Exact staging of rectal cancer by rigid endoscopy is of utmost importance with respect to tumor location, tumor extension and surface characteristics. In addition, minimally-invasive transanal surgical resection techniques for distal rectal cancer, such as TransAnal Minimally Invasive Surgery (TAMIS), are emerging and represent promising options for total mesorectal excision (TME) with sphincter preserving high-quality functional outcome in complex cases. Prerequisite for manual dexterity and mastership of TAMIS in advanced rectal cancer as well as for TEM (Transanal Endoscopic Microsurgery) in early rectal cancer or large sessile polyps of the rectum is the correct setup of the system and anatomical training with respect to the anus and rectum. In a stepwise manner, diagnostic and therapeutic dissection instruments are introduced as basis to master the handling of instruments and to perform a safe procedure when starting the clinical application in all parts of the rectum and anus.

Dr. Harald F. Busse
Department of Diagnostic and Interventional Radiology, Leipzig University Hospital


Harald Busse is currently heading the Imaging Research Group in the Department of Diagnostic and Interventional Radiology at Leipzig University Hospital. He studied Physics and Medicine at the University of Bonn and received his PhD degree in 1995. Between 1995 and 2000 he held scientific positions in the fields of Biomedical Engineering, Radiology and Information Technology at the University of Southern California (USC), Los Angeles, Düsseldorf University Hospital and Fraunhofer Institute of Applied Information Technology (FIT), Sankt Augustin. His research in Leipzig focuses on the clinical translation of medical enabling technologies, especially for the planning and control of minimally invasive procedures. In 2012, he coedited a book on Interventional MRI.


Most image-guided procedures are carried out with the help of computed tomography (CT) or ultrasound (US) imaging because these modalities are widely available, work relatively fast and are performed in standard rooms. In addition, interventional MRI is generally confronted with long imaging times, strong magnetic fields and limited space in the narrow cylindrical bore. On the other hand, MRI is one of the most powerful diagnostic tools in modern medicine featuring a number of well-known advantages, such as a multitude of inherent tissue contrasts, high sensitivity to relevant functional information like molecular water diffusion or tissue perfusion, or the absence of ionizing radiation. Contraindications to X-ray techniques like CT or whenever findings cannot be properly identified by CT or US imaging, therefore represent clear indications for an MRI-guided approach. Since its inception in the mid-1990s, interventional MRI has experienced a wide array of technical developments, clinical settings and successful applications, practically in any body region, ranging from MRI-guided biopsies to completely MRI-controlled therapies. This session will provide an overview of clinical aspects and indications for MRI-guided interventions and demonstrate the setup, workflow and benefits of a virtual real-time navigation system for standard MRI systems (Figs. 1 and 2).

Learning Objectives

Ablation techniques: radio frequency ablation, microwave ablation, brachytherapy, cryoablation, LITT
Challenges: therapy monitoring (temperature monitoring), safety, MR compatibility


Magnetic resonance imaging (MRI) can be used as imaging modality during minimally invasive interventions such as thermal ablations of soft tissue tumors. Its main advantages therefor are the superior tissue contrast and the possibilities of acquiring images with arbitrary slice positions as well as temperature maps. However, performing such ablation procedures under MRI is still challenging. The MRI environment (strong static magnetic field, switching gradient fields, radio frequency field) places enormous demands on the ablation devices, especially regarding their material compatibility as well as their electromagnetic compatibility. Within the talk, the basic functional principle of several ablation techniques will be discussed regarding their clinical performance (ablation duration, ablation zone, …) and MRI applicability (safety aspects,…).

Medical modeling may be as old as mankind itself. Over the centuries, man has looked at health and disease from different points of view which, during each historical age, have been limited by his overall understanding of reality. Life and death; anatomy and physiology; medicine and surgery have been understood within an evolving frame of reference fueled by an ever-expanding fund of knowledge. Medical models, both primitive and sophisticated, are representations of the human organism, and may be mental, physical, and/or symbolic -- graphical, mathematical, virtual. Throughout history, the various forms of medical models created by man have not necessarily been abandoned as new forms have been introduced, but, in general, have become more refined and have been incorporated into an overall view of health and disease. What is new today is an attempt to formalize medical modeling in line with current scientific and mathematical concepts and research. The resulting Digital Patient Model is capable of incorporating virtually all known facets of the human organism in a form amenable to computer analysis and processing. Our ability to create accurate and predictive medical models is predominantly restricted by limitations in our knowledge-base, and, our ability to create, generate and understand effective symbolic representations. In addition, total medical predictability may also be limited by naturally occurring, random physiological forces; those same forces, even on a molecular level, that ensure adaptability and evolution of living things. Regardless of any limitations, Digital Patient Models provide an effective means of understanding and influencing human health and disease. A properly constructed model can provide a flexible tool for addressing specific medical needs and applications, especially with respect to Personalized, Predictive and Preventive healthcare. Digital Patient Models may directly contribute to the acquisition of medical knowledge when features capable of machine learning are incorporated. This presentation will first provide a brief history of medical modeling with the intention of providing perspective and a frame of reference. Medical modeling will be viewed as a process in evolution and help us understand the many ways we look at the human organism today. Recent efforts to create a Digital Patient Model for hepatocellular carcinoma will then be reviewed. It will be shown how Information Entities derived from many different sub-types of medical models, both old and new, are utilized to construct a comprehensive and modern, Digital Patient Model.

