Paediatric Surgery training in South Africa: Trainees' perspectives

Challenges and Innovations in Minimally Invasive Surgery for Pediatric Patients in Africa: A Comprehensive Review

Background

Minimally invasive surgery (MIS) has proven to be a successful, developing improvement in surgical practice. Allowing surgeons to operate with minimal incisions, ensures the completion of such procedures with minimal damage to the patient and provides recovery in a shorter time. The use of MIS in the pediatric population has also been growing with the increased involvement of surgeons in the evaluation of training and expertise. In Africa, however, the growth of MIS in the pediatric population faces some obstacles which are in research and innovation, cost, and affordability. Additionally, to the scarcity of resources, the limited number of pediatric surgeons available leads to a substantial workload that affects the quality of care. This paper aims to evaluate the challenges facing MIS in Africa and assess its potential in the future.

Methods

Data were collected through online databases such as PubMed, Google Scholar, Ovid MEDLINE, and Embase. The research team reviewed all relevant articles regarding MIS in Africa and pediatrics.

Results

The utilization of MIS in the pediatric population in Africa faces some major challenges. In addition to the limited resources, there is a significantly disproportionate number of physicians per population, and the training received by pediatric surgeons rarely incorporates minimally invasive techniques. This leaves a lot of work to be done to allow better access to MIS on the African continent. The recent advances by Africans in minimally invasive and endoscopic surgical training programs, as well as the establishment of minimally invasive centers, show great promise in the attempt to increase the utilization of MIS in Africa.

Conclusions

The work done to grow the field of MIS application in Africa is commendable, but efforts need to be strengthened and focus needs to be given to ensure the sustainability of these programs. Furthermore, the work accomplished by countries like Egypt, Senegal, and Nigeria will serve as a huge teaching point to increase the technical expertise of surgeons in the region.

A review of twenty-first century developments in paediatric surgery in Africa

This review explores the significant advancements in paediatric surgery in Africa during the twenty-first century, with a particular focus on capacity-building, education, infrastructural development, and research. Historically, paediatric surgery has been an overlooked sector, especially in low-and-middle-income countries in Africa. However, recent years have seen considerable progress. Collaborative efforts such as the Global Initiative for Children's Surgery, and the formation of the Pan African Paediatric Surgery Association, the College of Surgeons of East, Central and Southern Africa and the West African College of Surgeons have facilitated knowledge sharing, collaboration, and advocacy for enhancing surgical standards. Local training programmes, including Master of Medicine programmes and fellowships, have been instrumental in building a skilled workforce. These initiatives have been complemented by infrastructural developments through non-governmental organisations like Kids Operating Room, which have expanded access to paediatric surgical care. Technological advancements, particularly in telemedicine, have further enhanced accessibility. Task-sharing strategies, where non-specialist physicians are trained in paediatric surgical skills, have also been utilised to address the shortage of specialised surgeons. Research in paediatric surgery has experienced an upswing, with local health professionals taking the lead. Research has been crucial for understanding the epidemiology of paediatric surgical conditions, and developing prevention strategies, and is increasingly leading to the inclusion of paediatric surgery in national health plans. Despite the progress, challenges remain, including the need for sustainable funding, continued investment in infrastructure, and training and retention of healthcare professionals. The review emphasises the importance of ongoing efforts in community engagement, innovative technologies, and health systems strengthening for the sustainable development of paediatric surgical services in Africa.

A needs assessment for simulation in African surgical education

INTRODUCTION

There is a critical need for comprehensive surgical training in African countries given the unmet surgical burden of disease in this region. Collaborative and progressive initiatives in global surgical education will have the greatest impact on trainees. Little is known about surgical education needs from the perspective of practicing surgeons and trainees in low-middle-income countries (LMICs). Even less is known about the potential role for simulation to augment training.

