The solitary salp produces in its interior a little stolon or diverticulum which contains an outgrowth from the circulatory system, and this stolon gradually becomes pinched off into the members of the chain of the aggregate form.
"Thomas Henry Huxley; A Sketch Of His Life And Work"
P. Chalmers Mitchell
To determine the position and size of a diverticulum, a radiogram is taken after the patient has swallowed some food, such as porridge mixed with bismuth.

Should the diverticulum be inaccessible from the neck, and the difficulty of swallowing be attended with progressive emaciation, gastrostomy may be required to avert death by starvation.
