Clin Gastroenterol Hepatol 2023; 21:2844-2853.e5. [PMID: 36906081 DOI: 10.1016/j.cgh.2023.02.031] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 02/17/2023] [Accepted: 02/28/2023] [Indexed: 03/13/2023]
Abstract
BACKGROUND & AIMS Hemostatic powders have been clinically used in the treatment of gastrointestinal bleeding. We investigated the non-inferiority of a polysaccharide hemostatic powder (PHP), compared with conventional endoscopic treatments, for peptic ulcer bleeding (PUB). METHODS This study was a prospective multi-center, randomized, open-label, controlled trial at 4 referral institutions. We consecutively enrolled patients who had undergone emergency endoscopy for PUB. The patients were randomly assigned to either a PHP or conventional treatment group. In the PHP group, diluted epinephrine was injected, and the powder was applied as a spray. Conventional endoscopic treatment included the use of electrical coagulation or hemoclipping after injection of diluted epinephrine. RESULTS Between July 2017 and May 2021, 216 patients were enrolled in this study (PHP group, 105; control group, 111). Initial hemostasis was achieved in 92 of 105 patients (87.6%) in the PHP group and 96 of 111 patients (86.5%) in the conventional treatment group. Re-bleeding did not differ between the 2 groups. In subgroup analysis, the initial hemostasis failure rate in the conventional treatment group was 13.6% for Forrest IIa cases; however, there was no initial hemostasis failure in the PHP group (P = .023). Large ulcer size (≥15 mm) and chronic kidney disease with dialysis were independent risk factors for re-bleeding at 30 days. No adverse events were associated with PHP use. CONCLUSIONS PHP is not inferior to conventional treatments and could be useful in initial endoscopic treatment for PUB. Further studies are needed to confirm the re-bleeding rate of PHP.

Schmitz D, Thielemann L, Grassmann F. Bipolar haemostatic forceps versus standard therapy by haemoclip + / - epinephrine injection as initial endoscopic treatment in active non-variceal upper GI bleeding: study protocol for a prospective, randomized multicentre trial (BeBop-Trial). Trials 2023; 24:407. [PMID: 37322511 PMCID: PMC10268387 DOI: 10.1186/s13063-023-07394-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Accepted: 05/18/2023] [Indexed: 06/17/2023] Open
Abstract
BACKGROUND Patients with active nonvariceal upper gastrointestinal bleeding (NVUGIB) usually require urgent endoscopic treatment. Standard therapy (ST) using haemoclip + / - epinephrine injection is not always successful. Bipolar haemostatic forceps (HemoStat/Pentax®) are an approved medical device for the treatment of gastrointestinal bleeding. However, their use as a primary endoscopic treatment for active NVUGIB has not yet been proven in a randomized prospective study. METHODS This is a prospective, randomized, multicentre superiority trial (n ≥ 5). Patients with active NVUGIB will be randomized (1:1) to ST and to experimental therapy (ET) by application of bipolar haemostatic forceps. In the case of failed initial treatment within 15 min, crossover treatment will be attempted first. Rescue treatment (e.g. via over-the-scope-clip) will then be allowed after 30 min. All patients will also receive standard therapy with proton pump inhibitors. Forty-five patients per treatment arm are required to demonstrate an absolute difference of 25.4% with a power of 80% and a significance level of 0.05. DISCUSSION The hypothesis of the study is that bipolar haemostatic forceps are superior to ST in terms of successful primary haemostasis and the absence of recurrent bleeding within 30 days (combined endpoint). The 1:1 randomization is also ethically justifiable for this study, as both procedures are approved for the intervention in question. To further increase the safety of the patients in the study, crossover treatment and rescue treatment are planned. The prospective design seems feasible in a reasonable time frame (recruitment period of 12 months), as nonvariceal upper gastrointestinal bleeding is common. Anticoagulants and/or antiplatelet drugs could be an important confounding factor in the statistical analysis that needs to be taken into account and calculated if necessary. In conclusion, this randomized, prospective, multicentre study could make an important contribution to answering the question of whether bipolar haemostatic forceps could be the first-line therapy in the endoscopic treatment of stage Forrest I a + b NVUGIB. TRIAL REGISTRATION ClinicalTrials.gov NCT05353062. Registered on April 30 2022.

Abstract
Gastroduodenal peptic ulcers are the main cause of nonvariceal upper gastrointestinal bleeding (UGIB). We believe that recent advances in endoscopic techniques and devices for diagnosing upper gastrointestinal tract tumors have advanced hemostasis for UGIB. However, few prospective multicenter studies have examined how these changes affect the prognosis. This prospective study included 246 patients with gastroduodenal peptic ulcers treated at 14 participating facilities. The primary endpoint was in-hospital mortality within 4 weeks, and the secondary endpoints required intervention and refractory bleeding. Subsequently, risk factors affecting these outcomes were examined using various clinical items. Furthermore, the usefulness of the risk stratification using the Glasgow-Blatchford score, rockall score and AIMS65 based on data from the day of the first urgent endoscopy were examined in 205 cases in which all items were complete there are two periods. Thirteen (5%) patients died within 4 weeks; and only 2 died from bleeding. Significant risk factors for poor outcomes were older age and severe comorbidities. Hemostasis was required in 177 (72%) cases, with 20 cases of refractory bleeding (2 due to unsuccessful endoscopic treatment and 18 due to rebleeding). Soft coagulation was the first choice for endoscopic hemostasis in 57% of the cases and was selected in more than 70% of the cases where combined use was required. Rockall score and AIMS65 predicted mortality equally, and Glasgow-Blatchford score was the most useful in predicting the requirement for intervention. All scores predicted refractory bleeding similarly. Although endoscopic hemostasis for UGIB due to peptic ulcer had a favorable outcome, old age and severe comorbidities were risk factors for poor prognosis. We recommend that patients with UGIB should undergo early risk stratification using a risk scoring system.

