Rovsing Sign (1907)
The Rovsing sign is described variably in medical literature with most descriptions bearing little/no resemblance to the 1907 description by Rovsing, but rather the description offered by Perman in 1904.
This sign is commonly taught to be attributable to eliciting peritoneal irritation, Rovsing’s original description and intention were quite different. Rovsing originally described the manoeuvre as an attempt to distend the caecum and appendix by applying pressure to the left colon, in an anti-peristaltic fashion.
I press with my right hand onto the fingers of the left hand that is lying flat against the colon descendens [descending colon] and then let the hand glide up toward the splenic flexure…The entire method is based upon isolated rise of pressure within the colon.Rovsing 1907
In doing this correctly, Rovsing suggests that if pain is elicited, then this isolates the source to the caecum or appendix, and rules out other structures in the right iliac fossa.
2014 – Prosenz et al reviewed 1178 individual studies and found no included study correctly described the method of eliciting Rovsing sign. Of 9 textbooks reviewed, 3 English texts on surgery failed to described the sign accurately, however all 6 German (text)books provided an accurate description.
- Rovsing Operation I (1910) procedure for decortication in polycystic kidney disease
- Rovsing Syndrome (1911) umbilical pain in horseshoe kidney caused by vascular compression, enhanced by dorsal flexion of the lumbar vertebrae
- Rovsing Operation II (1911) to separate a fused horseshoe kidney via division of the renal isthmus
- Male to female sex reassignment surgery (1918) according to Rovsing, the first of its kind
1890 Rovsing was dismissed from role as Junior Surgeon at Royal Frederiks Hospital when he married, as he was appointed as an ‘unmarried junior surgeon’. The dismissal received national attention, leading to other doctors striking, and five months later Rovsing was reinstated as a ‘married junior surgeon’.

Als Rovsing-Zeichen (nach Niels Thorkild Rovsing, dänischer Chirurg, 1862 bis 1927) bezeichnet man die bei einer Appendizitis („Blinddarmentzündung“) im Bereich des rechten Unterbauchs auslösbaren Schmerzen, die durch das rückwärts gerichtete Ausstreichen des Dickdarms (Colon) gegen den Uhrzeigersinn (zum Wurmfortsatz hin) entstehen. Das Auslösen des Rovsing-Zeichens ist nicht spezifisch für die Appendizitis, ebenso wenig wie die Nicht-Auslösbarkeit eine solche ausschließt. Das Zeichen ist daher nur im Kontext mit anderen klinischen Befunden zu verwerten.
Aufgrund der Gefahr einer Verschlimmerung der Entzündung oder Perforation wird empfohlen, diesen Test nicht mehr durchzuführen.
