 44.44% vs. 39.45% [P = 0.4559] and 81.48% vs. 77.06% [P = 0.4223]). Further, the two groups had similar adverse events and reactions to the study drugs. CONCLUSION These findings suggest that the efficacy and safety of polaprezinc were similar to those of rebamipide in the treatment of GU.

Abstract
Objectives: To evaluate the effectiveness and safety of a newly designed self-assembling gel in treating ESD-induced gastric ulcers in patients.Methods: This open-label, multicenter, randomized controlled trial enrolled patients who underwent ESD between September 2020 and May 2021. Patients were randomized (1:1) to receive the gel (applied to cover the entire ulcer bed under endoscopic guidance immediately after ESD; gel group) or not (control group). The primary outcome was the ulcer healing rate at 28 days. And the secondary outcomes were the delayed bleeding, changes in the ulcer stage, and adverse events.Results: Finally, 125 patients (mean age, 63.7 years; 70 [56.0%] males) were enrolled. The ulcer healing rate was higher in the gel group than in the control group at 28 days (96.9 ± 4.1% vs. 94.7 ± 5.0%; p = 0.001). The ulcer reduction rate at 28 days differed significantly (p < 0.001) between ulcers with majority gel coverage (99.8%), ulcers with minority gel coverage (96.2%), and ulcers with no gel coverage (98.0%). Delayed bleeding was found in 1/63 gel-treated patients (1.6%) versus 5/62 controls (8.1%). A1-stage ulcers were found in 16/63 patients in the gel group versus 44/62 patients in the control group (25.4% vs. 71.0%, p < 0.001) at 3–5 days.Conclusion: The newly developed self-assembling gel was safe and effective in accelerating gastric ulcer healing in patients after ESD.Clinical Trial Registration: UMIN Clinical Trials Registry System (registration number, ChiCTR2100052935).

Abstract
OBJECTIVES Both potassium-competitive acid blockers (P-CABs) and proton pump inhibitors (PPIs) are known to be protective against bleeding after gastric endoscopic dissection (ESD) for early gastric cancers. The aim was to compare the effect of PPI and P-CAB treatment against bleeding after gastric ESD. MATERIALS AND METHODS This was a single-center, retrospective analysis. Among 541 patients who underwent gastric ESD during the period from 2014 to 2019, we recruited subjects who were treated with PPIs (intravenous lansoprazole followed by oral esomeprazole) or a P-CAB before and after ESD. The incidence of post-ESD bleeding was compared between treatment groups. The risks associated with post-ESD bleeding were examined by univariate and multivariate analyses after propensity score-matching. RESULTS The overall incidence of post-ESD bleeding was not significantly different between patients treated with PPIs (n = 362) and those treated with a P-CAB (n = 156) (3.0% vs 2.6%, respectively; p = .77). Even after propensity score matching (n = 153 in each group), the incidence was not significantly different between groups (2.6% vs 2.6%, respectively; p = 1.00). A multivariate analysis revealed that antithrombotic therapy (OR 4.85, 95% CI 1.14-20.57) was an independent factor associated with post-ESD bleeding. CONCLUSIONS The incidence of post gastric ESD bleeding is not different between patients treated with PPI and patients treated with P-CAB. Antithrombotic therapy is an independent risk factor associated with post-ESD bleeding.

Rebamipide with Proton Pump Inhibitors (PPIs) versus PPIs Alone for the Treatment of Endoscopic Submucosal Dissection-Induced Ulcers: A Meta-analysis. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7196782. [PMID: 33062694 PMCID: PMC7539128 DOI: 10.1155/2020/7196782] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Accepted: 08/24/2020] [Indexed: 11/18/2022]
Abstract
Objective To contrast the effect of rebamipide with proton pump inhibitors (PPIs) versus PPIs alone for the treatment of endoscopic submucosal dissection (ESD-) induced ulcers. Methods PubMed, Embase, the Cochrane library, the WanFang database, and China National Knowledge Infrastructure (CNKI) were searched to identify studies that met the inclusion criteria. Results Nine randomized controlled trials (RCTs) were recognized, including 1170 patients. In general, rebamipide plus PPIs acted better than PPIs alone against ESD-induced ulcers at four weeks (RR = 1.42, 95% CI: 1.13-1.78, P = 0.003) but showed no significant differences at eight weeks (RR = 1.03, 95% CI: 0.97-1.10, P = 0.315). The use of rebamipide plus PPIs was superior to PPIs alone for ESD-induced ulcers greater than 20 mm in size (20-40 mm: RR = 1.98, 95% CI: 1.22-3.23, P = 0.006; >40 mm: RR = 5.14, 95% CI: 1.49-17.74, P = 0.010). In addition, rebamipide plus PPI therapy was discovered to be significantly more effective than PPIs alone for lower ESD-induced ulcers (RR = 1.82, 95% CI: 1.04-3.20, P = 0.037). There were no significant differences between the treatment groups with the ulcer reduction rate. Conclusion Evidences now available show rebamipide plus PPIs is practical for protecting against ESD-induced ulcers at four weeks but not at eight weeks, especially large ulcers (>20 mm). However, we still need more high-quality RCTs in the future to supplement our conclusions.

Percent reduction of the ulcer size at 4 weeks is a predictor of the complete healing of endoscopic submucosal dissection-induced gastric ulcers. Arab J Gastroenterol 2020; 21:183-188. [PMID: 32798188 DOI: 10.1016/j.ajg.2020.07.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2018] [Revised: 03/17/2020] [Accepted: 07/09/2020] [Indexed: 01/04/2023]
Abstract
BACKGROUND AND STUDY AIMS Endoscopic submucosal dissection (ESD) is widely used as a treatment modality for gastric mucosal neoplasia. While proton pump inhibitors (PPIs) have been used for the control of artificial ulcers created by ESD (ESD-ulcers), complete healing of the ulcers is not always achieved in all the cases. The purpose of this study was to identify the clinical factors that are predictive of refractory ESD-ulcers. PATIENTS AND METHODS We recruited 90 patients with 102 artificial ulcers that formed after the patients underwent ESD for gastric tumours. All the patients received a 20-mg capsule of esomeprazole daily until the 56th day after ESD, and underwent endoscopy at 1, 4, 6 and 8 weeks after the ESD. We analyzed the clinical factors that were associated with the complete healing at 8 weeks after the ESD (CH-8w). The ulcers in the scar stage were defined as the complete healing in this study. RESULTS Of the 102 ESD-ulcers, 16.7% failed to show complete healing after the 8 weeks of PPI therapy. Univariate analysis identified the percent reduction of the ulcer size at 4 weeks after ESD (PR-4w) as being significantly associated with CH-8w. Multivariate analysis identified ulcer location in the lower-third of the stomach and PR-4w > 95% as being independently correlated with the CH-8w (odds ratio = 4.86 and 7.89, respectively). Analysis of the area under the receiver operating characteristic (AUROC) curve demonstrated that the AUROC curve of PR-4w for predicting the CH-8w was 0.78. CONCLUSION Based on the results of our study, endoscopic observation at 4 weeks after ESD would help in the early identification of refractory ESD-ulcers.

