National survey questionnaire on the diagnosis and treatment status of Helicobacter pylori in peptic ulcer bleeding disease.

Background and objective: The Maastricht VI/Florence Consensus and Chinese National Consensus Report provide comprehensive guidelines for treating Helicobacter pylori infection. This study aimed to assess physicians' understanding of and adherence to this consensus in different hospitals. Methods: Chinese medical staff attending gastrointestinal conferences across various regions were selected for this study. The questionnaire included: 1. the number of patients with peptic ulcer bleeding in hospitals of different levels annually and the diagnostic methods used for H. pylori; 2. whether routine H. pylori examination was conducted and the specific methods employed; and 3. Treatment plans for H. pylori eradication; 4. The mean follow-up duration after treatment 5. Plans for re-eradication in cases of H. pylori treatment failure. Results: Across all levels of Chinese hospitals, the urea breath test was the most commonly used method for detecting H. pylori infection. Most primary (81.53%), secondary (89.49%), and tertiary (91.42%) centers opted for a 14-day quadruple regimen. The preferred antibiotic regimen at all hospital levels was amoxicillin+clarithromycin, with rates of 63.69, 58.08, and 59.27% in the primary, secondary, and tertiary hospitals, respectively. The rates of H. pylori re-examination were 68.15, 87.07, and 87.46% in the primary, secondary, and tertiary hospitals. If H. pylori eradication failed, hospitals at different levels choose to replace the initial plan. Conclusion: There is a need for an enhanced understanding of and adherence to guidelines for H. pylori among physicians in hospitals at all levels.

Endoscopic treatment options in peptic ulcer bleeding.

This review evaluates the evidence for the use of over-the-scope clips (OTSC), topical haemostatic agents (THA), and prophylactic embolisation (PE) in patients with peptic ulcer bleeding (PUB). The use of OTSC and THA may have the potential to increase the rate of endoscopic haemostasis in PUB not responding to conventional endoscopic treatment. In patients at high risk of recurrent bleeding, the performance of PE after achieving endoscopic haemostasis can reduce the risk of rebleeding and the need for surgery. Implementation of a local treatment protocol including these modalities may improve patient outcomes.

Impact of peptic ulcer bleeding on the in-hospital outcomes of cirrhotic patients with acute gastrointestinal bleeding: an international multicenter study.

OBJECTIVES: Peptic ulcer is the most common source of non-variceal bleeding. However, it remains controversial whether the outcomes of cirrhotic patients with peptic ulcer bleeding differ from those with variceal bleeding. METHODS: Cirrhotic patients with acute gastrointestinal bleeding (AGIB) who underwent endoscopy and had an identifiable source of bleeding were retrospectively screened from an international multicenter cohort. Logistic regression analyses were performed to explore the impact of peptic ulcer bleeding on in-hospital death and 5-day failure to control bleeding. Propensity score matching (PSM) analysis was performed by matching age, gender, Child-Pugh score, and model for end-stage liver disease score between the peptic ulcer bleeding and variceal bleeding groups. RESULTS: Overall, 1535 patients were included, of whom 73 (4.7%) had peptic ulcer bleeding. Multivariate logistic regression analyses showed that peptic ulcer bleeding was not independently associated with in-hospital death (OR = 2.169, p = 0.126) or 5-day failure to control bleeding (OR = 1.230, p = 0.680). PSM analyses demonstrated that both in-hospital mortality (9.7% vs. 6.3%, p = 0.376) and rate of 5-day failure to control bleeding (6.9% vs. 5.4%, p = 0.787) were not significantly different between the two groups. CONCLUSIONS: The impact of peptic ulcer bleeding on the in-hospital outcomes of cirrhotic patients is similar to that of variceal bleeding.

In this international multicenter study, we included 1535 patients with acute gastrointestinal bleeding (AGIB) and divided them into peptic ulcer bleeding and variceal bleeding groups. We found that only a minority of AGIB episodes in cirrhotic patients was attributed to peptic ulcer. Additionally, after adjusting for the severity of liver dysfunction, the in-hospital mortality and the rate of 5-day failure to control bleeding should be similar between cirrhotic patients with peptic ulcer bleeding and those with variceal bleeding.

Efficacy of routine second-look endoscopy after endoscopic hemostasis in patients with acute peptic ulcer bleeding: systematic review and meta-analysis.

