Procedure Overview
Resection covers the complete removal of a hepatobiliary or pancreatic organ or anatomically distinct portion, without replacing it with a graft or device. The most familiar example is cholecystectomy, the complete removal of the gallbladder, typically performed for symptomatic gallstones, chronic inflammation, or gallbladder cancer. Other examples include total pancreatectomy and complete removal of an anatomically whole lobe of the liver when disease affects the entire segment.
These procedures are chosen when disease, such as cancer, severe infection, or irreversible organ damage, involves an entire anatomically distinct body part and leaving any of it behind would not resolve the underlying problem. Because the liver and pancreas perform essential metabolic and digestive functions, surgeons carefully weigh how much can be safely removed before turning to resection of a whole part rather than a partial excision.
Anatomy & Axis Detail
Hepatic Duct, Left
The left hepatic duct collects bile from the left lobe and unites with the right hepatic duct to form the common hepatic duct, but it typically has a longer extrahepatic course than its right-sided counterpart, which can make it more accessible surgically yet also more exposed to injury during hepatobiliary procedures. It is resected for cholangiocarcinoma centered on the left system, high strictures from primary sclerosing cholangitis, or as part of a left hepatectomy when tumor extends along the ductal confluence. Because bile flow from the left lobe must be re-established afterward, resection is usually paired with hepaticojejunostomy reconstruction. The Resection code applies specifically to complete excision of this ductal segment without a synthetic or biologic device used to replace it in place.
Approach: Via Natural or Artificial Opening
Via Natural or Artificial Opening means the instrument reaches the target site by passing through an existing body orifice, such as the mouth or urethra, or a surgically created opening like a stoma, without additional incision or scope guidance. It is distinguished from the Endoscopic variant by the absence of a visualizing scope, and from External by actually traversing into the body through that opening.
Coding & Documentation
For Resection to apply, the documentation must show that an entire anatomically distinct body part, such as the whole gallbladder, an entire hepatic lobe, or the whole pancreas, was removed, not just a margin or lesion. When only a portion of an organ is taken, such as a wedge of liver tissue or the pancreatic tail alone, the case should instead be coded as an excision, a distinction that trips up coders regularly. Pathology and operative reports should be cross-referenced to confirm the full extent of what was removed and whether any organ tissue remained in the patient.
