Upper gastrointestinal bleeding due to Dieulafoy's lesion of the stomach: a rare case report

Dieulafoy's lesion is a life-threatening and rare vascular malformation of the submucosal vessel that protrudes to the mucosa of the gastrointestinal tract. The vessel is abnormally dilated, and if it ruptures, it can cause severe acute gastrointestinal bleeding. We report an upper GI bleeding case due to Dieulafoy's lesion in the gastric fundus of the stomach in a 76-year-old female. The patient presented with hematemesis and melena associated with anemia. An esophagogastroduodenoscopy (OGD) was performed which showed profuse pulsatile bleeding at the gastric fundus. Following that, gastrotomy confirmed the diagnosis of Dieulafoy's lesion. Endoscopy is the main diagnostic and therapeutic tool for Dieulafoy's lesion. Endoscopic treatment includes injective, ablative and mechanical therapies. The majority of cases are treated endoscopically, while in some cases, surgical intervention is deemed to be necessary as it is currently the only definitive treatment of Dieulafoy's lesion.

Pre-Endoscopic Scores Predicting Low-Risk Patients with Upper Gastrointestinal Bleeding: A Systematic Review and Meta-Analysis

BACKGROUND

Several risk scores have attempted to risk stratify patients with acute upper gastrointestinal bleeding (UGIB) who are at a lower risk of requiring hospital-based interventions or negative outcomes including death. This systematic review and meta-analysis aimed to compare predictive abilities of pre-endoscopic scores in prognosticating the absence of adverse events in patients with UGIB.

METHODS

We searched MEDLINE, EMBASE, Central, and ISI Web of knowledge from inception to February 2023. All fully published studies assessing a pre-endoscopic score in patients with UGIB were included. The primary outcome was a composite score for the need of a hospital-based intervention (endoscopic therapy, surgery, angiography, or blood transfusion). Secondary outcomes included: mortality, rebleeding, or the individual endpoints of the composite outcome. Both proportional and comparative analyses were performed.

RESULTS

Thirty-eight studies were included from 2153 citations, (n = 36,215 patients). Few patients with a low Glasgow-Blatchford score (GBS) cutoff (0, ≤1 and ≤2) required hospital-based interventions (0.02 (0.01, 0.05), 0.04 (0.02, 0.09) and 0.03 (0.02, 0.07), respectively). The proportions of patients with clinical Rockall (CRS = 0) and ABC (≤3) scores requiring hospital-based intervention were 0.19 (0.15, 0.24) and 0.69 (0.62, 0.75), respectively. GBS (cutoffs 0, ≤1 and ≤2), CRS (cutoffs 0, ≤1 and ≤2), AIMS65 (cutoffs 0 and ≤1) and ABC (cutoffs ≤1 and ≤3) scores all were associated with few patients (0.01-0.04) dying. The proportion of patients suffering other secondary outcomes varied between scoring systems but, in general, was lowest for the GBS. GBS (using cutoffs 0, ≤1 and ≤2) showed excellent discriminative ability in predicting the need for hospital-based interventions (OR 0.02, (0.00, 0.16), 0.00 (0.00, 0.02) and 0.01 (0.00, 0.01), respectively). A CRS cutoff of 0 was less discriminative. For the other secondary outcomes, discriminative abilities varied between scores but, in general, the GBS (using cutoffs up to 2) was clinically useful for most outcomes.

CONCLUSIONS

A GBS cut-off of one or less prognosticated low-risk patients the best. Expanding the GBS cut-off to 2 maintains prognostic accuracy while allowing more patients to be managed safely as outpatients. The evidence is limited by the number, homogeneity, quality, and generalizability of available data and subjectivity of deciding on clinical impact. Additional, comparative and, ideally, interventional studies are needed.

Giant Hyperplastic Polyp at the Gastroesophageal Junction: A Rare Provocateur of Upper Gastrointestinal Bleeding

Esophageal hyperplastic polyps (HPs) are a rare benign polypoidal growth most commonly resulting from gastroesophageal reflux disease (GERD). The lesion is asymptomatic in most patients unless large enough to cause luminal obstruction or gastrointestinal bleeding. The treatment of choice is endoscopic resection if it becomes symptomatic. Here, we report a case of a 51-year-old woman presenting with dyspeptic symptoms and upper gastrointestinal bleeding. An upper gastrointestinal endoscopy showed a large polyp with active oozing of blood at the gastroesophageal junction (GEJ), which was removed endoscopically after injecting adrenaline at its base. Histopathological analysis was suggestive of HPs.

