  •   Objective  To investigate the value of optical trocar insertion technique in establishing pneumoperitoneum in patients undergoing laparoscopic surgery after previous abdominal surgery.  Methods  A total of 29 patients, with a history of abdominal surgery, who planned to undergo laparoscopic liver surgery were enrolled and randomly divided into optical trocar insertion group and open approach group. The independent samples t-test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the Fisher's exact test was used for comparison of categorical data between groups; the Mann-Whitney U test was used for comparison of ranked data between groups.  Results  There were no procedure-related complications in either group. Compared with the open approach group, the optical trocar insertion group had a significantly shorter time required to establish pneumoperitoneum [35.00 (21.00-46.00) seconds vs 180.00 (152.50-252.50) seconds, U=0, P < 0.001] and a significantly smaller incision length [1.10(1.00-1.20) cm vs 2.80(2.45-3.00) cm, U=0, P < 0.001].  Conclusion  Both optical trocar insertion and open approach for establishing pneumoperitoneum is relatively safe in patients undergoing laparoscopic liver surgery after previous abdominal surgery, while optical trocar insertion has the advantages of high efficiency and minimal invasiveness in establishing pneumoperitoneum.
