Mentorship and formal robotic proficiency skills curriculum improve subsequent generations' learning curve for the robotic distal pancreatectomy

Residency robotic biotissue curriculum: the next frontier in robotic surgical training

INTRODUCTION

Virtual reality has been shown to be a strong introduction to the robot. However, we hypothesized that a biotissue curriculum including common surgical anastomoses can further enhance robotic technical skills in surgical residents.

METHODS

Post-graduate-year three (PGY-3) general surgery residents completed a two-week robotic simulation rotation. The inanimate exercises used biotissue to simulate common robotic anastomoses, including the running hepaticojejunostomy (RHJ), gastrojejunostomy (GJ), interrupted hepaticojejunostomy (IHJ), and pancreaticojejunostomy (PJ). Drills were timed and graded according to modified Objective Structured Assessment of Technical Skills (OSATS; range 6-30).

RESULTS

32 residents completed the curriculum. 81.3% of residents reported prior experience at the surgeon console (median=5 operations). Across all drills the average time to completion decreased from first to fourth attempt (RHJ: 33.7±8.9 vs. 26.3±8.1 min, p<0.001; GJ: 57.2±15.1 vs. 44.6±9.5 min, p<0.001; IHJ: 32.6±7.2 vs. 27.1±7.7 min, p<0.001; PJ: 44.2±9.3 vs. 35.6±10.5 min, p<0.001). Average OSATS score increased across all drills as well (RHJ: 16.0±3.8 vs. 23.3±3.4, p<0.001; GJ: 19.4±2.1 vs. 26.0±2.5, p<0.001; IHJ: 16.9±2.7 vs. 23.2±3.6, p<0.001, PJ: 17.9±2.6 vs. 23.6±3.6, p<0.001).

CONCLUSION

The robotic biotissue curriculum improves resident performance on robotic anastomoses. With the rise of the robotic platform, training in robotic procedures should be incorporated during surgical residency.

Essential components and validation of multi-specialty robotic surgical training curricula: a systematic review

INTRODUCTION

The rapid adoption of robotic surgical systems has overtook the development of standardized training and competency assessment for surgeons, resulting in an unmet educational need in this field. This systematic review aims to identify the essential components and evaluate the validity of current robotic training curricula across all surgical specialties.

METHODS

A systematic search of MEDLINE, EMBASE, Emcare, and CINAHL databases was conducted to identify the studies reporting on multi-specialty or specialty-specific surgical robotic training curricula, between January 2000 and January 2024. We extracted the data according to Kirkpatrick's curriculum evaluation model and Messick's concept of validity. The quality of studies was assessed using the Medical Education Research Study Quality Instrument (MERSQI).

RESULTS

From the 3687 studies retrieved, 66 articles were included. The majority of studies were single-center ( n = 52, 78.8%) and observational ( n = 58, 87.9%) in nature. The most commonly reported curriculum components include didactic teaching ( n = 48, 72.7%), dry laboratory skills ( n = 46, 69.7%), and virtual reality (VR) simulation ( n = 44, 66.7%). Curriculum assessment methods varied, including direct observation ( n = 44, 66.7%), video assessment ( n = 26, 39.4%), and self-assessment (6.1%). Objective outcome measures were used in 44 studies (66.7%). None of the studies were fully evaluated according to Kirkpatrick's model, and five studies (7.6%) were fully evaluated according to Messick's framework. The studies were generally found to have moderate methodological quality with a median MERSQI of 11.

CONCLUSIONS

Essential components in robotic training curricula identified were didactic teaching, dry laboratory skills, and VR simulation. However, variability in assessment methods used and notable gaps in curricula validation remain evident. This highlights the need for standardized evidence-based development, evaluation, and reporting of robotic curricula to ensure the effective and safe adoption of robotic surgical systems.

Scoping review and proposed curriculum for robotic hepatopancreatobiliary surgery training

BACKGROUND

HPB surgery is being increasingly performed robotically worldwide. However, there is no consensus on what constitutes adequate training or an established curriculum. We evaluate the existing literature on formal education in robotic hepatopancreaticobiliary (HPB) surgery and propose a curriculum using Kern's six-step curriculum development model.

