title: Fundamentals of liver surgery for the practicing general surgeon.
abstract: This review focuses on the common general surgical referral problem of an undefined liver lesion. Understanding the clinical context in which the patient presents allows one to narrow the differential diagnosis and develop a focused evaluation plan. Most often, MRI is the most helpful initial study to define the likely diagnosis. If the appropriate radiologic expertise exists locally, most of the diagnostic evaluation, if not all, is feasible by a practicing general surgeon. Likewise, understanding the fundamentals of liver anatomy and physiology will facilitate the general surgeons' ability to evaluate the patient's imaging and liver reserve to decide whether local surgical care can be done safely. If local care is not available or safe, referral to a hepatobiliary specialist is appropriate. Ultimately, it is most important for the general surgeon contemplating surgery on the liver to understand his or her own limitations and the limits of their institutions' capabilities in providing pre- and postoperative care. It is particularly important to understand the pitfalls associated with decision-making for complex hepatobiliary problems and when considering an operation on anybody with significant intrinsic liver disease. When faced with these scenarios, the practicing general surgeon should always raise the question: "Is this patient better served at a hepatobiliary center or one that offers liver transplant?" If yes, a phone call, if not a referral, to a tertiary center to discuss the case is reasonable before embarking on a potentially hazardous operation.
