Lymph Node Biopsy

Lymph Node Biopsy - Guillotine TechniqueLymph Node Biopsy - Guillotine TechniqueLymph node biopsies can be obtained by cutting out a wedge of tissue and suturing the cut edges of the defect or with the ‘guillotine’ method. Removal of an entire lymph node is also possible. Lymph nodes are typically vascular and often located close to important structures such as mesenteric vessels, etc. For these reasons, I prefer to gently dissect a pole of the chosen lymph node (by removing the thin layer of mesentery), and perform a ‘guillotine’ biopsy as described in the liver biopsy section. I use 4-0 or 3-0 absorbable suture for lymph node biopsies.
