Application of argon beam coagulator in high abdominal pressure management during laparoscopic hepatectomy

Objective: To study the application of argon beam coagulator（ABC） in high abdominal pressure management during laparoscopic hepatectomy（LH）. Methods: A retrospective analysis of the clinical data obtained from 7 patients undergoing LH in August 2008-December 2008.ABC was used in all the patients during LH.The trocar air release valve was closed two minutes after ABC was used,and the abdominal pressure was measured. Results: The abdominal pressure was（11.571±0.787） mmHg（1mmHg = 0.133kPa） and（12.143±0.900） mmHg,respectively,in the two groups before and after ABC was used（P＜0.05）. Conclusion: ABC can reduce the high abdominal pressure during LH.when the trocar air release valve is opened.
