Background: Segmental or subsegmental anatomical resection (AR) of hepatocellular carcinoma (HCC) in minimal access liver surgery (MALS) has been technically proposed. The Glissonean approach or dye injection technique are generally adopted. The tumor-feeding portal pedicle compression technique (C-AR) is an established approach in open surgery, but its feasibility in the MALS environment has never been described.
Methods: Eligible patients were prospectively enrolled to undergo laparoscopic or robotic ultrasound-guided C-AR based on HCC location and preoperative identification of a single tumor-feeding portal pedicle. Initial C-AR experience was gained with laparoscopic cases in the beginning of 2020. Following our progressive experience in laparoscopic C-AR, patients requiring AR for HCC were consecutively selected for robotic C-AR.
Results: A total of 10 patients underwent minimal access C-AR. All patients had Child-Pugh A HCC. The surgical procedures included 6 laparoscopic and 4 robotic C-AR. Median tumor size was 3.1 cm (range 2-7 cm). All procedures had R0 margin. Postoperative complications were nil.
Conclusion: C-AR technique is a feasible and promising technique for patients eligible for laparoscopic and robotic AR for HCC. Further data are necessary to validate its applicability to more complex minimal access AR.