METHODS

A systematic search was performed across major databases and the methodology of the Joanna Briggs Institute was followed. The PRISMA-ScR was conformed in reporting. Evidence pertaining to cholecystectomy alone was excluded and studies that described formal training pathways were included.

RESULTS

Fifteen curricula were included with predilection towards the pancreas (n = 7, liver: n = 5, combination: n = 3). Almost all studies proposed initial robot system training through online modules, observership and console simulation exercises. Following this, six curricula described procedure-specific anastomosis training. Almost all studies described mentorship and proctorship. The assessment for implementation commonly described includes objective structured assessment of technical skill (OSATS) and cumulative sum technique (CUSUM) for operation time, conversion-to-open rate and postoperative complications.

DISCUSSION

This study has summarised the formal curricula for learning robotic HPB surgery. The majority share similar implementation tools. A comprehensive curriculum based on validated educational principles has been proposed which incorporates these elements.

Video Review Can Measure Surgical Robotic Skill Development in a Resident Robotic Hernia Curriculum: A Retrospective Cohort Study

Background

Hernia repairs are one of the most common general surgery procedures and an essential part of training for general surgery residents. The widespread incorporation of robotic hernia repairs warrants the development of a procedure-specific robotic curriculum to assist novice surgeons in improving technical skills.

Objective

To evaluate a robotic hernia simulation-based curriculum for general surgery residents using video review.

Methods

Retrospective cohort study of PGY-3 general surgery residents from the University of Chicago from 2019 to 2021. The residents completed inguinal hernia repair (IHR) and ventral hernia repair (VHR) drills as part of a robotic simulation curriculum. The drills were recorded and graded according to the modified objective structured assessment of technical skills (OSATS) and time to completion. The drills were completed by 3 attending surgeons to establish gold-standard benchmarks.

Results

In total, 20 residents started the curriculum, 19 completed all IHR drills and 17 completed all VHR drills. Attending surgeon total OSATS scores and time to completion were significantly better than the trainees on the first attempt (P < 0.05). When comparing 1st to 4th attempt, resident OSATS scores improved significantly for IHR (15.5 vs 23.3; P < 0.001) and VHR (16.8 vs 23.3; P < 0.001). Time also improved over 4 attempts (IHR: 28.5 vs 20.5 minutes; P < 0.001 and VHR: 29.6 vs 21.2 minutes; P < 0.001). Residents achieved attending-level OSATS scores by their fourth attempt for VHR, but not for IHR. Residents did not achieve attending-level times for either hernia drills.

Conclusions

The robotic hernia curriculum improved resident performance on hernia repair drills and was well-received by the residents.

Effects of Mentorship on Surgery Residents' Burnout and Well-Being: A Scoping Review

BACKGROUND

In surgical training, a mentor is a more senior and experienced surgeon who guides a surgical trainee to meet personal, professional, and educational goals. Although mentorship is widely assumed to positively affect surgical residents' professional development, a more nuanced understanding of mentorship's impact is lacking and urgently needed as burnout rates among residents increase. This study aims to summarize the current literature on the effects of mentorship on surgical residents' burnout and well-being.

METHODS

A comprehensive literature review was performed with key terms related to "surgical resident" and "mentor" using Pubmed, Embase, and ProQuest databases for primary studies published in the United States or Canada from January 1, 2010 to December 9, 2022 that measured outcomes related to burnout and well-being. Multiple reviewers screened titles and abstracts for relevance, then full-text articles for eligibility.

RESULTS

Initial search resulted in 1,468 unique articles, and 19 articles were included after review. Only one article was a randomized controlled trial. Twelve studies described a decrease in burnout rates or in outcomes related to burnout. In contrast, 4 studies identified negative outcomes related to burnout. Six studies showed improved well-being or related outcomes. One study was not able to show a change in self-valuation between coached and noncoached residents.