METHODS

A modified Delphi methodology with 2 rounds of responses was employed to survey program directors (PD) and associate program directors (APD) of Pan-African Association of Christian Surgeons (PAACS) general surgery residency programs across eight low-middle-income countries in Africa. 3 PD/APDs and 2 surgical residents participated in semi-structured interviews centered around the role of simulation in training. Descriptive analysis was performed to elicit key themes and illustrative examples.

RESULTS

The survey of program directors revealed that teaching residents the psychomotor skills need to perform intracorporeal suturing was both high priority and desired in multiple training sites. Other high priority skills were laparoscopic camera driving and medial visceral rotation. The interviews revealed a specific desire to perform laparoscopic surgery and a need for a simulation curriculum to familiarize staff and trainees with laparoscopic techniques. Several barriers to laparoscopic surgery exist, such as lack of staff familiarity with the equipment, lack of public buy in, and lack of generalizable and adaptable educational modules. Trainees saw utility in the use of simulation to optimize time in the operating room and sought opportunities to improve their laparoscopic skills.

CONCLUSION

Faculty and surgical trainees in LMICs have interest in learning advanced surgical techniques, such as laparoscopy. Developing a simulation curriculum tailored to the trainees' local context has the potential to fill this need.

Advances in Pediatric Surgery Simulation-Based Training

Pediatric surgery is the diagnostic, operative, and postoperative surgical care of children with congenital and acquired anomalies and diseases. The early history of the specialty followed the classic "see one, do one, teach one" philosophy of training but has since evolved to modern methods including simulation-based training (SBT). Current trainees in pediatric surgery face numerous challenges, such as the decreasing incidence of congenital disease and reduced work hours. SBT consists of several modalities that together assist in the acquisition of technical skills and improve performance in the operating room. SBT has evolved to incorporate simulator models and video gaming technology, in parallel with the development of simulation in other surgical and non-surgical pediatric fields. SBT has advanced to a level of sophistication that means that it can improve the skills of not only pediatric surgery trainees but also practicing attending surgeons. In this review, we will discuss the history of pediatric surgery, simulation in pediatric surgery training, and the potential direction of pediatric surgical simulation training in the future.

Pre-course instructional videos and home-based laparoscopic suturing simulation enhances the educational impact of a laparoscopic training course

Introduction

We developed a home-based laparoscopic suturing simulation (HBLSS) technique, which is intended to improve the impact of a structured laparoscopic training course.

Method

A group of sixteen students were provided with the educational video, and after two weeks, all students were observed and timed performing a laparoscopic reef knot. The students were then randomized into two cohorts. The exclusive video group continued using the video for a further two weeks. The second group were shown the HBLSS technique and told to use this in conjunction with the video for a further two weeks.

Results

The entire cohort had an initial median time to form an intracorporeal reef knot of 190 s (range 459, IQR 128). After two additional weeks of using the educational video exclusively, the median time was reduced to 85 s (range 282, IQR 125), whereas the HBLSS and educational video group had a median post-training time of 28.5 s (range 36, IQR 18.5). There was a clear statistical difference between the exclusive video group and the HBLSS and video group (P = 0.008). There was also an improvement from the movement of both instruments to one instrument, reduced crossing of instruments and reduced transverse movement in the HBLSS and video group.

Conclusion

A combination of video-based teaching and HBLSS was associated with improved laparoscopic intra-corporeal knot-tying skills in comparison to the exclusive video-based teaching. This reflects the importance of imparting both cognitive and psychomotor skills to students practising laparoscopic surgery.

Developing a novel laparoscopic training model during the Covid-19 pandemic in a resource-limited setting

Background

This paper describes the development and implementation of a unique laparoscopic suturing course in a resource-constrained setting and reviews the initial experience with the program.

Methods

This study describes the development of Grey's laparoscopic suturing course (GLSC) and reviews the questionnaires and feedback over the past year.