Testicular Mixed Germ Cell Tumor Presenting with Upper Gastrointestinal Bleeding: A Case Report

Testicular mixed germ cell tumors (TMGCTs) are aggressive neoplasms that often have metastases at the time of diagnosis, primarily in the lungs, bones, and brain. Gastrointestinal metastases are rare, occurring in less than 5% of cases, while duodenal involvement is extremely rare, with only few reported cases. Furthermore, gastrointestinal bleeding is an atypical initial presentation of metastatic TMGCTs. Herein, we present a very rare case of upper gastrointestinal bleeding caused by a duodenal metastasis of a TMGCT in a 24-year-old man. The patient was admitted to our hospital due to abdominal pain and melena with a hemoglobin level of 52 g/L. He had no history of testicular swelling, or any other symptoms or signs of a testicular tumor. Upper gastrointestinal endoscopy revealed a duodenal tumor mass with irregular bleeding, and abdominal ultrasound and computed tomography showed a duodenal mass that infiltrate retroperitoneum. Emergency surgery was performed, and the histopathological findings of the resected specimen were consistent with TMGCT metastasis. Subsequently, a testicular tumor was confirmed and surgically removed; however, multiple metastatic deposits were observed in the lungs. Due to the patient's poor general condition, chemotherapy was not performed. The patient died 3 months after the initial diagnosis. This case suggests that, although duodenal metastatic TMGCTs are rare, they should be considered in the differential diagnosis of gastrointestinal bleeding in young male patients.

Efficacy of endoscopic therapy and long-term outcomes of upper gastrointestinal tumor bleeding in patients with esophageal cancer

BACKGROUND

Upper gastrointestinal bleeding (UGIB) from malignancies is associated with a poor outcome. Only a small number of studies on gastrointestinal tumor bleeding have been published so far, focusing mainly on bleeding from gastric cancer. Since the information on patients with UGIB from esophageal cancer appears insufficient, this study aimed to present clinical and endoscopic findings, treatment options as well as clinical outcomes such as rebleeding and survival of those patients.

METHODS

This retrospective analysis included all patients admitted with UGIB from esophageal cancer at our university hospital during a 10-year period.

RESULTS

45 patients were analyzed of whom 26 (57.8%) already had cancer stage IV at index bleeding. 22 (48.9%) patients presented with hemodynamic instability and 30 (66.7%) patients received blood transfusions. Active bleeding was present in 24 (53.3%) patients, of whom 20 (83.3%) received endoscopic therapy. Successful hemostasis was achieved in 18 (90%) of 20 patients with Argon plasma coagulation used most frequently (52.4%). Early and delayed rebleeding occurred in 5 (12.5%) and 11 (27.5%) of all inoperable patients, respectively. Intake of anticoagulation or anti-platelet drugs were risk factors for delayed rebleeding and the median overall survival after index bleeding was 1.2 months.

CONCLUSION

UGIB from esophageal cancer occurred most frequently in advanced tumor stages and was associated with significant blood loss. Even though initial endoscopic therapy was effective, rebleeding occurred in a significant number of patients. Those taking anticoagulants or anti-platelet drugs should be closely monitored for rebleeding. The overall survival after index bleeding was poor.

Adherence to guidelines in patients with non-variceal upper gastrointestinal bleeding (UGIB) - results from a retrospective single tertiary center registry

BACKGROUND

Guidelines for the management of upper gastrointestinal bleeding (UGIB) are regularly published, yet little is known concerning adherence to recommendations in practice.

OBJECTIVES

We aimed to assess adherence to European Society of Gastrointestinal Endoscopy (ESGE) recommendations in patients with non-variceal UGIB.

MATERIALS AND METHODS

All hospitalized patients with an esophagogastroduodenoscopy (EGD) performed due to suspected non-variceal UGIB at our department were included in a prospective registry. Data between 2018-2020 from this registry were retrospectively analyzed. Adherence to the 2015 ESGE bleeding and propofol sedation guidelines was assessed. Adherence to recommendations concerning preendoscopic (risk) evaluation, preendoscopic PPI, transfusion management, and endoscopic management of peptic ulcers was analyzed.

RESULTS

Among 1005 patients (mean age 70.4 years, 42.1% women) the most common bleeding etiologies were gastric or duodenal ulcers (16.8%), esophagitis/GERD (11.1%), and angiodysplasia (9.9%); mortality was 7.6%. Adherence to preendosopic risk evaluation was low, in 0% a Mallampati classification and in 37.5% an ASA scoring was documented. Preendoscopic PPI was started at 58.6%, and adherence to recommended transfusion management was >98%. Peptic ulcers were Forrest-graded in 72.8%. High-risk ulcers were treated appropriately in 77.9% and low-risk ulcers were not treated in 73.6%. Especially Forrest Ib ulcers were undertreated, with an adherence of 59.6%. Only 22/179 (12.3%) patients with peptic ulcers and early endoscopy were consistently managed according to ESGE recommendations.