Safety and Efficacy of Sedation During Emergency Endoscopy for Upper Gastrointestinal Bleeding: A Propensity Score Matching Analysis. Dig Dis Sci 2022; 68:1426-1434. [PMID: 36272038 PMCID: PMC10102050 DOI: 10.1007/s10620-022-07740-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Accepted: 10/13/2022] [Indexed: 12/09/2022]
Abstract
BACKGROUND AND AIM This study aimed to compare patients with and without sedation during emergency endoscopy for upper gastrointestinal bleeding (UGIB) and to clarify the safety and efficacy of sedation in emergency endoscopy. METHODS We retrospectively collected 389 patients who underwent emergency endoscopy for UGIB at Ureshino Medical Center from 2016 to 2021. Patients were divided into two groups: sedation group during emergency endoscopy and nonsedation group. Clinical characteristics, patient status on admission, and UGIB etiology were evaluated. Treatment outcomes and adverse events were evaluated using propensity score matching (PSM), and risk factors for mortality from UGIB were investigated using Cox multivariate analysis. RESULTS The sedation group was significantly younger, composed of a higher proportion of males, and had chronic liver disease. Blood pressure and hemoglobin level on admission were significantly higher in the sedation group. The main cause of bleeding was peptic ulcer, which was significantly higher in the nonsedation group. PSM created 133 matched pairs. The success rate of endoscopic hemostasis was similar in both groups, and procedure time was significantly shorter in the sedation group than in the nonsedation group (17.6 ± 10.0 versus 20.2 ± 10.2 min, P = 0.04). There were no significant differences in adverse events between groups. Cox multivariate analyses revealed that red blood cell transfusion [hazard ratio (HR) 4.45, P < 0.02] and rebleeding (HR 3.30, P = 0.03) were associated with increased risk of 30-day mortality from UGIB. CONCLUSIONS Sedation reduced the procedure time during emergency endoscopy for UGIB. Sedation during emergency endoscopy for UGIB is acceptable for safe endoscopic procedures.

Abstract
AbstractNonvariceal upper gastrointestinal hemorrhage (NVUGIH) is a common GI emergency with significant morbidity and mortality. Triaging cases on the basis of patient-related factors, restrictive blood transfusion strategy, and hemodynamic stabilization are key initial steps for the management of patients with NVUGIH. Endoscopy remains a vital step for both diagnosis and definitive management. Multiple studies and guidelines have now defined the optimum timing for performing the endoscopy after hospitalization, to better the outcome. Conventional methods for achieving endoscopic hemostasis, such as injection therapy, contact, and noncontact thermal therapy, and mechanical therapy, such as through-the-scope clips, have reported to have 76 to 90% efficacy for primary hemostasis. Newer modalities to enhance hemostasis rates have come in vogue. Many of these modalities, such as cap-mounted clips, coagulation forceps, and hemostatic powders have proved to be efficacious in multiple studies. Thus, the newer modalities are recommended not only for management of persistent bleed and recurrent bleed after failed initial hemostasis, using conventional modalities but also now being advocated for primary hemostasis. Failure of endotherapy would warrant radiological or surgical intervention. Some newer tools to optimize endotherapy, such as endoscopic Doppler probes, for determining flow in visible or underlying vessels in ulcer bleed are now being evaluated. This review is focused on the technical aspects and efficacy of various endoscopic modalities, both conventional and new. A synopsis of the various studies describing and comparing the modalities have been outlined. Postendoscopic management including Helicobacter pylori therapy and starting of anticoagulants and antiplatelets have also been outlined.

Safety and Efficacy of the Noncessation Method of Antithrombotic Agents after Emergency Endoscopic Hemostasis in Patients with Nonvariceal Upper Gastrointestinal Bleeding: A Multicenter Pilot Study. Can J Gastroenterol Hepatol 2021; 2021:6672440.

Abstract
BACKGROUND AND AIMS The present study aimed to clarify the safety and efficacy of the noncessation method of antithrombotic agents after emergency endoscopic hemostasis in patients with nonvariceal upper gastrointestinal bleeding (UGIB). METHODS In this multicenter, prospective, pilot study, we performed emergency endoscopic hemostasis for nonvariceal UGIB in patients taking antithrombotic agents and resumed the medications without a cessation period (group A). The clinical characteristics, types of antithrombotic agents, UGIB etiology, treatment outcome, and adverse events were evaluated. We used propensity score matching to compare treatment outcomes and adverse events with our previous cohort (group B) in whom antithrombotic agents were transiently discontinued after emergency endoscopic hemostasis. RESULTS Forty-three consecutive patients were prospectively enrolled. The main antithrombotic agents were low-dose aspirin and direct oral anticoagulants; 11 patients (25.6%) were taking multiple antithrombotics. Peptic ulcers were the main cause of bleeding (95.4%). Endoscopic hemostasis was successful in all patients and the incidence of rebleeding within a month was 7.0%. Propensity score matching created 40 matched pairs. Endoscopic hemostasis was performed by soft coagulation significantly more frequently in group A than in group B (97.5% versus 60.0%, P < 0.001). Neither the rebleeding rate within a month nor thromboembolic event rate was different between the two groups. However, the mean duration of hospitalization was significantly shorter in group A than in group B (8.6 ± 5.2 d versus 14.4 ± 7.1 d, P < 0.001). CONCLUSIONS Antithrombotic agents possibly can be continued after successful emergency endoscopic hemostasis for nonvariceal UGIB.

