Laparoscopic liver resection have developed and is widely spread as standard procedure in these days, however, laparoscopic anatomic liver resection is still challenging, especially for posterosuperior lesions because of difficulties in segmental mapping and surgical techniques. Recently, the positive staining and negative staining method using fluorescent imaging techniques have been reported from experienced Asian centers, allowing to identify the tumor-bearing portal territory to be resected including the posterosuperior segment in laparoscopy. Those techniques are applicable in some cases; hence, it remains the room for improvement to establish as a feasible approach. Herein, we describe a percutaneous tumor-bearing portal vein puncture method under artificial ascites after the pneumoperitoneum for laparoscopic segmentectomy for segment 8.