CONCLUSIONS

Adherence to ESGE guidelines in patients with non-variceal UGIB is moderate to low, even at a tertiary university hospital. Strategies must be devised for guidelines to reach patients in everyday practice.

The COVID-19 Infection Resulted Delayed Esophagogastroduodenoscopy in Patients Admitted with Variceal Bleeding: Hospital-Based Outcomes of a National Database

During the COVID-19 pandemic in 2020, most healthcare services, including inpatient and outpatient procedures, got delayed. We reviewed the effect of COVID-19 infection on the timing of esophagogastroduodenoscopy (EGD) in variceal bleeding patients and analyzed the complications of delayed EGD. Using the National Inpatient Sample (NIS) 2020, we identified patients admitted for variceal bleeding with COVID-19 infection. We performed a multivariable regression analysis and adjusted it for patient and hospital-related variables. The International Classification of Disease Tenth Revision (ICD-10) codes were used for patient selection. We measured the effect of COVID-19 on the timing of EGD and further analyzed the effect of delayed EGD on hospital-based outcomes. A total of 49,675 patients diagnosed with variceal upper gastrointestinal bleeding were analyzed, out of which 915 (1.84%) were COVID-19 positive. Variceal bleeding patients who were COVID-positive had a significantly lower rate of EGD performed within the first 24 h of admission (36.1% vs. 60.6% p = 0.001) compared to the patients who tested negative for COVID-19. The performance of EGD within 24 h of admission resulted in a decrease in all-cause mortality by 70% (adjusted odds ratio (AOR) 0.30, 95% CI 0.12-0.76, p = 0.01) compared to EGD after 24 h. A significant decrease was noted in the odds of ICU admission rate (AOR 0.37, 95% CI 0.14-0.97, p = 0.04) in patients who got EGD within the first 24 h of admission. No difference in odds of sepsis (AOR 0.44, 95% CI 0.15-1.30, p = 0.14) and vasopressor use (AOR 0.34, 95% CI 0.04-2.87, p = 0.32) was seen in COVID positive vs. COVID negative group. The hospital mean length of stay (2.14 days, 95% CI 4.35-0.06, p = 0.06), mean total charges ($51,936, 95% CI $106,688-$2816, p = 0.06), and total cost (11,489$, 95% CI 30,380$-7402$, p = 0.23) was similar in both COVID-positive and -negative groups. In our study, we found that the presence of COVID-19 infection in variceal bleeding patients resulted in a significant delay in EGD compared to COVID-negative patients. This delay in EGD resulted in increased all-cause mortality and intensive care unit admissions.

Alcohol-related liver disease phenotype impacts survival after an acute variceal bleeding episode

BACKGROUND & AIMS

Alcohol-related hepatitis (AH) encompasses a high mortality. AH might be a concomitant event in patients with acute variceal bleeding (AVB). The current study aimed to assess the prevalence of AH in patients with AVB and to compare the clinical outcomes of AH patients to other alcohol-related liver disease (ALD) phenotypes and viral cirrhosis.

METHODS

Multicentre, observational study including 916 patients with AVB falling under the next categories: AH (n = 99), ALD cirrhosis actively drinking (d-ALD) (n = 285), ALD cirrhosis abstinent from alcohol (a-ALD) (n = 227) and viral cirrhosis (n = 305). We used a Cox proportional hazards model to calculate adjusted hazard ratio (HR) of death adjusted by MELD.

RESULTS

The prevalence of AH was 16% considering only ALD patients. AH patients exhibited more complications. Forty-two days transplant-free survival was worse among AH, but statistical differences were only observed between AH and d-ALD groups (84 vs. 93%; p = 0.005), when adjusted by MELD no differences were observed between AH and the other groups. At one-year, survival of AH patients (72.7%) was similar to the other groups; when adjusted by MELD mortality HR was better in AH compared to a-ALD (0.48; 0.29-0.8, p = 0.004). Finally, active drinkers who remained abstinent presented better survival, independently of having AH.

CONCLUSIONS

Contrary to expected, AH patients with AVB present no worse one-year survival than other patients with different alcohol-related phenotypes or viral cirrhosis. Abstinence influences long-term survival and could explain these counterintuitive results.