CONCLUSION

High quality mentorship can be associated with improved well-being and decreased burnout in surgical residents, but the key elements of effective and helpful mentorship remain poorly characterized. This summary highlights the importance of making mentorship accessible to surgical residents, and training faculty to be effective mentors.

The Grade C Pancreatic Fistula

Grade C pancreatic fistulas are associated with severe morbidity and a significant risk of mortality. High-risk pancreatic anastomoses can be predicted to allow best practice fistula mitigation techniques. In these high-risk glands, any deviation from a stable postoperative clinical course should prompt early computed tomography and aggressive, percutaneous drainage of the operative bed. If salvage surgery is necessary, drainage of the operative bed and/or external diversion of pancreatic juice via stenting while completion pancreatectomy should be avoided. Senior mentorship in the perioperative period offers an opportunity to decrease this complication even in early career surgeons.

Effect of surgical approach on early return to intended oncologic therapy after resection for pancreatic ductal adenocarcinoma

BACKGROUND

Although robotic pancreatectomy may facilitate an earlier functional recovery, the impact of a robotic pancreatectomy program during its early experience on the timing of return to intended oncologic therapy (RIOT) after surgery is unknown.

METHODS

In this retrospective cohort study, we used propensity score matching with a 1:2 ratio to compare patients who underwent robotic or open surgery (distal pancreatectomy or pancreatoduodenectomy) for pancreatic ductal adenocarcinoma (PDAC) during the first 3 years of our robotic pancreatectomy experience (January 2018-December 2021). Generalized estimating equations modeling was used to evaluate the effect of surgical approach on early RIOT, defined as adjuvant chemotherapy initiation within 8 weeks after surgery, and late RIOT, defined as initiation within 12 weeks after surgery.

RESULTS

The matched cohort included 26 patients who underwent robotic pancreatectomy and 52 patients who underwent open pancreatectomy. Rates of receipt of adjuvant chemotherapy were 96.2% and 78.9%, respectively. Rate of early RIOT in the robotic group (73.1% was higher than that in the open group (44.2%; P = 0.018). In multivariable analysis, a robotic approach was associated with early RIOT (odds ratio, 3.54; 95% confidence interval 1.08-11.62; P = 0.038). Surgical approach did not impact late RIOT (odds ratio, 3.21; 95% confidence interval 0.71-14.38; P = 0.128).

CONCLUSIONS

Compared with open pancreatectomy, robotic pancreatectomy did not delay RIOT. In fact, odds of early RIOT were increased, which supports the oncological safety of our robotic pancreatectomy program during its implementation.

Safety of robotic cholecystectomy as index training procedure: the UK experience

AIMS

To evaluate the safety profile of robotic cholecystectomy performed within the United Kingdom (UK) Robotic Hepatopancreatobiliary (HPB) training programme.

METHODS

A retrospective evaluation of prospectively collected data from eleven centres participating in the UK Robotic HPB training programme was conducted. All adult patients undergoing robotic cholecystectomy for symptomatic gallstone disease or gallbladder polyp were considered. Bile duct injury, conversion to open procedure, conversion to subtotal cholecystectomy, length of hospital stay, 30-day re-admission, and post-operative complications were the evaluated outcome parameters.

RESULTS

A total of 600 patients were included. The median age was 53 (IQR 65-41) years and the majority (72.7%; 436/600) were female. The main indications for robotic cholecystectomy were biliary colic (55.5%, 333/600), cholecystitis (18.8%, 113/600), gallbladder polyps (7.7%, 46/600), and pancreatitis (6.2%, 37/600). The median length of stay was 0 (IQR 0-1) days. Of the included patients, 88.5% (531/600) were discharged on the day of procedure with 30-day re-admission rate of 5.5% (33/600). There were no bile duct injuries and the rate of conversion to open was 0.8% (5/600) with subtotal cholecystectomy rate of 0.8% (5/600).

CONCLUSION

The current study confirms that robotic cholecystectomy can be safely implemented to routine practice with a low risk of bile duct injury, low bile leak rate, low conversion to open surgery, and low need for subtotal cholecystectomy.

