Abstract
BACKGROUND/AIMS Upper gastrointestinal bleeding (UGIB) is a life-threatening condition that necessitates early identification and intervention and is associated with substantial morbidity, mortality, and socioeconomic burden. However, several diagnostic challenges remain regarding risk stratification and the optimal timing of endoscopy. The PillSense System is a noninvasive device developed to detect blood in patients with UGIB in real time. This study aimed to assess the safety and performance characteristics of PillSense using a simulated bleeding model. METHODS A preclinical study was performed using an in vivo porcine model (14 animals). Fourteen PillSense capsules were endoscopically placed in the stomach and blood was injected into the stomach to simulate bleeding. The safety and sensitivity of blood detection and pill excretion were also investigated. RESULTS All the sensors successfully detected the presence or absence of blood. The minimum threshold was 9% blood concentration, with additional detection of increasing concentrations of up to 22.5% blood. All the sensors passed naturally through the gastrointestinal tract. CONCLUSION This study demonstrated the ability of the PillSense System sensor to detect UGIB across a wide range of blood concentrations. This ingestible device detects UGIB in real time and has the potential to be an effective tool to supplement the current standard of care. These favorable results will be further investigated in future clinical studies.

Risk stratification with video capsule endoscopy leads to fewer hospital admissions in emergency department patients with low-risk to moderate-risk upper gastrointestinal bleed: A multicenter clinical trial. J Am Coll Emerg Physicians Open 2021; 2:e12579. [PMID: 34723247 PMCID: PMC8544929 DOI: 10.1002/emp2.12579] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 10/01/2021] [Accepted: 10/01/2021] [Indexed: 12/12/2022] Open
Abstract
OBJECTIVE In US emergency departments (EDs), the physician has limited ability to evaluate for common and serious conditions of the gastrointestinal (GI) mucosa such as a bleeding peptic ulcer. Although many bleeding lesions are self-limited, the majority of these patients require emergency hospitalization for upper endoscopy (EGD). We conducted a clinical trial to determine if ED risk stratification with video capsule endoscopy (VCE) reduces hospitalization rates for low-risk to moderate-risk patients with suspected upper GI bleeding. METHODS We conducted a randomized controlled trial at 3 urban academic EDs. Inclusion criteria included signs of upper GI bleeding and a Glasgow Blatchford score <6. Patients were randomly assigned to 1 of the following 2 treatment arms: (1) an experimental arm that included VCE risk stratification and brief ED observation versus (2) a standard care arm that included admission for inpatient EGD. The primary outcome was hospital admission. Patients were followed for 7 and 30 days to assess for rebleeding events and revisits to the hospital. RESULTS The trial was terminated early as a result of low accrual. The trial was also terminated early because of a need to repurpose all staff to respond to the coronavirus disease 2019 pandemic. A total of 24 patients were enrolled in the study. In the experimental group, 2/11 (18.2%) patients were admitted to the hospital, and in the standard of care group, 10/13 (76.9%) patients were admitted to the hospital (P = 0.012). There was no difference in safety on day 7 and day 30 after the index ED visit. CONCLUSIONS VCE is a potential strategy to decrease admissions for upper GI bleeding, though further study with a larger cohort is required before this approach can be recommended.

Abstract
Video capsule endoscopy has been proven to be a beneficial tool to inspect the gastrointestinal lumen but its true impact may lie in utilization outside of traditional gastroenterology settings such as in the emergency room, the intensive care unit, and outpatient settings. Some advantages of video capsule endoscopy are that its administration does not require special training, patients do not require anesthesia, and videos can be shared with off-site consultants.

Abstract
The development of video capsule endoscopy (VCE) has allowed for visualization of parts of the gastrointestinal tract generally not readily accessible by noninvasive means. Its ease of use has proved useful in diagnosing and managing various small bowel inflammatory disorders. Continued technological evolution of VCE has paved the way for use in small intestinal bleeding and in patients with acute gastrointestinal bleeding. A detailed analysis of costs associated with VCE has demonstrated its ability to promote efficient allocation of health care resources. Further work is needed regarding development of a universal infrastructure to handle the widespread use of VCE technology.