Abstract
We performed systematic reviews addressing predefined clinical questions to develop recommendations with the GRADE approach regarding management of patients with overt upper gastrointestinal bleeding. We suggest risk assessment in the emergency department to identify very-low-risk patients (e.g., Glasgow-Blatchford score = 0-1) who may be discharged with outpatient follow-up. For patients hospitalized with upper gastrointestinal bleeding, we suggest red blood cell transfusion at a threshold of 7 g/dL. Erythromycin infusion is suggested before endoscopy, and endoscopy is suggested within 24 hours after presentation. Endoscopic therapy is recommended for ulcers with active spurting or oozing and for nonbleeding visible vessels. Endoscopic therapy with bipolar electrocoagulation, heater probe, and absolute ethanol injection is recommended, and low- to very-low-quality evidence also supports clips, argon plasma coagulation, and soft monopolar electrocoagulation; hemostatic powder spray TC-325 is suggested for actively bleeding ulcers and over-the-scope clips for recurrent ulcer bleeding after previous successful hemostasis. After endoscopic hemostasis, high-dose proton pump inhibitor therapy is recommended continuously or intermittently for 3 days, followed by twice-daily oral proton pump inhibitor for the first 2 weeks of therapy after endoscopy. Repeat endoscopy is suggested for recurrent bleeding, and if endoscopic therapy fails, transcatheter embolization is suggested.

Abstract
1: ESGE recommends in patients with acute upper gastrointestinal hemorrhage (UGIH) the use of the Glasgow-Blatchford Score (GBS) for pre-endoscopy risk stratification. Patients with GBS ≤ 1 are at very low risk of rebleeding, mortality within 30 days, or needing hospital-based intervention and can be safely managed as outpatients with outpatient endoscopy.Strong recommendation, moderate quality evidence. 2: ESGE recommends that in patients with acute UGIH who are taking low-dose aspirin as monotherapy for secondary cardiovascular prophylaxis, aspirin should not be interrupted. If for any reason it is interrupted, aspirin should be re-started as soon as possible, preferably within 3-5 days.Strong recommendation, moderate quality evidence. 3: ESGE recommends that following hemodynamic resuscitation, early (≤ 24 hours) upper gastrointestinal (GI) endoscopy should be performed. Strong recommendation, high quality evidence. 4: ESGE does not recommend urgent (≤ 12 hours) upper GI endoscopy since as compared to early endoscopy, patient outcomes are not improved. Strong recommendation, high quality evidence. 5: ESGE recommends for patients with actively bleeding ulcers (FIa, FIb), combination therapy using epinephrine injection plus a second hemostasis modality (contact thermal or mechanical therapy). Strong recommendation, high quality evidence. 6: ESGE recommends for patients with an ulcer with a nonbleeding visible vessel (FIIa), contact or noncontact thermal therapy, mechanical therapy, or injection of a sclerosing agent, each as monotherapy or in combination with epinephrine injection. Strong recommendation, high quality evidence. 7 : ESGE suggests that in patients with persistent bleeding refractory to standard hemostasis modalities, the use of a topical hemostatic spray/powder or cap-mounted clip should be considered. Weak recommendation, low quality evidence. 8: ESGE recommends that for patients with clinical evidence of recurrent peptic ulcer hemorrhage, use of a cap-mounted clip should be considered. In the case of failure of this second attempt at endoscopic hemostasis, transcatheter angiographic embolization (TAE) should be considered. Surgery is indicated when TAE is not locally available or after failed TAE. Strong recommendation, moderate quality evidence. 9: ESGE recommends high dose proton pump inhibitor (PPI) therapy for patients who receive endoscopic hemostasis and for patients with FIIb ulcer stigmata (adherent clot) not treated endoscopically. (A): PPI therapy should be administered as an intravenous bolus followed by continuous infusion (e. g., 80 mg then 8 mg/hour) for 72 hours post endoscopy. (B): High dose PPI therapies given as intravenous bolus dosing (twice-daily) or in oral formulation (twice-daily) can be considered as alternative regimens.Strong recommendation, high quality evidence. 10: ESGE recommends that in patients who require ongoing anticoagulation therapy following acute NVUGIH (e. g., peptic ulcer hemorrhage), anticoagulation should be resumed as soon as the bleeding has been controlled, preferably within or soon after 7 days of the bleeding event, based on thromboembolic risk. The rapid onset of action of direct oral anticoagulants (DOACS), as compared to vitamin K antagonists (VKAs), must be considered in this context.Strong recommendation, low quality evidence.

