Abstract
An elevated percentage of medical personnel reports using alcohol to relieve stress. Levels of alcohol addiction are almost double that of the general population. Robotic surgery is becoming more widespread. The purpose of this study is to evaluate the effects of alcohol ingestion on performance of a standardized curriculum using a robotic training platform. Surgeons and surgical trainees were recruited. Candidates performed 4 standardized exercises (Vitruvian Operation (VO), Stacking Challenge (SC), Ring Tower (RT), Suture Sponge (SS)) at 0.0 blood alcohol concentration (BAC), followed by testing in the elimination phase at a target BAC of 0.8‰. Learning effects were minimised through prior training. A total of 20 participants were recruited. Scores for RT and SS exercises were significantly worse under the influence of alcohol [instruments out of view (SS (z = 2.012; p = 0.044), RT (z score 1.940, p = 0.049)), drops (SS (z = 3.250; p = 0.001)), instrument collisions (SS (z = 2.460; p = 0.014)), missed targets (SS (z = 2.907; p = 0.004)]. None of the scores improved with alcohol consumption, and there were measurable deleterious effects on the compound indicators risk affinity and tissue handling. Despite the potential mitigating features of robotic surgery including tremor filtration, motion scaling, and improved three-dimensional visualization, alcohol consumption was associated with a significant increase in risk affinity and rough tissue handling, along with a deterioration of performance in select virtual robotic tasks. In the interest of patient safety, alcohol should not be consumed prior to performing robotic surgery and sufficiently long intervals between alcohol ingestion and surgical performance are mandatory.

Abstract
Recent developments in data science in general and machine learning in particular have transformed the way experts envision the future of surgery. Surgical Data Science (SDS) is a new research field that aims to improve the quality of interventional healthcare through the capture, organization, analysis and modeling of data. While an increasing number of data-driven approaches and clinical applications have been studied in the fields of radiological and clinical data science, translational success stories are still lacking in surgery. In this publication, we shed light on the underlying reasons and provide a roadmap for future advances in the field. Based on an international workshop involving leading researchers in the field of SDS, we review current practice, key achievements and initiatives as well as available standards and tools for a number of topics relevant to the field, namely (1) infrastructure for data acquisition, storage and access in the presence of regulatory constraints, (2) data annotation and sharing and (3) data analytics. We further complement this technical perspective with (4) a review of currently available SDS products and the translational progress from academia and (5) a roadmap for faster clinical translation and exploitation of the full potential of SDS, based on an international multi-round Delphi process.

Abstract
Background For over a decade, the preoperative timeout procedure has been implemented in most paediatric surgery units. However, the impact of this intervention has not been systematically studied. This study evaluates whether purposefully introduced errors during the timeout routine are detected and reported by the operating team members. Methods After ethics board approval and informed consent, deliberate errors were randomly and clandestinely introduced into the timeout routine for elective surgical procedures by a paediatric surgery attending. Errors were randomly selected among wrong name, site, side, allergy, intervention, birthdate and gender items. The main outcome measure was how frequent an error was reported by the team and by whom. Results Over the course of 16 months, 1800 operations and timeouts were performed. Errors were randomly introduced in 120 cases (6.7%). Overall, 54% of the errors were reported; the remainder went unnoticed. Errors were pointed out most frequently by anaesthesiologists (64%), followed by nursing staff (28%), residents-in-training (6%) and medical students (1%). Conclusion Errors in the timeout routine go unnoticed by the team in almost half of cases. Therefore, even if preoperative timeout routines are strictly implemented, mistakes may be overlooked. Hence, the timeout procedure in its current form appears unreliable. Future developments may be useful to improve the quality of the surgical timeout and should be studied in detail.

Abstract
Ziel der Studie
Die geltenden verschärften Hygieneempfehlungen
des Robert-Koch-Instituts zur Eindämmung der Ausbreitung des Coronavirus
mit Versammlungsverbot und Mindestabstand sind im innerklinischen Alltag nicht
umsetzbar. Zur Minimierung von persönlichen Kontakten wurden die
internen Arztkonferenzen auf ein Videokonferenzformat
umgestellt.
Methodik
Innerhalb 24 Stunden wurde unter Anschaffung von
Standard-Webcams, Auswahl eines lizenzierten Videoanbieters und Ausnutzen der
bereits vorhandenen technischen Geräte die allgemeine Hygienerichtlinie
für unsere Mitarbeiter umgesetzt. Häufige Fehlerquellen im
Rahmen der Videokonferenz wurden protokolliert und technische Lösungen
erarbeitet.
Ergebnisse
Die Videokonferenz ermöglichte die
adäquate Patientenversorgung und Aufrechterhaltung der gewohnten
organisatorischen Abläufe. In 4 Wochen konnten 956 persönliche
Kontakte vermieden werden. Die meisten Fehler traten im Rahmen der ersten
Teilnahme einer Person oder Erstanmeldung eines Gerätes auf. Die
häufigsten Fehler betrafen die Tonqualität und konnten umgangen
werden, indem nur an der Diskussion beteiligte Teilnehmer ihr Mikrofon
für die Sprechdauer
aktivierten.
Schlussfolgerung
Mitarbeiterkonferenzen im Videoformat
können mit geringem personellem und technischem Aufwand etabliert
werden, um der Ausbreitung des Coronavirus unter medizinischem Personal
entgegenzuwirken.

