Abstract
For patients with gastrointestinal dysfunction or failure, although parenteral nutrition can maintain nutrition and save their lives, lack of food stimulus during the fasting period can cause abnormal secretion of gastrointestinal fluid, bile, and pancreatic juice, which may result in the abnormal secretion of a series of enzymes and lead to the development of various liver diseases. Recent research has focused on the prevention and treatment of such diseases, and this article reviews the research advances in recent years.
