Artificial intelligence-aided ultrasound imaging in hepatopancreatobiliary surgery: where are we now?

BACKGROUND: Artificial intelligence (AI) models have been applied in various medical imaging modalities and surgical disciplines, however the current status and progress of ultrasound-based AI models within hepatopancreatobiliary surgery have not been evaluated in literature. Therefore, this review aimed to provide an overview of ultrasound-based AI models used for hepatopancreatobiliary surgery, evaluating current advancements, validation, and predictive accuracies. METHOD: Databases PubMed, EMBASE, Cochrane, and Web of Science were searched for studies using AI models on ultrasound for patients undergoing hepatopancreatobiliary surgery. To be eligible for inclusion, studies needed to apply AI methods on ultrasound imaging for patients undergoing hepatopancreatobiliary surgery. The Probast risk of bias tool was used to evaluate the methodological quality of AI methods. RESULTS: AI models have been primarily used within hepatopancreatobiliary surgery, to predict tumor recurrence, differentiate between tumoral tissues, and identify lesions during ultrasound imaging. Most studies have combined radiomics with convolutional neural networks, with AUCs up to 0.98. CONCLUSION: Ultrasound-based AI models have demonstrated promising accuracies in predicting early tumoral recurrence and even differentiating between tumoral tissue types during and after hepatopancreatobiliary surgery. However, prospective studies are required to evaluate if these results will remain consistent and externally valid.

Robotic hepaticojejunostomy training in novices using robotic simulation and dry-lab suturing (ROSIM): randomized controlled crossover trial.

BACKGROUND: Robotic suturing training is in increasing demand and can be done using suture-pads or robotic simulation training. Robotic simulation is less cumbersome, whereas a robotic suture-pad approach could be more effective but is more costly. A training curriculum with crossover between both approaches may be a practical solution. However, studies assessing the impact of starting with robotic simulation or suture-pads in robotic suturing training are lacking. METHODS: This was a randomized controlled crossover trial conducted with 20 robotic novices from 3 countries who underwent robotic suturing training using an Intuitive Surgical® X and Xi system with the SimNow (robotic simulation) and suture-pads (dry-lab). Participants were randomized to start with robotic simulation (intervention group, n = 10) or suture-pads (control group, n = 10). After the first and second training, all participants completed a robotic hepaticojejunostomy (HJ) in biotissue. Primary endpoint was the objective structured assessment of technical skill (OSATS) score during HJ, scored by two blinded raters. Secondary endpoints were force measurements and a qualitative analysis. After training, participants were surveyed regarding their preferences. RESULTS: Overall, 20 robotic novices completed both training sessions and performed 40 robotic HJs. After both trainings, OSATS was scored higher in the robotic simulation-first group (3.3 ± 0.9 vs 2.5 ± 0.8; p = 0.049), whereas the median maximum force (N) (5.0 [3.2-8.0] vs 3.8 [2.3-12.8]; p = 0.739) did not differ significantly between the groups. In the survey, 17/20 (85%) participants recommended to include robotic simulation training, 14/20 (70%) participants preferred to start with robotic simulation, and 20/20 (100%) to include suture-pad training. CONCLUSION: Surgical performance during robotic HJ in robotic novices was significantly better after robotic simulation-first training followed by suture-pad training. A robotic suturing curriculum including both robotic simulation and dry-lab suturing should ideally start with robotic simulation.

Healthcare cost expenditure for robotic versus laparoscopic liver resection: a bottom-up economic evaluation.

