Presence of a fellowship improves perioperative outcomes following hepatopancreatobiliary procedures

Separating the components of an abdominal wall fellowship

Complex abdominal wall reconstruction is an emerging subspecialty yet, despite the abundance of abdominal wall hernias requiring treatment and the increasing complexity of this type of surgery, there are few opportunities for surgeons to gain subspecialist training in this field. In this paper we discuss the need for focused training in complex abdominal wall reconstruction, outline some of the problems that may be hindering the availability of such opportunities and propose potential solutions to these issues.

Comparison of the prognosis of BCLC stage A ruptured hepatocellular carcinoma patients after undergoing transarterial chemoembolization (TACE) or hepatectomy: a propensity score-matched landmark analysis

BACKGROUND

At present, the choice of treatment modalities for ruptured hepatocellular carcinoma patients in BCLC stage A remains controversial, and this study compared the overall survival of ruptured HCC patients undergoing TACE or hepatectomy.

METHODS

A total of 283 ruptured HCC patients treated at our liver surgery center were included in our study, of which 175 were treated with hepatectomy and 108 were treated with TACE. To reduce selection bias, we used a propensity score matching (PSM) model, which yielded a total of 88 pairs of patients. We used the Kaplan-Meier method to compare the long-term prognosis, and the Landmark method was used to compare the short-term and long-term prognoses of patients after PSM. Finally, we performed subgroup analysis according to whether it met the Milan criteria.

RESULTS

After PSM, in the hepatectomy group, the 1-, 3-, and 5 year OS rates were 73.4%, 45.4%, and 33.9%, respectively. In the TACE group, the 1-, 3-, and 5 year OS rates were 58.5%, 40.6%, and 23.2%, respectively. Within one year, the hepatectomy group had a better prognosis than the TACE group (P = 0.022), but there was no difference in long-term survival(P = 0.936). In the subgroup analysis, in patients who met the Milan criteria, the survival curve indicated that there was no statistically significant difference in the survival prognosis between the two groups (P = 0.294) HR = 1.56(0.68-3.59); in the patients beyond the Milan criteria, the survival time was 28.0 months (20.0-34.0) in patients who underwent hepatectomy and 18 months (9.8-26.2) in patients who underwent TACE, and the survival curve indicated a statistically significant difference (P = 0.043) HR = 1.57(1.01-2.43).

CONCLUSION

Our propensity score-matched study found that ruptured HCC patients treated by hepatectomy had a better short-term prognosis than those treated by TACE, but there was no difference in the long-term prognosis between the two treatment groups.

The essential requirements for an HPB centre to deliver high-quality outcomes

The concept of a centre approach to the treatment of patients with complex disorders, such as those with hepato-pancreato-biliary (HPB) diseases, is widely applied, although what is needed for an HPB centre to achieve high-quality outcomes remains unclear. We therefore conducted a literature review, which highlighted the paucity of information linking centre structure or process to outcome data outside of caseloads, specialisation, and quality of training. We then conducted an international survey among the largest 107 HPB centres with experts in HPB surgery and found that most responders work in 'virtual' HPB centres without dedicated space, assigned beds, nor personal. We finally analysed our experience with the Swiss HPB centre, previously reported in this journal 15 years ago, disclosing that budget priorities set by the hospital administration may prevent the development of a fully integrated centre, for example through inconsistent assignment of the centre's beds to HBP patients or removal of dedicated intermediate care beds. We propose criteria for essential requirements for an HPB centre to deliver high-quality outcomes, with the concept of "centre of reference" limited to actual, as opposed to virtual, centres.

Quality Assurance for Point-of-Care Ultrasound in North American Pediatric Emergency Medicine Fellowships

OBJECTIVES

The American Academy of Pediatrics, the Society for Academic Emergency Medicine, and the American College of Emergency Physicians released a policy statement endorsing the use of point-of-care ultrasound (POCUS) by pediatric emergency medicine (PEM) providers. This statement specifically recommends that emergency departments have a credentialing and quality assurance (QA) program for POCUS. There is limited knowledge of how QA for POCUS is currently carried out in pediatric emergency departments with PEM training programs.

METHODS

We sent a cross-sectional web-based survey to all 81 PEM fellowship-training programs in the United States and Canada between June 2016 and June 2017.

