Run by Tan Tock Seng Hospital · NCT06500468 · Data updated 2026-11-12
This study is testing a new capsule that can quickly check for bleeding in the stomach to help emergency doctors decide if patients can go home or need more treatment.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 21 and older presenting with symptoms of acute overt upper gastrointestinal bleeding, such as coffee ground vomiting or melena.
✕Probably not a fit
Patients experiencing hemodynamic shock or those requiring urgent endoscopy or surgery will not benefit from this study.

What this trial studies
This study evaluates the efficacy and safety of the PillSense System, a novel blood-sensing capsule designed to help emergency doctors assess active upper gastrointestinal bleeding in patients. The PillSense Capsule is ingested by the patient and works in conjunction with an external monitor to provide real-time data on bleeding within 10 minutes. If no blood is detected, patients may be discharged safely, reducing their wait time in the emergency department. Conversely, if blood is detected, patients will be admitted for further evaluation and treatment. This approach aims to streamline patient management and improve overall hospital resource utilization.
Why it matters
Potential benefit: If successful, this system could significantly enhance the speed and accuracy of diagnosing upper gastrointestinal bleeding, leading to better patient outcomes.
How similar studies have gone: While the use of capsule endoscopy is established, this specific application of the PillSense System for rapid bleeding detection is novel and has not been extensively tested in prior studies.

Dysphagia, odynophagia, swallowing disorder, and/or Zenker's diverticulum, issues with the motility of the gastrointestinal tract, Crohn's disease, previous GI surgery, suspected ileus, bowel obstruction and/or perforation) * Patients with a known history of oesophageal or gastric varices * Patients with known UGI pathology (such as oesophageal/gastric cancer), or recent (within 3 months) upper GI ulcer bleeding, upper GI surgeries or procedures * Patients who are on anticoagulation * Patients with cardiac implantable electrical device (CIED) * Patients who had altered mental status * Pregnant and/or lactating women (Female patients below age 60, without history of hysterectomy or are not documented to be post-menopausal, will be given a urine pregnancy test to confirm they are not pregnant) * Patients who have an MRI investigation planned within 2 weeks