Abstract
Monopolar hemostatic forceps with soft coagulation (MHFSC) have been compared with hemoclips, heater probe, and argon plasma coagulation (APC) for the treatment of peptic ulcer bleeding. In this systematic review and meta-analysis, we compared MHFSC with other modalities in the treatment of peptic ulcer bleeding. We reviewed MEDLINE, Embase, Scopus, Cochrane, Web of Science, and Scopus from inception to 7 January 2019 to identify studies comparing MHFSC with other modalities for peptic ulcer bleeding. The primary outcome of interest was achievement of initial hemostasis. Secondary outcomes were rebleeding, adverse events, procedure time, and length of hospital stay. Data were analyzed using a random effects model and summarized as pooled odds ratio (OR) with 95% confidence interval (CI). Heterogeneity was assessed by I statistic. We included five randomized controlled trials and one observational study comprising 693 patients with endoscopically confirmed actively bleeding ulcers (spurting or oozing) or nonbleeding visible vessel. MHFSC was superior to other modalities in achieving initial hemostasis (OR 0.25; 95% CI 0.08-0.81; I = 67%) and prevention of rebleeding (OR 0.28; 95% CI 0.09-0.86; I = 46%). Rates of adverse events were similar between MHFSC and other modalities. Procedure times were shorter with MHFSC (mean difference -4.15 min; 95% CI -4.83 to -3.47; I= 59%). Length of hospital stay was also shorter with MHFSC. MHFSC appears to be more effective than other modalities for achievement of initial hemostasis and reduction of rebleeding among patients with peptic ulcer bleeding.

Abstract
Upper gastrointestinal bleeding is defined as the bleeding originating from the esophagus to the ligament of Treitz and further classified into variceal and non-variceal gastrointestinal bleeding. Non-variceal upper gastrointestinal bleeding remains a common clinical problem globally. It is associated with high mortality, morbidity, and cost of the health care system. Despite the continuous improvement of therapeutic endoscopy, the 30-d readmission rate secondary to rebleeding and associated mortality is an ongoing issue. Available Food and Drug Administration approved traditional or conventional therapeutic endoscopic modalities includes epinephrine injection, argon plasma coagulation, heater probe, and placement of through the scope clip, which can be used alone or in combination to decrease the risk of rebleeding. Recently, more attention has been paid to the novel advanced endoscopic devices for primary treatment of the bleeding lesion and as a secondary measure when conventional therapies fail to achieve hemostasis. This review highlights emerging endoscopic modalities used in the management of non-variceal upper gastrointestinal related bleeding such as over-the-scope clip, Coagrasper, hemostatic sprays, radiofrequency ablation, cryotherapy, endoscopic suturing devices, and endoscopic ultrasound-guided angiotherapy. In this review article, we will also discuss the technical aspects of the common procedures, outcomes in terms of safety and efficacy, and their advantages and limitations in the setting of non-variceal upper gastrointestinal bleeding.

World J Gastroenterol 2019; 25:6342-6353. [PMID: 31754294 PMCID: PMC6861850 DOI: 10.3748/wjg.v25.i42.6342] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2019] [Revised: 09/11/2019] [Accepted: 11/01/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The two main causes of gastric ulcer bleeding are Helicobacter pylori (H. pylori) infection and ulcerogenic medicines, although the number of cases caused by each may vary with age. In Japan, the rate of H. pylori infection has fallen over the last decade and the number of prescriptions for non-steroidal anti-inflammatory drugs (NSAIDs) and antithrombotic drugs is increasing as the population ages. Methods of treatment for gastric ulcer bleeding have advanced with the advent of hemostatic forceps and potassium-competitive acid blocker (P-CAB). Thus, causes and treatments for gastric ulcer bleeding have changed over the last decade.
AIM To examine the trends of gastric ulcer bleeding over 10 years in the metropolitan area of Japan.
METHODS This is a single-center retrospective study. A total of 564 patients were enrolled from inpatients admitted to our hospital with gastric ulcer bleeding between 2006 and 2016. Age, medication history, H. pylori infection, method of treatment, rate of rebleeding, and the length of hospitalization were analyzed. Factors associated with gastric ulcer bleeding were evaluated using Fisher’s exact test, Pearson’s Chi-squared test or Student’s t-test as appropriate. The Jonckheere-Terpstra test was used to evaluate trends. A per-protocol analysis was used to examine the rate of H. pylori infection.
RESULTS There was a significant increase in the mean age over time (P < 0.01). The rate of H. pylori infection tended to decrease over the study period (P = 0.10), whereas the proportion of patients taking antithrombotic agents or NSAIDs tended to increase (P = 0.07). Over time, the use of NSAIDs and antithrombotic drugs increased with age. By contrast, the rate of H. pylori infection during the study period fell with age. H. pylori-induced ulcers accounted for the majority of cases in younger patients (< 70 years old); however, the rate decreased with age (P < 0.01). The method of treatment trend has changed significantly over time. The main method of endoscopic hemostasis has changed from clipping and injection to forceps coagulation (P < 0.01), and frequently prescribed medicines have changed from proton pump inhibitor to P-CAB (P < 0.01). The rate of rebleeding during the latter half of the study was significantly lower than that in the first half.
CONCLUSION These trends, gastric ulcers caused by ulcerogenic drugs were increasing with age and H. pylori-induced ulcers were more common in younger patients, were observed.

Analyses of the Temperature Field of a Piezoelectric Micro Actuator in the Endoscopic Biopsy Channel. APPLIED SCIENCES-BASEL 2019.