RESULTS

Sixty-six of 81 programs (81.2%) responded. Sixty-five percent of responding PEM training programs had POCUS-trained faculty or a POCUS champion at their institution. Forty-six percent had a POCUS fellowship in their institution, with 10 programs having PEM-specific POCUS fellowships. Programs with POCUS fellowships were more likely to save all images, review all scans, review scans more frequently, provide feedback, and bill compared with programs without POCUS fellowships.

CONCLUSIONS

Point-of-care ultrasound is growing in PEM fellowship-training programs, with a majority of programs now having faculty members trained or interested specifically in POCUS. Most programs prefer more frequent and thorough QA processes, and programs with POCUS fellowships are more likely to have more frequent and thorough QA processes.

Complications and Readmissions Associated with First Assistant Training Level Following Elective Bariatric Surgery

BACKGROUND

Little is known regarding the variation in training level and potential clinical impact of the first assistant in bariatric surgery. We describe the postoperative 30-day complications and readmissions following elective bariatric procedures by training level of the first assistant.

METHODS

The ACS-MBSAQIP database was queried to identify patients who underwent elective sleeve gastrectomy, Roux-En-Y gastric bypass, duodenal switch, band placement, and revision from 2015 to 2016. Patients were divided into cohorts based on training level of the first assistant (attending, fellow, resident, physician assistant/nurse practitioner, none). Outcomes included 30-day death or serious morbidity (DSM) and readmission. Multivariable logistic regression models, adjusting for patient and procedure characteristics, were estimated to examine differences in outcomes by first assistant training level.

RESULTS

Of 410,535 procedures performed between 2015 and 2016, the training level of the first assistant included 21.3% attending, 8.7% fellow, 16.5% resident, 37.6% PA/NP, and 15.9% none. Operative time was significantly longer in the fellow and resident first assistant cohorts when compared with all other cohorts. Overall rates of 30-day DSM were low, ranging from 3.2 to 3.8%, while 30-day readmission rates ranged from 5.1 to 5.9%. Following adjustment for patient characteristics and type of procedure, first assistant training level had no significant impact on DSM or readmission.

CONCLUSIONS

Variation in training level of the first assist during bariatric surgery had no influence on DSM or readmissions. This provides reassurance that the inclusion of a wide range of first assistants in bariatric procedures does not negatively impact patient outcomes.

Unifying the Hepatopancreatobiliary Surgery Fellowship Curriculum via Delphi Consensus

BACKGROUND

Hepatopancreatobiliary (HPB) Fellowship training in the Americas consists of 3 distinctive routes with variable curricula: Surgical Oncology Fellowship via the Society of Surgical Oncology (SSO), Abdominal Transplant Surgery Fellowship via the American Society of Transplant Surgeons (ASTS), and HPB Fellowship via the Americas Hepato-Pancreato-Biliary Association (AHPBA). Our objective was to establish a pan-American consensus among HPB surgeons, surgical oncologists, abdominal transplant surgeons, and general surgery residency program directors (GSPDs) on a core knowledge curriculum for HPB fellowship, and to identify topics appropriate for general surgery residency and subspecialty beyond HPB fellowship.

STUDY DESIGN

A 3-round modified Delphi process was used. Baseline statements were developed by the Education and Training Committee of the AHPBA, in collaboration with representatives of the SSO, ASTS, and GSPDs. The expert panel, consisting of members of the 3 societies together with GSPDs, rated the statements on a 5-point Likert scale and suggested editing or adding new statements. A statement was included in the final curriculum when Cronbach's alpha value was ≥ 0.8 and ≥ 80% of the panel agreed on inclusion.

RESULTS

The response rate was 100% for the first round, and 98% for the second and third rounds. Eighty-nine of 138 proposed statements were included in the final HPB fellowship curriculum. Curricula for general surgery residency and subspecialty beyond HPB fellowship included 50 and 29 statements, respectively.

CONCLUSIONS

A multinational consensus on core knowledge for an HPB fellowship curriculum was achieved via the modified Delphi method. This core curriculum may be used to standardize HPB fellowship training across different pathways in the Americas.

The Impact of Establishing a Dedicated Liver Surgery Program at a University-affiliated Hospital on Workforce, Workload, Surgical Outcomes, and Trainee Surgical Autonomy and Academic Output

Objective

To detail the implementation of a dedicated liver surgery program at a university-affiliated hospital and to analyze its impact on the community, workforce, workload, complexity of cases, the short-term outcomes, and residents and young faculties progression toward technical autonomy and academic production.