BACKGROUND: Minimally invasive liver surgery (MILS) is increasingly performed via the robot-assisted approach but may be associated with increased costs. This study is a post-hoc comparison of healthcare cost expenditure for robotic liver resection (RLR) and laparoscopic liver resection (LLR) in a high-volume center. METHODS: In-hospital and 30-day postoperative healthcare costs were calculated per patient in a retrospective series (October 2015-December 2022). RESULTS: Overall, 298 patients were included (143 RLR and 155 LLR). Benefits of RLR were lower conversion rate (2.8% vs 12.3%, p = 0.002), shorter operating time (167 min vs 198 min, p = 0.044), and less blood loss (50 mL vs 200 mL, p < 0.001). Total per-procedure costs of RLR (€10260) and LLR (€9931) were not significantly different (mean difference €329 [95% bootstrapped confidence interval (BCI) €-1179-€2120]). Lower costs with RLR due to shorter surgical and operating room time were offset by higher disposable instrumentation costs resulting in comparable intraoperative costs (€5559 vs €5247, mean difference €312 [95% BCI €-25-€648]). Postoperative costs were similar for RLR (€4701) and LLR (€4684), mean difference €17 [95% BCI €-1357-€1727]. When also considering purchase and maintenance costs, RLR resulted in higher total per-procedure costs. DISCUSSION: In a high-volume center, RLR can have similar per-procedure cost expenditure as LLR when disregarding capital investment.

Training in robotic-assisted surgery: a systematic review of training modalities and objective and subjective assessment methods.

INTRODUCTION: The variety of robotic surgery systems, training modalities, and assessment tools within robotic surgery training is extensive. This systematic review aimed to comprehensively overview different training modalities and assessment methods for teaching and assessing surgical skills in robotic surgery, with a specific focus on comparing objective and subjective assessment methods. METHODS: A systematic review was conducted following the PRISMA guidelines. The electronic databases Pubmed, EMBASE, and Cochrane were searched from inception until February 1, 2022. Included studies consisted of robotic-assisted surgery training (e.g., box training, virtual reality training, cadaver training and animal tissue training) with an assessment method (objective or subjective), such as assessment forms, virtual reality scores, peer-to-peer feedback or time recording. RESULTS: The search identified 1591 studies. After abstract screening and full-texts examination, 209 studies were identified that focused on robotic surgery training and included an assessment tool. The majority of the studies utilized the da Vinci Surgical System, with dry lab training being the most common approach, followed by the da Vinci Surgical Skills Simulator. The most frequently used assessment methods included simulator scoring system (e.g., dVSS score), and assessment forms (e.g., GEARS and OSATS). CONCLUSION: This systematic review provides an overview of training modalities and assessment methods in robotic-assisted surgery. Dry lab training on the da Vinci Surgical System and training on the da Vinci Skills Simulator are the predominant approaches. However, focused training on tissue handling, manipulation, and force interaction is lacking, despite the absence of haptic feedback. Future research should focus on developing universal objective assessment and feedback methods to address these limitations as the field continues to evolve.

Hybrid operating room applications for precision hepatobiliary surgery: A narrative review.

This review summarizes the key applications of a hybrid operating room (HOR) in hepatobiliary surgery and explores the advantages, limitations, and future directions of its utilization. A comprehensive literature search was conducted in PubMed to identify articles reporting on the utilization of HORs in liver surgery. So far, the HOR has been limitedly applied in hepatobiliary surgery. It can offer an optimal environment for combining radiological and surgical interventions and for performing image-guided surgical navigation.

Feasibility of same-day discharge after laparoscopic sleeve gastrectomy in the Netherlands.

BACKGROUND: There is a trend towards laparoscopic sleeve gastrectomy (SG) with same-day discharge (SDD), as an efficient healthcare pathway to alleviate the burden on clinical capacity. This approach seems to be safe, if patients are carefully selected. In our bariatric center, a protocol for Roux-en-Y gastric bypass with SDD has already been successfully implemented. The aim of this study was to evaluate feasibility of applying the same SDD protocol for SG. METHODS: A single-center prospective feasibility study was conducted at a high-volume bariatric center. Low-risk patients who were scheduled for primary SG were included. Strict criteria were used for approval upon SDD. The primary outcome was the rate of successful SDD without readmission within 48 h. Secondary outcomes included short-term complications, emergency department visits, readmissions, and mortality. RESULTS: Fifty patients were included in the study, of whom 45 were successfully discharged on the same day of the surgery. Nausea and vomiting were the most common reasons for overnight hospitalization (three patients). One patient was readmitted within the first 48 h due to a mild complication related to bleeding, resulting in a success rate of 88% for SDD without readmission within 48 h. No severe complications or mortality were reported in the cohort. CONCLUSION: Our SDD protocol for SG has demonstrated feasibility, with a high success rate of SDD and no severe complications. Strict conditions should be met for the safe implementation of a SDD protocol, including careful patient selection and the establishment of a safety net to detect early complications.

