What to expect during Sentinel Node/Lymph Node Dissection
Sentinel Node/Lymph Node Dissection is a surgical procedure used to remove lymph nodes from various areas of the body for the purpose of detecting or treating cancer. The surgeon makes an incision and uses a combination of instruments to locate and remove the nodes, which are then sent to the lab for analysis. Methylene blue may be injected before the surgery to make the nodes easier to locate. Understanding the steps involved and the instruments used can help surgical technologists better assist the surgeon and ensure a successful outcome for the patient.

Step 1: Incision and Dissection
During a Sentinel Node/Lymph Node Dissection, the surgeon will make an incision with a 15 blade loaded on a #3 knife handle. They will then dissect down to the nodes using instruments such as metz, debakeys, and a tonsil. The surgeon may also use skin hooks or army-navys for retraction, depending on the depth of the dissection.
Step 2: Specimen Collection
Once the nodes have been located, the surgeon will collect the specimens using a combination of forceps and scissors. These specimens will then be sent to the lab for analysis to determine if there is any cancer present. Depending on the surgeon’s preference, they may choose to close the incision before receiving the lab results.
Step 3: Methylene Blue Injection
To make the nodes easier to locate, methylene blue may be injected prior to the start of the surgery. This can be done either unsterile or sterile, depending on the surgeon’s preference. A probe may also be draped and used to assist in finding the nodes.
The Surgery Sparknotes
- Make incision and dissect using 15 blade, metz, debakeys, and tonsil. Use skin hooks or army-navys for retraction.
- Collect specimens using forceps and scissors. Send to lab for analysis.
- Inject methylene blue before surgery to locate nodes. Use sterile or unsterile technique. Use a probe if necessary.
