  "abstract": "Background and Aims In the context of postoperative pain management following laparoscopic cholecystectomies, the utilisation of local anaesthetic infiltration into the port sites or the administration of intraperitoneal local anaesthetics is strongly recommended. Erector spinae planus and transversus abdominis plane blocks are recommended as second-line treatment options. The present study investigated the efficacy of the newly discovered External Oblique Intercostal Plan Block (EOIP) block.Methods The study was designed as a prospective randomised controlled, double-blind experiment. In this study, 100 patients undergoing LK surgery were divided into four groups: EOIP Block Group E, OSTAP Block Group O, Local Anesthetic Infiltration Group L and Control Group K. The following outcomes were recorded at 0 h, 30 min, 2 h, 4 h, 12 h and 24 h in the postoperative period: resting and mobile VAS values, amount of total tramadol consumption at pca device, intraoperative remifentanil consumption, 24th hour QoR-15 scores, additional analgesic needs and complications.Results A statistical analysis of the demographic and hemodynamic data revealed no significant differences between the groups. At 12 hours, VAS-I, VAS-H, 24-hour QoR-15 scores and postoperative additional analgesic requirement were statistically significantly lower in Group E compared to all other groups. The requirement for supplementary analgesics was found to be statistically significantly lower in patients who underwent block compared to Groups L and K.Conclusions Çömez et al. found no significant difference between the EOIP block and OSTAP block groups in terms of analgesic effect, postoperative pain scores and opioid use in a study of 70 patients undergoing laparoscopic cholecystectomy. The results of our study demonstrated that EOIP and OSTAP blocks provided more effective analgesia and reduced postoperative opioid consumption compared to trocar site local anesthetic infiltration. Consequently, we advocate the implementation of fascial plane blocks as a primary treatment modality within the framework of multimodal analgesia, contingent upon their execution by seasoned anesthesiologists.",
