UNASSIGNED: The present randomised clinical trial included 84 patients divided into two groups: standard pressure laparoscopic cholecystectomy (SPLC) (13 mmHg) and LPLC (9 mmHg). The variables tested were abdominal pain at 3, 6, 12 and 24 h (by verbal rating scale), the incidence and intensity of STP, post-operative nausea and vomiting (PONV) and surgeon\'s comfort for the two techniques.
UNASSIGNED: The demographic characteristics of patients were similar in both groups. In LPP group, the postoperative abdominal pain at 6, 12 and 24 h was significantly less than SPLC; p = 0.02. Incidence of shoulder pain was significantly less in low pressure group (7.14%) compared with standard pressure (28.57%).
UNASSIGNED: Low-pressure pneumoperitoneum (LPP) is safe and feasible surgery with reduced abdominal and STP.
■本随机临床试验包括84例患者,分为两组:标准压力腹腔镜胆囊切除术(SPLC)(13mmHg)和LPLC(9mmHg)。测试的变量是3、6、12和24小时的腹痛(通过口头评定量表),STP的发生率和强度,术后恶心和呕吐(PONV)和外科医生对这两种技术的舒适度。
■两组患者的人口统计学特征相似。在LPP组中,术后6、12和24h的腹痛明显少于SPLC;p=0.02。与标准压力(28.57%)相比,低压组的肩痛发生率(7.14%)明显较低。
■低压气腹(LPP)是安全可行的手术,可减少腹部和STP。
