BackgroundThe feasibility and safety of low-pressure pneumoperitoneum in laparoscopic cholecystectomy remain unclear.MethodsA meta-analysis of randomized controlled trials comparing low-pressure with standard-pressure pneumoperitoneum was performed.ResultsA total of 1,263 patients were included. Low-pressure pneumoperitoneum was associated with significantly decreased postoperative pain. The requirement for increased pressure was significantly greater in the low-pressure group (risk ratio = 6.16; P < .001). Operative time was similar, with only a slight statistical significance (weighted mean difference = 2.07; P < .001). Length of hospital stay was shorter in the low-pressure group (weighted mean difference = −.27; P = .01). No significant differences were found in surgical complications or conversion to open surgery.ConclusionsLow-pressure pneumoperitoneum is feasible and safe and results in reduced postoperative pain and near-equal operative time compared with standard-pressure pneumoperitoneum. More studies are required to investigate the potential benefits of the reduced length of hospital stay.
