Abstract: Objective To explore the application effects and safety of Laparoscopic-guided rectus sheath block on single-incision laparoscopic cholecystectomy. Methods Retrospective analysis was performed on 100 patients who were undergone single-incision laparoscopic cholecystectomy from October 2019 to March 2021, of whom 50 patients were performed laparoscopic-guided rectus sheath block, and others were performed local infiltration anesthasia. Postoperative pain score, first ambulation, complications was compared between two groups. Visual analogue scale was applied to evaluate the pain on 2 h, 6 h、12 h and 24 h after operation. Results There was no significant difference in gender, age, weight, operating time between two groups. The observation group had lower VAS scores at the time of 2 h,and 6 h,12 h after operation as compared with the control group, respectively（1.7±1.1 vs 3.1±1.1, P<0.001; 1.7±1.2 vs 2.7±0.9, P<1.9±0.8 vs 2.4±0.8,P=0.001）. And there was no significant difference at the time of 24 h （1.7±1.0 vs 1.9±1.2, P=0.411）. And the observation group shows superior advantage on the first ambulation（8.3±1.1 vs 10.7±1.5 h, P<0.001）. There were no complications on both groups. Conclusion Laparoscopic-guided rectus sheath block on single-incision laparoscopic cholecystectomy is effective and safe. It is a method to release the pain after operation which is performed by surgeon easily.
