Totally Laparoscopic Anatomical Hepatectomy Exposing the Major Hepatic Veins from the Root Side: a Case of the Right Anterior Sectorectomy (with Video)

Laparoscopic hepatectomy has rapidly evolved recently; 1‐5 however, laparoscopic anatomical hepatectomy has yet to become widely used, although anatomical hepatectomy is ideal, especially for curative treatment of hepatocellular carcinoma, and is widely accepted via open approach. 6‐10 This is because good-experienced skills, for example, exposing Glissonean pedicles and hepatic veins on the cutting plane, are required in order to perform anatomical hepatectomy via a pure laparoscopic approach. We obtained good results for various totally laparoscopic anatomical hepatectomies using the standardized techniques. We exposed the major hepatic veins from the root side by utilizing the unique view from the caudal side in the laparoscopic approach, and moved CUSA from the root side toward the peripheral side to avoid splitting the bifurcation of the hepatic vein. 11‐13 We performed totally laparoscopic anatomical hepatectomy for 47 patients from August, 2008, to December, 2012 (Table 1). In most types of anatomical hepatectomy, the mean blood loss was <500 ml. Conversion to open surgery was required in two patients. Postoperative complications were prolonged ascites in two, peroneal palsy in two, and biloma in one. Mortality was zero. The embedded video demonstrates totally laparoscopic right anterior sectorectomy. In conclusion, our standardized techniques make laparoscopic anatomical hepatectomy more feasible.
