Rovsing Sign

What is the Rovsing sign?

The Rovsing sign is a physical examination finding where palpation of the left lower quadrant elicits pain in the right lower quadrant. This phenomenon indicates localized peritoneal irritation, most commonly associated with appendicitis. When interpreted alongside other findings, such as guarding and right lower quadrant tenderness, a Rovsing sign can increase suspicion for appendicitis or another intra-abdominal process. Identifying these cues promptly is vital for preventing complications like perforation or abscess formation.

What causes a positive Rovsing sign?

It is theorized that the sign occurs when pressure is applied to the left side of the abdomen because it displaces colonic gas and fluid toward the cecum. This shift theoretically stretches the inflamed parietal peritoneum overlying the appendix, triggering a somatic pain response. While the primary association is appendicitis, other causes of right lower quadrant peritoneal irritation can produce a similar finding.

The mechanism relies on the fact that the peritoneum becomes highly sensitive to any movement or distension when inflamed. This irritation explains why tenderness in the abdomen may be felt in the right lower quadrant even when the initial stimulus is on the left. If the inflammation is severe, such as in perforated cases, the response becomes more pronounced.

What are the signs and symptoms associated with a positive Rovsing sign?

Individuals with a positive Rovsing sign often have symptoms consistent with appendicitis, including pain that begins in the periumbilical region and later localizes to the right lower quadrant. Systemic features like a mild fever, tachycardia, and anorexia often accompany the physical findings. When the inflammatory process involves the nearby musculature, providers may also elicit a positive psoas or obturator sign.

The psoas test involves extending the patient’s right hip, while the obturator sign is pain triggered by internal rotation of the flexed right hip. These maneuvers, alongside tenderness in the abdomen, may support the clinical suspicion of appendicitis and can sometimes suggest a pelvic or retrocecal appendix, but they are not definitive. If the examiner notes a generalized tenderness, they must consider the possibility of widespread peritonitis.

How is the Rovsing sign assessed?

To perform the maneuver, the clinician applies firm, steady pressure to the left lower quadrant. The original description involved deep palpation with an upward sliding motion along the descending colon toward the splenic flexure. A positive Rovsing sign is present when a left-sided abdominal maneuver elicits pain in the right lower quadrant. This maneuver is used as an indirect bedside sign of right lower quadrant peritoneal irritation without initially palpating the most tender area. It complements other parts of the physical exam, such as checking for tenderness directly over McBurney’s point.

How is appendicitis treated?

Treatment focuses on resolving the underlying source of the peritoneal irritation, which is typically acute appendicitis. Once appendicitis is diagnosed, urgent surgical evaluation is required. Treatment usually involves appendectomy, although selected uncomplicated cases may be managed nonoperatively with antibiotics. Prior to surgery, clinicians initiate fluid resuscitation, analgesics for pain control, and intravenous antibiotics.

For individuals presenting with acute appendicitis complicated by a localized abscess, surgeons may opt for percutaneous drainage first. In these scenarios, the appendectomy is often delayed until the initial inflammation subsides. Continuous monitoring of the patient’s vitals and abdominal status ensures that the treatment plan effectively halts the progression of the infection.

What are the most important facts to know about the Rovsing sign?

• Rovsing sign occurs when pressing on the left side of the abdomen causes pain on the right, indicating peritoneal irritation.
• The maneuver is a supportive bedside finding in suspected appendicitis, but it is neither sensitive nor specific enough to confirm the diagnosis alone.
• Clinicians use Rovsing’s sign, alongside right lower quadrant tenderness, guarding, the psoas test, and the obturator sign, to support bedside assessment.
• Rebound tenderness suggests that the inflammatory process has reached the parietal peritoneum.
• A positive Rovsing sign should prompt further evaluation for acute appendicitis and other causes of right lower quadrant peritoneal irritation.