Abstract
Micro actuators have been used to realize the arrival of digestive tract lesions for the local targeted application of drugs in endoscopes. However, there still exists a key safety issue that casts a shadow over the practical and safe implementation of actuators in the human body, namely an overheated environment caused by actuators’ operation. Herein, with the aim of solving the temperature rising problem of a piezoelectric micro actuator operating in an endoscopic biopsy channel (OLYMPUS, Tokyo, Japan), a thermal finite element method (FEM) based on COMSOL Multiphysics software is proposed. The temperature distribution and its rising curves are obtained by the FEM method. Both the simulated and experimental maximum temperatures are larger than the safety value (e.g., 42 °C for human tissues) when the driving voltage of the actuator is 200 Vpp, which proves that the overheating problem really exists in the actuator. Furthermore, the results show that the calculated temperature rising curves correspond to the experimental results, proving the effectiveness of this FEM method. Therefore, we introduce a temperature control method through optimizing the duty ratio of the actuator. In comparison with a 100% duty ratio operation condition, it is found that a 60% duty ratio with a driving voltage of 200 Vpp can more effectively prevent the temperature rising issue in the first 3 min, as revealed by the corresponding temperatures of 44.4 and 41.4 °C, respectively. When the duty ratio is adjusted to 30% or less, the temperature rise of the actuator can be significantly reduced to only 36.6 °C, which is close to the initial temperature (36.4 °C). Meanwhile, the speed of the actuator can be well-maintained at a certain level, demonstrating its great applicability for safe operation in the human body.

Abstract
Non-variceal upper gastrointestinal bleeding (NVUGIB) refers to blood loss from the gastrointestinal tract proximal to the ligament of Treitz due to lesions that are non-variceal in origin. The distinction of the bleeding source as non-variceal is important in numerous aspects, but none more so than endoscopic approaches for successful hemostasis. When a patient presents with acute overt blood loss, NVUGIB is a medical emergency, which requires immediate intervention. There have been major strides in pharmacologic and endoscopic interventions for successful induction and remission of hemostasis in the last two decades. Despite achieving tangible improvements, the burden of the disease and the consequent mortality remain high. To address endoscopic outcomes better, several new technologies have emerged and have been subsequently incorporated to the armamentarium of hemostatic tools. This study aims to provide a succinct review on novel technologies for endoscopic hemostasis.

Abstract
BACKGROUND AND AIMS Although various methods are used in the treatment of peptic ulcer bleeding, there is not a standard recommended approach. The choice depends on multiple factors such as location of the ulcer, clinical experience of the endoscopist, and local facilities of the clinic. We aimed to compare the efficacy of monopolar hemostatic forceps soft coagulation (MHFSC) and hemoclips (HCs) in the treatment of peptic ulcer-related upper GI bleeding. METHODS The study group included patients who had GI bleeding due to Forrest 1a, 1b, and 2a gastric or duodenal ulcers within 1 year. Patients with bleeding diathesis, history of gastrectomy, pregnancy, or younger than age 18 years were excluded. The remaining were randomized to MHFSC and HC treatment groups and compared in terms of clinical and endoscopic features, initial hemostasis success rates, recurrent bleeding rates within the first 7 days, time to achieve hemostasis, length of hospitalization stay, and adverse events. RESULTS One hundred twelve patients were randomized to MHFSC (n = 56) and HC (n = 56) groups. There was no statistically significant difference between the groups with respect to demographic features, medications, underlying chronic diseases, location, and Forrest classification of the ulcers. The initial hemostasis success rate was 98.2% (55/56) in the MHFSC group and 80.4% (45/56) in the HC group (P = .004). Recurrent bleeding was detected in 2 patients in the MHFSC group (3.6%) and 8 patients in the HC group (17.7%; P = .04). The duration of endoscopic procedures (302 ± 87.8 vs 568 ± 140.4 seconds) and the length of hospital stay (3.50 ± 1.03 vs 4.37 ± 1.86 days) were significantly shorter in the MHFSC group. There were no adverse events in either group. CONCLUSIONS MHFSC is more effective in achieving initial hemostasis compared with HCs in the treatment of peptic ulcer bleeding and provides a shorter procedure time and a lower recurrent bleeding rate.

Abstract
BACKGROUND The aim of the present study was to determine differences in the prognosis of patients in Japan who underwent emergency endoscopic hemostasis (i) during regular hours versus off hours and (ii) as outpatients versus hospitalized patients. METHODS The present retrospective study included 443 patients who underwent emergency endoscopic hemostasis for non-variceal upper gastrointestinal bleeding from January 2008 to December 2014. These patients were classified into 2 groups: hospitalized patients and outpatients. The outpatients were further subclassified into those who visited the hospital during regular hours and those who visited during off hours. RESULTS The outcomes of outpatients who underwent emergency hemostasis during off hours did not differ from patients treated during regular hours. Multivariate analysis revealed that outcomes of hospitalized patients, including mortality, need for blood transfusion and length of hospitalization, were worse than those of outpatients; it also revealed that patient age, malnutrition rate and prevalence of diabetes and neoplasms were higher among hospitalized patients than those in outpatients. CONCLUSIONS The clinical outcomes of patients who underwent emergency endoscopic hemostasis for upper gastrointestinal bleeding during off hours did not differ from those of patients treated during regular hours. Outcomes were worse among hospitalized patients, mainly because of their bad general condition.

