BRBPR: Bright Red Blood Per Rectum
BRBPR stands for "Bright Red Blood Per Rectum" in medical terminology 1.
Definition and Clinical Significance
BRBPR refers to the passage of bright or dark red blood per rectum, which may present as:
- Blood on toilet paper after wiping
- Blood in the toilet bowl
- Blood mixed with stool
- Clots per rectum
This is a key presenting symptom of lower gastrointestinal bleeding (LGIB), which the British Society of Gastroenterology guidelines specifically define as including patients who present with bright or dark red blood per rectum 1.
Clinical Context
Important Diagnostic Considerations
While BRBPR typically indicates a lower GI source of bleeding, clinicians must recognize critical exceptions:
- Brisk upper GI bleeding can present as BRBPR when bleeding is rapid enough that blood doesn't undergo digestion 1
- Patients with BRBPR and hemodynamic instability may actually have an upper GI source 1
- Risk factors suggesting upper GI origin despite BRBPR include: peptic ulcer disease history, portal hypertension, elevated BUN/creatinine ratio, and antiplatelet drug use 1
Common Etiologies
The most frequent causes of BRBPR include:
- Hemorrhoids (most common at 54.2%)
- Anal fissures (14.2%)
- Inflammatory bowel disease
- Diverticular bleeding
- Colorectal neoplasms 2
Diagnostic Yield
In young adults (≤40 years) with BRBPR, the diagnostic yield of colonoscopy is 22%, significantly higher than the 11% yield in those without BRBPR 3. Serious pathology including inflammatory bowel disease (15%), advanced adenomas, and colorectal cancer (4%) can be identified 3.
The term BRBPR is widely used in clinical documentation and communication to quickly convey the nature of rectal bleeding presentation, which guides subsequent diagnostic and therapeutic decision-making.
