The Rovsing sign is a clinical examination finding used to help diagnose appendicitis. It is positive when pressure on the left lower abdomen causes pain in the right lower abdomen.
What is the Rovsing Sign?
The Rovsing sign (also called Rovsing symptom) is a clinical examination finding used during physical assessment of the abdomen. It is primarily used to support the diagnosis of appendicitis (inflammation of the appendix). The sign is named after the Danish surgeon Niels Thorkild Rovsing (1862–1927), who first described it.
The sign is considered positive when applying pressure to the left lower abdomen produces pain in the right lower abdomen, near the McBurney point. This response suggests irritation or inflammation of the appendix (vermiform appendix).
How is the Rovsing Sign Tested?
The test is performed as part of the clinical abdominal examination. The examiner uses a flat hand to apply slow, steady pressure to the left lower abdomen in the direction of the sigmoid colon. This causes a retrograde displacement of gas and bowel contents through the large intestine. If this maneuver produces pain in the right lower abdomen, the sign is considered positive.
Step-by-Step Technique
- The patient lies relaxed in the supine position.
- The examiner stands to the right of the patient.
- The right hand is used to slowly compress the left lower abdomen toward the sigmoid region.
- Positive result: the patient reports pain in the right lower abdomen (appendix region).
Clinical Significance
The Rovsing sign is one of several clinical signs evaluated when acute appendicitis is suspected. It is not a standalone diagnostic criterion but is always interpreted alongside other findings:
- McBurney point tenderness (point between the navel and right iliac crest)
- Rebound tenderness (Blumberg sign): pain upon sudden release of deep pressure
- Psoas sign: pain when raising the right leg against resistance
- Laboratory values: elevated inflammatory markers such as CRP and white blood cell count
- Imaging: abdominal ultrasound or CT scan
A positive Rovsing sign increases the likelihood of appendicitis, but a negative result does not rule it out. The sensitivity and specificity of the sign are limited and vary across studies.
Causes and Pathophysiology
The Rovsing sign is explained by the transmission of pressure through the colon. In the case of an inflamed appendix, the retrograde displacement of bowel contents and gas increases tension in the cecum and appendix. This irritates the inflamed mucosa and surrounding peritoneum, triggering the characteristic pain in the right lower abdomen.
Diagnosis of Appendicitis
The diagnosis of acute appendicitis relies on multiple pillars. Clinical scoring systems such as the Alvarado score or the Appendicitis Inflammatory Response (AIR) score combine symptoms, physical examination findings, and laboratory values to estimate diagnostic probability. The Rovsing sign is included as a clinical criterion in some of these scoring tools.
Diagnostic Tools at a Glance
- Physical examination (including Rovsing, Blumberg, and psoas signs)
- Blood count and inflammatory markers (CRP, leukocytes)
- Urinalysis (to rule out urinary tract infection)
- Abdominal ultrasound
- CT scan of the abdomen in unclear cases
Treatment of Appendicitis
In confirmed acute appendicitis, the standard treatment is surgical removal of the appendix (appendectomy), most commonly performed laparoscopically (minimally invasive). In early, uncomplicated cases, conservative antibiotic therapy may be considered, though the risk of recurrence is higher. In cases of perforation or peritonitis, surgical intervention is mandatory.
When to Seek Medical Attention?
Medical attention should be sought immediately if the following symptoms occur:
- Severe, persistent pain in the right lower abdomen
- Pain that worsens with movement or jarring
- Nausea, vomiting, and fever in combination with abdominal pain
- Rigid, board-like abdomen (possible sign of peritonitis)
