Toward structured abdominal examination training using augmented reality.

Purpose: Structured abdominal examination is an essential part of the medical curriculum and surgical training, requiring a blend of theory and practice from trainees. Current training methods, however, often do not provide adequate engagement, fail to address individual learning needs or do not cover rare diseases.

Methods: In this work, an application for structured Abdominal Examination Training using Augmented Reality (AETAR) is presented.

[Virtual reality in liver surgery-Planning, advanced training, testing].

Anatomical structures of the liver could be reconstructed three dimensionally from preoperative cross-sectional imaging for over 20 years. This three-dimensional (3D) representation not only optimizes the preoperative planning options but also the communication of specific operation-relevant structures can be improved using 3D models. In addition to a plastic and interactive visualization of 3D organ models, the disruptive technology of virtual reality (VR) can also provide a possibility for structured training and further education regarding surgical anatomy of the liver and operation planning.

Immersive virtual reality for interdisciplinary trauma management - initial evaluation of a training tool prototype.

Introduction: Emergency care of critically ill patients in the trauma room is an integral part of interdisciplinary work in hospitals. Live threatening injuries require swift diagnosis, prioritization, and treatment; thus, different medical specialties need to work together closely for optimal patient care. Training is essential to facilitate smooth performance.

[Evidence, Availability and Future Visions in Simulation in General and Visceral Surgery].

Practice makes perfect - a saying that everyone has certainly heard. Surgeons of all levels of training can demonstrably practice to some extent on simulators. This training outside the operating theatre and independent of patients makes sense, both ethically and financially.

[Liver Surgery 4.0 - Planning, Volumetry, Navigation and Virtual Reality].

Due to the optimisation of conservative treatment, the improvement of imaging methods and the continuous development of surgical techniques, the borders of resectability in liver surgery have changed significantly in recent decades.Thanks to numerous technical developments, in particular three-dimensional segmentation, preoperative planning and orientation during the operation itself, can now be facilitated, especially in complex procedures.New technologies such as 3D printing as well as virtual and augmented reality offer additional display options for the patients' individual anatomy.

Patient-individualized resection planning in liver surgery using 3D print and virtual reality (i-LiVR)-a study protocol for a prospective randomized controlled trial.

Background: A multitude of different diseases-benign and malign-can require surgery of the liver. The liver is an especially challenging organ for resection planning due to its unique and interindividually variable anatomy. This demands a high amount of mental imagination from the surgeon in order to plan accordingly - a skill, which takes years of training to acquire and which is difficult to teach.

[Surgical Education of Medical Students in Times of COVID-19 - Necessary Adjustments are Chances for the Future].

Background: Education of medical students in surgery not only consists of knowledge about diseases and their treatment but also of practical skills like i.e. suturing.

Transanal total mesorectal excision for restorative coloproctectomy in an obese high-risk patient with colitis-associated carcinoma.

Transanal total mesorectal excision (TaTME) offers great potential for the treatment of malign and benign diseases. However, laparoscopic-assisted TaTME in ulcerative colitis has not been described in more than a handful of patients. We present a 47-year-old highly comorbid female patient with an ulcerative colitis-associated carcinoma of the ascending colon and steroid- refractory pancolitis.

Surgeons' assessment of internal anal sphincter nerve supply during TaTME - inbetween expectations and reality.

Background: Intraoperative identification of nerve fibers heading from the inferior rectal plexus (IRP) to the internal anal sphincter (IAS) is challenging. The transanal total mesorectal excision (TaTME) is said to better preserve pelvic autonomic nerves. The aim of this study was to investigate the nerve identification rates during TaTME by transanal visual and electrophysiological assessment.
