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
Stomach
Resection of the stomach removes part or all of this saccular organ responsible for acid digestion and initial food breakdown, performed most often for gastric adenocarcinoma, refractory peptic ulcer disease, or severe, uncontrolled bleeding or perforation. The stomach's rich, overlapping blood supply from the left and right gastric, gastroepiploic, and short gastric arteries allows surgeons to ligate several vessels while preserving adequate perfusion to the remaining stomach, a flexibility not shared by more vascularly vulnerable organs. Because the stomach's proximal and distal ends interface with the esophagus and duodenum respectively, resection extent, whether partial, subtotal, or total, determines what reconstruction is needed to restore gastrointestinal continuity, such as gastrojejunostomy after distal resection. Total gastrectomy eliminates intrinsic factor production, with downstream implications for vitamin B12 absorption that are relevant to postoperative management though separate from the resection coding itself.
Approach: Via Natural or Artificial Opening Endoscopic
Via Natural or Artificial Opening Endoscopic describes instrumentation introduced through a natural orifice or a surgically created opening while using an endoscope for visualization, as in a routine colonoscopy performed through the anus. It differs from the plain Via Natural or Artificial Opening value by the added scope, and from Percutaneous Endoscopic by using an existing passage rather than a new skin puncture.
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.