Aims and learning objectives:

  • A perspective for Digital Patient Models, through a review of the development of medical modeling through the ages, will be provided.
  • It will be demonstrated how medical modeling today has evolved into a digital format amenable to computer analysis and processing.
  • Strengths and limitations of Digital Patient Models, especially with respect to predictive and machine learning capabilities will be reviewed.
  • A Digital Patient Model for hepatocellular cancer will be presented and analyzed.
  • The impact of Digital Patient Models on Personalized healthcare and future challenges will be discussed.

Dr. Ronald Schilling


Ronald B. Schilling has experience ranging from research (team that developed CMOS integrated circuits), business development (integrated circuits), marketing (microprocessors), strategic planning (medical imaging), international (1st CT in China), general management (CT, MRI, neurovascular), CEO (interactive virtual reality), investment banking and venture capital. In all of the above, the common theme has been “thinking outside the box.” Essentially, using the elements to create a better way of achieving an opportunity. For example, using interactive virtual reality (IVR) as an approach for “Bridging the Radiology-Surgery Gap.” This is done by recognizing that IVR creates a Visualization Driven Communication Vehicle between Radiology and Surgery. Experience in the above areas has led to a course at Stanford, “Tools for Strategic Management.” The idea is to select the “right tool for the right job.” This approach allows teams to create the best solution since their ability to communicate strategically is significantly increased.

Aims and learning objectives

“Bridging the Radiology-Surgery Gap,” is an example of using Interactive Virtual Reality (IVR) as an approach to creating a Visual Communication tool. Radiologist has stated that with IVR she can speak more intelligently with Surgeons. A Surgeon has stated that when opening up patients, one never sees a 2D view. Thinking strategically about these points leads one to think about creating the bridge. This course will discuss the concepts bringing the above elements together.

  • Participants will be provided with examples of bio-inspired tools and miniature tools for surgery and therapy.

A bio-inspired manipulator for minimally invasive surgery
A soft-tether capsule for targeted therapy and diagnosis


Robotic manipulators have been introduced for the first time in surgery in 1985, when a Puma 560 was used by Kwoh et al. for performing neurosurgical biopsies with high precision. After that milestone, robots and robotic technologies have gained an increasingly important role in surgery, thanks to the accuracy and repeatability they could add to surgical tasks. The introduction of robots in surgical rooms have also entailed important issues in terms of cost, safety, reliability, which are lively debated even today. From the original task of increasing accuracy and repeatability, robots today are asked to do more: they should be un-intrusive and safe, they should perform better some tasks and they should reach areas normally not reachable by traditional surgical solutions. The quest for minimally invasiveness led to medical robots with a more friendly design, where bio-inspiration plays a major role. The quest for miniaturization and natural access led to the development of diagnostic and surgical tools to be delivered with an endoluminal and transluminal approach, and to be controlled by innovative remote operation schemes from outside. The quest for targeted therapy has recently opened new opportunities for robots, which are used more and more as controllers for the delivery of drugs collected by nanobiotech vectors. This talk aims to present the above mentioned trends, with the support of specific examples coming from the speaker experience and her collaboration network.

Surgery today is located in a very competitive environment. Accordingly, this discipline is forced to become increasingly more innovative in order to be able to offer attractive therapeutic options to the patients. Less invasive therapeutic alternatives are continuously developed by interventional endoscopy and interventional radiology. Some parts of the surgical domain will be even lost to medical treatment. If surgery is willing to survive, it has to optimize the outcome and, simultaneously, to reduce the surgical trauma and the expenses. These contradicting aims can only be reached by the combined use of cyber-physical systems. Digitalisation of surgery may be denominated as “surgery 4.0”. This process will be primarily focussed on the surgical operation room which is the “profit centre” of any surgical unit. The aim is to transform it into a “collaborative environment”. Based upon a multitude of continuous real time data, a support system should be capable to interpret the actual situation (context sensitivity) and to predict the next steps required. In addition to the necessary medical and organizational structured knowledge which has to be provided before, the system should be able to learn from repeated procedures. Thus, it should offer active assistance to the surgical team to use the technical environment adequately, to smoothen the workflow, to avoid mistakes and to improve the safety level. To reach this goal, some preconditions have still to be met: Comprehensive systems integration, the development of surgical and patient models and a perfect communication not only between the devices and instruments but also with the human user. Making this vision mature for regular clinical care is challenging but first promising approaches have already been developed.

Aims and learning objectives:

  • showing development of the digitalization of surgery (surgery 4.0)
  • showing development of surgical and patient models and communication between devices and human user

Leipzig is always worth a visit. The city of Linden, is now over a thousand years old and Germany's fastest growing city. Famous events in European history such as the Battle of Leipzig in 1813 and the Peaceful Revolution in 1989 are associated with it. Today, Leipzig is a key center of commerce, culture and learning. Moreover, the city has become an attractive business location in Central Germany. It focuses on expanding industries such as biotech and biomedical engineering. The result is an extended landscape of higher education and the establishment of important research centers. After work a guided tour through Leipzig city center or a pub visit are planned to better get to know the location and your international colleagues.