Task division by multiple console surgeons is beneficial for safe robotic pancreaticoduodenectomy implementation and education

BACKGROUND

The optimal approach for the safe implementation and education of robotic pancreaticoduodenectomy (RPD) remains unclear. Prolonged operation time may cause surgeon fatigue and result in perioperative complications. To solve this issue, our department adopted task division by the console surgeon turnover between resection and reconstruction in 2022.

METHODS

This study retrospectively investigated consecutive patients who underwent RPD from November 2009 (initial introduction of RPD) to December 2023. The analysis excluded patients who underwent concomitant resection of other organs. The cases performed by a single console surgeon (single approach) were compared with those performed by two or more console surgeons (multiple approach).

RESULTS

This study analyzed 85 consecutive RPD cases, including 51 with the single approach and 34 with the multiple approach. The operation time was significantly shorter (832 vs. 618 min, p < 0.001), and the postoperative major complication was less frequent (45% vs. 12%, p = 0.003) in the multiple approach group, although less experienced surgeons performed the multiple approach (number of RPD experiences: 19 cases vs. 5 cases, p < 0.001). The console surgeon turnover between the resection and reconstruction resulted in a safe pancreatojejunostomy performed by the less experienced surgeon (number of pancreatic reconstruction experiences: 6.5 vs. 14 cases, p = 0.010). Surgeons who started RPD with a multiple approach observed a reduction in surgical time and a lower incidence of complications earlier than those who started with a single approach.

CONCLUSION

Task division during the early introduction phase of RPD using the multiple approach demonstrated potential contributions to improved surgical outcomes and enhanced educational benefits.

Implementing a robotic hepatopancreatobiliary program for new faculty: safety, feasibility and lessons learned

Robotic surgery is increasingly utilized in hepatopancreatobiliary (HPB) surgery, but the learning curve is a substantial obstacle hindering implementation. Comprehensive robotic training can help to surmount this obstacle; however, despite the expansion of robotic training into residency and fellowship programs, limited data are available about how this translates into successful incorporation in faculty practice. All operations performed during the first three years of practice of a surgical oncologist at a tertiary care academic institution were retrospectively reviewed. The surgeon underwent comprehensive robotic training during residency and fellowship. 137 HPB operations were performed during the initial three years of practice. Over 80% were performed robotically each year across a spectrum of HPB procedures with a 6% conversion rate. Median operative time, a metric for operative proficiency and evaluation for a learning curve, was similar throughout the study period for each major operation and below several reported optimized operative time benchmarks. The major complications, defined as a Clavien-Dindo of 3 or more, were similar across the experience and comparable to published series. Comprehensive robotic training in residency and fellowship as well as a dedicated, well-trained operative team allows for early attainment of optimized outcomes in a new HPB robotic practice.

Results

137 HPB operations were performed during the initial three years of practice. Over 80% were performed robotically each year across a spectrum of HPB procedures with a 6% conversion rate. Median operative time, the optimal metric for operative proficiency and evaluation for a learning curve, was similar throughout the study period for each major operation and below several reported optimized operative times. Major complications were similar across the experience and comparable to published series.

Conclusion

Segmental Duodenal Resections: Toward Defining Indications, Complexity, and Coding

BACKGROUND

Segmental resections of the duodenum are uncommonly performed and are technically challenging due to intimate relationships with the biliary tree, pancreas, and superior mesenteric vessels. The objective of this study was to assess indications, operative strategy, and outcomes of duodenal resections and to advocate that this form of resection deserves its own unique Current Procedural Terminology (CPT) and Relative Value Unit (RVU) structure.

METHODS

Patients undergoing isolated and partial duodenal resection from 2008-2023 at University of Tennessee Health Science Center affiliated hospitals were retrospectively reviewed. Factors examined included clinical presentation, diagnostic evaluation, operative time, and technique, 90-day morbidity and mortality, and pathologic and survival outcomes.