Two decades of surgical randomized controlled trials: worldwide trends in volume and methodological quality.

BACKGROUND: RCTs are essential in guiding clinical decision-making but are difficult to perform, especially in surgery. This review assessed the trend in volume and methodological quality of published surgical RCTs over two decades. METHODS: PubMed was searched systematically for surgical RCTs published in 1999, 2009, and 2019. The primary outcomes were volume of trials and RCTs with a low risk of bias. Secondary outcomes were clinical, geographical, and funding characteristics. RESULTS: Some 1188 surgical RCTs were identified, of which 300 were published in 1999, 450 in 2009, and 438 in 2019. The most common subspecialty in 2019 was gastrointestinal surgery (50.7 per cent). The volume of surgical RCTs increased mostly in Asia (61, 159, and 199 trials), especially in China (7, 40, and 81). In 2019, countries with the highest relative volume of published surgical RCTs were Finland and the Netherlands. Between 2009 and 2019, the proportion of RCTs with a low risk of bias increased from 14.7 to 22.1 per cent (P = 0.004). In 2019, the proportion of trials with a low risk of bias was highest in Europe (30.5 per cent), with the UK and the Netherlands as leaders in this respect. CONCLUSION: The volume of published surgical RCTs worldwide remained stable in the past decade but their methodological quality improved. Considerable geographical shifts were observed, with Asia and especially China leading in terms of volume. Individual European countries are leading in their relative volume and methodological quality of surgical RCTs.

An RCT is a form of research in which patients are divided randomly into two or more treatment groups to allow a fair and unbiased comparison of both treatments. RCTs are essential in guiding clinical decision-making, but are difficult to perform, especially in surgery. This review assessed the trend in volume and quality of published surgical RCTs over two decades. Surgical RCTs published in 1999, 2009, and 2019 were identified. The main outcome measures were volume of RCTs and trials with a low risk of bias. Different forms of bias can occur when research results are influenced by external factors. Some 1188 surgical RCTs were identified, of which 300 were published in 1999, 450 in 2009, and 438 in 2019. The volume of surgical RCTs published in these years increased mostly in Asia (61, 159, and 199 RCTs), especially in China (7, 40, and 81). In 2019, the countries with highest relative volume of published surgical RCTs were Finland and the Netherlands. Between 2009 and 2019, the proportion of RCTs with a low risk of bias increased from 14.7 to 22.1 per cent (P = 0.004). In 2019, the proportion of trials with a low risk of bias was highest in Europe (30.5 per cent), with the UK and the Netherlands as leaders in this respect. The volume of published surgical RCTs worldwide remained stable in the past decade but their methodological quality improved. Considerable geographical shifts were observed, with Asia and especially China leading in terms of volume. Individual European countries are leading in their relative volume and methodological quality of surgical RCTs.

Evaluation of Postoperative Care Protocol for Roux-en-Y Gastric Bypass Patients with Same-Day Discharge.

INTRODUCTION: Same-day discharge (SDD) after bariatric surgery is increasingly being performed and is safe with careful patient selection. However, detecting early complications during the first postoperative days can be challenging. We developed a postoperative care protocol for these patients and aimed to evaluate its effectiveness in detecting complications and monitoring patient recovery. METHODS: A single-center retrospective observational study was conducted with patients with who underwent Roux-en-Y Gastric Bypass (RYGB) with successful SDD. The study evaluated the effectiveness of the safety net that included simple remote monitoring with a pulsoximeter and thermometer, a phone consultation on postoperative day (POD) 1, and a physical consultation on POD 2-4. Furthermore, an analysis was performed on various factors including pain scores, painkiller usage, and incidences of nausea and vomiting on POD 1. RESULTS: In this study, 373 consecutive patients were included, of whom 19 (5.1%) were readmitted until POD 4. Among these, 12 patients (3.2%) reached out to the hospital themselves, while 7 (1.9%) were readmitted after phone or physical consultations. Ten of the readmitted patients had tachycardia. On POD 1, the mean numeric rating scale was 4 ± 2, and 96.6% of the patients used acetaminophen, 35.5% used naproxen, and 9.7% used oxynorm. Of the patients, 13.9% experienced nausea and 6.7% reported vomiting. CONCLUSION: A postoperative care protocol for SDD after RYGB, comprising simple remote monitoring along with a phone consultation on POD 1 and a physical checkup on POD 2-4, was effective in monitoring patient recovery and detecting all early complications.