Abstract
BACKGROUND There is limited time within the clinical workflow of most pediatric surgeons to obtain a comprehensive, well informed consent. This study evaluates whether ad-lib access to an online video on the consent dialogue enhances the consent process for inguinal hernia repair (IHR) in children. METHODS The study was approved by the state ethics board. A 6-min video of a consent speech on IHR was produced and uploaded to a nonpublic online channel, explaining the condition, procedure, complications, and postoperative expectations. A total of 50 families were randomized to conventional, face-to-face consenting in clinic either with (intervention) or without (control) access to the online video. During their child's IHR, the parents were asked to complete the State-Trait-Anxiety Inventory (STAI), a modified Friedlander questionnaire on assessing knowledge sufficient to provide informed consent, and a validated satisfaction survey. Scores of the intervention and control group were statistically compared. RESULTS The intervention group demonstrated significantly decreased anxiety measured with the STAI (p = 0,026) and increased knowledge (p = 0,016) compared to controls. There was no difference in satisfaction (p = 0,557). CONCLUSION Preoperatively providing access to an online consent video regarding IHR reduces anxiety and enhances knowledge without altering satisfaction level. Adjunct online videos are a useful tool to enhance the consent process. TYPE OF STUDY Prospective randomized controlled trial. LEVEL OF EVIDENCE Level I.

Abstract
BACKGROUND Multiphoton microscopy (MPM) facilitates three-dimensional, high-resolution functional imaging of unlabeled tissues in vivo and ex vivo. This systematic review discusses the diagnostic value, advantages and challenges in the practical use of MPM in surgical oncology. METHOD AND FINDINGS A Medline search was conducted in April 2019. Fifty-three original research papers investigating MPM compared to standard histology in human patients with solid tumors were identified. A qualitative synopsis and meta-analysis of 14 blinded studies was performed. Risk of bias and applicability were evaluated. MPM can image fresh, frozen or fixed tissues up to a depth 1000 μm in the z-plane. Best results including functional imaging and virtual histochemistry are obtained by in vivo imaging or scanning fresh tissue immediately after excision. Two-photon excited fluorescence by natural fluorophores of the cytoplasm and second harmonic generation signals by fluorophores of the extracellular matrix can be scanned simultaneously, providing high resolution optical histochemistry comparable to standard histology. Functional parameters like fluorescence lifetime imaging or optical redox ratio provide additional objective information. A major concern is inability to visualize the nucleus. However, in a subpopulation analysis of 440 specimens, MPM yielded a sensitivity of 94%, specificity of 96% and accuracy of 95% for the detection of malignant tissue. CONCLUSION MPM is a promising emerging technique in surgical oncology. Ex vivo imaging has high sensitivity, specificity and accuracy for the detection of tumor cells. For broad clinical application in vivo, technical challenges need to be resolved.

Abstract
Purpose: Clear resection margins are paramount for good outcome in children undergoing solid tumor resections. Multiphoton microscopy (MPM) can provide high-resolution, real-time, intraoperative microscopic images of tumor tissue. Objective: This prospective international multicenter study evaluates the diagnostic accuracy, feasibility, and interobserver congruence of MPM in diagnosing solid pediatric tissue and tumors for the first time. Material and methods: Representative fresh sections from six different neonatal solid tissues (liver, lung, kidney, adrenal gland, heart muscle, testicle) and two types of typical pediatric solid tumors (neuroblastoma, rhabdomyosarcoma) with adjacent nonneoplastic tissue were imaged with MPM and then presented online with corresponding H&E stained slides of the exact same tissue region. Both image sets of each tissue type were interpreted by 38 randomly selected international attending pediatric pathologists via an online evaluation software. Results: The quality of MPM was sufficient to make the diagnosis of all normal tissue types except cardiac muscle in >94% of assessors with high interobserver congruence and 95% sensitivity. Heart muscle was interpreted as skeletal muscle in 55% of cases. Based on MPM imaging, participating pathologists diagnosed the presented pediatric neoplasms with 100% specificity, although the sensitivity reached only about 50%. Conclusion: Even without prior training, pathologists are able to diagnose normal pediatric tissues with valuable accuracy using MPM. While current MPM imaging protocols are not yet sensitive enough to reliably rule out neuroblastoma or rhabdomyosarcoma, they seem to be specific and therefore useful to confirm a diagnosis intraoperatively. We are confident that improved algorithms, specific training, and more experience with the method will make MPM a valuable future alternative to frozen section analysis. Registration: The trial was registered at www.researchregistry.com, registration number 2967.