Background

Due to the increased burden of liver tumors worldwide, there is an increased need for liver centers to better serve the community and facilitate the education of trainees in this field.

Methods

The implementation of the program is described. The 3 domains of workload, research, and teaching were compared between 2-year periods before and after the implementation of the new program. The severity of disease, complexity of procedures, and subsequent morbidity and mortality were compared.

Results

Compared with the 2-year period before the implementation of the new program, the number of liver resections increased by 36% within 2 years. The number of highly complex resections, the number of liver resections performed by residents and young faculties, and the number of publications increased 5.5-, 40-, and 6-fold, respectively. This was achieved by operating on more severe patients and performing more complex procedures, at the cost of a significant increase in morbidity but not mortality. Nevertheless, operations during the second period did not emerge as an independent predictor of severe morbidity.

Conclusions

A new liver surgery program can fill the gap between the demand for and supply of liver surgeries, benefiting the community and the development of the next generation of liver surgeons.

Finding the Balance: General Surgery Resident Versus Fellow Training and Exposure in Hepatobiliary and Pancreatic Surgery

BACKGROUND

Institutions training both General Surgery (GS) residents and Hepato-Pancreatico-Biliary (HPB) fellows must strive for adequate case volumes for each trainee cohort.

METHODS

Six academic years of graduating ACGME Residency and HPB Fellowship Council case logs (July 2011-June 2017) and institutional administrative faculty billing data were examined at a single high-volume center with a formal HPB Surgical Division with both GS Residency and HPB Surgery Fellowship trainees.

RESULTS

During the 6-year period, 7482 operations were performed by HPB faculty (5.5 total full-time equivalent (FTE)) and included 2419 major liver, 375 major biliary, and 1591 major pancreas cases. Residents/fellows performed 1102 (50%)/1101 (50%) of all major liver operations, 165 (49.7%)/163 (50.3%) major biliary operations, and 843 (59.2%)/581 (40.8%) major pancreas operations, with significantly different case mix of pancreas for resident versus fellow, p < 0.0001. The overall relative proportion of total HPB cases performed by residents versus fellows was 53%/47%, respectively, and this was stable over time, with no significant decrease in resident exposure/cases with dedicated HPB fellowship.

CONCLUSIONS

Our experience in training both GS residents and HPB fellows with a formal HPB Surgical Division suggests that a high volume HPB Division allows for more than adequate exposure for both groups of trainees.

Quality performance indicators for hepato-pancreatico-biliary procedures: a systematic review

BACKGROUND

This systematic review was undertaken to define and summarize existing, proposed quality performance indicators (QPI) for hepato-pancreatico-biliary (HPB) procedures.

METHODS

A systematic literature review identified studies reporting on quality indicators for cholecystectomy, hepatectomy, pancreatectomy and complex biliary surgical procedures. The databases searched were MEDLINE, EMBASE, PubMed, and SCOPUS, with all literature available until the search date of 1 May 2020 included. The reference lists of all included papers, as well as related review articles, were manually searched to identify further relevant studies.

RESULTS

Forty-five publications report quality indicators for pancreatectomy (n = 22), hepatectomy (n = 7), HPB resections in general (n = 12), and cholecystectomy (n = 6). No publications proposed QPI for complex biliary surgery. The 45 papers used national audit (n = 18), consensus methodology (n = 5), state-wide audit (n = 3), unit audit (n = 9), review methodology (n = 9), and survey methodology (n = 1). Sixty-one QPI were reported for pancreatectomy, 22 reported for hepatectomy, and 14 reported for HPB resections in general, in domains of infrastructure, provider, and documentation. Fourteen infrastructure and provider-based QPI were reported for cholecystectomy.

CONCLUSIONS

There are few internationally agreed QPI for HPB procedures that allow global comparison of provider performance and that set aspirational goals for patient care and experience.

Choices of Therapeutic Strategies for Colorectal Liver Metastases Among Expert Liver Surgeons: A Throw of the Dice?

OBJECTIVE

To test the degree of agreement in selecting therapeutic options for patients suffering from colorectal liver metastasis (CRLM) among surgical experts around the globe.