Abstract
BACKGROUND AND AIMS Acute upper GI bleeding is common and requires investigation with EGD, but endotherapy is not always necessary. Magnetically assisted capsule endoscopy (MACE) uses a capsule steerable by an external magnet and allows examination of the upper GI tract and small bowel, but its role in acute upper GI bleeding has not been assessed. METHODS We conducted a prospective cohort study comparing the diagnostic yield of MACE and EGD in patients with suspected acute upper GI bleeding. Patient tolerance, mucosal visibility by MACE, and frequency of small-bowel bleeding were assessed. Whether or not MACE could safely predict discharge of patients was also determined. RESULTS Thirty-three patients were included for analysis (median age, 60 years; 75.8% male). MACE detected more focal lesions (peptic, vascular, and fresh/altered blood without a clear source) than EGD (40 versus 25, respectively, P = .02) but statistical significance was not reached for significant lesions (considered to be the bleeding source; 14 vs 13, respectively, P = 1). Capsule endoscopy identified an additional cause for bleeding in the small bowel in 18%. Visualization by MACE was excellent in most areas; views of the esophagus, gastroesophageal junction, fundus, and duodenal bulb were suboptimal. MACE was better tolerated than unsedated EGD and correctly identified patients who were safe for discharge. CONCLUSIONS MACE had higher diagnostic yield for focal lesions and was better tolerated than EGD. It also correctly predicted safe discharge for patients with acute upper GI bleeding.

Abstract
Background and study aims Upper gastrointestinal bleeding (UGIB) is a frequent cause of hospitalization. Because of the lack of reliable noninvasive diagnostic tools, the decision to proceed with emergency endoscopy in these cases is made based on clinical parameters. A novel non-imaging telemetric real-time sensor capsule (HemoPill Acute, Ovesco Endoscopy AG) has shown promising results for noninvasive detection of UGIB in preclinical studies. Patients and methods We conducted a prospective non-randomized, single center, open-label study to investigate feasibility and safety of the novel sensor capsule in patients with symptoms of UGIB. The primary aim of the first clinical study was to investigate feasibility and safety of the device in a clinical setting. All patients underwent endoscopy within 12 hours after capsule ingestion. Sensor data from the capsule within 10 minutes after ingestion were compared with endoscopic findings. Results From April 2015 to February 2016, 30 consecutive patients with symptoms of acute UGIB were included; 27 were eligible for analysis. Capsule ingestion was well tolerated in all patients and there were no device-related adverse events. Endoscopy showed blood or hematin in the upper gastrointestinal tract of 10 of 27 patients; in 2 of 10 patients it was estimated to be more than 20 mL; in 4 of 8 patients it was between 5 and 20 mL and in 4 of 8 it was estimated to < 5 mL. The sensor capsule was positive in 2 of 2 patients (100 %) with > 20 mL of blood or hematin and in 1 of 8 patients (12.5 %) between 5 and 20 mL. All patients (17/17; 100 %) were correctly identified as non-bleeders. Conclusion Both device and procedure proved to be safe and feasible. Larger studies will be necessary to evaluate the role of the sensor capsule in risk stratification of patients with acute UGIB.

Abstract
BACKGROUND Acute upper gastrointestinal bleeding is a life-threatening medical condition with a relevant risk of re-bleeding even after initial endoscopic hemostasis. The implantable HemoPill monitor contains a novel telemetric sensor to optically detect blood in the stomach allowing the surveillance of high-risk patients for re-bleedings. METHODS In this pre-clinical porcine study, bleeding has been simulated by injecting porcine blood into the stomach of a pig through an implanted catheter using a syringe pump. The effect of the sensor position in the stomach, the gastric food content, and the bleeding intensity was investigated. RESULTS Sensitivity and specificity of the sensor reached more than 87.5% when the sensor was positioned close to the source of bleeding. Solid food had a higher negative impact on sensitivity than liquid food but a positive impact on specificity. A heavy bleeding was more likely to be detected by the sensor but was also associated with a lower likelihood for true-negative results than weaker bleedings. CONCLUSIONS The study clearly demonstrated the capability of the HemoPill sensor prototype to detect clinically relevant bleedings with high sensitivity and specificity (> 80%) when the sensor was positioned close to the bleeding site. The sensors proved to be robust against artefact effects from stomach content. These are favorable findings that underline the potential benefit for the use of the HemoPill sensor in monitoring patients with a risk of re-bleeding in the upper gastrointestinal tract.

