Cutting out or off, without replacement, all of a body part
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
Large Intestine, Right
The right large intestine encompasses the cecum, ascending colon, and hepatic flexure, and this body part value is used when the resection spans this region as a defined right-sided segment rather than being localized to a single named substructure. Right-sided colon resections are most often performed for cecal or ascending colon adenocarcinoma, cecal volvulus, or complicated appendicitis extending into the cecum, and the specimen typically includes the terminal ileum and ileocecal valve along with the mesenteric lymph nodes draining this territory given the shared blood supply from the ileocolic and right colic vessels. Because a right colectomy inherently disrupts the ileocecal junction, postoperative bowel habits tend to be looser than after left-sided resections. The operative note should clarify whether the resection was confined to a single labeled segment or genuinely spans the right colon as documented here.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
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.
