HPB fellowship training: consensus and convergence

Supply and demand of hepatopancreatobiliary surgeons in the United States

BACKGROUND

Hepatopancreatobiliary (HPB) surgery requires specialized training and adequate case volumes to maintain procedural proficiency and optimal outcomes. Studies of individual HPB surgeon supply related to annual HPB case demand are sparse. This study assesses the supply and demand of the HPB surgical workforce in the United States (US).

METHODS

The National Inpatient Sample (NIS) was queried from 1998-2019 to estimate the number of HPB procedures performed. To approximate the number of HPB surgeons, models based on previous HPB workforce publications were employed. We then calculated the number of HPB surgeons needed to maintain volume-outcome thresholds at current reported levels of centralization.

RESULTS

In 2019, approximately 37,335 patients underwent inpatient HPB procedures in the US, while an estimated 905-1191 HPB surgeons were practicing. Assuming 50% centralization and an optimal volume-outcome threshold of 24 HPB cases-per-year, only 778 HPB surgeons were needed. Without adjustment in centralization, by 2030 there will be a demand of fewer than 12 annual cases per HPB surgeon.

CONCLUSION

The current supply of HPB surgeons may exceed demand in the United States. Without alteration in training pathways or improved care centralization, by 2030, there will be insufficient HPB case volume per surgeon to maintain published volume-outcome standards.

Trends in pancreatic surgery experience in general surgery residency in the US, 1990–2021

BACKGROUND

We hypothesized a decline in resident pancreatic operative experience. The study assesses trends in that experience since 1990.

METHODS

Accreditation Council for Graduate Medical Education (ACGME) national case log data of general surgery residency graduates from 1990 to 2021 were reviewed. Collected and analyzed were the mean and median total number of pancreatic operations per resident, the mean number of specific case types performed, and the annual number of residency graduates. For selected procedures, the mean number of cases by resident role (Surgeon-Chief and Surgeon-Junior) was also analyzed.

RESULTS

Both the mean and median total number of resident pancreatic operations has declined since 2009 as have the mean number of several specific pancreatic case types, including resections. The annual number of residency graduates has significantly increased since 1990, and particularly since 2009.

CONCLUSIONS

Resident volume in pancreatic operations has significantly declined over the last decade.

The job market for HPB surgeons: leadership perspectives on surgeon skillsets, training pathways, and hiring

BACKGROUND

Three tracks prepare Hepato-Pancreato-Biliary (HPB) surgeons: HPB, surgical oncology, and transplant fellowships. This study explored how surgical leaders thought about HPB surgery and evaluated potential candidates for HPB positions.

METHODS

This descriptive qualitative study utilized interviews of healthcare leaders whose responsibilities included hiring HPB surgeons. We coded inductively then used thematic network analysis to organize the data. Individual codes formed basic themes, then larger secondary themes, then finally "primary" themes.

RESULTS

Primary themes were: (1) What defines an HPB surgical practice?, (2) How do they assess candidates for HPB positions?, and (3) How will HPB practices continue to evolve? Leaders assessed applicants' training, behaviors and cultural fit, technical excellence, and more. Personal recommendations and professional networks significantly influenced the hiring process. HPB surgery needs were growing due to population changes, treatments advances, and changing market conditions.

DISCUSSION

Surgical societies should focus on facilitating networking, promoting transparency, sharing quality data, providing evidence of technical skills and teamwork, mentorship, and providing guidance to general surgery residency program directors. There is great interest in unification and cooperation across the profession, protocol standardization enhancing quality, continued workforce diversification, and evaluation of the alignment between training and practice.

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.

Should Common Bile Duct Exploration for Choledocholithiasis Be a Specialist-Only Procedure?

Background: Common bile duct exploration (CBDE) is performed uncommonly. Issues surrounding its uptake in the laparoscopic era include perceived difficulty and lack of training. We aim to determine the success of CBDE performed by "specialist" and "nonspecialist" common bile duct (CBD) surgeons to determine whether there is a substantial difference in success and safety. Methods: A 10-year retrospective audit was performed of patients undergoing CBD exploration for choledocholithiasis. Northern Health maintains an on-call available "specialist" CBD surgeon roster to aid with CBDE. Results: Five hundred fifty-one patients were identified, of which 489/551 (88.7%) patients had stones successfully cleared. Specialists had a higher success rate (90.8% versus 82.6%, P = .008), associated with a longer surgical time. Method (transcystic or transductal), approach (laparoscopic or open), and indication for operation were similar between groups. There was no significant difference in complications. To be confident of a surgeon having an 80% success rate, 70 procedures over 10 years were required, however, an "in-control" 50% success rate may only require 1 procedure per year. Conclusion: While specialist CBDE surgeons have improved success rates, nonspecialist general surgeons also have a good and comparable success rate with an equivalent complication rate. With realistic annual targets, nonspecialist CBD surgeons should be encouraged to perform CBDE in centers without specialist support.

Fellows perspective of HPB training in Latin America

BACKGROUND

Currently, no standards for HPB training exist in Latin America. The aim of this work is to evaluate fellows' experience of HPB training and the areas of opportunity to improve.

METHODS

A 35 points survey was developed and distributed among fellows from dedicated HPB training programs in Latin America. The survey was applied by direct phone call (37%) or web based (63%), to fellows graduated between 2010 and 2014, from 7 different programs.

RESULTS

Thirty-nine fellows from Argentina, Brazil, Chile and México were considered with a response rate of 82% (32/39). Most fellows (90%) shared cases with more than one co-fellow. Scrubbing with chief residents ocurred to 60% of fellows; only 14% of fellows noted having a primary surgeon role in more than 70% of cases. Median number of major hepatectomies during training was 15 (1-100), Whipple procedures 6 (1-40), and major bile duct repair 20 (1-80). Limited funding was the main reason to avoid HPB programs outside the country of origin.

CONCLUSION

HPB training in Latin America requires more operative volume and autonomy. Financial burden is the main limitation to pursue training overseas. A multinational fellowship that takes advantage of each center may overcome differences in volume and type of cases.