Abstract
Objectives: This study aimed to compare the efficacy of various anti-ulcer medications in preventing delayed bleeding and promoting ulcer healing after ESD.Methods: Asystematic search was conducted for articles up to August2019. The treatments of iatrogenic ulcer were analyzed by Bayesian network meta-analysis.Results: The analysis included 28 studies. Six treatments were compared. For the prevention of delayed bleeding, potassium-competitive acid blocker (P-CAB) alone was superior to proton-pump inhibitor (PPI) alone [RR = 1.02, 95%CI (1.00, 1.05)]. Treatments based on P-CAB tended to be better than the non-P-CAB groups [RR = 1.05, 95%CI (1.03, 1.07)]. Concerning the ulcer healing rate at 4 weeks, the combined treatment of PPI and mucoprotective agent (MP) was superior to PPI alone [RR = 1.81, 95%CI (1.19, 2.76)] and P-CAB alone [RR = 2.75, 95%CI (1.02, 7.44)]. At 8 weeks, PPI+MP and P-CAB+MP tend to be superior to than the other four groups. The healing effect of MP-based therapies was better than that of non-MP groups at 4 weeks [RR = 1.63, 95%CI (1.32, 2.01)] and 8 weeks [RR = 1.06, 95%CI (1.02, 1.11)].Conclusion: P-CAB may prevent delayed bleeding, but not significantly. MP agents have the potential to heal post-ESD ulcers.

Abstract
Objective Gastric endoscopic submucosal dissection (ESD) is currently a standard procedure, and proton pump inhibitors (PPIs) are most commonly used to treat post-ESD ulcers. Vonoprazan, a potassium-competitive acid blocker (P-CAB), reportedly inhibits gastric acid secretions more effectively than PPIs. Combination therapy of a PPI plus rebamipide is effective for treating larger ulcers. Our goal was to evaluate the effects of vonoprazan plus rebamipide compared to esomeprazole plus rebamipide for the treatment of post-ESD ulcers. Methods First, vonoprazan plus rebamipide (V group) or esomeprazole plus rebamipide (E group) was orally administered to subjects for eight weeks. We then evaluated the ulcer healing process at four and eight weeks after the procedure using a gastric ulcer stage system and by measuring the ulcer size. Patients A total of 84 patients who underwent ESD for gastric neoplasms between September 2015 and December 2017 in Tsuchiura Kyodo General Hospital were included in this randomized controlled trial. Results The ulcer scar rates at week 4 in the V group (n=43) and E groups (n=39) were 20.9% and 15.4%, while those at week 8 were 90.7% and 92.3%, respectively. The ulcer reduction rates at week 4 in the V and E groups were 94.6% and 93.8%, and those at week 8 were 99.7% and 99.3%, respectively. The ulcer scar rates and reduction rates were not significantly different between the two groups. Conclusion Combination therapy consisting of vonoprazan plus rebamipide was not superior to that of esomeprazole plus rebamipide for post-ESD ulcer healing (UMIN000019516).

Abstract
BACKGROUND Steroid therapy is primarily used to prevent esophageal stricture after endoscopic submucosal dissection (ESD). However, esophageal stricture can still occur after preventive therapy, and the effect of preventive steroid therapy cannot be predicted before stricture formation. This study aimed to clarify the risk factors for esophageal stricture after preventive steroid therapy. METHODS This was a retrospective study conducted at three institutions. From January 2011 to February 2018, 28 large-sized SENs in 26 patients who had a mucosal defect that involved more than three-quarters of the esophageal circumference were enrolled. We classified white coats on artificial ulcers after esophageal ESD into three groups (thin, moderately thick, thick) based on endoscopic images obtained on postoperative day 7. RESULTS The white coat status on the artificial ulcer after ESD was a significant risk factor for post-ESD stricture (p < 0.05). The stricture rates in patients with thin, moderately thick and thick white coats were 10.0, 36.4 and 85.7%, respectively. When thin and moderately thick white coats were combined, the stricture rate was 23.8%. The rate of stricture in lesions with thick white coats was significantly higher than that in patients with thin white coats or thin to moderately thick white coats (p < 0.05). The multivariate analysis revealed that the white coat status was an independent factor related to esophageal stricture (odds ratio 13.70, 95% confidence interval 1.22-154.0; p = 0.034). CONCLUSIONS The thickness of the white coat is a useful marker for predicting the risk of post-ESD stricture and the effectiveness of preventive steroid therapy.

[PMID: 29870582 DOI: 10.1111/jgh.14305] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2018] [Revised: 05/21/2018] [Accepted: 05/27/2018] [Indexed: 12/09/2022]
Abstract
BACKGROUND Currently, it is still unclear whether adding a mucoprotective agent to a proton pump inhibitor (PPI) results in better outcomes compared with using a PPI alone in patients with post-gastric endoscopic submucosal dissection (ESD) ulcers. This study aimed to examine the efficacy of PPI alone versus combination treatment in healing of post-gastric ESD ulcers, as well as on delayed bleeding and amount of blood transfused. METHODS A systematic search of MEDLINE, EMBASE, Cochrane, and ISI Web of knowledge databases, up until May 2017, for randomized trials comparing PPI alone versus PPI plus a mucoprotective drug in achieving ulcer healing in patients undergoing gastric ESD was performed. The primary outcome is scarring stage on endoscopic assessment at 4 or 8 weeks after gastric ESD. RESULTS From an initial 3071 citations, eight articles (n = 953 lesions from 934 patients) were analyzed. Patients receiving combination treatment achieved a scarring stage significantly more often than those on a PPIs alone at 4 or 8 weeks after ESD, (risk ratio = 1.36, 95% CI; 1.06-1.75). No study reported amount of blood transfused. There were no significant between treatment-group differences in terms of delayed bleeding (risk ratio = 0.58, 95% CI; 0.17-1.99). Neither location of ulcer nor Helicobacter pylori infection was related to ulcer scarring stage. CONCLUSION The limited evidences suggested combination treatment may be more effective in accelerating the process of ulcer healing in patients undergoing gastric ESD than the use of PPI alone, but does not appear to alter delayed bleeding risk.