Unwitnessed Foreign Body Ingestion Causing Significant Morbidity in a Pediatric Patient Who Died During Resuscitation Secondary to Acute Upper Gastrointestinal Bleeding

Foreign body (FB) ingestion is a common presenting complaint to the emergency department in the pediatric age group; however, management and intervention vary based on the object ingested, location, time since ingestion, and clinical presentation. One of the rare presentations of foreign body ingestion is extreme complications such as upper gastrointestinal (GI) bleeding that requires urgent resuscitation and might need surgical intervention. We urge critical healthcare providers to consider foreign body ingestion in the differential diagnosis of acute unexplained upper gastrointestinal bleeding and maintain a high index of suspicion, and they must endeavor to obtain a complete history.

Practical Aspects of Upper Gastrointestinal Bleeding in Children

Upper gastrointestinal bleeding (UGB) in children is a potentially life-threatening condition that represents a challenge for pediatricians and pediatric surgeons. It is defined as bleeding from any location within the upper esophagus to the ligament of Treitz. UGB can have many causes that vary with age. The impact on the child is often proportional to the amount of blood lost. This can range from mild bleeding that is unlikely to cause hemodynamic instability, to massive bleeding that requires admission to the intensive care unit. Proper and prompt management are very important factors in reducing morbidity and mortality. This article aims to summarize current research regarding the diagnosis and treatment of UGB. Most of the data used in the literature published on this subject is extrapolated from adulthood.

Pulmonary biological glue embolism after endoscopic repair of gastric varices - A case report

Cyanoacrylate injection is widely used to treat hemorrhagic gastric varices. A pulmonary glue embolism is an unusual but potentially fatal complication. We present a case of a 51-year-old man with a history of alcoholic hepatic cirrhosis Child-Pugh B, who had an acute pulmonary embolism with sudden cardiorespiratory collapse due to biological glue injection used for the emergent repair of bleeding gastric varices. After the restoration of respiratory and hemodynamic parameters, he was admitted to the intensive care unit and the pulmonary biological glue emboli were documented with computed tomography scan. A high index of suspicion for this entity is essential in patients submitted to endoscopic sclerotherapy. Some might be asymptomatic or mildly symptomatic, while others might present with cardiorespiratory collapse.

Analysis of upper gastrointestinal bleeding complicated with deep vein thrombosis in elderly gastric cancer patients by gastric cancer imaging

Tumor imaging represents an ideal environment for collecting novel biomarkers from different technologies, as patients with tumors often undergo multiple imaging studies.With the aging of the Chinese population, the number of elderly patients with gastric cancer is also increasing. In the past, patients with gastric cancer in the elderly have been conservative in whether surgical treatment can be performed, and advanced age is regarded as a relative contraindication to the effect of surgical treatment on gastric cancer patients. To investigate the clinical characteristics of patients with upper gastrointestinal hemorrhage complicated by deep vein thrombosis in elderly patients with gastric cancer. One patient with upper gastrointestinal hemorrhage complicated by deep venous thrombosis, and elderly gastric cancer patients admitted to our hospital on 11 October 2020, were selected. After anti-shock symptomatic support, filter placement, prevention and treatment of thrombosis, gastric cancer eradication, anticoagulation, immune regulation, etc. Treatment and long-term follow-up observation. Long-term follow-up showed that the patient's condition was stable, there was no sign of metastasis or recurrence after radical gastrectomy for gastric cancer, and there were no serious pre- and post-operative complications such as upper gastrointestinal bleeding and deep vein thrombosis, and the prognosis was satisfactory. How to choose the appropriate operation timing and method for elderly gastric cancer patients with upper gastrointestinal bleeding and deep vein thrombosis at the same time to maximize benefits, clinical experience in this area is particularly valuable.

The Accuracy of Pre-Endoscopic Scores for Mortality Prediction in Patients with Upper GI Bleeding and No Endoscopy Performed

