Laparoscopic liver resection has been applied to treat most indications for liver resection during the past two decades. According to the literature, patient numbers have increased exponentially as a result, and surgical difficulty has increased as well. In expert centers, laparoscopic anatomical hemihepatectomy and major liver resection more than 3 segments have become the acceptable treatment. Moreover, with surgical innovations and accumulated experience, living donor liver transplantation has become an established treatment choice for patients on the transplant waiting list...

PURPOSE: The Synchrony™ Respiratory Tracking System of the CyberKnife® Robotic Radiosurgery System (Accuray, Inc., Sunnyvale CA) enables real-time tracking of moving targets such as lung and liver tumors during radiotherapy. Although film measurements have been used for quality assurance of the tracking system, they cannot evaluate the temporal tracking accuracy. We have developed a verification system using a plastic scintillator that can evaluate the temporal accuracy of the CyberKnife Synchrony...

Background: The premise of minimally invasive surgery (MIS) is to minimize facial and muscle injury in order to enhance recovery from surgery. Robotic MIS surgery for resection of tumors in solid organs is gaining traction, though clear superiority of this approach is lacking and robotic surgery is more expensive. Our philosophy in robotically-assisted hepatectomy has been to employ this approach for cases where location of tumors make difficult a classical laparoscopic approach (superior/posterior tumors), and cases where the incision for an open operation dominates the course of recovery...

Esophageal surgery has been recognized as very challenging for surgeons and risky for patients. Thoracoscopic approach have proved its benefit in esophageal surgery but has some drawbacks as tremor and limited degrees of freedom, contra-intuitive movements and fulcrum effect of the surgical tools. Robotic technology has been developed with the intent to overcome these limitations of the standard laparoscopy or thoracoscopy. These benefits of robotic procedure are most advantageous when operating in remote areas difficult to reach as in esophageal surgery...

Currently, cows with poor metabolic adaptation during early lactation, or poor metabolic adaptation syndrome (PMAS), are often identified based on detection of hyperketonemia. Unfortunately, elevated blood ketones do not manifest consistently with indications of PMAS. Expected indicators of PMAS include elevated liver enzymes and bilirubin, decreased rumen fill, reduced rumen contractions, and a decrease in milk production. Cows with PMAS typically are higher producing, older cows that are earlier in lactation and have greater body condition score at the start of lactation...

Timing of resection and treatment of colorectal cancer (CRC) with liver metastases varies based on patient characteristics and center protocols. Concerns of increased morbidity and mortality (M&M) related to anesthetic time and blood loss have limited widespread adaptation of synchronous colorectal and liver resections. Furthermore, technical challenges have made minimally invasive synchronous resections less common. We present our series of synchronous robotic surgery for CRC with liver metastases. Retrospective review of prospectively collected data of patients with stage IV CRC with liver metastases treated at a tertiary center from February 2013 to June 2014...

Background: Laparoscopic liver resection has been gaining momentum, and it has become an accepted practice after the two international consensus conferences where experts worked up guidelines to standardize this approach and improve its safety. However, most laparoscopic hepatectomies were performed in patients with liver metastases. The concurrent presence of liver cirrhosis with hepatocellular carcinoma (HCC) poses a great challenge to clinicians trying to establish a routine use of laparoscopic liver resection for HCC...

Purpose: The treatment of liver metastases with local procedures is a fast progressing field. For the most, long-term survival data is missing raising questions with regard to the efficacy of such modalities when compared to surgical resection. Radiosurgery using the CyberKnife device enables the treatment of liver lesions with a single-session approach. Here we present long-term survival data to explore the curative potential of this strategy. Materials and Methods: Patients with oligo-metastatic disease limited to the liver have been treated with single-session or hypo-fractioned radiosurgery in curative intent and prospectively followed until death...

REVIEW
Philipp Stiegler, Peter Schemmer
Minimally invasive surgery is standard procedure for many operations. Further refinements include the introduction of robotic surgery which is still an emerging field especially in laparoscopic surgery. Since the successful introduction of the da Vinci Robotic Surgical System, the robotic approach in organ transplantation has become of great interest in both the live donor organ retrieval and the recipient operation. Robotic surgery for kidney, liver, and pancreas transplantation is feasible. Over 700 donor nephrectomies and 100 kidney transplantations have been performed already, and robotic surgery is standard in a small number of pioneer centers; however, larger series and most importantly randomized controlled trials for the highest evidence are needed...

Forensic postmortem case interpretation can be challenging, in particular due to postmortem redistribution (PMR) phenomena. Recent studies have shown that computed tomography (CT)-guided collection of biopsy samples using a robotic arm (virtobot) provides a valuable tool for systematic studies on time-dependent PMR. Utilizing this strategy, several cases involving opioid use such as methadone, fentanyl, tramadol, codeine, oxycodone and hydrocodone were evaluated for time-dependent concentration changes and potential redistribution mechanisms...