Abstract
BACKGROUND/AIMS In this study, investigations were carried out to ascertain whether soft coagulation hemostasis for non-variceal upper gastrointestinal bleeding (UGIB) has ever been performed in a time-dependent manner. METHODS Medical records of 502 patients who had undergone emergency endoscopic hemostasis for non-variceal UGIB from 2003 to 2014 were checked and the modalities were used to achieve hemostasis compared between the first period from 2003 to 2008 (197 patients) and the second period from 2009 to 2014 (305 patients). RESULTS Endoscopic hemostasis was successfully achieved in 96.0% of study patients. Peptic ulcers were the main cause of bleeding (89.4%). Endoscopic hemostasis was performed by soft coagulation significantly more frequently during the second (71.1%) than the first period (11.7%; p < 0.001). Endoscopic hemostasis was mainly achieved by trainees during the second period (76.1%); these trainees comprised a significantly greater proportion of endoscopists than during the first period (56.3%; p < 0.001). Endoscopic-related complications did not differ between the 2 periods. The only risk factor for rebleeding after hemostasis was Helicobacter pylori infection; the use of soft coagulation and the fact that endoscopists were just trainees were not risk factors. CONCLUSION Our findings suggest that using soft coagulation to achieve endoscopic hemostasis for non-variceal UGIB is safe and effective, even when it is performed by trainees.

Abstract
Japan Gastroenterological Endoscopy Society (JGES) has compiled a set of guidelines for endoscopic management of non-variceal upper gastrointestinal bleeding using evidence-based methods. The major cause of non-variceal upper gastrointestinal bleeding is peptic gastroduodenal ulcer bleeding. As a result, these guidelines mainly focus on peptic gastroduodenal ulcer bleeding, although bleeding from other causes is also overviewed. From the epidemiological aspect, in recent years in Japan, bleeding from drug-related ulcers has become predominant in comparison with bleeding from Helicobacter pylori (HP)-related ulcers, owing to an increase in the aging population and coverage of HP eradication therapy by national health insurance. As for treatment, endoscopic hemostasis, in which there are a variety of methods, is considered to be the first-line treatment for bleeding from almost all causes. It is very important to precisely evaluate the severity of the patient's condition and stabilize the patient's vital signs with intensive care for successful endoscopic hemostasis. Additionally, use of antisecretory agents is recommended to prevent rebleeding after endoscopic hemostasis, especially for gastroduodenal ulcer bleeding. Eighteen statements with evidence and recommendation levels have been made by the JGES committee of these guidelines according to evidence obtained from clinical research studies. However, some of the statements that are supported by a low level of evidence must be confirmed by further clinical research.

Abstract
BACKGROUND Peptic ulcer represents the most common cause of upper gastrointestinal bleeding. Endoscopic therapy can reduce the risks of rebleeding, continued bleeding, need for surgery, and mortality. The objective of this review is to compare the different modalities of endoscopic therapy. METHODS Studies were identified by searching electronic databases MEDLINE, Embase, Cochrane, LILACS, DARE, and CINAHL. We selected randomized clinical trials that assessed contemporary endoscopic hemostatic techniques. The outcomes evaluated were: initial hemostasis, rebleeding rate, need for surgery, and mortality. The possibility of publication bias was evaluated by funnel plots. An additional analysis was made, including only the higher-quality trials. RESULTS Twenty-eight trials involving 2988 patients were evaluated. Injection therapy alone was inferior to injection therapy with hemoclip and with thermal coagulation when evaluating rebleeding and the need for emergency surgery. Hemoclip was superior to injection therapy in terms of rebleeding; there were no statistically significant differences between hemoclip alone and hemoclip with injection therapy. There was considerable heterogeneity in the comparisons between hemoclip and thermal coagulation. There were no statistically significant differences between thermal coagulation and injection therapy, though their combination was superior, in terms of rebleeding, to thermal coagulation alone. CONCLUSIONS Injection therapy should not be used alone. Hemoclip is superior to injection therapy, and combining hemoclip with an injectate does not improve hemostatic efficacy above hemoclip alone. Thermal coagulation has similar efficacy as injection therapy; combining these appears to be superior to thermal coagulation alone. Therefore, we recommend the application of hemoclips or the combined use of injection therapy with thermal coagulation for the treatment of peptic ulcer bleeding.

BACKGROUND AND AIM Endoscopic therapy has been demonstrated to be effective in achieving hemostasis for bleeding peptic ulcers. Thermal coagulation is one of the most commonly used methods, with a high success rate. Recently, endoscopic submucosal dissection for early gastric carcinoma was developed and hemostasis with soft coagulation using hemostatic forceps was introduced. The aim of this study was to compare the hemostatic efficacy of soft coagulation with heater probe thermocoagulation for peptic ulcer bleeding. METHODS Patients who visited our hospital with hematemesis or melena underwent emergency endoscopy. Inclusion criteria were presentation with an actively bleeding ulcer, a nonbleeding visible vessel, or an adherent clot. Patients were excluded if they were unwilling to give written informed consent or had a bleeding gastric malignancy. Patients were randomized to receive endoscopic hemostasis with soft coagulation (Group S) or heater probe thermocoagulation (Group H). The primary endpoint was the primary hemostasis rate and secondary endpoints were rebleeding rate, complications, and the procedure time. RESULTS Between May 2010 and February 2012, a total of 111 patients (89 gastric ulcers and 22 duodenal ulcers) were enrolled. Primary hemostasis was achieved in 54 patients (96%) in Group S and 37 (67%) in Group H (P<0.0001). Rebleeding occurred in 7 patients in Group H and none in Group S. Of these 7 patients, urgent surgery was performed in 1. Perforation occurred in 2 patients in Group H, which was managed conservatively. CONCLUSIONS For patients with gastroduodenal ulcer bleeding, soft coagulation using monopolar hemostatic forceps is more effective than heater probe thermocoagulation for achieving hemostasis.

