Laparoscopic hepatic resection: a new and safe procedure by abdominal wall lifting method.

HCC is well known for its high incidence of intrahepatic tumor recurrence and many patients suffering from them, usually undergo further treatments, such as PEI, TAE, MCNT or hepatic resection. However, conventional hepatic resection by large skin incision causes severe intraabdominal adhesions, which disturb US examination and further treatments. The aim of the laparoscopic procedure is to prevent intraabdominal adhesions. This is a study of the feasibility of laparoscopic hepatic resection without CO2 pneumoperitoneum, which is not yet popular, as a safe and effective procedure. The patient in this study had a solitary HCC in the lateral segment. Mobilization of the lateral segment, dissections of the left hepatic artery and portal venous branches, i.e. P2 and P3, were performed under CO2 gas insufflation. However, to avoid CO2 gas embolism, further procedures, including parenchymal compression and hepatic venous dissection, were performed using the abdominal wall lifting method without pneumoperitoneum. The patient could eat on the second postoperative day and had an uneventful postoperative recovery and was discharged from the hospital 13 days after surgery. Hospital stay was shorter than conventional hepatic resections with large skin incisions. The importance of this procedure lies in that it is not only a minimally invasive procedure, but also provides us with the possibilities of further treatments, including PEI and re-hepatic resection.