RESULTS

Thirty-one patients were identified with majority female and a median age of 61. Diagnostic studies included computed tomography and upper (including push) endoscopy. Reconstruction most often involved side-to-side duodenojejunostomy following distal duodenal resection. Intraoperative evaluation (IOE) of the biliary tree was utilized to assess and protect pancreaticobiliary structures in eleven patients. Median operative time was 206 min, increasing to 236 min when IOE was necessary. Procedure-related morbidity was 23% with one 90-day mortality. Median postoperative length of stay was 9 days. Pathology included benign adenoma, adenocarcinoma, GIST, neuroendocrine neoplasms, and erosive metastatic deposit.

CONCLUSION

Duodenal resections can be effectively employed to safely address diverse pathologies. These procedures are characterized by long operative times, extended hospital stays, and an incidence of postoperative complications that mimics that of pancreatic resection. This work highlights the need for modification to the CPT system to accurately define these distinct procedures for future research endeavors and development of a more accurate valuation unit.

Residents perform better technically, have less stress and workload, and prefer robotic to laparoscopic technique during inanimate simulation

INTRODUCTION

With the widespread adoption of minimally invasive surgery, there is a growing need for surgical residents to be trained by a procedure-specific curriculum. This study aimed to evaluate the technical performance and feedback of surgical residents undergoing the robotic and laparoscopic hepaticojejunostomy (HJ) and gastrojejunostomy (GJ) biotissue modules.

METHODS

A total of 23 PGY-3 surgical residents participated in this study and performed the laparoscopic and robotic HJ and GJ drills, which were recorded and scored by two independent graders using the modified objective structured assessment of technical skills (OSATS). After completing each drill, all participants filled out the NASA Task Load Index (NASA-TLX), Borg Exertion Scale, and Edwards Arousal Rating Questionnaire.

RESULTS

Twenty-two (95.7%) residents had already received fundamentals of laparoscopic surgery certification. Eighteen (78.3%) residents had robotic virtual simulation training and the median (range) number of robotic surgery console experience was 4 (0-30). In the HJ comparison of the six OSATS domains, the robotic system was superior in Gentleness (p = 0.031). In the GJ comparison, the robotic system was superior in Time and Motion (p < 0.001), Instrument Handling (p = 0.001), Flow of Operation (p = 0.002), Tissue Exposure (p = 0.013), and Summary (p < 0.001). Participants answered significantly higher demand scores for laparoscopy on all six facets of NASA-TLX for both HJ and GJ (p < 0.05). The Borg Level of Exertion was > 2 points higher for laparoscopic HJ and GJ (p < 0.001). Residents rated more Nervousness and Anxiety for laparoscopic compared to robotic (p < 0.05) HJ and GJ. Additionally, when asked to score preference for robotic and laparoscopic approach in terms of technique and ergonomics, residents scored robot as better (laparoscopy worse) for both HJ and GJ in both domains.

CONCLUSIONS

The robotic surgical system provided a more favorable environment for trainees with less mental and physical burden for minimally invasive HJ and GJ curriculum.

Impact of educational video on performance in robotic simulation training (TAKUMI-1): a randomized controlled trial

The use of virtual reality for simulations plays an important role in the initial training for robotic surgery. This randomized controlled trial aimed to investigate the impact of educational video on the performance of robotic simulation. Participants were randomized into the intervention (video) group that received an educational video and robotic simulation training or the control group that received only simulation training. The da Vinci® Skills Simulator was used for the basic course, including nine drills. The primary endpoint was the overall score of nine drills in cycles 1-10. Secondary endpoints included overall, efficiency, and penalty scores in each cycle, as well as the learning curves evaluated by the cumulative sum (CUSUM) analysis. Between September 2021 and May 2022, 20 participants were assigned to the video (n = 10) and control (n = 10) groups. The video group had significantly higher overall scores than the control group (90.8 vs. 72.4, P < 0.001). Significantly higher overall scores and lower penalty scores were confirmed, mainly in cycles 1-5. CUSUM analysis revealed a shorter learning curve in the video group. The present study demonstrated that educational video training can be effective in improving the performance of robotic simulation training and shortening the learning curve.