Bilaterality, not multifocality, is an independent risk factor for recurrence in low-risk papillary thyroid cancer.

BACKGROUND: The impact of multifocality and bilaterality on recurrence in patients with low-risk papillary thyroid cancer (PTC) is relevant when considering patients for a de-escalated treatment strategy: hemithyroidectomy instead of total thyroidectomy followed with or without radioactive iodine. This study aims to analyze contralateral tumor probability in patients treated for low-risk PTC and assess multifocality and bilaterality as possible predictors for recurrence. METHODS: Patients with low-risk PTC treated with total thyroidectomy followed with or without radioactive iodine in the Netherlands between 2005 and 2015 were included in this study. Patients were identified from the Netherlands Comprehensive Cancer Organization (IKNL) and linked with the nationwide network and registry of Pathology in the Netherlands (PALGA). Contralateral tumor probability and recurrence were assessed. RESULTS: Of 791 included patients, 41.8% (331 of 791) had multifocal disease, with 68.9% (228 of 331) of those patients having bilateral disease. The contralateral tumor probability after hemithyroidectomy was 24.6% (150 of 610) for patients with unifocal disease and 43.1% (78 of 181) for patients with multifocal disease. We found a higher trend of recurrence in patients with bilateral disease, regardless of multifocality: in patients with contralateral disease after precompletion diagnosed unifocal disease 7.3% (11 of 150) had recurrent disease, and patients without contralateral disease after precompletion diagnosed multifocal disease 1.9% (2 per 103) had recurrence. Cox regression analysis showed that bilaterality (hazard ratio = 3.621, 95% confidence interval = 1.548 to 8.471) was the sole statistically significant risk factor for recurrence. CONCLUSION: Low recurrence rates are found in patients with either multifocal or bilateral disease with low-risk PTC. Bilaterality should be taken into account when considering these patients for de-escalated treatment strategy.

Objective measurement of retention of laparoscopic skills: a prospective cohort study.

INTRODUCTION: There has been an overall growth of 462% in laparoscopic procedures performed by surgical residents between 2000 and 2018. Therefore, training courses in laparoscopic surgery are advocated in many postgraduate programs. While the immediate effect is determined in some cases, the retention of acquired skills is rarely investigated. The objective of this study was to objectively measure the retention of laparoscopic technical skills to offer a more personalized training program. METHODS: First year general surgery residents performed two fundamental laparoscopic skills tasks (Post and Sleeve and the ZigZag loop) on the Lapron box trainer. Assessment was performed before, directly after, and 4 months after completing the basic laparoscopy course. Force, motion, and time were the measured variables. RESULTS: A total of 29 participants were included from 12 Dutch training hospitals and 174 trials were analyzed. The 4 months assessment of the Post and Sleeve showed a significant improvement in force ( P= 0.004), motion ( P ≤0.001), and time ( P ≤0.001) compared to the baseline assessment. The same was true for the ZigZag loop: force ( P ≤0.001), motion ( P= 0.005), and time ( P ≤0.001).Compared to the 4 months assessment, skill deterioration was present for the Post and Sleeve in the mean force ( P= 0.046), max impulse ( P= 0.12), and time ( P= 0.002). For the ZigZag loop, skill decay was observed for force ( P= 0.021), motion ( P= 0.015), and time ( P ≤0.001) parameters. CONCLUSION: Acquired laparoscopic technical skills decreased 4 months after the basic laparoscopy course. Compared to baseline performance, participants showed significant improvement, however deterioration was observed compared to postcourse measurements. To preserve acquired laparoscopic skills, it is recommended to incorporate maintenance training, preferably with objective parameters, in training curricula.

