Role of laparoscopy in hepatobiliary malignancies

The many benefits of laparoscopy, including smaller incision, reduced length of hospital stay and more rapid return to normal function, have seen its popularity grow in recent years. With concurrent improvements in non-surgical cancer management the importance of accurate staging is becoming increasingly important. There are two main applications of laparoscopic surgery in managing hepato-pancreatico-biliary (HPB) malignancy: accurate staging of disease and resection. We aim to summarize the use of laparoscopy in these contexts. The role of staging laparoscopy has become routine in certain cancers, in particular T2 staged, locally advanced gastric cancer, hilar cholangiocarcinoma and non-Hodgkin's lymphoma. For other cancers, in particular colorectal, laparoscopy has now become the gold standard management for resection such that there is no role for stand-alone staging laparoscopy. In HPB cancers, although staging laparoscopy may play a role, with ever improving radiology, its role remains controversial.
