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, Right Lobe
The right lobe of the liver is the larger of the two anatomic lobes, supplied by the right hepatic artery and right portal vein branch and drained by the right hepatic vein, and it is the more common site of primary hepatocellular carcinoma, large metastatic deposits, and hydatid cysts because of its greater parenchymal volume. A right hepatectomy removes this entire lobe along Cantlie's line, requiring individual ligation of the right hepatic artery, right portal vein, right hepatic duct, and right hepatic vein before parenchymal transection. Because the remaining left lobe must hypertrophy to sustain synthetic and metabolic function, preoperative volumetric assessment and sometimes portal vein embolization precede the procedure. Coding as Resection reflects that no portion of right lobe tissue remains, distinguishing it from a partial right-sided excision or segmentectomy.
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
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.
