Effects of training in pairs versus training alone on reaching proficiency in minimally invasive Roux-en-Y-gastric bypass on a virtual reality trainer in medical students: a randomized-controlled trial.

Background: Minimally invasive surgery (MIS) is the standard approach in bariatric surgery. The most common bariatric procedures are sleeve gastrectomy and Roux-en-Y-Gastric Bypass (RYGB). Simulation training, including virtual reality (VR), is useful when learning MIS.

Artificial intelligence for intraoperative video analysis in robotic-assisted esophagectomy.

Background: Robotic-assisted minimally invasive esophagectomy (RAMIE) is a complex surgical procedure for treating esophageal cancer. Artificial intelligence (AI) is an uprising technology with increasing applications in the surgical field. This scoping review aimed to assess the current AI applications in RAMIE, with a focus on intraoperative video analysis.

Cognitive learning versus practical "hands-on" training for acquisition of laparoscopic surgical skills: an optimal combination study.

Background: Most minimally invasive surgery (MIS) training curricula involve practical training (PT) and cognitive learning (CL) to different extents. It has been proven that acquiring and training specific skills through CL can improve MIS skills. This study aimed to discover the most efficient combination of these two approaches and examine their effects on acquiring MIS skills in novices.

Intraoperative liver deformation and organ motion caused by ventilation, laparotomy, and pneumoperitoneum in a porcine model for image-guided liver surgery.

Background: Image-guidance promises to make complex situations in liver interventions safer. Clinical success is limited by intraoperative organ motion due to ventilation and surgical manipulation. The aim was to assess influence of different ventilatory and operative states on liver motion in an experimental model.

[Splenic surgery in hematological diseases : Indications and surgical technique].

Background: Splenic surgery in hematological disorders requires a well-weighted decision on the indications because the medical treatment has rapidly changed in recent years due to new pharmaceutical approaches.

Objective: Summary of the indications, surgical procedures and perioperative management regarding operative interventions on the spleen in hematological disorders.

Material And Methods: Selective literature search and summary of reviews and guideline recommendations.

IMHOTEP: cross-professional evaluation of a three-dimensional virtual reality system for interactive surgical operation planning, tumor board discussion and immersive training for complex liver surgery in a head-mounted display.

Background: Virtual reality (VR) with head-mounted displays (HMD) may improve medical training and patient care by improving display and integration of different types of information. The aim of this study was to evaluate among different healthcare professions the potential of an interactive and immersive VR environment for liver surgery that integrates all relevant patient data from different sources needed for planning and training of procedures.

Methods: 3D-models of the liver, other abdominal organs, vessels, and tumors of a sample patient with multiple hepatic masses were created.

Effects of laparoscopy, laparotomy, and respiratory phase on liver volume in a live porcine model for liver resection.

Background: Hepatectomy, living donor liver transplantations and other major hepatic interventions rely on precise calculation of the total, remnant and graft liver volume. However, liver volume might differ between the pre- and intraoperative situation. To model liver volume changes and develop and validate such pre- and intraoperative assistance systems, exact information about the influence of lung ventilation and intraoperative surgical state on liver volume is essential.

One or two trainees per workplace for laparoscopic surgery training courses: results from a randomized controlled trial.

Background: There are no standards for optimal utilization of workplaces in laparoscopic training. This study aimed to define whether laparoscopy training should be done alone or in pairs (known as dyad training).

Methods: This was a three-arm randomized controlled trial with laparoscopically naïve medical students (n = 100).

Mobile, real-time, and point-of-care augmented reality is robust, accurate, and feasible: a prospective pilot study.

Background: Augmented reality (AR) systems are currently being explored by a broad spectrum of industries, mainly for improving point-of-care access to data and images. Especially in surgery and especially for timely decisions in emergency cases, a fast and comprehensive access to images at the patient bedside is mandatory. Currently, imaging data are accessed at a distance from the patient both in time and space, i.

Study protocol for a randomized controlled trial on a multimodal training curriculum for laparoscopic cholecystectomy - LapTrain.

Background: Although minimally invasive surgery (MIS) has replaced many open procedures in visceral surgery, technical and psychomotor obstacles remain a constant challenge for surgeons and trainees. However, there are various training curricula enabling surgeons to acquire the visuospatial and psychomotor abilities additionally required when performing MIS. Currently accepted training modalities include box-trainers, organ and animal models as well as completely simulated training environments, realized in virtual reality (VR) trainers.

Paradigm shift: cognitive surgery.

In the last hundred years surgery has experienced a dramatic increase of scientific knowledge and innovation. The need to consider best available evidence and to apply technical innovations, such as minimally invasive approaches, challenges the surgeon both intellectually and manually. In order to overcome this challenge, computer scientists and surgeons within the interdisciplinary field of "cognitive surgery" explore and innovate new ways of data processing and management.

Direct Observation versus Endoscopic Video Recording-Based Rating with the Objective Structured Assessment of Technical Skills for Training of Laparoscopic Cholecystectomy.

Purpose: The validated Objective Structured Assessment of Technical Skills (OSATS) score is used for evaluating laparoscopic surgical performance. It consists of two subscores, a Global Rating Scale (GRS) and a Specific Technical Skills (STS) scale. The OSATS has accepted construct validity for direct observation ratings by experts to discriminate between trainees' levels of experience.