SUMMARY/BACKGROUND

Only few areas in medicine have seen so many novel therapeutic options over the past decades as for liver tumors. Significant variations may therefore exist regarding the choices of treatment, even among experts, which may confuse both the medical community and patients.

METHODS

Ten cases of CRLM with different levels of complexity were presented to 43 expert liver surgeons from 23 countries and 4 continents. Experts were defined as experienced surgeons with academic contributions to the field of liver tumors. Experts provided information on their medical education and current practice in liver surgery and transplantation. Using an online platform, they chose their strategy in treating each case from defined multiple choices with added comments. Inter-rater agreement among experts and cases was calculated using free-marginal multirater kappa methodology. A similar, but adjusted survey was presented to 60 general surgeons from Asia, Europe, and North America to test their attitude in treating or referring complex patients to expert centers.

RESULTS

Thirty-eight (88%) experts completed the evaluation. Most of them are in leading positions (92%) with a median clinical experience of 25 years. Agreement on therapeutic strategies among them was none to minimal in more than half of the cases with kappa varying from 0.00 to 0.39. Many general surgeons may not refer the complex cases to expert centers, including in Europe, where they also engage in complex liver surgeries.

CONCLUSIONS

Considerable inconsistencies of decision-making exist among expert surgeons when choosing a therapeutic strategy for CRLM. This might confuse both patients and referring physicians and indicate that an international high-level consensus statements and widely accepted guidelines are needed.

Bariatric Surgical Simulation: Evaluation in a Pilot Study of SimLife, a New Dynamic Simulated Body Model

Background

The demand for bariatric surgery is high and so is the need for training future bariatric surgeons. Bariatric surgery, as a technically demanding surgery, imposes a learning curve that may initially induce higher morbidity. In order to limit the clinical impact of this learning curve, a simulation preclinical training can be offered. The aim of the work was to assess the realism of a new cadaveric model for simulated bariatric surgery (sleeve and Roux in Y gastric bypass).

Aim

A face validation study of SimLife, a new dynamic cadaveric model of simulated body for acquiring operative skills by simulation. The objectives of this study are first of all to measure the realism of this model, the satisfaction of learners, and finally the ability of this model to facilitate a learning process.

Methods

SimLife technology is based on a fresh body (frozen/thawed) given to science associated to a patented technical module, which can provide pulsatile vascularization with simulated blood heated to 37 °C and ventilation.

Results

Twenty-four residents and chief residents from 3 French University Digestive Surgery Departments were enrolled in this study. Based on their evaluation, the overall satisfaction of the cadaveric model was rated as 8.52, realism as 8.91, anatomic correspondence as 8.64, and the model’s ability to be learning tool as 8.78.

Conclusion

The use of the SimLife model allows proposing a very realistic surgical simulation model to realistically train and objectively evaluate the performance of young surgeons.

Training in Bariatric Surgery: a National Survey of German Bariatric Surgeons

INTRODUCTION

Skill in bariatric surgery has been associated with postoperative outcome. Appropriate surgical training is of paramount importance. In order to continuously improve training strategies, it is necessary to assess current practices.

AIM

To determine how German bariatric surgeons have been trained and to assess current training strategies.

METHODS

Between February 2017 and March 2017, an online census of surgeons registered as members of the German Society for Bariatric and Metabolic Surgery was conducted. A total of three reminders were sent out. Data were analyzed using descriptive statistics. Data was reported as median (interquartile range); percentages were adjusted for completed answers only.

RESULTS

A response rate of 51% (n = 214) was achieved. Surgeons reported a median of 14.5 (8-20) years of surgical experience after initial training, with a specific bariatric experience of 7 (4-13) years. The total cumulative bariatric case volume was 240 (80-500) cases, with an annual case volume of 50 (25-80). The most commonly applied approaches to bariatric skills acquisition were "learning by doing" (71%), "course participation" (70%) and "observerships" (70%). Fellowships and the use of operating videos were less frequently applied strategies (19%/ 47%). Interestingly, observerships (94%) and course participation (89%) were rated as very important/important, whereas "learning by doing" (62%), watching operation videos (59%), and fellowships (48%) were less frequently perceived as important/very important training strategies.

CONCLUSIONS

The majority of surgeons performing bariatric cases were senior surgeons with more than 10 years of post-training experience; nevertheless, the survey revealed a lack of structured approaches to bariatric specialization training.
