Abstract：Fogging is one of major reasons hindering the optimal view in laparoscopic surgery, which not only increases the operation risk and prolongs the operation time, but also increases the operation cost of patients. The leading causes of fogging of laparoscopes include the changes of lens surface temperature and humidity, the use of electrosurgical equipment during operation, and the contamination of lens by substances such as blood and fat.We reviewed the methods and latest research progress of laparoscopic antifogging in clinic for clinical workers' reference.