(1) Background: The assessment of mortality and rebleeding rate in upper gastrointestinal bleeding (UGIB) is essential, and several prognostic scores have been proposed. Some patients with UGIB did not undergo endoscopy, either because they refused the procedure, suffered from alcohol withdrawal symptoms or altered general status, or because the bleeding was severe enough to cause death before the endoscopy. The mortality risk in the subgroup of patients without endoscopy is poorly evaluated in the literature. (2) Methods: The purpose of the study was to identify the most useful scores for the assessment of in-hospital mortality in patients with UGIB with no endoscopy performed and no known etiology. A total of 198 patients with UGIB and no endoscopy performed were admitted between January 2017 and December 2021 and the accuracy of 12 prognostic scores and the Charlson comorbidity index for in-hospital mortality prediction were analyzed, as well as Child-Pugh Turcotte (CPT) and Meld scores in patients with cirrhosis. (3) Results: The mortality rate was 37.9%, higher than in variceal (21.9%, p < 0.0001) and non-variceal bleeding (7.4%, p < 0.0001). The most accurate scores by AUC were the International Bleeding score (INBS, 0.844), Glasgow Blatchford (0.783), MAP score (0.78), Iino (0.766), AIM65 and modified N-score (0.745 each), modified Glasgow-Blatchford (0.73), H3B2 and N-score (0.701); Rockall, Baylor, and T-score had an AUC below 0.7. MELD score was superior to CPT in patients with cirrhosis (AUC 0.811 versus 0.670). (4) Conclusions: The mortality rate in UGIB with no endoscopy was higher than in both variceal and non-variceal bleeding and was higher in the pandemic period but with no statistical significance (45.3% versus 32.14%, p = 0.0586), mainly because of positive cases. Only one case of rebleeding was noted; the hospitalization period was significantly shorter. The most accurate score was International Bleeding Score; the MELD score had a higher but moderate accuracy compared with CPT in patients with cirrhosis.

Clinical outcomes of Dieulafoy's lesion compared with peptic ulcer in upper gastrointestinal bleeding

BACKGROUND AND AIM

Although Dieulafoy's lesion (DL) is an important cause of nonvariceal upper gastrointestinal (GI) bleeding, few studies have investigated the clinico-epidemiological outcomes due to its rarity. Here, we investigated clinical features of upper GI bleeding caused by peptic ulcer (PU) or DL and compared endoscopic treatment outcomes.

METHODS

Patients with upper GI bleeding resulting from PU or DL who visited emergency room between January 2013 and December 2017 were eligible. Clinical features and treatment outcomes were retrospectively investigated.

RESULTS

Overall, 728 patients with upper GI bleeding due to PU (n = 669) and DL (n = 59) were enrolled. The median age was 64 years (interquartile range [IQR], 56-75 years), and 74.3% were male. Endoscopic intervention was performed in 53.7% (n = 359) and 98.3% (n = 58) of the PU and DL groups, respectively (P < 0.0001). Patients were matched by sex, age, body mass index, comorbidity, and past medical history, and 190 PU and 52 DL were finally selected. The rebleeding rates within 7 (7.37% vs 17.31%, P = 0.037) and 30 (7.37% vs 26.92%, P < 0.001) days after initial endoscopy were significantly lower in the PU than in the DL group after propensity score matching. During the median follow-up period of 52 months (IQR, 34-70 months), there was no difference in overall survival rate (67.9% vs 82.7%, P = 0.518).

CONCLUSIONS

Although DL is a rare cause of upper GI bleeding, it requires endoscopic hemostasis more frequently and has a higher rate of rebleeding than PU even after therapeutic endoscopy. Endoscopists should pay attention and perform active endoscopic hemostasis for DL bleeding.

Uncommon, overlooked and underreported causes of upper gastrointestinal bleeding

Upper gastrointestinal bleeding (UGB) is a potentially fatal consequence of digestive disorders. There is a wide range of rare causes for UGB that can lead to misdiagnosis and occasionally catastrophic outcomes. The lifestyles of those who are afflicted are mostly responsible for the underlying conditions that result in the hemorrhagic cases. The development of a novel approach targeted at raising public awareness of the issue and educating the public about it could significantly contribute to the elimination of gastrointestinal bleeding with no associated risks and to a nearly zero mortality rate. There are reports of UGB related to Sarcina ventriculi, gastric amyloidosis, jejunal lipoma, gastric schwannoma, hemobilia, esophageal varices, esophageal necrosis, aortoenteric fistula, homosuccus pancreaticus, and gastric trichbezoar in the literature. The common feature of these rare causes of UGB is that the diagnosis is difficult to establish before surgery. Fortunately, UGB with a clear lesion in the stomach itself is a clear sign for surgical intervention, and the diagnosis can only be verified by pathological examination with the help of immunohistochemical detection of a particular antigen for a specific condition. The clinical traits, diagnostic techniques, and the therapeutic, or surgical options of unusual causes of UGB reported in the literature are compiled in this review.

Prevalence and prognostic significance of vitamin C deficiency in patients with acute upper gastrointestinal bleeding: a prospective cohort study

BACKGROUND

Vitamin C is an essential dietary nutrient important for collagen synthesis, including within the gastrointestinal tract.

AIM

We aimed to document the prevalence of Vitamin C deficiency (VCD) in patients who present with upper gastrointestinal bleeding (UGIB) and its association with clinical outcomes.