Results

The GLSC has been run for over a year and has enrolled 47 participants. Most participants were registrars, followed by consultants and medical officers, and most participants had limited minimal access surgery (MAS) experience. Only three had previously undertaken a formal course or observership. The mean result for the pre-course test was 50%, and for the post-course test, 88%. During the skills laboratory session, every participant competently performed intra-corporeal suturing. The entire group unanimously agreed that the GLSC should be recommended for all surgical trainees in the evaluation form. All participants expressed interest in an advanced MAS course.

Conclusion

We have demonstrated that developing a local MAS suturing course with limited resources and industry support during the Covid 19 pandemic is possible. It has benefited a large group of trainees thus far and hopefully will become part of the curriculum of surgical trainees in South Africa.

Development and Validation of a Laparoscopy Simulation Model of Pyeloplasty for Pediatric Patients

Introduction: Given the extensive training required for laparoscopic pyeloplasty and the difficulties achieving this training, there is a need to recreate the activity in a controlled environment, but high-fidelity models are unavailable or expensive. Our objective was to develop a model of pyeloureteral junction stenosis, resembling the anatomical details and consistency of natural tissue, for a replicable, cheaper, and realistic simulation model of laparoscopic pyeloplasty in children. Materials and Methods: A three-dimensional, printed synthetic model was created from magnetic resonance urography. The model comprises a plastic kidney as the reusable structure and a silicone renal pelvis and ureter as the interchangeable structure. We evaluated realism and performance with surgeons and residents at different levels of training, comparing operative time and complications of the procedure. Results: Twenty-four participants were recruited; 41.7% had previous experience in laparoscopic pyeloplasty, with 5.5 years of experience in laparoscopic surgery (interquartile range [IQR] 2-7.75). There were no cases of stenosis, but leaks accounted for 41.7%. The procedure lasted 72 minutes (IQR 55-90), with significant differences according to the level of training (85 minutes for residents, 68 minutes for pediatric surgeons and urologists, and 40 minutes for laparoscopic surgeons; P: .011) and years of previous experience in laparoscopic surgery (P: .003). Conclusions: A high-fidelity, replicable, and low-cost pyeloureteral stenosis model was developed to simulate laparoscopic pyeloplasty in pediatric patients.

Globalization in Pediatric Surgical Training: The Benefit of an International Fellowship in a Low-to-Middle-Income Country Academic Hospital

OBJECTIVE

 A relative oversupply of pediatric surgeons led to increasing difficulties in surgical training in high-income countries (HIC), popularizing international fellowships in low-to-middle-income countries (LMIC). The aim of this study was to evaluate the benefit of an international fellowship in an LMIC for the training of pediatric surgery trainees from HICs.

METHODS

 We retrospectively reviewed and compared the prospectively maintained surgical logbooks of international pediatric surgical trainees who completed a fellowship at Chris Hani Baragwanath Academic Hospital in the last 10 years. We analyzed the number of surgeries, type of involvement, and level of supervision in the operations. Data are provided in mean differences between South Africa and the respective home country.

RESULTS

 Seven fellows were included. Operative experience was higher in South Africa in general (Δx̅ = 381; 95% confidence interval [CI]: 236-656; p < 0.0001) and index cases (Δx̅ = 178; 95% CI: 109-279; p < 0.0001). In South Africa, fellows performed more index cases unsupervised (Δx̅ = 71; 95% CI: 42-111; p < 0.0001), but a similar number under supervision (Δx̅ = -1; 95% CI: -25-24; p = 0.901). Fellows were exposed to more surgical procedures in each pediatric surgical subspecialty.

CONCLUSION

 An international fellowship in a high-volume subspecialized unit in an LMIC can be highly beneficial for HIC trainees, allowing exposure to higher caseload, opportunity to operate independently, and to receive a wider exposure to the different fields of pediatric surgery. The associated benefit for the local trainees is some reduction in their clinical responsibilities due to the additional workforce, providing them with the opportunity for protected academic and research time.
