Lymph Node Yield After Specimen Fixation With Carnoy's Solution and 10% Neutral Buffered Formaldehyde in Patients With Colorectal Cancer or Gastric Adenocarcinoma Specimens: a Randomized Trial
This study evaluates the number of lymph nodes dissected in specimens following fixation with 10% neutral buffered formaldehyde or Carnoy's solution. Specimens were randomized for fixation in each solution.
Carnoy's solution is a tissue fixative that has alcohol allowing for fat clearing along with tissue fixation. Specimens were randomized after the surgical procedure. The perivisceral fat was removed from the stomach and the lymph node stations disected and then fixed in formalin or carnoy's solution for 24-48h. After dissection the residual fat from the formalin group was re-fixed in carnoy and re-disected.
