T-tube elevation height

Lift the T-tube from the edge of the bed to the bedside infusion stand. The height is generally 20 ~ 30cm from the horizontal line cut by the common bile duct to the highest point of the raised drainage tube.

T-tube drainage, as the basic operation of traditional biliary surgery, has gradually decreased in clinic with the continuous development of modern surgery and medical imaging, but it is still an indispensable basic treatment method in clinic. As a continuous drainage after choledochotomy, T-tube drainage undertakes the treatment and safety measures. For many years, natural gravity drainage after T-tube drainage has enabled most patients to recover.