Predictors of improved psychological function after bariatric surgery.

BACKGROUND: Negative psychological sequelae have been reported after bariatric surgery. It is unclear which factors affect psychological function in the first postoperative years. OBJECTIVE: Evaluation of significant predictors of improved psychological function following bariatric surgery by analyzing data from the BODY-Q questionnaire. SETTING: Multicenter prospective cohort in 3 centers located in The Netherlands and Denmark. METHODS: The BODY-Q questionnaire was used to assess 6 domains of health-related quality of life. The domain of interest, psychological function, consists of 10 questions from which a converted score of 0 (low) to 100 (high) can be calculated. Linear mixed models were used to analyze which patient characteristics were most predictive of the psychological function score. Secondary outcomes of interest were cross-sectional scores of psychological function and the impact of weight loss, and the effect of major short-term complications on psychological function. RESULTS: Data were analyzed from 836 patients who underwent bariatric surgery from 2015 to 2020. Patients with lower expectations concerning weight loss (<40% desired total weight loss), higher educational level, no history of psychiatric illness, and employment before bariatric surgery demonstrated the highest psychological function scores after bariatric surgery. At 1 and 2 years after bariatric surgery, more weight loss was associated with significantly higher psychological function scores. Experiencing a major short-term complication did not significantly impact psychological function. CONCLUSIONS: Several relevant predictors of improved postoperative psychological function have been identified. This knowledge can be used to enhance patient education preoperatively and identify patients at risk for poor psychological functioning postoperatively.

Same-Day Discharge After Laparoscopic Roux-en-Y Gastric Bypass: a Cohort of 500 Consecutive Patients.

INTRODUCTION: There is an increasing demand on hospital capacity worldwide due to the COVID-19 pandemic and local staff shortages. Novel care pathways have to be developed in order to keep bariatric and metabolic surgery maintainable. Same-day discharge (SDD) after laparoscopic Roux-en-Y gastric bypass (RYGB) is proved to be feasible and could potentially solve this challenge. The aim of this study was to investigate whether SDD after RYGB is safe for a selected group of patients. METHODS: In this single-center cohort study, low-risk patients were selected for primary RYGB with intended same-day discharge with remote monitoring. All patients were operated according to ERAS protocol. There were strict criteria on approval upon same-day discharge. It was demanded that patients should contact the hospital in case of any signs of complications. Primary outcome was the rate of successful same-day discharge without readmission within 48 h. Secondary outcomes included short-term complications, emergency department visits, readmissions, and mortality. RESULTS: Five hundred patients underwent RYGB with intended SDD, of whom 465 (93.0%) were successfully discharged. Twenty-one patients (4.5%) were readmitted in the first 48 h postoperatively. None of these patients had a severe bleeding. This results in a success rate of 88.8% of SDD without readmission within 48 h. CONCLUSIONS: Same-day discharge after RYGB is safe, provided that patients are carefully selected and strict discharge criteria are used. It is an effective care pathway to reduce the burden on hospital capacity.

A Decision Aid to Help Patients Make Informed Choices Between the Laparoscopic Gastric Bypass or Sleeve Gastrectomy.

