The case reports and randomized controlled trials published previously mostly used bilateral erector spinae plane block; however, we report a case in which a unilateral erector spinae plane block was performed. Case presentation A 34-year-old male patient who underwent laparoscopic cholecystectomy was scheduled for a unilateral erector spinae plane block. The block was performed preoperatively, followed by the induction of general anesthesia. Conclusions The patient was comfortable and had a visual analog scale score of 2 for 12 h. Thus, we report successful pain management with the unilateral erector spinae plane block; however, more studies are needed for conclusive information.en10.1186/s42077-020-0053-7info:eu-repo/semantics/openAccessErector spinae plane blockUltrasoundLaparoscopic cholecystectomyPostoperative AnalgesiaPainArticle121N/AWOS:000513962900001
