Operation Definition
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, Left
The left large intestine comprises the descending colon and splenic flexure region, and this value is used when resection extends across this left-sided segment rather than being confined to a single more specific structure such as the descending or sigmoid colon alone. Left colon resections are performed for splenic flexure or descending colon carcinoma, diverticular disease with stricture or fistula, or ischemic colitis affecting the watershed area near the splenic flexure, which is particularly vulnerable to reduced perfusion. Mobilization often requires taking down the splenic flexure attachments to achieve a tension-free anastomosis, and the proximity to the spleen means surgeons must take care to avoid capsular injury during dissection. The operative report should be reviewed to confirm the resection genuinely spans this left-sided territory rather than a single named subsegment.
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.
Qualifier: Hand-Assisted
This qualifier indicates that a laparoscopic or endoscopic procedure was performed with the surgeon's hand inserted through a separate incision to provide tactile feedback and manual assistance alongside the instruments. It distinguishes hand-assisted minimally invasive technique from standard laparoscopic approaches performed with instruments alone.
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.
