Cutting out or off, without replacement, all of a body part
Procedure Overview
Resection covers the complete removal of an entire lymphatic or hemic body part, without replacing it, and is one of the more consequential procedure types in this family because it permanently eliminates that structure. The most familiar example is total splenectomy, removing the entire spleen after severe trauma, certain blood disorders, or an enlarged spleen that is failing or at risk of rupture. Other examples include complete thymectomy for thymic tumors or myasthenia gravis, and full lymphadenectomy, where an entire chain or region of lymph nodes is removed, often as part of cancer staging or treatment to prevent disease spread.
Because these organs and nodes support immune defense and fluid balance, patients undergoing resection are usually counseled about the tradeoffs, such as increased infection risk after splenectomy, before the procedure is performed.
Anatomy & Axis Detail
Thoracic Duct
The thoracic duct is the body's largest lymphatic vessel, running from the cisterna chyli in the abdomen up through the chest to empty into the venous system near the left subclavian vein, and it carries the bulk of the body's lymph and dietary fat. Resection of the thoracic duct is uncommon and usually reserved for tumor invasion, traumatic injury with uncontrollable chylous leakage, or a duct that has been irreparably damaged during another thoracic operation. Because it drains lymph from nearly the entire body below the diaphragm and the left side above it, removing a segment risks chylothorax or persistent lymphatic leakage if collateral drainage does not compensate. Surgeons performing this resection often ligate the duct proximally and distally before removing the affected segment, and the operative note should confirm that a portion of the duct itself, not surrounding nodal tissue, was excised.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Coding & Documentation
Documentation must clearly state that the entire body part was removed, not a portion of it, since removing only part of an organ or only some nodes in a chain is coded as Excision rather than Resection. This distinction is one of the most frequent sources of coding errors in this family, especially with lymphadenectomies, where a note describing removal of "regional lymph nodes" needs to specify whether the entire nodal chain or basin was taken versus a sampling of nodes. Coders also need to confirm the specific body part value that matches the region resected, such as spleen versus a named lymph node group, and should check whether any adjacent structures were resected in the same operation, which would require additional codes.