METHODS

We conducted a prospective cohort study of patients presenting with UGIB. Fasting Vitamin C levels were collected at admission. Primary outcomes were the prevalence of VCD (Vitamin C level <23 μmol/L, severe VCD < 12 μmol/L) and a composite outcome of adverse events, stratified by VCD status. Secondary outcomes were prolonged hospitalisation and the need for ICU admission.

RESULTS

A total of 227 patients were included (mean age 64.5 years, males 63.9%). VCD was identified in 74 (32.6%) and severe deficiency in 32 (14.1%) patients. VCD was associated with a higher composite endpoint of AE (45.9% vs 24.8%, p < 0.01), higher in-hospital mortality (9.5% vs 1.3%, p < 0.01), increased prolonged admissions (62.2% versus 47.1%, p = 0.03) and increased rebleeding (17.6% vs 7.8%, p = 0.03), compared with patients with normal Vitamin C levels. Multivariate logistic regression models showed that VCD was independently associated with the composite endpoint of AE.

CONCLUSION

VCD is highly prevalent in patients with UGIB and associated with poorer outcomes, including higher mortality, rebleeding and length of stay. Interventional studies are required to determine the impact of early Vitamin C supplementation on clinical outcomes.

External validation and comparison of the Glasgow-Blatchford score, modified Glasgow-Blatchford score, Rockall score and AIMS65 score in patients with upper gastrointestinal bleeding: a cross-sectional observational study in Western Switzerland

Upper gastrointestinal bleeding (UGIB) presents a high incidence in an emergency department (ED) and requires careful evaluation of the patient's risk level to ensure optimal management. The primary aim of this study was to externally validate and compare the performance of the Rockall score, Glasgow-Blatchford score (GBS), modified GBS and AIMS65 score to predict death and the need for an intervention among patients with UGIB. This was a cross-sectional observational study of patients consulting the ED of a Swiss tertiary care hospital with UGIB. Primary outcomes were the inhospital need for an intervention, including transfusion, or an endoscopic procedure or surgery or inhospital death. The secondary outcome was inhospital death. We included 1521 patients with UGIB, median age, 68 (52-81) years; 940 (62%) were men. Melena or hematemesis were the most common complaints in 1020 (73%) patients. Among 422 (28%) patients who needed an intervention or died, 76 (5%) died in the hospital. Accuracy of the scoring systems assessed by receiver operating characteristic curves showed that the Glasgow-Blatchford bleeding and modified GBSs had the highest discriminatory capacity to determine inhospital death or the need of an intervention [AUC, 0.77 (95% CI, 0.75-0.80) and 0.78 (95% CI, 0.76-0.81), respectively]. AIMS65 and the pre-endoscopic Rockall score showed a lower discrimination [AUC, 0.68 (95% CI, 0.66-0.71) and 0.65 (95% CI, 0.62-0.68), respectively]. For a GBS of 0, only one patient (0.8%) needed an endoscopic intervention. The modified Glasgow-Blatchford and Glasgow-Blatchford bleeding scores appear to be the most accurate scores to predict the need for intervention or inhospital death.

Application of endoscopic purse-string sutures in high-risk peptic ulcer hemorrhage: preliminary experience of 38 cases

OBJECTIVE

This study is a prospective study to explore the therapeutic effect of endoscopic purse-string sutures in high-risk peptic ulcer hemorrhage.

PATIENTS AND METHODS

We prospectively collected and analyzed data from July 2018 to December 2020 from patients in Jinshan hospital, Fudan University, who underwent emergency endoscopy for acute severe high-risk non-variceal upper gastrointestinal hemorrhage (NVUGIB) and were treated with endoscopic purse-string sutures.

RESULTS

We included 38 patients whose median age was 64 years (interquartile range: 57.2 - 71.2 years). All patients were high risk gastric ulcer larger than 1 cm, including Forrest Ia (n = 4, 10.5%), Forrest Ib (n = 13, 34.2%) and Forrest IIa (n = 21, 55.3%). All patients were treated with endoscopic purse-string sutures. The clinical success rate reached 89.5%. Three patients suffered from rebleeding within seven days, and were treated with surgery or arterial embolization, respectively, all of which successfully stopped bleeding. One patient died of myocardial infarction. All other patients were followed up for 30 days without bleeding.

CONCLUSIONS

We conclude that endoscopic purse-string sutures seem to be safe and effective in the treatment of patients at high risk of ulcer bleeding.