Abstract
Endoscopic treatment has been accepted as first-line treatment of upper gastrointestinal bleeding, both for variceal as well as for non-variceal haemorrhage. Dual modality treatment including injection therapy with mechanical or thermal haemostatic techniques has shown superior outcome compared with injection monotherapy in non-variceal bleeding. During recent years, new endoscopic devices have been developed and existing endoscopic techniques have been adapted to facilitate primary control of bleeding or achieve haemostasis in refractory haemorrhage. For mechanical haemostasis, larger, rotatable and repositionable clips have been developed; multiple-preloaded clips are also available now. Over the scope clips allow to ligate larger vessels and can close ulcer defects up to 20 mm. Topical, easily applied substances withdraw fluid from the blood and thereby initiate blood clotting. This can be helpful in diffuse oozing bleeding, for example, from tumour or hypertensive gastropathy and has also shown promising results in variceal and arterial bleeding as bridging before definitive treatment is available. Radiofrequency ablation and multiband ligation have emerged as new tools in the endoscopic management of gastric antral vascular ectasia. In acute refractory variceal bleeding, a covered and removable oesophagus stent can provide tamponade and gain time for transport to an interventional endoscopic centre or for radiological intervention such as TIPS.

Abstract
BACKGROUND AND AIMS We aimed to study the feasibility of endoscopic submucosal dissection (ESD) for the removal of gastric muscularis propria tumors and to evaluate the efficacy and safety of ESD for this treatment. METHODS Eighteen patients with gastric SMTs originating from the muscularis propria were treated by ESD between July 2008 and July 2011. Tumor characteristics, complications, en bloc resection rate, and local recurrence rate were evaluated. RESULTS Among the 18 patients, 11 were women (61.1 %). The median age was 65.3 ± 6.3 years old (range 30-71 years old). Seventeen tumors were resected completely by ESD (success rate 94.4 %). The mean tumor size as determined by endoscopic ultrasound was 2.6 ± 1.2 cm (range 1.0-3.5 cm). The histological diagnosis was gastrointestinal stromal tumor for 13 lesions and leiomyoma for four tumors. The mean operation time was 90 ± 38 min (range 50-120 min), and the average blood loss was 20 ml. Two patients developed perforation, which was closed by endoscopic methods with metallic clips. The tumor was closely adhered to the muscularis propria and was convex to the enterocoelia in one case. No single case had severe complications, such as GI bleeding, peritonitis, or abdominal abscess, and there were no other immediate post-procedure complications. CONCLUSIONS ESD is a safe, effective, well-tolerated, and minimally invasive therapy for the intraluminal SMTs originating from gastric muscularis propria with relatively few complications. Although there is a risk of perforation which has become manageable endoscopically.

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

Abstract
BACKGROUND AND AIM There are few clinical studies on the risk factors for rebleeding based on the endoscopic hemostatic procedure carried out, including ulcer characteristics such as exposed blood vessels. The present study aims to clarify the risk factors for rebleeding after endoscopic clipping hemostasis for hemorrhagic gastroduodenal ulcers. METHODS A retrospective study was carried out with data collected during the 10-year period from January 2000 to December 2009 for 312 consecutive patients with hemorrhagic gastroduodenal ulcer. Two hundred and ninety-three patients (216 men and 77 women; mean age, 67.0 ± 15.0 years) who underwent endoscopic clipping as the initial hemostatic treatment were analyzed. The risk factors for rebleeding were determined by comparing 271 patients who did not rebleed after initial treatment with 22 patients who developed rebleeding. RESULTS The success rate of initial clipping hemostasis was 100%; however, rebleeding occurred in 7.5% (22/293) and a multivariate analysis identified exposed blood vessels of more than 2 mm in diameter as independent risk factors for rebleeding (P = 0.0124, odds ratio 6.25 [95% CI: 1.53-13.62]). CONCLUSIONS Endoscopic clipping monotherapy is effective for hemorrhagic gastroduodenal ulcers; however, exposed blood vessels of more than 2 mm in diameter in the initial endoscopic procedure are a risk factor for rebleeding.