J Dig Dis 2018; 19:657-663. [PMID: 30267481 DOI: 10.1111/1751-2980.12672] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2018] [Revised: 08/10/2018] [Accepted: 09/25/2018] [Indexed: 12/11/2022]
Abstract
OBJECTIVE Surgicel (Fibrillar), i.e. oxidized regenerated cellulose, is used to control oozing bleeding after surgery, but few studies have assessed its effect on complications after endoscopic treatment. The aim of this study was to evaluate the efficacy of Surgicel for preventing bleeding after endoscopic submucosal dissection (ESD) for gastric epithelial tumors. METHODS From November 2012 to December 2013 patients scheduled for ESD of gastric epithelial tumors were prospectively enrolled in this study. Patients were assigned randomly to monotherapy with a proton pump inhibitor (PPI) (the MT group) or combination therapy with Surgicel and histamine-2 receptor antagonist (H2 RA) (the CT group) for preventing bleeding after ESD. Major bleeding rates and changes in hemoglobin at 1 and 7 days after ESD were evaluated. RESULTS Among the 157 patients enrolled (111 men, 46 women), 78 were assigned to the MT group and 79 to the CT group; finally, 72 and 74 patients were included in the MT and CT groups. The major bleeding rate was lower in the CT group (6/74, 8.1%) than in the MT group (12/72, 16.7%), but the difference was not significant (P = 0.354). The change in hemoglobin was significantly less marked in the CT group than the MT group 1 day after ESD ([-6.2 ± 9.0] g/L vs [-8.9 ± 6.2] g/L, P = 0.045). CONCLUSIONS Combination therapy with Surgicel and an H2 RA decreased the rate of bleeding similarly to PPI. Adding Surgicel to H2 RA could be considered for patients with bleeding tendencies, or who require continuous antiplatelet therapy to prevent bleeding after ESD.

Comparative efficacy of various anti-ulcer medications after gastric endoscopic submucosal dissection: a systematic review and network meta-analysis. Surg Endosc 2018; 33:1271-1283. [PMID: 30167955 DOI: 10.1007/s00464-018-6409-4] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Accepted: 08/24/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND The comparative efficacy of various anti-ulcer medications after gastric endoscopic submucosal dissection (ESD) has not been fully evaluated. Recently, vonoprazan, a novel potassium-competitive acid blocker, has also been used in ulcer treatment after ESD. METHODS We searched for all relevant randomized controlled trials examining the efficacy of anti-ulcer medications after gastric ESD, published through October 2017. Healing of iatrogenic ulcers was investigated at 4-8 weeks after ESD. A network meta-analysis was performed to calculate the network estimates. RESULTS Twenty-one studies with 2005 patients were included. Concerning the comparative efficacy for ulcer healing at 4 weeks after ESD, no network inconsistency was identified (Cochran's Q-test, df = 10, P = 0.13; I2 = 34%). A combination therapy of proton-pump inhibitor (PPI) and muco-protective agent was superior to PPI alone [risk ratio (RR) (95% confidence interval, CI) 1.69 (1.20-2.39)]. The combination therapy of PPI and muco-protective agents tended to be superior to vonoprazan [RR (95% CI) 1.98 (0.99-3.94)]. There was no difference of ulcer healing effect between PPI and vonoprazan [RR (95% CI) PPI vs. vonoprazan, 1.17 (0.64-2.12)]. Concerning the ulcer healing rate at 8 weeks after ESD, however, vonoprazan was superior to PPI [RR (95% CI) 1.27 (1.03-1.56)]. Additionally, vonoprazan tended to be superior to the combination therapy of PPI and muco-protective agent [RR (95% CI) 1.20 (0.96-1.51)]. CONCLUSIONS A combination therapy of PPI and muco-protective agent was superior to PPI alone for ulcer healing at 4 weeks after ESD. In the ulcer healing effect at 8 weeks after ESD, vonoprazan was superior to PPI.

Abstract
BACKGROUND The optimal treatment regimen or the duration of treatment for an endoscopic submucosal dissection (ESD)-induced gastric ulcer has not been established. The aim of this study was to assess the efficacy of novel proton-pump inhibitor, ilaprazole, for the treatment of ESD-induced gastric ulcer. METHODS This was a prospective, open-label, randomized multicenter study. Between June 2015 and March 2018, a total of 176 patients (178 lesions) who underwent ESD for a gastric neoplasm were randomly allocated to receive the oral proton-pump inhibitor ilaprazole 20 mg or rabeprazole 20 mg daily for 8 weeks. The primary outcome was the ulcer healing rate at 4 and 8 weeks. RESULTS A total of 155 (157 lesions) and 154 patients (156 lesions) were included in the modified intention-to-treat (mITT) and per-protocol analyses, respectively. There was no significant difference in the ulcer healing rate (ilaprazole vs. rabeprazole, 97.4% vs. 97.0 p = 0.78 at 4 weeks, 100% vs. 100%, p = 0.95 at 8 weeks in the mITT analysis) or stage of ulcer (scar stage, 25.6% vs. 17.7%, p = 0.25 at 4 weeks, 92.3% vs. 88.6%, p = 0.59 at 8 weeks in the mITT analysis) between the treatment groups. The quality of ulcer healing was not significantly different between the two groups. No independent predictive factor for higher-quality ulcer healing was found in the multivariate analysis. CONCLUSIONS According to this trial, ilaprazole and rabeprazole showed no significant difference in the healing of artificial gastric ulcers. Most of the ulcers achieved complete healing within 4-8 weeks. TRIAL REGISTRATION ClinicalTrial.gov NCT02638584.

