  abstract  = {Background The novel coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2), has escalated rapidly to a global pandemic stretching healthcare systems worldwide to their limits. Surgeonshave had to immediately react to this unprecedented clinical challenge by systematically repurposing surgical wards. Purpose To provide a detailed set of guidelines developed in a surgical ward at University Hospital Wuerzburg to safelyaccommodate the exponentially rising cases of SARS-CoV-2 infected patients without compromising the care of emergencysurgery and oncological patients or jeopardizing the well-being of hospital staff. Conclusions The dynamic prioritization of SARS-CoV-2 infected and surgical patient groups is key to preserving life whilemaintaining high surgical standards. Strictly segregating patient groups in emergency rooms, non-intensive care wards andoperating areas prevents viral spread while adequately training and carefully selecting hospital staff allow them to confidentlyand successfully undertake their respective clinical duties.},

  abstract  = {Introduction: During damage control surgery for blunt abdominal traumata simultaneous duodenal perforations can be missed making secondary sufficient surgical treatment challenging. Endoluminal vacuum (EndoVAC™) therapy has been shown to be a revolutionary option but has anatomical and technical limits. Presentation of the case: A 59-year old man with hemorrhagic shock due to rupture of the mesenteric root after blunt abdominal trauma received damage control treatment. Within a scheduled second-look, perforation of the posterior duodenal wall was identified. Due to local and systemic conditions, further surgical treatment was limited. Decision for endoscopic treatment was made but proved to be difficult due to the distal location. Finally, double-barreled jejunal stoma was created for transstomal EndoVAC™ treatment. Complete leakage healing was achieved and jejunostomy reversal followed subsequently. Discussion: During damage control surgery simultaneous bowel injuries can be missed leading to life-threatening complications with limited surgical options. EndoVAC™ treatment is an option for gastrointestinal perforations but has anatomical limitations that can be sufficiently shifted by a transstomal approach for intestinal leakage. Conclusion: In trauma related laparotomy complete mobilization of the duodenum is crucial. As ultima ratio, transstomal EndoVAC™ is a safe and feasible option and can be considered for similar cases.},

  abstract  = {Background Simulator training is an effective way of acquiring laparoscopic skills but there remains a need to optimize teaching methods to accelerate learning. We evaluated the effect of the mental exercise 'deconstruction into key steps' (DIKS) on the time required to acquire laparoscopic skills. Methods A randomized controlled trial with undergraduate medical students was implemented into a structured curricular laparoscopic training course. The intervention group (IG) was trained using the DIKS approach, while the control group (CG) underwent the standard course. Laparoscopic performance of all participants was video-recorded at baseline (t0), after the first session (t1) and after the second session (t2) nine days later. Two double-blinded raters assessed the videos. The Impact of potential covariates on performance (gender, age, prior laparoscopic experience, self-assessed motivation and self-assessed dexterity) was evaluated with a self-report questionnaire. Results Both the IG (n = 58) and the CG (n = 68) improved their performance after each training session (p < 0.001) but with notable differences between sessions. Whereas the CG significantly improved their performance from t0 -t1 (p < 0.05), DIKS shortened practical exercise time by 58\% so that the IG outperformed the CG from t1 -t2, (p < 0.05). High self-assessed motivation and dexterity associated with significantly better performance (p < 0.05). Male participants demonstrated significantly higher overall performance (p < 0.05). Conclusion Mental exercises like DIKS can improve laparoscopic performance and shorten practice times. Given the limited exposure of surgical residents to simulator training, implementation of mental exercises like DIKS is highly recommended. Gender, self-assessed dexterity, and motivation all appreciably influence performance in laparoscopic training.},