Performance of the New ABC and MAP(ASH) Scores in the Prediction of Relevant Outcomes in Upper Gastrointestinal Bleeding

Background & Aims: Several risk scores have been proposed for risk-stratification of patients with upper gastrointestinal bleeding. ABC score was found more accurate predicting mortality than AIMS65. MAP(ASH) is a simple, pre-endoscopy score with a great ability to predict intervention and mortality. The aim of this study was to compare ABC and MAP(ASH) discriminative ability for the prediction of mortality and intervention in UGIB. As a secondary aim we compared both scores with Glasgow-Blatchford score and AIMS65. Methods: Our study included patients admitted to the emergency room of Virgen de las Nieves University Hospital with UGIB (2017-2020). Information regarding clinical, biochemical tests and procedures was collected. Main outcomes were in-hospital mortality and a composite endpoint for intervention. Results: MAP(ASH) and ABC had similar AUROCs for mortality (0.79 vs. 0.80). For intervention, MAP(ASH) (AUROC = 0.75) and ABC (AUROC = 0.72) were also similar. Regarding rebleeding, AUROCs of MAP(ASH) and ABC were 0.67 and 0.61 respectively. No statistically differences were found in these outcomes. With a low threshold for MAP(ASH) ≤ 2, ABC and MAP(ASH) classified a similar proportion of patients as being at low risk of death (42% vs. 45.2%), with virtually no mortality under these thresholds. Conclusions: MAP(ASH) and ABC were similar for the prediction of relevant outcomes for UGIB, such as intervention, rebleeding and in-hospital mortality, with an accurate selection of low-risk patients. MAP(ASH) has the advantage of being easier to calculate even without the aid of electronic tools.

Undifferentiated Carcinoma With Osteoclast-Like Giant Cells: A Rare Cause of Upper Gastrointestinal Bleeding

Undifferentiated osteoclast-like giant cell carcinomas (UOLGCCs) of the digestive tract are very rare, with only a few cases reported in the literature. An 82-year-old man was referred to the emergency department for melena. Endoscopic examination revealed a hemicircumferential ulcerovegetative lesion, involving the bulbar apex and extending to the second portion of the duodenum; biopsies revealed an UOLGCC. The patient underwent transfusion support therapy, and he was proposed for best supportive care. Duodenal UOLGCC is an extremely rare cause of upper gastrointestinal bleeding. Clinical findings and therapeutic approach represent a challenge in this pathology.

Hemostatic Powders in Non-Variceal Upper Gastrointestinal Bleeding: The Open Questions

Hemostatic powder (HP) is a relatively recent addition to the arsenal of hemostatic endoscopic procedures (HEPs) for gastrointestinal bleeding (GIB) due to benign and malignant lesions. Five types of HP are currently available: TC-325 (Hemospray™), EndoClot™, Ankaferd Blood Stopper^®, and, more recently, UI-EWD (Nexpowder^TM) and CEGP-003 (CGBio™). HP acts as a mechanical barrier and/or promotes platelet activation and coagulation cascade. HP may be used in combination with or as rescue therapy in case of failure of conventional HEPs (CHEPs) and also as monotherapy in large, poorly accessible lesions with multiple bleeding sources. Although the literature on HP is abundant, randomized controlled trials are scant, and some questions remain open. While HP is highly effective in inducing immediate hemostasis in GIB, the rates of rebleeding reported in different studies are very variable, and conditions affecting the stability of hemostasis have not yet been fully elucidated. It is not established whether HP as monotherapy is appropriate in severe GIB, such as spurting peptic ulcers, or should be used only as rescue or adjunctive therapy. Finally, as it can be sprayed on large areas, HP could become the gold standard in malignancy-related GIB, which is often nonresponsive or not amenable to treatment with CHEPs as a result of multiple bleeding points and friable surfaces. This is a narrative review that provides an overview of currently available data and the open questions regarding the use of HP in the management of non-variceal upper GIB due to benign and malignant diseases.

Case report: Recurrent hemobilia due to hepatic artery pseudoaneurysm mimicking gastrointestinal tract bleeding

Hemobilia, a rare form of upper gastrointestinal bleeding (UGIB), is a potentially fatal complication that usually occurs after iatrogenic hepatobiliary trauma. However, hemobilia is clinically challenging to diagnose and often gets too late to diagnose. We herein report a case of recurrent hemobilia due to hepatic artery pseudoaneurysm (HAP) that was initially misdiagnosed as gastrointestinal tract bleeding. However, the patient was treated successfully with percutaneous coil occlusion of the pseudoaneurysm. This case illustrates that hemobilia can present as a mimic of gastrointestinal tract bleeding, but this is often difficult to diagnose at first glance and often misleads clinicians, especially emergency physicians, into making an incorrect diagnosis. Familiarity with the clinical features of hemobilia can help raise clinical suspicion and facilitate the early diagnosis and treatment of hemobilia.

