Abstract
Background
To evaluate the safety and efficacy of IOUS in robotic liver surgery and propose a standard protocol of IOUS for safe robot-assisted hepatectomy.
Methods
Between February 2015 and December 2016, liver resection was performed in 110 patients with robotic approach in Tongji Hospital. In these patients, IOUS was routinely performed. All data about demographic, surgical procedure, postoperative course were collected prospectively and analyzed.
Results
A four steps IOUS protocol in robotic liver surgery was proposed, including exploration, verification, guidance, and confirmation. A total of 11 additional lesions in 11 patients were detected and 7 patients accepted strategic surgical modification. No patient suffered from any single or multiple organ dysfunctions, and there were no mortalities observed.
Conclusion
IOUS is indispensable to understand lesions and vessels in robotic liver surgery. A four-step standard protocol of IOUS is essential for safe robot-assisted hepatectomy.