Abstract
Background Vonoprazan affords more clinical benefits than proton pump inhibitors (PPIs) during the healing of gastroduodenal ulcers. However, it remains controversial whether vonoprazan is more effective than PPIs when used to heal artificial ulcers arising after endoscopic submucosal dissection (ESD). Aim This study investigated the effects of vonoprazan compared with esomeprazole on the healing of post-ESD artificial ulcers. Methods Sixty patients who underwent gastric ESD between May 2015 and May 2017 were randomized to treatment with vonoprazan (V group) or esomeprazole (E group) for 8 weeks. Upper endoscopy was performed at 4 and 8 weeks after ESD, and drug effects were estimated based on the ulcer healing rates and shrinkage rates. Results Fifty-three patients were analyzed. The respective 4- and 8-week ulcer healing rates did not differ significantly between V and E groups (8.0 versus 11.5%, P = 0.669; 88.9 versus 84.6%, P = 0.420). Similarly, the respective 4- and 8-week ulcer shrinkage rates did not differ significantly between V and E groups (96.8 versus 97.5%, P = 0.656; 100 versus 100%, P = 0.257). Conclusion The healing of artificial ulcers after ESD did not differ using vonoprazan or esomeprazole. Both vonoprazan and esomeprazole were effective when used to promote artificial ulcer healing after ESD.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) is a promising method for the resection of superficial gastric neoplasms. Vonoprazan is a novel potassium-competitive acid blocker (P-CAB) that is currently considered as a potential alternative to proton pump inhibitors (PPIs) for the treatment of acid-related diseases. However, the utility of vonoprazan in ESD-related ulcers is unclear. Therefore, we compared the short-term efficacies of vonoprazan and the PPI lansoprazole in ESD-related ulcer healing during the first two weeks following intervention. METHODS This study included 115 superficial gastric neoplasms that were treated by ESD at Hiraka General Hospital between April 2015 and January 2017. Patients treated with P-CAB (20 mg vonoprazan, n = 62) or PPI (30 mg lansoprazole, n = 53) were compared using propensity-score matching analysis. Primary outcome was rate of ulcer reduction at two weeks after ESD. Secondary outcomes were coverage ratio of ulcer base by granulation tissue and incidence of postoperative bleeding. RESULTS The rate of ulcer reduction was significantly higher (median [range], 80.6% [67.6%-94.5%] vs. 62.7% [33.4%-85.2%]; p < .0001) and coverage ratio of the ulcer base by granulation tissue was significantly accelerated (median [range], 84.1% [67.7%-95.3%] vs. 61.9% [12.1%-90.1%]; P < 0.0001) in the P-CAB group compared with the PPI group. Postoperative bleeding was not observed in either group. CONCLUSIONS P-CAB achieved rapid artificial ulcer healing with promotion of granulation tissue formation. However, conventional PPI with initial intravenous infusion might be sufficient for prevention of postoperative bleeding following gastric ESD.

Abstract
BACKGROUND AND AIM Proton pump inhibitors are effective for the treatment of gastric ulcers after endoscopic submucosal dissection (ESD). However, the most excellent therapy is controversial. Vonoprazan, an active potassium-competitive acid blocker, has a strong gastric acid secretion inhibitory effect, but its efficacy for the treatment of post-ESD gastric ulcers is unclear. Herein, we aimed to determine the healing effect of vonoprazan on post-ESD gastric ulcers. METHODS We carried out a prospective randomized controlled trial examining 92 patients who had undergone ESD for the treatment of gastric neoplasms between April 2015 and June 2016 at Machida Municipal Hospital. Patients were treated with 20 mg/day vonoprazan (V group) or 20 mg/day esomeprazole (E group) for 8 weeks. We evaluated the 8-week cure rate for artificial ulcers and any complications after ESD. RESULTS A total of 80 patients (median age, 73.5 years; 71.3% male) were analyzed. Cure rate for the V group was significantly higher than that for the E group (94.9% [37/39] vs 78.0% [32/41], respectively; P = 0.049). In a multivariate analysis, only vonoprazan was correlated with ulcer healing (odds ratio = 6.33; 95% CI = 1.21-33.20; P = 0.029). Delayed bleeding was experienced only in the E group (7.3% [3/41]), but no significant difference compared with the V group was observed (P = 0.241). CONCLUSION Vonoprazan was significantly superior to esomeprazole for the healing of post-ESD gastric ulcers and should be considered as a treatment of first choice.

Abstract
BACKGROUND/AIMS Few studies have classified risk factors according to the onset time of bleeding after endoscopic submucosal dissection (post-ESD bleeding). METHODS We studied 1767 consecutive lesions in patients who underwent ESD for early gastric cancer from December 2006 through June 2016. Patients who had a remnant stomach or who had undergone reconstruction with a gastric tube were excluded. Post-ESD bleeding was classified into acute bleeding (0-5 days after ESD) and delayed bleeding (6 or more days after ESD), and the risk factors for each type of bleeding were compared. RESULTS Post-ESD bleeding occurred in 150 (8.5%) of 1767 lesions. Bleeding was acute in 129 lesions (7.3%) and delayed in 21 (1.2%). Acute post-ESD bleeding was frequently associated with lesions located in the distal stomach, expanded indications or non-indicated lesions, a specimen diameter of ≥40 mm, and antithrombotic therapy. Delayed post-ESD bleeding was often associated with lesions located in the proximal stomach, hemodialysis, and antithrombotic therapy. Among 334 lesions in patients who received antithrombotic therapy, post-ESD bleeding occurred in 47 lesions (14.1%). Independent risk factors for post-ESD bleeding were a specimen diameter of ≥40 mm and treatment with 2 or more antithrombotic agents. CONCLUSIONS Acute post-ESD bleeding and delayed post-ESD bleeding were associated with different clinical characteristics. Antithrombotic therapy is a risk factor for post-ESD bleeding in both the acute and delayed phases.

Abstract
BACKGROUND Endoscopic resection for early gastric cancer (EGC) plays a central role in the treatment of EGC in Japan. However, there is still room for improvement, and it is necessary to summarize the recently obtained knowledge from Japan for further improvement. METHODS We conducted a PubMed search to select relevant articles in the 5 years until September 18, 2016, using the keywords "gastric cancer" and "endoscopic treatment," "endoscopic submucosal dissection," "endoscopic mucosal resection," or "polypectomy" and filtering article types as "clinical study" or "clinical trial." RESULTS Among the 329 articles selected automatically from the keywords "polypectomy" (1 article), "endoscopic mucosal resection" (29 articles), "endoscopic submucosal dissection" (77 articles), and "endoscopic treatment" (222 articles) in combination with "gastric cancer," 32 relevant articles from Japanese investigators were chosen. Seven articles were categorized into "equipment," 4 into "preparation and sedation," 17 into "complications and their prevention," and 4 into "therapeutic outcomes." Among them, CO2 insufflation, propofol sedation, and how to prevent post-endoscopic submucosal dissection (ESD) ulcer bleeding and achieve post-ESD ulcer healing were intensively investigated. Long-term outcomes of endoscopic mucosal resection and ESD were also reported as favorable outcomes. CONCLUSIONS Endoscopic resection for EGC is still developing toward an ideal form, pursuing a more reliable, safer, and faster minimally invasive treatment.

The aim of the present study was to determine the healing effect of vonoprazan on artificial ulcers post-gastric ESD relative to PPI. METHODS Thirty-five patients who underwent gastric ESD between April and November 2015 were treated with vonoprazan 20 mg/day for 4 weeks and subsequently underwent endoscopy for evaluation of ulcer size (V group). Ulcer contraction rate was determined by the following formula: ([ESD specimen size] - [ulcer size at 4 weeks after ESD])/(ESD specimen size) × 100%. We compared the results with those of a historical control group treated with esomeprazole 20 mg/day for 4 weeks after gastric ESD and subsequently measured their ulcer size (33 patients, E group) by propensity score-matching methods. RESULTS Sixty-two subjects were enrolled after propensity score-matching. Ulcer contraction rate at 4 weeks after ESD in the V group was significantly higher than that of the E group (97.7 ± 3.2% vs 94.5 ± 6.7%, respectively, P = 0.025). Number of subjects with a scar-stage ulcer (100% contraction rate) tended to be higher in the V group relative to the E group (32% [10 of 31] vs 13% [4 of 31], respectively, P = 0.070, McNemar's chi-squared test). CONCLUSION Vonoprazan has a faster post-gastric ESD artificial ulcer contraction rate than esomeprazole. Vonoprazan may supersede PPI in treating post-ESD artificial ulcers of the stomach.