Distal Pancreatectomy Fistula Risk Score (D-FRS): Development and International Validation

OBJECTIVE

To develop 2 distinct preoperative and intraoperative risk scores to predict postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP) to improve preventive and mitigation strategies, respectively.

BACKGROUND

POPF remains the most common complication after DP. Despite several known risk factors, an adequate risk model has not been developed yet.

METHODS

Two prediction risk scores were designed using data of patients undergoing DP in 2 Italian centers (2014-2016) utilizing multivariable logistic regression. The preoperative score (calculated before surgery) aims to facilitate preventive strategies and the intraoperative score (calculated at the end of surgery) aims to facilitate mitigation strategies. Internal validation was achieved using bootstrapping. These data were pooled with data from 5 centers from the United States and the Netherlands (2007-2016) to assess discrimination and calibration in an internal-external validation procedure.

RESULTS

Overall, 1336 patients after DP were included, of whom 291 (22%) developed POPF. The preoperative distal fistula risk score (preoperative D-FRS) included 2 variables: pancreatic neck thickness [odds ratio: 1.14; 95% confidence interval (CI): 1.11-1.17 per mm increase] and pancreatic duct diameter (OR: 1.46; 95% CI: 1.32-1.65 per mm increase). The model performed well with an area under the receiver operating characteristic curve of 0.83 (95% CI: 0.78-0.88) and 0.73 (95% CI: 0.70-0.76) upon internal-external validation. Three risk groups were identified: low risk (<10%), intermediate risk (10%-25%), and high risk (>25%) for POPF with 238 (18%), 684 (51%), and 414 (31%) patients, respectively. The intraoperative risk score (intraoperative D-FRS) added body mass index, pancreatic texture, and operative time as variables with an area under the receiver operating characteristic curve of 0.80 (95% CI: 0.74-0.85).

CONCLUSIONS

The preoperative and the intraoperative D-FRS are the first validated risk scores for POPF after DP and are readily available at: http://www.pancreascalculator.com . The 3 distinct risk groups allow for personalized treatment and benchmarking.

Identifying the preoperative factors predicting the surgical difficulty of robotic distal pancreatectomy

BACKGROUND

Few studies have evaluated the preoperative factors predicting the surgical difficulty of robotic distal pancreatectomy (RDP). This study aims to explore such factors and provide guidance on the selection of suitable patients to aid surgeons lacking extensive experience in RDP.

METHODS

A retrospective study was conducted on consecutive patients who underwent RDP to identify preoperative factors predicting surgical difficulty. High surgical difficulty was defined by both operation time and intraoperative estimated blood loss exceeding their median, or by conversion to laparotomy.

RESULTS

A total of 161 patients were ultimately enrolled, including 51 patients with high levels of surgical difficulty. Multivariate analysis revealed that male sex [OR (95% CI): 4.07 (1.77,9.40), p = 0.001], body mass index (BMI) ≥ 25 kg/m² OR (95% CI): 2.27 (1.03,5.00), p = 0.042], tumors located at the neck of the pancreas [OR (95% CI): 4.15 (1.49,11.56), p = 0.006] and splenic artery type B [OR (95% CI): 3.28 (1.09,9.91), p = 0.035] were independent risk factors for surgical difficulty. Regarding postoperative complications, high surgical difficulty was associated with the risk of overall complications and pancreatic fistula (grade B/C) (49.0% vs. 22.7%, p < 0.001; 39.2% vs. 19.1%, p = 0.006).

CONCLUSION

Male sex, body mass index ≥ 25 kg/m2, tumor located at the neck of the pancreas and splenic artery type B are associated with a high RDP difficulty level. These factors can be used preoperatively to assess the difficulty level of surgery, to help surgeons choose patients suitable for them and ensure surgical safety.

Transition from open to robotic distal pancreatectomy in a low volume pancreatic surgery country: a single Australian centre experience

BACKGROUND

Advances in technology and techniques have allowed for robotic distal pancreatectomies to be readily performed in patients at high volume centres. This study describes the experience of a single surgeon during the learning curve and transition from open to robotic distal pancreatectomy in Australia, a traditionally low volume pancreatic surgery country.

