Purpose: To define the spectrum of management for thoracic empyema in children in Australia and New Zealand.Methods: Online survey of members of the Australian and New Zealand Association of Paediatric Surgeons (ANZAPS), limited to consultant/attending paediatric surgeons.Results: A total of 54/80 (67.5%) members, from 16 paediatric surgical centres, responded. The majority (33/54, 61%) preferred chest drain with fibrinolytics, whilst 21/54 (39%) preferred video-assisted thoracoscopic surgery (VATS) with drain insertion. Urokinase was the most commonly used fibrinolytic (64%). There were no significant differences in management preferences between practising surgeons in Australia and New Zealand (p = 0.54), nor between consultants who had been practising a shorter (< 5 years) or longer (> 20 years) amount of time (p = 0.21). The practices described by the surveyed ANZAPS members were in line with the Thoracic Society of Australia and New Zealand recommendations for the management of paediatric empyema.Conclusion: Across Australia and New Zealand there exists significant variation surrounding the intra- and post-intervention management of thoracic empyema in children. The surveyed paediatric surgeons demonstrated a preference for fibrinolytics over the use of VATS. All management regimens were within published local guidelines. [ABSTRACT FROM AUTHOR]

Evaluation is a vital part of any learning activity and is essential to optimize and improve educational programmes. It should be considered and prioritized prior to the implementation of any learning activity. However, comprehensive programme evaluation is rarely conducted, and there are numerous barriers to high‐quality evaluation. This review provides a framework for conducting outcome evaluation of simulation‐based education programmes in low and middle‐income countries (LMICs). The basis of evaluation, including core ideas of theory, purpose and structure are outlined, followed by an examination of the levels and healthcare applications of the Kirkpatrick model of evaluation. Then, methods of conducting evaluation of simulation‐based education in LMICs are discussed through the lens of a successful surgical simulation programme in Myanmar, a lower‐middle‐income country. The programme involved the evaluation of 11 courses over 4 years in Myanmar and demonstrated evaluation at the highest level of the Kirkpatrick model. Reviewing this programme provides a bridge between evaluation theory and practical implementation. A range of evaluation methods are outlined, including surveys, interviews, and clinical outcome measurement. The importance of a mixed‐methods approach, enabling triangulation of quantitative and qualitative analysis, is highlighted, as are methods of analysing data, including statistical and thematic analysis. Finally, issues and challenges of conducting evaluation are considered, as well as strategies to overcome these barriers. Ultimately, this review informs readers about evaluation theory and methods, grounded in a practical application, to enable other educators in low‐resource settings to evaluate their own activities.

• We proposed to use an innovative CNN-LSTM network to objectively classify surgical skills levels. • One open surgery dataset and one RMIS dataset were used to evaluate the performance of the proposed method. • Accelerometers provided a better accuracy compared to gyroscopes. • Higher accuracy achieved when added SENet block and restart learning rate to the CNN-LSTM network. Currently, the assessment of surgical skills relies primarily on the observations of expert surgeons. This may be time-consuming, non-scalable, inconsistent and subjective. Therefore, an automated system that can objectively identify the actual skills level of a junior trainee is highly desirable. This study aims to design an automated surgical skills evaluation system. We propose to use a deep neural network model that can analyze raw surgical motion data with minimal preprocessing. A platform with inertial measurement unit sensors was developed and participants with different levels of surgical experience were recruited to perform core open surgical skills tasks. JIGSAWS a publicly available robot based surgical training dataset was used to evaluate the generalization of our deep network model. 15 participants (4 experts, 4 intermediates and 7 novices) were recruited into the study. The proposed deep model achieved an accuracy of 98.2%. With comparison to JIGSAWS; our method outperformed some existing approaches with an accuracy of 98.4%, 98.4% and 94.7% for suturing, needle-passing, and knot-tying, respectively. The experimental results demonstrated the applicability of this method in both open surgery and robot-assisted minimally invasive surgery. This study demonstrated the potential ability of the proposed deep network model to learn the discriminative features between different surgical skills levels. [ABSTRACT FROM AUTHOR]

Circumcision is one of the most commonly performed surgical procedures in the world. Despite this, the practice of paediatric circumcision remains highly controversial, and continues to generate ongoing debate. This debate has become more relevant recently with the provisional guidelines from the Centers for Disease Control and Prevention recommending a change of practice. In this review article, we provide an overview of the history and incidence of circumcision, normal preputial development, types of phimosis, the absolute and relative indications for circumcision as well as the evidence base for its use as a preventative measure. Our aim is to provide paediatricians with a greater understanding of this common surgical procedure and the conditions it treats, to guide their clinical practice and parent counselling.

