Purpose: A robotic platform has enabled extremely low-pressure pneumoperitoneum (ELPP, 4 mmHg) to reduce surgical insults to human physiology during a minimally invasive surgery. The objective of this study was to investigate the effect of ELPP in single-site robotic cholecystectomy (SSRC) on postoperative pain, shoulder pain, and physiological changes during surgery compared to a standard pressure pneumoperitoneum (SPP, 12–14 mmHg). Methods: A total of 182 patients who underwent an elective cholecystectomy were randomized into an ELPP SSRC group (n = 91) and an SPP SSRC group (n = 91). Postoperative pain was assessed at 6, 12, 24, and 48 h after surgery. The number of patients complaining of shoulder pain was observed. Intraoperative changes of ventilatory parameters were also measured. Results: Postoperative pain scores (p = 0.038, p < 0.001, p < 0.001, and p = 0.015 at 6, 12, 24, and 48 h after surgery, respectively) and the number of patients with shoulder pain (p <0.001) were significantly lower in the ELPP SSRC group than in the SPP SSRC group. Intraoperative changes in peak inspiratory pressure (p < 0.001), plateau pressure (p < 0.001), EtCO2 (p < 0.001), and lung compliance (p < 0.001) were also less in the ELPP SSRC group. Conclusion: The ELPP during robotic cholecystectomy could significantly relieve postoperative pain and shoulder pain. In addition, the ELPP can reduce changes in lung compliance during surgery and the demand for postoperative analgesics, thereby improving the quality of life of patients during early stages of postoperative rehabilitation.
