Video-assisted transthoracic liver resection in patients with marginal liver function: a retrospective cohort study

Abstract

Purpose Laparoscopic hepatectomy has been widely performed by hepatobiliary surgeons for malignancy of liver and gained wide acceptance for various liver tumors, thanks to advances in surgical techniques and devices. But, there are some challenges for right side tumor in patients of cirrhotic liver. Especially, tumor located in right upper area is difficult for wedge resection in patients with marginal liver function, because trans-abdominal approach requires normal parenchymal dissection. Radiofrequency wave ablation is also difficult for such a lesion. So, we demonstrate unique technique of video-assisted transthoracic liver resection (VTLR) for overcome right upper side tumor abutting diaphragm. Methods Four patients underwent VTLR. Four ports in right chest wall were created by a chest surgeon and diaphragm was open. Then traction of the diaphragm was done by suture. After exposure of liver surface, tumor localization was done by ultrasound. The mass excision was done by ultrasonic shear. Results Four patients were discharged without complications within 11.3 days (range, 6–15 days). On average, patients started to consume a normal diet on an average of 2.4 days (range, 1–4 days). Conclusion VTLR is could be performed by an experienced surgeon and chest surgeon for right upper liver malignancy abutting diaphragm in patient of marginal liver function.