PURPOSE: In the Netherlands, patients can often choose between the laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) as primary bariatric surgery. Yet, patients confronted with medical options may experience decisional conflict when their stakes are high and outcomes uncertain. This study aimed to assess if a decision aid helps patients make informed choices between two bariatric procedures by lowering the level of decisional conflict. MATERIALS AND METHODS: This study was a single-center comparative cohort of patients who accessed a web-based decision aid (intervention group) and those who did not use the decision aid (control group) to help choose between two bariatric procedures additional to the standard provided care. The primary outcome was the level of decisional conflict in these patients using the decisional conflict scale (DCS). Secondary outcomes were patient satisfaction with the provided information (BODY-QTM-satisfaction with information), preference of involvement in procedure selection, level of shared decision-making (SDM-Q-9 questionnaire), and patient knowledge. RESULTS: The level of decisional conflict assessed with the decisional conflict scale (DCS) showed a significantly lower mean total DCS of 25.5 ± 11.5 for the intervention group vs. 29.1 ± 12.4 in the control group (p = 0.022). Both groups did not significantly differ in satisfaction regarding provided information, involvement in the selection procedure, shared decision-making, and patient knowledge. CONCLUSION: The results suggest that the additional use of a decision aid significantly lowers the level of decisional conflict in patients awaiting bariatric surgery. However, the added value should be further investigated.

Inguinal hernia surgery learning curves by associate clinicians.

BACKGROUND: Open inguinal hernia repair is the most commonly performed procedure in general surgery in sub-Saharan Africa, but data on its learning curve are lacking. This study evaluated the learning curve characteristics to improve surgical training and enable scaling up hernia surgery in low- and middle-income countries. METHODS: Logbook data of associate clinicians enrolled in a surgical training program in Sierra Leone were collected and their first 55 hernia surgeries following the Bassini technique (herniorrhaphies) were analyzed in cohorts of five cases. Studied variables were gradient of decline of operating time, variation in operating time, and length of stay (LOS). Eleven subsequent cohorts of each five herniorrhaphies were investigated. RESULTS: Seventy-five trainees enrolled in the training program between 2011 and 2020 were eligible for inclusion. Thirty-one (41.3%) performed the minimum of 55 herniorrhaphies, and had also complete personal logbook data. Mean operating times dropped from 79.6 (95% CI 75.3-84.0) to 48.6 (95% CI 44.3-52.9) minutes between the first and last cohort, while standard deviation in operating time nearly halved to 15.4 (95% CI 11.7-20.0) minutes, and LOS was shortened by 3 days (8.5 days, 95%CI 6.1-10.8 vs. 5.4 days, 95% 3.1-7.6). Operating times flattened after 31-35 cases which corresponded with 1.5 years of training. CONCLUSIONS: The learning curve of inguinal hernia surgery for associate clinicians flattens after 31-35 procedures. Training programs can be tailored based on this finding. The recorded learning curve may serve as a baseline for future training techniques.

Machine learning applications in upper gastrointestinal cancer surgery: a systematic review.

BACKGROUND: Machine learning (ML) has seen an increase in application, and is an important element of a digital evolution. The role of ML within upper gastrointestinal surgery for malignancies has not been evaluated properly in the literature. Therefore, this systematic review aims to provide a comprehensive overview of ML applications within upper gastrointestinal surgery for malignancies. METHODS: A systematic search was performed in PubMed, EMBASE, Cochrane, and Web of Science. Studies were only included when they described machine learning in upper gastrointestinal surgery for malignancies. The Cochrane risk-of-bias tool was used to determine the methodological quality of studies. The accuracy and area under the curve were evaluated, representing the predictive performances of ML models. RESULTS: From a total of 1821 articles, 27 studies met the inclusion criteria. Most studies received a moderate risk-of-bias score. The majority of these studies focused on neural networks (n = 9), multiple machine learning (n = 8), and random forests (n = 3). Remaining studies involved radiomics (n = 3), support vector machines (n = 3), and decision trees (n = 1). Purposes of ML included predominantly prediction of metastasis, detection of risk factors, prediction of survival, and prediction of postoperative complications. Other purposes were predictions of TNM staging, chemotherapy response, tumor resectability, and optimal therapy. CONCLUSIONS: Machine Learning algorithms seem to contribute to the prediction of postoperative complications and the course of disease after upper gastrointestinal surgery for malignancies. However, due to the retrospective character of ML studies, these results require trials or prospective studies to validate this application of ML.

Prediction of laparoscopic skills: objective learning curve analysis.

