Dr. Tagaya is an Associate Professor of Surgery in Dokkyo Medical University Koshigaya Hospital. He is presently working as a leading laparoscopic and endoscopic surgeon, and has been accumulating an extremely vast experience with hepatobiliary and gastrointestinal operations, as well as adrenal and bariatric surgery. He also studied liver transplantation at Queensland Liver Transplant Service in Brisbane, Australia from April 1994 to March 1996. This technique is useful for performing laparoscopic liver resection and vascular reconstruction. He is a recipient of a Video Award by the European Association for Endoscopic Surgery in 2007 with regards to double-balloon endoscopy. He is now investigating the technique of fluorescence imaging using indocyanine green during laparoscopic procedures and image overlay surgery as a navigation surgery.

Liver biopsy is a procedure that involves obtaining a small piece of liver tissue, which is then analyzed in the laboratory. Liver biopsy may be used to evaluate a mass seen on images, diagnose unexplained liver diseases or abnormal liver function tests, and to determine the severity of the liver disease including hepatitis, fibrosis, and steatosis. Liver biopsy is an invasive procedure, and its complications are rare but potentially lethal. Therefore, it is necessary to perform liver biopsy safely from clinical aspect and to take specimen steadily from a pathological one. I hope this book addresses the future aspects of liver biopsy including role, indication, technique and evaluation. Furthermore, this book introduces new non-invasive alternatives including elastography and computer analysis of liver fibrosis.
