Background:
Laparoscopic liver resection has become popular recent years. Laparoscopic left lateral sectionectomy (LLS) is now a standard operation with sufficient safety and feasibility. To improve the benefits of minimally invasive surgery, we invented and have been performing a reduced port LLS procedure using 3 ports since 2009.
Materials And Methods:
All patients who underwent LLS at Toranomon Hospital (Tokyo, Japan) were included, except for patients with a previous history of upper abdominal surgery or those who had undergone the simultaneous resection of another organ. An essential point of this procedure was the extracorporeal traction of the divided round ligament using a ligature. As a result, the operator was able to perform the parenchymal transection within a good operative field.
Results:
Twelve patients were enrolled in the study. All the patients had a Child-Pugh classification of Class A. The median indocyanine green retention rate at 15 min was 9.5%. Compared with previously reported results for conventional LLS, the median operation time (82.5 min), blood loss (0 mL) and rate of blood transfusion (0%) were lower for the 3-port LLS procedure. The rates of complications (9%) and a positive surgical margin (0%) were similar to those reported for the conventional approach.
Conclusion:
Three-port LLS appears to be a safe and feasible procedure.