Abstract
BACKGROUND The incidence of delayed bleeding after endoscopic submucosal dissection (ESD) for gastric neoplasms is reported to be approximately 5 %. We examined whether postprocedural combined treatment using the coagulation plus artery-selective clipping (2C) method is a useful measure for preventing delayed bleeding after ESD. METHODS A total of 234 gastric epithelial neoplasms were treated from June 2007 to May 2012. Post-ESD coagulation (PEC) and clipping for part of the vessels was performed for 154 lesions from June 2007 to June 2010. A total of 80 lesions were treated using the 2C method from July 2010 to May 2012. During ESD, the locations of the arteries were recorded on a schematic diagram of the lesion. Arteries were defined as regions of arterial bleeding that required coagulation or apparent arteries in which preventive coagulation was performed. When ESD was completed, soft coagulation was performed for arteries in the resection area using hemostatic forceps, followed by arterial clipping for additional strength. Coagulation also was performed continuously for visible vessels in the resection area. This was a retrospective study. The incidence rates of delayed bleeding after ESD, as evidenced by hematemesis or melena, or the presence of anemia (decline in Hb >2 g/dl) that required emergency endoscopy were recorded. RESULTS Delayed bleeding occurred in 7 (4.5 %) of the 154 cases treated using PEC and in 1 (1.3 %) of the 80 cases treated using the 2C method. The mean time required for the 2C method was 15.0 ± 7.0 min (range, 5-44 min). The mean number of clippings per lesion was 3.8 ± 2.8 (range, 0-13). Almost all clips fell off within 2 months of the procedure. CONCLUSIONS Coagulation plus artery-selective clipping (the 2C method) of post-ESD ulcers might effectively reduce the incidence of delayed bleeding after ESD for gastric neoplasms.

Abstract
Endoscopic submucosal dissection (ESD) is now the most common endoscopic treatment in Japan for intramucosal gastrointestinal neoplasms (non-metastatic). ESD is an invasive endoscopic surgical procedure, requiring extensive knowledge, skill, and specialized equipment. ESD starts with evaluation of the lesion, as accurate assessment of the depth and margin of the lesion is essential. The devices and strategies used in ESD vary, depending on the nature of the lesion. Prior to the procedure, the operator must be knowledgeable about the treatment strategy(ies), the device(s) to use, the electrocautery machine settings, the substances to inject, and other aspects. In addition, the operator must be able to manage complications, should they arise, including immediate recognition of the complication(s) and its treatment. Finally, in case the ESD treatment is not successful, the operator should be prepared to apply alternative treatments. Thus, adequate knowledge and training are essential to successfully perform ESD.

Abstract
BACKGROUND The technique of endoscopic submucosal dissection (ESD), which was developed for en bloc resection of large lesions in the stomach, has been widely accepted for the treatment of early gastric cancer. It is being used for muscularis propria tumors of the digestive tract and has produced positive therapeutic effects. OBJECTIVE To study the feasibility of ESD for the removal of esophageal muscularis propria tumors and to evaluate the efficacy and safety of ESD for this treatment. DESIGN Single-center, retrospective study. SETTING University hospital. PATIENTS Thirty esophageal muscularis propria tumors from 28 patients were treated with ESD between December 2008 and December 2010. We defined esophageal muscularis propria tumors as esophageal submucosal tumors originating from the muscularis propria layer. INTERVENTION ESD. MAIN OUTCOME MEASUREMENTS Tumor characteristics, complications, en bloc resection rate, and local recurrence rate were evaluated. RESULTS Among the 28 patients, 11 were women (39.3%). The median age was 49.32 years (range 22-62 years). Mean (± SD) tumor size was 1.25 ± 0.70 cm (range 0.5-3.0 cm). Except for 2 failed cases (one changed to surgery and the other changed to nylon ligation), 26 cases with 28 tumors (2 cases had 2 tumors) originating from the muscularis propria of the esophagus were successfully resected by ESD. The en bloc resection rate was 93.3% (28/30). The median ESD procedure time was 73.5 minutes (range 30-120 minutes). Perforation occurred in 2 cases during dissection of the lesion, which was closed with metal endoclips. Pneumothorax occurred after the treatment in both cases. Closed thoracic drainages were initiated, and the patients recovered quickly without surgery. Pathological examination confirmed 27 leiomyomas and 1 GI stromal tumor. The curative resection rate was 100% (28/28). There was no recurrence during a 3 to 27-month follow-up period. LIMITATIONS The limitation of the study was its retrospective design. CONCLUSION ESD offers the promise of localized treatment of esophageal muscularis propria tumors with relatively few complications and low mortality. It makes the resection of whole lesions possible and provides precise histologic information.

Abstract
The clinical outcomes of treatments for several medical conditions are better in teaching hospitals than in non-teaching hospitals. However, there is only limited information for comparisons of the clinical outcomes of bleeding peptic ulcers between teaching and non-teaching hospitals. A total of 4,863 patients treated by endoscopic hemostasis on admission for bleeding peptic ulcers were evaluated in 586 hospitals of the Diagnosis Procedure Combination (DPC) system. We collected their data from the database associated with the DPC system to compare the risk-adjusted length of stay (LOS) and in-hospital mortality within 30 days with respect to the hospital characteristics. The hospitals were categorized into two groups: teaching hospitals that were certified by the Japanese Society of Gastroenterology (3,332 patients in 360 hospitals) and non-teaching hospitals (1,531 patients in 226 hospitals). There was no significant difference with regard to the mean LOS and the crude in-hospital mortality within 30 days between groups (p = 0.181 and 0.174, respectively). Multiple linear regression analyses revealed that the hospital characteristics were not associated with the risk-adjusted LOS. The standardized coefficient for non-teaching hospitals was 0.019 (p = 0.172). Multiple logistic regression analyses further showed no significant difference in the in-hospital mortality within 30 days (non-teaching hospitals, odds ratio = 1.35, 95% confidence interval = 0.786 - 2.319, p = 0.277). In conclusion, both teaching and non-teaching hospitals have equivalent qualities in management of bleeding peptic ulcers. These findings suggest that the standardization of medical treatments for bleeding peptic ulcers has become disseminated in Japan.
