Abstract:
Hepatobiliary and pancreatic surgery is recognized as technically demanding due to the complicated local anatomy and diverse anatomical variation that require precise techniques. Therefore, preoperative simulation to understand the detailed local anatomy and intraoperative navigation methods for surgical guidance are needed. Intraoperative navigation for anatomical hepatectomy originated with dye injection into the dominant portal pedicle under intraoperative ultrasound guidance to identify hepatic segments, which was reported by Makuuchi et al in 1985. In recent years, with advancing medical technology, newer medical devices that promote the safety and reliability of various surgical procedures have been developed. In this article, we will discuss the current state and future prospects of intraoperative navigation in hepatobiliary and pancreatic surgery.

Pancreatic Juice and Secretion
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...
Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