World J Gastrointest Endosc 2016; 8:716-722. [PMID: 27909552 PMCID: PMC5114461 DOI: 10.4253/wjge.v8.i19.716] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2016] [Revised: 08/01/2016] [Accepted: 09/18/2016] [Indexed: 02/05/2023] Open
Abstract
AIM To compare the healing effects of vonoprazan and lansoprazole on gastric ulcers induced by endoscopic submucosal dissection (ESD).
METHODS Data were obtained from a total of 26 patients. Fourteen patients were randomized to the vonoprazan group and 12 were randomized to the lansoprazole group. Patients were administered either 20 mg vonoprazan or 30 mg lansoprazole per day after ESD. Endoscopic images just after ESD, on day 8, and on day 28 were used for the evaluation of the shrinking rate of ESD ulcers. The shrinking rates and the incidence of delayed bleeding were compared between the 2 groups.
RESULTS The shrinking rates of ESD ulcers on day 8 [vonoprazan group: 61.8% (range: 24.0%-91.1%), lansoprazole group: 71.3% (range: 25.2%-88.6%)] and on day 28 [vonoprazan group: 95.3% (range: 76.2%-100%), lansoprazole group: 97.2% (range: 81.1%-99.8%)] were not statistically different between the 2 groups. On day 28, most of the ulcers in both groups healed to more than 90%, whereas 3 of 14 (21.4%) in the vonoprazan group and 1 of 12 (8.3%) in the lansoprazole group had delayed ulcer healing, which was not statistically different (P = 0.356). The frequency of delayed bleeding was 0 in the both groups. Taken together, there were no significant differences between the two drug groups.
CONCLUSION Our study indicates that vonoprazan is potent for the management of ESD ulcers although lansoprazole is also sufficient and cost-effective.

Abstract
Background Rebamipide is a gastroprotective agent with promising results against gastric damage induced by non-steroidal anti-inflammatory drugs. The present study evaluated if rebamipide protects against naproxen-induced gastric damage in healthy volunteers. Changes in gastric PGE2 tissue concentration were also evaluated. Methods After a preliminary endoscopy to rule out previous gastric macroscopic damage, twenty-four healthy volunteers of both sexes were divided into 2 groups. One group received sodium naproxen 550 mg b.i.d. plus placebo for 7 days, while the other group received sodium naproxen 550 mg b.i.d. plus rebamipide 100 mg b.i.d. At the end of treatment, a new endoscopy was performed. Gastric macroscopic damage was evaluated by the Cryer score and by the modified Lanza score. The primary outcome measure of the trial was the macroscopic damage observed in each treatment group at the end of treatment. Biopsies were collected at both endoscopies for PGE2 quantification and histopathological analysis (secondary outcomes). Tissue PGE2 was quantified by ELISA. The randomization sequence was generated using 3 blocks of 8 subjects each. Volunteers and endoscopists were blind to whether they were receiving rebamipide or placebo. Results All recruited volunteers completed the trial. Sodium naproxen induced gastric damage in both groups. At the end of the study, median Cryer score was 4 in both groups (Difference = 0; 95%CI = −1 to 0; p = 0.728). In the placebo group, the mean tissue PGE2 concentration was 1005 ± 129 pg/mL before treatment and 241 ± 41 pg/mL after treatment (p < 0.001). In the rebamipide group, the mean tissue PGE2 concentration was 999 ± 109 pg/mL before treatment, and 168 ± 13 pg/mL after treatment (p < 0.001). There was no difference in mean tissue PGE2 between the two groups (difference = 5; 95%CI from −334.870 to 345.650; p = 0.975). No significant change was observed at the histopathological evaluation, despite the evident macroscopic damage induced by naproxen. Conclusion Rebamipide does not protect against naproxen-induced gastric damage in healthy volunteers. Trial registration ClinicalTrials.gov, NCT02632812. Registered 14 December 2015.

Factors associated with healing of artificial ulcer after endoscopic submucosal dissection with reference to Helicobacter pylori infection, CYP2C19 genotype, and tumor location: Multicenter randomized trial. Dig Endosc 2016; 28:162-72. [PMID: 26331711 DOI: 10.1111/den.12544] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2015] [Revised: 08/27/2015] [Accepted: 08/31/2015] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIM Healing speed of peptic ulcer is affected by a number of factors, including Helicobacter pylori (H. pylori) infection and intragastric pH. Acid inhibition exerted by proton pump inhibitors differs by CYP2C19 genotype. Herein, we investigated whether healing speed of artificial ulcers formed after endoscopic submucosal dissection (ESD) was influenced by H. pylori infection, CYP2C19 genotype, or other factors. METHODS A total of 96 H. pylori-positive patients with gastric tumors scheduled for ESD were randomly assigned to receive eradication therapy for H. pylori before ESD (pre-ESD eradication) (n = 44) or after (post-ESD eradication) (n = 52). Patients received eradication therapy consisting of lansoprazole 30 mg, amoxicillin 750 mg, and clarithromycin 200 mg twice daily for 1 week. After ESD, lansoprazole 30 mg was given once daily for 8 weeks. Ulcer size was endoscopically measured on the next day and at 4 and 8 weeks after ESD. RESULTS Mean reduction rate of artificial ulcer area in the pre-ESD eradication group was 94.7% ± 5.5% at 4 weeks, which was similar to that in the post-ESD eradication group (94.7% ± 6.7%, P = 0.987), irrespective of CYP2C19 genotype. In multivariate analyses, location of gastric tumor (middle and upper, odds ratio: 4.05, 95% CI: 1.620-10.230, P = 0.003) was a factor for 97% reduction of artificial ulcer area at 4 weeks post-ESD, but CYP2C19 genotype and H. pylori infection were not. CONCLUSION Healing speed of ESD-induced artificial ulcer was affected by tumor location, but not by time of H. pylori eradication, resected size, or CYP2C19 genotype.