INTRODUCTION: Prediction of proficiency of laparoscopic skills is essential to establish personalized training programs. Objective assessment of laparoscopic skills has been validated in a laparoscopic box trainer with force, motion and time recognition. The aim of this study is to investigate whether acquiring proficiency of laparoscopic skills can be predicted based on performance in such a training box. METHODS: Surgical residents in their first year of training performed six different tasks in the Lapron box trainer. Force, motion and time data, three objective measures of tissue manipulation and instrument handling, were collected and analyzed for the six different tasks. Linear regression tests were used to predict the learning curve and the number of repetitions required to reach proficiency. RESULTS: A total of 6010 practice sessions performed by 42 trainees from 13 Dutch hospitals were assessed and included for analysis. Proficiency level was determined as a mean result of seven experts performing 42 trials. Learning curve graphs and prediction models for each task were calculated. A significant relationship between force, motion and time during six different tasks and prediction of proficiency was present in 17 out of 18 analyses. CONCLUSION: The learning curve of proficiency of laparoscopic skills can accurately be predicted after three repetitions of six tasks in a training box with force, path length and time recognition. This will facilitate personalized training programs in laparoscopic surgery.

PREvalence Study on Surgical COnditions (PRESSCO) 2020: A Population-Based Cross-Sectional Countrywide Survey on Surgical Conditions in Post-Ebola Outbreak Sierra Leone.

BACKGROUND: Understanding the burden of diseases requiring surgical care at national levels is essential to advance universal health coverage. The PREvalence Study on Surgical COnditions (PRESSCO) 2020 is a cross-sectional household survey to estimate the prevalence of physical conditions needing surgical consultation, to investigate healthcare-seeking behavior, and to assess changes from before the West African Ebola epidemic. METHODS: This study (ISRCTN: 12353489) was built upon the Surgeons Overseas Surgical Needs Assessment (SOSAS) tool, including expansions. Seventy-five enumeration areas from 9671 nationwide clusters were sampled proportional to population size. In each cluster, 25 households were randomly assigned and visited. Need for surgical consultations was based on verbal responses and physical examination of selected household members. RESULTS: A total of 3,618 individuals from 1,854 households were surveyed. Compared to 2012, the prevalence of individuals reporting one or more relevant physical conditions was reduced from 25 to 6.2% (95% CI 5.4-7.0%) of the population. One-in-five conditions rendered respondents unemployed, disabled, or stigmatized. Adult males were predominantly prone to untreated surgical conditions (9.7 vs. 5.9% women; p < 0.001). Financial constraints were the predominant reason for not seeking care. Among those seeking professional health care, 86.7% underwent surgery. CONCLUSION: PRESSCO 2020 is the first surgical needs household survey which compares against earlier study data. Despite the 2013-2016 Ebola outbreak, which profoundly disrupted the national healthcare system, a substantial reduction in reported surgical conditions was observed. Compared to one-time measurements, repeated household surveys yield finer granular data on the characteristics and situations of populations in need of surgical treatment.

Approaches to Surgical Debridement in Necrotizing Soft Tissue Infections: Outcomes of an Animated, Interactive Survey.

BACKGROUND: Necrotizing soft tissue infections (NSTI) affect long-term quality of life in survivors. Different approaches to debridement may influence quality of life. The aim of this study was to assess the current practice of the debridement of NSTI in the Netherlands. METHODS: An animated, interactive online survey was distributed among general surgeons and plastic surgeons in the Netherlands. Two NSTI-cases were presented, followed by questions regarding the preferred surgical approach. Case one described a woman with a swollen, red leg, with signs of sepsis and without visible necrosis. Case two described an immunocompromised man with septic shock syndrome and extensive necrosis. RESULTS: In total 232 responses were included (143 general surgeons, 89 plastic surgeons). In case one, 32% chose to preserve all skin, while 17% chose to resect all skin above the affected fascia, including normal-looking skin. In case two, all participants resected necrotic skin, and most (88%) also blue discolored skin. While 32% did not resect more than blue discolored and necrotic skin, 35% also resected red-colored skin, and 21% all skin overlying the affected fascia, including normal colored skin. Respondents working in a hospital with a burn center tended to preserve more skin, whereas plastic surgeons chose more often for skin resection compared to general surgeons. CONCLUSIONS: By using a novel approach to a survey, the authors demonstrate the existence of extensive practice variety regarding the approach to debridement of NSTI among Dutch general and plastic surgeons. Consensus is needed, followed by targeted education of surgeons.