Role of the endoscopic Doppler probe in nonvariceal upper gastrointestinal bleeding: Systematic review and meta-analysis

OBJECTIVES

The effectiveness of the Doppler endoscopic probe (DEP) remains unclear in nonvariceal upper gastrointestinal bleeding (NVUGIB). We thus performed a systematic review characterizing the effectiveness of DEP in patients with NVUGIB addressing this question.

METHODS

A literature search was done until July 2021 using MEDLINE, EMBASE, and ISI Web of Science. A series of meta-analyses were performed assessing outcomes among observational and interventional studies for DEP signal positive and negative lesions as well as DEP-assisted versus standard endoscopies. The primary outcome was "overall rebleeding"; secondary outcomes included all-cause mortality, bleeding-related mortality, need for surgery, length of stay, intensive care unit stay, and angiography.

RESULTS

Fourteen studies were included from 1911 citations identified. Observational studies compared bleeding lesions with DEP-positive versus DEP-negative signals (11 studies, n = 800 prehemostasis; five studies, n = 148 with posthemostasis data). Three interventional studies (n = 308) compared DEP-assisted to standard endoscopy management. DEP signal positive versus negative lesions either prior to or following any possible hemostasis were at greater risk of overall rebleeding (odds ratio [OR] 6.54 [2.36, 18.11] and OR 25.96 [6.74, 100.0], respectively). The use of DEP during upper endoscopy significantly reduced overall rebleeding rates (OR 0.27 [0.14, 0.54]). When removing outcomes analysis for which only one study was available, all evaluable outcomes were improved with DEP characterization of management guidance except for all-cause mortality.

CONCLUSION

Although with low certainty evidence, DEP-related information improves on sole visual prediction of rebleeding in NVUGIB, with DEP-guided management yielding decreased overall rebleeding, bleeding-related mortality, and need for surgery.

Case report: Aortoesophageal fistula-an extremely rare but life-threatening cardiovascular cause of hematemesis

Aortoesophageal fistula (AEF) is an extremely rare cardiovascular etiology of hematemesis and upper gastrointestinal bleeding. As such, its recognition and diagnosis are challenging and may be delayed when such patients present to the emergency department (ED). Without timely surgical intervention, AEF is almost always fatal. Awareness of AEF as a possible diagnosis and consequently early identification of these patients presenting to the ED are therefore crucial in optimizing clinical outcomes. We report a 45-year-old male presenting to the ED with the classical triad of an AEF (Chiari's triad)-midthoracic pain or dysphagia, a sentinel episode of minor hematemesis, then massive hematemesis with risk of exsanguination. The case report highlights the importance of considering the differential diagnosis of AEF when evaluating patients presenting to the ED with hematemesis, especially if they have predisposing risk factors such as prior aortic or esophageal surgeries, aortic aneurysms, or thoracic malignancies. Patients suspected of having AEF should be prioritized for early computed tomography angiography to expedite diagnosis and treatment.

Multidisciplinary treatment for acute massive upper gastrointestinal bleeding secondary to post-burn stress in a paediatric patient: a case report

BACKGROUND

Severe burns can readily induce gastric and duodenal mucosal erosions and superficial ulcers. In severe cases, haemorrhage or perforation of peptic ulcers might occur, threatening the lives of patients. At present, gastrointestinal haemorrhage after burns is treated mainly with drugs and gastrointestinal endoscopy. However, multidisciplinary treatment of gastroscopy combined with vascular embolization is rare.

CASE

A boy aged 3 years and 4 months was admitted to the hospital, scalded by boiling water on multiple parts of the body. On the 8th day after the injury, the patient continuously produced a large amount of tarry black stool, and the faecal occult blood test was positive. Haemostatic drug treatment was ineffective, and severe shock and disseminated intravascular coagulation (DIC) occurred. Under the guidance of a multidisciplinary team (MDT), a gastroscopy examination was performed and showed bleeding from a duodenal bulb ulcer. Due to a small intestinal lumen and thin intestinal wall, bleeding could not be controlled by gastroscopy. However, the bleeding point was clarified by gastroscopy and then gastroduodenal artery embolization was performed efficiently. No active gastrointestinal bleeding was observed after the surgery. The patient was followed for 6 months after discharge, and no gastrointestinal haemorrhage recurred.

CONCLUSIONS

This is a rare case of acute massive upper gastrointestinal bleeding secondary to post-burn stress in paediatric patients. For paediatric patients who cannot be treated by endoscopy, transcatheter embolization may be safer and more effective for achieving haemostasis. Through the collaboration of the MDT, gastroscopy combined with interventional embolization was performed, which successfully stopped the massive bleeding and saved the child`s life, making it worthy of clinical reference.