OBJECTIVE: To evaluate the efficacy of scheduled second-look endoscopy in patients with acute peptic ulcer bleeding (PUB). MATERIALS AND METHODS: We systematically search in four databases for randomized controlled trials (RCTs) that evaluated the usefulness of scheduled second-look endoscopy vs. single endoscopy in patients with PUB. Our primary outcome was rebleeding. Secondary outcomes were surgery, mortality, and the number of units of blood transfused (NUBT). All meta-analyses were performed using a random-effects model. Pooled risk ratio (RR) and mean difference (MD), with their 95% confidence intervals (CIs) were calculated for categorical and continuous outcomes, respectively. The risk of bias was assessed using the Cochrane RoB 2.0 tool, and the quality of evidence (QoE) was rated with the GRADE approach. RESULTS: Eight full-text RCTs and two RCT abstracts were included (n=1513). We did not find differences in rebleeding (RR, 0.78; 95% CI, 0.53-1.14, moderate QoE), surgery (RR, 0.58; 95% CI, 0.29-1.15, moderate QoE), mortality (RR, 0.89; 95% CI, 0.46-1.71, moderate QoE) or NUBT (MD, -0.01 units; 95% CI, -0.3 to 0.28, low QoE) between second-look and single endoscopy. Sensitivity analyses had similar results to the main analyses. CONCLUSIONS: Routine second-look endoscopy was not more efficacious than single endoscopy in patients with PUB.

Ideal strategy for nonvariceal upper gastrointestinal bleeding.

PURPOSE OF REVIEW: Over 300 000 hospital admissions in the United States each year are due to patients with upper gastrointestinal (GI) bleeding (UGIB). Common etiologies of nonvariceal UGIB include peptic ulcers, mucosal erosions of the esophagus, stomach or duodenum, Mallory-Weiss tears, Dieulafoy lesions, upper GI tract malignancy, or other etiology. RECENT FINDINGS: Peptic ulcers classified as Forrest Ia, Ib, or IIa require endoscopic hemostasis, while IIb ulcers may be considered for endoscopic clot removal with endoscopic treatment of any underlying major stigmata. Endoscopic hemostasis for ulcers classified as Forrest IIc or III is not advised due to the low risk of recurrent bleeding. Endoscopic hemostasis in ulcer bleeding can be achieved using injection, thermal, and/or mechanical modalities. SUMMARY: This review focuses on the currently recommended endoscopic therapies of patients presenting with acute nonvariceal upper gastrointestinal hemorrhage.

Over-the-scope clip as first-line treatment of peptic ulcer bleeding: a multicenter randomized controlled trial (TOP Study).

BACKGROUND: First-line over-the-scope (OTS) clip treatment has shown higher efficacy than standard endoscopic therapy in acute nonvariceal upper gastrointestinal bleeding (NVUGIB) from different causes. We compared OTS clips with through-the-scope (TTS) clips as first-line mechanical treatment in the specific setting of peptic ulcer bleeding. METHODS: We conducted an international, multicenter randomized controlled trial on consecutive patients with suspected NVUGIB. Patients with Forrest Ia-IIb gastroduodenal peptic ulcer were randomized 1:1 to OTS clip or TTS clip treatment. The primary outcome was the rate of 30-day rebleeding after successful initial hemostasis. Secondary outcomes included the rates of successful initial hemostasis and overall clinical success, defined as the composite of successful initial hemostasis and no evidence of 30-day rebleeding. RESULTS: 251 patients were screened and 112 patients were randomized to OTS (n = 61) or TTS (n = 51) clip treatment. The 30-day rebleeding rates were 1.6% (1/61) and 3.9% (2/51) in patients treated with OTS clips and TTS clips, respectively (Kaplan-Meier log-rank, P = 0.46). Successful initial hemostasis rates were 98.4% (60/61) in the OTS clip group and 78.4% (40/51) in the TTS clip group (P = 0.001). Overall clinical success rates were 96.7% (59/61) with OTS clips and 74.5% (38/51) with TTS clips (P = 0.001). CONCLUSIONS: Low rates of 30-day rebleeding were observed after first-line endoscopic treatment of acute peptic ulcer bleeding with either OTS or TTS clips. However, OTS clips showed higher efficacy than TTS clips in achieving successful initial hemostasis and overall clinical success.

Comparison of Vonoprazan Versus Intravenous Proton Pump Inhibitor for Prevention of High-Risk Peptic Ulcers Rebleeding After Successful Endoscopic Hemostasis: A Multicenter Randomized Noninferiority Trial.