Background: Paediatric laparoscopic procedures are now becoming routine practice. Therefore, there is a need for simulated laparoscopic models to acquire part-procedural competency prior to direct patient contact in a safe learning environment. For this reason, we chose two paediatric conditions; inguinal hernia (IH) and congenital diaphragmatic hernia (CDH), which were combined to create the laparoscopic inguinal and diaphragmatic defect (LIDD) model. Our aim was to assess this novel surgical simulation model by determining its construct and content validity.Methods: A total of 107 participants completed the validation study: volunteer medical students (novices), surgical trainees (intermediate) and consultant surgeons (experts). Basic demographic data were collected. Subjects were shown a pre-recorded video of both exercises. The assessment exercise involved closing both the simulated inguinal or diaphragmatic hernial orifice. The task was assessed using a novel scoring system with a maximum score of 21 for IH model and 15 for the CDH. The content validity was assessed by a 6-point Likert scale of the expert group.Results: 105/107 participants successfully completed the two exercises. Both aspects of the LIDD model revealed a statistical significance between the scores obtained by the three groups of subjects. Experts scored 20.3/21 for the IH and 14.8/15 for the CDH models which significantly higher than medical students (6.3/21 and 5.3/15; p < 0.05 for both) and trainees (11.2/21 and 9.3/15; p < 0.05 for both). Similarly, trainees performed significantly better than medical students in both models (p < 0.05). Therefore, the LIDD model was found to have a good construct validity. It was, however, unable to differentiate between the various levels of trainees in the intermediate group. Content validity from the experts revealed that there was a high score for the potential of both aspects of LIDD (4.8 and 4.8). There was also a high level of functional fidelity for task completion (4.0 and 4.0).Conclusions: We have demonstrated both the construct and content validity of the LIDD model for both laparoscopic IH and CDH repair. It was able to successfully differentiate between the expert, trainees and inexperienced laparoscopic surgeons. [ABSTRACT FROM AUTHOR]

Aim: To analyse the characteristics of patients with choledochal cysts presenting with acute pancreatitis.Methods: Multicenter retrospective review of all paediatric patients (<18 years) with choledochal cysts managed over a 14-year period (2001-2014) at two tertiary paediatric surgical centres. Patient data were analysed for demographics, presentation, radiological classification of cyst type (Todani), operative interventions, complications and long-term follow-up.Results: A total of 49 patients with choledochal cysts were identified with 15 (31%) being Type I fusiform, 18 (37%) Type I cystic and 16 (32%) Type IV-A. Seventeen (35%) patients presented with acute pancreatitis, one having had an ante-natally diagnosed choledochal cyst. Patients presenting with pancreatitis were older when compared to the non-pancreatitis group (5.1 vs. 1.2 years, P = 0.005). Nine out of 16 (53%) patients with Type IV-A cysts presented with pancreatitis compared to five (33%) of Type I fusiform and three (17%) of Type I cystic. There was however no statistically significant association between Todani types and the development of pancreatitis (Type I fusiform, P = 1.0; Type I cystic, P = 0.063; Type IV-A, P = 0.053). The rate of complications was similar in both groups.Conclusion: Pancreatitis was a common presentation in children with a choledochal cyst, however, there was no clear statistically significant association with Todani types and pancreatitis.

Background: Simulation‐based medical education (SBME) is an integral part of undergraduate and postgraduate training in high‐income countries (HICs). Despite potential benefits to low‐ and middle‐income countries (LMICs), it has not been widely applied. Our aim was to use SBME to address some essential paediatric surgery learning needs in a LMIC. Methods: Eleven SBME courses were designed, implemented and evaluated over a 4‐year period in partnership with local paediatric surgeons and the University of Medicine 1 in Yangon, Myanmar. All courses were simulation‐based and different major SBME modalities were utilized. Evaluation included pre‐ and post‐course questionnaires, other evaluation assessments including Likert scale self‐rated confidence in different domains, as well as, mixed method evaluation and Kirkpatrick's hierarchy of evaluation. Results: Over 4 years, a multidisciplinary team consisting of surgical consultants, fellows, and educational specialists delivered 11 courses at a tertiary LMIC paediatric surgical centre. Attendance varied between 23 and 50 healthcare professionals, with some participants attending all of the educational activities. SBME modalities were utilized to meet each courses' learning objectives. All educational courses scored highly and showed statistically significant differences in all the self‐rated pre and post‐course confidence Likert scale domains. SBME was accepted and embraced by local participants and faculty, and transition to local delivery of educational content has begun. Level 4 of Kirkpatrick's hierarchy of evaluation was demonstrated. Conclusion: SBME can be used to meet essential learning objectives of local staff in a LMIC. Through various modalities, it offers a reliable, proven and affordable means of teaching multiple aspects of paediatric surgical clinical practice. By employing innovative simulation‐based solutions, it can be adapted by local faculty to continue meeting ongoing learning needs. [ABSTRACT FROM AUTHOR]

Background: In contrast to many countries, the prevalence of COVID‐19 in Australia and New Zealand has been low. We hypothesised, however, that a potential secondary effect of the COVID‐19 pandemic would be delayed presentation of paediatric appendicitis, with resultant higher rates of complicated appendicitis. This study was an initiative of the Australian and New Zealand Surgery in Children Registrars' Association for Trials collaborative, a trainee‐led research group based in Australia and New Zealand. Methods: A binational multicentre, retrospective review was undertaken of paediatric patients with appendicitis early in the COVID‐19 pandemic (20 March–30 April 2020), compared with previous years (2018, 2019). Primary outcomes were the duration of symptoms prior to presentation and the severity of disease. Results: A total of 400 patients from six centres were included. Duration of symptoms prior to presentation, sepsis at presentation, complicated disease and presence of complications did not differ significantly between time periods. Duration of intravenous antibiotic treatment and overall antibiotic treatment were both significantly shorter during 2020 (2.4 days versus 3.5 in 2018 and 3.0 in 2019 [P = 0.0038] and 3.7 days versus 5.2 in 2018 and 4.6 in 2019 [P = 0.04], respectively). Management approach did not differ, with the majority of patients managed operatively. Conclusions: We did not demonstrate any difference in duration of symptoms prior to presentation or other markers of disease severity early in the pandemic. Duration of antibiotic treatment was shorter during this period compared with previous years. Management of children with appendicitis, both simple and complicated, did not appear to change as a result of COVID‐19. [ABSTRACT FROM AUTHOR]
