Pneumoperitoneum-related complications following laparoscopic cholecystectomy at different pressures: A comparison study / 中国微创外科杂志

ABSTRACT

Objective To study the prevention and treatment of pneumoperitoneum-related complications after laparoscopic cholecystectomy (LC). Methods A retrospective analysis was made on clinical data of 1 100 cases of LC from October 1993 to January 2003. The cases were divided into two groups 980 cases admitted before September 2001 received a 14 mmHg carbon dioxide pneumoperitoneum (Group A), and 120 cases after September 2001 received a 10 mmHg pneumoperitoneum (Group B). Results Carbonemia happened in 2 cases in the Group A but in no cases in the Group B. The incidence of postoperative shoulder pain was significantly lower in the Group B (19 2%, 23/120) than in the Group A (43 9%, 430/980) ( ? 2 =26 951, P =0 000). The incidence of postoperative nausea and vomiting (PONV) was significantly lower in the Group B (25 8%, 31/120) than in the Group A (61 2%, 600/980) ( ? 2 =54 750, P =0 000). Conclusions Carbonemia, shoulder pain and PONV can be reduced by regulating the ventilation and decreasing the pneumoperitoneum pressure.