BACKGROUND & AIMS: High-dose proton pump inhibitor (PPI) therapy has been recommended to prevent rebleeding of high-risk peptic ulcer (PU) after hemostasis. Vonoprazan has been proven to be noninferior to PPIs in various acid-related diseases. This study aimed to compare the efficacy of vonoprazan vs PPI for preventing high-risk PU rebleeding after hemostasis. METHODS: A multicenter, randomized, noninferiority study was conducted in 6 centers. Pre-endoscopic and endoscopic therapy were performed according to standard protocol. After successful hemostasis, patients with high-risk PU bleeding (Forrest class Ia/Ib, IIa/IIb) were randomized into 1:1 to receive vonoprazan (20 mg twice a day for 3 days, then 20 mg once a day for 28 days) or high-dose PPI (pantoprazole intravenous infusion 8 mg/h for 3 days, then omeprazole 20 mg twice a day for 28 days). The primary outcome was a 30-day rebleeding rate. Secondary outcomes included 3- and 7-day rebleeding rate, all-cause and bleeding-related mortality, rate of rescue therapy, blood transfusion, length of hospital stay, and safety. RESULTS: Of 194 patients, baseline characteristics, severity of bleeding, and stage of ulcers were comparable between the 2 groups. The 30-day rebleeding rates in vonoprazan and PPI groups were 7.1% (7 of 98) and 10.4% (10 of 96), respectively; noninferiority (within 10% margin) of vonoprazan to PPI was confirmed (%risk difference, -3.3; 95% confidence interval, -11.2 to 4.7; P < .001). The 3-day and 7-day rebleeding rates in the vonoprazan group remained noninferior to PPI (P < .001 by Farrington and Manning test). All secondary outcomes were also comparable between the 2 groups. CONCLUSION: In patients with high-risk PU bleeding, the efficacy of vonoprazan in preventing 30-day rebleeding was noninferior to intravenous PPI. (ClinicalTrials.gov, Number: NCT05005910).

Ulcer Bleeding in the United States: Epidemiology, Treatment Success, and Resource Utilization.

BACKGROUND AND GOALS: Peptic ulcer disease is the most frequent cause of upper gastrointestinal bleeding. We sought to establish the epidemiology and hemostasis success rate of the different treatment modalities in this setting. METHODS: Retrospective cohort study using the National Inpatient Sample. Non-elective adult admissions with a principal diagnosis of ulcer bleeding were included. The primary outcome was endoscopic, radiologic and surgical hemostasis success rate. Secondary outcomes were patients' demographics, in-hospital mortality and resource utilization. On subgroup analysis, gastric and duodenal ulcers were studied separately. Confounders were adjusted for using multivariate regression analysis. RESULTS: A total of 136,425 admissions (55% gastric and 45% duodenal ulcers) were included. The mean patient age was 67 years. The majority of patients were males, Caucasians, of lower income and high comorbidity burden. The endoscopic, radiological and surgical therapy and hemostasis success rates were 33.6, 1.4, 0.1, and 95.1%, 89.1 and 66.7%, respectively. The in-hospital mortality rate was 1.9% overall, but 2.4% after successful and 11.1% after failed endoscopic hemostasis, respectively. Duodenal ulcers were associated with lower adjusted odds of successful endoscopic hemostasis, but higher odds of early and multiple endoscopies, endoscopic therapy, overall and successful radiological therapy, in-hospital mortality, longer length of stay and higher total hospitalization charges and costs. CONCLUSIONS: The ulcer bleeding endoscopic hemostasis success rate is 95.1%. Rescue therapy is associated with lower hemostasis success and more than a ten-fold increase in mortality rate. Duodenal ulcers are associated with worse treatment outcomes and higher resource utilization compared with gastric ulcers.

Risk factors for rebleeding and mortality following prophylactic transarterial embolization for patients with high-risk peptic ulcer bleeding: a single-center retrospective cohort study.