Abstract
BACKGROUND AND PURPOSE Telemedicine is gaining popularity for a variety of indications. We performed a randomized controlled trial comparing telemedical versus conventional clinic follow-up in terms of feasibility and quality. METHODS Patients discharged from pediatric surgery were randomized to telemedical or onsite follow-up. In the telemedical group, video telephony was used to obtain interim history and physical findings. Onsite patients were personally seen in the outpatient clinic. Caregivers completed a postvisit survey on satisfaction and efficiency. Providers scored data transmission quality and clinical interpretability. RESULTS From March 2015 until January 2017, 224 patients were randomized equally to the study groups. Telemedicine was highly accepted by caregivers, and data transmission quality was sufficient for comprehensive follow-up. No important clinical findings were missed. Quality of interaction scored higher in the telemedical versus the onsite group (77.8% vs. 48%, p < 0.001) as did caregiver satisfaction (5.4 vs. 5.1, p < 0.03). Travel investment, time required, loss of earnings, and days off from work/school were all significantly lower in the telemedical group (p < 0.001). CONCLUSIONS Telemedical posthospitalization follow-up in pediatric surgery provides a cost-effective, time-saving alternative for patients and caregivers that is well received and accepted. The quality of clinical data transmission is sufficient to provide safe care and uncompromised clinical judgment. TYPE OF STUDY Prospective and randomized controlled study. LEVEL OF EVIDENCE Level 1b.

Abstract
AIM The aim of the study is to evaluate the impact of pulmonary contusion on the overall outcome in children with multiply injury. PATIENTS AND METHODS Retrospective review of 123 multiply injured children during a 10-year period (January 2000 to February 2010) who were admitted to the intensive care unit of a university affiliated, tertiary care pediatric trauma center. The diagnosis of pulmonary contusion (case group) was defined by the clinical context and the results of chest X-ray and blood gas analysis. Data were compared with a matched control group without the diagnosis of pulmonary contusion. Matching criteria were as follows: (1) age difference within 2 years; (2) sex; (3) similar injury pattern; (4) Pediatric Trauma Score (PTS) difference within 2 points; (5) Glasgow Coma Score (GCS) in two categories. RESULTS The risk of pulmonary contusion must not be underestimated in multiply injured children. In our study, 49 of 123 patients (40%) showed signs of pulmonary contusion. A matched and pair analysis was performed in 46 patients (94%). Pulmonary contusion had an impact on the Pao2/ FIo2 ratio. It was significantly reduced in patients and caused insignificant extension of the ventilation time. Overall length of stay (LOS), LOS at pediatric intensive care unit, complication rate, mortality rate, and short-term outcome did not differ significantly between cases and controls. CONCLUSIONS Pulmonary contusion alters gas exchange but does not appear to increase morbidity and mortality of pediatric patients with multiply injury. Interpretation may be limited by sample size.

Abstract
Hypothermia is increasingly used as a therapeutic strategy in a diversity of clinical scenarios. Its impact on mammalian physiology, particularly on the microcirculatory changes of critical organ systems, are, however, incompletely understood. Close examination of the literature reveals a marked paucity of small animal models of rapid systemic hypothermia. All published models introduce important microvascular confounders by investigating either local cooling processes or using anaesthetised animals. Here we present the first rapid systemic hypothermia model in an awake hamster. We developed a waterstream cooled copper tube system for standardized systemic temperature control. With this novel system core body temperature (Tc) in 14 awake animals could be precisely stabilised at temperatures of 30°C and 18°C (7 animals, respectively) within 10-20 min. Rewarming was achieved over 10-15 min. Tolerance of the procedure was excellent. Hamsters did not show any behavioural changes in the mild hypothermia group. In the deep hypothermia group 6 of 7 animals regained normal behaviour within 2-11 hs. As hypothermia was induced in dorsal skinfold chamber bearing animals this model seems suitable for investigation of microcirculatory purposes.Advantages over previously established experimental hypothermia models are significant. Amongst these, the possibility of visualization of microcirculation, the lack of microcirculation confounding factors such as anaesthetic drugs, the ability for precise Tc control and rapid induction of hypothermia are prominent.

