Revolutionizing the assessment of patients with abdominal pain

PERIsign: A revolutionizing diagnostic aid for the emergency department

STB INN is developing PERIsign™. A revolutionizing diagnostic aid for the emergency department. Within minutes, PERIsign evaluates patients with abdominal pain and determines if they require further investigations, medical treatment, surgery, or is safe to go home.

Challenges diagnosing one of the most common causes of ED visits

Acute abdominal pain accounts for about 10 % of all Emergency Department (ED) visits worldwide. In the US and Europe combined, more than 23 million patients visit the ED due to acute abdominal pain each year. Currently, these patients are assessed by hand through palpation.

1/4 misdiagnosed

Even in experienced hands, the manual palpation of patients leads to misdiagnosis in one fourth of patients with abdominal pain

Long waiting times

The ED is often staffed with junior doctors. Inexperience results in long waiting times as patients have to await additional assessment

Ineffective use of resources

Overcrowding, unnecessary admissions, and  overutilization of advanced equipment contribute to ineffective use of healthcare resources

The solution: PERIsign

PERIsign is a novel medical device that aid the healthcare professional to make a fast, objective, and correct assessment of patients with acute abdominal pain. Currently, these assessments are subjective, uncertain and highly dependent on the experience of the examiner.

Cost effective

Within minutes, PERIsign detects if the patient suffers from peritonitis – the physiological response to severe intraabdominal illness


PERIsign replaces subjective and difficult manual palpation with an objective and easily acquired measurement that can be performed early in the workflow