BACKGROUND: To investigate factors associated with risk for rebleeding and 30-day mortality following prophylactic transarterial embolization in patients with high-risk peptic ulcer bleeding. METHODS: We retrospectively reviewed medical records and included all patients who had undergone prophylactic embolization of the gastroduodenal artery at Rigshospitalet, Denmark, following an endoscopy-verified and treated peptic Sulcer bleeding, from 2016 to 2021. Data were collected from electronic health records and imaging from the embolization procedures. Primary outcomes were rebleeding and 30-day mortality. We performed logistical regression analyses for both outcomes with possible risk factors. Risk factors included: active bleeding; visible hemoclips; Rockall-score; anatomical variants; standardized embolization procedure; and number of endoscopies prior to embolization. RESULTS: We included 176 patients. Rebleeding occurred in 25% following embolization and 30-day mortality was 15%. Not undergoing a standardized embolization procedure increased the odds of both rebleeding (odds ratio 3.029, 95% confidence interval (CI) 1.395-6.579) and 30-day overall mortality by 3.262 (1.252-8.497). More than one endoscopy was associated with increased odds of rebleeding (odds ratio 2.369, 95% CI 1.088-5.158). High Rockall-score increased the odds of 30-day mortality (odds ratio 2.587, 95% CI 1.243-5.386). Active bleeding, visible hemoclips, and anatomical variants did not affect risk of rebleeding or 30-day mortality. Reasons for deviation from standard embolization procedure were anatomical variations, targeted treatment without embolizing the gastroduodenal artery, and technical failure. CONCLUSIONS: Deviation from the standard embolization procedure increased the risk of rebleeding and 30-day mortality, more than one endoscopy prior to embolization was associated with higher odds of rebleeding, and a high Rockall-score increased the risk of 30-day mortality. We suggest that patients with these risk factors are monitored closely following embolization. Early detection of rebleeding may allow for proper and early re-intervention.

Endoscopic Diagnosis, Grading, and Treatment of Bleeding Peptic Ulcer Disease.

Peptic ulcer bleeding is a major cause for hospital admissions and has a significant mortality. Endoscopic interventions reduce the risk of rebleeding in high-risk patients and several options are available including injection therapies, thermal therapies, mechanical clips, hemostatic sprays, and endoscopic suturing. Proton-pump inhibitors and Helicobacter pylori treatment are important adjuncts to endoscopic therapy. Endoscopic therapy is indicated in Forrest 1a, 1b, and 2a lesions. Patients with Forrest 2b lesions may do well with proton-pump inhibitor therapy alone but can also be managed by removal of the clot and targeting endoscopic therapy to the underlying lesion.

Factors influencing re-bleeding after trans-arterial embolization for endoscopically unmanageable peptic ulcer bleeding.

BACKGROUND/AIMS: Acute peptic ulcer bleeding is the most common cause of non-variceal upper gastrointestinal bleeding (NVUGIB). Endoscopic hemostasis is the standard treatment. However, various conditions complicate endoscopic hemostasis. Transarterial visceral embolization (TAE) may be helpful as a rescue therapy. This study aimed to investigate the factors associated with rebleeding after TAE. METHODS: We retrospectively investigated the records of 156 patients treated with TAE between January 2007 and December 2021. Rebleeding was defined as the presence of melena, hematemesis, or hematochezia, with a fall (>2.0 g/dl) in hemoglobin level or shock after TAE. The primary outcomes were rebleeding rate and 30-day mortality. RESULTS: Seventy patients with peptic ulcer bleeding were selected, and rebleeding within a month after TAE occurred in 15 patients (21.4%). Among the patients included in rebleeding group, significant increases were observed in the prevalence of thrombocytopenia (73.3% vs. 16.4%, p<.001) and ulcers >1 cm (93.3% vs 54.5%, p = .014). The mean AIMS65 (albumin, international normalized ratio, mental status, systolic blood pressure, age >65 years) score (2.3 vs 1.4, p = .009) was significantly higher in the rebleeding group. Multivariate logistic analysis revealed that thrombocytopenia (odds ratio 31.92, 95% confidence interval 6.24-270.6, p<.001) and larger ulcer size (odds ratio 27.19, 95% confidence interval 3.27-677.7, p=.010) significantly increased the risk of rebleeding after TAE. CONCLUSION: TAE was effective in the treatment of patients with high-risk peptic ulcer bleeding. AIMS65 score was a significant predictor of rebleeding after TAE, and thrombocytopenia and larger ulcer size increased the risk of rebleeding after TAE.

Risk factors for rebleeding in gastroduodenal ulcers.