Abstract
INTRODUCTION Funded knowledge about the physiological impact of laparoscopic surgery in children is sparse. Although there are data on hemodynamic compromise after creation of a pneumoperitoneum in children, little is known about microcirculatory changes at the mucosa level. Therefore, the aim of this study was to assess gastric microcirculation by continuous gastric air tonometry in the setting of laparoscopic versus open appendectomy. PATIENTS AND METHODS Twenty children 5-17 years old undergoing laparoscopic and 7 children undergoing open appendectomy were included in the study. Gastric intramucosal CO(2) pressure (pCO(2)i) was measured under standardized flow and intraperitoneal pressure using continuous air tonometry (TONOCAP(®), Datex Ohmeda), and ΔpCO(2) (pCO(2)i - end-expiratory CO(2) pressure [pCO(2)e]) was obtained for the time course of surgery. RESULTS ΔpCO(2) increased significantly from the baseline value not only in the laparoscopic group but also in the open surgery group. Even though ΔpCO(2) was higher in the laparoscopic group at all time points, the overall increase in ΔpCO(2) for both groups was uniform. The largest differences were observed during the initial 20 minutes of the operation. The changes observed were exclusively due to an increase of pCO(2)i in relation to a constant pCO(2)e. DISCUSSION In the setting of a standardized, simple operation in an otherwise healthy child above the age of 5 years, our data suggest that the effect of a pneumoperitoneum on splanchnic perfusion is comparable to the compromise caused by open surgery. Further research must be obtained when evaluating the full impact of laparoscopy in children.

Abstract
UNLABELLED BACKGROUD/PURPOSE: Hirschsprung-associated enterocolitis (HAEC) represents a cause for significant pre- and postoperative morbidity and mortality in Hirschsprung disease (HD). Although multiple studies on HAEC have been performed and several mechanisms have been presumed, the pathogenesis of this condition remains unclear. As changes in colonic mucosal defense are key factors suggested in both Crohn's disease (CD) and HAEC pathogenesis, the aim of the current study was to investigate genetic alterations in the most important susceptibility gene for Crohn's enterocolitis (NOD2) to see whether carriers of polymorphisms within the NOD2 gene are predisposed to the development of HAEC. METHODS Genotyping for the NOD2 variants in exon 4 (p.Arg702Trp [rs2066844]), exon 8 (p.Gly908Arg [rs2066845]), and exon 11 (p.1007fs [rs2066847]) was performed in 52 white children with HD (41 boys, 11 girls), 152 healthy controls, and 152 children with CD (onset of disease <17 years; mean, 11.8 years). Seventeen patients with HD (32.7%) were carriers of a RET germline mutation, 35 children (67.3%) had short segment disease, and 17 (32.7%) had long segment disease. RESULTS Ten children (19.2%) with HD were heterozygous carriers of at least one NOD2 variant vs 17 (11.2%) in the healthy control group and 69 (45.4%) in the CD cohort. Hirschsprung-associated enterocolitis was observed in 7 children (13.5%), with 4 having short segment HD and 3 with long segment HD; but none of them were carriers of NOD2 variants. CONCLUSION Our study shows that NOD2 variants described to be causatively associated with CD do not predispose to the development of HAEC. As data on the molecular basis of HAEC are limited, the distinct mechanisms involved in the pathogenesis of this complication remain unclear.

Abstract
OBJECTIVE Induced hypothermia has been shown to be protective during cardiac surgery, but also in traumatic, ischemic, burn, and neurological injury. In previous in vivo animal experiments, we documented increased leukocyte/endothelial (L/E) cell interaction following normothermic extracorporeal blood circulation (ECC). This study was carried out to investigate whether reduced core temperature during ECC affects the damage to the microcirculation as evidenced by leukocyte adherence and edema formation. METHODS Intravital fluorescence microscopy was used on the dorsal skinfold chamber preparation in Syrian golden hamsters. ECC was introduced via a micro-rollerpump (1 ml/min) and a 60 cm silicon tube (1mm inner diameter) shunted between the carotid artery and the jugular vein after application of 300IE Heparin/kg per body weight. Experiments were performed in chronically instrumented, awake animals (age 10-14 weeks, weight 65-75 g). Animals of the experimental group were cooled to 18 degrees C body temperature while ECC, followed by a rewarming period (n=7), controls experienced ECC under normothermia (37 degrees C, n=7). RESULTS 30 min ECC at 18 degrees C resulted in a decrease of rolling and adherent leucocytes (stickers) in postcapillary venules after 1, 4 and 8h compared with the control group (119+/-46 vs. 274+/-113 n/mm2, P<0.05, mean+/-SD; n=7 in each group). Functional capillary density was significantly reduced during hypothermia (80+/-16 vs. 148+/-16 cm/cm2, P<0.05), but restored after rewarming. In contrast, edema formation was markedly increased during hypothermia. CONCLUSIONS Hypothermia during ECC significantly reduced L/E cell interaction in the early post-ECC period. Hypothermia markedly reduced microvascular perfusion, but was completely restored upon rewarming. Despite a reduced number of adherent leukocytes, no protection of endothelial barrier function was seen as a consequence of induced hypothermia.