Abstract
Non-variceal upper gastrointestinal bleeding remains an important emergency condition, leading to significant morbidity and mortality. As endoscopic therapy is the 'gold standard' of management, treatment of these patients can be considered in three stages: pre-endoscopic treatment, endoscopic haemostasis and post-endoscopic management. Since publication of the Asia-Pacific consensus on non-variceal upper gastrointestinal bleeding (NVUGIB) 7 years ago, there have been significant advancements in the clinical management of patients in all three stages. These include pre-endoscopy risk stratification scores, blood and platelet transfusion, use of proton pump inhibitors; during endoscopy new haemostasis techniques (haemostatic powder spray and over-the-scope clips); and post-endoscopy management by second-look endoscopy and medication strategies. Emerging techniques, including capsule endoscopy and Doppler endoscopic probe in assessing adequacy of endoscopic therapy, and the pre-emptive use of angiographic embolisation, are attracting new attention. An emerging problem is the increasing use of dual antiplatelet agents and direct oral anticoagulants in patients with cardiac and cerebrovascular diseases. Guidelines on the discontinuation and then resumption of these agents in patients presenting with NVUGIB are very much needed. The Asia-Pacific Working Group examined recent evidence and recommends practical management guidelines in this updated consensus statement.

Abstract
AIM To test the feasibility and performance of a novel upper gastrointestinal (GI) capsule endoscope using a nurse-led protocol.
METHODS We conducted a prospective cohort analysis of patients who declined gastroscopy (oesophagogastroduodenoscopy, OGD) but who consented to upper GI capsule endoscopy. Patients swallowed the upper GI capsule following ingestion of 1 liter of water (containing simethicone). A series of positional changes were used to exploit the effects of water flow and move the upper GI capsule from one gravity-dependent area to another using a nurse-led protocol. Capsule transit time, video reading time, mucosal visualisation, pathology detection and patient tolerance was evaluated.
RESULTS Fifty patients were included in the study. The mean capsule transit times in the oesophagus and stomach were 28 s and 68 min respectively. Visualisation of the following major anatomical landmarks was achieved (graded 1-5: Poor to excellent): Oesophagus, 4.8 (± 0.5); gastro-oesophageal junction (GOJ), 4.8 (± 0.8); cardia, 4.8 (± 0.8); fundus, 3.8 (± 1.2); body, 4.5 (± 1); antrum, 4.5 (± 1); pylorus, 4.7 (± 0.8); duodenal bulb, 4.7 (± 0.7); second part of the duodenum (D2), 4.7 (± 1). The upper GI capsule reached D2 in 64% of patients. The mean video reading time was 48 min with standard playback mode and 20 min using Quickview (P = 0.0001). No pathology was missed using Quickview. Procedural tolerance was excellent. No complications were seen with the upper GI capsule.
CONCLUSION The upper GI capsule achieved excellent views of the upper GI tract. Future studies should compare the diagnostic accuracy between upper GI capsule and OGD.

Abstract
Software tools have been developed as capsule endoscopy (CE) reading aids. The suspected blood indicator (SBI) tags possible areas of haemorrhage in the gastrointestinal (GI) tract. This meta-analysis aims to investigate the diagnostic accuracy of SBI in CE. Areas covered: A systematic literature search was conducted for studies on the use of SBI in CE. Sensitivity, specificity and diagnostic odds ratio (DOR) of SBI in diagnosing GI bleeding was evaluated. 2040 patients from 16 studies underwent 2049 CE examinations. The overall sensitivity of SBI for bleeding or potentially bleeding lesions was 0.553, specificity 0.578, DOR 12.354. The sensitivity of SBI for active bleeding was 0.988, specificity 0.646, DOR 229.89. Expert commentary: Currently, SBI has limited validity in CE reading. However, in active GI bleeding, it has good sensitivity, supporting its use in the acute setting.

Abstract
The established quality indicators for early management of upper gastrointestinal (GI) hemorrhage are based on rapid diagnosis, risk stratification, and early management. Effective preendoscopic treatment may improve survivability of critically ill patients and improve resource allocation for all patients. Accurate risk stratification helps determine the need for hospital admission, hemodynamic monitoring, blood transfusion, and endoscopic hemostasis before esophagogastroduodenoscopy (EGD) via indirect measures such as laboratory studies, physiologic data, and comorbidities. Early management before the definitive EGD is essential to improving outcomes for patients with upper GI bleeding.