BACKGROUND: Rebleeding after hemostasis of the gastroduodenal ulcer (GDU) is one of the indicators associated with death among GDU patients. However, there are few studies on risk score that contribute to rebleeding after endoscopic hemostasis of bleeding peptic ulcers. AIMS: The aim of this study was to identify factors associated with rebleeding, including patient factors, after endoscopic hemostasis of bleeding gastroduodenal ulcers and to stratify the risk of rebleeding. METHODS: We retrospectively enrolled 587 consecutive patients who were treated for Forrest Ia to IIa bleeding gastroduodenal ulcers with endoscopic hemostasis at three institutions. Risk factors associated with rebleeding were assessed using univariate and multivariate logistic regression analyses. The Rebleeding Nagoya University (Rebleeding-N) scoring system was developed based on the extracted factors. The Rebleeding-N score was internally validated using bootstrap resampling methods. RESULTS: Sixty-four patients (11%) had rebleeding after hemostasis of gastroduodenal ulcers. Multivariate logistic regression analysis revealed four independent rebleeding risk factors: blood transfusion, albumin <2.5, duodenal ulcer, and diameter of the exposed vessel ≧2 mm. Patients with 4 risk factors in the Rebleeding-N score had a 54% rebleeding rate, and patients with 3 risk factors had 44% and 25% rebleeding rates. In the internal validation, the mean area under the curve of the Rebleeding-N score was 0.830 (95% CI = 0.786-0.870). CONCLUSIONS: Rebleeding after clip hemostasis of bleeding gastroduodenal ulcers was associated with blood transfusion, albumin <2.5, diameter of the exposed vessel ≧2 mm, and duodenal ulcer. The Rebleeding-N score was able to stratify the risk of rebleeding.

Duodenal ulcer bleeding from a branch of the middle colic artery: A case report.

RATIONALE: Duodenal ulcer bleeding is a potentially life-threatening condition commonly caused by the erosion of the duodenal arteries. PATIENT CONCERNS: A 55-year-old male was referred to our hospital with abdominal pain for the past 3 days. Contrast-enhanced computed tomography of the abdomen revealed wall thickening in the descending part of the duodenum and a cystic lesion (27 × 19 mm) contiguous with the duodenum, with an accumulation of fluid. An esophagogastroduodenoscopy showed the significantly stenotic duodenum, which prevented passage of the endoscope and evaluation of the main lesion. Based on these findings, duodenal ulcer perforation and concomitant abscess formation were suspected. Two days after admission, he had massive hematochezia with bloody drainage from the nasogastric tube. DIAGNOSES: Emergency angiography revealed duodenal ulcer bleeding from the gastroduodenal artery and the branch artery of the inferior pancreaticoduodenal artery and middle colic artery (MCA). INTERVENTIONS: The patient was treated with transcatheter arterial embolization (TAE) of the gastroduodenal artery, the branch vessel of the inferior pancreaticoduodenal artery, and the main trunk of the MCA. OUTCOMES: Hemostasis was achieved with TAE. The patient recovered uneventfully and undergone a gastro-jejunal bypass surgery for the duodenal stenosis 2 weeks after TAE. He was discharged without any abnormal complaints on postoperative day 12. LESSONS: We have experienced a rare case of duodenal ulcer bleeding from a branch of the MCA. In patients with refractory upper gastrointestinal bleeding, careful evaluation of bleeding sites is recommended considering unexpected culprit vessels.

Comparison and validation of the Japanese score and other scoring systems in patients with peptic ulcer bleeding: A retrospective study.

Acute upper gastrointestinal bleeding (UGIB) is one of the most urgent medical conditions, with peptic ulcer bleeding (PUB) accounting for most gastrointestinal bleeding cases. The Japanese scoring system was developed to predict the probability of intervention in patients with UGIB, and it is more effective than other scoring systems, according to several studies. This study aimed to verify whether the Japanese scoring system is better than other scoring systems in predicting the probability of intervention when limited to PUB in patients with UGIB. We enrolled patients who presented with symptoms of UGIB and were diagnosed with peptic ulcers using endoscopy. The performances of the scoring systems in predicting patient outcomes were validated and compared using the receiver-operating characteristic curve analysis. Additionally, we used the chi-square test, Fisher exact test, and the t test to analyze the association between the patients characteristics and clinical outcomes. Of the 1228 patients diagnosed with peptic ulcers, 90.6% underwent endoscopy. rebleeding occurred in 12.5% of the patients, and 2.5% of the patients died within 30 days. The Japanese score was the most effective in predicting the need for endoscopic intervention for PUB. Sex, systolic blood pressure, hematemesis, syncope, blood urea nitrogen level, and the American Society of Anesthesiologists score were predictive factors for the probability of endoscopic intervention in patients with PUB. The Japanese score is an effective predictor of the probability of endoscopic intervention in patients with PUB.