Abstract
BACKGROUND AND AIM Endoscopic submucosal dissection (ESD) is the established therapy for superficial gastrointestinal neoplasms. However, management of the artificial ulcers associated with ESD has become important and the relationship between ulcer healing factors and treatment is still unclear. We aimed to evaluate ESD-related artificial ulcer reduction ratio at 4 weeks to assess factors associating with ulcer healing after ESD that may lead to optimal treatment. METHODS Between January 2009 and December 2013, a total of 375 lesions fulfilled the expanded criteria for ESD. We defined ulcer reduction rate <90% as (A) poor-healing group; and rate ≥90% as (B) well-healing group. After exclusion, 328 lesions were divided into two groups and analyzed. These two groups were compared based on clinicopathological/endoscopic features, concomitant drugs, and treatment. RESULTS Ulcer reduction rate was significantly correlated with factors related to the ESD procedure (i.e. procedure time, submucosal fibrosis, and injury of the proper muscle layer, in univariate analysis. Multivariate logistic regression analysis showed that submucosal fibrosis (F2) (P = 0.03; OR, 16.46; 95% CI, 1.31-206.73) and injury of the proper muscle layer (P = 0.01; OR, 4.27; 95% CI, 2.04-8.92) were statistically significant predictors of delayed healing. CONCLUSION This single-center retrospective study indicated that ESD-induced artificial ulcer healing was affected by submucosal fibrosis and injury of the proper muscle layer, which induced damage to the muscle layer. Therefore, the preferable pharmacotherapy can be determined on completion of the ESD procedure.

Abstract
AIM: To compare the efficacy of proton pump inhibitors (PPIs) plus rebamipide vs PPIs alone for the treatment of ulcers induced by endoscopic submucosal dissection (ESD).
METHODS: Keyword and MeSH searches of PubMed, EMBASE, OVID, Cochrane Library, Wanfang Database and CNKI from the inception of each database to February 2015 were performed to identify all available randomized controlled trials comparing the effects of PPIs plus rebamidide and PPIs alone on healing ulcers after ESD. Two independent reviewers assessed the studies for inclusion and exclusion based on methodological quality criteria.
RESULTS: A total of five studies involving 670 patients were included. The pooled data suggested a significantly higher rate of ulcer healing after ESD among patients treated with PPIs plus rebamipide than those treated with PPIs alone (OR = 2.68, 95%CI: 1.81-3.97). The combination therapy was found to be significantly more effective than the use of PPIs alone for all ESD ulcers greater than 20 mm in size (OR = 4.77, 95%CI: 2.22-10.26). The ulcer reduction rate in the combination group was higher than that in the PPI alone group after four weeks of treatment (MD = 68.39, 95%CI: 35.73-101.05).
CONCLUSION: The results of this meta-analysis indicate that the combination therapy of PPIs plus rebamipide is more efficient than PPI monotherapy in healing ESD-induced ulcer, particularly large ulcers. However, more high-quality trials are needed to confirm these findings.

Abstract
Mucosal protective agents may improve healing of patients with endoscopic submucosal dissection-induced ulcers. The present study systematically evaluated published clinical trials to determine whether combined therapeutic use of mucosal protective agents and proton pump inhibitors can improve the outcome of patients with endoscopic submucosal dissection-induced ulcers compared to treatment with proton pump inhibitors alone. PubMed, the Cochrane Library, and the Igaku-Chuo-Zasshi database were searched to identify eligible randomized trials for systematic review. We identified 11 randomized trials for inclusion in our study (1,160 patients). Pooled endoscopic submucosal dissection-induced ulcer healing rates were 45.8% and 34.4% for patients with or without mucosal protective agents, respectively. The odds ratio was 2.28 (95% confidence interval, 1.57-3.31) with no significant study heterogeneity. In conclusion, the systematic review and meta-analysis showed that the combined therapeutic use of proton pump inhibitors and mucosal protective agents improved healing rates of endoscopic submucosal dissection-induced ulcers compared to treatment with proton pump inhibitor monotherapy.

Abstract
BACKGROUND Although post-endoscopic submucosal dissection (ESD) iatrogenic ulcer is known to heal faster than peptic ulcer, some iatrogenic ulcers show delayed healing. The aim of this study was to clarify risk factors of delayed ulcer healing after gastric ESD. METHODS We retrospectively reviewed medical records of all patients who had ESD for gastric neoplasms (866 adenomas and 814 early gastric cancers) between January 2005 and February 2011. RESULTS Of 1680 subjects, 95 had delayed ulcer healing in 3-month follow-up. Multivariate analysis showed that diabetes (OR 1.743; 95% CI 1.017-2.989, p = 0.043), coagulation abnormality (OR 3.195; 95% CI 1.535-6.650, p = 0.002), specimen size greater than 4 cm (OR 2.999; 95% CI 1.603-5.611, p = 0.001), and electrocoagulation (OR 7.149; 95% CI 1.738-29.411, p = 0.006) were revealed to be independent risk factors of delayed ulcer healing. Meanwhile, persistent Helicobacter pylori infection was not related to the delayed ulcer healing. CONCLUSIONS Large iatrogenic ulcer by ESD with massive hemostasis, especially in patients with diabetes mellitus or coagulation abnormalities, tends to take more than 3 months to heal. For such cases, initial dosage increment of PPI or addition of other anti-ulcer agents after ESD may be beneficial.

Abstract
AIM: To investigate the optimum period of treatment for post endoscopic submucosal dissection (ESD) ulcers.
METHODS: Patients who underwent ESD for gastric cancer were randomized to two groups and treated with esomeprazole 20 mg per day for 4 wk (4W group) or 2 wk (2W group). At 4 wk after ESD, we measured the size of the artificial ulcers by endoscopy and determined the ulcer healing rate, compared with the size of the ESD specimens. This randomized controlled trial study was approved by our ethics committee and registered in the UMIN Clinical Trial Registry.
RESULTS: A total of 60 consecutive patients were included in the study. All patients received rebamipide 300 mg per day for 4 wk. One patient in 2W group who showed bleeding within two weeks and received endoscopic treatment was excluded from further analysis. The numbers of patients with ulcers in the healing/scar stage in the 2W and 4W groups at 4 wk after ESD were 20/6 and 28/5, respectively, with no significant difference. The ulcer healing rate in the 2W and 4W groups were 96.1% [95% confidence interval (CI): 94.6%-97.55] vs 94.8% (95%CI: 92.6%-97.1%), respectively, with no statistical difference (UMIN000006951).
CONCLUSION: Two-wk treatment with a proton pump inhibitor is as effective as four-week treatment for healing post ESD ulcers.

