Abstract：

Laparoscopic cholecystectomy is considered to be the gold standard for the treatment of cholecystolithiasis because of its advantages of less trauma and faster postoperative recovery, but intraoperative stress and postoperative pain still affect patients. Most patients are reluctant to get out of bed early after surgery due to pain, which is not conducive to patients' recovery. At present, ultrasound-guided regional nerve block techniques are gradually mature and applied to laparoscopic cholecystectomy, such as thoracic paravertebral nerve block (TPVB) and erector spinae plane block (ESPB) which have been widely used in clinic in recent years, can be combined with general anesthesia in laparoscopic cholecystectomy to reduce the pain caused by cholecystectomy. Although there are few reports on costotransverse block (CTB),which has been newly proposed in recent years, our team found that it may have greater advantages in cholecystectomy through anatomical observation. This article analyzes the research progress on TPVB, ESPB, and CTB in recent years, and explores the advantages and disadvantages of three different nerve block techniques under ultrasound guidance in laparoscopic cholecystectomy.
