The ultrasound guided erector spinae plane (ESP) block is a recent block described for various surgeries for postoperative analgesia. ESP block has effect on both visceral and somatic pain; therefore, its use in laparoscopic cholecystectomy and other abdominal surgeries can be advantageous. We describe successful ESP block application in three different cases for postoperative pain. Two patient were operated on using endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy and one patient was operated on using laparoscopic cholecystectomy together with the inguinal hernia operation.

Introduction: Erector spinae plane block (ESPB) is a novel regional anesthesia technique used in postoperative pain and chronic neuropathic pain of the thoracoabdominal region. There are no previously published large case series. This retrospective review aimed to report the indications, levels of block, success of block and complications, and also to evaluate the effect of ESPB on postoperative/chronic pain. Methods: We retrospectively evaluated the charts and medical records of 182 patients who had ESPB in the last one year. All records were collected in the postoperative recovery room, ward, and pain unit. Results: ESPB performed at several different levels and for several different indications led to effective postoperative analgesia when part of a multimodal analgesia plan. Few complications were noted. Conclusion: ESPB is an interfascial plane block with many indications. The possibility of complications must be considered.

Background: Oblique subcostal transversus abdominis plane block (OSTAP) is a recently described regional anesthetic technique used in upper abdominal surgeries such as laparoscopic cholecystectomy (LC). Erector spinae plane block (ESPB) has also been reported for postoperative analgesia in LC. Aim: We aimed to compare the effectiveness of OSTAP and ESPB in providing postoperative analgesia in patients undergoing these surgeries. Setting and Design: This study was designed as a double-blinded, prospective, randomized, efficiency study in a tertiary university hospital, postoperative recovery room, and ward. Materials and Methods: A total of 72 patients were recruited and 60 patients were randomized into three equal groups (ESPB, OSTAP, and control group). Pain intensity between groups was compared using Numeric Rating Scale (NRS) scores. In addition, consumption of paracetamol and tramadol and additional rescue analgesic requirement were measured. Standard multimodal analgesia was performed in all groups, while ESPB block was also performed in Group ESPB and OSTAP block was also performed in group OSTAP. Statistical Analysis Used: Descriptive statistics were expressed as mean ± standard deviation. Independent t -test, Mann–Whitney U-test, Chi-square test, Fisher's exact test, Shapiro–Wilk test, one-way ANOVA, and post hoc Tukey's analysis were used for statistical analysis. Results: NRS was lower in block groups during the first 3 h. There was no difference in NRS scores at other hours. Analgesic consumption and rescue analgesic requirement were lower in groups ESPB and OSTAP when compared to those of control group. Block groups were similar. Conclusion: Bilateral ultrasound-guided ESPB and OSTAP performed at the end of LC lead to akin analgesia requirement and improve the quality of multimodal analgesia.
