EXORA vs ESP Blocks in Laparoscopic Cholecystectomy

Laparoscopic cholecystectomy is still considered the gold standard for the surgical management of gallbladder disease due to its minimally invasive nature, shorter recovery time, and reduced postoperative complications. Despite these advantages, patients frequently experience moderate to severe postoperative pain, particularly in the early postoperative period, which can impede recovery, delay mobilization, and increase opioid consumption. Excessive opioid use after laparoscopic cholecystectomy is associated with several drawbacks, including nausea, vomiting, sedation, and delayed recovery. It also increases the risk of respiratory depression, especially in vulnerable patients, and may contribute to long-term opioid dependence. These risks highlight the importance of opioid-sparing strategies such as regional anesthesia techniques to improve patient outcomes and enhance recovery. Regional anesthesia techniques have emerged as essential components of multimodal analgesia strategies in abdominal surgeries. Among them, the Erector Spinae Plane (ESP) Block has gained popularity due to its relative ease of administration and favorable safety profile. Recently, a novel fascial plane block known as the EXORA block has been introduced as a promising alternative for abdominal wall analgesia. This block, which targets a different anatomical plane, is postulated to provide comparable or superior analgesic efficacy to traditional methods while maintaining safety and simplicity in execution. Given the ongoing pursuit of optimal analgesia with minimal side effects, it is essential to compare emerging techniques, such as the EXORA block, with established methods like the ESP block. The authors hypothesize that the EXORA and the ESP blocks provide superior postoperative analgesia compared to controls in patients undergoing laparoscopic cholecystectomy and that the EXORA block analgesic profile is superior to that of the ESP block.
