Case 93: Multidirectional Rotation of the Biopsy Needle for Better Sampling - Left Para-Aortic Retroperitoneal Node Biopsy

This 86-years old, treated earlier for endometrial carcinoma presented with lung, skeletal and nodal lesions. A biopsy of one of the retroperitoneal nodes was requested.

I have used this case to highlight how I sample different parts of the tumor by rotating the biopsy gun in different directions. This is a process I use daily in almost all biopsies, often combined with other techniques such as angulating the needle, tilting the needle or bending the needle.

Shout-out to #evacularrounds who mentioned this a few months ago, though I prefer the term multidirectional rotation to "flipping".

The video explains the rest.
