Robotic liver resection can overcome some of the limitations of laparoscopic liver surgery; therefore, it is a promising tool to increase the proportion of minimally invasive liver resections. The present article gives an overview of the current literature. Furthermore, the results of a nationwide survey on robotic liver surgery among hospitals in Germany with a DaVinci system used in general visceral surgery and the perioperative results of two German robotic centers are presented.

There are vast land and lots of people in western China, but the economy developing is relatively slow. However, the minimally invasive surgery was carried out firstly in China. Moreover, the type, number and difficulty of the minimally invasive surgery increased year by year. Especially, in the western area of China, Dr Zhou Zongguang, Yu Peiwu and Zheng Shuguo et al. have performed much pioneering work in laparoscopic surgery for rectal cancer, gastric cancer and laparoscopic liver resection. They led the standard development of minimally invasive in China...

Cholangiocarcinoma (CC) is the second most common type of primary liver cancer after hepatocellular carcinoma. Surgical resection is considered the only curative treatment for CC. In general, laparoscopic liver surgery (LLS) is associated with improved short-term outcomes without compromising the long-term oncological outcome. However, the role of LLS in the treatment of CC is not yet well established. In addition, CC may arise in any tract of the biliary tree, thus requiring different types of treatment, including pancreatectomies and extrahepatic bile duct resections...

Autonomous robotic ultrasound has recently gained considerable interest, especially for collaborative applications. Existing methods for acquisition trajectory planning are solely based on geometrical considerations, such as the pose of the transducer with respect to the patient surface. PURPOSE: This work aims at establishing acoustic window planning to enable autonomous ultrasound acquisitions of anatomies with restricted acoustic windows, such as the liver or the heart. METHODS: We propose a fully automatic approach for the planning of acquisition trajectories, which only requires information about the target region as well as existing tomographic imaging data, such as X-ray computed tomography...

OBJECTIVE: Finding of a significant replaced left hepatic artery (RLHA) during esophagectomy is relatively rare, with an incidence of approximately 5%. Sparing of the artery may be required to avoid complications of liver ischemia. Robotic assistance during esophagectomy may provide a technically superior method of artery preservation with minimally invasive approaches. METHODS: This is a retrospective case series of patients undergoing robotic-assisted minimally invasive esophagectomy (RAMIE) identified to have a significant RLHA at time of surgery...

PURPOSE: Although the metric precision of robotic stereotactic body radiation therapy in the presence of breathing motion is widely known, we investigated the dosimetric implications of breathing phase-related residual tracking errors. METHODS AND MATERIALS: In 24 patients (28 liver metastases) treated with the CyberKnife, we recorded the residual correlation, prediction, and rotational tracking errors from 90 fractions and binned them into 10 breathing phases. The average breathing phase errors were used to shift and rotate the clinical tumor volume (CTV) and planning target volume (PTV) for each phase to calculate a pseudo 4-dimensional error dose distribution for comparison with the original planned dose distribution...

The role of minimally invasive liver surgery as a bridge to transplantation is very promising but still underestimated. However, it should be noted that surgical approach for hepatocellular carcinomas (HCC) is not merely a technical or technological issue. Nowadays, the epidemiology of HCC is evolving due to the increasing role of non-alcoholic fatty-liver-disease, and the emerging concerns on direct-acting antivirals against hepatitis C virus in terms of HCC incidence. Therefore, a fully multidisciplinary study of the cirrhotic patient is currently more important than ever before, and the management of those patients should be reserved to tertiary referral hepatobiliary centers...

BACKGROUND: Laparoscopic liver resection (LLR) has been increasing since it was first reported in 1991. Two international expert consensus conferences on LLR surgery were held in Louisville, KY, USA, in 2008 and in Morioka, Japan, in 2014, respectively. While most initial minimally invasive liver resections were typically done for benign lesions in anterior or left lateral segments, LLR is currently being applied for major anatomic resections, malignancy, cirrhosis, and live donor hepatectomy...

BACKGROUND: One of the perceived major drawbacks of minimally invasive techniques has always been its cost. This is especially true for the robotic approach and is one of the main reasons that has prevented its wider acceptance among hospitals and surgeons. The aim of our study was to evaluate the clinical outcomes and economic impact of robotic and open liver surgery in a single institution. METHODS: Sixty-eight robotic and 55 open hepatectomies were performed at our institution between January 1, 2009 and December 31, 2013...

We introduce a novel optimization-based motion planner, Stochastic Extended LQR (SELQR), which computes a trajectory and associated linear control policy with the objective of minimizing the expected value of a user-defined cost function. SELQR applies to robotic systems that have stochastic non-linear dynamics with motion uncertainty modeled by Gaussian distributions that can be state- and control-dependent. In each iteration, SELQR uses a combination of forward and backward value iteration to estimate the cost-to-come and the cost-to-go for each state along a trajectory...

REVIEW
Atsushi Sugioka, Yutaro Kato, Yoshinao Tanahashi
Anatomical liver resection with the Glissonean pedicle isolation is widely approved as an essential procedure for safety and curability. Especially, the extrahepatic Glissonean pedicle isolation without parenchymal destruction should be an ideal procedure. However, the surgical technique has not been standardized due to a lack of anatomical understanding. Herein, we proposed a novel comprehensive surgical anatomy of the liver based on Laennec's capsule that would give a theoretical background to the extrahepatic Glissonean pedicle isolation...
