STUDY OBJECTIVE: To compare the use of low pneumoperitoneum pressure (LPP; 8 mm Hg) vs standard pneumoperitoneum pressure (SPP; 12 mm Hg) during mini-laparoscopic hysterectomy (MLH). DESIGN: Randomized controlled trial (Canadian Task Force classification I). SETTING: Tertiary care center. PATIENTS: Forty-two consecutive women scheduled to undergo MLH to treat benign uterine disease. INTERVENTIONS: Women were randomly selected to undergo MLH using LPP (n = 20) or SPP (n = 22). MLH was performed via 3-mm ancillary ports. MEASUREMENTS AND MAIN RESULTS: The primary outcome was to evaluate changes in abdominal and shoulder-tip pain via a 100-mm visual analog scale at 1, 3, and 24 hours postoperatively. All procedures were completed via mini-laparoscopy without the need to increase intra-abdominal pressure or convert to conventional laparoscopy or open surgery. Intraoperatively, 1 episode of severe bradycardia occurred in the LPP group, whereas no intraoperative complications were recorded in the SPP group (p = .47). No postoperative complications were recorded (p > .99). Abdominal pain was similar between groups at each time point. Incidence and intensity of shoulder-tip pain at 1 and 3 hours postoperatively was lower in the LPP group than in the SPP group (p < .05), whereas no between-group differences were observed at 24 hours (p > .05). Rescue analgesic requirement did not differ statistically between the LPP and SPP groups (20% vs 41%, respectively; p = .19; odds ratio, 2.7; 95% confidence interval, 0.69-11.08). CONCLUSION: In experienced hands, use of LPP is safe and feasible. During performance of MLH, compared with SPP, LPP is a simple method that offers advantages of less shoulder-tip pain.