Abstract
The popular fruit tree of Annona muricata L. (Annonaceae), known as soursop and graviola, is a widely distributed plant in Central and South America and tropical countries. Leaves of A. muricata have been reported to possess antioxidant and anti-inflammatory activities. In this study, the gastroprotective effects of ethyl acetate extract of A. muricata leaves (EEAM) were investigated against ethanol-induced gastric injury models in rats. The acute toxicity test of EEAM in rats, carried out in two doses of 1 g/kg and 2 g/kg, showed the safety of this plant, even at the highest dose of 2 g/kg. The antiulcer study in rats (five groups, n=6) was performed with two doses of EEAM (200 mg/kg and 400 mg/kg) and with omeprazole (20 mg/kg), as a standard antiulcer drug. Gross and histological features showed the antiulcerogenic characterizations of EEAM. There was significant suppression on the ulcer lesion index of rats pretreated with EEAM, which was comparable to the omeprazole effect in the omeprazole control group. Oral administration of EEAM to rats caused a significant increase in the level of nitric oxide and antioxidant activities, including catalase, glutathione, and superoxide dismutase associated with attenuation in gastric acidity, and compensatory effect on the loss of gastric wall mucus. In addition, pretreatment of rats with EEAM caused significant reduction in the level of malondialdehyde, as a marker for oxidative stress, associated with an increase in prostaglandin E2 activity. Immunohistochemical staining also demonstrated that EEAM induced the downregulation of Bax and upregulation of Hsp70 proteins after pretreatment. Collectively, the present results suggest that EEAM has a promising antiulcer potential, which could be attributed to its suppressive effect against oxidative damage and preservative effect toward gastric wall mucus.

Abstract
Proton pump inhibitor (PPI) was the main prescription for gastric ulcer after endoscopic submucosal dissection (ESD). Some randomized controlled trials showed that a combination of rebamipide and PPI appears to be more efficient than PPI alone for the treatment of ESD-induced gastric ulcer. However, the sample sizes in these trials were limited and the conclusions were underpowered.This meta-analysis was conducted with 5 randomized controlled trials using the combination of rebamipide and PPI for healing ESD-induced ulcer compared with PPI monotherapy. Relevant studies were searched via MEDLINE, PubMed, Embase, and Cochrane Library databases by using terms such as "rebamipide," "proton pump inhibitor," "endoscopic submucosal dissection," "drug therapy," and "gastric ulcer or artificial ulcer."Five studies were included in this meta-analysis. The number of total patients was 626, with 317 patients in the combination group and 309 patients in the PPI alone group. The heterogeneity among these 5 studies was low (I = 22%, P = 0.28). All 5 studies considered scarring stage 1 rate as a primary endpoint, and the scarring stage 1 rate in combination group (115/317) was higher than that in PPI alone group (63/309) (odds ratio 2.61, 95% confidence interval [CI] 1.76-3.88). The mean difference of initial ulcer size between 2 groups was -4.46 (95% CI -266.61 to -257.69, P = 0.97), but it enlarged to 68.38 (95% CI 35.72-101.05, P < 0.00001) in the 4th week.This meta-analysis demonstrates that combination therapy is more efficient than PPI monotherapy in healing ESD-induced gastric ulcer.

Abstract
Rebamipide was initially developed and approved for use in treating gastric ulcers and lesions associated with gastritis. Discovery of its ability to increase gastric mucin led to investigations of its effect on ocular surface mucin and the subsequent development for use in dry eye patients. Investigations have confirmed that rebamipide increases corneal and conjunctival mucin-like substances along with improving corneal and conjunctival injury. Clinically, rebamipide ophthalmic suspensions can effectively treat tear deficiency and mucin-caused corneal epithelial damage, and can restore the microstructure responsible for tear stability. Topical rebamipide has also been shown to be effective in treating other ocular surface disorders such as lagophthalmos, lid wiper epitheliopathy, and persistent corneal erosion. Rebamipide's ability to modify epithelial cell function, improve tear stability, and suppress inflammation in the absence of any known major side effects suggest that it may be a beneficial first drug of choice for severe dry eye treatment and other ocular surface disorders. This review summarizes the history and development of this innovative dry eye treatment from its initial use as an effective stomach medication to its current use in the treatment of dry eye in Japan.

Abstract
OBJECTIVE To compare the efficacy of proton pump inhibitors (PPIs) with rebamipide versus PPIs alone for the treatment of ulcers after endoscopic submucosal dissection (ESD). METHODS PubMed, Web of Science, Medline, Embase, the Cochrane Central Register of Controlled Trials and China Naitonal Knowledge Infrastructure were searched up to the end of October 2013 in order to identify all randomized controlled trials reporting the effects of PPIs plus rebamipide on healing ulcers after ESD. The outcome measurement was complete ulcer healing. RESULTS A total of six studies involving 724 patients were included. The pooled data suggested a significantly higher rate of ulcer healing after endoscopic therapy among patients treated with PPIs plus rebamipide than among those treated with PPIs alone [odds ratio (OR)=2.40, 95% confidence interval (CI): 1.68-3.44]. The subgroup analysis showed PPI plus rebamipide therapy to be more effective in healing ESD-induced ulcers than treatment with PPIs alone after both four (OR=2.22, 95%CI: 1.53-3.24) and eight weeks of treatment (OR=3.19, 95%CI: 1.22-8.31). In addition, the combination therapy was found to be significantly more effective than the use of PPIs alone for all ESD ulcers greater than 20 mm in size (OR=4.77, 95%CI: 2.22-10.26). There were no significant differences between the treatment groups with regard to ulcer location (low, middle or upper stomach) or the presence of absence of H. pylori infection. No serious adverse events were observed in either group. CONCLUSION The results of this meta-analysis suggest that treatment with PPIs plus rebamipide is superior to PPI monotherapy for healing ESD-induced ulcers over four weeks, particularly large ulcers. However, more well-designed trials are needed to confirm these findings.

Abstract
Although techniques and instruments for endoscopic submucosal dissection (ESD) have improved, bleeding is still the most common complication. Minimizing the occurrence of bleeding is important because blood can interfere with subsequent procedures. Generally, ESD-related bleeding can be divided into intraprocedural and postprocedural bleedings. Postprocedural bleeding can be further classified into early post-ESD bleeding which occurs within 48 hours after ESD and late post-ESD bleeding which occurs later than 48 hours after ESD. A basic principle for avoiding intraprocedural bleeding is to watch for vessels and coagulate them before cutting. Several countertraction devices have been designed to minimize intraprocedural bleeding. Methods for reducing postprocedural bleeding include administration of proton-pump inhibitors or prophylactic coagulation after ESD. Medical adhesive spray such as n-butyl-2-cyanoacrylate is also an option for preventing postprocedural bleeding. Various endoscopic treatment modalities are used for both intraprocedural and postprocedural bleeding. However, hemoclipping is infrequently used during ESD because the clips interfere with subsequent resection. Bleeding that occurs as a result of ESD can usually be managed easily. Nonetheless, more effective ways to prevent bleeding, including reliable ESD techniques, must be developed.

