Objective To evaluate the efficacy and safety of holmium laser lithotripsy in the management of cholelithiasis. Methods 17 patients with hepatolithiasis or residual stones after bile duct operation were treated by holmium lithotripsy under fibrocholedochoscope. Results 36 stones were confirmed in 17 patients by intraoperative cholangiography. 7 stones were removed directly, 24 ones by laser lithotripsy, with success rate being 82 8%(24/29). Due to located in superior segmental intrahepatic duct, other 5 stones could not be observed under fibrocholedochoscope, so they weren't treated by holmium laser lithotripsy. B ultrasoundgraphy and cholangiography showed no residual stones in extrahepatic bile duct at the 1st month postoperatively, and the untreated 5 stones were in the same place. No hemorrhage, bile leakage, liver dysfunction or other complications occurred. Conclusions Holmium laser lithotripsy under fibrocholedochoscope is an effective and safe method in the management of hepatolithiasis or residual stones after bile duct operation.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