METHODS

All patients undergoing distal pancreatectomy at an Australian-based tertiary referral centre between 2010 and 2021 were reviewed retrospectively. Demographic, clinicopathologic and survival data were analysed to compare perioperative and oncological outcomes between patients who underwent open, laparoscopic and robotic distal pancreatectomies.

RESULTS

A total of 178 distal pancreatectomies were identified for analysis during the study period. Ninety-one open distal pancreatectomies (ODP), 48 laparoscopic distal pancreatectomies (LDP), and 39 robotic distal pancreatectomies (RDP) were performed. Robotic distal pancreatectomy was non-inferior with respect to perioperative outcomes and yielded statistically non-significant advantages over LDP and ODP.

CONCLUSION

RDP is feasible and can be performed safely in well-selected patients during the learning phase at large pancreatic centres in a traditionally low-volume country like Australia. Referral to large pancreatic centres where access to the robotic platform and surgeon experience is not a barrier, and where a robust multidisciplinary team meeting can take place, remains pivotal in the introduction and transition toward the robotic approach for management of patients with pancreatic body or tail lesions.

A systematic review of robotic surgery curricula using a contemporary educational framework

BACKGROUND

There has been a rising trend in robotic surgery. Thus, there is demand for a robotic surgery curriculum (RSC) for training surgical trainees and practicing surgeons. There are limited data available about current curricular designs and the extent to which they have incorporated educational frameworks. Our aim was to study the existing robotic surgery curricula using Kern's 6-step approach in curriculum development.

METHODS

A systematic review was conducted using PubMed, PubMed Central, Cochrane, Embase, and Scopus (we searched studies from 2001 to 2021). PRISMA Guidelines was used to guide the search. Curriculum designed for general surgery and its subspecialties were included. Urology and gynecology were excluded. The articles were reviewed by five reviewers.

RESULTS

Our review yielded 71 articles, including 39 curricula at 9 different settings. Using Kern's framework, we demonstrated that the majority of robotic surgery curricula contained all the elements of Kern's curricular design. However, there were significant deficiencies in important aspects of these curricula i.e., implementation, the quality of assessment tools for measurement of performance and evaluation of the educational value of these interventions. Most institutions used commercial virtual reality simulators (VRS) as the main component of their RSC and 23% of curricula only used VRS.

CONCLUSIONS

Although majority of these studies contained all the elements of Kern's framework, there are critical deficiencies in the components of existing curricula. Future curricula should be designed using established educational frameworks to improve the quality of robotic surgery training.

The learning curve for robot-assisted distal pancreatectomy: a single-center experience of 301 cases

Robotic distal pancreatectomy (RDP) has become a routine procedure in many pancreatic centers. This study aimed to describe a single-center experience with RDP since the first case, identify the learning curves of operation time and complication rate, and discuss the safety and feasibility of RDP.

Methods

We collected and retrospectively analyzed the single-center surgical experience of 301 patients undergoing RDP at Peking Union Medical College Hospital (PUMCH) between 2012 and 2022 and described the change in operation proficiency and occurrence of perioperative complications in this observational study. The learning curve was assessed using the cumulative sum method.

Results

We observed a three-phase pattern of RDP learning with operation time, complications, and postoperative pancreatic fistula as indicators and a two-phase pattern for spleening-preserving success. The mean operation time was 3.9 hours. The incidence rate of clinically significant postoperative pancreatic fistula (CRPOPF) was 17.9% and overall Clavien-Dindo complication rate (≥3) was 16.6%. The change of postoperative complicate rate was correlated with percentage of malignant cases.

Conclusion

In the last decade, an evident decrease was seen in operation time, complication rate, and an increase in the spleen-preserving rate of distal pancreatectomy. With proper training, RDP is a safe and feasible procedure.

Is robotic distal pancreatectomy better than laparoscopic distal pancreatectomy after the learning curve? A systematic review and meta-analysis

Aim

The aim of this study was to compare the safety and overall effect of robotic distal pancreatectomy (RDP) to laparoscopic distal pancreatectomy (LDP) after the learning curve, especially in perioperative outcome and short-term oncological outcome.