Implementing an enhanced recovery after thoracic surgery programme in the Netherlands: a qualitative study investigating facilitators and barriers for implementation.

OBJECTIVES: This study aims to elucidate determinants for succesful implementation of the Enhanced Recovery After Thoracic Surgery (ERATS) protocol for perioperative care for surgical lung cancer patients in the Netherlands. SETTING: Lung cancer operations are performed in both academic and regional hospitals, either by cardiothoracic or general thoracic surgeons. Limiting the impact of these operations by optimising and standardising perioperative care with the ERATS protocol is thought to enable reduction in length of stay, complications and costs. PARTICIPANTS: A broad spectrum of stakeholders in perioperative care for patients with lung resection participated in this study, ranging from patient representatives, healthcare professionals to an insurance company representative. INTERVENTIONS: Semistructured interviews (N=14) were conducted with the stakeholders (N=18). The interviews were conducted one on one by telephone and two times, face to face, in small groups. Verbatim transcriptions of these interviews were coded for the purpose of thematic analysis. OUTCOME MEASURES: Determinants for successful implementation of the ERATS protocol in the Netherlands. RESULTS: Several determinants correspond with previous publications: having a multidisciplinary team, leadership from a senior clinician and support from an ERAS-coordinator as facilitators; lack of feedback on performance and absence of management support as barriers. Our study underscores the potential detrimental effect of inconsistent communication, the lack of support in the transition from hospital to home and the barrier posed by lack of accessible audit data. CONCLUSIONS: Based on a structured problem analysis among a wide selection of stakeholders, this study provides a solid basis for choosing adequate implementation strategies to introduce the ERATS protocol in the Netherlands. Emphasis on consistent and sufficient communication, support in the transition from hospital to home and adequate audit and feedback data, in addition to established implementation strategies for ERAS-type programmes, will enable a tailored approach to implementation of ERATS in the Dutch context.

Does livestreaming surgical education have the future? Development and participant evaluation of a national COVID-19 livestreaming initiative.

BACKGROUNDS: COVID-19 related reduction of surgical procedures jeopardizes learning on the job of surgical residents. Many educators resorted to digital resources in the search for alternatives. However, these resources are often limited to the extent they offer resident-surgeon interaction like a joint surgical performance does. Here we present a roadmap of livestreaming surgical procedures, and evaluate how surgical livestreams on human cadavers address the unmet educational needs of surgical residents in our Dutch nationwide initiative. METHODS: Technical and organizational feasibility, and definition of outcome deliverables for the livestream series and per livestream were essential in livestream development. Faculty selected interventions, lecture contents, and participant preparations. Appropriate location, technical setup, and support were imperative for a stable, high-quality stream with integrated interaction, while maintaining digital privacy. A survey was sent to livestream participants to evaluate each livestream, and allow for constant improvement during the broadcasting of the series. Only surveys which were completed by surgical residents were included in the analysis of this study. RESULTS: Each livestream attracted 139-347 unique viewers and a total of 307 surveys were completed by participants (response rate of 23-38% per livestream). Sixty percent of surveys (n = 185) were completed by surgical residents. Livestreams were highly valued (appreciation 7.7 ± 1.1 and recommendation 8.6 ± 1.1), especially the live procedures combined with interaction and theoretical backgrounds. Criticized were technical difficulties and timing of the livestreams between 5 and 7 pm, which interfered with clinical duties. CONCLUSION: Livestreaming surgical procedures on human cadavers is a valid and valued solution to augment resident education. Digital privacy and a stable, high-quality interactive stream are essential, as are appropriate moderation and relevant lectures. While livestreaming cannot replace hands-on training in the operating room, it enables surgeon-resident interaction which is key in education-and missed in pre-recorded surgical procedures which are currently available online.