Abstract
AIM: To prospectively compare the healing rates of endoscopic submucosal dissection (ESD)-induced ulcers treated with either a proton-pump inhibitor (PPI) or rebamipide.
METHODS: We examined 90 patients with early gastric cancer who had undergone ESD. All patients were administered an intravenous infusion of the PPI lansoprazole (20 mg) every 12 h for 2 d, followed by oral administration of lansoprazole (30 mg/d, 5 d). After 7-d treatment, the patients were randomly assigned to 2 groups and received either lansoprazole (30 mg/d orally, n = 45; PPI group) or rebamipide (300 mg orally, three times a day; n = 45; rebamipide group). At 4 and 8 wk after ESD, the ulcer outcomes in the 2 groups were compared.
RESULTS: No significant differences were noted in patient age, underlying disease, tumor location, Helicobacter pylori infection rate, or ESD-induced ulcer size between the 2 groups. At both 4 and 8 wk, the healing rates of ESD-induced ulcers were similar in the PPI-treated and the rebamipide-treated patients (4 wk: PPI, 27.2%; rebamipide, 33.3%; P = 0.5341; 8 wk: PPI, 90.9%; rebamipide, 93.3%; P = 0.6710). At 8 wk, the rates of granulation lesions following ulcer healing were significantly higher in the PPI-treated group (13.6%) than in the rebamipide-treated group (0.0%; P = 0.0103). Ulcer-related symptoms were similar in the 2 treatment groups at 8 wk. The medication cost of 8-wk treatment with the PPI was 10945 yen vs 4889 yen for rebamipide. No ulcer bleeding or complications due to the drugs were observed in either treatment group.
CONCLUSION: The healing rate of ESD-induced ulcers was similar with rebamipide or PPI treatment; however, rebamipide treatment is more cost-effective and prevents granulation lesions following ulcer healing.

Abstract
BACKGROUND Although endoscopic submucosal dissection (ESD)-induced ulcers heal faster and recur less often than non-iatrogenic gastric ulcers, the optimal dosage and duration of proton pump inhibitor treatment for ESD-induced ulcers remain unclear. AIMS To evaluate the efficacy of half-dose rabeprazole on endoscopic submucosal dissection-induced ulcer compared with standard dose rabeprazole. METHODS The study was a prospective randomized controlled double-blind trial at a single tertiary hospital. A total of 80 patients who underwent ESD for gastric neoplasia were enrolled. Of these patients, 10 were not followed to completion. Final analysis included the remaining 70 patients. Rabeprazole 20 or 10 mg, depending on randomization, was given orally for 4 weeks after ESD. RESULTS Of the 70 patients, 45 (64 %) were men, and the median age was 65.2 ± 9.7 years. The mean ESD-induced ulcer area was 673 mm(2). No significant differences in ulcer area reduction ratio (p = 0.49) or ulcer-related symptoms (p = 0.91) were observed between the two groups at 4 weeks after ESD. CONCLUSION For ESD-induced ulcers, treatment with 10 mg of rabeprazole daily produces a similar outcome as 20 mg of rabeprazole with regard to healing efficacy and symptom resolution.

Abstract
Objectives Endoscopic submucosal dissection (ESD) is useful for treating gastric tumors. Several trials have shown the efficacy of 4 or 8 weeks of proton pump inhibitor (PPI) administration for post-ESD ulcers. However, if the size of the post-ESD ulcer is larger than predicted, PPI administration alone might not be sufficient for the ulcer to heal within 4 weeks. There is no report about the efficacy of post-ESD gastric ulcers by esomeprazole. We examined retrospectively the efficacy of a combination therapy of esomeprazole plus rebamipide, a mucosal-protective antiulcer drug, on the acceleration of post-ESD ulcer healing comparing with omeprazole plus rebamipide. Methods: We reviewed the medical records of patients who underwent ESD for gastric neoplasia. We conducted a case-control study to compare the healing rates within 4 weeks effected by esomeprazole plus rebamipide (group E) and omeprazole plus rebamipide (group O). The sizes of the artificial ulcers were divided into normal-sized or large-sized. Results: The baseline characteristics did not differ significantly between the two groups except age and sex. Stage S1 disease was observed in 27.6% and 38.7% of patients after 4 weeks of treatment in the group E and O, respectively. In large-sized artificial ulcers, the healing rate of stage S1 in group E is significantly higher than that in group O in 4 weeks.(25% VS 0%:P = 0.02) Conclusions: The safety and efficacy profiles of esomeprazole plus rebamipide and omeprazole and rebamipide are similar for the treatment of ESD-induced ulcers. In large-sized ulcers, esomeprazole plus rebamipide promotes ulcer healing.

Abstract
Gastric endoscopic submucosal dissection (ESD) causes artificial gastric ulcers and there is no consensus regarding the optimal perioperative management in terms of prevention of intra- or postoperative bleeding and promotion of healing. Traditionally, 8-week administration of proton pump inhibitors (PPI) and mucosal protective agents were used in the same way as for peptic ulcer management. However, recent studies have revealed that prior use of PPI might reduce intraoperative bleeding or early-phase postoperative bleeding, and combination of histamine-2 receptor antagonist (H2RA), and second-look endoscopy might have a similar effect on postoperative bleeding to PPI. Additionally, the advantage of PPI over H2RA is not proven and the optimal duration of PPI may be shortened until 2 weeks when the deteriorating factors for ESD ulcer are excluded. Furthermore, mucosal protective agents may facilitate ulcer healing. Further studies are needed to determine the optimal treatment protocol before and after ESD for both prevention of bleeding complication and promotion of ulcer healing, by using available antisecretory agents and mucosal protective agents.

Abstract
Endoscopic submucosal dissection (ESD) is a novel endoscopic procedure first developed in the 1990s which enables en bloc resection of gastric neoplastic lesions that are difficult to resect via conventional endoscopic mucosal resection. However, given that ESD increases the risk of intra- and post-ESD delayed bleeding and that platelet aggregation and coagulation in artificial ulcers after ESD strongly depend on intragastric pH, faster and stronger acid inhibition via proton pump inhibitors (PPIs) and histamine 2-receptor antagonists (H(2)RAs) as well as endoscopic hemostasis by thermocoagulation during ESD have been used to prevent ESD-related bleeding. Because PPIs more potently inhibit acid secretion than H(2)RAs, they are often the first-line drugs employed in ESD treatment. However, acid inhibition after the initial infusion of a PPI is weaker in the early phase than that achievable with H(2)RAs; further, PPI effectiveness can vary depending on genetic differences in CYP2C19. Therefore, optimal acid inhibition may require tailored treatment based on CYP2C19 genotype when ESD is performed, with a concomitant infusion of PPI and H(2)RA possibly most effective for patients with the rapid metabolizer CYP2C19 genotype, while PPI alone may be sufficient for those with the intermediate or poor metabolizer genotypes.