Methods

A literature search was performed by two authors independently using PubMed, Embase, and Web of Science to identify any studies comparing the results of RDP versus LDP published until 5 January 2022. Only the studies where RDP was performed in more than 35 cases were included in this study. We performed a meta-analysis of operative time, blood loss, reoperation, readmission, hospital stay, overall complications, major complications, postoperative pancreatic fistula (POPF), blood transfusion, conversion to open surgery, spleen preservation, tumor size, R0 resection, and lymph node dissection.

Results

Our search identified 15 eligible studies, totaling 4,062 patients (1,413 RDP). It seems that the RDP group had a higher rate of smaller tumor size than the LDP group (MD: −0.15; 95% CI: −0.20 to −0.09; p &lt; 0.00001). Furthermore, compared with LPD, RDP was associated with a higher spleen preservation rate (OR: 2.19; 95% CI: 1.36–3.54; p = 0.001) and lower rate of conversion to open surgery (OR: 0.43; 95% CI: 0.33–0.55; p &lt; 0.00001). Our study revealed that there were no significant differences in operative time, overall complications, major complications, blood loss, blood transfusion, reoperation, readmission, POPF, and lymph node dissection between RDP and LDP.

Conclusions

RDP is safe and feasible for distal pancreatectomy compared with LDP, and it can reduce the rate of conversion to open surgery and increase the rate of spleen preservation, which needs to be further confirmed by quality comparative studies with large samples.

Robotische Pankreaschirurgie – Lernkurve und Etablierung

Minimalinvasive Resektionstechniken zur Behandlung verschiedener Pathologien des Pankreas sind potenziell vorteilhaft für die behandelten Patienten in Bezug auf Rekonvaleszenzzeit und postoperative Morbidität, stellen jedoch eine besondere technische Herausforderung für den behandelnden Chirurgen dar. Der Einzug der robotischen Technik in die Viszeralchirurgie bietet eine prinzipielle Möglichkeit zur weitreichenden Verbreitung minimalinvasiver Verfahren in der Pankreaschirurgie.

Ziel dieser Arbeit war es, die Entwicklungsmöglichkeiten der robotischen Pankreaschirurgie in Deutschland zu überprüfen. Datengrundlage sind die Qualitätsberichte der Krankenhäuser der Jahre 2015–2019 kombiniert mit einer selektiven Literaturrecherche.

Die Anzahl der vorliegenden Qualitätsberichte reduzierte sich von 2015 bis 2019 von 1635 auf 1594. Im Median führten 96 Kliniken 11–20, 56 Kliniken 21–50 und 15 Kliniken mehr als 50 Pankreaskopfresektionen jährlich durch. Bei den Linksresektionen waren es 35 Kliniken mit 11–20, 14 Kliniken mit 21–50 und 2 Kliniken mit mehr als 50 Eingriffen. Unter Berücksichtigung aller Kliniken, die 5 oder mehr Linksresektionen pro Jahr durchführen, wurden an nur 29 Kliniken minimalinvasive Verfahren eingesetzt. Der Anteil an laparoskopischen Linksresektionen über 50% wurde an nur 7 Kliniken beschrieben.

Nach Datenlage in der Literatur divergieren die Lernkurven für die robotische Pankreaslinks- und Pankreaskopfresektion. Während die Lernkurve für die robotische Pankreaslinksresektion nach etwa 20 Eingriffen durchlaufen ist, hat die Lernkurve für die robotische Pankreaskopfresektion mehrere Plateaus, die etwa nach 30, 100 und 250 Eingriffen erreicht werden.

Aufgrund der dezentralen Struktur der Pankreaschirurgie in Deutschland scheint ein flächendeckendes Angebot robotischer Verfahren aktuell in weiter Ferne. Insbesondere die Etablierung der robotischen Pankreaskopfresektion wird zunächst Zentren mit entsprechend hoher Fallzahl vorbehalten bleiben.
