Procedure Overview
Resection describes the surgical removal of an entire gastrointestinal organ or a clearly defined anatomic segment of one, without putting anything in its place. Common examples include total gastrectomy for stomach cancer, complete removal of the appendix, and total colectomy for severe ulcerative colitis, where the entire designated body part as defined by the coding system is taken out rather than just a portion of it.
Surgeons choose resection when disease, most often cancer, severe inflammatory conditions, or irreversible ischemic damage, affects an entire organ or a segment that the classification treats as a whole unit, such as the cecum or the sigmoid colon. The remaining ends of the digestive tract are typically reconnected in the same operation, restoring continuity, though in some cases a stoma is created instead when reconnection is not immediately safe.
Anatomy & Axis Detail
Esophagus
Resection of the esophagus as a whole, or esophagectomy, removes the entire muscular conduit connecting the pharynx to the stomach, undertaken most often for esophageal cancer spanning multiple segments, extensive Barrett's disease with high-grade dysplasia, or end-stage motility disorders such as achalasia unresponsive to other treatment. Because the esophagus lacks a serosal covering and traverses the neck, chest, and abdomen in close relation to the trachea, aorta, and both pleural cavities, total resection is among the most invasive gastrointestinal operations, typically performed through combined transthoracic, transhiatal, or minimally invasive multi-cavity approaches. Its segmental blood supply, without a single dominant artery, requires careful preservation of collateral flow to the remaining conduit. Total esophagectomy always requires reconstruction, most commonly gastric pull-up, to restore continuity between the pharynx and stomach.
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
The key documentation requirement is that the entire body part, as defined by the specific GI body part value, was removed, not merely a partial excision of tissue from within it. When only part of a segment is taken, such as a wedge of stomach tissue, the correct root operation is Excision rather than Resection, which is one of the most common assignment errors in this family. Coders must also identify whether an anastomosis, stoma, or other reconstruction was performed and code that separately from the resection itself, since the two are distinct steps. Clear identification of the specific segment removed, such as right colon versus left colon versus total colon, is essential because each maps to a different body part value.
