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
Liver
The liver is the body's largest solid organ, organized into functionally distinct lobes and segments defined by portal and hepatic venous branching, and it performs essential metabolic, synthetic, and detoxification functions. Resection of the liver ranges from removal of a small wedge of parenchyma to major anatomic lobectomy, most commonly performed for primary or metastatic liver tumors, but also for benign masses, trauma, or living-donor transplantation, and the extent of resection is typically planned around the segmental anatomy to preserve adequate functional liver mass and vascular inflow and outflow to the remaining tissue. Because the liver has substantial regenerative capacity, larger resections are often tolerated, but documentation should specify whether the procedure removed a defined segment, lobe, or only a portion of the organ, since this affects both coding precision and clinical risk assessment.
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
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.
