<div><p><i>Background</i>. Laparoscopic cholecystectomy (LC) often results in postoperative pain, especially in the abdomen. Intraperitoneal local anesthesia (IPLA) reduces pain after LC. Acute cholecystitis–associated inflammation, increased gallbladder wall thickness, dissection difficulties, and a longer operative time are several reasons for assuming a benefit in pain scores in urgent LC with IPLA application. The aim was to determine the postoperative analgesic efficacy of high-volume, low-dose intraperitoneal bupivacaine in urgent LC. <i>Materials and Methods</i>. Fifty-seven patients who were American Society of Anesthesiologists physical status I or II were randomly assigned to receive either normal saline (control group) or intraperitoneal bupivacaine (test group) at the beginning or end of urgent LC. The primary outcome was the postoperative pain score of the Visual Analogue Scale (VAS). The secondary outcomes included Visual Rating Prince Henry Scale (VRS), patient satisfaction, and analgesic consumption. <i>Results</i>. Postoperative VAS scores at the first and fourth hours were significantly lower in the test group than in the control group (<i>P</i> < .001). Postoperative VRS scores at the first, fourth, and eighth hours were significantly lower in the test group than in the control group (<i>P</i> < .001, <i>P</i> = .002, <i>P</i> = .004, respectively). Analgesic use was significantly higher in the control group at the first postoperative hour (<i>P</i> < .001). Shoulder pain was significantly lower, and patient satisfaction was significantly higher in the test group relative to the control group (both <i>P</i> < .001). <i>Conclusion</i>. High-volume, low-concentration intraperitoneal bupivacaine resulted in better postoperative pain control and reduced incidence of shoulder pain and analgesic consumption in urgent LC.</p></div>
