Where should ascitic drains be placed? Revisiting anatomical landmarks for paracentesis
We welcome the recent publication of the BSG/BASL guidelines on the management of ascites in cirrhosis which will serve as a framework for patient management across the world.1 Following clinician feedback on Twitter,2 we wish to respectfully highlight concerns regarding their guidance on landmarks for therapeutic paracentesis. Our first concern relates to the description of the landmarks.
